Multi-protocol Ethernet switch for mines

Abstract

The invention relates to a multi-protocol Ethernet switch for mines and belongs to comprehensive network communication equipment for mines. In the multi-protocol Ethernet switch provided by the invention, a core processing module is simultaneously connected with a first program storage module, a second program storage module, a data storage module and an Ethernet data transformation module, wherein the Ethernet data transformation module is simultaneously connected with a serial port communication module, an optical port communication module and an Ethernet module; the Ethernet module comprises a network filter and a port; the port is connected with the Ethernet data transformation module through the network filter; a power supply module is connected with all the modules and provides energy sources for each module; the power supply module comprises a first power supply regulator, a second power supply regulator and a third power supply regulator; the second power supply regulator is connected with the third power supply regulator in series; and the second power supply regulator and the third power supply regulator which are connected in series are connected with the first power supply regulator in parallel. The multi-protocol Ethernet switch provided by the invention has the advantages that the access of multiple types of equipment is realized; and reliable data sources are provided for the high-efficiency automated mining of coal mines and the remote supervision and fault diagnosis of coal mine equipment.

Description

technical field

[0001] The invention relates to a comprehensive network communication device for mining, in particular to a multi-protocol Ethernet ring network switch for mining. technical background

[0002] The comprehensive mine automation platform is vigorously promoted and widely used. It is an important guarantee for the safe and efficient production of coal mines, and the communication network platform is the basis of mine comprehensive automation. At present, most coal mines have their own industrial Ethernet to realize the communication between coal mine equipment, personnel and centralized control center, and the Ethernet switch is an important part of the communication system. Once a failure occurs, it will not only affect the safety of the coal mine, but also Bring immeasurable loss to coal mine production. Most of the switches on the market are aimed at general application environments, lack necessary protective measures, and do not form a ring network to ensu...
