| 摘 要： | 为了改善基于RFID技术的门禁系统在获取电子身份标签信息时的冲突问题，通过引用马尔可夫链为时隙防碰撞法建立数学模型，并以此为基础对时隙法的性能进行分析，从而得出时隙法中定时隙对电子标签数目识别的影响，这为在已定时隙数的情况下合理规划门禁系统范围内的电子标签数目、提高识别效率提供了参考。

| Abstract: | In order to improve the getting information collision problem in the entrance guard system of RFID technology. This paper build a mathematic model for the slot method by quoting Markov chain, using it as the basis analyze the slot method performance and get the relationship between the number of time slots and the electronic tag identification, so it can provide a reference that the electronic tag numbers can be reasonable planed and the efficiency of identification is improved in the case of fixed number of time slots. |
