Underground coal mine personnel supervision system

Abstract

The invention discloses an underground coal mine personnel supervision system comprising a plurality of underground personnel supervision devices respectively installed at safety helmets of the work personnel entering the underground coal mine, a mine mouth monitoring slave unit arranged at the mine mouth, and an upper monitoring master unit arranged in a ground monitoring chamber. The mine mouth monitoring slave unit and the upper monitoring master unit carry out two-way communication by a local area network; and the plurality of underground personnel supervision devices and the mine mouth monitoring slave unit carry out two-way communication by a wireless communication way. The underground personnel supervision devices include electronic circuit boards arranged at the safety helmets, RFID tags pasted at the outer sides of the safety helmets, and supervision starting switches installed at the outer side walls of the safety helmets. The system has the advantages of reasonable structure design, simple and convenient usage and operation, high intelligent degree, compressive functions, and good using effect. And the number of the underground coal mine personnel in the current state, in and out time of the underground coal mine personnel, specific locations of the personnel at the underground coal mine, current physical conditions of the personnel and the like can be effectively monitored.

Description

technical field [0001] The invention relates to a supervision system, in particular to a coal mine underground personnel supervision system. Background technique [0002] In recent years, my country's coal mine safety accidents have occurred frequently, resulting in heavy casualties and huge economic losses. The problem of coal mine safety production has attracted the attention of all walks of life. When a coal mine safety accident occurs, the on-site environment is complex and harsh, full of unknown and uncertain factors, which seriously threatens the life safety of search and rescue personnel and brings severe challenges to the deployment and implementation of search and rescue work. Therefore, in the process of coal mine production, if the number of coal mine personnel, the work items they are engaged in, their actual location, and current physical condition can be effectively monitored, the search and rescue area can be quickly locked after a coal mine safety accident oc...

AI Technical Summary

Problems solved by technology

However, in the production process of coal mines nowadays, it is generally only simple statistics on the number of personnel entering the coal mine and the identity of each entering personnel

Therefore, there is currently a lack of a coal mine underground personnel supervision system with reasonable circuit design, convenient installation and layout, easy operation, high intelligence, and good use effect, which can monitor the number of underground personnel in the coal mine under the current state and the time of entry and exit of each staff member. , Effectively monitor the specific location and current physical condition of the coal mine
