The invention is suitable for the technical field of mining poisonous and harmful gas concentration detection, and particularly relates to a mining poisonous and harmful gas concentration detection method based on a single-point calibration fitting algorithm. According to the method, the obtained actual output value of the mine poisonous and harmful gas sensor is subjected to normalization processing to obtain the target data, and the target data and the mine poisonous and harmful gas concentration values corresponding to the four preset reference points are substituted into the target function to obtain the gas concentration value. According to the invention, the concentration of the mining toxic and harmful gas is detected through the single-point calibration fitting algorithm, and the precision of the concentration detection of the mining toxic and harmful gas is improved on the premise that the hardware cost is not increased.
Description
technical field [0001] The invention relates to the technical field of gas concentration detection, in particular to a method for detecting the concentration of toxic and harmful gases in mining based on a single-point calibration and fitting algorithm. Background technique [0002] Mine toxic and harmful gas detector is suitable for on-site detection in various places such as coal mines, metallurgy, coking, environmental monitoring, and tunnel operations. It can measure the concentration of toxic and harmful gases in tunnels or places that people cannot reach. Mine toxic and harmful gas detectors include various types, which can measure the concentration of different toxic and harmful gases. For example, carbon monoxide mine toxic and harmful gas detectors can be used to detect the concentration of carbon monoxide toxic and harmful gases in places. [0003] The detection method of the existing mine toxic and harmful gas detector adopts an ideal linear calibration method, th...
