[0020] In the utility model, through infrared sensor 9 based on non-dispersive infrared (NDIR) technology, the absorption characteristics of specific wavelength infrared light of methane and other combustible gases are detected, and the specific working principle is as follows:

[0021] The infrared light source emits infrared light of specific wavelength, which passes through the gas to be measured, and the methane molecules have strong absorption effect on the infrared light of specific wavelength, and the absorption intensity is proportional to the gas concentration. The infrared detector receives the light signal after passing through the gas, and calculates the gas concentration by measuring the attenuation degree of light intensity. The infrared sensor 9 has high sensitivity, selectivity and stability, and is suitable for accurate detection of low concentration methane.

[0022] Meanwhile, it can also be detected by laser spectrum module 7, which is based on tunable diode laser absorption spectroscopy (TDLAS) and detects through the interaction of laser beam and gas molecules. Its working principle is as follows:

[0023] The laser emits laser of specific wavelength, and the laser wavelength matches the absorption spectrum of methane molecules. When the laser passes through the gas to be measured, the methane molecules absorb laser energy, resulting in attenuation of laser intensity. The detector receives the laser signal, and determines the gas concentration by analyzing the intensity and characteristics of the absorption spectrum. Laser spectrum technology has high precision, fast response and long distance detection capability, and is suitable for high concentration methane or complex environment.

[0024] It can also be detected by the double spectrum cross detection principle, that is, the infrared sensor 9 and the laser spectrum probe work at the same time, respectively detect the methane concentration independently, and the detection results of the two are cross verified and calibrated through data fusion algorithm, when the detection results of the two technologies are consistent, the final concentration value is output; when the results are inconsistent, trigger alarm and troubleshoot, the double spectrum cross detection technology significantly improves the measurement accuracy and reliability, reduces the possibility of false alarm and omission.
