A pipe network data synchronization method and device

Abstract

The embodiments of the present invention provide a pipe network data synchronization method and device, including: when the original pipe network and the new pipe network are synchronized for the first time, the equipment type information in the original pipe network is synchronized to the classification metadata table of the new pipe network, and the original The pipe network field information of the pipe network is synchronized to the equipment field metadata table of the new pipe network; the spatial data and attribute data of the pipe point elements in the original pipe network are copied to the pipe point table of the new pipe network, and the original pipe The spatial data and attribute data of the pipe segment elements in the network are copied to the pipe segment table of the new pipe network; the topology information of the new pipe network is maintained according to the topology information of the original pipe network; when the original pipe network and the new pipe network are synchronized multiple times, the original pipe network Change data in the network, and perform incremental synchronization on the new pipe network. When the original pipe network data changes and requires two or more synchronizations of the new and old pipe network data, only the changed data in the original pipe network can be synchronized to the new pipe network to avoid repeated synchronization of unchanged data.

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 ...

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
