摘　　要：计算机技术与测试测量仪器技术的结合,出现了新的测试仪器——虚拟仪器(VI),采用虚拟仪器的软件战略是第三代自动测试系统的发展方向.本文结合VI编程语言平台LabVIEW实现了机动车尾气浓度检测系统的编写,借助此系统可以实现机动车尾气中CO和CO2污染气体浓度的检测.该系统主要包括气体标定模块,数据库模块和利用PCI-6221数据采集卡的数据采集分析模块3部分.利用LabVIEW软件大大缩短了软件的开发周期,设计出实用方便的系统,最终实现了检测的功能.The combination of computer technology and technology of test instruments results with the appearance of a new test instrument, virtual instruments （VI）. The software strategy of VI is the developing trend of the third generation of automatic test system. The thesis combines with the VI programming language platform LabVIEW, finishes the concentration detecting system for motor vehicles exhausts and implements the concentration detecting of CO and CO2 in virtue of the system. The system mainly includes three modules ： calibration module, database module and data acquire and analyze module of using PCI - 6221 DAQ card. With the help of LabVIEW, the developing period of software has been shorten and we design the useful and convenient system to implement the detecting.
