摘要

在本文中，我们提出了一种使用超高频RFID无源标签在室内环境下的低成本定位系统。它可以用来定位陌生建筑中的物体或人。对信号的功率分布、传播条件和环境因素进行了详细的研究。我们的系统采用了地标参考标签网格。标签RSSI (Received Signal Strength Indication，接收信号强度指示)是我们改进的K最近邻算法的主要值。对室内环境下的路径损耗模型进行了分析。通过Path Loss模型构建参考位置的误差图和精度，帮助选择相应的K个参考位置。

Indoor Localization System Based on Passive RFID Tags

In this paper, we present a low-cost localization system using UHF RFID passive tags in indoor environments. It can be used to locate objects or people in an unfamiliar building. The signal power distribution, propagation conditions and environmental factors will be studied in more detail. Landmark reference tag grid is applied in our system. The tag RSSI (Received Signal Strength Indication) is the main value for our improved K nearest neighbor algorithm. Path Loss models for an indoor environment are also analyzed. The error map and the accuracy of the reference positions are constructed through the Path Loss model for helping to choose corresponding K reference positions.
