摘要: 提出一种基于电子标签Tag的ID返回及模式串识别过程的RFID标签识别算法,解决了RFID仲裁过程中存在的零标签响应问题。实验结果表明,对5 000个标签样本进行处理时,该算法所需平均标签响应次数为经典算法Memoryless的48.74%,为Tree Split的33.89%。对标签ID的广播次数平均不超过上述2种算法的76.35%,缩短了标签识别时间,提高了标签识别效率。

Abstract: This paper presents a RFID tag identification algorithm based on Tag’s ID feedback and model-string recognition, and solves the zero-response problem in the RFID arbitration. With 5 000 tags swatch, experimental results show that this algorithm takes 48.74% and 33.89% times of Tag response, compared with the Memoryless and Tree Split. The ID broadcasting times is less than 76.35% of that two classic algorithms. It is more efficient and shortens the time needed during the arbitration process.
