Study of early warning for servo-mechanism faults

Data acquisition is designed to collect the signals of current, vibration, etc. from the weather radar servo-mechanism. In order to achieve the purposes of early warning to the weather radar servo-mechanism faults, Wavelet packed feature extraction method is used in collection data, and the wavelet packed energy spectrum method is used to make the faults signals quantized and analyzed. The on-site installation verification test proved that the weather radar servo-mechanism faults diagnosis method is a more convenient and accurate method which is based on the wavelet packed enemy spectrum analysis.
