Design of the Vibration Pick-Up Model GCS-1 for Engineering Survey GCS-1型工程测振仪拾振器的设计研究
In order to compensate the measurement error of measuring result caused by limited band of a vibration pick-up and its measurement system, a method for recovering the original input signal of the vibration pick-up using FIR transversal filter is presented. 为了补偿由于拾振器及其测量系统有限带宽而使测量结果产生的测量误差,本文提出了一种用FIR横向滤波器来恢复拾振器原始输入信号的方法。
The coefficients of the FIR transversal filter was identified by using adaptive RLS algorithm while the output signal of the vibration pick-up was input into the FIR transversal filter. An inverse-convolution filter was acquired to recover the original input signal of vibration pick-up. 该方法是将拾振器的输出信号作为FIR横向滤波器的输入,用自适应RLS算法对FIR横向滤波器系数进行辨识而最终获得可以恢复拾振器原始输入信号的反卷积滤波器。
