Research on electric power project cost estimation system based on GIS

针对目前地理信息系统应用于电力工程预算存在不能设计或修改电网图等不同程度的缺陷,提出一种基于GIS的电力工程造价估算系统,以解决现有的电力工程造价估算准确度低、自动化程度弱的问题。该系统使用面向对象技术与集成组件式GIS,构建系统核心和用户界面采用MapObjects与.NET平台,并运用Oracle数据库管理远程数据,Access数据库管理本地属性数据,从而有机结合工程中各设备的图形和属性数据,实现工程造价估算的规范化与自动化。最后对系统进行了实现验证,确保了电力工程造价估算的准确、高效。

As the current geographic information system(GIS)applied to the electric power engineering budget can′t design or modify the power grid graph and has other different levels of defects,a GIS-based electric power engineering cost estimation system is proposed to improve accuracy and automation degree of the available electric power engineering cost estimation.The object-oriented technology and integrated component GIS are used in the system.The MapObjects and.NET platform are adopted to construct the system core and user interface.The Oracle database is employed to manage the remote data,and the Access database is adopted to manage the local attribute data,so that the graphics and attribute data of each device in the project are combined to realize the standardization and automation of the project cost estimation.The system was verified with an experiment to ensure the accurate and efficient estimation of the electric power engineering cost.
