Hanging method, device and hanging system of grounding wire

The invention discloses a hitching method, device and system for a ground wire. The method comprises the steps that when it is determined that a telescopic rod module is located on the ground below a wire, a telescopic rod in the telescopic rod module is controlled to execute lifting operation; when it is detected that the distance between the telescopic rod and the wire reaches a preset distance, the hitching module is controlled to execute electricity testing operation on the wire; when the wire is in a power-off state, the telescopic rod is controlled to continue to execute lifting operation; when it is detected that the distance between the hooking head and the wire is smaller than a preset distance, the hooking module is controlled to execute hooking operation; in the process of controlling the hitching module to execute hitching operation, acquiring a pressure value between the hitching head and the wire by using a pressure measuring assembly of the hitching module; and when the pressure value is greate
