Embodiment Construction

[0016] The method for analyzing the connectivity of urban underground comprehensive pipe network based on GIS+map database of the present invention is as follows: figure 1 shown, including the following steps:

[0017] S01, import pipeline detection and measurement result data into a graph database, and the graph database is used to store basic information of pipe points and pipeline flow direction relationship data;

[0018] Specifically, the basic information of the pipe point includes the pipe point number;

[0019] S02, the GIS system queries the pipelines and pipe points with connection relationships and the pipeline flow direction through the graph database, and loads the query results into the city map of the GIS system;

[0020] Specifically, the city map in the GIS system contains the locations of all pipe points and pipelines, and the query statement can use "match(a:Line{lineId:{'ID'}})-[:STREAM_TO*]-(b: Line) return b";

[0021] S03. According to the business re...

Abstract

The invention discloses a GIS + graph database-based urban underground comprehensive pipe network connectivity analysis method, and relates to pipe network connectivity analysis, which comprises the following steps of: storing basic information of pipe points and a pipeline flow direction relationship in a graph database, loading positions of all the pipe points and pipelines into an urban map by utilizing a GIS system, and establishing a network connectivity analysis model according to business requirements; according to the method and the system, the basic information of the pipe points and the pipeline flow direction relation data which meet the business requirements are selected through screening, the GIS renders the screening result in the city map and displays the rendering result to the user, and the problems that the transmission data volume of pipe network connectivity analysis is large and the analysis result cannot visually display the geographic position in the prior art are solved. The method is suitable for urban underground comprehensive pipe network connectivity analysis.

Description

technical field [0001] The invention relates to the analysis of the connectivity of the pipeline network, in particular to an analysis method of the connectivity of the urban underground comprehensive pipeline network based on a GIS+map database. Background technique [0002] When carrying out the simulation calculation of the pipe network, it is necessary to ensure the connectivity of the pipe network. When the scale of the pipe network is large, it will be very difficult for the design or operation and maintenance personnel to manually judge the connectivity of the pipe network. A computer method is required to analyze the pipe network. Connectivity, and intuitive display of analysis results through the human-computer interface. [0003] The existing pipe network data is stored in a relational database, and the recursive query method of SQL is used to analyze the connectivity of the pipe network. In this scheme, the database needs to be opened and closed frequently, and t...
