【摘要】 针对SCADA系统中突发信息的传输处理问题,利用发布订阅的消息机制提出了一种基于监听代理的柔性回调方法。对突发信息被动处理带来的问题进行了描述,然后利用消息中间件与回调策略,并与组件技术进行融合封装,建立了松散消息交互的柔性SCADA回调框架。在系统实现上,综合运用了二级缓存和消息监听代理等技巧。利用工程算例对突发信息的柔性处理系统进行了测试研究,结果表明:相比传统轮询方式,柔性回调技术可使SCADA系统对突发状态变位信息的调用效率提高2个数量级以上,为监控应用集成提供了一种高效处理数据的新方法。更多还原

【Abstract】 In order to resolve suddenly triggered information transferring and processing problem of SCADA system,a flexible callback method is proposed based on listener agent by using publisher and subscriber message mechanism.Some problems are described that suddenly triggered information is passive processed,then integration encapsulation of components is completed which uses message middleware and callback strategy,and loosely coupled flexible SCADA callback framework is established.In new system implementation,comprehensive skills of two-layers cache and message listener agent are used.Compared with traditional polling way,engineer example test results indicate that the new callback technology can improve efficiency by two orders of magnitude,and provide a new efficient data processing method for monitoring application integration.更多还原
