Infrared spectrum is also known as molecular fingerprint. The infrared spectrum characteristics of different gas molecules are different. Most toxic and harmful gases have characteristic peaks in the infrared band. Fourier transform infrared spectroscopy technology uses the infrared spectrum characteristics of gases for detection and analysis. It can achieve qualitative identification and dynamic quantitative inversion of toxic, harmful and hazardous gases in the target gas cloud. It can intuitively view the type of monitored gas, the dynamic distribution of real-time concentration, the diffusion range and direction, thereby realizing long-distance automatic detection and imaging, which is widely used in gas leak monitoring, fire and other fields.
[0003] In the existing technology, for forest fires, urban firefighting and other fields, due to the uncertainty of the accident location and the uncontrollability of the accident scope, it is usually necessary to use the vehicle-mounted warning system to perform mobile gas telemetry imaging.
