城市通讯管网资源GIS关键技术分析

Key techniques to urban communication pipe GIS

通讯管线资源管理是城市地理信息的重要组成部分。基于ARCSERVER平台,运用分布式技术,将传统关系型数据库所表现的管线资源信息建立成以Geodatabase为中间件的管网信息库。采用空间数据引擎,利用数据处理后的图形信息直观显示光纤及电缆的跳接状态。对光缆铺设、管线预警、电话号码查询定位和局站业务流量分析四个方面采用流动系统的动力学关系架构及网络空间数据的几何拓扑分析,进行最优路径查询统计。利用网络环境下多台计算机处理能力的集成来完成地理信息海量数据的网格计算,快速动态地提供管线监测、管网业务流操作,为管理者提供决策支持信息。

Management of resources of communication pipe is one of the most important parts in urban GIS. Based on the Arc server platform and distributed technology, the traditional Relational database of pipe network information database is transformed into the pipeline resource database with the technology of middleware-Geodatabase. Spatial data engine is also used to display the states of terminating fiber optic cables and optical cable transfer splicing operation as well based on the processed graphic data. With dynamic flow system and logic topology rules, the best path and statistic inquiries are implemented to those aspects including eontra posing cable installation, accident forecast, query orientation with telephone number, and traffic analysis. It helps the governor with making decisions efficiently in monitoring and inspecting the pipe network services.
