Method and system for detecting pipe diameter connection state among pipelines

Abstract

The invention relates to a method and system for detecting the pipe diameter connection state among pipelines. The method comprises the following steps: acquiring a plurality of target pipelines communicating with a to-be-measured pipe point; acquiring the flow direction category, pipeline category and pipe diameter of each target pipeline; according to the flow direction category and the pipe diameter of each target pipeline, determining the outlet pipe diameter sum of the to-be-measured pipe point and the inlet pipe diameter sum of the to-be-measured pipe point; and according to the pipelinecategory of each target pipeline, the outlet pipe diameter sum of the to-be-measured pipe point and the inlet pipe diameter sum of the to-be-measured pipe point, determining the pipe diameter connection state among the communicating pipelines of the to-be-measured pipe point. According to the method and system for detecting the pipe diameter connection state among the pipelines provided by the invention, the accuracy in detecting the pipe diameter connection state among the pipelines is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for detecting the connection state of pipe diameters between pipelines. Background technique [0002] Urban underground comprehensive pipeline is an important part of urban municipal engineering. In view of the fact that the existing underground pipelines are various and complex, and they are distributed underground in a three-dimensional cross network. At present, underground pipeline data is often converted into spatial data by using GIS technology and then stored and managed. Therefore, the correctness of the spatial logical relationship of underground pipelines is an important criterion for judging the quality of underground pipeline data, and it also directly affects the subsequent underground pipelines. Reliability and socioeconomic value of information applications. The problem of spatial logic inspection of underground integrated pipelines has always be...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still many problems in the research on three-dimensional space collision detection of underground integrated pipelines. For example, the spatial analysis functions covered in most underground pipeline information systems are not comprehensive, the analysis functions do not start from the actual inspection level, the reusability of inspection functions is poor, and the results are accurate. The accuracy is not high, the inspection efficiency is limited, etc., and it is not suitable for the three-dimensional space prediction of underground pipelines.
