Abstract: A energy spectrum method with wavelet transformation is used, the result shows that this method is better than frequency ratio estimation method, and can get the difference of 5g bolt from 12g nut. In the graph, the change of impact energy is shown. Wavelet frequency ratio method gives a better way to falling part’s mass estimation.

Key words: Loose parts monitoring system, Mass estimation, Reactor, Wavelet transform
