The problem of fast identification of industrial multi-label has always been an urgent problem in the practical field of RFID technology.On the basis of analyzing the characteristics of existing anti-collision algorithms of RFID, this paper presents an improved algorithm for fast multi-label recognition.The algorithm counts the total number of digits "1" in the label ID before formally recognizing the label, and treats the statistical value as a group number to identify the identification tag, which effectively reduces the possibility of tag data collision.In addition, the new query prefix in the algorithm is generated according to the first collision bit, which effectively avoids the existence of empty search and reduces the system recognition efficiency affected by the label ID length to some extent.Finally, the algorithm only returns the data from the tag ID matching with the search prefix to the reader, which effectively reduces the system traffic.The simulation results show that the algorithm is stable in performance and has a throughput of 65. The algorithm can be used in industrial field effectively and realize fast reading of multiple tags.
