针对仅利用无线信号源和其发射信号强度定位会丢失待测位置与信号源之间固有空间关系的问题,提出了利用已知位置接收信号源发射的无线信号强度测量未知点的低成本室内定位方法。该方法深入分析了待定位点和无线信号源以及信号覆盖范围之间的空间关系,充分利用RCC-8空间关系模型进行无线定位。实验结果表明,采用这种融合空间拓扑关系的基于无线信号强度的室内定位方案能够优化定位流程,并在测得位置中反映待测点和信号源之间的相对空间关系。
Aiming at the problem of using the wireless signal source and its transmitted signal strength positioning to lose the inherent spatial relationship between the measured position and the signal source, a low cost indoor positioning method is proposed for measuring the unknown point of the wireless signal transmitted by the known position receiving signal source method. The method deeply analyzes the spatial relationship between the location to be fixed and the wireless signal source and the coverage of the signal, and makes full use of the RCC-8 spatial relationship model for wireless location. The experimental results show that the indoor positioning scheme based on wireless signal intensity using this fusion topological relationship can optimize the positioning process and reflect the relative spatial relationship between the measured point and the signal source in the measured position.
