摘要
设计了一个以FPGA芯片EP3C120F780为控制核心的高速高精度采集卡,实现了对1MHz-80MHz频率信号的精确采集,并能实时地将数据处理后通过千兆以太网送给上位机。整个系统包括了电源管理、信号预处理、信号转换、数据存储、数据传输和主控制等六个部分。整个系统大部分采用了现代高端产品与技术,能够很直接、实时地对数据进行转换和传输,因此在工业生产和高校科研方面有比较广泛的应用。
This paper designs a high-speed and high-precision data acquisition card based on FPGA chip EP3C120F780 to achieve accurate acquisition of signals ranging from 1MHz to 80 MHz and transferring the data to upper computer via gigabit Ethernet after real-time processing. The entire system consists of six parts as followed: power management, signal preprocessing, signal conversion, data storage, data transference and main controller. Most of the whole system introduces modern high-end products and technologies. It can do real-time data conversion and transmission, so it is a wide range of applications in industrial production and scientific research for universities.
