Research On The Construction And Technology Of The Integrated Management System Of The Underground Pipeline In Beijing

With the deepening of the urban fine management,the management of urban infrastructure is no longer limited to urban construction,roads,bridges and other ground infrastructure,but also a variety of underground pipeline network management,especially in recent years,the urban underground pipeline accidents occur,the underground pipeline management level is not high,the problem of inadequate measures,data sharing difficulties and other issues highlighted.Therefore,it is urgent to establish a comprehensive management information system of underground pipeline.The Beijing city underground pipeline census carried out of it,combined with the actual work,on how to carry out the underground pipeline data acquisition,storage,construction of integrated management system,and the data management of the application content were research and practice.1.The technology of spatial database establishment of underground pipeline data maintenance and management system,completed the construction design and management of basic information database,in order to achieve the goal of "the city's underground pipeline data unified management".2.Through analysis technology based on 3D underground pipe space Citymaker technology,intelligent data processing technology analysis and 3D analysis system of underground pipe network research and development,to achieve the integrated management system of the urban underground pipeline,three-dimensional database linkage,and truly realize the integration of 3D data.3.Based on SOA architecture construction of the guiding ideology of underground pipeline sharing application system and the realization of the government departments,industry executives and data maintenance of the interconnection between departments.At the same time to achieve the positioning line,query pipeline,pipeline statistics,spatial analysis,underground service sharing,the application of three-dimensional pipeline service monitoring function,in order to achieve the city's underground pipeline information sharing,for urban planning,construction,management and emergency rescue to provide services.4.Research of GIS component development technology to realize the wholesystem based on component,modular programming and design and development of object oriented.In order to ensure the system have good scalability and adapting to changes in demand,easy to upgrade and expand.Based on the establishment of census database and comprehensive management system,the comprehensive management of census data in the test area,the dynamic update,and the sharing of the data are realized.
