摘　　要：针对分布式监控应用中SVG界面的实时数据交互慢和实时信息处理效率低的问题,研究了一种配电网分布式监控SVG界面刷新的实时Ajax数据引擎技术方案。从实时交互信息、实时Ajax数据引擎和可伸缩矢量图动态刷新的操控,到开关量和模拟量数据结构设计,给出了Ajax数据引擎和SVG图元局部刷新的关键实现方法。以配电网的调度监控界面为算例,进行模拟量和状态量的交互测试,实现了监控界面的SVG局部更新。对图元数据的测试表明,SVG界面刷新延时约为百毫秒级,验证了实时数据引擎在分布式监控界面快速刷新处理中的有效性。In order to solve the problem of SVG interface＇s slow interaction rate of real-time data and low processing efficiency of real-time information in distributed monitoring applications, a new technology scheme for distributed monitoring SVG interface refreshment of distributed network based on real-time Ajax data engine is studied. From real-time information interaction, real-time Ajax data engine and dynamic refresh control of scalable vector graphics to structure design of switching data and analog data, the key implementation methods for partial refreshment of Ajax data engine and SVG graphic element are given. Take the monitoring interface of distribution network as an example for doing interactive tests of analog quantity and state quantity, which realize SVG partial refreshment of monitoring interface. Tests result for graphic element data show that the refresh delay of SVG interface is about one hundred milliseconds, verifying the fast refresh processing validity of real time data engine in distributed monitoring interface.
