Construction machinery hidden danger detection method of power transmission line

Abstract

The invention discloses a construction machinery hidden danger detection method for a power transmission line. The construction machinery hidden danger detection method comprises the following steps:acquiring images in a power transmission line channel and around the power transmission line channel in real time; making a data set of large construction machinery existing in a power transmission line channel, and randomly distributing according to a ratio of a training set to a test set of 4: 1; performing image preprocessing on the training set; processing the training set by adopting a multi-sample image synthesis method to obtain new training set sample data; training the new training set sample data by using a Faster R-CNN + FPN model to obtain a detection model of the hidden danger ofthe power transmission line channel; carrying out image target detection on the test set, updating detection model parameters, and carrying out secondary verification on the test set; and detecting the image acquired in real time by using the updated detection model, and detecting whether a large construction machinery hidden danger exists in the power transmission line channel or not. According to the construction machinery hidden danger detection method, the generalization problem of the detection model is solved, and the false alarm rate and the missing report rate are reduced.

Description

technical field [0001] The invention relates to a hidden danger detection method for construction machinery of transmission lines, belonging to the technical field of transmission lines. Background technique [0002] With the continuous advancement of the urbanization process and the rapid development of the social economy, the scale of the power grid continues to expand, and the workload of transmission line safety maintenance also increases. The power sector spends huge manpower and material resources on line safety maintenance work every year. . [0003] In particular, large-scale construction machinery poses the greatest threat to the safety of transmission lines. Failure to take preventive measures in time will lead to the risk of tripping the transmission line. Casualties and other major accidents; cranes during construction are easy to hang up the transmission line due to operator errors or limited vision; excavators, bulldozers and other construction machinery cause...

Problems solved by technology

However, these methods have the following disadvantages: 1. It is necessary to obtain real-time continuous frame images for analysis, but the camera devices installed on the high-voltage transmission line are basically powered by batteries, and it is not feasible to transmit electric energy by wires. The capacity of the battery determines In order to obtain real-time image frame information, it is difficult to obtain a single image every half an hour or even longer; 2. The method based on video analysis can only detect objects that change in continuous frame images, and cannot detect specific types. 3. The detection results based on video analysis methods are easily affected by noise and other factors, resulting in a large number of false positives
