中文摘要：
为全面、客观评价射频识别（radio frequency identification,RFID）系统可靠性性能,在分析RFID系统工作原理的基础上,给出基于标签识别率的RFID系统的可靠性定义和三种可靠性指标测度定义,分析了这三种可靠性指标测度间的关系;分析了影响RFID系统可靠性的关键因素,包括无线信道误码率对识别率的影响、标签碰撞对识别率的影响,由此提出了RFID系统可靠性计算的一般模型.仿真结果表明：提出的RFID系统可靠性计算的一般模型是合适、可行的,有利于RFID系统可靠性分析、设计和性能评估.
英文摘要：
The definition on the reliability of RFID（radio frequency identification） system which is based on the identification probability of tag and three kinds reliability index measures are given on the foundation of analysing RFID principle to evaluate reliability performance of RFID system comprehensively and objectively.In this paper,relations between three kinds reliability index measures are analyzed.Key factors including radio channel bit error rate and tags collision effects on identification probability affecting reliability of RFID system are analyzed,and the general models of calculating reliability of RFID system are presented.Simulation results show the models are suitable,feasible,and convenient to analyze,design,and evaluate reliability of RFID system.
