step three, the wireless multi-channel detection module sends the encoded temperature information and the position information acquired by the gps module to the information processing unit; meanwhile, the wireless infrared imager transmits the acquired data to the information processing unit;
processing the received information by the information processing unit so as to position the fire range of the coal bed;
4.1) the information processing unit corresponds the infrared image aerial-photographed by the wireless infrared imager to the coordinates of the multicolor luminous light source to form a ground surface temperature distribution map;
4.2) the information processing unit decodes the data transmitted by the wireless multi-channel detection module, and the temperature data acquired by the wireless temperature sensor corresponds to the actual space coordinate position transmitted by the gps module to form a space three-dimensional temperature distribution map;
and 4.3) determining whether the detection range of the fire zone needs to be adjusted for accurate detection according to the temperature trend by utilizing the earth surface temperature distribution diagram and the spatial three-dimensional temperature distribution diagram, thereby positioning the fire range of the coal bed.
10. The positioning method based on the coal seam fire positioning system according to claim 9, wherein: in the second step, the wireless temperature sensor carries out 1wire coding encapsulation on the collected information; and 4.2), the information processing unit performs 1wire decoding processing on the information transmitted by the wireless multi-channel detection module.
