摘 要
该设计是基于RFIC的智能门锁系统,主要完成对小区和其他重要部门的出入口安全控制,及对用户单元的监控。 工作过程为:用户刷卡开门时,读卡器读取卡中信息,主单片机将信息与内部数据库信息进行比较,进而判断该卡持有者的权限,控制开门。同时上位机显示和存储该卡信息及操作信息。用户也可以通过键盘输入密码开门。作为拓展部分,辅单片机采集用户单元的窗状态,温度、湿度等外部数据量,由上位机进行显示、存储,从而监控各用户单元。总之,RFIC读卡器负责读取RFIC卡的信息;辅单片机完成对各用户单元的信息数据采集;主单片机作为控制器,控制门的状态;上位机作为该系统的管理平台。 终,通过RFIC读卡器、主辅单片机和上位机的有机结合,形成了一个功能完善、可移植性高、操作性强的基于RFIC的智能门锁系统,通过对硬件的设计和软件对上位机的编程初步完成了所要求的结果。

Abstract
The design is based on the intelligent RFIC entrance guard system, main area and other important sector of the gateway to users, and safety control unit. Working process card for users: open the door, the card reader reads the information, information and internal chip, then compare information database access card holders of judgment, control to open the door. While PC display and storage card information and operational information. The user can also through the keyboard input password to open the door. As the auxiliary microcontroller, collection development, the window user elements such as temperature and humidity external data quantity, the PC on display, storage, and monitor the user unit. Anyhow, RFIC RFIC card reader is responsible for reading information, For each user complete auxiliary MCU units of information, data acquisition, The single chip microcomputer as controller, the control gate; As the system of the upper management platform. Finally, through RFIC reader, auxiliary SCM and PC organically, formed a complete functions, high portability and feasible RFIC based on the intelligent entrance guard system, through the design of hardware and software for PC programming preliminary results of the completed required.
