[0002] With the development of science and technology, AGV is more and more widely used in many industries for its flexible handling advantage. AGV is the abbreviation of Automated Guided Vehicle. In the stereo garage, AGV carriers usually have two forms, one is the AGV clamp wheel carrier, the other is the AGV carrier plate carrier. The AGV clamp wheel carrier can only carry vehicles on the flat parking spaces. If you need to carry vehicles on the second floor, you need an AGV carrier plate carrier. When the AGV carrier plate carrier is working, you need to place an empty carrier plate at the vehicle entrance and exit first. After the vehicle enters the carrier plate, the AGV carrier plate carrier places the carrier plate with the vehicle to the parking position. After receiving the parking command, the AGV carrier plate carrier needs to place the empty carrier plate at the vehicle entrance and exit position again, so that the AGV carrier plate carrier reciprocates to transport the carrier plate, resulting in low vehicle storage and retrieval efficiency.
