基于可扩展架构的SVG图形系统的设计与实现

Design and Implementation of SVG Graphics System Based on Extensible Architecture

着重阐述了以可缩放矢量图形(SVG)为核心的可扩展架构的WEB图形的设计和实现技术,研究和建立了基于SVG标准的电力系统的图元库和统一的SVG图形发布格式。研发应用了跨语言接口调用的技术和跨语言结构化消息通信机制,研发应用了以服务器推送技术实现WEB画面数据异步通信机制。基于SVG和可扩展的WEB图形系统,有效解决了模型信息动态刷新时对实时性要求高的问题,提升了WEB图形应用于电网运行控制系统的水平,并在实践中得到了应用。

The paper emphatically elaborated the design and implementation technology of WEB graphics based on extensible architecture with SVG （Scalable Vector Graphics） as the core. To realize the technology, power system graphics library and unified SVG graphics publishing format were studied and set up based on the SVG standard. Besides, the R＆D applied interface call technology and structured message communication mechanism across different languages. What＇s more, asynchronous communication mechanism of WEB graphical data was achieved based on server pushing technology. The SVG and scalable WEB graphics system help effectively solve the problem of strict requirement for real-time performance when the model information is dynamically refreshed, improving the level of WEB graphics applied to power grid operation control system. Now the SVG and scalable WEB graphics system has been applied in practice.
