摘　　要：林产品物流应用RFID管理时,存在着标签数量变化范围大的问题,传统固定帧时隙的抗碰撞算法效率仅为0.116。为了解决该问题,本研究选择了空降兵DS5 UHF RFID手持机为硬件基础,应用Microsoft Visual Studio 2013作为开发工具,设计了林产品物流RFID手持机系统。采用抗碰撞算法进行仿真,获得了9条识别标签数据,通过帧长和识别标签数反推外界标签的总规模数,调整下一帧的帧长与之匹配,从而提高了RFID系统在林产品物流场景中的识别效率,提高至0.315。The range of amount of electronic tags was excessively changed when RFID was applied in forest products logistics management, and the efficiency of the traditional fixed frame time slot is only O. 116. To solve the problem, this study chose the airborne troops DS5 UHF RFID handset as the hardware foundation and used Microsoft Visual Studio 2013 as the development tool to design the RFID handset system of forest products logistics. In the paper, simulation tests were carried out by using collision -resistant algorithm, and obtained nine identification tags. the scale of the external electronic tags can be estimated through the frame length and the number of recognized tags. The identifiable efficiency of the RFID system achieved 0. 315 by adjusting the frame length of the next fi＇ame.
