With the development of computer control technology, the function, software and hardware of management and control system have also been improved continuously. The paper presents a plan of using Programmable Logic Controller (PLC) to manage the instructions of entering, leaving and parking, to realize the automation of the parking lots and reduce the operation cost. It is suitable for small and medium-sized parking lots. The parking lot consists of 18 parking spaces, the Entrance Detectors, the Barrier Management System, and seven segment LED whose function is to show the numbers of the vehicles in the garage and the remaining numbers of the parking spaces by the lights, and so on. And it establishes an automation control system basing on PLC to realize the automatic control of the parking lots. The system can realize the automatic control of the vehicles’ entering and leaving as well as the automatic display of the parking spaces in the garage. Owing to PLC’s reliability, operability, flexibility and other advantages, this control system has much excellence compared to the conventional parking lot, such as its short maintenance cycle, convenient adjustment, low cost, easy operation, high reliability, and the strong practical value, and it also can greatly improve the design efficiency.
