针对无线射频识别（RFID）系统中的标签碰撞问题，提出一种基于转换码的双时隙防碰撞算法BSCC。根据标签附加码的信息，标签在不同的时隙响应阅读器。同时该方法通过编码器编码用转换码表示标签识别码，使阅读器更容易读取碰撞信息，对标签进行准确识别。通过数学分析，准确地描述了BSCC算法识别标签所需的时隙数。仿真结果表明，BSCC算法消除了阅读器识别的空闲时隙，减少系统通信量，提高了标签的识别效率。

To solve the tag collision problem in Radio Frequency Identification (RFID) system, a bi-slot RFID anti-collision al-gorithm based on conversion code, called BSCC, is proposed. According to the tags additional code information, reader response tags in different time slots. And the method used conversion code instead of the tag identification code by encoder coding. It maked reader easier to read collision information to accurately identify the tags. Through mathematical analysis, it accurately predicted the total number of time slots required for the tags identification in BSCC algorithm . Simulation results show that the BSCC algorithm eliminates the idle time slots, reduces the communication bits, improves the tags identification efficiency.
