基于FPGA的振动信号采集卡的研究与设计

摘要

It is very important to research on and apply mechanical vibration monitoring and analysis system of rotating machinery.This paper introduces an analog-digital signal conversion chip AD7606 with FPGA as data processing core and takes high precision acceleration sensor as the front-end signal acquisition source,at the same time,uses the PC software to realize the recurrence of the signal.It also briefly describes the research and design of acquisition card for multi channel vibration signal.%旋转机械的振动监测与分析系统的研究与应用有着重要的意义.介绍了一种以FPGA为数据处理核心、AD7606为模数信号的转换芯片,利用高精度加速度传感器为前端信号采集源,同时具备上位机软件对信号进行复现.简要说明多通道振动信号的采集卡的研究与设计.
