| Summary: | 实验物理和工业控制系统(EPICS)是大型物理实验装置常用的分布式控制系统软件。本文将EPICS引入到反应堆相关过程工艺控制领域,详细分析了钍基熔盐堆专项(TMSR)——硝酸盐熔(HTS)实验回路控制系统的基本设计思想和结构特点,通过HTS实验回路实现EPICS控制系统的操作。完成S7 PLC硬件驱动程序规范格式的改造,使其满足对Autosave、devlocState等插件的支持;完成ASYN和StreamDevice软件包在DTI-1000参考数字温度指示器串口设备通讯中的应用;完成EDM界面程序修改和熔盐流动、风机和熔盐泵转动等的Dynamic Symbols动态控件的构建等。经工程实践证明,EPICS控制系统可以满足以加热控制、变频控制以及温度、流量、压力等测量为主熔盐回路的控制要求,能够准确、美观地显示过程量的变化,在整个系统的可靠性分析和测试方面还需作进一步工作。 |

| Bibliography: | Background: Experimental Physics and Industrial Control System (EPICS) is the distributed control system software which is commonly used in large-scale experimental physics facilities. Purpose: We wish to apply it into the field of molten salt reactor relevant process control, e.g. HTS 1st test loop of thorium-based molten salt reactor (TMSR), which is characterized by heating, circulation, cooling and other process control. Methods: During the development of EPICS based control system, the Simense S7-300 PLC and Yokogawa FA-M3 PLC hardware drivers specification format transformation has been done, to support the Autosave and devIocState plug, and ASYN serial communication between the DTI-1000 reference digital temperature indicator and the EPICS IOC has been developed with the StreamDevice packages, also EDM interface program was modified to support PV control of the "molten salt flow", "fans", "molten salt pump rotation", etc. by dynamic symbols. Results: EPICS based control system achieved the standardized |
