Deicing method based on electric transmission line cable deicing robot

The invention discloses a deicing method based on an electric transmission line cable deicing robot. The electric transmission line cable deicing robot moves to conduct deicing on electric transmission line cables in the deicing process. The deicing method includes the following steps of calculating every spans of horizontal tension of the cables in an electric transmission line to obtain values of the horizontal tension of every spans when the electric transmission line is coated by ice, comparing the obtained values of the horizontal tension of every spans to obtain the maximum value in the values of the horizontal tension of every spans, starting a deicing motor of the deicing robot when the deicing robot moves to the cable with the maximum value in the values of the horizontal tension of every spans to remove half of the ice of the cable with the maximum value in the values of the horizontal tension of every spans, obtaining the maximum value in the rest of the values of the horizontal tension of every sp
