Foreword: In order to effectively extend the data transmission distance and solve the problems of electromagnetic radiation, electromagnetic interference prevention, non-common ground between point-to-point devices, lightning strike resistance and channel resource sharing when transmitting data through cables, the multi-protocol serial communication controller Intel82530 and single-fiber

In recent years, with the development and popularization of the Internet of Things, private network Internet of Things (P-IoT) technology has gradually developed in response to the needs of industry users. First, a brief introduction to the technical system and key performance of P-IoT is

Introduction: In order to fully meet people’s growing material needs, smart water meters have gradually replaced non-smart water meters. In the application process of smart water meters, the RS485 bus is widely used. The bus structure is simple to apply and the cost is low,

Problems faced by petrochemical plants IoT applications in petrochemical scenarios generally have the following characteristics: (1) Most of them are located in urban areas, and the radio electromagnetic environment is complex, requiring high reliability of the system; (2) There are a large number of IoT

1 channel analog collector Our company currently (2020-11-18) has a total of 3 1-channel analog collector products, which can be used in industries such as remote meter reading, intelligent street light supervision, smart fire protection, and automatic monitoring of water plants. The product has complete

In this type of scenario, the environment is generally difficult, the facilities are simple, and the manpower for inspection and monitoring is relatively insufficient. Many accidents, such as forest fires, cannot be discovered and dealt with in time. There is an urgent need for unattended

1 Overview of Internet of Things 1.1 Definition of Internet of Things The Internet of Things (IoT) is an information carrier such as the Internet and traditional telecommunications networks, which allows all ordinary objects that can perform independent functions to achieve interconnection and interoperability .

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
