基于小波变换的轮速信号奇异性检测研究

Research on Singularity Detection of Wheel Speed Signal Based on Wavelet

基于小波奇异性检测原理,提出了一种检测奇异性轮速信号的算法。利用该算法对采集到的轮速信号进行处理,结果表明:该算法能够提取轮速信号丢失的奇异特征,即信号丢失现象,且运算量较小,为ABS系统的故障诊断研究提供了一定的理论基础。

An algorithm of singularity detection of wheel-speed signal was proposed based on wavelet transform, which was applied in processing wheel-speed signals. The result shows that it can identify ＂loss＂ characteristics of the wheel-speed signal with less operation, and provides a theoretical basis for the research of ABS diagnosis system.
