EAST嵌入式数据采集系统设计

Embedded Data Acquisition System for EAST

介绍了EAST核聚变装置中嵌入式数据采集系统的设计,该系统基于FPGA和ARM技术,集成信号调理、数据采集和数据处理于一体,便于放置于实验现场进行采集,具有较高的集成度和便捷性。同时,针对聚变实验的稳态运行,该系统引入了时间片技术,实现了长时间采集和数据实时传输。

The embedded data acquisition system for the Experimental Advanced Superconducting Tokamak（EAST） was designed.This system is based on the FPGA and ARM technology,integrates signal conditioning,data acquisition and processing into the single board,and provides a high integration and portability level architecture.At the same time,the ＂time sliced＂ technology is introduced into the software system for providing a continuous acquisition and quasi real-time data transferring capability.
