【摘要】 提出了一种基于小波包分解的惯性器件故障检测与诊断方法,该方法利用小波包精确细分的特点,分别对正常系统和故障系统的观测信号进行小波包分解,提取其特征信息,从而实现对惯性器件的故障诊断。并且给出了故障诊断的硬件原理图。实验表明,该方法具有很好的工程实际应用价值。更多还原

【Abstract】 A method of fault diagnosis for the inertial apparatus based on Wavelet Packet is discussed. Based on the characteristic of accurate partition, the testing signals of the normal and fault system are analyzed by Wavelet Packet. The characteristic information is distilled and the inertial apparatus’ fault is diagnosed. The appropriate design of the hardware circuit is shown, and the method adopted in this article is proved to be correct by the experimental data.更多还原
