地下管线是城市基础设施的重要组成部分,承载着城市规划、建设、管理的重要基础信息。针对城市管线系统难于管理的现状,对地下管线数据特征及空间数据组织、三维模型构建的原理与算法和三维空间分析进行了研究。给出了整体功能设计、总体结构设计和技术路线。使用超宽带技术对所有数据实现无线传输。 Underground pipeline is an important part of urban infrastructure, carrying an important basis for urban planning, construction and management information. In view of the status quo of urban pipeline system difficult to manage, this paper studies the characteristics and spatial data organization of underground pipeline, the principle and algorithm of three-dimensional model building and three-dimensional spatial analysis. Given the overall functional design, the overall structure design and technical route. Uses ultra-wideband technology for wireless transmission of all data.
