| Abstract: |
| This paper combines tunable laser absorption spectroscopy (TDLAS) to study the complete distributed laser methane monitoring system, including the overall architecture design of TDLAS monitoring system, light source and gas sensor, photoelectric conversion, information acquisition and so on. The difficulties in methane detection design are also analyzed and the distributed laser methane monitoring system proposed in this paper has a distinct advantage comparing with the other online gas monitoring system of multiple monitoring points at home and abroad. |
