摘要
给出了一种改进型的RFID读写器设计方案。介绍了各硬件模块,并给出了软件的总体流程、防碰撞算法及实现代码,最后进行了研发测试。对比基于射频芯片的RFID读写器设计,此方案提高了系统灵敏度和读写距离。本设计拥有自主知识产权,已用于开放式门禁系统。实践表明,该系统电路稳定,运行正常。
An improved method in the design of the RFID reader is discussed. All of the hardware modules are introduced, and the software overall flow,anti-collision algorithm as well as the realization codes are given. Finally,some tests show that this method can enhance the working distance and the system sensitivity compared with the method based on a RF chip .The design has own-intellectual-property right. Practical applications indicate its good performance and stability.
