Professional detection method for urban underground drainage pipeline

Abstract

The invention discloses a professional detection method for an urban underground drainage pipeline. The professional detection method comprises the following steps that pipeline information of a drainage pipeline to be detected is acquired, wherein the pipeline information at least comprises pipeline distribution information and pipeline pipe diameter information; on the basis of the pipeline distribution information, a video detection module of a pipeline detection robot is used for acquiring a preliminary detection image of the drainage pipeline to be detected; the preliminary detection image is processed, and suspected fault part information of the drainage pipeline to be detected is extracted; the video detection module, a sonar detection module and a distance detection module of the pipeline detection robot are used for further detecting a suspected fault part so as to obtain a detection result of the suspected fault part. According to the professional detection method for the urban underground drainage pipeline, a to-be-detected pipeline can be simultaneously subjected to video detection and sonar detection, the detection is convenient and fast, time and labor are saved, theworking efficiency is high, and the same fault point can be positioned through the video detection module and the sonar detection module at the same time.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a professional detection method for urban underground drainage pipelines. Background technique [0002] Urban drainage pipes are an important way to remove urban sewage and rainwater. The criss-crossing underground drainage pipes in the city are an extremely important municipal facility, and even become the infrastructure for the stable development of the city. Its normal operation is to ensure the normal order of urban production and life. Important guarantee. Due to the harsh internal environment of urban underground pipelines, pipeline failures such as damage, leakage or blockage are prone to occur, which affects the normal drainage function of urban underground pipelines, thereby affecting the production and life of urban people. In view of this, it is very important to regularly inspect the urban underground drainage pipes and detect various technical parameters ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to at least solve the technical problems existing in the prior art, and especially innovatively proposes a professional detection method for urban underground drainage pipes, which effectively solves the problem that both video detection and sonar detection equipment in the prior art are used alone , Two sets of equipment need to be used for construction in sequence during detection, which is extremely inconvenient, time-consuming and laborious, and has low work efficiency, and the detection results of the two detection equipment cannot locate the same fault point at the same time
