HL-2A装置EPICS过程变量管理自动化系统

Management automatic system of EPICS process variable on HL-2A tokamak

通过分析子系统接入EPICS平台时大量的数据定义以及数据转换问题,研究了EPICS IOC数据库构成和EPICS数据组成结构。采用基于ASP.NET构架的C#编程技术实现了EPICS过程变量(PV)管理自动化系统,并提供相应的操作界面。该系统解决了IOC PV信息收集与数据保障的问题,实现了PV的批量存储、权限管理、历史查询和实时更新等功能。

Through the analysis of the problem that a large number of data need to be defined and converted when subsystems access EPICS platform, the structure of EPICS IOC database and data structure were researched. Management automatic system of EPICS process variable based on ASP.NET and C#, is developed successfully with a corresponding interface. This system solved the problem of IOC PV information collection and data security, implemented the bulk PV storage, PV rights management, record query and real-time updates, etc.
