Eight-serial-port server with DTU function

Abstract

The invention discloses an eight-serial-port server with a DTU function. The eight-serial-port server comprises a main controller, an Ethernet module, a wireless network module, a serial port module and a redundant power supply, wherein the Ethernet module, the wireless network module, the serial port module and the redundant power supply are coupled to the main controller, so that mutual conversion and transmission of serial port signals and network signals can be realized; the Ethernet module and the wireless network module are network modules of the serial port server, so that wired and wireless transmission of data is realized; the serial port module comprises a serial port expansion module and a serial port processing circuit; the serial port expansion module comprises eight independent serial interfaces; the serial port processing circuit is coupled to each serial interface; a serial port isolation protection module is coupled to the serial port module so as to realize isolationprotection on the independent serial interfaces in the serial port module; and the main controller uses an S3C2440 chip. The eight-serial port server solves the problems that a serial port server is single in function, unfavorable for remote use, limited in use, poor in anti-interference capability and short in service life in the prior art.

Description

technical field [0001] The invention relates to the field of serial port servers, in particular to an eight serial port server with DTU function. Background technique [0002] With the advancement of technology and the rapid development of Internet of Things technology, more and more bottom-end devices need to be connected to Ethernet to transmit data to the main control room. At the same time, with the rapid development of electronic technology and network communication technology, serial port communication is gradually applied in various fields, and penetrates into many aspects such as telecommunications, electric power, and industrial control. Serial port communication means that the data of the bottom-end equipment is transmitted to the upper computer in a serial manner. Realize the data acquisition, analysis and processing of the bottom-end equipment by the host computer. With various applications, transmission requires more comprehensive and more convenient functions...

AI Technical Summary

Problems solved by technology

[0005] In view of the above technical problems, the purpose of the present invention is to overcome the single function of the serial port server in the prior art, which generally only carries out data transmission through Ethernet, which is not conducive to remote use, and the use is very limited, and the ability of anti-interference is poor, and it is interfered by signals. When it is used, it is easy to cause communication interruption and seriously affect the mission life of the equipment, so as to provide a wireless transmission function during use, which is convenient for users to use remotely, has a wider range of use, and the serial port is not easily interfered by signals.
