摘要
Problem to be solved: to provide a gas concentration detecting apparatus, a gas concentration detecting system and a gas concentration detecting method for detecting a gas concentration based on a comparison between a reference gas signal generated from a received signal and a received signal.A gas concentration detecting apparatus 200 according to the present invention comprisesLaser light output from a laser light source driven by a sawtooth shaped driving currentA detector 210 which is detected through a measurement spaceA received signal output section 240 for outputting a received signal corresponding to the detection result of the detector 210 andAn edge detection part 220 for detecting an edge of a received signal andBased on the detected timing of the edgeA saw wave signal of sawtooth shape is included in the received signal.A reference gas signal output 230 for outputting as a reference gas signalBased on the comparison between the received signal and the reference gas signalA gas concentration detector 250 for detecting a gas concentration included in the measurement space 400 and.Diagram
