Power plant water supply pipeline leakage detection method and system

Abstract

The invention discloses a power plant water supply pipeline leakage detection method and system. The method comprises the following steps: collecting a video image and performing background preprocessing on the video image to acquire a pipeline leakage candidate area image; processing the candidate area image according to an automatic data enhancement technology and a cost sensitive learning method, and training to obtain an OfficientDet classification recognition model; determining m candidate area images and inputting the m candidate area images into an OfficientDet classification recognition model to obtain a detection result; and determining a plurality of corresponding video images in the video images according to a detection result, and performing secondary judgment on the detection result by adopting a Hausdorff Distance image similarity measurement method to obtain a final detection result. According to the method, the detection result is obtained by preprocessing the background data and constructing the OfficientDet classification recognition model, and secondary judgment is further performed on the detection result, so that the accuracy of pipeline leakage recognition is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a method and system for detecting leakage of a power plant water supply pipeline. Background technique [0002] The water supply pipeline is an indispensable part of the power plant. It is used for water intake, input, water quality treatment and water distribution. Because the environment of the power plant is generally harsh, the aging of the pipeline or the loosening of the pipeline joints caused by the mechanical vibration of large machines may cause the water supply pipeline to break down. Leakage problem. According to the degree of leakage, it can be divided into leakage, dripping, heavy leakage and flow, no matter which one will affect the normal operation of the power plant, and even cause safety accidents such as short circuit, fire, etc., causing huge losses to the power plant. Therefore, monitoring the working status of water supply pipelines is very import...
