基于快速部署的室内多楼层定位算法研究

Research of Indoor Multi-storey Localization Alogorithm Based on Quick Deployment

传统的GPS系统在室内由于墙和障碍物的阻隔无法很好地生效,因此需要完善的室内定位系统,弥补定位领域最后100m的不足。然而当前国内外的主流算法大多是基于水平方向的室内定位,有关垂直方向定位方法的研究较少。为此,提出一种基于快速部署的室内多楼层定位算法,实现在大楼内精确的纵向多楼层定位和设备的实时、按需部署。该算法的核心是多楼层差分算法,通过接收来自不同楼层信号,加以差分计算差值的分布来区分楼层。仿真实验结果表明,该算法能够精确地定位楼层。

The traditional GPS is hard to do localization in indoor environment due to the complicated walls and obstacles. The mainstream of localization alogorithm is conducted on horizontal direction,and method on vertical direction is still a new topic. This paper presents an on-demand indoor multi-storey localization alogorithm,which can be fingerprint-free and deployed rapidly and on-demand in a multi-storey building. On vertical direction,it proposes Multistorey Differential（MSD）alogorithm,the main idea of which is to differentiate the RSSI from different floors to distinguish the exact floor of test point. It conducts both simulation and practical experiments to prove the accuracy of this alogorithm.
