High-voltage electric airport tractor with intelligent traction speed regulation

The invention discloses a high-voltage electric airport tractor with intelligent traction speed regulation. The tractor comprises a whole vehicle controller, a walking electric controller and a driving motor, and further comprises a semi-automatic unhooking mechanism, a traction pin, a rear traction seat structural part, an upper traction force sensing seat, a middle traction force sensing seat and a lower traction force sensing seat, the upper, middle and lower traction force sensing seats are used for respectively collecting traction forces at the upper, middle and lower positions of the traction pin, the whole vehicle controller is used for calculating the whole vehicle traction force according to the traction forces at the three positions, and the whole vehicle controller is further used for acquiring the driving working conditions of the airport tractor and the traction force limit values corresponding to the driving working conditions, judging whether the actually-measured whole vehicle traction force e
