摘  要:
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。

摘  要:
Based on the analysis of extended entity data applied in AutoCAD,combining the correlation of pipe section and nodes in 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 supply 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.
