Monitoring and alarming system for fire of mine tunnels

Abstract

The invention discloses a monitoring and alarming system for a fire of mine tunnels. The fire of the mine tunnels has the characteristics of difficult finding, rapid spreading and the like, and the traditional alarming system for the fire of the tunnels is long in response time and is easy in occurrence of misreport and failed report, so that the fire can not be controlled in time and a large amount of personnel casualties is caused. The system mainly comprises an information processing server, an alarming device, a communication network, a gas concentration remote sensing device, a wind direction monitoring device and the like. The system can monitor the characteristics of gas concentration and the like in the environment of monitored areas by the gas concentration remote sensing device, and can give a fire alarm by comprehensive analysis for monitoring data of the wind direction and the like. The system disclosed by the invention has the advantages that characteristic gases of the fire in the tunnels can be accurately monitored, so that the alarming accuracy is greatly improved and an important guarantee is provided for safety production of coal mines.

Description

technical field [0001] The invention relates to a mine roadway fire monitoring and alarm system, which relates to the fields of sensor technology, laser technology, spectrum analysis technology, signal processing technology and the like. Background technique [0002] Coal is the main energy in my country, accounting for about 70% of the primary energy. The coal industry is a high-risk industry, and accidents such as gas, fire, roof, and coal dust have plagued coal mine safety production. Mine fires in coal mines mainly include gob fires and roadway fires. Mine roadway fires have the characteristics of difficulty in discovery, rapid development, and difficulties in fire fighting and rescue. Once a fire breaks out, if the fire cannot be controlled in time, the scope of the fire will expand rapidly, causing a large number of casualties. Therefore, timely detection of mine roadway fires is of great significance. At present, the fire monitoring methods in mine tunnels mainly u...

AI Technical Summary

Problems solved by technology

At present, the fire monitoring methods in mine tunnels mainly use temperature monitoring and smoke monitoring, etc. Smoke monitoring has the disadvantages of slow response, high false alarm rate and false alarm rate; the current more advanced method of temperature monitoring is to use optical fiber distribution temperature monitoring, but optical fiber is prone to Damage, complicated installation, difficult maintenance, etc.
