Problems solved by technology

[0003] At present, there are two main methods to establish the pipe network model: one is to store the graphics and attribute data separately, and connect them through the keywords of the attribute fields. The topological relationship between them cannot be effectively managed; the other is to use a hierarchical model to manage attribute data, graphic data and topological relationship data in a unified manner, such as the ARCGIS pipeline model (APDM) and the network model of MAPGIS. The shortcomings of this type of pipeline network model Due to the immobilization of the attribute data structure and the large number of data layers, it is difficult to realize the decision-making analysis and comprehensive management of complex pipe networks
In addition, the ARCGIS Pipeline Model (APDM) and the network model of MAPGIS are closely connected with the data management methods of its own software platform, lacking unity and interoperability support, which is not conducive to information integration and function sharing between geographic networks

Abstract

The invention relates to a method and a system for establishing a pipe network model. The method include: defining metadata of a pipe network model; according to the metadata characteristics of the pipe network model, establishing a conceptual model and describing the model in UML form, wherein the first-level entity of the conceptual model is defined as a pipe segment entity, a pipe point entityand a pipeline entity; carrying out spatial database instantiation; analyzing the UML description of the pipe network conceptual model, and transforming it into a geospatial data format, instantiatingpipe segment object, pipe point object and pipeline object, and constructing a pipe network model spatial database. The invention adopts a unified data organization form, realizes the integrated management of various pipeline facilities and convenient pipe network data topology maintenance, effectively reduces the layer number of data through virtual layering, and realizes the quick calling and loading of pipe network spatial data.

Description

technical field [0001] The invention relates to the technical field of urban underground pipe network planning, in particular to a method and system for establishing a pipe network data model. Background technique [0002] The underground pipe network includes water supply pipe network, drainage pipe network, electric power pipe network, gas pipe network, communication pipe network, etc., with a large amount of data, many types, and different characteristics. Various pipe network facilities are independently owned by different ownership units and governments. Establishment and maintenance, lack of unified planning in management, lack of integration means in technology, resulting in problems such as inability to guarantee data consistency among various departments, difficulty in data update, and poor current situation. A pipe network model for comprehensive data integration and sharing. The pipe network model is a network model designed for urban pipe networks, including the...
