The Research And The Design Of The Embedded Control At Gate System

The control at gate system is the system that passes in and out to carry on a valid management by computer control technologies. It can carry out high-efficiency, high technology of modern management. Time passes in and out card holder legal power and allows to pass in and out can unify to carry on by the management conveniently, all the detail and report about personals pass in and out to the police as an information. The data reflect to the management center, and could be searched in all history informations.It not only can raise the efficiency, but also carried on a valid management, and carry out to guard against theft effectively. Based on the development requirement, the system plan to implement a access control system with functions of card-reading,printfinger identification, password identification ,displaying and data-outputting in the Wiegand format. With the help of the I/O systems of the singlechip,we integrate the card-reading module, the printfinger identification module,LCD,keypad and other circuits together, and control all these parts via the singlechip.In the course of the development of the whole access control system,In the development process of this control at gate controller system, I am responsible for the control at gate controller central mold piece, pick up the hardware design and the software development of the driver module of the printfinger identification subsystem(SM-60) in the AT89S52.The purpose is to work out software and hardware function.To sum up, the thesis has developed a set of the various collection function the control at gate system in an integral whole system, it may be used for the intellectualized project for housing estate or the building world. Owe systematic exploitation be the building world or housing estate scientific management, as well as the construction being suitable person occupies the environment to have the certainly positive sense.
