摘要
非分散红外吸收光谱法(NDIR)是CO浓度测量的主要手段之一。设计了NDIR的开放式CO气体测量系统及连续测量实验装置,对10种不同浓度的标准CO气体进行测量实验,分析了获取的40个实测数值。将遗传规划(GP)用于CO光强采样数据的建模,得到验证集的相关系数为0.999 7,验证集的相对误差最大值和平均相对误差分别为4.00%和1.11%。实测数据建模结果表明,GP可以用于NDIR方法的气体浓度数据建模,拟合误差较小,性能较好。
Nondispersive infrared absorption spectroscopy（NDIR） is an important method to measure CO concentration in the air.In the present study,an open-path measurement system and continuous measuring device was developed,and genetic programming was used to establish the calibration model of subjects＇ light intensity sampling values.Continuous measurements were carried out in 10 different concentration of CO,and 40 sampled data were acquired and analyzed.For validation set,the correlation coefficient was 0.999 7.The biggest relative error of validation was 4.00%,and the average relative error was 1.11%.Results show that genetic programming can be a good method for the modeling of gas concentration measurements equipped with NDIR systems.
