| Abstract: | Data acquisition is designed to collect in real time the signals of vibration from the weather radar servo motor. In order to realize early warning of weather radar servo motor faults, wavelet packet feature extraction method is used in collection data, and the wavelet packet 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 motor faults diagnosis method is a more convenient and accurate method. |
| Keywords: | weather radar wavelet packet energy spectrum early warning for the faults servo motor |
