Problems solved by technology

The shortcomings of underground wired Ethernet are mainly reflected in the following points: (1) it is arranged in the main roadway and cannot cover the entire underground; (2) it is expensive; (3) it cannot realize the monitoring of moving electromechanical equipment, such as coal shearers and locomotives Wait
At present, my country's coal mine comprehensive automation projects have not covered the fully mechanized mining face, and the remote monitoring of fully mechanized mining equipment cannot be realized

Abstract

The invention relates to an intrinsic safety type wireless switch which is characterized by comprising a core processing module, a program storage module, a data storage module, a PCI bus slot, a wireless transmission module, an Ethernet data switching module, an Ethernet module and a power supply module. The invention has the advantages of improving down-hole communication technology of coal mines, realizing the overall coverage of down-hole networks of the coal mines, making up the defects of wired networks and realizing the remote monitoring and control of electrometrical equipment on comprehensive faces of the coal mines and other down-hole moving equipment of the coal mines, thereby providing reliable data for high-efficiency automated mining, remote manipulating and fault diagnosis of coal mining machines.

Description

1. Technical field [0001] The invention relates to a wireless switch, in particular to an intrinsically safe wireless switch used for transmission of working condition information of electromechanical equipment in coal mines. 2. Background technology [0002] Coal mine comprehensive automation is the guarantee of high yield, high efficiency and safe production in coal mine, and coal mine underground network platform is the basis for realizing coal mine comprehensive automation. At present, many coal mines in my country have established industrial Ethernet for the monitoring of underground coal mining equipment and underground environmental parameters; There are two types of switches of Hessmann and Siemens, and then an explosion-proof casing is added to meet the safety requirements of coal mines. The shortcomings of underground wired Ethernet are mainly reflected in the following points: (1) it is arranged in the main roadway and cannot cover the entire underground; (2) it i...
