[0002] The main advantages of semi-trailer trains are: the semi-trailer and the tractor use a traction seat and traction pin, which shortens the overall length of the train, improves driving stability and safety, and increases the maneuverability of the entire train; part of the semi-trailer load is borne by the tractor, thereby improving the adhesion quality of the tractor's driving wheels and increasing the traction of the tractor. During the connection, the semi-trailer train needs to be connected through a connecting device, that is, the traction seat and the traction pin are docked to achieve connection and ensure normal transmission and transportation in the later stage.

[0003] The existing connection device cannot achieve auxiliary positioning installation during connection, and the position can only be adjusted manually and by a single camera unit. This docking method has extremely strict requirements on the driver's driving skills and experience. Once the operation deviates, it will not only waste operation time, but may also cause serious structural damage. Therefore, there are great limitations in actual use and there is room for improvement. Summary of the invention
