【摘要】：较一般室外人员定位系统而言,室内环境的复杂性和多变性一直考验着室内人员定位系统的适用性,室内环境可能从人口密集的城市环境转变到无人值守的偏远地区。本课题重点开展了无WiFi信号覆盖的远距离无人值守场所的室内定位技术研究,设计了基于无线传感器网络的远程室内人员定位系统,该系统可实现基于WiFi信号的远距离室内人员定位。本文在通过分析室内人员定位技术与无线传感器网络国内外研究现状的基础上,根据系统方案设计要求,设计了以无线传感器网络为硬件实现平台的远程室内人员定位系统。该系统以无线传感器网络节点为信息获取手段,以WiFi无线技术为组网传输方式,以无线AP、无线网桥为传输工具。利用LabVIEW软件设计了远程监测平台。传感器节点包括STM32微处理器、内置A/D采集模块、SD存储模块和WiFi传输模块。信息获取之后用TDOA算法完成对目标的位置定位和轨迹绘制。在完成系统整体设计后,对系统进行实验。实验结果表明,目标的定位精度和数据的传输距离等功能达到系统方案设计要求。
[Abstract]:Compared with the general outdoor personnel positioning system, the complexity and variability of indoor environment always test the applicability of indoor personnel positioning system. Indoor environment may change from densely populated urban environment to unattended remote area. The remote indoor personnel positioning system based on wireless sensor network is designed. This system can realize the remote indoor personnel location based on WiFi signal. Based on the analysis of indoor personnel location technology and domestic and international research status of wireless sensor network, according to the system design requirements, A remote indoor personnel positioning system based on wireless sensor network (WSN) is designed, which takes wireless sensor network node as information acquisition means and WiFi wireless technology as network transmission mode. The remote monitoring platform is designed by using LabVIEW software and wireless bridge is used as transmission tool. The sensor node includes STM32 microprocessor. After the acquisition of information, TDOA algorithm is used to complete the position location and trajectory drawing of the target. After completing the overall design of the system, the system is tested. The experimental results show that, The positioning accuracy and data transmission distance of the target meet the requirements of the system scheme design.
