旋转机械振动检测装置数据采集的实现

Implementation of Rotating Machine Vibration Signals Acquisition System

介绍用CPLD ,AD和FIFO实现一时序严格的、由硬件自动完成数据采集的电路 ,它能够自动跟踪转速信号的变化 ,解决了旋转机械在不同转速下的抗混叠滤波的问题。

A circuit which has a strict time order and can automatically acquire data is realized by using CPLD,AD and FIFO. This circuit solves the problem of anti-aliasing filtering when the rotational speed of a machine is not constant.
