摘要:
标签碰撞是射频识别系统的关键问题,它增加了系统的时间开销和无源标签的能量消耗,降低了系统识别速率。文章提出了一种增强型Q参数混合防碰撞算法-EQH算法,该算法通过检测一定数目的标签响应时隙的状态,对其中的连续碰撞时隙和空闲时隙的信息进行分析,快速调整帧的大小,同时标签中引入一个特殊寄存器,使分配到每个时隙的标签能够被快速识别,减少了时隙的消耗。性能分析和仿真结果显示,该算法能够快速、准确地估算标签的数目,且具有较高的系统识别率
Abstract:
Tag collision is a key issue of radio frequency identification system. It increases the time overhead of the system and the energy consumption of the passive tag,reducing the identification rate. An enhanced Q parameter hybrid anti-collision algorithm ( EQH) was proposed by detecting and analyzing tag response time slots state in consecutive slots to quickly adjust the size of the frame,at the same time,a special register is introduced into the tag so that it can be identified quickly and reduce the consumption of the time slot. Perform-ance analysis and simulation results show that the proposed algorithm is able to quickly and accurately estimate the number of tag labels and has higher identification efficiency
