摘　　要：针对传统射频识别系统存在识别距离短、安全性不高、组网不便、定位困难和功能单一等问题,提出了基于ZigBee技术的远距离射频识别设计。采用超低功耗控制器,通过CAN总线实时监测和显示,并利用神经网络的自适应性优化定位算法,有效解决了传统射频识别的弊端,拓宽了射频识别系统的应用范围。测试结果表明,该系统运行稳定可靠、数据收发准确、识别距离增大、定位准确性高,整体性能得到明显提高。In view of the traditional radio frequency identification system features problems of short identified distance,low security,difficulty of structuring network,and positioning,as well as unitary function,the remote RFID design based on ZigBee technology is put forward.By adopting low power consumption controller,through CAN bus real-time monitoring and display,and using neural network adaptive optimal positioning algorithm,the disadvantages of traditional RFID are overcome,and the applicable scope of RFID is expanded.The test result shows that the system runs stably,sending and receiving data precisely,identifying distance and positioning precision increases,and entire performance obviously enhances.
