基于SVG和持久框架的SCADA图库一体化配置系统

SCADA graph-database configuration system based on SVG and persistence framework

针对数据采集与监控(SCADA)系统工程配置困难的问题,采用可伸缩矢量图形(SVG)作为监控画面的图形格式,基于SVG的Batik组件开发包和Hibernate持久框架,设计了一套SCADA图库配置系统。在公用信息模型的基础上,提出SCADA实时数据的模库同步思想,设计了"及时同步"和"定时同步"2种同步方式,并实现了电力设备实时数据库对象/关系混合模型。采用SVG描述的电力设备图元与实时数据模型进行合并,达到了图库属性同步配置和样式关联的效果。通过绘图平台、图元库和图库同步3个模块的配合,完成了SCADA图库的一体化。

For engineering configuration,a SCADA graph-database configuration system is developed,which takes SVG as the graphic format and applies Batik package and Hibernate persistence framework. Model -database synchronization of SCADA real- time data is proposed based on common information model. Two synchronization modes of ＂in-time synchronization＂ and ＂cyclic synchronization＂ are designed and the object/ relation model of power equipment is achieved. The SVG- described power equipment graph elements and the real- time data model are merged to reach the effect of synchronized attribute configuration and associated style. SCADA graph- database integration is completed by the cooperation of drawing platform, graphic element library and graph-database synchronization.
