This application claims the benefit of priority to Chinese patent application No. 201810102295.1, filed on Feb. 1, 2018, which is hereby incorporated by reference in its entirety.
The present invention relates to a parking equipment, and more particularly to an automatic parking system and a parking and unparking method thereof.
At present, an automatic parking system with loading boards generally suffers from slow parking and unparking speed. The main reason is that the automatic parking system with loading boards generally needs to get and store the loading board twice, whether when parking or when unparking. When parking, a lifting device of the automatic parking system needs to move a pickup machine to a corresponding height for getting one loading board without load, if an in-out space of the automatic parking system have not one loading board without load therein. Then the pickup machine with the loading board without load is moved to the height corresponding to the in-out space by the lifting device and then moves the loading board without load to access the in-out space. When a vehicle is parked on the loading board in the in-out space, the pickup machine gets the loading board with the vehicle thereon from the in-out space and then is moved to a corresponding height by the lifting device for parking the vehicle. When unparking, if the in-out space has a loading board without load therein, the lifting device needs to move the pickup machine to the height corresponding to the in-out space for getting the loading board without load from the in-out space. Then the lifting device moves the pickup machine to a corresponding height for storing the loading board without load to an empty parking space. Then the lifting device moves the pickup machine to the height corresponding to the vehicle ready to be unparked for getting the loading board with the vehicle thereon from a corresponding parking space. Then the lifting device moves the pickup machine to the height corresponding to the in-out space for moving the loading board with the vehicle thereon to access the in-out space. Therefore, no matter when parking or when unparking, the lifting device generally needs to move up and down twice, the pickup machine needs to get and store the loading board twice, which makes the automatic parking system have a slower parking and unparking speed and then causes waste of time.
