摘　　要：为了准确定量的评判现代物流环境下射频识别(RFID)系统防碰撞性能的优劣以及各种防碰撞算法对系统碰撞的改进程度,通过构建各种碰撞过程的概率模型,给出用于检测防碰撞算法性能的定量的评价参数。利用给定参数下进行仿真试验,验证了典型RFID系统碰撞过程概率模型中所涉及的关键评价参数的可靠性。对RFID系统碰撞过程的概率建模和随机分析,为现代物流环境下RFID系统的防碰撞物理性能检测提供了一种新的评价手段。For evaluating the performance of RFID anti collision protocol accurately and improving the anti-collision capability of different anti-collision algorithms of modern logistic RFID system, various probabilistic models of collision mechanisms were established. Furthermore, a set of evaluation parameters was given to detect the performance of anti-collision algorithms. In order to verify the reliability of the evaluation parameters involved in two probabilistic models in RFID collision, the computer simulation experiments were conducted to explore the reliability of key parameters in the probabilistic models. According to the probabilistic modeling and stochastic analysis of RFID collision, a new evaluation tool for anti-collision detection of modern logistic RFID system was suggested.
