Further, the harmful gas sensor arranged at each detection point in the step B comprises a gas sensor.
Further, the harmful gas sensor arranged at each detection point in the step B further comprises a carbon monoxide sensor, a carbon dioxide sensor, a nitrogen dioxide sensor, a hydrogen sulfide sensor and a sulfur dioxide sensor.
Furthermore, each detection point in the step B is also provided with a camera, when a certain detection point detects that harmful gas exists, the processor controls the camera to shoot, and the camera sends the shot harmful gas to the processor.
Further, the camera is an infrared camera.
Further, the warning indication command in step H is a voice prompt.
Further, the processor sends out early warning instruction order and then packs the harmful gas information and the shooting information detected and sends to the cloud for storage.
Furthermore, the distance between every two adjacent detection points is 25-30 meters.
Compared with the prior art, the invention has the following advantages:
the coal mine harmful gas inspection method is characterized in that a harmful gas sensor is arranged at each detection point and used for detecting harmful gas at the detection point, when the harmful gas is detected to exist, detection information is transmitted to a processor, meanwhile, the processor acquires the information of a locator at the detection point and gives an alarm to remind a worker to check and process the information; the method for inspecting the harmful gas in the coal mine is convenient to use, replaces a mode of manually filling detection information, and is more accurate and convenient to look up.
