摘要

The online monitoring of the Coal Mine inflammable and explosive gases based on optic fiber sensing technologies, is the main research of spontaneous combustion forecasting system of coal goaf area. In use of the Lab View's virtual instrument development capability, CO concentration monitoring virtual system has been established based on the tunable diode laser absorption spectroscopy(TDLAS) technology. According to comparison of the results of the virtual simulation system and the actual monitoring system, indicate that the virtual system can reflect the impact of second harmonic by dynamic parameters such as concentration, temperature and pressure truly and accurately, provide theoretical guidance and reference for the overall design of the gas monitoring system.
