Abstract

The invention discloses an overhead transmission line channel inspection system based on an unmanned aerial vehicle, a second support and a first support are fixed to the top and the bottom of a connecting box respectively, and a first connecting column is welded to the bottom surface of the connecting box and fixedly connected with an image acquisition device; a second connecting column is welded to the top face of the connecting box and fixedly connected with a multi-rotor-wing unmanned aerial vehicle device. The hidden danger analysis method sequentially comprises the following steps of setting parameters of the unmanned aerial vehicle; dividing the power transmission line into a plurality of rectangular measuring areas, and determining control points and check points; exporting unmanned aerial vehicle position information corresponding to the unmanned aerial vehicle image, unifying a coordinate system, processing the image, and adjusting the aerial triangulation adjustment precision to one pixel; performing inversion to generate an LAS color point cloud, and obtaining an orthographic image map; and discriminating objects which may cause potential safety hazards to the power transmission line by using the convolutional neural network model. The invention has the advantages that remote sensing images are automatically collected, the collected images are calculated and analyzed through the convolutional neural network, and early warning of line safety is obtained in time.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle-based overhead power transmission line channel inspection system and a hidden danger analysis method. Background technique [0002] With the development of the power system, the scale of the power grid is expanding day by day, and the structure of the power grid is becoming more and more complex. As an important part of the power grid structure, the transmission line plays a vital role in the safe and stable operation of the power grid, and because the transmission line is outdoors, it faces complex and changeable environmental conditions, and natural factors and human factors may affect the normal operation of the transmission line. The operation will cause harm, thus affecting the safe and stable operation of the entire power grid. In terms of types, transmission lines can be divided into overhead lines and cable lines. Tree growth, house building, construction, etc. can threaten the safety of ove...
