超高频射频识别读写器的研究与设计

Research and Design of UHF RFID reader

超高频射频识别系统具有存储容量大、读写速度快、识别距离远和可同时读写多个电子标签等特点,已经在众多领域得到了广泛的应用。为了满足市场需求,对超高频读写器的内部结构进行了研究并提出了一种基于ARM的超高频射频识别系统读写器的设计方案。从硬件和软件两个方面对读写器的设计进行了阐述,给出了读写器的设计结构、工作流程以及相关的软件流程图。实际应用结果表明,该读写器具有读写速度快、读写效率高、识别距离远等优点,可以满足市场需求。

The system of UHF RFID has the advantages such as storage capacity, read and write speed, recognition distance, and can read or write multiple RFID tags simultaneously, which has been applied widely in many fields. In order to meet market requirements, this paper proposes a design project of a UHF RFID system interrogator based on ARM. In this paper, two aspects of hardware and software design of the interrogator are described, the design gives the structure of interrogator, work processes and the related flow chart of software. The practical results show that the interrogator has the advantages of read and write speed, efficient read-write, recognition distance and so on, which can meet market requirements.
