一种基于无源射频识别标签的消防员室内定位系统

消防员在地下建筑、无窗建筑、大型建筑物内,执行火情控制与人员搜救时,不可避免会遇到浓烟、黑暗、高温、陌生等情况,因此就需要精确的室内定位系统支持,已有的室内定位技术无法满足定位精度和长期部署的需求.本文提出了一种基于无源射频识别（RFID）标签的消防员室内定位系统,通过在消防员头盔内安装可变功率的RFID读写器,并将建筑物内读取的已经过精确标定的RFID标签信息回传到远程服务器进行计算处理,可实现建筑物外指挥员对室内消防员的实时精准定位和指挥功能.

An indoor positioning system for fireman based on passive RFID tag

In the underground building,windowless building,big building,the fireman often meet these conditions such as smoke,dark,high temperature,strange status when they control the fire or rescue,so the accurate support of indoor positioning system is very important.Existing technology of indoor positioning system is short,because it has been unable to meet the requirements of the accurate positioning and long-term deployment.Now,this paper explains a study about an indoor positioning system for fireman based on passive radio frequency identification （RFID） tag,it is the installation of variable power in the helmet in RFID reader,and the RFID tag information have been read in building will carry the accurate calibration to a remote server for processing,the purpose to realize the real-time accurate positioning and command functions to the indoor fireman.
