【摘要】 本文在对RFID系统工作原理进行阐述的基础上,计算研究了阅读器发射频率和标签谐振频率的偏差与标签最小动作磁场强度之间的关系,进而分析了标签读写角度的限制对标签检测率的影响,讨论了提高标签检测率的两种方式:多标签法和多阅读器法,为RFID系统的设计及应用提供了一种有效的途径。更多还原

【Abstract】 On the basis of discussion of RFID system work principle,the relationship between least action magnetic field strength and difference of reader emission frequency and tag resonance frequency is studied and calculated.And then the effect of tag putting angle in magnetic field on tag detection is analyzed.Two methods of improving tag detection are discussed.They are named multi-tag and multi-reader.They provide a good way for design and applications of RFID.system.更多还原
