摘要
随着RFID技术在我国的不断发展,它已经成为新兴产业的热门话题;为实现短距离、高精度的传输,经过研究,一种低成本高精度、高适用型载频为3.6864M的RFID无线识别系统的制作方法刚好满足要求,通过基于阻抗调制实现无源RFID读写器的方法,详细描述RFID读写器基本组成和基于单片机的RFID读写器设计;在这基础上分析了RFID读写器信令协议流程的处理原理及实现,并在实际的读取标签、一卡通等应用中取得较为理想的效果。
As long as RFID technology develops more and more in our country, RFID has been a hot topic in fresh industry. In order to realize transmission under short distance and high quarlity, we proposed a Low cost. high--precision, widely used wireless RFID reader whose carrier frequency is 3. 6864MHz. It is based on Impedance Modulation, and make the function of the RFID reader come true, and recount the constitution and the design of RF1D reader. Based on it, this paper analyzes the process of RFID protocol and collision--Anti arithmetic, getting a good result of the applications of reading tags , IC--TL and so on.
