资料介绍

分析连续碰撞位探测防碰撞算法,修改探测模式字的计算方法,改进碰撞位探测机制,使用Verilog HDL设计碰撞位探测防碰撞算法电路模型。电路包括读写器和标签中的碰撞位探测控制电路,在读写器端引入并行流水机制。仿真实验表明,电路能准确、快速地探测实际存在的多个连续或非连续的碰撞位串,且该电路能并行流水工作,减少碰撞时隙,提高防碰撞算法的效率,对射频识别(radio frequency identification,RFID)在快速移动领域中的应用具有实际价值。

After the anti-collision algorithm based on continuous collision bit detection is analyzed ,the computational method of the detection mode word is modified ,the mechanism of collision bit detection is improved ,and finally the circuit model for the an-ti-collision algorithm based on collision bit detection is descripted in Verilog HDL .The circuit is composed of a parallel pipelining read/write device and a collision bit detection controlling circuit in the tag .The simulation indicates that the circuit can detect the actual existing multiple continuous or non-continuous collision bit strings quickly and accurately .It works in parallel pipelining for reducing the collision slots and improving the efficiency ...
