Problems solved by technology

[0003] At present, there are two main methods to establish a 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 MAPGIS network model are closely connected with the data management method of its own software platform, lacking unity and interoperability support, which is not conducive to information integration and function sharing between geographic networks

Embodiment Construction

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041]In the existing technology, by establishing a pipe network model, it abstracts the pipe network entities into two types: pipe points and pipe sections. The equipment types of pipe points and pipe sections are uniformly stored in the equipment classification table, and the fields contained in the equipment are stored in the equipment field tab...

Abstract

The embodiment of the invention provides a pipe network data synchronization method and device, and the method comprises the steps: enabling the equipment type information in an original pipe networkto be synchronized to a classification metadata table of a new pipe network when the original pipe network and the new pipe network are synchronized for the first time, and enabling the pipe network field information of the original pipe network to be synchronized to an equipment field metadata table of the new pipe network; copying the spatial data and the attribute data of the pipe point elements in the original pipe network to a pipe point table of a new pipe network, and copying the spatial data and the attribute data of the pipe section elements in the original pipe network to a pipe section table of the new pipe network; Maintaining the topological information of the new pipe network according to the topological information of the original pipe network; and when the original pipe network and the new pipe network are synchronized for multiple times, identifying change data in the original pipe network, and performing incremental synchronization on the new pipe network. When the data of the original pipe network is changed and secondary or repeated synchronization of the data of the new pipe network and the old pipe network needs to be carried out, only the changed data in theoriginal pipe network can be synchronized to the new pipe network, and repeated synchronization of invariant data is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and more specifically, to a method and device for synchronizing pipe network data. Background technique [0002] The pipe network model is a network model designed for urban pipe networks, including the establishment of geometric topology and logical topology rules of pipe network graphics and geographical elements, and accurately expressing various connection relationships of the physical network of the pipe network. It is the basis for establishing an underground pipe network information management system The foundation of the system provides guarantee for system data query, editing, modification, statistics and data analysis. [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 ...
