Research On Data Model For Hydraulic Pipeline System

Pipeline water transport is one of the efficient water delivery methods among larger areas,and it is increasingly used in the construction of actual projects,which largely alleviates the problem of lack of regional water resources that restricts socioeconomic development.The data of the water transmission pipeline project is the core of the digital simulation of the water transmission pipeline.The data of the water transmission pipeline project involves multiple fields and departments,forming separate scattered islands.The integrated management and unified use of these data is an important goal for realizing the informationization of the water pipeline engineering.How to construct a data model of water transmission pipelines is the basis for comprehensive management and unified use of water pipeline data.In this paper,the relevant parameters of the water pipeline are analyzed in detail from the point of view of hydraulic calculation,and the data of the major equipment and facilities of the pipeline are explained in detail according to the relevant national standards.Based on the Geodatabase geographic data model and GIS-related technologies,the geographical data model of the pipeline project is carried out.based on RDBMS modeling the related entities of the water pipeline,based on the model,designed and developed a data management system for the water pipeline.The main research is as follows:(1)This article describes the characteristics of the water transmission pipeline project,introduces the main components of the project and the required data and data characteristics.It takes the pressure check of the water transmission pipeline and equipment which obtains a series of required parameters through hydraulic calculation as the core and consults related national standards and regulations,the purpose is to get a series of data sets of water pipeline engineering.(2)On the basis of the above data analysis,combined with the advantages of Geodatabase geographic data model and the characteristics of water pipeline engineering,a geographic data model of water transmission pipeline was established.Based on the E-R model,the hydraulic calculation data model of water transmission pipeline was established,and the database logic design model was given.(3)Based on the data model of hydraulic pipeline,a detailed analysis of the functional requirements of the data management system of the water transmission pipeline was made,and the overall architecture of the system and the information technology adopted to explain it were proposed.Based on the model above,the paper also makes a detailed database design for the data management system of the water pipeline,establishes a detailed data table,and implements the data management system of the water pipeline on the basis of the previous work.
