摘要
RFID技术被广泛地用于电子身份识别和跟踪定位。首先,介绍RFID定位系统构成及应用场景,回顾了主流的RFID定位算法以及采用这些算法的定位系统,并对这些定位系统进行比较分析;然后,指出影响RFID系统定位精度的因素,并根据当前RFID定位技术应用领域,给出RFID定位系统的发展趋势。结论:与其它定位技术相比,RFID定位具有极强的发展潜力;虽然RFID技术是可用于从低频到微波的各个频率,但在到具体应用时,关键还是要选择一个正确的工作频率,以更好地适应不同的应用场景。
Radio frequency identification （RFID） is widely used for electronic identification localization and tracking. First- ly,the authors give a brief introduction of the components of RFID and application scene, and summarize the mainstream localization algorithm and RFID localization systems that use these algorithms. Then we make comparative analysis of posi- tioning system. Secondly,we point out the factors that affect the accuracy of positioning RFID system, and according to the current application of RFID positioning technology, they give the future development trend of it. Conclusion ： compared with other positioning technology, RFID positioning has great development potential, while RFID technology is available from low frequency to the microwave,but taking into account the specific application, the key is to choose a proper working frequency for different applications.
