摘要

针对射频识别（RFID）系统中为了满足多类应用、异构网络、多样性服务等应用而部署的多阅读器和多应答器

导致数据识别、传输时延和信号完整性等性能下降的问题

研究了一种适用于多阅读器应答器系统的基于中继传感器的协同防碰撞算法。根据系统发生数据碰撞的三种情形

结合数据碰撞角度和碰撞效应权重

提出一种有效避免数据碰撞的中继传感器结构设计方案;设计了适合于RFID系统中继传感器协同合作的外围电路;结合系统覆盖区内三类辐射元的信号汇聚

提出了基于中继传感器的协同防碰撞算法。实验结果表明:在读取时隙和传输时延等方面

所提协同防碰撞算法明显优于传统的ALOHA算法。

Abstract

Aiming at performance decling problem of data recognition

transmission delay and signal integrity

caused by deployed multiple reader and multiple transponders to meet application of multi-class applications

heterogeneous networks

diversity of service system

in radio frequency identification（ RFID） system

a collaborative anti-collision algorithm suitable for multi-reader / transponder system based on relay sensor is studied.According to the three situations of data collision occur in system

combined with data collosion angle and weight of collosion effect

put forward an effective data collision avoiding design scheme of relay sensor structure; design a peripheral circuit suitable for RFID system relay sensor collaboration; combined with signal convergence of three kinds of radiation element in system covers area

present a collaborative anti-collision algorithm based on relay sensor. Experimental results show that in reading time slot and transmission delay

the proposed collaborative anticollision algorithm is obviously superior to the traditional ALOHA algorithm.
