【摘要】 本论文主要研究设计了一种新型多接口的感应式射频卡门禁/考勤系统。门禁系统是楼宇办公自动化的一个子系统,它能够完成对楼宇的出入口控制以及公司员工考勤的联动控制。随着计算机网络技术的迅猛发展,以及USB移动存储器的大量普及,使得基于以太网网络环境和带有大容量移动存储功能的门禁管理系统的设计开发成为未来门禁系统建设的主要方向。本文就针对这一要求,提出了一种切实可行的门禁系统设计方案。该方案突出的优点是结合了当前热门的TCP/IP协议和USB技术,利用成熟的以太网作为通讯手段,使用廉价的u盘作为大容量移动存储设备,具有一定的技术先进性和宽广的市场前景。论文一共分为六章,从门禁技术的发展出发,首先介绍了射频技术的相关原理,包括读卡器及射频卡的组成、种类及工作原理。在此基础上,论文详细阐述了门禁系统下位机的硬件和软件的设计开发。最后通过上位机网络通信程序的调试,表明了该系统能够有效上作,硬件和软件设计方法正确,既能满足门禁系统的基本工作要求,又兼有员工考勤记录的功能,同时也突出了其在同行领域内的先进性。更多还原

【Abstract】 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.更多还原
