When the ground distance and the crossing distance of the transmission wires are changed due to the reasons, huge potential safety hazards are caused to the operation of the transmission lines, in order to avoid operation accidents caused by crossing out-of-limit, operators are required to monitor crossing parts in a reinforced mode, the crossing distance of the transmission wires is measured at any time, the change condition of the crossing distance is mastered in time, measures are taken rapidly to eliminate fault hidden danger, and safe operation of a power grid is guaranteed.
