基于RFID的教室门禁系统的设计与实现

Design and Implementation for Classroom Entrance Guard System Based on RFID

主要介绍了教室门禁系统各个模块的设计与实现。读写器硬件部分采用51单片机系列的STC11F32XE作为主控芯片,射频模块采用性价比较高的MFRC522芯片。软件部分重点阐述了射频识别通信底层驱动的实现,并在此基础上将卡片的操作以函数形式封装,以供用户调用。该系统设计开发的完成,为教室资源管理提供了便捷,并为校园一卡通的实现奠定了基础。

This paper mainly introduced a design and implementation for every module of the classroom entrance guard system.The RFID reader uses STC11F32XE of the 51 CPU series as main control chip and the ratio of high MFRC522 chip as the main chip of radio frequency module.Software part focuses on the realize of the bottom of the RFID communication driver,and based on this,encapsulate the operation of the card into functions which can be transferred by the customers conveniently.The achieve of the system design and development provides convenient for classroom resource management,and lay the foundation for the realization of campus card.
