Description

technical field

[0001] The invention relates to the field of mine and functional underground safety monitoring and wireless communication, in particular to a sensor network-based underground safety monitoring system, device and method. Background technique

[0002] At present, safety work in coal mines is one of the most important tasks in the process of coal mining. The production conditions of coal mines are very harsh, and major accidents are basically gas explosions and gas outbursts. , carbon monoxide, carbon dioxide and other harmful gases as well as parameters such as temperature, wind speed, start and stop status of key equipment are monitored. For high-gas mines, mine safety monitoring equipment must be installed. For mines that are not equipped with mine safety monitoring systems, the coal roadways, half-coal rock roadways, and the excavation face of rock roadways with gas gushing, and the excavation of rock roadways without gas gushing The working face and the co...

Embodiment Construction

[0018] like figure 1 As shown, a complete set of underground wireless safety monitoring system is established, including the following parts: ground monitoring base station (1), roadway base station (2), wireless node (3), wireless mobile terminal, and the main control computer of the ground system through The ground monitoring base station (1) receives mine data information transmitted by the roadway base station (2), and the roadway base station (2) is responsible for collecting data information of surrounding wireless nodes (3).

[0019] The functions realized by the downhole wireless safety monitoring system include: real-time monitoring of various downhole environmental parameters such as gas, carbon monoxide, carbon dioxide, temperature, wind speed and other parameters. If the environmental parameters exceed the standard, the control of related equipment will be automatically shut down; (3) Realize the positioning of mine staff, voice communication between ground monitor...
