Multi-label Detection Method in Warehousing Wireless Scanning System

摘要

In view of logistics distribution digital management, construct a wireless sweeping system based on the Zigbee technology. The system scanned electronic tags by reader-writer which simultaneously reads many electronic tags. In RFID system, many labels simultaneously frequently maybe transmit data to a reader-writer. In order to avoid the collision of reader-writer read data, propose a multi-label collision detection algorithm applied in the RFID system. This algorithm stochastically hives coverage area's electronic tag off. In the group, collision detection and label's arbitration were realized. Compared with existing stochastically traffic algorithm and binary tree algorithm, this algorithm not only effectively reduced collision number of times, but also simple the electric circuit. Raised system's recognition speed and the reliability by conflict processing wireless sweeping system, and it provided a new recognition processing method for logistics distribution digital management.
