摘　　要：针对有源电子标签功耗和防碰撞问题,给出了一种基于IEEE802.15.4标准和MG245X片上系统的2.4 GHz低功耗有源电子标签实现方法.从硬件电路和软件程序两个方面联合优化,设计了有源电子标签和标签读写器,分析了标签休眠时间与功耗及标签最大移动速度的关系.测试结果表明,该标签休眠模式下工作电流小于1.7μA,空旷环境下有效通信距离大于60 m,满足低功耗和远距离读写实用要求.To the problems of power consumption and data collision avoidance for active RFID tag, based on IEEE 802. 15.4 standard and MG245X on-chip system, a low power 2.4 GHz active RFID tag realization approach is proposed. With combined optimization of the hardware circuit and software program, the active RFID tag and corresponding tag reader is designed. Then the relationship among tag sleep time, power consumption and maximum moving speed is analyzed. Test results show that, the working current of RFID tag is less than 1.7 μA in sleep mode, the effective communication distance in open environment is more than 60 m, therefore the practical requirements of low power consumption and long reading and writing distance can be satisfied.
