环状给水管网关联矩阵的建立

Construction of Incidence Matrix in the Annular Water Supply Networks

利用AutoCAD VBA开发技术,定义环状给水管网的管段实体扩展数据结构,借助遍历查询手段构建管段与节点关系的峰矩阵,转换峰矩阵为邻接矩阵,自动快捷地为管网系统水力分析做好准备。

Augmenting data structure of pipe entity in annular water supply network is defined in this paper. The peak matrix of rela-tionship between tube section and node is constructed by means of the ergodic searching method. Then peak matrix is converted adja-cency matrix. It is ready for pipe network hydraulic analysis automatically and fast.
