This paper presents the architecture and the implementation of the upgraded Experimental Advanced Superconducting Tokamak (EAST) Poloidal Field Power Supply (PFPS) monitoring system. To meet the requirements of EAST long pulse discharge, the monitoring system has been upgraded based on experimental physics and industrial control system (EPICS) and MDSplus. It provides an integrated management of supervision, data acquisition and real-time control. The program is flexible and portable, which improves the system performance. The I/O interrupt mechanism of the device support module is used to read the updated data, which reduces the network communication load. Asynchronous Driver Support (AsynDriver) is used to develop the device's specific interfacing code for the DAQ card driver, simplify writing of drivers and make the program more reliable. The HMI is developed using Control System Studio (CSS). During the experiment, the collect data is stored in the archiving system from PFPS system and sent to the MDSplus data server at the same time, so that the operator can view and analyze the online data and offline data. The upgraded monitoring system provides a general design scheme, which can be well integrated into the control system. The experimental results show the system realizes the remote operation and monitoring of equipment of PFPS and provides a friendly human-machine interface, supports multiuser operation.

EAST极向场供电监控系统升级

本文介绍了升级后的实验性先进超导托卡马克(EAST)极向场电源(PFPS)监测系统的架构和实现。为了满足EAST长脉冲放电的要求,基于实验物理和工业控制系统(EPICS)和MDSplus对监测系统进行了升级。它提供监控、数据采集和实时控制的集成管理。程序灵活、可移植,提高了系统性能。利用设备支持模块的I/O中断机制来读取更新的数据,减少了网络通信负载。异步驱动支持(AsynDriver)用于开发设备专用的DAQ卡驱动接口代码,简化驱动程序的编写,使程序更加可靠。HMI 是使用 Control System Studio (CSS) 开发的。实验过程中,采集的数据从PFPS系统存储到存档系统中,同时发送到MDSplus数据服务器,以便操作人员查看和分析在线数据和离线数据。升级后的监控系统提供了通用的设计方案,可以很好地集成到控制系统中。实验结果表明,该系统实现了PFPS设备的远程操作和监控,提供友好的人机界面,支持多用户操作。
