GROUP ABANDONMENT DETECTION SYSTEM USING BLUETOOTH MESH NETWORK COMMUNICATION METHOD

摘要

Provided in one embodiment of the present invention is a system for sensing a deviated member from a group, wherein the device is attached to a target (elderly, infant, mentally challenged) who is difficult to control and has a high risk of disappearance during a group activity, and upon an occurrence of a deviated member from a group, the occurrence of the deviated member is notified using a Bluetooth mesh network communication method. The system for sensing a deviated member from a group according to one embodiment of the present system is characterized in that the system can perform a terminal-to-terminal communication through a mesh network terminal-to-terminal communication using one terminal which can be commonly used in a group, if there is a terminal having a terminal-to-terminal distance in the group outside a communication distance, the system includes a terminal for outputting a deviation member warning to terminals of all members, and a deviation member is detected through a terminal-to-terminal communication (mesh network), wherein the terminals include: a warning generation unit for outputting a deviation warning when a member′s terminal out of the communication distance occurs during a communication in the group through the terminal-to-terminal communication; and, a method of each terminal, if there is a new member, automatically generating and storing a group through an initial one to two minutes communication of terminals.
