Claim 5:
6. A method of complex gas mixture detection based on optical-path-adjustable spectrum detection, comprising the following steps:
S100: preparing a variety of standard gas samples with different components and concentrations, and using the device of complex gas mixture detection according to claim 1 to collect the spectral data of each of the standard gas samples under continuously changing optical paths so as to obtain a sample data set;
S200: analyzing the sample data set to obtain a three-dimensional spectrogram of absorbance, a wave number and an optical path length of each of the standard gas samples, so as to construct a three-dimensional spectrum library of the sample data set:
S300: using the three-dimensional spectrum library to train a deep learning model so as to obtain a gas mixture detection model; and
S400: using the device of complex gas mixture detection according to claim 1 to collect the spectral data of a gas sample to be detected under continuously changing optical paths, and constructing a three-dimensional spectrogram of the gas sample to be detected; and inputting the three-dimensional spectrogram into the gas mixture detection model, i.e., performing qualitative and/or quantitative detection of the gas sample to be detected.
