Tunnel multi-component high-risk harmful gas detection system and method based on spectrum technology

The invention provides a tunnel multi-component high-risk harmful gas detection system and method based on a spectrum technology, and relates to the technical field of tunnel high-risk harmful gas detection.The tunnel multi-component high-risk harmful gas detection system comprises a data acquisition module used for acquiring an infrared spectrum image of a gas sample in a tunnel with the wavelength range of [# imgabs0 #] and collecting environmental influence parameters in the tunnel to be detected in real time, the environment influence parameters comprise temperature data and air pressure data in the tunnel. The detection value of the absorption peak wavelength, the detection value of the light absorption frequency and the detection value of the light absorption intensity of the gas sample in the spectral image are extracted, the collected temperature data, air pressure data and gas attribute parameters are analyzed and processed, the gas attribute parameters of the sample are corrected, and the detection
