Abstract

The invention discloses an eight-serial-port server supporting more than hundred connection sessions. The server comprises a serial port module and an Ethernet module; the serial port module and the Ethernet module are both connected to a microcontroller, so that the conversion and transmission of serial port signals and network signals can be realized; a serial port isolation protection module isfurther arranged between the serial port module and the microcontroller, so that serial port data can be subjected to isolation protection through the serial port isolation protection module; the serial port module comprises eight terminals and a serial port expansion module; and one end of the serial port expansion module is connected to the microcontroller, and the other end of the serial portexpansion module is connected with the eight terminals in a one-to-one correspondence mode through the serial port isolation protection module. The eight-serial-port server supporting the more than hundred connection sessions solves the problem that isolation protection of terminal type serial ports cannot be realized in the prior art.

Description

technical field [0001] The invention relates to the server field, in particular to an eight serial port server supporting more than one hundred connection sessions. Background technique [0002] The serial port server provides the serial port to network function, which can convert the RS-232 / 485 / 422 serial port into a TCP / IP network interface, and realize the two-way transparent transmission of data between the RS-232 / 485 / 422 serial port and the TCP / IP network interface. The serial device can immediately have the TCP / IP network interface function, connect to the network for data communication, and greatly expand the communication distance of the serial device. [0003] The serial port server at the present stage cannot realize the isolation protection of the terminal type serial port, and it is necessary to design a serial port server that supports more than one hundred connection sessions. Contents of the invention [0004] The purpose of the present invention is to prov...
