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.

Abstract

The invention discloses a multi-parameter mine laneway fire monitoring and alarming system. Mine laneway fires are characterized in that finding is difficult, and the development is rapid; a traditional laneway fire alarming system is long in reaction time, and misstatement and reporting missing are likely to occur, so that the fire behavior cannot be controlled in time, and a large number of losses of life and personal injury are caused. The system mainly comprises an information processing server, an alarming device, a communication network, a gas concentration remote sensing device, a temperature monitoring device and the like; and by means of the system, the characteristic of concentration of gas in the monitoring zone environment can be measured through the gas concentration remote sensing device, analysis of integrated monitoring data such as temperature and smoke can be carried out, and a fire alarm can be given out. By means of the system, laneway fire characteristic gas can be accurately monitored, the alarming accuracy rate is greatly improved, and important guarantees are provided for coal mine safety production.

Description

technical field [0001] The invention relates to a multi-parameter mine roadway fire monitoring and alarm system, which involves the fields of sensor technology, laser technology, spectral 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 tu...
