摘　　要：针对传统射频识别技术存在传输距离短、灵活性差和设备成本高等问题，设计了一种基于ZigBee技术的电子标签识别系统。系统以TI公司的CC2530和Nordic公司的nRF24LE1分别作为无线通信节点的收发芯片和读写器的射频芯片，通过星型网络实现电子标签信息的采集和传输，给出了ZigBee终端节点和协调器节点的软硬件设计。在室内外环境下对该系统进行现场测试表明：电子标签信号发射距离为25～65 m，ZigBee无线模缺在200 m范围内实现有效传输。Aiming at the problems of traditional radio frequency identification technology with short transmission distance, poor flexibilityand high equipment cost,an electronic tag identification system is designed based on ZigBee technology. In the system,TIs CC2530 chipand Nordic＇s nRF24LE1 chip respectively serve as transceiver chip of wireless communication node and microcontroller of radio frequen-cy. Electronic tag information is collected and transmitted by the star network. In the paper,the software and hardware design of ZigBeeterminal node and coordinator node are given. The test result in indoor and outdoor environment shows that signal launch distance of e-lectronic tag is 25 to 65 meters and ZigBee wireless module within 200 meters can realize communication effectively.
