| 摘 要： | 介绍了一种利用LABVIEW采集光纤陀螺输出信号的方法。通过PC机上的RS232接口与光纤陀螺相连,利用LABVIEW中的串行通信模块实现及对光纤陀螺数据的采集。分析了光纤陀螺的静态输出信号,为了抑制光纤陀螺随机噪声,利用五点三次平滑、数字滤波、小波变换分析法对光纤陀螺静态输出数据进行了滤波处理,利用Allan方差分析了各误差源的幅度,结果表明:小波阈值滤波的方法能够有效的补偿光纤陀螺的随机误差。 |

| Abstract: | A method of FOG output signal acquisition by using LABVIEW is introduced.FOG is connected through RS232 interface in the PC.By using serial communication module in LABVIEW,acquisition of FOG output data has been realized.FOG signal from experiments were analyzed.In order to restrain the FOG random drift,filter is carries on using three smoothness ever five points,and the wavelet analytic method to the FOG static output,The amplitude of various error sources in FOG noise can be obtained by using the Allan va... |
