基于LabVIEW的汽车电控发动机信号采集与分析系统

Signal acquisition and analysis system of vehicle's electronic engine

随着汽车电子技术的发展,对汽车电控发动机各电信号的检测愈发重要。利用虚拟仪器技术及LabVIEW软件开发平台,配以数据采集卡,实现对发动机上各传感器和执行器产生的电信号进行采集与分析。通过试验证明,这种方法能够实时准确地对发动机上各种电信号进行采集,分析及显示。

With the development of vehicle electronic technology, acquisition signal of vehicle's electronic engine becomes more and more important. Using virtual instrument technique and software designing platform LabVIEW, with the data acquisition card, realizes the acquisition and analysis to the signal generated by kinds of sensors and executors on the engine. Engine testing proves that, this acquisition system can acquire, analyze and display all electronic signals of engine Real-time and accurately.
