Abstract

The invention relates to a WSN mine safety monitoring system with a recombination function and a downhole accident monitoring method, belonging to a mining safety monitoring technology. The invention overcomes the problems of the previous wired monitoring system such as complicated wiring, failure to dynamically follow up an excavating surface, easy damage and the like. In the invention, a ground monitoring center of the monitoring system is an Ethernet system composed of a downhole monitoring access mainframe, a database server, a monitoring terminal and a remote terminal; a downhole wired sensor network is a CAN bus network composed of a plurality of wired sensors; the CAN bus network is connected with the downhole monitoring access mainframe; and a downhole wireless sensor network is composed of gateway nodes, a plurality of cluster-head nodes, a plurality of wireless sensor nodes and a plurality of movable nodes, wherein, the gateway nodes are connected with a CAN bus of the downhole wired sensor network. In addition, after a fault occurs, the gateway nodes and wired sensor nodes can form a higher-level wireless communication network so as to guarantee communication reliability. The invention is applicable to various mines.

Description

technical field [0001] The invention relates to a WSN-based underground mine safety monitoring system and method with a recombination function, relates to an underground mine rescue auxiliary system, and belongs to the technical field of mining safety monitoring. technical field [0002] Type the technical field description paragraph here. Background technique [0003] China is rich in mineral resources, but the natural conditions of the mines are very complex, and the mining conditions are extremely changeable, which increases the unsafe factor of mineral mining, easily leads to major safety accidents, and causes great difficulties for safe production. Taking coal mines as an example, the main causes of mine disasters are gas explosions, coal dust explosions, gas outbursts, water seepage accidents, mine fires, roof collapses, etc. Among the coal mine accidents where more than 10 people died at one time, gas accidents accounted for 71%. much higher than other types of acc...
