Design of digital twin-based control system for loading and unloading of proton beam irradiated thorium target

  • 摘要: 针对质子束辐照钍靶装卸系统在低辐射、大尺度、高复杂性等操作环境下,传统的单机控制故障率高、维护难、灵活性差、人工操作危险的问题,提出了一种基于可编程逻辑控制器(PLC)冗余的数字孪生质子束辐照钍靶装卸系统控制方法。首先,该方法采用CPU冗余、I/O冗余、电源冗余等多要素协调控制策略,通过对硬件热备冗余系统的搭建和软件冗余系统的组态、编程及仿真,使控制系统不间断运行。其次,基于“NX MCD+PLC SIM+OPC”架构设计了数字孪生虚实交互的控制系统,对物理空间的数据信息在虚拟空间构建靶片装卸系统孪生模型,实现辐射环境下无人值守的连续监控;最后,经过实验与可靠性分析,所提方法使此控制系统的稳定性提升至99%,为辐照环境下操作系统的管控提供了一种新思路。
