RFID高频读写器防碰撞算法研究

摘要

Purposed to improve the performance of the RFID （Radio Frequency Identification） High-Frequency read/write device.The binary search algorithm was introduced.The bite frame anti-collision was studied on in detail ,which is based on the binary search algorithm and followed the ISO/IEC 14443A protocol.The bite frame anti-collision can verify the performance of anti-eoUision of HF read/write device availably. This method to solve the high-frequency RFID anti-collision problems and improve performance of HF read/write device has important application significance and directive significance%基于对RFID（无线射频识别，Radio Frequency Identification）高频读写器防碰撞性能提高的目的，介绍了二进制搜索算法原理，并基于二进制搜索算法详尽研究了一种符合ISO／IEC14443A规范的比特帧防碰撞算法，比特帧防碰撞算法能有效的实现高频读写器的防碰撞功能。此方法为解决RFID高频防碰撞问题，提高高频读写器性能具有重要的实用意义和指导意义。
