[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. The key technology of GIS is to simulate and analyze the physical laws of the real world by combining the geo-spatial data and some mathematical methods and models. The powerful spatial analysis ability of GIS is embodied in the management of urban underground pipeline. The spatial analysis functions of underground pipeline, such as cross-section analysis, longitudinal section analysis, connectivity analysis, burst analysis and gate analysis, are realized through development. Provide decision support for urban underground pipeline planning and management, structure optimization and accident handling.
