Preventive Maintenance: Optimizing Asset Performance and Longevity

<h2 id="isPasted">1. What is LoRaWAN?</h2>LoRaWAN is a standard within LPWA (Low Power Wide Area) wireless communication that uses the unlicensed band (sub-GHz band) that does not require a radio station license and features wide-area and long-distance communication as well as low speeds and low power consumption. LoRaWAN is a form of non-cellular LPWA that was established by the non-profit LoRa Alliance and recognized as an international standard by the International Telecommunication Union (ITU) in December 2021.LoRaWAN is a wireless network system that is used by connecting one or a small number of gateways with many end devices*1 equipped with a LoRaWAN module. LoRaWAN does not require a carrier communications network and it enables companies to build and operate their own networks, which makes it easy to introduce regardless of the application and business scale, and the number of users is increasing every year.*1 For example, communications devices that control device applications such as general lighting, cameras, and other sensors.<h3>1.1 Comparison of LoRaWAN (Non-cellular LPWA) and Cellular LPWA</h3>The LoRaWAN non-cellular LPWA standard is able to keep operating costs low compared to signing an agreement with a carrier and using their line. Furthermore, you do not need to consider the location where it will be used or whether stable communication with the carrier's base station is possible. In addition, because it enables you to build a complete network environment on your own, LoRaWAN can implement a private and secure wireless communications environment that is not mediated by the lines of an external operator.Reference: <a href="https://article.murata.com/en-global/article/what-is-lpwa-wireless-communication-1#section-55863" target="_blank">3.3 Cellular LPWA and Non-cellular LPWA Specifications Comparison｜What Is Low-Power Wide-Area (LPWA) Wireless Communication? - Basics</a><h3>1.2 Primary LoRaWAN Applications</h3>The primary applications of LoRaWAN include smart meters, smart cities, smart buildings, and enhancing the intelligence of public transportation in community infrastructure as well as support for IoT in the manufacturing industry, tracking of logistics cargo and people through location information, environmental sensing, smart agriculture, etc. Because it enables operation with a comparatively low cost that is not affected by the service area restrictions of carriers in contrast to cellular LPWA, LoRaWAN is attracting increased attention around the world as a means of wireless communication that is suitable for IoT and M2M in diverse fields.The following page introduces several examples utilizing LoRaWAN. <a href="https://article.murata.com/en-global/article/introduce-to-lorawan-2#section-59239" target="_blank">4. Examples of IoT Solutions Utilizing LoRaWAN｜LoRaWAN (Non-cellular LPWA) Primer – From Fundamentals to IoT Application Examples (2)</a><h2>2. LoRaWAN Communication Protocol Stack – Roles of LoRa and LoRaWAN –</h2>By looking at the communication protocol stack that is implemented, we can understand the features of those communication systems in many cases. (The communication protocol stack is explained in the&nbsp;<a href="https://article.murata.com/en-global/article/introduce-to-lorawan-1#section-59227" target="_blank">"Column – What Is the Communication Protocol Stack?"</a> section at the bottom of this page.) Figure 1 shows the LoRaWAN communication protocol stack. Here, we explain the LoRaWAN protocol stack as well as the respective meanings and roles of LoRa and LoRaWAN in the protocol.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzNzY5NjU3MzkxLWxvcmF3YW4xLWltZzAwMDFfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Figure 1 LoRaWAN communication protocol stack<h3 id="isPasted">2.1 What is LoRa (Physical Layer)?</h3>The "LoRa" shown in the Physical Layer at the bottom of Figure 1 is an abbreviation of "Long Range" and refers to the wireless modulation method developed by U.S. company SEMTECH based on CSS (Chirp Spread Spectrum), which is a type of spectrum spread technique. Furthermore, the LoRa ISM band*2 is established by country and region as shown in Table 1.<table><caption>Table 1 LoRa frequency band by region (partial)</caption><thead><tr><th>Region(country or territory)</th><th>Name</th><th>Frequency band(MHz)</th></tr></thead><tbody><tr><td>Europe</td><td>EU868/EU433</td><td>863-870/433-435</td></tr><tr><td>U.S.</td><td>US915</td><td>902-928</td></tr><tr><td>China</td><td>CN779/CN470</td><td>779-787/470-510</td></tr><tr><td>Japan</td><td>AS923</td><td>920-928</td></tr><tr><td>Australia</td><td>AU915</td><td>915-928</td></tr><tr><td>India</td><td>IN865</td><td>865-867</td></tr><tr><td>Indonesia</td><td>AS2</td><td>923-925</td></tr><tr><td>South Korea</td><td>KR920</td><td>920-923</td></tr><tr><td>Malaysia</td><td>AS1</td><td>920-923</td></tr><tr><td>New Zealand</td><td>AU915</td><td>915-928</td></tr><tr><td>Singapore</td><td>AS1</td><td>920-923</td></tr><tr><td>Taiwan</td><td>AS2</td><td>923-925</td></tr><tr><td>Thailand</td><td>AS2</td><td>923-925</td></tr></tbody></table>*2 The ISM band is a frequency band established by the International Telecommunication Union (ITU) that can be used without a license in the fields of industry, science, medicine, etc. The ISM band includes frequency bands that are universal and those that are region (country and territory) specific. The latter type of band is established for LoRa.<h3 id="isPasted">2.2 What is LoRaWAN (MAC Layer)?</h3>The MAC*3 Layer LoRaWAN is the name of the non-cellular LPWA standard while also referring to the LoRaWAN network communication protocol (rules of communication). Under LoRaWAN, each end device connects to the gateway via the MAC (Device ID) without an IP to communicate wirelessly.Moreover, the MAC options include Class A, Class B, and Class C, which differ in terms of the upstream and downstream communication schemes and intervals in the two‐way communication between each end device and the gateway as well as the switching behavior of the receiving slot on the device side related to power consumption, etc. The low power consumption Class A is often used when running a device with a battery for a long period of time with little reception standby time on the device side. At the same time, other classes can be separately used according to the objective and environment such as when communicating with low latency while continuously supplying power to the device, etc.*3 MAC is an abbreviation of "Media Access Control," and within the hierarchical communication protocols, it establishes methods for signal transmission timing control, the division of data to be transmitted, the assembly (transmission) and disassembly (reception) of frames with a destination address and other added control data, error detection, etc. in addition to the definition and allocation of the MAC address, which identifies devices.<h2>3. LoRaWAN Network Construction – Configuration of the LPWA Devices, Gateway, Servers, etc. –</h2>Because LoRaWAN is a non-cellular LPWA standard, it does not use carrier base stations and communications networks, as is the case in the wireless communications of cellular LPWA devices. Under LoRaWAN, data communication is carried out wirelessly between the LoRaWAN-compliant gateway and the end devices including sensors equipped with LoRaWAN modules, etc. Data is transmitted through this gateway to the network and application servers, etc., which run on communication protocols that differ from the LoRaWAN network. The example below introduces a primary network built using LoRaWAN.<h3>3.1 Example of Building Your Own LoRaWAN Network</h3>Because non-cellular LPWA does not require a radio station license, it enables companies to build a system on their own by preparing the LoRaWAN-compliant gateway, network servers, and application servers, etc. in addition to the end devices equipped with LoRaWAN modules.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzNzY5NzA1NjA2LWxvcmF3YW4xLWltZzAwMDJfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Figure 2 Example of building and operating your own LoRaWAN networkAs shown in Figure 2, the advantage of a LoRaWAN network is that it enables use of a private and secure wireless solution by building and operating the entire network oneself. Furthermore, while in some cases each server may be hosted on premises (internal environment), in other cases a cloud server contracted by the company may be used.<h3>3.2 Example of Building a LoRaWAN Network Using a Vendor</h3>In cases where it is not suitable to build a LoRaWAN environment on your own, such as usage for a specific period of time or if you lack the internal system integration or networking personnel, an alternative method is to use a vendor who sells or rents gateways that support the LoRaWAN communication protocol and offers cloud services, etc.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzNzY5NzI2NzkyLWxvcmF3YW4xLWltZzAwMDNfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Figure 3 Example of building a LoRaWAN network using vendor servicesAs shown in Figure 3, there are cases in which a company may sign a fee-based contract with a vendor for a LoRaWAN-compliant gateway and network servers or application servers according to the circumstances. The service details differ by vendor, but the ability to entrust the gateway implementation, server maintenance, etc. to the vendor is an advantage of such contracts. Furthermore, when it comes to LoRaWAN-compliant gateways that can connect and communicate with many devices, there are gateways that can only be used by the subscriber as well as plans that reduce usage fees by sharing a gateway between multiple subscribers.Moreover, cloud services are typically provided with the exception of the gateway. A monthly fee is required when subscribing to a gateway and servers. However, compared to cellular LPWA, which requires a mandatory contract with a carrier to use the cellular phone communication network, the service usage fees for network server vendors, etc. required to operate the LoRaWAN non-cellular LPWA standard are said to be low.<h2>Column – What Is the Communication Protocol Stack?</h2>Regardless of whether they are wireless or wired, telecommunications function by conforming to communication protocols (Reference:&nbsp;<a href="https://article.murata.com/en-global/article/basics-of-wireless-communication-2#section-58505" target="_blank">6. What Is a Communication Protocol?｜Basic Knowledge of Wireless Communication: Wireless Mechanism (2)</a>). Table 2 shows the role and correspondence of each layer of the communication protocol stack in the LoRaWAN model and the OSI Reference Model*4.<table><caption>Table 2 OSI Reference Model and the role of each layer, LoRaWAN model</caption><thead><tr><th colspan="2">OSI Reference Model</th><th>Roles and Examples</th><th>LoRaWAN model</th></tr></thead><tbody><tr><td colspan="2">Application Layer</td><td>Defines the functions that are required as an &nbsp; application such as sending and receiving files, &nbsp; etc. (HTTP, FTP, DNS, SMTP, POP, etc.)</td><td>Application</td></tr><tr><td colspan="2">Presentation Layer</td><td>Defines (SMTP, FTP, Telnet, etc.) &nbsp; the data expression format &nbsp; (encryption method, character code, etc.)</td><td rowspan="4">-</td></tr><tr><td colspan="2">Session Layer</td><td>Defines the steps related to the start and &nbsp; end (login and logout, etc.) of &nbsp; communication (TLS, NetBIOS, etc.)</td></tr><tr><td colspan="2">Transport Layer</td><td>Rules that ensure communication quality such &nbsp; as error detection and recovery in transmitted &nbsp; and received data (TCP, UDP, NetWare/IP etc.)</td></tr><tr><td colspan="2">Network Layer</td><td>Defines functions for relaying to different &nbsp; networks (IP, ARP, etc.)</td></tr><tr><td rowspan="2">Data Link Layer</td><td>MAC Layer</td><td rowspan="2">Defines the control procedures for &nbsp; transferring data (Ethernet, etc.)</td><td>LoRaWAN MAC&nbsp; (Class A / Class B / Class C)</td></tr><tr><td>LLC Layer</td><td>-</td></tr><tr><td colspan="2">Physical Layer</td><td>Defines connector shapes and other physical &nbsp; specifications (RS232C, etc.) for transferring &nbsp; data to communication channels as well as &nbsp; modulation systems in the case of wireless</td><td>LoRa modulation</td></tr></tbody></table>*4 The OSI Reference Model is an international standard model for a protocol stack. Currently, the protocol stack of this model is not directly used. However, because it is the fundamental reference model for the protocol stack, it is often compared to the various protocols that are implemented in devices.Table 2 shows that the LoRaWAN model stack has three layers while the TCP/IP model, which is the communication protocol of the Internet, has four layers, so we can see that the LoRaWAN model has a simpler protocol configuration. This means that it is easier to update the protocol and leads to improved response times.<hr id="isPasted"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713769894367-1713769894367.png" class="fr-fic fr-dii">If you have any questions based on this article that you would like to discuss with an expert at Murata, don't hesitate to reach out.

Harnessing cutting-edge technology to optimize energy efficiency, comfort, and security in modern buildings

Building Management: The Power of Building Automation Systems

Consider the following details when conducting power profiling:<ol start="1" type="1"><li>Hardware and sensor configurations: Analyze the components and sensors used in the device and their power consumption characteristics.&nbsp;Understand how different hardware configurations impact energy usage.</li><li>Firmware settings: Examine the firmware settings and configurations to identify any potential areas where power consumption can be optimized. Adjust settings and parameters to achieve more efficient power usage.</li><li>Communication parameters: Evaluate the communication parameters used by the device, such as transmission frequency and data rate. Analyze how different communication settings affect power consumption and battery life.</li><li>Use cases and corner cases: Consider the different use cases and scenarios in which the device will be deployed. Investigate how the device's behavior and power consumption vary under different conditions. Pay special attention to corner cases that may have unique power consumption patterns.</li></ol>Continuous benchmarking is crucial throughout the product development process. Utilize UART clever printouts and correlate them with power consumption to identify specific components or features that may be draining energy. This analysis will provide valuable insights on areas that can be optimized for improved power efficiency. Remember to turn off UART once the analysis is complete to avoid any impact on the final product.Additionally, consider network variables that can impact power consumption. Import network log files to understand how factors like distance to the gateway or Node B, weather conditions, and device density within the network influence power consumption. These variables can significantly affect how the battery is drained and should be taken into account when estimating battery life.By iteratively calculating battery life based on power consumption profiles throughout the development project, developers gain valuable knowledge and intuition about the factors that affect the power profile. This understanding allows them to maintain the desired power profile despite changes in the development stack, ensuring optimal power usage and battery life.<h2>Refined battery selection with battery profiling</h2>Understanding the power consumption behavior of an IoT device goes beyond relying solely on data sheet information. It involves conducting a critical analysis to assess the battery's performance in the unique scenario relevant to your project. This process provides insights into the battery's efficiency, stability, and suitability for the deployment.<h2 id="isPasted">Defining a Battery Profile</h2>A battery profile is not just a general overview; it is a tailored description of how a battery discharges under specific loads in particular environments. You can find such profiles in the battery's data sheets. To select the ideal battery for your solution, you need to <a href="https://www.qoitech.com/battery-toolbox/" target="_blank">create profiles</a> that align with your device's power requirements. Additionally, it is beneficial to profile several battery alternatives from different brands, batches, and temperatures to gain a thorough understanding of their behavior.<img border="0" width="605" src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713351007606-1713351007606.jpeg" alt="En bild som visar skärmbild, Multimedieprogram, programvara, GrafikprogramvaraAutomatiskt genererad beskrivning" class="fr-fic fr-dii">By following these steps, you can gain a deeper understanding of the power consumption behavior of your IoT device and make informed decisions when selecting the most appropriate battery for your project.<h2>Accelerated Battery Profile</h2>To create a battery discharge profile that aligns with your device's current consumption profile, you may need several months or even years. Thus, it is essential to develop an accelerated discharge profile. Here are some best practices to create an accurate and helpful profile:Maintain High Discharge Consistency: Coin cell batteries are particularly sensitive to high discharge, so it is crucial to match your device's peak current. Lithium-ion rechargeable batteries can withstand higher discharge currents, while alkaline batteries fall in between.Shorten Cycle Time: Determine the low discharge time the battery requires to recover.Increase Sleep Current: Ensure the battery can recover even in high discharge. Consult with Manufacturers: Seek assistance from battery manufacturers to verify your assumptions for the batteries you want to profile.<h2>Accuracy Considerations</h2>It's worth noting that precisely matching the discharged energy in the accelerated profile to the original profile may not be feasible, which could affect the profile's accuracy. The less acceleration used, the more accurate the results, but this method's level of accuracy is usually adequate for IoT implementations. It ensures a comprehensive real-world understanding of the battery's performance, contributing to successful IoT solutions.<h2>Profiling Different Battery Chemistries</h2>Here is an example from a customer case with LoRaWAN waste management IoT device. For this specific application, we profiled two distinct electro-chemistries encompassing six brands, including multiple samples from each brand. The profiling was carried out at room temperature, using an accelerated battery profile developed with input from battery manufacturers. Comparing samples from multiple manufacturers allowed us to evaluate how different form factors and chemical compositions influenced the results. Profiling the batteries in various environments could be the next logical step to observe the available capacity deviation from these controlled profiles, given that the profiling occurred at room temperature.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713351055997-otii-arc-battery-profiling.png" style="width: 100%px;" class="fr-fic fr-dib">Battery profiling set-up with Otii Arc ProBattery Profile AnalysisLM17500: Three samples of this battery were profiled, yielding an average capacity of approximately 3050 mAh before reaching the cut-off point, slightly higher than the data sheet capacity of 3000 mAh.CR123A: Two batteries were profiled, with an average capacity of about 1600 mAh, consistent with the data sheet for that specific temperature.Interestingly, alkaline batteries exhibited significant variations in available capacity based on the manufacturer, which is a crucial consideration if customers will be responsible for battery replacement.AAA: These batteries had capacities ranging from 1080 to 1150 mAh, with an average of around 1100 mAh. The data sheet indicated a capacity of 1200 mAh.AA: The AA batteries showed a wider range of capacities, from 2420 to 2730 mAh, with an average of approximately 2590 mAh. For example, the data sheet for Varta indicated a capacity of 2950 mAh.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713351084975-battery.png" style="width: 100%px;" class="fr-fic fr-dib">Batteries profiled in this studyOur profiling process identified performance nuances across different battery brands, chemistries, and form factors. These insights are crucial for making informed decisions specific to the device and use case, going beyond the data sheet capacities. Conducting profiling in diverse environmental conditions, particularly temperature, could further enhance our understanding and contribute to a more resilient IoT device design.

By directly applying the profiled battery discharge to the device instead of using a standard power supply, you can determine the actual usable capacity and further enhance the accuracy of the estimation. The actual usable capacity depends on the behavior of the device itself, and in some cases, we have encountered as low as 20% of the measured capacity. Tools such as <a href="https://www.qoitech.com/otii-ace/" target="_blank">Otii Ace Pro</a> with <a href="https://www.qoitech.com/battery-toolbox/" target="_blank">Battery Toolbox</a> can replicate these battery profiles, effectively serving as profiled batteries for the IoT device. By adjusting the used capacity in the battery emulator of these instrumentsand monitoring when the device either shuts down or reboots, you can uncover the true, realistic usable capacity. This ensures a more precise understanding of the battery's potential in the context of the specific application.<img border="0" width="605" src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713351148170-1713351148170.png" alt="Battery emulation with OtiiBattery Toolbox. MEasured and saved battery profile can be replayed to mimic the actual usable capacity and battery behaviour." class="fr-fic fr-dii">Battery emulation with Otii Battery Toolbox<h2>Conclusion</h2>We propose a technique for selecting the ideal battery: initial selection based on a defined use case and data sheet, power profiling of the IoT device and the battery for the use case, and a refined battery selection using device power behavior to assess the battery's real-world performance for the specific use case and device. This nuanced approach enables developers to make well-informed decisions that boost battery life.

Once the first prototype of your IoT device becomes available, it is essential to start power profiling and estimating battery life. This process involves gaining a comprehensive understanding of the device's configuration and power consumption characteristics within its specific deployment context.

Steering IoT Innovation in Global Asset Expeditions and Fleet Journeys

While embedded systems tend to lack the processing horsepower of servers or even modern personal computers, the sheer number of devices is making them an increasingly valuable target for bad actors looking to run illegal botnets and cryptocurrency mining operations. One of the first major security-related wake-up calls for embedded system designers was the 2016 Nest thermostat botnet attacks. Given the consumer-facing nature of the particular Internet of Things (IoT) coupled with an increased sensitivity regarding privacy and security; the Nest botnet caused a huge amount of discussion. Those discussions tended to center on how companies should build security into their low-cost IoT products and how consumers can safely operate the devices in their homes and businesses.With the growing threat of cyberattacks, it is essential that developers keep security considerations in mind throughout the design process. By following some practical tips and recommendations, developers can guard against a wide range of attack scenarios. Read on for an outline of security measures developers can use in their embedded designs.<h2>Build Secure</h2>While there are numerous chip architectures, operating systems, and communications protocols; many IoT devices tend to be built around Arm®-based architectures, and if they run an OS it tends to be a Linux distribution. This commonality is good in many ways; lower costs and faster development times; it also comes with quite a few negatives. Attack vectors tend to become “one-size-fit-all”, especially for devices running a Linux-based OS. To mitigate the threats associated with widespread devices that share a common architecture, developers should implement the following “quick win” security design principles:<ul><li>Do NOT hardcode passwords into the firmware. Also, do not use a common default password for all devices. Require the user to create a custom username and password during device initialization.</li><li>Do NOT enable insecure protocols such as HTTP, FTP, or Telnet by default. Data going off the device via wired or wireless protocols must be strongly encrypted. Avoid “homebrewed” encryption solutions.</li><li>Ship the device with the most restrictive configuration possible and let the end-user make a proactive decision to reduce security-related settings.</li><li>All mechanisms used to access the devices should require authentication and authorization controls. Two-factor authentication (2FA) should be used if practical.</li><li>All user-facing inputs should be filtered to avoid injection-type attacks.</li><li>Implement a secure device management interface for the end-user that will allow them to manage their assets, update devices, monitor devices, and securely decommission the devices that have reached their end-of-life (EOL).</li><li>Over-The-Air (OTA) update mechanisms must be validated on-device. The update files must be sent encrypted en route to the device. Lastly, ensure there are anti-rollback features to prevent a device from being reverted to a previous, insecure firmware.</li><li>If third-party software libraries are used in the design of your device, they must be continually monitored to ensure that third-party updates are integrated and that they do not become deprecated. Abandoned software projects can become nasty vulnerabilities for your device. Change the third-party software default passwords before committing them to your project.</li><li>Limit what sensitive data should be stored on the device. Store such information in a secure enclave only.</li><li>Remember that with the IoT that embedded systems are only one part of a larger ecosystem. Ensure that security is built into the cloud, desktop, and mobile applications as well. Ecosystem security is only as strong as the weakest link.</li><li>Consider establishing a bug bounty program to encourage end-users and security researchers to submit flaws in a secure, responsible manner.</li></ul>Physical access to a device tends to be the game-over situation for devices. That doesn’t mean that there aren’t things that can be done to make it harder physically exploit these types of devices. Entire books have been written on making circuit boards and associated enclosures tamper-resistant but for a few “quick wins” consider the following physical design rules-of-thumb to harden your device:<ul><li>Pins for debugging ports such as JTAG and UARTs are very useful when developing and testing a device. They are also tempting targets for those seeking to reverse engineer a device with ill-intent. Obfuscating these pins and/or removing header pins for production units is recommended. Note that this will come at the expense of making it more difficult to troubleshoot once fielded. Designers must consider a balance between security and maintainability.</li><li>The use of adhesives, ultrasonic welding, and/or specialty security screws can make it more difficult to open a device.</li><li>Applying a non-conductive epoxy over sensitive components can obfuscate their identity and purpose.</li><li>You might be tempted to use older components that might have vulnerabilities. Be aware of the counterfeit components as well. If a deal seems too good to be true, it probably is. Balancing security and time-to-market considerations is not a decision to be taken lightly.</li><li>Multilayer boards can be used to route traces in a way that makes it harder to discern how the board functions.</li></ul>Some of the following recommendations might be a bit much for consumer-grade IoT devices. However, as we will elaborate on later, industrial control systems and defense systems would likely benefit from these more robust physical security measures:<ul><li>Build security features into the board itself, such as microswitches, mercury switches, or magnetic switches that can detect if a board is being unintentionally handled or opened. Nichrome wire or fiber optics can also be used. If the wire or fiber is negatively impacted by someone trying to tamper with a device, then there will be a detectable change in the current flow of the wire or the behavior of photons through the fiber.</li><li>Side Channel or glitching attacks, while perhaps not common, provide a unique advantage to adversaries in that they use the laws of physics against a device and thus are very difficult to prevent though can be detected. By attacking the timing or restricting the flow of electrons to a CPU, it’s possible to get a device to act in unintended ways that negate security features. Voltage and current sensors can be implemented onboard circuit boards to detect if glitching may be occurring, though there is potential for false positives.</li><li>Significant adversaries can employ x-ray machinery to peer into microchips and discover the topography of the transistors to determine function and more. Sensors that detect x-rays can be added to detect tampering, though can do nothing to prevent an adversary from extracting useful information.</li></ul>It should be noted that there is quite a dichotomy between the paradigms of security and openness. Security values obfuscation. Open hardware values understanding. Regardless, keep in mind the old adage that locks only keep honest people honest, and so too with security-at-large. For more information on how to build secure IoT devices, visit the Open Web Application Security Project (OWASP) IoT Project.<h2>Operate Secure</h2>Even if a manufacturer could implement all the best secure design principles in their product, they would be mostly for naught if the end-user does not operate their device in a secure manner.<ul><li>Change the default router name, router password, network name (SSID), and network encryption key. Be sure to use strong password principles and do not use the same password for both networks.</li><li>Segment your home network into two “virtual” networks so that IoT devices cannot be “seen” by the desktop computers, Network Attached Storage (NAS) devices, etc. To do this quickly and easily, use the guest network feature for your IoT network.</li><li>Most IoT devices rely on a smartphone app to control the device. Keep the app up to date and use 2FA for login if available.</li><li>Disable any features of your IoT devices that you do not intend to use.</li><li>Update the firmware of both your router and IoT devices on a regular basis.</li><li>When an IoT device reaches the end of life and no longer receives updates consider replacing it with a newer model.</li></ul><h2>Industrial Strength Security</h2>Consumer-facing IoT products may be plentiful, but their industrial counterparts, collectively referred to as Industrial Control Systems (ICS) manage numerous extremely important and potentially dangerous processes. Everything from energy production to factories uses embedded digital technology (referred to as Operational Technology or OT; in contrast to office-centric Information Technology or IT) to control the facilities and associated machinery responsible for performing the various processes. The ICS environment is sufficiently different from a strict IT environment that special considerations for hardening OT devices and ICS networks are warranted. The most fundamental principle is that ICS should not have a connection to the internet. While this seems like a no-brainer, it is surprising how often this fundamental rule is violated. For more information on how to secure ICS networks and devices, there are two security frameworks you should review: MITRE ATT&amp;CK for ICS and the MITRE ATT&amp;CK for Enterprise.The nature of where ICS systems are typically found (e.g., areas that are environmentally, chemically, or otherwise hazardous) means ICS has been designed to prioritize the availability of the systems over confidentiality. From a positive perspective, this typically means there are redundant systems, and those systems are designed to fail safely. However, ICS systems can be left in operations for several decades and may not always be kept up-to-date. In addition, many of the protocols are older and were built with efficiency, not security in mind. Bottom line, security in the ICS or IIoT space is uniquely challenging and best practices may be difficult to implement. However, embedded developers for such machinery should be cognizant of the need to modernize their design practices and incorporate security into future designs and not treat it as a bolt-on afterthought.

Practical Tips for Embedded System Security

For thousands of years, humans have been building houses, roads, bridges, and markets that allowed us to live safer and more productive lives. But the tools of the trade have lacked the capability to let us do so as effectively as possible. &nbsp;Now, belatedly but perhaps inevitably, smart connectivity is helping to lay the foundations for improved productivity and worker safety in the all-important architecture, engineering, and construction (AEC) industry. To that end, technology companies are introducing a wide range of innovative products to power connected construction. &nbsp;<h2>The&nbsp;critical role of the&nbsp;building&nbsp;sector&nbsp;</h2>From humble beginnings, construction has culminated in giant cities where 55 percent of the world’s population resides, a figure, according to the UN, that’s set to rise to 68 percent by 2050.&nbsp; Today, the AEC sector is the largest in the global economy, responsible for employing around seven percent of the world’s working population, and about 13 percent of world’s GDP ($10 trillion) according to analyst McKinsey. And because around 50 percent of a construction project’s total cost relates to labor, &nbsp;skilled workers are the key to a project’s success.&nbsp;<h2>Tech&nbsp;provides a&nbsp;solution&nbsp;to productivity challenges&nbsp;</h2>Yet despite its importance, the construction industry has earned a reputation for being slow to innovate. As a result, the sector has often suffered from severe productivity challenges.&nbsp;Technology offers a solution for raising the game. The signs are promising; digital adoption is accelerating on the back of strong demand for more infrastructure, a shortage of skilled labor, and increased expectations for data transparency and integration. An estimated $50 billion was invested in AEC tech between 2020 and 2022—85 percent higher than the previous three years—according to the latest McKinsey research.&nbsp;Growth is being driven by increased uptake of the IoT, big data analytics, and AI, as well as a greater emphasis on sustainability. That’s allowing companies to take advantage of real time field reporting by connecting and tracking materials, equipment, and workers at the construction site.&nbsp;<h2>Enhanced productivity&nbsp;boosts the bottom line&nbsp;</h2>A construction project manager can now access a management platform with real-time project data and task alerts. This information enables fast decisions and speeds up workflows from the back office to the field, and onwards to the extended project team. And it removes the project silos that limit collaboration. These practices will also lead to improved margins.&nbsp;&nbsp;Connected construction offers several other advantages over manual operations. For one, it can improve communication and transparency on the worksite; for example, consider a worker reporting back to a supervisor via a smart device, or sensors and tags embedded in equipment providing key updates such as the location and status of a concrete mixer. Or connected vehicles like dump trucks, backhoe loaders, excavators, and mobile cranes, could enable location detection and monitoring of usage via embedded cellular and GNSS technology.&nbsp;&nbsp;<h2>Monitoring essential construction materials&nbsp;</h2>A critical requirement for the construction industry is monitoring essential construction materials like concrete for quality control. This requirement led German company ConcR to develop a&nbsp;<a href="https://www.nordicsemi.com/Nordic-news/2023/11/The-ConcR-Box-employs-Nordic-Semiconductors-nRF9160-SiP" target="_blank">material monitoring solution</a>&nbsp;that analyzes the characteristics of concrete as it cures, to check when it’s safe to proceed with the next stage of construction. The ConcR Sensors are attached to a rebar (a reinforcing steel bar used to strengthen concrete slabs) before the concrete is poured. The sensors provide key insights into the strength and durability of the cement or concrete by monitoring temperature, relative humidity, residual moisture, pH, and chloride levels.&nbsp;&nbsp;The Nordic&nbsp;<a href="https://www.nordicsemi.com/Products/nRF9160" target="_blank">nRF9160 SiP</a>-powered&nbsp;<a href="https://www.nordicsemi.com/Products/Wireless/Low-power-cellular-IoT" target="_blank">cellular IoT</a>&nbsp;solution provides data across the lifecycle of concrete and screed—a levelled layer of material applied to a floor or other surface—starting from construction until 25 years in operation. With this information, planners, engineers, contractors, and owner-operators gain data-informed insights about the condition of construction materials throughout their life.&nbsp;<h2>Putting worker safety&nbsp;first and foremost&nbsp;</h2>Beyond productivity gains, technology is essential to the safety of skilled construction workers on hazardous worksites.&nbsp;&nbsp;For example, by using sensors integrated into existing personal safety equipment such as hard hats, WakeCap Technologies’ solution connect workers across entire job sites.&nbsp;<a href="https://www.nordicsemi.com/Nordic-news/2021/01/Wirepas-Mesh-hard-hat-sensor-locates-wearer-across-large-sites-and-reports-activity-incidents" target="_blank">WakeCap</a>&nbsp;is a wearable product designed to overcome the challenge of “digitizing the construction sector’s field logistics and workforce”, according to the company. In operation, the hard hat-worn sensors track the wearer’s location and record knocks to the hard hat. In addition, WakeCap’s analytics compare the on-site work crew timing with staffing and project management plans, highlighting any unexpected problems early - helping avoid delays and extra costs.&nbsp;Thanks to wireless tech, construction equipment, vehicles, devices, personnel, and locations will communicate and work together using emerging connectivity platforms. Connected construction is here and the world is better for it.&nbsp;

Smart connectivity is helping to lay the foundations for improved productivity and worker safety in the all-important architecture, engineering, and construction (AEC) industry. To that end, technology companies are introducing a wide range of innovative products to power connected construction.

Unlocking Efficiency: The AI-Powered Tiny Code Reader by Useful Sensors

The global transition to&nbsp;electrified personal transport is gaining momentum, with consumer electric vehicles (EVs) leading the way. According to the International Energy Agency (IEA), EV sales exceeded 10 million units in 2022.That total made up 14 percent of all new cars sold - up from less than 5 percent in 2020[1]. This shift is being driven by a combination of financial incentives and regulations, as governments across the globe commit to an EV future as part of a drive toward “net zero” carbon emissions.&nbsp;But there’s a danger that growth could be stifled by a significant issue: across the globe, EV charging stations lag vehicle sales.&nbsp;<h2>The need for accessible EV charging</h2>In countries where EVs are already popular, there tends to be well developed infrastructure; for example, Norway (where 86 percent of new cars are EVs) and Iceland (72 percent) have widespread charging networks. In contrast, the U.S. is falling behind in EV adoption—with the cars making up only five percent of new sales—removing the commercial incentive for companies to build charging infrastructure.&nbsp;Currently, the number of U.S. EV charging stations falls well below the availability of traditional gas stations, even when considering the size EV fleets compared to gas-powered vehicles. According to&nbsp;Motor.com, the U.S. averages about 104 gas pumps per 1,600 road kilometers, compared to just 22 EV charging ports[2]. The problem is made worse because it takes just minutes to fill a car from a gas pump—making it quickly accessible to the next vehicle in the line—while EV charging is much slower even with the latest generation of fast chargers. &nbsp;&nbsp;<h2>Avoiding flat batteries</h2>The limited availability of charging stations means that the last thing any EV driver needs is poor equipment reliability. Because EV drivers tend to plan road trips around the relatively few available charging stations when the roll up at one, they need it to work. And it’s not just consumers, governments too expect well maintained networks. For example, a new UK law, the&nbsp;Public Charge Point Regulation 2023, requires each charging point to be 99 percent reliable.&nbsp;&nbsp;To keep public charging points functioning that dependably, they need to be continuously monitored so that any problems can be quickly identified and fixed. Better yet, the monitoring could be used to address problems well before they result in equipment failure.&nbsp;&nbsp;Such monitoring requires robust, country-wide, and long-range wireless connectivity to collect data on the availability and condition of charging stations. And the only standards-based technology that can do this is&nbsp;<a href="https://www.nordicsemi.com/Products/Wireless/Low-power-cellular-IoT" target="_blank">Cellular IoT</a>. The technology enables companies to send EV charger data to a Cloud platform for remote analysis and to determine if the charger needs a visit for a service.&nbsp;<h2>Wireless connectivity for home charging</h2>The year-on-year increase in range of EVs promises to make home charging just as significant as public charging because it means that for all but the longest journeys, consumers can top up batteries in their own garage. This private market is made up of a range of individual suppliers, with two main types of home chargers. One type is low-cost and without Internet connectivity; despite the price advantage, this type may become less popular in the future due to inconveniences such as not being able to take advantage of flexible tariffs.&nbsp;The other popular type of home EV charger can access the Internet. The charger can be directly connected using Cellular IoT; alternatively, the charger can access the Internet via home Wi-Fi. With the introduction of the latest version of the wireless tech, Wi-Fi 6, the chargers can be easily integrated into the smart home ecosystem. This is because Wi-Fi is a key constituent of Matter, a smart home standard backed by companies such as Apple, Google, Samsung, and Nordic Semiconductor.&nbsp;&nbsp;As an integral part of the smart home, the domestic EV charger can, for example, ask the owner if a full charge is necessary for tomorrow because on that day of the week the car is usually only driven on short journeys. If a full top-up is asked for, connectivity allows the charger to determine precisely when to switch on charging to take advantage of the cheapest tariff. &nbsp; &nbsp;&nbsp;<h2>EV charging is set to become big business</h2>While public charging infrastructure remains relatively scarce, as EV ownership grows, so will the supporting network. And that will mean hundreds of thousands of chargers spread across entire countries. Cellular IoT is the only LPWAN capable of the coverage and reliability demanded by such huge charging networks. But more than that, cellular IoT brings other benefits.&nbsp;&nbsp;According to report published by telecoms services and equipment provider, Ericsson, connectivity brings significant business opportunities for EV charging companies and the related ecosystem. By connecting charging stations with cellular IoT, EV charging companies are better positioned to effectively manage their orchestration, administration, and maintenance. That in turn keeps the complex ecosystem of stakeholders—including drivers, hardware and connectivity providers, utility companies, automotive OEMs, and asset owners like parking operators, city authorities, and homeowners—satisfied.&nbsp;&nbsp;EV’s promise a greener future. But each driver wants reassurance that when they need to recharge their vehicle’s batteries, a fully functioning charger will only be a short hop away. Wireless technologies like cellular IoT and Wi-Fi will not only make it simple for service providers to keep their chargers in good order but will also help them efficiently and remotely manage huge charger networks. &nbsp;&nbsp;<hr><h3>References</h3>1.

Improving EV charging networks with cellular IoT

Battery Type: Electrochemistry, Capacity, and Energy DensityConsider the application and device form factor when choosing the battery. Coin cell batteries are compact and suitable for low-power devices with minimal energy needs but have limited capacity and are non-rechargeable. Lithium-ion (Li-ion) or lithium-polymer (Li-poly) batteries offer higher capacity, rechargability, and longer lifespans, making them suitable for devices with higher power demands and longer lifecycles. Customized batteries may be necessary for devices with unconventional form factors.Capacity, measured in mAh or Wh, refers to the amount of charge a battery can store, while energy density relates to the amount of energy stored per unit volume or weight. Selecting a battery with sufficient capacity and energy density ensures extended device operation without frequent battery replacements.Voltage and Discharge CharacteristicsEnsure the battery voltage aligns with the device's voltage requirements over its entire lifespan. Understand the discharge rate influenced by the application's use, such as data transmission frequency, intensity, and duration. These factors impact battery characteristics, including discharge rate and voltage drop over time, ultimately affecting power consumption and runtime.TemperatureTemperature significantly affects battery performance. Extreme temperatures can impact capacity, discharge rate, and lifespan. Select a battery with an operating temperature range suitable for the device's environmental conditions.Battery and Device Shelf LifeConsider battery conditions, such as self-discharge, both before integration into the IoT device and once integrated. Aging and self-discharge affect performance, so understanding these parameters during product development and post-market deployment is crucial.Cost and LifespanEvaluate upfront cost and total cost of ownership over the battery's lifespan. Assess the battery's expected lifespan and balance it with the device's operational duration to optimize cost-effectiveness.By considering these factors, developers can choose the right battery for their IoT devices, ensuring optimal performance, longevity, and cost-effectiveness. Relying solely on data sheets is not sufficient. Further tests need to be done due to the device-specific conditions and batteries. This will be adressed in the following blogpost. If you can’t wait, download the&nbsp;<a href="https://www.qoitech.com/whitepaper/powering-iot-devices/" target="_blank">white paper</a>.

Choosing the appropriate battery for IoT devices is critical to ensure optimal performance and longevity. There are several factors to consider when selecting a battery that aligns with the specific requirements of the application, allowing for reliable and long-lasting power supply.

Choosing the Right IoT Battery

For some IoT products, connectivity failure is a momentary inconvenience. For others, it’s a disaster.Imagine losing temperature data for a shipment of vaccines at a critical moment; there goes your cold chain compliance. Or think of a smart car’s accident detection and alert system. If the driver encounters a problem outside your cellular coverage area, disconnection can create life-threatening delays for responders.Looking forward, universal connectivity will be essential for self-driving vehicles—and a whole universe of yet-to-be-imagined technology. While cellular connectivity is already strong for&nbsp;<a href="https://www.mobileconnectivityindex.com/index.html" data-wpel-link="external" target="_blank" rel="external noopener noreferrer">populated areas and large parts</a> of North America, South America, Europe, and Asia, there are still gaps that affect global operators.The lack of coverage is particularly impactful for the agriculture and maritime industries, in which IoT devices continually move in and out of cellular signals. But for any or all mobile IoT, universal coverage is the ultimate prize. Today, a merger of technologies puts it within reach.The addition of satellite networks to cloud-based cellular connectivity is the key to global coverage. Here’s how satellite-cellular integration can make location-based connectivity loss a thing of the past.&nbsp;<h2>Satellite Non-Terrestrial Networks in Cellular IoT</h2>The simplest, most cost-effective way to keep your IoT deployments connected is with the help of a connectivity partner. These connectivity-as-a-service cloud providers offer access to many cellular networks at once, getting close to a global connection with one SIM and self-service fleet management tools.However, even the most well-connected IoT connectivity provider is limited by mobile network operators (MNOs) themselves. An MNO tends to build towers where lots of people will use them. That doesn’t help in low-population regions or far out at sea. In fact, cellular networks are also called terrestrial networks, because they’re bound to land.Contrast that technology with&nbsp;non-terrestrial networks, or NTNs. These satellite-based connectivity networks fill the coverage gaps left by MNOs. The trouble is, until recently, satellite connectivity required different hardware than its cellular counterpart. It was expensive and space-inefficient to offer both cellular and satellite connectivity in the same device.The solution is a connectivity partner that offers integrated satellite NTN with traditional terrestrial networks—all through the same SIM card.&nbsp;<h2>How to Add Satellite NTN to Your Connectivity Plan</h2>First, look for a connectivity-as-a-service provider that offers seamless satellite NTN within existing cellular plans. Just know that not all your choices offer the same benefits. Choose a connectivity partner that provides the following features in its NTN-integrated service:<ul><li>Automatic network switches.&nbsp;You can’t manage every device’s connection manually. Look for a SIM that automatically connects to the correct cellular or satellite network—and a self-service platform that allows you to define which networks are correct.</li><li>Simple tools for integration with your existing technology stack. You shouldn’t have to hire a team of developers to bring satellites into your connectivity portfolio. Choose a partner that ships ready-to-use APIs for quick, low-stress integration.</li><li>Compatibility with 3GPP low-power, wide area network (LPWAN) technologies. You shouldn’t have to sacrifice access to cellular technologies optimized for IoT just to incorporate your NTN. A specification like NB-IoT gives advantages like a small form factor and limited price; choose a connectivity source that bundles NB-IoT or other IoT LPWAN with satellite coverage.</li><li>Pay-as-you-go connectivity. Price has long been the key barrier to satellite IoT. With a pay-as-you-go model, you don’t pay for the satellite data you don’t use—and you can access satellite networks for as little as $1.00 per kilobyte.</li><li>A combined NTN/cellular SIM card. The other price challenge associated with satellite IoT is the module, which can easily run several thousand dollars per unit. With the right connectivity partner, you can access NTN&nbsp;and global cellular networks with the same SIM card.</li></ul>&nbsp;Satellite integration is becoming increasingly more accessible for IoT developers, and the simplest way to access this technology is to find the right partner. This industry development will help fill connectivity gaps for global deployments—and might be the key to transformative new use cases for mobile IoT in general. Every IoT developer should be aware of this powerful tool in the connectivity toolkit.

For some IoT products, connectivity failure is a momentary inconvenience. For others, it’s a disaster.

Harvesting the Future: IoT Cultivating Smart Agriculture with Mobile Connectivity and Private 5G Networks

<h2 id="isPasted">What Is a Smart Factory?</h2>A smart factory is a factory that achieves operational process improvements, higher quality, and lower costs based on digital data by connecting processes from design to development, manufacturing, and maintenance in a network. In the manufacturing industry, it refers to automating various processes in a factory to realize product quality and productivity improvements, a reduction in manufacturing costs, a shortening of the commercialization, mass production and delivery periods, and other areas of improvement. In other words, a smart factory is a factory working on digital transformation (DX) that aims to transform the entire business process from design to manufacturing, maintenance, and logistics in addition to improving productivity by automating factory equipment.We introduce here the results of a questionnaire survey* we conducted with people involved in promoting the conversion of regular factories into smart factories in the manufacturing industry in Japan.*About the Questionnaire Survey Organization conducting the survey: Murata Manufacturing Co., Ltd. Survey targets: 11,084 workers in the manufacturing industry in Japan (screening survey) and 500 people working in the manufacturing industry who are involved in converting regular factories into smart factories in their companies (main survey) Survey method: Internet survey Survey period: Three days from January 25 (Wed.) to 27 (Fri.), 2023 *Total figures may not match due to rounding.<h3>State of Progress in Converting Regular Factories into Smart Factories</h3>We learned that over 38% of factories are in the process of converting into smart factories or considering converting into a smart factory in the questionnaire we conducted this time (Fig. 1). We can see a trend for even more companies to convert their regular factories into smart factories in the future.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5NTg1NzUzLWltZzAwMDFfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 1: Situation concerning the conversion of regular factories into smart factoriesMoreover, the most common reason for converting regular factories into smart factories is to improve productivity. The next most common reason is to reduce costs (Fig. 2).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5NjU1OTgxLWltZzAwMDJfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 2: Reasons for converting regular factories into smart factories<h3 id="isPasted">Main Factors Behind Inability to Promote the Conversion of Regular Factories into Smart Factories</h3>On the other hand, the following are given as the main factors behind the inability to promote conversion of regular factories into smart factories: following on from the understanding of top management, the establishment of specialist teams, the acquisition and training of specialist human resources, cooperation with external partners and other human resources and know-how shortage issues (Fig. 3).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5Njg1NDc4LWltZzAwMDNfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 3: Main factors behind inability to promote the conversion of regular factories into smart factoriesIn addition, we learned that even factories working to convert into smart factories are suffering setbacks in terms of data analysis and prediction and data collection and accumulation (Fig. 4).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5NzA2MzM1LWltZzAwMDRfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 4: Steps where setbacks are being suffered in the conversion of regular factories into smart factoriesIt is thought that how to overcome these steps will be the key to promoting the conversion of regular factories into smart factories. We will consider these issues using the example of short stoppages, which are one type of equipment loss that are a major factor adversely affecting the productivity of smart factories, from here onward.<h2>Short Stoppages: Blind Spot in the Conversion of Regular Factories into Smart Factories</h2>Equipment loss arising in each process is a major issue that must be resolved for the conversion of regular factories into smart factories that greatly contributes to improving productivity in factories.The types of equipment loss include stoppage losses resulting from failures, setup changes, jig replacements and startup, defective product losses, speed reduction losses, and short stoppage losses. In particular, short stoppages are called idling losses and are losses included in the time when, in principle, the equipment could be demonstrating its performance (net operating time) (Fig. 5).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5NzI4Nzg2LWltZzAwMDVfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 5: Equipment loss times and types<h3 id="isPasted">Short Stoppages: Unseen Equipment Loss Lurking in Manufacturing Lines</h3>Setup change, jig replacement, and startup losses are planned. In addition, as it takes a long time to recover from failure losses, we keep a record showing the operational status. However, short stoppages occur unexpectedly on the line and workers at the worksite recover from it and resume work in a short time. The shortness of this time until recovery means that a record of these short stoppages is not kept in most cases. Furthermore, even if attempts are made to keep records of short stoppages, there is currently no time to do so because a speedy recovery is sought.If we do not record the time of a short stoppage, the operating rate is calculated without including that time. Accordingly, a difference arises with the actual operating rate. Furthermore, the cause of long equipment stoppages such as failure losses may be lurking in short stoppages. It is possible to see cases in which problems in the operating rate due to such short stoppages are overlooked even in factories that have been converted into smart factories.<h3>Does Converting Regular Factories into Smart Factories Produce Short Stoppages?</h3>Many industrial robots and automatic machines are installed in the manufacturing lines of smart factories. These comprise precision components. It is not possible to avoid a decline in their precision due to the usage burden and degradation over time. If the precision of these components declines, malfunctions may occur. For example, an industrial robot may fail to grip work or a deviation may arise in the trajectory of a robot arm and it may not be possible to move the part equivalent to the fingers of the robot called the end effector to the correct position. Such malfunctions may cause short stoppages.<h2>Reasons Why Short Stoppages Are Not Eliminated and Countermeasures</h2>Why are short stoppages, which cause various problems in factories in addition to obstructing improvement in productivity, not eliminated? The reason is that in the midst of frequent short stoppages on a daily basis, there is an atmosphere in which manufacturing worksites do not take the situation seriously.The most effective way to prevent such a situation is to calculate and visualize the losses from short stoppages. However, we would need to enter the process, cause, and equipment stoppage time on a worksheet each time such a short stoppage occurs and then aggregate that data to calculate it, which would interfere with production. Moreover, it is difficult to identify the cause of short stoppages by collecting data once a week or once a month.We obtained results from the questionnaire showing that standardization and visualization using digital technologies and optimization of equipment maintenance with sensors and AI are effective ways of resolving such problems in factories which have been successful in promoting their conversion into smart factories (Fig. 6).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5NzUwNzg4LWltZzAwMDZfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 6: Initiatives in promoting the conversion of regular factories into smart factories<h2 id="isPasted">Clues to Reducing Short Stoppages</h2>We need data on the operating status of equipment to reduce short stoppages. For that, we must be able to accurately and quickly record the equipment stoppage times due to the frequent short stoppages and their causes. We introduce here the m-FLIP solution tool that helps to resolve such issues.<h3>What Is m-FLIP?</h3>m-FLIP is a solution that combines Murata Manufacturing’s worksite improvement know-how and IT technologies to maximize the operating rate of manufacturing devices. This solution makes it possible to quantify factors such as operating rate, actual working rate, and equipment stoppages to increase production and achieve optimal maintenance. This greatly contributes to the visualization of problems that are difficult to reveal such as short stoppages.Furthermore, m-FLIP calculates and outputs the operating rate and actual working rate based on data obtained from PLCs made by multiple manufacturers. In addition, it collects workers’ work information through touch-panel PCs. As a result, we can clarify the duration and number of equipment stoppages, which was previously done by guesswork. We are also able to clearly see the main causes of equipment stoppages and the issues that must be resolved (Fig. 7).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5Nzc2NTU0LWltZzAwMDdfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 7: Services provided by m-FLIP<h3 id="isPasted">m-FLIP Utilization Examples</h3>m-FLIP can support the resolution of various issues at manufacturing worksites. We introduce here some typical utilization examples.<h4>Equipment maintenance:</h4>With checks by humans, it is only possible to monitor the operating status temporarily. However, m-FLIP can continuously monitor the operating status of equipment. It is possible to continuously collect data over several months or several years. This allows us to grasp the aging and changes over time of equipment. As a result, it enables maintenance at the optimal timing while minimizing the impact on the operating rate to the greatest possible extent.<h4>Quality control:</h4>For example, it is possible to monitor static electricity generation status based on data from temperature sensors and humidity sensors around the equipment and to output an alert when the set threshold is exceeded. We can utilize this in quality control such as to prevent the outflow of defective products. Moreover, we can also collect data including information on vibrations, current, and voltage. We can then integrate the data we have obtained from multiple sensors and output it as a single piece of information.<h4>Work procedure review, equipment improvement, and personnel allocation optimization:</h4>We can grasp the movements of workers and the operating status of equipment as quantified information. Therefore, we can also utilize it to consider work procedure reviews, equipment improvements, and personnel allocation optimization.<h4>Preparation of reports:</h4>m-FLIP comes with a function to prepare reports that can be used for reporting (Fig. 8). You can display information in charts and tables. It is also possible to input and save comments. You can share the reports you have prepared.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5ODAwNTEwLWltZzAwMDguanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 8: Monthly report screen<h4 id="isPasted">After-sales support by professionals:</h4>After introducing m-FLIP, we can identify issues from the data we have collected and receive suggestions for improvements and other advice from professionals familiar with production technologies, factory technologies, and other technologies.<h2>m-FLIP Introduction Case Study (Example of Ogaki Murata Manufacturing)</h2>We now introduce a case study from Ogaki Murata Manufacturing in which they resolved frequently occurring problems including short stoppages due to tray replacement in the product-washing process and short stoppages due to component adhesion errors with the m-FLIP operating rate improvement solution tool.<h3>Pursuit of the Causes</h3>We intuitively knew that short stoppages were occurring in the tray/rack refilling machine at the manufacturing worksite. However, we were not able to quantify the stoppage time or the number of stops. Accordingly, we collected data on the tray/rack refilling machine and the component adhesion device with m-FLIP. We uncovered the following problems as a result. ・Non-operation due to waiting for tray replacement: 12% ・Non-operation due to adhesion errors: 8%<h3>Improvement 1: Reduction in the Tray Replacement Time</h3>We now display on ANDON the number of trays remaining until the completion of the tray replacement (Fig. 9). We display in ANDON the timing of the tray replacement before the work of refilling the product into the tray is complete. This has meant we have been able to greatly reduce the time spent waiting for tray replacement.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5ODIxMDM5LWltZzAwMDkuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 9: Countdown ANDON that predicts the equipment work completion<h3 id="isPasted">Improvement 2: Resolution of Short Stoppages</h3>We analyzed in detail the contents of the short stoppages. As a result, we ascertained that 80% or more of the short stoppages were component adhesion errors (Fig. 10 and Fig. 11).<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5ODQyMjMyLWltZzAwMTBfZW4ucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Fig. 10: Breakdown of the equipment operating rate and non-operating rate items<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEwMTI5ODU2NjE4LWltZzAwMTBhLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib">Fig. 11: Operating status Gantt chartWe found that the cause of the component adhesion errors was changes in the clearance between the product adhesion nozzle and product due to changes over time in the washing rack jig. As a countermeasure, we shortened the gap between the adhesion nozzle and the product. This allowed us to significantly reduce short stoppages due to adhesion errors.In this way, it is first necessary to digitize the operating status of equipment and the behavior of workers to improve short stoppages. We can pursue the causes of short stoppages by analyzing and parsing the data we collect.<h2>Summary</h2>This questionnaire revealed issues in the conversion of regular factories into smart factories and challenges in promoting that in numerical data. We can see that quantifying and visualizing the various losses lurking in production lines is essential for improving productivity from these results. We focused on the theme of short stoppages this time. However, quantified data is also indispensable to resolve other issues in the conversion of regular factories into smart factories. The questionnaire results show that this requires high density and quality of the data to be collected as well as analytical skills.<hr id="isPasted"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1711016095493-1711016095493.png" class="fr-fic fr-dii">If you have any questions based on this article that you would like to discuss with an expert at Murata, don't hesitate to reach out.
