摘要

摘要: 在开发P&ID辅助设计系统的过程中,需要表示实体间的逻辑拓扑信息.为避免引入附加抽象实体来表示逻辑拓扑信息带来的复杂性,提出以面向对象为基础将逻辑拓扑信息统一在实体本身数据结构中的方法,并介绍了从P&ID管网图抽象建立P&ID无向图模型的过程.此方法和模型在实践中取得了很好的效果.对P&ID无向图结构的特点做了深入分析,指出运用此模型建立P&ID系统的要点及运用中应注意的问题,并讨论了P&ID无向图模型的扩展.

Abstract: When developing P&ID aided design system, the logical topology information between entities needed to be represented. In order to avoid the complexity of importing additional abstract entities, a new model is designed in which the logical topology information is united to the primary entity's data structure. This model has been successfully practised. The modeling process of P&ID undirected graph model from piping network graph was presented. After analyzing the characters of P&ID undirected graph, it points out what should be paid attention to when applying the model and how to extend the undirected graph.
