基于ARM的2.4G RFID远距离读写器的设计

Design based on ARM's 2.4G RFID long range reader

随着RFID技术研究和开发的不断深入,2.4G RFID设备的研制逐渐成为研发的热点。相比无源RFID标签,2.4G有源电子标签具有传输距离远、数据速率高、多标签识别速度快及处理能力强等诸多优点,因此智能交通运输,资产管理,人员定位,自动考勤系统等应用场合有着天然的优势。文章基于ARM微处理芯片LPC2136,设计了一种2.4G RFID远距离读写器,该读写器经过长时间的测试和应用,在多个系统中运行稳定。

With the development of RFID technology research and development, the development of 2.4G RFID device has become the focus of research and development. Compared with passive RFID tags, 2.4G active electronic tag has the advantages of long transmission distance, high data rate, multi tag identification speed and strong capability of processing, so the intelligent transportation, personnel positioning, application of automatic attendance system has the advantage of natural. In this paper, ARM micro processing chip based on LPC2136, the design of a 2.4GRFID long-distance card reader, the reader through the test and application of long time, stable operation in multiple systems.
