Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to hospitals, hotels, inns,
The present invention relates to a disaster prevention guidance display system that appropriately guides evacuation when a fire occurs in a relatively large-scale facility used by a large number of unspecified people such as an underground mall for 24 hours.

[0002]

2. Description of the Related Art In public facilities such as hotels and underground malls, it is obligatory to install guide lights for indicating evacuation exits and emergency exits under the Fire Service Law. These guide lights are installed for the purpose of guiding people to an evacuation exit or an emergency exit when a disaster such as a fire occurs. In addition, since the supply of electric power is not guaranteed in the event of a disaster, a battery for backup is provided so that the above-mentioned guide light can be turned on for a certain period of time even in a power failure state. With such a facility, it is possible to evacuate to a safe evacuation port in the event of a disaster by using the guide light display as a guide even during a night power failure.

[0003]

A problem with the above-described guide light is that the display content of the guide light is constant, and therefore the guide direction of the evacuation exit may be inappropriate depending on the disaster occurrence position. . For example, in a city-type high-rise hotel, when a fire erupts from the downstairs at night, it may be more appropriate to evacuate from an evacuation exit on a detour route away from the fire site, rather than evacuating from a nearby emergency staircase.

FIGS. 5 (a) and 5 (b) explain such a situation. FIG. 5 (a) shows the installation situation of a conventional guide sign that indicates an evacuation route on a certain floor. In the figure (a), K1 to K4 are guide signs provided at important points of the evacuation guide route, and E is a guide light indicating an evacuation gate. The guide signs K1 and K4 are shown to evacuate from the stairs 1 at the P1 position provided in the building, and the guide signs K2 and K3 evacuate from the emergency exit at the P2 position using the emergency stairs 2. The sign is shown.
In such a situation, a fire broke out from the downstairs of the building and P1
If you want to evacuate from the location A near the emergency exit, follow the instructions on the guide signs K1 and K4 and follow the shortest route S2 to P1.
It is assumed that you will evacuate downstairs from the stairs 1 in the building where you are located.
It is considered that using the emergency stairs 2 to evacuate from the emergency exit at the location is more appropriate as an evacuation route because it is not involved in the fire below. That is, if the display of the guide signs K1 and K4 is K1 'and K4' shown in FIG. 5 (b), this object can be achieved.
Impossible.

The present invention has been made in view of the above circumstances, and appropriately guides evacuation in the event of a disaster in a relatively large-scale facility used by a large number of people such as hospitals, hotels, inns, and underground malls. The purpose is to provide a disaster prevention guidance display system that can reduce human damage.
