用于HIRFL核能材料辐照实验的远程控制平台研发

Research of Remote Control Platform for HIRFL Nuclear Materials Irradiation Experiment

  • 摘要: 针对兰州重离子加速器(Heavy Ion Research Facility in Lanzhou, HIRFL)核能材料重离子辐照实验过程中自动化控制问题,提出以TCP (Transmission Control Protocol)协议为核心的远程控制系统方案。由于实验建设条件限制,实验终端缺少网络传输功能,为减少电离辐射对实验人员的身体伤害,采用串行通信和TCP协议通信的方式,实现辐照终端设备的远程操作和监控。针对材料辐照实验的统计数据之一—束流强度和粒子数,因原有设备建设较早,无法实现计算机自动记录,本工作开发了一种专用型图像处理软件,可实时记录辐照实验中的辐照剂量,经数据集测试该软件的处理成功率达97%。最后,经现场运行测试,整个控制平台运行平稳,满足材料辐照实验需求。

     

    Abstract: Aiming at the automation control problem in the heavy-ion irradiation experiment of nuclear energy materials at HIRFL, a remote control system scheme centered on the TCP protocol is proposed. Due to the limitations of the experimental construction conditions,the experimental terminals lack network transmission capabilities. To reduce the physical harm of ionizing radiation to experimental personnel,serial communication and TCP protocol communication are adopted to achieve remote operation and monitoring of irradiation terminal equipments. Regarding the beam intensity and particle number, which are among the statistical data of material irradiation experiments, the original equipment was built earlier and cannot achieve automatic computer recording. In this work, a dedicated image-processing software has been developed,which can record the irradiation dose in the irradiation experiment in real-time. After testing with the dataset, the processing success rate of this software reaches 97%. Finally, through on-site operation tests,the entire control platform operates stably and meets the requirements of material irradiation experiments.
