RJ45 type serial port server with serial port protection function

Abstract

The invention discloses an RJ45 type serial port server with a serial port protection function. The RJ45 type serial port server comprises a master controller, a serial port expansion circuit module, serial port processing circuit modules, a serial port protection circuit, a redundant power source module, a network processing circuit module, an internet access interface circuit module and RJ45 type interfaces. The serial port expansion circuit module, the network processing circuit module and the redundant power source module are coupled with the master controller, the serial port processing circuit modules are connected with the serial port expansion circuit module, each serial port processing circuit module is connected with the corresponding RJ45 type interface, and the serial port protection circuit and the RJ45 type interfaces are connected. According to the RJ45 type serial port server, the problems that in the prior art, a serial port of a serial port communication server is likely to be damaged, and the service life is short are solved.

Description

technical field [0001] The invention relates to the field of serial port servers, in particular to an RJ45 type serial port server with serial port protection. Background technique [0002] With the development of Internet of Things technology, more and more bottom-end devices need to be connected to Ethernet to transmit data to the central control room. At the same time, with the rapid development of electronic technology and network communication technology, data collection and transmission are gradually applied in various fields, and penetrate into many aspects such as telecommunications, electric power, and industrial control. Serial communication servers are widely used in traditional attendance systems, card systems, access control systems, POS consumer systems, medical security systems, industrial control, electric power, telecommunications and other fields. A serial port server is connected to sensors, detectors, card readers or other devices to transmit data as an ...
