基于RFID的图书管理系统.doc

PAGE １６ 摘 要 基于STC89C52单片机的图书馆管理系统主要是采用RFID射频、单片机和12864液晶、上位机、独立按键作为本设计核心器件，实现从下位机刷卡上位机显示图书借阅等信息。在设计中采用STC89C52作为主控器，实现把采集到射频卡信息进行转化成数据，并且在12864液晶显示出每张卡卡号，最后把卡号记录通过串口传输数据到上位机，上位机将记录传输到数据库ACCESS保存。图书馆借书管理系统中，登入不同的用户进入的界面操作是不同的，管理员和用户都可以通过上位机查询每本书的借阅记录信息，但是只有管理员账户进入可以在对进行图书的信息管理，例如进行增加、删除、修改、查询以及金额充值等操作。在下位机刷卡时液晶将显示每张IC卡的卡号，而管理员可以对每张IC卡进行注册和撤销和余额的充值管理，有效的IC卡才能与上位机进行相互通信，否则默认为无效卡。该系统将提供完备的功能，整体的设计控制低成本，易操作，我国的人口多，推广的市场一定会有前景。 关键词：STC89C52单片机、上位机、IC卡读卡器、液晶、串口； Abstract Library management system based on STC89C52 MCU mainly USES RFID radio frequency, MCU and 12864 LCD, upper computer, independent button as the core of the design device, to achieve from the lower computer card upper computer display library information. In the design, STC89C52 is used as the main controller to convert the collected rf card information into data, and each card number is displayed on 12864 LCD. Finally, the card number record is transmitted to the upper computer through the serial port, and the upper computer transmits the record to the database ACCESS for storage. Library management system, different users to enter login interface is different, administrators and users can query through the upper machine each book borrowing record information, but only the administrator account can enter in to manage the books information, such as add, delete, modify, query, and the amount prepaid phone operation. When the next machine swips the card, the LCD will display the card number of each IC card, and the administrator can register and cancel each IC card and recharge the balance management, effective IC card and the upper computer for mutual communication, otherwise the default is invalid card. The system will provide complete functions, the overall design control low cost, easy to operate, Chinas population is large, the market promotion will have a future.
