Vibration damper defect detection method based on dynamic adaptive weight loss

Abstract

The invention discloses a stockbridge damper defect detection method based on dynamic adaptive weight loss. The method specifically comprises the following steps: making stockbridge dampers and a defect training data set and a test data set of the stockbridge dampers; constructing a dynamic adaptive weight network to obtain a dynamic adaptive loss function weight coefficient, and constructing a stockbridge damper defect target detection algorithm model based on the dynamic adaptive loss function weight on the basis of the weight coefficient; according to the training data set, training the stockbridge damper based on the dynamic adaptive loss function weight and the defect target detection algorithm model to obtain a trained stockbridge damper defect target detection algorithm model; enabling the test data set to sequentially pass through the trained stockbridge damper defect target detection algorithm model to obtain stockbridge damper defect detection results; according to the method, end-to-end stockbridge damper and defect detection of the stockbridge damper can be simultaneously achieved through one model, the detection efficiency is improved, only a small number of parameters are introduced in the training process, parameters are not introduced in the testing process, and the detection precision is greatly improved.

Description

technical field [0001] The invention relates to the field of power system equipment detection, in particular to a method for detecting the defect of an anti-vibration hammer based on dynamic adaptive weight loss. Background technique [0002] As the carrier of electric energy transmission, overhead transmission lines are exposed to the wild for a long time, and all their components are vulnerable to natural environment. The anti-vibration hammer is an important part of the overhead transmission line, which protects the overhead line by absorbing the energy of the overhead line due to wind vibration. Therefore, inspection of anti-vibration hammers is an important part of regular inspection of overhead transmission lines. However, because high-voltage and ultra-high voltage overhead transmission lines are mostly distributed in areas with complex terrain in the wild, and the size of anti-vibration hammers is small, manual The inspection efficiency is low, the cost is high, and...

However, increasing the network scale or adding an attention mechanism will increase the computational complexity of the algorithm model, and will also introduce a certain amount of parameters in the model training and testing process, so more computing resources are consumed
