摘要
从铁塔三维模型*.mod文件可以获取铁塔的尺寸、节点坐标、杆件信息、挂点类型和位置信息,但无法获取挂点的构造信息以及挂点与绝缘子串的匹配关系。基于挂点模型需表达的信息,分析挂点数字化模型的特征,提出一种全面表达挂点信息的方法和数据结构,并通过*.xml文件记录。*.xml和*.mod文件相结合,组成包含铁塔挂点信息的数字化模型。最后基于自主开发的铁塔三维建模软件,以常用铁塔为例建立挂点的三维数字化模型,并进行应用测试。
The dimensions、node coordinates、member information and position can be obtained from*.mod files of tower model.However,the constructional details and the relationship between hanging points and insulator strings can’t be obtained.In this paper,the characteristic of hanging point digital model is analyzed based on the information it wants to express.And then,a method which can express the hanging point’s information completely and a data structure are declared.The information are recorded by*.xml files.The digital model of tower hanging point is composed of the cooperation of*.xml and*.mod files.In the last part,a tower modeling software is used to create a typical example of tower hanging point.
