Child Safety Tracking System

Child Safety Tracking System

This technology is an integrated location tracking and monitoring mechanism that tracks the positions of sensors worn by guardians and children via a sensor network composed of multiple relay sensors. A management server monitors the distance between them in real-time, and in the event of a child going missing, a safety robot is dispatched along the shortest path to the child's location to collect and transmit video and audio data.

Existing GPS-based technologies are unable to track locations in signal-shadowed areas such as indoors or underground, while RFID-based technologies have limitations due to short transmission ranges, requiring the dense installation of numerous readers and resulting in high physical infrastructure costs.

This technology works by having a group of relay sensors receive signals from sensors held by the guardian and the child, which are then transmitted to a management server that calculates their positions and measures the distance between them. If a child goes missing, the management server calculates the shortest path for a safety robot and issues a movement command, allowing the robot to arrive on-site to capture and transmit video and audio data. Applicable to logistics, service robots, and autonomous driving platforms, this system improves the efficiency and accuracy of child safety by providing real-time location tracking and early detection of potential missing child scenarios.

Key Features:

• A guardian sensor that transmits first data containing first identification information
• A child sensor that transmits second data containing second identification information
• A relay sensor group that identifies and transmits information required for tracking the second location of the child sensor based on the second data
• A child safety system further comprising a safety robot that transmits audio to the management server.
