Problems solved by technology

This is very inconvenient, the cost of the second set of equipment is high, and the construction of the second set of equipment in batches is time-consuming and laborious, the construction is cumbersome, and the labor intensity of the workers is high
In addition, the detection data of the two kinds of detection equipment cannot be displayed on the same main controller at the same time, so that the two kinds of detection results cannot locate a fault point at the same time

Abstract

The invention relates to a sonar video amphibious detection system for pipelines. The sonar video amphibious detection system comprises an amphibious image module, a central control module and a display module. The amphibious image module obtains pipeline sound wave information and pipeline image information of a pipeline to be detected; the central control module comprises a decoding unit, a cutting unit, an identification unit and a superposition unit; the decoding unit is used for performing decoding processing on the pipeline wound wave information and the pipeline image information, respectively; the identification unit identifies a boundary of the pipeline to be detected and a liquid level position within the pipeline; the cutting unit is used for performing twice cutting on the pipeline sound wave information; the superposition unit is used for superposing the pipeline sound wave information and the pipeline image information after twice cutting. The sonar video amphibious detection system for pipelines are capable of simultaneously detecting overwater image videos and underwater sonar videos of the pipelines without discharging water from the pipelines; as a result, equipment cost and construction labor intensity are reduced; synchronization of the overwater image videos and underwater sonar videos is realized; the detection efficiency of the pipelines and the accuracy of detection results are improved.

Description
