Pipe point suspension inspection method and system based on spatial relative position

Abstract

The invention relates to a pipe point suspension inspection method and system based on a spatial relative position. The method comprises the steps: S1, importing a to-be-detected pipeline surveying and mapping graph, and selecting an inspection range and a pipe point detection buffer range; s2, traversing starting points of all pipelines only connected with one pipeline in the inspection range, judging whether the pipeline are end equipment or not, if yes, not suspending the pipeline, and otherwise, executing S3; s3, judging whether only one pipeline exists in the pipeline point detection buffer range of the starting point of the pipeline or not, if so, not suspending the pipeline, and otherwise, executing the step S4; s4, judging whether the other pipelines detected in the S3 are connected with the end point of the original pipeline or not, if so, not performing suspending, and otherwise, performing suspending; s5, traversing the end point of the pipeline which is only connected withone pipeline within the inspection range and is not suspended at the starting point of the corresponding pipeline, and finding out the end point of the suspended pipeline in the same way from S2 to S4; and S6, marking a starting point and an ending point of the suspended pipeline and generating a position information list. Compared with the prior art, the method and system have the advantages of high efficiency, high precision and the like.

Description

technical field [0001] The invention relates to the field of urban underground pipelines, in particular to a method and system for inspecting pipe point suspension based on spatial relative positions. Background technique [0002] Urban underground pipelines refer to water supply, drainage, gas, heat, electricity, communications, radio and television, industrial pipelines and their ancillary facilities within the city. They are the material basis for exerting urban functions, ensuring urban economic and social health, and coordinated development. It is an important infrastructure and "lifeline" to ensure the operation of the city. In recent years, with the rapid expansion of urban construction and the continuous deepening of urban transformation, the mileage of underground pipelines has continued to increase. Relevant enterprises and data management departments have accumulated a large number of new pipeline data that need to be updated and urgently need to be stored. There...

Problems solved by technology

Therefore, to perform data quality inspection on urban underground pipeline data, one of the steps is to check the suspension point. The suspension point is that this point should be on a line but there is no such point on the line, that is, the suspension point, but due to the overview of the data image There is no magnification, the distance between the point and the line is very close, and it needs to be magnified many times to find the suspension. The end point of one line may intersect or have a gap with another line, which leads to the incomplete capture of the positioning during surveying and mapping. Manually checking the suspension point is inefficient and has a high error rate. , need an automatic and efficient automatic detection method
