Design And Implementation Of Urban Water Supply Network Management System Based On GIS Technology

Firstly,on the basis of analyzing the specific business requirements of urban water management departments,the use case diagram of UML technology is used to analyze the specific business functional requirements of urban water supply network system from four parts: basic data management,data view management,view query and retrieval,and pipe network accident analysis.And the non-functional requirements of the system are analyzed from three aspects: information sharing,performance requirements and security requirements.Secondly,the urban water supply network management system design,based on the analysis of the urban water supply network management system functional requirements and performance requirements,using B / S three-tier structure for the overall structure of urban water supply network management system design,and system functional structure design.And focus on the urban water supply network accident analysis function of the traditional burst pipe shut-off algorithm research,and in view of its problems,the improved breadth-first search algorithm to achieve urban water supply network burst accident disposal research.Finally,based on the three-dimensional database and the characteristic attribute database of the pipe network management system,this paper focuses on the development and implementation of the four specific functional modules of the urban water supply pipe network management system,including basic data management,data view management,view query and retrieval,and pipe network accident analysis,so as to achieve the accuracy.
