Currently, a technological and industrial revolution represented by a new generation of artificial intelligence is brewing. The construction of digital, networked, and intelligent information infrastructure is accelerating. Integrated innovation and cross-field innovation characterized by the cross-fusion of information communications, life , and materials science have

Since the 2010s, many “brain” and “nervous system” concepts have emerged in the field of IT technology, such as Internet brain, Google brain, Baidu brain, 360 security brain, Huawei urban nervous system, etc. City brain is one of them. This is an interesting phenomenon. Why

1 Introduction With the rapid development of science and technology and information technology in our country, advanced technology has been applied to various industries. In modern control systems, data must be unified and analyzed, and equipment must be controlled in real time. Therefore, microcontrollers are

With the rapid development of information technology, the dependence of private information and business information transmission on wireless communication networks is significantly increasing, and the resulting attention to the security issues of the communication system itself is also rapidly increasing. As shown in Figure 1,

With the gradual maturity of network technology and the arrival of the wireless sensor era, wireless sensor network technology has become a technology hotspot in recent years. Embedding a standardized network protocol in network equipment can improve the interconnection between networks, improve the flow between

With the development of network technology, sensor technology, and communication technology, mankind has entered the era of the Internet of Things. In the era of the Internet of Things, a large amount of information, instructions, and data need to be transmitted between devices , which

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

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

1.Contact control signal line: DSR: Data set ready, the data device is ready, indicating that the MODEM is ready for use. DTR: Data Terminal ready, the data terminal is ready, indicating that the data terminal can be used. RTS: Request to send, request to send,

The ZHC492CG developed by Zongheng Intelligent Control is a 4G industrial-grade positioning module that uses Beidou GPS dual-mode positioning. At the same time, this product supports 4 channels of dry (wet) node detection, 4 channels of relay (COM, NO , NC) output, 4 channels of

The Electronic Industries Association (EIA) formulated and released the RS 485 standard in 1983, and it was revised by the Telecommunications Industry Association (TIA) and named TIA/EIA-485-A. Since the proposed standards proposed by EIA are all prefixed with “RS”, in the communications industry, it is
