摘要
机动车排放尾气成为很多城市大气质量恶化的主要原因之一,机动车尾气遥测系统利用可调谐二极管激光吸收光谱技术及其计算机自动识别技术可以在不影响车辆正常行驶的条件下,在道边对机动车尾气成份中的CO,CO2进行实时遥测。实验表明,基于该技术的尾气遥测系统可以迅速、方便地获得大量机动车的实时尾气排放数据和车辆信息,从而快速筛选出那些高排放的车辆。该系统是传统尾气检测方式的补充。
Now almost every major city in China faces air problems associated with emissions from motor vehicles.Remote sensing based on tunable diode laser absorption spectroscopy is capable of reflecting the characterization of vehicle emissions without interrupting the traffic driving conditions.The on-road vehicle emissions remote sensing system is presented,which has an infrared component for detecting CO,CO2.In parallel,the plate license,speed and acceleration of vehicles are recognised by computer.The system can be taken as a complement to our traditional mobile source emission control program.
