基于扩展数据的给排水管网拓扑关系的构建

CONSTRUCTION OF TOPOLOGICAL RELATIONSHIP FOR WATER SUPPLY AND DRAINAGE NETWORK BASED ON EXTENDED ENTITY DATA

本文在分析AutoCAD扩展实体数据结构的基础上,结合给排水管网的管段与节点关联特点,研究提出适用于给排水管网的节点遍历查询技术,把节点信息以稀疏矩阵三元组格式存储在管段扩展数据中,通过派生成邻接矩阵,实现了自动构建给排水管网拓扑关系。

Based on section and nodes in the analysis of extended entity data applied in AutoCAD, combining the correlation of pipe water supply and drainage network, a node ergodic query technology for water supply and drainage network was purposed in this paper. The technology can construct topological relationship for water sup- ply and drainage network automatically based on derivation of adjacency matrix through storing nodes information in the form of spare matrix triples in extended pipe section data.
