摘要
为实现汽车尾气中CO、CO2、HC的定量测量,分析了ND IR(non-d ispersive infrared,非分光红外)实现测量气体浓度的工作过程.在此基础上构建了测量系统,给出了实际应用中硬件电路和软件程序的实现思路.经实际取样尾气测量实验证明,该方法测量准确、精度较高,且成本降低.
In order to implement the quantitative measurement of CO ,CO2, HC in vehicle exhaust gas the working process of measuring the gas concentration by using NDIR method is analyzed. And a measurement system is set up based on it. The implementation idea of the hardware circuit and software program in practical application is described. By testing the octual exhaust gas, it is verified that the method is exact and more precise than usual one.
