Hilbert Envelope Loose Part Location Method Based on Continuous Wavelet Transform

In this paper, combined with time-frequency analysis, the impact signal arrival time was determined by the method of calculating the Hilbert envelope maximum based on the analysis of impact signal by continuous wavelet transform (CWT), and it was applied to grid localization. The results show that this method has strong anti-interference capacity and high locating accuracy, and for the small mass loose parts it also can accurately locate their position.
