  • intensive fire alarms are set within at least 3 floors on each of the upper and lower floors and within the range of 3 rooms on the left and right, centering on the received report location, and notify the fire situation through user fire alarms provided in each room. And, you can guide the evacuation route.
  • the server calculates the optimal evacuation route based on the reported location, and can be distributed and guided to a plurality of self-driving emergency evacuation devices. Therefore, it is possible to guide efficient evacuation by preventing evacuees from being driven to a self-driving emergency escape device in one location.
  • the server has fire department and police department information.
  • the server can report the occurrence of a fire while providing information on the report location to the fire department and the police station.
  • the alarm 154 may be connected to the sensing unit 151 by wire, and generates a fire when the descending drive of the footrest unit 130 is detected. At this time, the alarm 154 may be distributedly arranged in the corridor or the room of each collective building.
