摘要
针对现有RFID系统中的不足,设计了一种基于ZigBee技术的有源RFID系统。阐述了有源RFID系统的硬件设计原理,分别给出了读写器和有源标签软件设计架构,并通过研究Z-Stack协议完成阅读器与有源标签之间的通信。采用TI公司的CC2591功率放大芯片,增大了读卡器与标签的通信距离。并通过增加休眠时间和减少通信流量完成了标签的低功耗设计。最终实现了远距离、多节点的有源RFID系统的设计。
For the lack of existing RFID systems, to design an Active RFID systems based on ZigBee technology. This paper elaborates hardware design of active RFID systems, respectively gives software architecture of reader and active tag, and completes the communication between reader and active tag by studying the Z-Stack protocol. TI＇s CC2591 power amplifier chip is adopted, increasing the communication range of reader and tag. And low-power design is achieved by increasing in sleep time and reducing communication flows. Ultimately the long-range, multi-node active RFID system is realized in this paper.
