摘要
为了解决超高频射频识别读写器在碰撞时隙标签无法识别的问题,本文遵循ISO18000-6C协议标准设计了一款高性能的超高频读写器系统,并对读写器的主要性能指标进行了仿真与测试,最后验证了设计的可行性。本系统采用模块化设计,系统工作频率为860-960 MHz,输出功率可达+30 d Bm。通过引入新型防碰撞算法,使得读写器在碰撞时隙也可以一一识别标签,相比于现有读写器,标签的识别时间降低了约29%,标签识别率提高了约25%。
In order to solve the problem that the UHF RFID reader can not be identified in the collision time slot,this paper designs a high-performance ultra high frequency reader system according to the ISO18000-6C protocol standard.The main performance indexes of the reader are simulated and tested,and the feasibility of the design is verified at the end of the last.The systm adopts the idea of modular design.The system’s operating frequency is 860-960MHz and output power can reach+30dBm.By introducing a new anti-collision algorithm,the reader can also identify the label one by one in the collision time slot.Compared with the existing readers,this design reduces the identification time of the tags by about 29%and improves the tag recognition rate by about 25%.
