The Internet of Things supported by the fifth-generation mobile communication system (5G system for short) will expand its access volume and coverage, and can greatly better adapt to and meet the growing operation and maintenance needs of urban rail transit. By studying the development direction,

Released in 1962 by the Electronic Industries Association (EIA) and BELL and other companies; the full name of the RS 232C standard (protocol) is the EIA-RS-232C standard, where EIA represents the Electronic Industries Association, RS represents the recommended standard , and 232 is the identification

In the context of the rapid development of science and technology, wireless information technology has brought more convenience to people’s lives, and 5G wireless communication technology is also constantly developing and maturing, and will replace the current network in the future. Based on this, this

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

A Beidou/GPS positioning module solution with independent intellectual property rights chips as the core is proposed. It uses a highly integrated radio frequency chip and a low-power navigation baseband processor. It can receive Beidou and GPS signals at the same time to achieve high -precision

RS-422 RS-422 (EIARS-422-AStandard) is the serial port connection standard for Apple’s Mac in osh computers. RS-422 is developed from RS-232 and is proposed to make up for the shortcomings of RS-232. RS 422 is a one-way, balanced transmission method for single-machine transmission and multi-machine reception.
