RFID anti-collision method based on continuous time slot grouping in storage environment

The invention relates to a RFID anti-collision method based on continuous time slot grouping in a storage environment, which belongs to the technical field of wireless radio frequency communication and identifies read tags, newly added tags and captured tags in the storage environment by adopting a tag preprocessing method, a time slot grouping method, a return sequence design method and a prefix retransmission method. According to the invention, it is found through verification that the method can keep good performance when the capture effect occurs, the number of the read labels changes, the read labels leave, the new labels are added and the total label number changes. The method is suitable for being applied to a large-scale label storage environment. 本发明涉及一种仓储环境下基于连续时隙分组的RFID防碰撞方法，属于无线射频通信技术领域，采用标签预处理、时隙分组、设计返回序列、前缀重传的方法对仓储环境下的已读标签、新加入标签和捕获标签进行识别。本发明通过验证发现该方法在发生捕获效应时、已读标签数量变化时、已读标签离开时、新标签加入时、总标签数量变化时，均能保持良好的性能，适合在大规模标签的仓储环境中应用。
