Autonomous Decentralized Evacuation Guidance System for Building Fires

For smooth and reliable evacuation in the event of a fire, it is necessary for each evacuee to take into account "control of the number of people using the same exit and escape route and timing" and "rescheduling that adapts to the ever-changing fire situation" without the need for a management server or an external power supply. This study aimed to construct an autonomous evacuation guidance system that uses screen displays and voice guidance on a dedicated device in each room of an operational facility. In this system, all information is transmitted only as beacons. This paper describes the communication between a fire alarm and a dedicated device, sharing of fire information between the dedicated devices, self-position estimation of the dedicated device, and an evacuation guidance experiment that integrates them.
