【摘要】：基于对智能手机的WiFi无线定位技术的研究,设计了一种地震灾害中面向生命探测的无线定位系统。通过对被压埋手机的定位,间接探测被压埋人员的位置。首先阐述了对实际废墟信道下无线WiFi2.4G信号的测量,得到在废墟复杂环境下的路径损耗。其次从定位系统的客户端和服务器端两方面介绍了WiFi定位系统的结构及各模块实现,介绍了客户端数据采集、存储、滤波、转发的具体实现,服务器端数据接收、定位算法的实现及位置坐标的显示。该系统为地震等灾害救援中的人员定位提供了一种新的解决方案,使得对大面积灾害被压埋人员准确而快速定位成为可能。
[Abstract]:Based on the research of WiFi wireless location technology of smart phone, a wireless location system for life detection in earthquake disaster is designed. The location of the buried person is indirectly detected by the location of the buried mobile phone. Firstly, the measurement of wireless WiFi2.4G signal under the actual ruins channel is described, and the path loss in the complex ruins environment is obtained. Secondly, the structure and modules of WiFi positioning system are introduced from two aspects of client and server, and the realization of data acquisition, storage, filtering, forwarding and data receiving in server are also introduced. The realization of location algorithm and the display of position coordinates. The system provides a new solution for personnel location in earthquake and other disaster rescue, and makes it possible to locate the buried personnel accurately and quickly.
