基于小波阈值方法对装载机实测信号进行降噪处理,并以关联维数作为描述装载机运行状态的特征量。通过对小波类型、分解层数以及小波阈值函数对信号降噪效果的分析,建立起实测信号的小波降噪方法,然后采用关联维数对运行状态特性进行提取,有效提高了运行状态检测的准确性。
Based on the wavelet threshold method, the measured signal of the loader is denoised, and the correlation dimension is used as the feature quantity to describe the operating status of the loader. By analyzing the signal denoising effect of wavelet type, decomposition level and wavelet threshold function, a wavelet denoising method of the measured signal is established, and then the correlation dimension is used to extract the running state characteristics, which effectively improves the accuracy of the running state detection Sex.
