Abstract

The invention relates to an unmanned aerial vehicle intelligent inspection identification method for a power transmission tower, wherein an intelligent inspection system is adopted to inspect an insulator, and the intelligent inspection system comprises an image acquisition module carried by an unmanned aerial vehicle, a preprocessing module, a feature extraction module, a feature fusion module, a prediction judgment module and a fault reporting module. The identification method specifically comprises the following steps: 1) shooting an image of the insulator and transmitting the image to the preprocessing module; 2) performing non-local average denoising processing on the image and inputting the image into a feature extraction module; 3) adopting a neural feature extraction network to extract insulator shape features and fault features;4) carrying out feature fusion on the extracted high-dimensional features, and 5) judging the features through a prediction regression network. According to the power transmission tower insulator fault identification method, real-time identification of the power transmission tower insulator fault is rapidly and accurately achieved, and the maintenance efficiency of the insulator is improved.

Description

technical field [0001] The invention relates to the technical field of fault inspection and maintenance of electric transmission towers, in particular to an intelligent inspection and identification method of an unmanned aerial vehicle for electric transmission towers. Background technique [0002] Today has entered the era of artificial intelligence and big data, and deep learning and neural networks have developed rapidly. The power grid occupies a very important position in our country, and the maintenance of the power grid is also important. The construction of a smart grid has been continuously valued. The overhead transmission line is a steel frame structure facility that erects the conductor to keep it away from the ground. Insulators play the role of connecting wires and fittings in overhead transmission lines. Whether there is a hidden trouble in the insulator will have a great impact on the stable operation of the power grid. Seriously, it will cause the insulator...
