Research of Gas Detection System Based on Stochastic Resonance

In view of the problem that gas concentration information in the detected signal of coal mine underground is weaker, the paper proposed a design scheme of gas detection system based on stochastic resonance. It analyzed principle of stochastic resonance, introduced structure of gas detection system based on multi-layer stochastic resonance algorithm, and gave simulation and numerical analysis by taking double-layer stochastic resonance model as example. The result showed that the system can be uninfluenced by underground noises and can get relatively accurate gas concentration information.
