分布式测控网络系统EFMS模型研究

Research on the EFMS Model of Distributed Measurement and Control Network System

为了对现实世界的分布式测控网络系统进行理论分析,克服在实际应用中缺乏一种高度概括和抽象的模型用于分析指导、进行形式化描述的缺点。提出了一个基于实体、作用关系、消息、服务四要素的分布式测控网络系统数学模型———EFMS(Entity,Function,Message,Server)。本文从理论抽象的角度分析了四要素之间的关系,对系统的关键要素实体进行了定义和分析,并用成熟的Petri Net理论对数学模型的实体及其所描述的分布式测控网络进行了分析。理论分析表明,EFMS数学模型的建立,对分布式测控网络的分析具有概括、抽象、可分析、可指导的特点。

To analyze the Distributed Measurement and Control Network System（DMCNS） in the real world theoretically and overcome the disadvantages, where a high - general and abstract model is lacking for the analysis, guidance and visualized description, a mathematics model was proposed, which based on the four crucial elements of entity, function, message, server. In this paper, the relationship between the four crucial elements was analyzed with the theoretical abstract and the entity in the network was defined. The further analysis and study about the model＇ s entity and its distributed measurement and control network can be achieved with Petri net. The theory analysis suggests that this model have general, abstract, analyzable and guidable characteristic for analyzing distributed measurement and control network.
