摘　　要：针对图书馆需处理的图书量大,一般的反碰撞算法无法满足图书馆管理的实际需要,故对当前不同的反碰撞算法进行了分析和比较,提出了相对反碰撞效率比较高,并且在ISO/IEC 15693协议中相对容易实现的递减式动态时隙ALOHA反碰撞算法,以及来解决多标签碰撞问题。仿真结果表明,该算法在同时识别128张标签时依然高效,能够很好地满足图书馆管理的要求。In view of a large number of the book quantity to which the library needs to process,the ordinary anti-collide algorithm can not satisfy the actual management of libraries.The analysis and the comparison of the current different anti-collide algorithms are carried out.The progressively-decreased dynamic time slot ALOHA anti-collide algorithm,which has high anti-collide efficiency and is easy to be realized in ISO/IEC15693 protocol,is proposed to solve the multi-tags＇collision problem.The simulation result indicates that the algorithm still has high efficiency while 128 tags are distinguished simultaneously and can satisfy the request of library management.
