本文研究了RFID系统中阅读器冲突f*l题，分析了三种阅读器冲突问题，并给出了冲突模型。对目前已有的

阅读器防冲突算法进行了分析比较，并在Pulse算法的基础上提出了一种改进型的算法，降低了阅读器在控制通道里的冲突

概率并提高了阅读器阅读速率，对该算法的理论分析表明，该算法适合于移动式阅读器网络或手持式阅读器的应用。-This paper studies the RFID reader system, the conflict f* l title, analysis of three kinds of readers conflicts, and gives the conflict model. Readers of the currently available anti-collision algorithms are analyzed and compared, and the Pulse algorithm is presented based on an improved algorithm, reducing the reader in the control channel where the probability of conflict and increased reader reading rate, The theoretical analysis of the algorithm show that the algorithm is suitable for mobile network or handheld reader reader application.
