Industrial routers are communication equipment that realizes outdoor networking based on cellular networks. 5G industrial routers are outdoor communication equipment that are realized through 5G networks. They are 20 times faster than 4G industrial routers. The price and speed are directly proportional. The current market

Friends who have used PLC should know that the communication between PLC and control equipment is basically based on the serial communication interface and is controlled using its corresponding communication protocol. The serial communication interface includes RS232, RS422, and RS485. , RS422 can be seen

Ethernet is the most common communication protocol standard used in existing local area networks today. This standard defines the cable types and signal processing methods used in LAN). Ethernet transmits information packets between interconnected devices at a rate of 10~100Mps. Ethernet using twisted pair cable

1. Application of serial port server in the Ministry of Transport 1.1 Equipment distribution and connection status The Meishan Iron and Steel Transportation Department has 5 sets of AEI equipment distributed at the Guxiong Railway Station, which is far away from the transportation information system

Traditional PLC uses ladder diagrams and statement lists to make programming easy, and has the advantages of short system software development cycle and on-site debugging of programs. Traditional PLCs also have the disadvantages of being unable to support communication interfaces such as I2C and SPI

Existing industrial routers are generally used in relatively harsh environments. Due to work needs, most of the time the router needs to run all day or for several months. In order to make the industrial router have a longer service life, the existing router. Features

Serial communication method 2.1 Full-duplex and half-duplex modes If a data communication system uses different paths for the two transmission directions of data, such a system can work in full-duplex mode, and a system using full-duplex mode can send and receive at the same time.

4G data transmission module The 4G data transmission module developed by Zongheng Intelligent Control is a shell-type data transmission terminal. There are two products for users to choose: rail type and ear-mounted type, which can meet different application scenarios. This product is developed to realize

In process control projects, communication problems between DCS and lower computer PLC or field instruments are often encountered. Many chemical plants now adopt a general contract plus subcontracting model when constructing. Each supplier provides its own control system (usually mostly PLC), but in the central

The collection and transmission module developed by Zongheng Intelligent Control mainly uses 4G network as the transmission channel, which can realize the mutual transmission of data between serial devices and network servers through the operator’s network. Currently, it can be roughly divided into two categories

The serial port server mainly includes: a power circuit module, an ARM9 processor, a network port circuit module, and a serial port circuit module. The ARM9 processor includes the following interfaces: at least one network port circuit interface and at least one serial port circuit

Different from Internet thinking, fragmentation is the best opportunity for the Internet of Things. By connecting things within a limited range and a short time window, you seize the fleeting opportunity. Most of the companies that practice this principle have achieved good results, and we
