Precise personnel-limiting explosion-proof control device for mine mining area

Abstract

The invention discloses a precise personnel-limiting explosion-proof control device for a mine excavation area. The device includes an underground industrial Ethernet ring network platform, a 10-gigabit industrial Ethernet switch, a mining intrinsic safety type personnel accurate positioning core data interaction server, a mining explosion-proof and intrinsic safety type display controller, a mining intrinsic safety type personnel positioning card reader substation, a mining intrinsic safety type access controller, a mining intrinsic safety type audible and visual alarm and an access control part, wherein the underground industrial Ethernet ring network platform is formed by building a plurality of 10-gigabit industrial Ethernet switches. According to the mining intrinsic safety type personnel accurate positioning core data interaction server, the number of personnel in a production area is automatically read and identified, the number of the personnel in the production area is judged in real time, comparison operation is automatically completed, related execution information is generated, the mining intrinsic safety type access controller is connected, and therefore accurate control over the personnel in the production area is achieved; besides, related production area access control parts are arranged on a driving working face and a coal mining working face.

Description

technical field [0001] The invention relates to the field of mining, in particular to an anti-explosion control device for precise limited personnel in a mine excavation area. Background technique [0002] my country is the world's largest coal-producing country, with nearly 30,000 coal mines, including more than 500 large and medium-sized coal mines, more than 20,000 small coal mines, and more than 1 million underground workers. When analyzing the major accidents that occurred in several coal mines recently, it was found that the main reason was that the information communication between ground and underground personnel was not timely, so that it was difficult for ground personnel to grasp the distribution and operation conditions of underground personnel in a timely and dynamic manner, and it was difficult to accurately locate personnel. If the location of the underground personnel can be determined early, it will bring great convenience to the rescue work, save a lot of t...

AI Technical Summary

Problems solved by technology

Although the number of personnel entering the well in a single shift in the mine is controlled within the limit, but in the process of underground shift handover, it is easy to have the problem of local personnel exceeding the limit in the mining face, resulting in short-term overcrowding in some areas, which is likely to cause distortion of uploaded data or alarm data
