基于DSP的红外差分吸收型瓦斯传感系统

Infrared and differential absorption type gas sensor system base on DSP

针对目前传统瓦斯传感器的成本高、灵敏度低和稳定性差等问题,基于甲烷气体的近红外吸收光谱的特性,提出了运用高性能的微控制器(DSP)的方法来解决此问题,实现了对甲烷气体浓度高灵敏度、高稳定性和高精度的测量,对煤矿安全生产中的瓦斯事故预防意义重大。

In accordance with the high cost, low sensitivity, poor stability and other problems of the present conventional gas sensor, the paper, base on the infrared absorption spectrum features of the methane gas, provided a high performance micro-controller (DSP) plan to solve the problems.The micro-controller could have a high sensitivity to the methane gas density, high stability and high accurate measurement, which could have great significances to the gas accident prevention and control for the mine safety pro...
