摘　　要：受控核聚变能是最有希望成为下一代清洁能源的形式,在磁约束核聚变托卡马克装置中,长时间放电情况下等离子体与壁相互作用易造成壁材料损伤,影响装置的安全和使用寿命。EAST大视场红外内窥镜系统,可同时监测上下偏滤器、低杂波天线和活动限制器的表面温度。文中主要介绍EAST大视场红外CCD诊断系统的图像采集与处理,详细介绍了该系统的总体结构和软、硬件设计,包括图像存储、视频回放、格式转换以及基于TCP的远程传输。本系统已在EAST实验装置中成功运行,数据采集及服务系统性能稳定,运行可靠。它为加热功率的主动控制和等离子体位形控制提供了条件,为装置的安全运行提供了保障,充分满足了等离子体放电实验诊断的要求。Controlled nuclear fusion is the most promising clean energy resource of next generation. In magnetic confinement fusion Tokamaks ,plasma-wall interactions cause damage to materials during long-time plasma discharge easily, which makes a great influence on safety and operation life of the instrument. The infrared endoscope in EAST that has a wide field of view can monitor the temperatures of upper and lower divertors, LHW antenna and movable limiter. In this paper, the image collecting and processing of the infrared CCD diagnostic system in EAST during plasma discharge, and overall structure of the system, hardware and software design are introduced in de- tail,itaeluding image storage,playback,format conversion and remote transmission based on TCP protocol. Besides,the data acquisition and service system has been ran successfully and stably in EAST, which provides relevant information for active control of heating power and plasma shape control, and further provides the safeguard for safe operation of the equipment, and it well satisfies all requirements of the experimental diagnosis.
