Description

OPERATION METHOD OF EMERGENCY FIRE EVACUATION GUIDANCE SYSTEM

The present invention relates to a fire evacuation route guidance system, and more particularly, to a method of operating the system for guiding an optimized evacuation route in case of a fire.

Recently, as the size of buildings has increased and diversified, interest in prevention facilities to minimize damage in case of fire is increasing. In addition, there is a growing interest in minimizing the loss of many lives and property damage due to a fire in a building.
In the event of a fire in a building, evacuees must escape the final exit by themselves with the ability to perceive the building's structure, such as guidance lights or sounds, according to the fire. In the process of escaping from such a building, evacuees try to move to the nearest passage or stair without accurately recognizing the location of the fire rather than the shortest distance to the exit, resulting in delays in the building where the fire has occurred. In this case, the damage caused by suffocation such as poisonous gas over time is greater than the immediate damage caused by the occurrence of a fire.
Therefore, in order to escape, it is most desirable to try to escape at an early stage of a fire, and if the fire occurs, many evacuees can succeed in escaping if they are guided to an optimal route.
On the other hand, the conventional guide light for guiding a fire path loses its function by flame or smoke, and it becomes more difficult for evacuees to find an escape route, resulting in a delayed outdoor escape time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an operating method of a fire evacuation route guidance system for quickly guiding evacuees to an optimal evacuation route in case of a fire.

Hereinafter, an optimal evacuation route selected from among preset evacuation routes according to the location of the fire will be described in detail.
Figure 4 is a simple building design for explaining the fire evacuation guide route system shown in Figure 2 in more detail. Referring to FIG. 4 , the fire evacuation guidance route system 200 according to an embodiment of the present invention may guide an optimal evacuation route selected from among preset evacuation routes according to a fire location.
Although the case of using the light sources shown in FIG. 2 is described in FIG. 4 , the case of using the light sources shown in FIGS. 1A to 1C may also be included.
2 and 4, when a fire occurs on the third floor of a building consisting of five floors, the controller 230 selects an evacuation route that guides the evacuees of the first and second floors to the first floor, and the light sources ( 221 , 222 , 223 , 224 ) may display a guide to the emergency exit on the first floor. The controller 230 may select an evacuation route leading to the rooftop shelter while preventing the evacuation of the 4th and 5th floors from being guided to the 3rd floor where the fire occurred, and display guidance toward the rooftop shelter. The controller 230 may select an evacuation route leading to the first floor or rooftop shelter according to the location of the fire on the third floor, and may operate the light sources 221 , 222 , 223 and 224 accordingly.
5 and 6 are plan views of the third floor of FIG. 4 for explaining the fire evacuation guidance route system shown in FIG. 2 in more detail.
5 and 6 are plan views of the third floor of the building shown in FIG. 4 , in which six zones are arranged facing each other three on the left and right. The first emergency staircase ST1 is positioned on the upper left side, and the second emergency staircase ST2 is positioned on the lower right side.
Referring to FIG. 5 , when a fire occurs in the uppermost area AR1 on the left, the controller 230 (refer to FIG. 2 ) makes the light sources 220 of the first emergency stair ST1 flicker and fire While preventing movement to the poor area AR1 in advance, the rest of the light sources 220 may be operated to guide them in the direction of the second emergency stair ST2.
Referring to FIG. 6 , when a fire breaks out in the area AR2 located in the middle of the right side, the controller 230 turns the light sources 220 of the second emergency stair ST2 into a flashing state to cause the fire to occur in the area AR2. The remaining light sources 220 may be operated to guide in the direction of the first emergency stair ST1 while preventing movement to the stairwell in advance.
Since the light sources 220 are composed of light emitting diodes, the brightness (brightness) is excellent in flames and smoke, so that a guide display can be clearly displayed on the floor. An evacuee can easily find an optimal evacuation route through the guidance signs 220a , 220b , 220c projected by the light sources 220 . Therefore, it is possible to quickly escape in the early stage of the fire.
