大型ICF实验物理诊断系统的集中控制设计
Design of central control system for physical diagnosis in ICF experiment

摘要: 大型惯性约束聚变(ICF)实验中需要配备精密的物理诊断集中控制系统，以保证实验能够安全、高效地进行。针对国内正在建设的ICF大型激光装置，提出了一个完整的物理诊断集中控制系统构建框架。该ICF的物理诊断集中控制系统分两个层次。上层是管理控制层，由大型计算机组建的工作站和服务器构成，提供集中式操作控制、状态报告、数据采集、管理、处理和集中显示。下层是由大量嵌入式处理器构成的实时控制层，它直接面对装置各部分的控制点，由上层管理系统来协调下层每个处理器工作。采用现场可编程门阵列(FPGA)技术为该系统设计了两个子控制系统：在FPGA上为指令同步系统实现了一个高性能的嵌入式片上系统平台；利用FPGA将同步触发信号系统整合到PXI系统中实现集中控制。Abstract: Large ICF experiments require their physical diagnosis systems to be equipped with a sophisticated central control system, which makes sure the whole experiment would be safe and efficient. An integrated central control system framework for physical diagnosis system serving for domestic ICF large laser device, which is being built, is brought forward. Two subsystems in the central control system are designed with field programmable gate array(FPGA) technology, implementing a high performance embedded system on chip(SoC) platform for instruction synchronous system in FPGA and integrating the synchronous trigger system into a PXI system for central control by FPGA.
