Intelligent garage will information society is one of the most important infrastructure, parking management control system is an integral part of modern architecture. Along with the computer control technology development, the parking management control system function and hardware and software facilities also with his continuous development and improvement. This paper mainly expounds the design thoughts and automatic garage programming, the application of PLC controller as the field equipment signal acquisition and control. When their cars or master into the garage, when the car into the ultrasonic regional identity recognition relay work, garage door open, when the car to enter fully into the garage, delay 10 seconds after automatic garage door shut down; When the car to the materials, is located in the pressure inside the garage closing switches, garage door open, delay 30 seconds, automatic garage door lock, and realize the garage security, fire prevention, the pressure, and many other intelligent control. According to the management and control function demand, the full study related system components and working principle of the performance index, based on this system function design and hardware selection. The system of the garage management are of great help to transport the traffic flow, and the improvement of road transportation capacity have significant effects, have great practical value. Key words： PLC (programmable logic controller), Garage control system, Garage automatic door, Ladder diagram  目 录 摘 要 I ABSTRACT II 1 绪论 1
