摘要
功耗问题制约着射频识别(RFID)系统的应用领域,论文依据射频识别系统特点和工作原理,在读写器端将硬件结构级和软件级功耗优化相结合,在完成射频识别、存储器管理、时钟控制和通信接口的基础上,对待机和射频读写时采用不同的功耗策略,设计实现了一种面向低功耗设计的射频识别系统,最后对功耗情况进行了实验比较和分析.测试结果表明该系统完全达到低功耗应用要求,并且已经在澳门海关得到了成功运用.
The application area of radio frequency identification （RFID） system has been limited by the problem of power consumption. The combination of power optimization on both hardware structure level and software level is presented to search for a better solution of low-power consumption. Different power consumption strategy was brought forward according to whether the system identify responder or not. A practical original system based on this method is also discussed. According to the sys- tem testing result ,the power consumption has completely met the requirement of application case. Moreover, the system has been working satisfactorily at Macao Custom.
