Smart Wireless Movement Detection and Security Alert System

원문 (중국어)

A system and method of detecting if a person has fallen or is otherwise in distress within a defined region of interest. At least one Wi-Fi transmitter is provided that transmits Wi-Fi signals throughout a region of interest. Wi-Fi signals contain channel state information that is affected by motion patterns of objects within the region of interest. At least one Wi-Fi receiver is used for receiving the Wi-Fi signals that are propagating through the region of interest. The Wi-Fi receivers capture channel state information data streams that contain the changing channel state information of the Wi-Fi signals. The channel state information data streams are analyzed with convolutional neural networks and gated recurrent units to identify the motion patterns within the region of interest. An alarm condition is produced should the motion patterns match known motion patterns that correspond to a person falling or otherwise becoming compromised.
