Power transmission line monitoring method and device and electronic equipment

The invention provides a power transmission line monitoring method and device and electronic equipment, and relates to the technical field of power transmission lines, and the method comprises the steps: detecting a target vehicle with an actual distance to a power transmission line smaller than a first preset distance through radar equipment, and transmitting prompt sound waves to the direction of the target vehicle through a directional sound wave loudspeaker; when the actual distance between the target vehicle and the power transmission line is smaller than a second preset distance, collecting a current image through the camera, wherein the current image comprises the target vehicle and the power transmission line, and the second preset distance is smaller than the first preset distance; identifying a target license plate number of a target vehicle in the current image through an AI identification device, and querying a target vehicle owner terminal corresponding to the target license plate number; and sen
