SYSTEM FOR PREVENTING MISSING CHILD

摘要

PURPOSE: A system for preventing the generation of a missing child is provided to verify a child as a missing child when the child is separated from a guardian as much as a pre-set distance. CONSTITUTION: A sensor for a guardian(110) transmits first data containing first identifying information. A sensor for a child(120) transmits second data containing second identifying information. A relay sensor group(130) transmits a first position tracking necessity information based on the first data and a second position tracking necessity information based on the second data. A managing server(140) tracks the position of the sensor for the child based on the first and the second position tracking necessity information. A distance between the sensor for the guardian and the sensor for the child is verified.
