【摘要】 现代城市供水管网已经构成了规模巨大而复杂的管线网络系统,每个城市都累积了一大批供水管网设计、施工、竣工的图件和表册资料。长期以来,各城市的供水部门都沿用人工方式来管理这些资料。随着经济的飞速发展,这种人工管理模式很难满足实际需要。另一方面,现有供水管线的资料残缺不全,且精度不高或与现状不符。管线在建设施工中时常被挖断或挖坏,造成停水、爆管等严重事故。为提高对供水管线的管理水平,供水部门希望建立供水管网信息管理系统。将GIS(Geographical Information System)技术应用于我国城市供水管网的管理之中,是实现供水管网科学化和自动化管理的重要手段。本课题的目标是以ArcInfo为平台,基于OCX技术采用Visual Basic 6.0构建实用的城市供水管网GIS系统。本文首先介绍了城市供水管网GIS的背景知识以及本课题所涉及的基础理论,根据系统总体目标及设计原则,以及系统所要具备的项目技术内容,结合ArcInfo的二次开发平台的特点,给出了系统的整体架构,提出了系统的总体设计方案,重点对爆管分析模块和纵断面分析模块进行了深入细致的分析和设计。对于爆管分析,提出一种新的基于动态分段技术的网络模型;对于纵断面分析,设计了专门的有利于生成纵断面图的数据结构。最后,在上述所述基础上,给出了系统的具体实现。更多还原

【Abstract】 Current urban water supply network has formed a huge-sized and complicated pipeline system,so in each city there are a large group of maps and statistical forms datum for the design,construction and completion for a water supply network. For a long time,these datum in urban water supply departments are administered by means of manpower. With the rapid development of economy,the management mode of the traditional manpower can hardly meet the need in reality. And in other hand,files for the existing water supply pipelines are not complete,accurate and accord with the reality. Pipelines often be dig broken or damaged,which results to severe accidents such as water stoppage or pipe explosion etc. To improve the management level for the pipelines,water supply departments hope to establish water supply information management systems. Applying GIS(Geographical Information System)technology to the urban water supply network administration,is an important way to realize the pipeline scientific and automatic administration.This project aims at design and development of GIS on urban water supply network by using Visual Basic6.0 on the basic of ArcInfo and is supported by OCX. The thesis begins with background knowledge introduction for the GIS on urban water supply network and the relevant basic theories. According to the system general goal,design principles,and project technical contents,at the same time combining characteristics of ArcInfo second-development platform,the paper presents system integrated architecture,and puts forward the system comprehensive design scheme. The emphasis is put on a deep and particular analysis & design of pipe-broken analysis module and section analysis module. For pipe-broken analysis, a new network model is presented based on dynamic segmentation technique. For vertical section analysis, a special data structure good for creating vertical section figure is designed. Finally,the system is implemented basing on the previous detailed work.更多还原
