Indoor ChildAnti-Loss System Based on Smart Devices
To address the frequent issue of children getting lost in large indoor spaces,a real-time alert and tracking system has been developed based on readily available smart devices.This sys-tem comprises two components:the parent-end and the child-end.The parent-end utilizes a sm-artphone as a platform to analyze WiFi signal strength and transmit data,providing real-time monitoring,warning,and location guidance functions.Meanwhile,the child-end utilizes smart-watches or smart wristbands as wearable devices,employing deep learning technology to analyze data collected by built-in sensors and estimate the child's location and activity information.Ex-perimental results demonstrate the system s ability to accurately detect and alert potential in-stances of child wandering,facilitating prompt localization and tracking.This solution offers an effective approach to mitigate indoor child loss incidents.
