| 摘 要： | 应用模板数据库的方法,进行工程CAD管网拓扑建模.通过将工程对象抽象为很多具有各自特征的拓扑结构模板,建立拓扑模板数据库.在模板数据库基础上设计了一种松耦合的3层体系结构的工程CAD管网建模系统.此体系结构包括:用户层、库管理层、数据层.库管理层能够对拓扑模板进行方便快捷的管理、扩展,从而可以高效地建立和维护管网模型的拓扑结构;数据层提供统一的数据接口,使得不同领域之间可以共享拓扑模板数据.系统的层次结构分明,系统模块之间的依赖关系低,并且易于实现.采用本系统能够大大提高管网模型的建模效率和兼容性.

| Abstract: | Topological pipe-net models of engineering CAD were established using templates data library.The topological templates data library was constituted of many topological models each of which was abstracted from engineering object and had its unique characters.The loosely coupled three-tier architecture system that was applied to model pip-net models of engineering CAD was designed based on topological templates data library.The system included three layers: user layer,templates data library management and dat... |
