配电GIS系统中复杂设备接点的设计和实现

DESIGN AND IMPLEMENTATION OF COMPLEX EQUIPMENT JUNCTION IN DISTRIBUTION GIS

配电网中的复杂设备,由于内部拓扑结构复杂,可用几何网络中的复杂接点对其进行描述,但ArcGIS并没有提供可供生成的复杂接点模型。基于Geodatabase模型,针对配电网复杂设备的结构特点,利用UML建模语言和ArcGIS提供的Case工具,设计电缆分接箱复杂接点对象模型并实现了该复杂接点。这种方法使复杂设备的图形显示更加直观、易于操作,且适合于描述配电网的拓扑结构。

In distribution networks, because its inner topology structure is complicated, the complex junction in geometry network can be used to describe the complex equipment of the networks. However ArcGIS does not provide the model for generating the complex junction. In this paper, we took the Geodatabase model as the basis, according to the structure character of the complex equipment in distribution networks, designed the object model of CableBraehBox complex junction and realised this complex junction using UML （ Unified Modelling Language） and Case （Computer-assisted software engineering） tools which is provided by AreGIS. This method makes the complex equipment＇s graphical display more directly visualised and easy to revise, and is more appropriate to describing the distribution networks topology structure .
