基于Wi-Fi Sensing的无感检测技术OA

With the popularization of smart home,the behavior perception of moving objects has become a hot technology.Compared with the traditional information detection technology,the new device independent passive intrusion detection based on Wi-Fi signal can detect and judge the behavior without any user intervention and without affecting the privacy security of personnel,which is significantly different from the use of camera or infrared detection,and has become a research hotspot.In this paper,the channel state information of the physical layer is collected based on the Wi-Fi chip platform,and the detection model related to the mobile carrier information is constructed.Based on big data analysis and intelligent algorithm,the relevant implementation scheme is given,and the waveform features are captured from the wireless channel based on experimental verification,which verifies the effectiveness of the scheme.The analysis of the results also provides a direction for further improvement of the follow-up accuracy.
