Environment gas remote sensing equipment for mine after disaster

Abstract

The invention discloses environment gas remote sensing equipment for a mine after disaster. The equipment is mainly applied to underground rescue after disaster and can be carried along with a person. The equipment mainly comprises a laser transmitter, a laser receiver, a control processing unit, a display screen, a communication interface, a temperature remote sensing monitoring unit and a visible laser transmitter; the equipment adopts an open air chamber and can conduct remote sensing monitoring on multiple gas concentrations in the environment and the environment temperature. For accidents such as underground gas explosion and fire disaster, a large amount of poisonous and harmful gas can be generated, and a large amount of oxygen is consumed; by means of the equipment, searchers and ambulancemen can know various gas concentrations and environment temperature of the region which is not yet reached in advance after the disaster of the mine, effective measures are adopted in advance, the searchers and ambulancemen are prevented from being hurt by the large amount of poisonous gas generated by the accidents such as gas explosion and the fire disaster, life of rescuers is protected, and the rescue efficiency is improved.

Description

technical field [0001] The invention relates to remote sensing equipment for ambient gas after a mine disaster, and the equipment relates to the fields of 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. After the accident, it is the key to correct and effective rescue and reduce casualties to grasp the situation of the underground accident scene in time. Accidents such as underground gas explosions and fires will produce a large amount of CO, CO 2 , CH 4 and other toxic and harmful gases consume a large amount of O 2 . When the concentration of toxic and harmful gases at the accident site is extremely high, O 2 When the content is low, it will endanger the lives of search and ...

AI Technical Summary

Problems solved by technology

The short-distance remote sensing monitoring applied to mines can only detect methane concentration at present, and cannot detect other gas concentrations and ambient temperatures, and the general detection distance does not exceed 30 meters; the detection rod detection is to fix the methane sensor on the probe rod At the top, extend the probe rod to the unreached area for detection. This method is limited by the length of the probe rod, and the detection efficiency is low, which affects the efficiency of rescue work; throwing detection is to throw the methane sensor to the unreached area of ​​the roadway through a special throwing device Area, and then detect the environment, because the operation of throwing equipment is greatly affected by human factors, the sensor damage rate is high, and the success rate of throwing is low. Although the detection distance is higher than that of the probe rod method, the actual application effect is not ideal
