摘要
针对数据采集与监控(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和回调策略,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。系统的实现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。
In order to resolve the transfer and processing problems of suddenly triggered information with the SCADA system,a flexible callback method is proposed based on the listener agent using the publish/subscribe message mechanism.Some problems brought about by passive processing of suddenly triggered information are described.Then a loosely coupled flexible SCADA callback framework is developed using message middleware and callback strategy while performing integration encapsulation of components.In implementing the new system,comprehensive skills of two-layers cache and message listener agent are used.Compared with the traditional polling way,engineering example test results show that the new callback technology can improve efficiency by two orders of magnitude and provide monitoring application integration with a new method for highly efficient data processing.
