摘　　要：基于ISO18000-6C协议标准的UHF RFID系统中的读写器和标签之间的通信,采用CRC5和CRC16循环冗余校验。目前UHF RFID系统中,收发数据的循环冗余校验都采用按位校验法,本文根据已有的循环冗余查表校验法,提出一种适用于ISO18000-6C协议标准的新型循环冗余校验算法,极大地提高了循环冗余校验效率,非常适合用于嵌入式实时系统通信。实验结果表明,该算法将CRC5校验的效率提高了17%,将CRC16校验的效率提高了27%以上。ISO18000-6C protocol standards use CRC5 and CRC16 cyclic redundancy code between readers and tags. In order to improve the efficiency of the cyclic redundancy check in UHF RFID system, this paper proposed a new cyclic redundancy check algorithm for ISO18000-6C protocol standards, which greatly improves the efficiency of the cyclic redundancy check, and is very useful in real-time embedded systems. Experimental results show that this algorithm will improve efficiency of CRC5 by 17%, and improve efficiency of CRC16 by more than 27%.
