The Design Of Signal Acquisition System Of Micro Mechanical Gyro And The Research Of Flitering Method

Although the output signal of micro mechanical gyro is low precision, the error is large.But due to their small size, bulk , easy intergration and other advantages, micro mechanicalgyro has broad application prospects. .In order to improve the precision of the gyro,It isnecessary to identificate the noise source and reduce the noise of the gyro.Traditional waveletsoft threshold, hard threshold method can improve the precision of gyro ,but the defect of softthreshold method is the too smooth of the signal reconstruction. The defect of hard thresholdis the oscillation of the signal . In response to these issues, propose the method of combiningthe soft, hard threshold ,Through the experiments,the good effect is verfied.In addition , theoutput of micro mechanical gyro is multiplex signal.Sometimes,it is necessary to gather a lotof gyro signal,so It is meaningful to design data acquisition system.To collect the multiplexsignal ,it is worthy to design the system of the acquisition and storage.The system can collectthe multiplex signal at the same time ,achieving the good result we need .At last ,Based onthe platform of the labview ,the Virtual Denoisor is designed by Hybrid programming...
