WHAT IS The most common data type used in Industrial Internet of Things (IIoT) applications?4 answersThe most common data type used in Industrial Internet of Things (IIoT) applications is stream data. Stream data is generated in IIoT applications and presents new characteristics such as a huge amount of data, ultrahigh computational complexity, and large memory consumption. It is difficult for current mainstream methods to effectively cope with these problems. To address these challenges, an efficient Gaussian kernel microcluster real-time-clustering method for IIoT data streams (GKMC) has been proposed. This method uses a microcluster sketch structure to participate in clustering directly, solving the problem of limited memory storage. It also uses a Gaussian kernel function to calculate the local density of microclusters, enhancing the detection of anomalies. The GKMC method has been shown to have a better clustering effect than current mainstream stream clustering algorithms.
How can STM32L072 MCU be used for smart-grid monitoring?4 answersThe STM32L072 MCU can be used for smart-grid monitoring by implementing a system that synchronizes event counts using one-time passwords. This system initializes an error count, receives a seed value and event count from the MCU, calculates a monitoring key value using a hash function, and compares it with the key value received from the MCU to determine the operation state. Additionally, the STM32L072 MCU can be used as a gateway processor to connect the independent working monitor unit of an electric network to the Ethernet. This allows for the transmission of monitoring data to a control center, updating of server machine data, and display of timely data on a network page. The MCU can also be used to transmit commands to the network MCU for compensating reactive power by connecting relays to the electric network.
What is the best way to use an Arduino microcontroller for remote control?5 answersThe best way to use an Arduino microcontroller for remote control is by utilizing it with various communication systems such as the internet network, SMS (Short Message Service), and GSM (Global System for Mobile Communication) network. Arduino can be used to control electric motor starting, electric lights, environmental variables, and security systems. It can also be integrated with smartphones and wireless technologies to provide user-friendly interfaces for controlling and monitoring power consumption patterns of home appliances remotely. Bylink and RF Remote modules are examples of tools that can be used to control Arduino-based systems.
How IIoT devices interact with PLCs for data collection?4 answersIIoT devices interact with PLCs for data collection by integrating communication technologies and databases with automation. PLC control devices are widely used in industry and can communicate with popular database management systems like SQL Server. General PLCs have gained the ability to process large amounts of industrial data and share the workload of cloud servers, transforming them into edge-PLCs. Machine data acquisition plays a role in bringing factory floor data into the IIoT environment, which can be visualized in real-time through AR and MR-based smart devices. Network communication in Industrial Control Systems (ICSs) is often implemented via an IP-based protocol, allowing IIoT devices like PLCs to communicate and acquire data. A dual Microcontroller Unit (MCU) setup can ensure resilient controlling for IIoT devices like PLCs, providing a possible solution for secure architectures in the IIoT.
What are the different IoT data collection solutions available?5 answersThere are several different IoT data collection solutions available. One approach is to use unmanned aerial vehicles (UAVs) as a platform for gathering data from IoT devices located worldwide. Another solution involves a wireless-powered IoT network that uses a hybrid access point (HAP) to charge devices and facilitate backscattering transmissions. Additionally, integrating homomorphic encryption (HE) algorithms into sensor devices allows for encrypted data transmission in wireless sensor networks. Mobile data collection can also be enhanced by using a learning-based approach for trajectory planning, where a deep Q-learning network (DQN) is trained to maximize data collection and reduce energy consumption. Finally, a method of water data collection can be achieved through the coordination of an unmanned surface vehicle (USV) carrying UAVs, with a heuristic algorithm used to optimize data collection and energy consumption.
