摘　　要：为解决标签不均匀场景的标签丢失问题,提出了一种可以应用在标签不均匀分布场景的基于排队论的标签漏读预警RFID防碰撞方法。该方法估算抵达阅读器识别区域内的标签数,通过分析标签的抵达率和阅读器的平均服务率,判断系统是否稳定。当系统不稳定时,通过提示使用者停止运动,减少标签丢失现象的发生。仿真实验的结果显示,该方法在标签不均匀分布的场景中有效地减少了标签丢失,提高了系统性能。In order to solve the problem of tag loss in tags uneven distribution scenario,a RFID anti-collision method based on tags missed read alert based on queuing theory was proposed,which can be applied in tags uneven distribution scenario.The method estimates the number of tags entering the reader’s identification area,and judges whether the system is stable by analyzing the arrival rate of tags and the average service rate of the reader.When the system is unstable,the user is prompted to stop the movement to reduce tag loss.The results of simulation experiments show that the method can effectively reduce the loss of tags and improve the system performance in the scene of tags uneven distribution.
