New Multi-interface Access Control Time And Attendance System

This thesis chiefly researches a new type of RF card Aeeess Control System which has more interface. Aeeess Control System which belongs to Building Automation System, now can not only controls entranceways of buildings but also combines with the functions of company work-checking .With the rapid development of computer network technology and the popularization of USB-mass-storage , the design and development of Aaccess Control System based on Ethernet and possessing the functions of mass-mobile-storage has become an important aspect of the future Access Control System's construction. In allusion to this new request, the thesis bring forward an available scheme, The outstanding excellency of this scheme is integrating the TCP/IP protocol and USB bus to Aeeess Control System, using Ethernet as communication method and taking lowcost U—Disk as mass-storage equipment. So at a certain extent, it will have some technology advantage and a bright market foreground.The whole thesis includes six chapters. On the basis of the development of induct-mode Aeeess Control System, at first this paper generally Introdues some technology of RFID, including its feature ,type,composing and IC card. Then it introduces the technology of Entrance Guard System. Based on these, the paper discusses the design of the Aeeess Control System detail, give out the whole design scheme including the hardware and software. Finally with the test of communication between system and computer, the result denotes that the system can work steadily and the design is correct. As the full functions of Aeeess Control and work-checking System , it also shows the advantage in the same domain.
