| 摘 要： | 针对目前煤矿井下瓦斯浓度检测技术存在的不足,在红外光谱差分吸收检测模型的基础上设计了单波长双光路的瓦斯浓度检测仪。在实验室环境下测量不同瓦斯浓度下检测仪输出的电压值,得到二者之间的拟合曲线,对测量结果的分析可以看出该系统的测量误差<2.5%,甲烷浓度检测能力较宽,满足煤矿瓦斯浓度检测的要求。

| Abstract: | According to the disadvantages of the methane sensor in coal mine recently,double light beam and single wavelengths methane concentration detector was designed using differential absorption technology.voltage of detector was Measured with different gas concentration in Laboratory environment,from which fitting curves of the voltage and gas concentration can be Obtained,Experiment shows that measurement error is less than 2.5%,and the system has very high measurement precision which can meet the requirements of the methane concentration detection in coal mine. |
