摘要
针对空气污染、全球变暖等问题,设计了一款气体检测仪器,主要对汽车排放的气体进行分析,通过气体传感器,利用红外光谱分析的原理对CO、CO_(2)、HC、O_(2)、NOx这5种常见汽车尾气进行检测。特别设计了一系列分析体系,包括检测的原理过程、整体架构分析、系统优化设计、系统测试等。实验结果表明,此款检测分析仪具有良好的稳定性,并且相对于以往的检测装置,它的灵敏度较高,携带更方便,不受其他因素干扰。
A gas detection instrument is designed for air pollution,global warming,etc.,which mainly analyzes the gas emitted by automobiles.The gas sensor uses the principle of infrared spectroscopy to analyze CO、CO_(2)、HC、O_(2)、NOx.Five common car exhausts are tested.The system has specially designed a series of analysis systems,including the principle process of detection,overall architecture analysis,system optimization design,system testing,etc.Experimental results show that this detection analyzer has good stability,and compared with the previous detection device,it has higher sensitivity,more convenient to carry,and is not interfered by other factors.
