摘要
本文利用AutoCAD高效精确绘图功能和VBA开发技术,在分析*.inp文件结构的基础上,采用对象遍历查询手段,利用二维数组存储方式,构建管段与节点拓扑关系的三元组表,获取管段长度和起止点的XY坐标,准确转换成*.inp文件。采用这种方式把管网几何信息和拓扑关系导入到EPANET中,解决了EPANET建模困难的问题,实现了给水管网从AutoCAD到EPANET的有效导入,保证了管网模型在AutoCAD与EPANET平台上的信息统一,提高了给水管网水力分析的效率。
This article utilized the efficient and accurate drawing function of AutoCAD and VBA development technology,based on the analysis of the*.inp file structure,object traversal query method and a two-dimensional array storage method were used to construct a triple table of the topological relationship between pipe segments and nodes,obtain the XY coordinates of the pipe segment length and the starting and ending points,accurately converted into a*.inp file.By using this method to import the geometric information and topological relationships of the pipeline network into EPANET,the difficulty of EPANET modeling was solved,and the effective import of water supply network from AutoCAD to EPANET was achieved,ensuring the unity of information in the pipeline network model on the AutoCAD and EPANET platforms,and improving the efficiency of hydraulic analysis of water supply network.
