Industrial Ethernet switchboard

Abstract

The present invention discloses an industrial Ethernet switchboard, which can be applied to the fields of digitalized transformer substation, industry, military and transportation. The industrial Ethernet switchboard comprises: a housing, a power supply module, a plug-in module, a cascade plug-in module, a self-healing ring network module, a PHY module, an MAC chip module, a central processor unit module, an Atmega128 module, a CPLD module, a FLASH and so on. The present invention is an industrial Ethernet switchboard specifically designed for the environment of electric power automation and digitalisation transformer substation, possesses strong ability of resisting electromagnetic interference, excellent exchange performance due to an exchanging framework without obstruction, strong management storage capacity and intelligent management maintenance. When physical connection fault (N-1) occurs, protection switching can prevent the loss data packet, and ensure that the time-delay for communication recovery is 0. Thus, the invention can reduce manual operation, manual fault and operation costs. Moreover, the invention can fully satisfy the tough requirements on electric power environment and transportation environment, and can be also applied to digitalized transformer substation network, transportation monitor network and the like.

Description

technical field [0001] The invention relates to a communication network device, in particular to an industrial Ethernet switch. Background technique [0002] With the development of power system information technology, IEC61850 has emerged as the only international substation network communication standard. More and more people are focusing on the research and development of "digital substations" and "digital grids". Industrial communication and control platforms occupy an important position. Among them, embedded communication management machine and industrial Ethernet switch are the most representative products. [0003] The power industry, especially the substation environment, has very strict requirements on the reliability and security of digital network communications. According to the requirements of the IEC61850 standard, industrial Ethernet switch products must at least meet the four major requirements of functional requirements, electromagnetic compatibility design...

AI Technical Summary

Problems solved by technology

[0004] Most of the current industrial Ethernet switches have the following deficiencies: first, the ability to resist electromagnetic interference is not strong, and some have a certain ability to resist electromagnetic interference, but not very strong; second, the performance is poor, and many cannot reach the line The third is that the network is limited by the number of switches; the fourth is that in the case of physical connection failure (N-1), the protection switching will cause the loss of data packets, and the communication recovery delay is too large; the fifth is that the management storage capacity is insufficient
