基于FPGA的多路交流信号同步采集系统的实现

分析了传统微机继电保护数据采集及存储结构,提出一种多路交流信号同步采集的设计方案。设计采用自顶向下的设计方法,使用一片FPGA完成A/D采样控制和数据存储的集成。解决了传统的数据采集系统运行效率不高,软件编程复杂的问题,实现了数据同步采集及存储和通道可选择控制等功能,此外给出了使用嵌入式逻辑分析仪的测试结果。

Implementation on multi-channels data synchronous acquisition system based on FPGA

This paper introduces data acquisition and storage structure of traditional microprocessor-based protective relaying and presents a new multi-channels data synchronous acquisition system based on FPGA.This new system integrates data acquisition and data storage in one FPGA to resolve problems of inefficient performance and complicated program in traditional data acquisition and implement data synchronous acquisition as well as the optional number of channels.Some test results used by embedded logic analyzer are presented.
