分析了傅里叶变换红外光谱仪(FTIS)遥测的目标气体和几种干扰物的红外光谱特征,给出红外光谱的模式识别方法用于远距离有毒气体环境的监测。用选定的标准样本进行训练,得到稳定的权值和阈值。该方法适合于对局部环境内有毒、有害气体成份的远距离实时监测。具有较高的识别率。应用的结果表明:该方法对特定成份的局部环境监测是十分有效的。
The infrared spectra of the target gas and several interfering substances in the FTIR telemetry are analyzed. The pattern recognition method of the infrared spectroscopy is given for the monitoring of the long-distance toxic gas environment. Training with selected standard samples gives a stable weight and threshold. The method is suitable for long-distance real-time monitoring of toxic and harmful gas components in the local environment. Has a high recognition rate. The application results show that this method is very effective for the local environmental monitoring of specific components.
