摘要
介绍了基于ISO/IEC14443 TYPE B协议的13.56MHz的RFID阅读器的设计。给出了设计的硬件电路和防冲撞算法的软件实现,最后给出了示波器测试的实验结果。本文所用的阅读器芯片为瑞士μEM公司生产的模拟前端集成电路芯片EM4094,微控制器使用了ARM7芯片LPC2104,防冲撞算法使用传统的基于ALOHA的算法。
The design of a 13.56 MHz RFID reader conformed to ISO/IEC 14443 Type B protoeol is introdueed. The hardware eireuit, the anti-eollision algorithm and some experimental results are presented. The ehip used to design the reader is EM4094, whieh is a highly versatile produet of EM Mieroeleetronie Corporation. The mieroehip LPC2104 is used as the mieroeontroller. The anti-eollision algorithm used in this paper is the aloha-like algorithm.
