关于城市轨道交通运行区域三维空间基础数据库建设的研究

On the Construction of Three-dimensional Space Database for Urban Rail Transit Operation Region

阐述了为发展城市轨道交通维护保障的数字化和信息化管理而建设三维空间基础数据库的内涵、必要性和对一些重大问题的研究结果。提出了基于城市轨道交通空间基础数据库的维护保障管理信息系统的体系构架,以及对运行区域进行段落化、网格化划分为单元空间的方法。着重分析了空间数据结构与特性,以及空间数据采集技术与方法。展望了城市轨道交通空间基础数据库在发展数字城市轨道交通与企业信息化管理方面所起的重要作用。

This paper elaborates the connotation, the necessity of three-dimension space basis database construction for the digitization and informatization management of the maintenance-security for the development of urban rail transit, and the results of studies on some major issues. The author proposes the system architecture of maintenance-security management information system on the basis of space basis database of urban rail transit and the method of dividing operation regions into unit-space by sectioning and gridding operation regions. The analysis of spatial data structures and features and the spatial data acquisition technique and methods are focused on. The author also looks forward to that the space basis database of urban rail transit will play an important role in the development of the digital urban rail transit and enterprise informatizaon management.
