【摘要】：21世纪,信息化技术的应用已经得到了非常深入的普及。在信息化发展的浪潮下,城市的供水企业作为一个传统的公共资源提供企业,顺应了时代的潮流,进行了信息化的改革和发展。同时,供水行业由于行业的特殊性,需要对复杂且庞大的地下供水管网进行管理。基于以上的基本条件,对供水管网等进行了研究,提出了供水管网信息管理信息系统方案,并设计和实现了应用系统。就目前的行业现状分析,依然有许多城市的供水企业采用传统的手工图纸管理的方法来进行地下管网的管理,这种传统的管理方法不仅存在着管理效率低,出错率高的缺点,还面临着由于城市的建设和发展,地下管网越发复杂,导致管理成本大幅度上升的情况。同时,随着地理信息系统(GIS, Geographical Infomation System)理论的发展和越来越多的地理信息系统项目的实施。使用地理信息系统技术来构建城市供水信息系统具有高度的契合度。其自身的工具方法、功能模块、数据定义非常适合存储和管理供水管网数据。通过建立基于地理信息系统的城市供水信息系统从而提高供水企业的服务水平和服务质量已成为解决供水行业管理困境的最有效途径。在基于GIS的供水信息系统研究和开发过程中,综合运用了空间数据库技术、信息系统开发技术、GIS组件开发技术、计算机网络技术和给排水技术,并结合了供水企业业务部门的实际业务需求。通过建立地理信息数据库、管网信息数据库、业务管理数据库,并在这个基础上完成了基于GIS的城市供水信息系统的开发。系统建设严格按照软件工程建设的相关要求和规范,并且基于实用性、可靠性、完备性、科学性、规范性、经济性、可操作性、可扩展性和开放性的建设原则进行开发。完成后的系统,不仅在需求上满足业务部门的需求,同时在技术上符合当下先进的软件开发标准。系统具备较为完善的查询功能和分析功能。实现供水管网的信息化管理,提高了管理效率和管理水平。该系统具有数据管理、可视化管理、业务管理等多方面的功能,并与其它系统相互兼容,保证数据信息的共享。同时,在系统的设计和实现过程中,通过GIS系统特有空间数据处理和展示方法实现了工程管理应用、SCADA应用,通过图论的广度优先算法实现了供停水范围分析应用,通过一些特有的算法理论和统计理论的实现了分区计量应用和管线横剖面分析等系统模块。提高了系统的实用性,使供水业务和地理信息系统更加紧密地联系在一起。为城市供水管网的管理提供了完成的解决方案和项目案例。
[Abstract]:In 21th century, the application of information technology has been deeply popularized. Under the tide of information development, urban water supply enterprises, as a traditional public resource provider, conform to the trend of the times. At the same time, because of the particularity of the industry, the water supply industry needs to manage the complex and huge underground water supply network. Based on the above basic conditions, the water supply network is studied. The information management information system scheme of water supply network is put forward, and the application system is designed and implemented. There are still many urban water supply enterprises using the traditional manual drawing management method to manage the underground pipe network. This traditional management method not only has the shortcomings of low management efficiency and high error rate. It is also facing the situation that the underground pipe network is becoming more and more complicated because of the construction and development of the city, which leads to a big increase in the management cost. At the same time, With the development of GIS and Geographical Infomation system theory and the implementation of more and more GIS projects, it has a high degree of conformity to use GIS technology to construct urban water supply information system. Function module, The definition of data is very suitable for storing and managing the data of water supply network. To improve the service level and service quality of water supply enterprise by establishing city water supply information system based on geographic information system has become the solution to the management of water supply industry. In the research and development of water supply information system based on GIS, The spatial database technology, information system development technology, GIS component development technology, computer network technology and water supply and sewerage technology are used synthetically. The development of urban water supply information system based on GIS is completed on the basis of pipe network information database and business management database. The system construction is strictly in accordance with the requirements and specifications of software engineering construction, and based on practicability and reliability. Complete, scientific, normative, economic, operational, extensible and open construction principles are developed. The completed system not only meets the needs of business departments, At the same time, it conforms to the current advanced software development standard technically. The system has more perfect query function and analysis function. It realizes the information management of water supply network, and improves the management efficiency and management level. The system has data management. Visual management, business management and other functions, and compatible with other systems, to ensure the sharing of data and information. At the same time, in the design and implementation of the system, Through the special spatial data processing and display method of GIS system, the application of engineering management is realized, and the scope analysis of water supply and shutdown is realized by using the breadth-first algorithm of graph theory. Through some special arithmetic theory and statistics theory, the system modules such as divisional metering application and pipeline cross-section analysis are realized, and the practicability of the system is improved. Makes water supply business and GIS more closely linked. Provides completed solutions and project cases for the management of urban water supply networks.
