基于RFID的LANDMARC井下定位技术研究

Research of underground RFID-based LANDMARC location technology

概述了基于RFID技术的LANDMARC井下定位系统原理;针对井下多径效应导致的LANDMARC定位系统精度低的问题,从RSSI值的准确性、最邻近点的选取和权重公式3个方面总结归纳了LANDMARC系统改进方案;指出基于RFID的LANDMARC井下定位系统的研究方向为系统布局和核心定位算法。

Principle of underground RFID-based LANDMARC location system was briefly introduced For low location precision of LANDMARC location system caused by underground multi-path effect, improved schemes of the LANDMARC system were summarized form the view of accuracy of RSSI, selection of the nearest point and weight formula. Research directions of the underground RFID-based LANDMARC location system were put forward, which were system layout and central location algorithm.
