便携式多通道数据采集系统设计

Design of Portable Multi-channel Data Acquisition System

摘要:

在EAST全超导托卡马克核聚变放电实验中,某些信号需要低功耗、便捷的进行独立同步采集与分析；而现有的大型采集系统并不能满足此需求,所以需要设计一套低功耗的、便携式的多通道数据采集系统来保障EAST实验的顺利进行;系统具有界面友好、性能稳定等诸多优点;在LabVIE软件编程环境中,系统能够实现对多达32路信号的同步采集、实时显示、数据存储、数据分析以及历史数据回放等功能;经过实验测试,该系统运行稳定可靠,完全满足EAST实验的数据采集需求。

Abstract:

In the experiment of experimental advanced superconducting tokamak (EAST),it requires low power consumption,convenient to some signals for synchronous acquisition and analysis independently; but the existing large acquisition system cannot meet the demand,so need to design a set of low power consumption and portable multi-channel data acquisition system to ensure EAST experiments success. The system has many advantages such as friendly interface,stable performance etc. In the software programming of LabVIEW,the system can realize synchronous acquisition,real-time display,data storage,data analysis and historical data playback of as many as 32 channel signals. Through the experiment test,the system run stably and reliably,fully meet the demand of experiment for data acquisition.
