Abstract-In order to design a vertical lifting three-dimensional garage control system, and to achieve the mechanical three-dimensional garage of the university automatic operation, the photoelectric sensors, hall pressure sensors and programmable logic controller (PLC) are used. The results show that the threedimensional garage control system can run safely and reliably, and each sensor can perform fault self-diagnosis and carry out certain treatment on the fault. In conclusion, the three-dimensional garage control system designed is feasible, and it can get wide extension and application.
