Double-Ethernet networking server provided with multi-serial ports

Abstract

A double-Ethernet networking server provided with multi-serial ports comprises a power module, a processing module, an Ethernet module, a serial port module, a communication indication module and an EMC (electromagnetic compatibility) module, wherein the power module is connected with the processing module, the serial port module and the Ethernet module respectively and supplies power to the processing module, the serial module and the Ethernet module; the serial port module, the Ethernet module and the communication indication module are connected with the processing module respectively; the EMC module comprises a lightning protection part and an electromagnetic isolation part; the lightning protection part is directly connected with the serial port module and the Ethernet module respectively; the electromagnetic isolation part is connected among the serial port module, the Ethernet module and the processing module; the Ethernet module is provided with more than two Ethernet interfaces to form main and standby networks; and the serial port module comprises basic serial ports and extension serial ports. According to the double-Ethernet networking server, multichannel serial port equipment can be connected to the network, and the server supports connection of double networks of a host and a standby computer of a background system and can finish transparent transmission of data between the serial ports and the Ethernet interfaces simultaneously.

Description

technical field [0001] The invention relates to the field of distribution network automation, in particular to a server for realizing networking of a large number of serial devices. Background technique [0002] Distribution network automation refers to the use of modern electronics, computers, communications and network technologies to integrate online and offline data, distribution network data and user data, power grid structure and geographic graphics to form a complete automation system. The modernization of monitoring, protection, control, power consumption and distribution management of distribution network and its equipment in normal operation and accident state. A key technical issue of distribution network automation is how to form a network between IEDs (Intelligent Electronic Devices) in the distribution network and remote dispatch centers through appropriate communication methods. [0003] In the early days of distribution network automation, the communication ...
