摘要
RFID是一种自动识别技术,由于低频频段具有很强的场穿透性,低频RFID系统可以在需要良好的场穿透性的环境下良好工作。针对现有低频RFID读卡器的不足,提出了一种多天线大功率低频RFID读卡器的设计方案,通过引入多天线轮询技术和大功率射频技术,有效地提升了低频RFID读卡器的识别范围,提高了低频RFID系统的工作性能和功能扩展。完成了读卡器的总体结构设计和软硬件的开发,并对读卡器进行了功能测试。
Radio Frequency Identification(RFID) is a kind of automatic identification technology. Low-frequency RFID signals can penetrate through most objects. Thus, LF RFID System works well in the environment which requires good field penetration. According to the shortcomings of existing LF RFID readers, a kind of multi-antenna high power LF RFID reader is presented. By using multi-antenna technique and high power radio frequency technique, the identification range of LF reader can be expanded and the performance and function of LF RFID system can be promoted. It introduces the overall structure of this reader and analyzes the concrete implement both in hardware and software. The final functional test tells that this reader works quite well.
