文章通过对IAMS算法的分析，提出了一种基于连续碰撞位探测（CCBD ）的防碰撞算法。在CCBD算法中引入连续碰撞位探测机制，并把标签碰撞分为单独位碰撞和连续位碰撞两种情况进行处理。连续碰撞位探测机制能够准确获得连续碰撞位的实际存在情况从而避免了空闲时隙以及不必要的碰撞时隙的产生。理论分析和实验仿真表明，CCBD算法克服了IAMS算法的不足，在标签识别过程中表现出良好的性能。

Through the analysis of IAMS algorithm ,this paper proposed a zero idle timeslot anti-collision algorithm which is based on continuous collision bit detection (CCBD ) .CCBD algorithm introduced continuous collision bit detection mechanism ,and divided tag collision into individual bit collision and continuous bits collision to process .CCBD algorithm can obtain the actual exis-tence of the continuous collision bits by using continuous collision bit detection mechanism ,thereby avoiding the generation of idle timeslots and unnecessary collision timeslots .The theoretical analysis and experimental simulation show that the CCBD algorithm has overcome the shortage of IAMS algorithm and has a good performance during RFID process .
