Signal Process of Gas Monitoring System in Fiber Sensor

Abstract:

Gas monitoring has been the most important project in coal mining, and the main basis of gas is CH4. As a result, it is fatal to develop a safe and highly sensitive CH4 sensing system to detect CH4 concentration real-time. Moreover, signal process system is important for this sensing system. The novel signal process system was proposed in this paper, and phase lock amplifying and signal sampling processing technology was utilized to monitor CH4 concentration steadily and reliably. The experiment results indicated that the steady is 0.4%, and relative error is less than 0.02%. So this signal process system is feasible and effective, and can meet the requirement of technology
