摘要
防碰撞技术是RFID系统的关键技术之一,MCRF250无源RFID芯片具有防碰撞功能,采用基于FSK脉冲调制方式的碰撞检测方法,通过软、硬件设计,可以构建一个具有防碰撞功能的简单的RFID系统。
Anti-collision technology is one of the key technologies of RFID system. The passive RFID chip of MCRF250 has the function of anti-collision, the anti-collision detection method, which baced on the modulation of FSK, and through designs of the software and hardware, a simple system that has the function of anti-collision can be constructed.
