发动机瞬时角速度的检测及其应用

Detection and Application for Engine Instantaneous Angle Velocity

本研究的主要目的是研制一个车上的微处理机装置,用于探测往复式内燃机的故障。讨论了2种用于故障探测的方法。第1种方法需要进行傅立叶变换计算;第2种方法则以自相关函数为基础,这2种方法都对相关研究提供了帮助。

The purpose of research is to develop a Microprocessor Unit （MPU） that is used to inspect the fault of reciprocating engines. Two methods to inspect the fault are discussed. The first one needs the Fourier counterchange. The second one is based on self-correlation function. They are helpful to other researches.
