摘　　要：在全超导托卡马克核聚变实验装置(EAST)上进行核聚变试验时,离子回旋共振加热(ICRF)是该试验过程中加热等离子体的主要方法之一,而对发射机、传输线、真空室以及天线中的重要参数进行实时监测是托卡马克装置中ICRF对等离子体进行功率耦合的重要保障。提供了一种采用FPGA的ICRF实时监控系统设计方案、AD9252芯片以及SN74LS14型号施密特触发器进行数据采样,实现对各故障信号的实时显示、报警以及信号源的及时切断,同时利用FPGA可重复编程的特点,便于后期对系统进行维护和升级。In the EAST tokamak nuclear fusion experiment,Ion Cyclotron Resonance Heating(ICRF)is one of the important means to heat the plasma in the process of the experiment.Real-time monitoring of important parameters in transmitters,transmission lines,vacuum chambers and antennas is an important guarantee for the power coupling of plasma by ICRF in tokamak devices.This paper proposes a design scheme of ICRF real-time monitoring system based on FPGA.AD9252 chip and SN74LS14 Schmitt trigger are used for data sampling to realize real-time display of each fault signal,alarm and timely cut-off of signal source.At the same time,FPGA is used.The feature of repeatable programming is convenient to maintain and upgrade the system later.
