摘要
基于Lab VIEW的转子轴心轨迹PXI技术监测系统，首先在转轴同一横截面上安装2个相互垂直的电涡流位移传感器，使用AI Acquire Waveforms函数同时采集2个传感器传入的水平和垂直信号；然后再以Index Array函数分别索引2路信号，经Butterworth Filter低通数字滤波器滤出高频分量后，将2路信号叠加并在XY Graph控件显示，画出转子轴心轨迹图。
The axle center trail PXI technology monitor system is based on LaVIEW. Firstly, two mutual vertical vortex sensors were installed in the same cross section; the horizontal and vertical signals are acquired by AI Acquire Waveforms function. Secondly, two signals were indexed by Index Array function, and the high frequency is filtered by Butterworth low-pass filter. Finally, two signals are superposed and displayed in the XY Graph control for axle center trail chart.
