【摘要】：城市地下管线的管理是城市基础设施建设管理工作中最重要的环节之一,理解、认识并掌握城市地下管线的现状是当今城市规划、城市建设与城市管理的基本需求。城市的基础设施建设的步伐的不断加快,作为城市“生命线”的城市地下管线建设速度也随之提速,伴随而来的城市地下管线运行管理问题却愈发复杂。传统的档案式城市地下管线管理方式已经不能适应当今城市管理信息化的步伐。随着科学技术的发展,与GIS技术结合的城市地下管线信息系统是城市信息化建设的重要组成部分,其采用GIS作为主要手段科学管理各种管线信息,不仅能够实现各类管线数据的及时更新与维护,保证数据的现势性,而且能够提供准确、实时的管线信息,为城市的规划和建设提供辅助决策依据,既提高了管线管理水平,同时也为城市地下生命线的安全运转提供了技术保障。 本文依照城市地下管线相关技术规范文件,对地下管线数据进行质量控制,再根据地下管线数据的特征,对管线数据结构进行设计和优化。城市地下管线是交错有序、但又复杂缜密的,其数据属性数量众多,表达着所属管线各个详细信息。地下管线数据在地下管线勘测、数据输入等环节难免会有数据错误的发生,可能会导致地下管线在进行地理空间化时,发生坐标位置错误、属性偏差、系统无法识别等等。为了应对此类复杂情况发生,需要进行相应的地下管线数据质量控制以及检测校验。地理信息系统技术在城市地下管线中的应用,不能仅仅停留在空间信息的存储、查询、检索等,更重要的是如何利用G1S的分析、模拟、预测等功能。根据地下管线的空间分布特征,研究适合实现GIS空间分析功能的地下管线数据结构。 本文根据城市管线管理需求,研究开发基于C/S模式的城市地下管线信息系统,利用Oracle数据库作为构建城市地下管线数据库,在.NET Framework平台中运用组件式GIS理念,以ArcGIS作为GIS平台,利用其数据库工具以及二次开发组件接口进行城市地下管线信息系统的开发实现,完成本文GIS理论运用实践于城市地下管线管理中的应用研究。 本文主要研究组件式GIS技术在地下管线信息系统开发中的应用。通过对系统的需求分析,提出了系统目标、设计原则、体系结构、数据流程等。围绕组件式GIS技术展开研究和开发,并设计出系统核心功能及相应实现方法,主要包括对各种地下管线的查询、检索和数据统计、显示、输出等功能的实现。GIS的核心技术是结合地理空间数据以及一定的数学方法和模型,对现实世界的物质规律进行空间模拟和分析。将GIS强大的空间分析能力体现于城市地下管线管理之中,通过开发实现地下管线的横截面分析、纵截面分析、连通性分析、爆裂分析和关闸分析等管线空间分析功能,为城市地下管线规划管理、结构优化以及事故处理等提供相应的决策支持。
[Abstract]:The management of urban underground pipelines is one of the most important links in the management of urban infrastructure construction. Understanding, understanding and mastering the present situation of urban underground pipelines are the basic needs of urban planning, urban construction and urban management. With the acceleration of the pace of urban infrastructure construction, the speed of urban underground pipeline construction, as the "lifeline" of the city, is also increasing, but the problem of operation and management of urban underground pipeline is becoming more and more complicated. The traditional archival underground pipeline management can not adapt to the pace of urban management information. With the development of science and technology, urban underground pipeline information system combined with GIS technology is an important part of urban information construction, which uses GIS as the main means to manage all kinds of pipeline information scientifically. It can not only realize the timely updating and maintenance of all kinds of pipeline data, but also provide accurate and real-time pipeline information, which can provide auxiliary decision basis for urban planning and construction, and improve the level of pipeline management. At the same time, it also provides technical guarantee for the safe operation of urban underground lifeline. In this paper, according to the relevant technical specifications of urban underground pipeline, the quality control of underground pipeline data is carried out, and the structure of pipeline data is designed and optimized according to the characteristics of underground pipeline data. Urban underground pipelines are interlaced and orderly, but complex and meticulous. Their data attributes are numerous and express the detailed information of their pipelines. The underground pipeline data in the underground pipeline survey, data input and other links will inevitably have the occurrence of data errors, which may lead to underground pipeline in the process of geospatial, the occurrence of coordinate position errors, attribute deviation, system can not be recognized and so on. In order to deal with this kind of complex situation, it is necessary to carry on the corresponding underground pipeline data quality control and check. The application of GIS technology in urban underground pipeline can not only stop at the storage, query and retrieval of spatial information, but also how to use the functions of G1S analysis, simulation, prediction and so on. According to the spatial distribution characteristics of underground pipeline, the data structure of underground pipeline which is suitable for GIS spatial analysis is studied. According to the requirements of urban pipeline management, this paper studies and develops the urban underground pipeline information system based on C / S model. Oracle database is used as the construction of urban underground pipeline database. In the .NET Framework platform, the concept of component GIS is used, and ArcGIS is used as GIS platform. The application of GIS theory in urban underground pipeline management has been accomplished by using the database tool and secondary development component interface for the development and realization of urban underground pipeline information system. This paper mainly studies the application of component GIS technology in the development of underground pipeline information system. By analyzing the requirements of the system, the paper puts forward the system objectives, design principles, architecture, data flow and so on. The research and development of component GIS technology are carried out, and the system core functions and corresponding implementation methods are designed, including query, retrieval, data statistics and display of various underground pipelines.
