It,1It is characterized waveband infrared spectrum response intensity, It,1For the waveband infrared spectrum response intensity of reference；I0,lIt is characterized
Waveband infrared spectrum response initial strength, I0,lFor the waveband infrared spectrum response initial strength of reference；And then calculate concentration index such as
Under：
Rt=R0×e-[E(λ1)-E(λr)·C×L]；
Wherein, E (λ l) is the exponential function relevant with the centre wavelength of characteristic wave bands, E (λ r) be with reference wave band
Cardiac wave grows relevant exponential function；
RtFor the ratio between real-time light intensity, RtEqual to It,1/It,r；
R0For the ratio between background light intensity, R0Equal to I0,1/I0,r；
In practical operation, when the C and L product being calculated are more than LEL × m, (LEL × m makes a reservation for equivalent to above-mentioned
Product threshold value LEL is the LEL of dangerous matter sources gas, and m is distance parameter) when, then send dangerous matter sources gas alarm.
