基于RFID的室内定位系统设计

Design of Indoor Location System based On RFID

根据室内定位存在NLOS现象和电磁波的多径传播特点,结合信号强度(RSS)和几何空间距离之间对应的经验关系,利用最邻近参考标签的来完成定位,设计一种基于RFID的室内定位系统。该系统精度好,稳定性强,能够很好地移植到各种实际场合。

Accorded to the phenomena of NLOS and multipath propagation of electromagnetic waves during indoor location, an indoor location system was designed based on RFID, which combined with the empirical relationship between RSS and geometric space distance, and used nearest neighbor reference tag to finish location. This system reveals good precision and stability, and can be easily ported to a variety of practical environment.
