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(shù)的汽輪發(fā)電機(jī)組扭振測(cè)量方法，本發(fā)明涉及一種汽輪發(fā)電機(jī)組軸系扭振的測(cè)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(shí)傳感器的輸出信號(hào)是磁場(chǎng)引起的輸出信號(hào)，從而消除了機(jī)械振動(dòng)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(hào)作爲(wèi)FIR橫曏濾波器的輸入，用自適應(yīng)RLS算法對(duì)FIR橫曏濾波器系數(shù)進(jìn)行辨識(shí)而最終獲得可以恢複拾振器原始輸入信號(hào)的反卷積濾波器。
