Real-time behavior identification method and system based on WIFI signal

The invention discloses a real-time behavior identification method and system based on a WIFI signal, and the method comprises the steps: extracting the physical layer information of the WIFI signal through a user terminal, and automatically judging the behavior of an indoor user according to the change condition of the WIFI signal. Working in a sheltered environment and a night environment is facilitated, and action recognition based on wireless signals has the advantages that equipment does not need to be carried, through-wall scanning can be achieved, and personal privacy is guaranteed. 本发明公开了一种基于WIFI信号的实时行为识别方法与系统，通过用户终端将WIFI信号的物理层信息进行提取，根据WIFI信号的变化情况，可以自动判断出室内用户的行为；不仅方便在遮挡环境中、夜晚环境中工作，并且基于无线信号的动作识别具有无需携带设备、可穿墙扫描、保障个人隐私等优点。
