Research on adaptive grouping tag anti-collision algorithm based on RFID technology

RFID技术具有安全可靠、可远距离识别等特点,被广泛应用于智能识别与机器人技术中。传统的类标签算法普遍存在不足,文中基于RFID技术研究了自适应分组的标签防碰撞算法。自适应分组的标签防碰撞算法在一定程度上改善了多目标标签的情形,提高了系统的识别速度,且利用了阅读器与标签中的信息通道。仿真结果表明,自适应分组标签防碰撞算法可以大幅减少能量损耗,提高识别精度,弥补了传统算法的不足。

RFID technology is widely used in intelligent identification and robot technology because of its security,reliability and long-distance identification. As the traditional class tag algorithm is generally deficient,an adaptive grouping tag anti-collision algorithm is researched based on RFID technology. The adaptive grouping label anti-collision algorithm improves the situation of multi-target tags to some extent,increases the recognition speed of the system,and utilizes the information channel in the reader and the tag. The simulation results show that the adaptive grouping tag anti-collision algorithm can greatly reduce the energy loss and improve the recognition precision,which makes up for the deficiency of the traditional algorithm.
