基于ISO 15693的RFID中间件反冲突算法设计与实现

Design and Implement of RFID Middleware Anti-collision Algorithm Based on ISO 15693

反冲突作为射频识别（radio frequency identification，RFID）技术的基础，引起了各种相关机构的重视，各种读写器与标签之间的反冲突算法层出不穷，但由于算法的复杂性，许多读写器往往只具有冲突探测功能，而没有实现完全的反冲突。利用ISO 15693-3协议中关于冲突探测机制和反冲突算法描述，设计并实现了对读写器进行反冲突控制的算法。实验表明：该反冲突控制算法达到了高效反冲突的目的。

Anti-collision as the foundation of RFID （radio frequency identification）, is attracting more and more researchers＇ attention. Various anti-collision algorithms have been put forward. However, because of algorithms＇ complexity, lots of readers only have the ability of collision detection actually. The paper designs and implements such an anti-collision algorithm （host controlling reader algorithm） based on the collision detection mechanism and anti-collision algorithm description of ISO 15693-3. Experiments show that our algorithm is correct and effective.
