【摘要】 城市供水管网地理信息系统(Water Supply Distribution Network GIS,WSDNGIS)是利用GIS技术,在建立管网空间、属性数据库的基础上,管理供水管网空间和属性信息的综合信息系统,为供水规划、设计、抢修和图籍资料的管理提供强有力的科学决策依据,实现分析决策的全计算机操作,提高供水管理的效率、质量和水平。系统的建立是城市供水信息化的发展要求。 系统包括五个子系统:1.数据管理子系统;2.查询统计子系统;3.管网管理子系统;4.事故处理子系统;5.系统维护子系统。数据管理子系统提供管网空间数据和属性数据及背景地理数据的输入、输出和更新功能。查询统计子系统提供按自定义条件进行综合管网设备信息查询的功能,查询的结果可生成报表打印输出。管网管理子系统提供对管网的日常维护功能,包括对管网图的分层管理和无延时浏览;对指定管段生成横断面、纵剖面图辅助设计等。事故处理子系统对管网的突发爆管事件、施工关阀及阀门检修提供辅助决策。系统维护子系统进行整个系统的维护,包括系统数据库的备份、数据字典的管理及用户权限密码管理等。 系统选用组件式地理信息系统软件——MapObjects与VB编程语言相结合,实现对管网信息的管理和分析,采用SDE技术基于GeoDatabase概念组织管理数据,实现空间数据与属性数据一体化无缝存储。 本文通过对供水管网地理信息系统(GIS)的设计与实现,探讨了MIS技术、数据库技术、GIS技术、网络及多媒体技术等在供水管网日常管理中的应用。更多还原

【Abstract】 Urban water supply distribution network geographic information system (WSDNGIS) is a compositive information system which uses GIS technology to manager water supply distribution network spatial and attribute data based on establishing spatial and attribute database. It is necessary for modernization city to establish a WSDNGIS to enhance management and efficiency of water supply distribution network.To develop WSDNGIS, Visual Basic and MapObjects which is a component GIS software are adopted to manage and analyze pipe network information. Spatial data and Attribute data are stored in the same database, which is managed by SDE technology based on GeoDatabase concept.WSDNGIS is divided to five subsystems: I. Data Management subsystem; II. Query Statistics subsystem; III. Pipe Network Management subsystem; IV. Crash Handling subsystem; V. System Maintenance subsystem. The main function of data management subsystem is to manage database, such as data input, data output, data update and so on. The main function of query statistics subsystem is to query and statistic pipe network information and outcome can be printed as report forms and statistics figures. The main function of pipe network management subsystem is to manage pipe network, such as managing drawing on layers, drawing section of pipe and so on. The main function of crash handling subsystem is to provide efficient and scientific decision-making for Valve-turnoff Analysis. The main function of system maintenance subsystem is to provide system maintenance, such as system database backup, data dictionary management, users’ cipher and purview management and so on.A probe into application of MIS technology and database technology and GIS technology and network technology and Multi-Media technology in water supply distribution network’s daily management is presented by design and implement of water supply distribution network geographic information system in this paper.更多还原
