Abstract针对RFID读写器识别多标签过程中出现的冲突问题,研究并实现了EPC Class-1 Gen-2标准中的防冲突算法,即时隙随机算法(SR算法),同时针对SR算法的不足提出改进算法。改进算法采用不避让冲突时隙的处理方式,降低了由时隙的随机选取所导致的标签间冲突的概率。实验结果证明,改进后的算法在通信次数和吞吐率方面均优于原算法,有效提高标签识别效率。
Other AbstractThis paper analyzes and implements the anti-collision algorithm of EPC Class-1 Gen-2 protocol for the problem of signal collision.It presents an improved algorithm of it.The improved algorithm does not parry the collided slots,which can reduce the probability of collision caused by random slot choice.The results of the experiment show that the improved algorithm,compared with the original algorithm,has less communications and better throughout.So the improved algorithm is a feasible and efficient solution to identify EPC Class-1 Gen-2 tags.
