| Abstract: | 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. |
