基于MapObjects的配电网信息管理系统开发

Development of distribution network information management system based on MapObjects

基于地理信息系统(GIS)组件MapObjects(MO),结合面向对象与重用技术,提出可移植的、面向对象的电力GIS图形建模方法。详细论述了图形建模设计中的MO基本符号类、电力元件符号类及结构;数据建模中的空间数据库、属性数据库的设计;MO中地图符号的绘制方法。以实例介绍了该方法所开发的图形系统,说明该系统具有良好的应用前景。

Based on GIS module MO（MapObjects）and combined with the object-oriented and reiteration technologies,a method of transplantable,object-oriented,electric GIS map symbol data modeling is presented. The MO basic symbol class and electric element class are described in detail,as well as their structures. The design of spatial database and attribute database and the way to draw map symbols in MO are presented. Example shows the graphical system developed and proves it applicable.
