High-density network monitoring and early warning system for mine coal spontaneous combustion characteristic information

Abstract

The invention provides a mine coal spontaneous combustion characteristic information high-density networking monitoring and early warning system. The system comprises multi-parameter wireless sensor nodes and wireless monitoring base stations. According to each multi-parameter wireless sensor node, an infrared remote control module, a micro negative pressure pump module, a 485 module and a sound-light alarm module are all connected with a first single chip microcomputer; the first single chip microcomputer is in communication connection with a first wireless ad hoc network module; the first wireless ad hoc network module is connected with the corresponding wireless monitoring base station. As for each wireless monitoring base station, a second wireless ad hoc network module is connected with a second single chip microcomputer, a touch screen, a data storage module, the 485 module and a RJ45 module are all connected with the second single chip microcomputer, the second wireless ad hoc network module is in communication connection with a looped network switch, and the looped network switch uploads transmission information to a ground monitoring center through a communication cable. Through the monitoring and early warning system, mine coal spontaneous combustion hidden danger can be effectively and early predicted and positioned, and hazards caused by coal spontaneous combustion to mine production are avoided.

Description

technical field [0001] The invention relates to a mine safety monitoring and monitoring system, in particular to a high-density networked monitoring and early warning system for mine coal spontaneous combustion characteristic information. Background technique [0002] The current situation of coal mine production in my country is as follows: the depth of mine mining is developed, the stress of surrounding rock is large, there is a lot of coal left in fully mechanized caving, the law of air leakage is complex and changeable, and the risk of spontaneous combustion is large; Strong air leakage, a large amount of loose coal remains in the adjacent section, which is easy to oxidize and heat up. The mined-out areas formed by mining are gradually connected together, and there are serious impacts, gas, poisonous and harmful gases gushing out, and coal spontaneous combustion hazards in large-scale gobs. Especially after the production of some mining areas of the mine ends and is clos...
