Double-network eight-serial port server with terminals

Abstract

The invention discloses a double-network eight-serial port server with terminals. The server comprises a shell, a main controller, a serial port expansion circuit, serial port processing circuits, a network processing circuit and network interface circuits, wherein the main controller, the serial port expansion circuit, the serial port processing circuits, the network processing circuit and the network interface circuits are respectively arranged in the shell; the serial port expansion circuit and the network processing circuit are respectively connected with the main controller; the serial port expansion circuit is connected with at least eight serial port processing circuit; the network interface circuits are respectively connected with the network processing circuit; a CPLD control circuit is connected between the serial port expansion circuit and the main controller; a plurality of connection terminals are arranged on the side surface of the shell; a baffle plate is hinged on the side surface, where the connection terminals are arranged, of the shell; the baffle plate is located above the connection terminals; and the baffle plate can lean against the connection terminals. The double-network eight-serial port server is capable of overcoming the problems that the transmission efficiency is low and the shell of the serial port server is single in function as the serial port server in the prior art is bad in anti-interference ability and a plurality of serial ports cannot be well transmitted in parallel.

Description

technical field [0001] The invention relates to the field of serial port servers, in particular to a dual-network eight serial port server with terminals. 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 inter...
