In recent years, with the development and improvement of the power grid structure, the construction of power lines has made great progress. However, due to the particularity of the geographical location and environmental conditions of power lines, there are many poles and towers, a wide area, and long lines. They are exposed to the wild all year round. In addition to being attacked by severe natural weather, various illegal and illegal behaviors have caused transmission line equipment short circuits, pole collapses, tower collapses, power outages and other external force damage accidents and cases. The trend is also increasing year by year, which brings huge economic losses to power supply companies.
