vibration pickup

基本解釋

The present invention relates to a turbine generator unit torsion vibration measuring method based on CCD image pick-up technique.
基於CCD攝像技術的汽輪發(fā)電機組扭振測量方法，本發(fā)明涉及一種汽輪發(fā)電機組軸系扭振的測量方法。

In this way, the output of the pick-up is a pure signal caused only by the rotary magnetic field, and the effects caused by the mechanical vibration, noise etc. can be eliminated.
此時傳感器的輸出信號是磁場引起的輸出信號，從而消除了機械振動及噪聲的影響。
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.
該方法是將拾振器的輸出信號作爲FIR橫曏濾波器的輸入，用自適應RLS算法對FIR橫曏濾波器系數(shù)進行辨識而最終獲得可以恢複拾振器原始輸入信號的反卷積濾波器。
