一种基于ZigBee无线射频识别系统的设计

摘要

Radio frequency technology is the integration of wireless sensor networks and radio frequency identification technology,and RFID technology,with traditional,mainly achieved transfer of information with the host compute through the serial port,resulting in waste of system resources in a multi-point acquisition. ZigBee network multihop transmission functions can achieve a wide range of information and can compensate for the lack of RFID technology. Especially in military applications,it is possible to achieve accurate delivery of weapons and ammunition and other military supplies,and to manage it depending on field applications fast,efficient,and to reduce management complexity,and to save labor costs. This article analyzed the RFID and ZigBee interoperability of key technologies, and selected CC2430 radio frequency chip to implement electronic identification. The system has low price,low power consumption,strong application adaptability and other characteristics.%无线射频技术是无线传感器网络与射频识别技术的融合，对于传统RFID技术主要通过串口来实现与上位机的信息传输，而在多点采集下造成系统资源的浪费；ZigBee网络多跳功能能够实现大范围的信息传输，且能够弥补RFID技术的不足，特别是在军事应用中，能够实现武器弹药等军用物资的准确配送，并根据不同战地应用领域进行快捷、高效管理，降低管理复杂度，节约人力成本；分析RFID与ZigBee互通关键技术，选用CC2430无线射频芯片实现电子识别；本系统具有价格低、功耗小、应用场合适应性强等特点。
