为了满足HL-2A托卡马克装置放电日益增长的实验要求，提高HL-2A主机集中控制系统的集成度，本文设计了一种基于PXI Express的高速数据采集系统。为了使快速采集系统能够集成到EPICS平台下的HL-2A主机集中控制系统中进行集中控制和管理，主要介绍了如何通过EPICS平台下的PON网络实现基于c#的快速采集信号系统与上层OPI的通信。数据采集系统硬件采用基于pxie的机箱、嵌入式控制器和高速同步采集卡，具有机械封装好、模块化程度高、采样率高的优点。软件采用基于微软的测控系统开发平台。. NET平台，Visual Studio开发环境和Visual c#语言。本文研究了Epics c#库，开发了Epics Server应用程序，实现了HL-2A主机工程系统状态和参数的远程控制。系统在HL-2A装置2018实验中稳定运行。结果表明，该系统能在10KSps采样率下稳定工作，能较好地满足器件运行的需要。完成了HL-2A托卡马克主机集中控制系统的基本框架。并且该技术和方法可以为下一代设备HL-2 M主机集中控制系统的设计提供参考，打下良好的基础。
In order to meet the increasing experimental requirements of HL-2A tokamak device discharge and improve the integration of HL-2A host centralized control system, this paper designs a high-speed data acquisition system based on PXI Express. In order to enable the fast acquisition system to be integrated into the HL-2A host centralized control system under the EPICS platform for centralized control and management, it mainly describes how to realize the communication between fast acquisition signal system based on C# and the upper layer OPI through the PON network under the EPICS platform. The data acquisition system hardware adopts PXIe-based chassis, embedded controller and high-speed synchronous acquisition card, which has the advantages of good mechanical encapsulation, high modularity and high sampling rate. The software adopts a measurement and control system development platform based on Microsoft. NET platform, Visual Studio development environment and Visual C# language. In this paper, the Epics C# library was studied, the EPICS Server application was developed and the remote control of the state and parameters in HL-2A host engineering system was realized. The system runs stably in the HL-2A device 2018 experiment. The result shows that the system can work stably at 10KSps sampling rate, which can better meet the needs of the device operation. This work completed the basic framework of the HL-2A Tokamak host centralized control system. And the technology and method can provide reference for the design of the next-generation device HL-2 M host centralized control system of the, laying a good foundation.
