into account technological advances and the needs of different users, priority should be to choose a good opening, according to the standards has been the design, production equipment, to avoid patibility problems caused by the system difficult to upgrade or expand. As the outdoor facilities of the garage levels of the actual user, the system39。s ease of operation is particularly important, improve the system if it is not the correct use can also play a role in its prevention. It is only through rational, scientific, strict design and construction work, the right application can be managed more convenient and safe. Automated parking is the unity of the largescale plex mechanical and electrical products, machinery parts equivalent to the human body, the electrical equivalent of some of the people39。s nerves. Electric machine with a high degree of unity, so that the automated parking garage has bee the modern science and technology and Integrated Products. PLC technology used in place of the relay control technology can greatly enhance the convenience of the garage, so that the garage to achieve a high degree of automation, intelligent management, put an end to the possible drawbacks, so that the management has bee very easy, and has Openness, patibility. Garage access control system into a variety of devices in one, each of which play a role, with the aim of comanagement of the car park entrance, so that the car is more safe and effective management. PLC is based on microprocessor, a bination of puter technology, automation and munication technologies developed from a new type of industrial control devices. It has a simple structure, easy programming, high reliability, it has been widely used in industrial processes and automation in the position. According to statistics, industrial automation PLC is the most widely used devices in a device. Experts believe that the PLC will bee the main means of industrial control and one of the important infrastructure, PLC, robotics, CAD / CAM will be the three pillars of industrial production. Using PLC technology for the management of the garage in the next life will certainly be popular and to a greater extent.
