Temperature Signals of Bearing De-noising Based on Biorthogonal Wavelet Transform

针对实际消噪应用中小波基的多样性要求,探讨了在不同噪声水平下,具有正交性的小波基和具有线性相位的双正交小波基对消噪结果的影响,提出了选取小波基的一般方法,并基于此方法利用双正交小波基实现了对煤矿机电设备轴温信号的消噪处理,并取得了较好的效果。

In view of the actual de - noising application in the wavelet base ＇ s multiple request, has discussed under the different noise level, with the orthogonal wavelet base and the linear phase biorthogonal wavelet base to the de -noising result influence, proposed the selection wavelet base＇s general method, and has realized based on this method using the biorthogonal wavelet base to the temperature signals of bearings de -noising processing in coal mine electromechanical device, and has achieved the good progress.
