Description

Fire escape route guidance system {EMERGENCY FIRE EVACUATION GUIDANCE SYSTEM}

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

Recently, as the size and variety of buildings have increased, there has been a growing interest in prevention facilities to minimize damage in the event of a fire. In addition, there is a growing interest in minimizing the loss of lives and property damage due to fires in buildings.

In the event of a fire in the building, the evacuator must escape the final exit by himself or herself through the building's induction light or sound, or the perception of the structure of the building. In the process of escaping these buildings, the evacuator attempts to move to the nearest passage or stairway without accurate recognition of the location of the fire, not the shortest distance to the exit, resulting in a delay in the fired building. In this case, the damage caused by suffocation such as toxic gas over time occurs more than the immediate damage caused by the fire.

Therefore, in order to escape, it is most desirable to try to escape in the early stage of the fire, and even if the fire is advanced, many evacuators can succeed if they lead to the optimal path.

On the other hand, the conventional induction lamp for guiding the fire path loses its function by flames or smoke, and the evacuator becomes more difficult to find an escape way, which causes a problem of delaying the escape time of the outdoors.

The problem to be solved by the present invention is to provide a system for quickly guiding the evacuator to the optimal evacuation route in the event of fire.

Referring to FIG. 4, the fire evacuation guide path system 200 according to an exemplary embodiment of the present disclosure may guide an optimal evacuation path selected among evacuation paths preset according to a fire location.

4 illustrates a case of using the light sources shown in FIG. 2, but may also include a case of using the light sources shown in FIGS. 1A to 1C.

2 and 4, in the event of a fire in the third floor of the five-storey building, the controller 230 selects an evacuation path for guiding the evacuators of the first and second floors to the first floor, and the light sources ( 221, 222, 223, and 224 may provide guidance signs for the emergency exit on the first floor. The controller 230 may select the evacuation route leading to the rooftop shelters while preventing the evacuation of the 4th and 5th floors to the 3rd floor where the fire has occurred, and may display a guidance display toward the rooftop shelters. The controller 230 may select an evacuation route leading to the first floor or the rooftop shelter according to the fire location on the third floor, thereby operating the light sources 221, 222, 223, 224.

5 and 6 are plan views of the third floor of FIG. 4 for explaining the fire escape guide path 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, with six zones arranged facing each other three to the left and right. The first emergency stairs ST1 are positioned at the upper left side, and the second emergency stairs ST2 are positioned at the lower right side.

Referring to FIG. 5, when there is a fire in the area AR1 located at the top of the left side, the controller 230 (see FIG. 2) causes the light source 220 of the first emergency stairs ST1 to flash and fire. The remaining light sources 220 may be operated to guide in the direction of the second emergency stairs ST2 while preventing movement to the poor area AR1.

Referring to FIG. 6, when a fire occurs in the zone AR2 located in the middle of the right side, the controller 230 causes the light sources 220 of the second emergency stairs ST2 to blink, thereby causing the fire zone AR2 to fire. The rest of the light sources 220 may be operated to guide in the direction of the first emergency staircase ST1 while preventing movement to the fuel cell.

Since the light sources 220 are made of light emitting diodes, the brightness of the light sources 220 may be excellent in flames and smoke, and thus the guides may be clearly displayed on the floor. The evacuator can easily find the optimal evacuation path through the guide marks 220a, 220b, 220c projected by the light sources 220. Therefore, it is possible to escape quickly at the beginning of the fire.
