Abstract
For the detection of methane (CH4) gas concentration in some mining complexes, the paper studies and discusses two kinds of easily-realized CH4 gas opticfiber sensor, that is infrared absorption CH4 gas optic fiber sensor and thin film transmission CH4 gas optic fiber sensor. The optic structure of the sensor is discussed, and the paper compares the difference between the single optic structure system and the double one. It puts forward a multipoint long-distance detection system constructed by the micro- computer small system and the upper computer, and discusses the hardware and software system.
