UHF频段RFID系统防碰撞算法研究

Studies on Anti-collision Algorithms Used in UHF RFID System

防碰撞技术是决定RFID系统性能的关键因素之一,特别是UHF频段,防碰撞性能决定着多目标的识别率、识别速度。本文着重研究UHF频段RFID系统防碰撞解决方案和算法改进问题,探讨盘存周期内总时隙数的选取,并对系统效率进行仿真,提出简单易行的提高系统效率的方法。

Anti-collision technology is one of the key factors that determine RFID system performance, especially for UHF RFID, multiple object identification depends on Anti-collision performance. This paper emphatically studies the solution and improvement of anti-collision algorithm, and the selected number of invention cycle slots, updating of Q will be discussed. We propose a method to achieve higher system efficiency based on the simulation.
