Geological disaster rescue scenarios refer to extremely severe scenarios caused by geological environmental disasters that are sudden and destructive, such as earthquakes, mudslides, landslides, etc. In such scenarios, communication infrastructure is usually damaged or even destroyed, and the original communication network faces the risk of

4-channel analog collector Provides 4-channel AI (analog input) interface, which can be used to collect various sensor data, such as temperature sensor, water pressure sensor, wind direction sensor, etc. It is often used in automatic monitoring of pool water levels, smart construction site dust monitoring

The Internet of Everything is the definition of the Internet of Things and the ultimate essence of Internet of Things applications. However, at present, more mature IoT applications are still concentrated on a single IoT solution, and there is still a lack of information sharing

Introduction to LoRa LoRa is an ultra-long-distance, low-power IoT solution provided by Semtech. Semtech and many industry-leading companies, such as Cisco, IBM and Microchip, initiated the LoRa (Long Range, Wide Range) Alliance and are committed to promoting its alliance standard LoRaWAN technology to meet various

Preface: Analyzing the current status of the rapidly developing Internet of Things technology, in view of the explosive big data growth brought about by the Internet and the Internet of Things everywhere, combined with the widespread application of artificial intelligence technology, the concept of the

Abstract: In view of the shortage of fresh vegetables in the island border areas and barren areas along the “One Belt and One Road”, combined with agricultural planting theory and experience, using Internet of Things technology to analyze the environmental factors required for each link

With the development of industrial automation, remote meter reading has become an important part of the smart grid system. Nowadays, people’s requirements for power supply continue to increase, and data obtained by remote meter reading has gradually replaced the early manual meter reading. Traditional manual

Abstract: In order to solve the problem of line selection and location of small current ground faults in the distribution network, this paper analyzes the adaptive filtering properties of the EMD algorithm. The IMF decomposed by EMD of the small current ground fault current displays

Introduction to the paper: As people’s requirements for power quality are getting higher and higher, the power supply reliability of distribution networks has received great attention. The distribution terminal DTU of the switching station is an important part of the distribution network system. The remote

The distribution automation terminal is the execution unit of the distribution automation system and an important part of the distribution automation system. It mainly monitors and controls the switching equipment in the distribution system and has functions such as fault location and isolation, system protection,

In the Internet of Things, short-distance wireless communication technology is constantly developing and innovating. Short-distance wireless communication technology is mainly divided into two categories. One is LPWAN (low-power Wide-Area Network, low-power wide area network), which is often called Wide area network communications technology. The other

The proposal of distribution automation has led to rapid development of the power market. It integrates modern communication technology, computer technology, automatic control technology and other technologies to realize the monitoring, management and control of the distribution system. The distribution automation system uses distribution automation
