基于手机OMAP5910内核的UHF RFID阅读器的设计与实现

Design and Implementation of UHF RFID Reader Based on OMAP5910 kernel of Mobile Phone

RFID射频识别技术是一项非接触式自动识别技术。根据现代手机的射频系统覆盖频率已经达到900-2400MHz UHF频段、主流逻辑控制部分核心为中央处理器ARM925和数字信号处理器DSP C55X双核结构的开放多媒体处理平台OMAP5910,具有较强的控制能力和数据处理能力的特点。以此为基础,通过修改手机操作系统,在手机上实现了UHF频段RFID无源电子标签的阅读功能。实验表明,阅读距离可以达到至少10 cm,完全满足个人快速方便获取商品信息的需要,对于手机用户辨别真假商品具有实用价值。克服了传统RFID终端体积大不方便携带的缺点,扩展了手机功能,有利于促进电子标签这种新型技术取代条码的推广。

RFID radio frequency identification is a non-contact automatic identification technology.According to the features that of modern mobile phone RF system operation frequency range has reached 900 ～ 2400MHz UHF band,and the logic control core OMAP5910 has a strong ability to control and data processing capability for consisting of dual kernel ARM925 and DSP C55X.On this basis,by modifying the mobile phone operating system, realized a RFID reader to read the passive UHF tag.The experimental results shows that the reading distance can be at least 10cm,fully meet the individual to get products information quickly and easily,and it＇s valuable to for the mobile phone users identify fraud goods.This RFID devices can overcome the traditional RFID terminal＇s bulky inconvenient to carry and expand the mobile phone functions.It＇s helpful for promoting the electronic label to replace bar codes or laser label.
