摘要
EAST瞬态电场测量系统检测放电时EAST装置周围的瞬态电场分布及强度,为电磁兼容(EMC)设计提供依据。该系统由单极子电场探头、光电隔离设备、NI数据采集设备构成硬件平台,利用LabVIEW进行软件编程,对采集的数据进行处理。经过测试,该系统可实现16个模拟通道、20MHz采样率同步数据采集,高达650MB?s-1的数据吞吐量,满足了高频模拟信号的多通道实时数据采集,处理和存储要求。
The EAST transient electric field measurement system is designed for detecting the distribution and intensity of the transient electric field while the EAST is discharging, and can provide the basis for electromagnetic compatibility （EMC） design. It is composed of monopole electric-field probe, photoelectric isolation device, NI data acquisition equipment and software developed on LabVIEW to deal with the data. By testing, it can make synchronous data acquisition with sixteen analog channels, 20MHz sampling rate and up to 650MB·s-1 throughput separately, which is able to meet the demand of acquiring, processing and storing the real-time data in the high-frequency analog signals multi-channel mode.
