中文摘要: 随着无线局域网应用和广泛部署,基于RSSI信号强度指纹匹配定位方法,以其不需添加额外硬件设备成为室内定位技术研究热点,但信号波动会引起较大的定位误差. 本文提出一种区域划分的RSSI定位方法,先利用信号强度对区域进行划分,再对信号指纹数据库匹配移动设备位置. 最后通过实验证明,该方法在百分之25th、50th和70th距离误差值分别是1.25米、2.25米和4.75米,能很好地减小由信号波动引起的定位误差,满足工程应用要求.
Abstract:With the widespread and deployment of wireless LAN, the RSSI signal strength fingerprint location technology, without needing to add extra hardware in indoor environment, becomes hot research. But large fluctuations signal will cause errors in location. This paper proposes a zoning RSSI location method, using Wi-Fi signal strength to divide regions, and then uses signal fingerprint database matching mobile device aera. Finally, the experiment shows that the 25th, 50th and 70th percentile values of the location distance error are 1.25 m, 2.25 m and 4.75 meter, which can reduce signal fluctuations caused by the location errors.
