此项工作的主要目的是发展一种在运输工具上检测往复活塞式内燃机故障的微处理机装置,本文论述了用于故障检测的两种分析方法,第一种方法需要傅里叶变换的计算,而第二种方法则是以自相关函数为基础。两种方法为迄今很少进行的研究提供了鼓舞人心的结果。
The main objective of this work is to develop a microprocessor device for detection of reciprocating piston internal combustion engine faults on a vehicle. This paper presents two methods of analysis for fault detection. The first method requires calculation of the Fourier transform , While the second method is based on the autocorrelation function. Both approaches provide inspiring results for studies that have been scarce so far.
