Abstract
In this paper, with regards to the disadvantages of traditional gas sensor used in mine, an intelligent infrared detection method for methane gas based on Non-dispersive Infrared technology is presented. Through the introduction of the principle of infrared spectrum absorption, further to the adoptions of differential measurement method and the technology of single light beam & dual wavelength detection, the relationships between pyroelectric detector signal and gas concentration has been analyzed in details. A relevant formula has been given for between the gas absorption ratio Fa and the peak value of pyroelectric detector terminal voltage. Experimental results show that the measurement error is less than ±0.1% (when concentration of methane gas <4%), and meet the requirement of coal mine safety operation.
