Pipe network data synchronization method and device

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 ...

[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 p
