摘要
有源RFID是一种自动识别技术,在追踪和识别高价值商品方面具有突出优势。针对通信距离的增加,有源RFID系统出现识读不可靠、数据出错等问题。构建了基于CC2510的有源RFID系统,并结合硬件特性,重点对读写器与有源电子标签之间的通信数据帧标识、数据帧结构、标签防冲突处理和数据错误重传机制等方面进行探讨和设计。实验结果表明,改进后的通信机制对不同的测试环境具有一定的适应能力,表现出较好的可靠性。
Active RFID is an automatic identification technology,which has advantages in tracking and identifying high-value commodities.The problems of identification unreliability and data error are easily occurred in active RFID system with the increase of communication distance.The active RFID system based on CC2510 was designed,the communication data frame ID,data frame structure,anti-collision handling tag and retransmission mechanism for data errors between reader and active electronic tag are designed by hardware charcteristics.The test results show that the improved communication construction is reliable and the RFID system is available in different test environments.
