| 摘 要： | 应急疏散研究中的人员定位问题对于快速疏散人群和拯救被困人员具有重要的意义.为了确定Wi-Fi定位手段对于室内人员疏散的适用性,采用手持Wi-Fi设备和预设置的无线信号基准参考点,利用无线接收信号强度指数通过模式匹配的方式进行多人员定位的尝试.所得实验结果表明此方案的室内定位精度能达到5~7m.新方案所提供的定位精度能够区分室内多个体的移动路径,为相应疏散应用提供人员的动态位置信息描述.

| Abstract: | Locating respondent in the emergency evacuation is crucial for the egress of the crowd and rescuing of the trapped people.To address this issue,this paper summarizes existing research progress and discusses the feasibility of utilizing Wi-Fi devices and setting referenced points,and then combines pattern matching method with Received Signal Strength Indicator to produce positions of people without prior accurate surveying.The result shows we could generate acceptable initial position of the corresponding person in the interest area. |
