Key fittings monitoring method of transmission line based on cloud-edge cooperation

The stable operation of transmission line is one of the important links to ensure the security of power system. In the power grid, it is very important to identify and eliminate the hidden dangers of the key fittings of the transmission line for the stable operation of the power system. This paper presents a cloud-edge collaborative monitoring method. According to the fittings image uploaded by unmanned aerial vehicle(UAV) patrol survey, this method uses multi box detector(MBD) to preprocess the multi-scale feature map in the edge survey, and combines the feature Pyramid fusion technology to detect and identify the processed image in the cloud, so as to identify the hidden danger of fittings in the complex background. The method proposed in the experimental results table has the advantages of high accuracy and fast processing speed in the monitoring of key fittings of transmission lines.
