Description

Laser evacuation guidance method using deep learning {METHOD FOR GUIDING EVACUATION BY LASER USING DEEP LEARNING ALGORITHM}

The present invention relates to a laser evacuation guidance method, and more specifically, to a method for guiding an evacuation route by projecting a laser beam and guiding an evacuation route using deep learning in the event of a fire or power outage.

In general, guidance lights for promptly evacuating people to emergency exits in the event of an emergency, such as a fire or power outage, are obligatory in buildings of a certain size or larger, such as commercial facilities, public facilities, subways, and multi-use facilities.

Such a guide light is installed on the ceiling, floor, or floor of the aisle, and even if power to the building is temporarily cut off due to fire or power outage, it is turned on for a certain period of time so that people can easily find the emergency exit. It has a structure in which an induction display is printed on the board and a light bulb or fluorescent lamp is installed on the back side.

However, induction lamps usually employ fluorescent lamps with low luminous intensity, so that their function is lost because visibility is not secured in the event of a fire that is filled with smoke.

That is, the conventional evacuation guide light has a problem in that it is not easy to identify the location of the emergency exit and check the direction of evacuation with the naked eye because it is covered by the concentrated flame of the ceiling when a fire occurs.

Therefore, it frequently occurs that people in the area where the fire has occurred cannot evacuate to the evacuation site by referring to the guide light, resulting in many human casualties.
