A method for rotor current signal denoising in maglev gyro total station directional data system

LI Xiao-li;ZHOU Zhi-yi;School of Civil Engineering and Hydraulic,Hefei University of Technology;School of Geological Engineering and Geomatics,Chang'an University;  
The noise of rotor current data in the directional system for the maglev gyro total station is one of the important factors affecting the accuracy of the instrument orientation.In the paper,through the statistical analysis,it was known that the rotor current signal is non-stationary.After the comparative analysis,the rotor current signal was de-noised with wavelet threshold by determination of the specific threshold and wavelet function.The optimal decomposition level was determined by the characteristic that the multiclass evaluation index variation including of SNR,the root mean square error and smoothness converge with the increase of wavelet decomposition levels.The experimental results showed that the method could realize the effective separation between rotor current signal and noise signal,eliminate the noise of the rotor current observation data under different observation conditions,and improve the directional accuracy of the instrument.
