一种基于动态二进制的RFID抗冲突算法

An Anti-Collision RFID Algorithm Based on the Dynamic Binary

抗冲突是非接触式IC卡系统必须解决的问题.基于ISO/IEC14443A型标准推荐算法的抗冲突电路具有可靠性强的特点.从提高抗冲突速度和降低电路功耗的角度考虑,在此基础上提出一种改进的算法.功能验证与功耗模拟证明新算法显著提高了抗冲突速度,且电路的功耗也有一定程度的降低.

Anti-collision is necessary for the system of contactless IC card. To increase the anti-collision speed and reduce the circuit power dissipation, a new algorithm based on the dynamic binary is presented FPGA is used to verify the function of the circuit designed. Meanwhile, power dissipation simulation for the anti-collision circuit shows good performance.
