摘　　要：在OPNET平台上建立了通用的RFID网络模型,并对UHF频段的RFID主要标准ISO18000-6中的ALOHA类防碰撞算法进行仿真,得到了一组最优化设置曲线供工程应用参考,同时给出具体执行方法。仿真结果表明,优化后算法可使标签识别速率接近最优值。An all-purpose RFID network model has been set up using OPNET platform in this paper. ALOHA-type anticollision algorithms in the main standard ISO18000-6 of UHF frequency RFID are emulated through this model. A group of optimization curves for setting parameters have been got, which provide reference in projects. And idiographic methods for executing the optimized algorithm are proposed. Emulation shows that, speed of tag identification can be close to the optimum value using optimized algorithms.
