随着城市化进程的快速推进,室内定位的应用前景广阔,尤其在一些特定场合的实时性和必要性已经日趋显著,其研究意义非常大。通过对现有室内定位技术的比较,提出了基于MEMS和WSN技术相融合的应急室内定位系统方案,从系统架构、硬件实现、软件算法等方面进行阐述。基于MEMS和WSN技术相融合的室内定位系统不依赖于现有的Wi-Fi系统,能够在突发事件发生后快速架设、硬件通用性好、能够通过不断优化软件算法持续提高系统性能,是未来室内应急定位的一种有效手段。
With the rapid progress of urbanization, the application prospect of indoor positioning is very broad. Especially in some special occasions, the real-time nature and necessity have become increasingly significant, and the research is of great significance. Based on the comparison of existing indoor positioning technology, a scheme of emergency indoor positioning system based on MEMS and WSN technology is proposed. The system architecture, hardware implementation and software algorithm are described. The indoor positioning system based on MEMS and WSN technology does not depend on the existing Wi-Fi system and can be quickly set up after an emergency occurs. The hardware has good generality and can continuously improve the system performance by continuously optimizing software algorithms. It is the future Indoor emergency positioning of an effective means.
