Wireless network switch system suitable for underground coal mine or coal mine shaft

Abstract

The invention provides a wireless network switch system which is suitable for underground coal mine or coal mine shaft. The wireless network switch system is characterized by adopting designs based on an explosive gaseous environment electric equipment general requirement GB3836.1-2000 and an intrinsic safety requirement GB3836.4-2000; based on high reliability and security of networking operation, adopting a modularized design and international brand industrial-grade chips, adopting electric control components which are all mature and reliable products and suitable for serious working environment of the coal mine underground, and adopting low power consumption design and an external power supply. The wireless network switch system has the advantages that the underground coal mine or coal mine shaft communication technology is improved, the full coverage of the underground coal mine or coal mine shaft network is realized, the defects of a wired network are remedied, the remote monitoring and control for coal mine integrated excavated working face electromechanical equipment and other underground coal mine or coal mine shaft motion equipment are realized, and reliable data are provided for realizing coal extractor high-efficiency automated mining, remote operation and control and fault diagnosis.

Description

technical field [0001] The invention relates to a network communication device, in particular to a wireless network exchange system suitable for underground coal mines. Background technique [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 our country have established industrial Ethernet for the monitoring of underground coal mining equipment and underground environmental parameters. But it mainly adopts the wired network mode (optical fiber + explosion-proof switch). The core components of explosion-proof switches used in underground mines in my country are mainly Hessman and Siemens switches, 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 followi...

AI Technical Summary

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
