摘　　要：针对分布式调度监控应用信息处理量大,易导致信息延迟的问题,利用报童模型及其发布订阅消息通信机制,提出了一种基于报童收益机制的分布式监控应用信息发布订阅方法。设计了GOOSE信息发布订阅消息交互模式,并建立信息流发布订阅报童模型,通过蒙特卡洛方法进行信息交互模拟研究,结果表明:信息流延时小于4 ms的概率为97.43%,保证调度监控系统的实时性。以分布式调度监控系统为例,进行信息流发布订阅报童收益模型的验证,效果良好,为分布式自动化监控系统批量实时信息交互处理提供了一种更优化的方法。Due to huge amount of distributed dispatching monitoring application information （DDMAI）, liable to cause information process delay, using newsboy model and publish/subscribe message interactive model, a publish/subscribe method of DDMAI based on newsboy earning mechanism was put forward. Publish/subscribe message interactive model of GOOSE information was designed, publish/subscribe newsboy model of information flow was established with Monte Carlo method, and information interactive simulation was researched. Results show that the probability of information flow delay less than 4ms is 97.43%, therefore real-time performance of dispatching and monitoring system is ensured. Taking distributed dispatching and monitoring system as example, the publish/subscribe newsboy earning model of information flow is verified, the result is satisfactory, for distribution automation monitoring system, an optimization method of real-time information interactive processing is provided.
