Research of neural network application in methane gas spectrum sensing system

摘要

Laser spectroscopy combined with neural network approach is a new method of monitoring coal mine gas. This research analyses of gas concentration and predicts the process of modeling using BP neural network finds changes law of concentration, gives the various parameters settings of neural network. Experimental results show that, BP neural network for early warning of gas concentration is feasible. The study meets an online, real-time, fast agreement of China's Coal Mine Gas monitoring systems.
