Description

  The present invention relates to a system for guiding evacuees in an emergency such as a fire.

  In buildings where many people go in and out, evacuation guide lights are installed to indicate the route of evacuation in an emergency.

  Conventional evacuation guide lights have pictorial design displays depicting the refugees on a translucent board, or letters such as “emergency exit” or “EXIT”, or both, and a small fluorescent lamp from the back. It is illuminated and is attached to the upper part of the wall surface or suspended from the ceiling.

  As auxiliary means for the evacuation guide light, there is a small evacuation guide light attached to the lower part of the wall surface or a small evacuation guide light installed on the floor.

  Japanese Patent Application Laid-Open No. Hei 6-282773 discloses a “fire notification facility” for displaying a fire occurrence position and a current position of an evacuee when a fire occurs. However, this facility simply displays the location of the fire occurrence and does not have an evacuation guidance instruction function.

Japanese Patent Laid-Open No. 6-282773

  Such a conventional evacuation guide light is attached to the upper part of the wall surface or suspended from the ceiling, but the location of the evacuation route is clear in normal times when evacuation guidance is not necessary, but an evacuation guide light is required. When fires occur most often, smoke fills in the upper part and the hepatic kidney escape light is not visible.

  In addition, the conventional evacuation guide light can make the resident know the evacuation route well, but since it does not know the evacuation route, it is not possible to give the evacuation guidance instruction to an outpatient who needs the evacuation guidance most. Has a point.

  Because the evacuation guide light attached to the bottom of the wall must be small, it is difficult to read the display. There is a problem that the function is limited.

  Since the evacuation guide lights installed on the floor require a transparent plastic cover for protection, they must be small and many people step on them, so the transparent cover is damaged and displayed. Has the problem of becoming unclear.

  In addition, since the display related to the entire conventional evacuation guide light is fixed, even if it is necessary to change the appropriate evacuation guidance route according to the disaster situation, it is possible to give an appropriate evacuation guidance instruction. It has a problem that it cannot be done.

  Furthermore, not only conventional evacuation guide lights are ineffective for low vision and blind people, but also low visibility because of the use of small fluorescent lights as light sources for conventional evacuation guide lights. And have problems.

  The present application aims to provide an evacuation guide light that solves these problems, and has the following general configuration.

  The evacuation guide lamp of the invention according to the present application is not attached to the upper part of the wall surface or suspended from the ceiling, but is installed on the floor surface, the step board of the staircase, or the stairs. By doing in this way, even if smoke is filled in the upper part at the time of a fire occurrence, since there is little smoke on the floor, the evacuation guide light will not be invisible.

  The evacuation guide light is formed on the floor in the case of a flat floor, in the case of a staircase, in a vertically formed kick when the evacuation direction is upward, and horizontally when the evacuation direction is downward Installed on the tread.

  The display is performed by a light emitting diode instead of a combination of a conventional translucent display panel and a fluorescent lamp. By using a light-emitting diode, it is possible to change the display contents at any time, and even if it is necessary to change the appropriate evacuation guidance route according to the disaster situation, an appropriate evacuation guidance instruction is given be able to.

  When a light-emitting diode is used as a display element, even if the transparent cover made of resin is damaged by many people due to the high visibility unique to the light-emitting diode, the visibility in the smoke is good. Secured.

  In addition, since the floor, the step board of the staircase, or the kick of the staircase has a considerably large area, it can be made large, and a sufficient amount of information can be provided.

  Furthermore, by adding a voice function, it is possible to perform sufficient evacuation guidance for a weakly sighted person or a blind person. This voice function is effective not only for weakly sighted and blind people but also for visually impaired people when visual field is poor due to smoke or power outage.

  Visibility is enhanced by performing blinking display, intermittent display, or moving image display.

Action

  Since the evacuation guide light of the invention according to the present application is installed on the floor, the stairs, or the stairs board, the evacuation guide light can be visually recognized even if smoke is filled in the upper part at the time of the fire.

  In addition, the display contents can be changed at any time, and in combination with the fact that the display can be enlarged, various displays can be performed.

  Furthermore, by incorporating a speaker, an effective evacuation guidance instruction can be given not only to a visually impaired person such as a visually impaired person or a blind person but also to a visually healthy person even when the visual field is poor due to a power failure or smoke.

Embodiments will be described with reference to the drawings.
FIG. 1 is an embodiment of the present invention applied to a flat floor. In this figure, 1 is a floor, 2 and 3 are evacuation guide lights according to the present invention. The display parts of these evacuation guide lights 2 and 3 are composed of a matrix of light emitting diodes, embedded in the floor surface, and the surface is protected by a transparent plate such as bulletproof glass.

  Although the display of this embodiment is a horizontal writing display, it can also be a vertical writing display.

  The evacuation guide lights 2 and 3 are arranged at intervals at which both can be visually recognized in the smoke. When the evacuation direction is from the position of the evacuation guide light 2 to the evacuation guide light 3, the evacuation guidance is performed. A display such as the lamp 3 is also given to the evacuation guide lamp 2. Needless to say, when the evacuation direction is reversed, the evacuation guide light 2 is displayed on the evacuation guide light 3.

  The display is the simplest, but it remains lit, but it draws the attention of the evacuees, displays blinking and intermittent displays to improve visibility, and displays a movie such as an arrow to clearly indicate the evacuation direction I do.

  The surface of the evacuation guide light embedded in the floor is covered with bulletproof glass, etc., but the light emitting diode light is covered with a hemispherical transparent resin even when the bulletproof glass surface is scratched. The visibility is difficult to decrease.

When a built-in speaker is installed in the evacuation guide light and the evacuation guidance instruction is audible from this speaker, even if it is a visually impaired person as well as a visually impaired person who is blind or blind, a poor visual field due to smoke or blackout Effective evacuation guidance instructions can be given.
In that case, since the voice can be recognized from a distant place and it may be difficult to hear if the same sound is emitted from a distant place at the same time, the speaker is not built in all the displays but only in a limited display. Build in.

  The audio display is specifically a warning sound “Ping-Pawn” or “This is the stairs from here” or “Emergency fire, please go to the A1 exit. Provide voice guidance.

  The display unit is composed of, for example, eight display elements composed of a 16 × 16 dot LED matrix, and characters, marks, etc. can be displayed by turning on or off each dot. Further, depending on the LED used, in the case of a red and green two-color LED, three colors of red, green and orange can be displayed. It is also possible to perform color display by using red, green and blue LEDs.

  Further, when it is desired to make the display contents more complicated, a matrix display of 16 × 16 dots or more can be adopted, or a larger display can be adopted so that an image can be displayed.

  It is also possible to use a pictogram indicating an evacuation guideway that is conventionally used as the display content.

  The LED character display can be alerted by changing the color or blinking. In addition, the display method can be displayed by combining large and small characters, flowing a sentence from right to left, and flowing an arrow in the direction of an arrow.

FIG. 7 shows an evacuation guidance system using the evacuation guidance light of the invention according to the present application.
In the case of a fire, etc., the best condemnation route must be selected depending on the location. In the conventional single display, there is a possibility that the user will be guided to a dangerous place. In order to improve this, the present invention sets a condemnation route in advance according to the fire occurrence site, and instructs an optimum evacuation route based on the set information when a fire occurs.

  In the evacuation guidance system of FIG. 7, an optimum evacuation route is instructed according to the location of the fire. Here, 41, 42, 43... Are fire sensors such as smoke sensors and heat ray sensors, 51, 52, 53..., Fire alarms, 31 a control unit, and 32 a fire. Display data storage units 61, 62, and 63 for storing display information corresponding to evacuation routes that have been selected in advance according to locations where sensors and fire alarms are installed are indicators set in various places. 33 are input terminals.

  When the fire detector indicated by reference numeral 42 detects a fire, the information is transmitted to the control unit 31. Based on the fact that the fire detector 42 senses the fire, the control unit 31 selects the optimum evacuation route according to each location, takes the display content suitable for each location from the display data storage unit 32, and The contents are sent to the respective display devices 61, 62, 63. The display devices 61, 62, 63 display according to the received display data. For example, in the case of a fire in a subway station, the display device 61 displays “Proceed to Exit A1”, the display device 62 displays “Fire ahead, return”, the display device 63 displays “Go straight and proceed to Exit A5”, and the like. By this, it is possible to instruct the most suitable blame taxiway according to the location of the fire.

  Fire conditions change over time. Corresponding to this situation change, the instruction content of evacuation guidance is changed.

  Input of characters and the like is input via an interface such as RS-232C or Ethernet. The input contents are selected and displayed as necessary.

  The input terminal 33 is used when operating manually. In addition to emergency display, facility guidance and advertisements are input via the input terminal 33 during normal times. For example, as cautions that it is a staircase, there are information such as `` Stairs from here, foot notice '', `` Here is left-hand traffic '', etc. It is also possible to display advertisements such as “early”.

  Because the stairs are stepped, accidents caused by whispering or stepping off are likely to occur. Therefore, not only does an accident occur when evacuating when visibility is poor, such as a fire, but the evacuee acts cautiously with fear of whispering or stepping out, so the evacuation behavior may be limited, resulting in delayed evacuation. .

FIG. 2 shows an embodiment in which the invention according to the present application is applied to stairs in order to avoid such a situation.
In this figure, 4 is a staircase, 5 is a tread that is a horizontal plane, 6 is a kick that is a vertical plane, 7 is a display provided on the tread 5, and 8 is a display provided on the kick 6.
In the embodiment shown here, “exit ↑” is displayed on the indicators 7 and 8. These displays are displayed only when evacuation guidance is required, but advertisements are displayed at other times.

  The indicator 7 provided on the tread board 5 is displayed when the evacuation direction is a direction to go down the stairs, and the indicator 8 provided at the kick 6 is displayed when the evacuation direction is a direction to go up the stairs. By displaying in this way, an evacuation route can be reliably instructed to the refugee.

  The indicator provided on the kick-in is visible in front of the evacuees going up the stairs, so the visual effect is high. Also, since the steps of the staircase are illuminated, the position of the staircase can be determined even in the dark, and the unevenness that causes the stuttering can be determined.

  Since the indicator provided on the tread board is visible to the feet of the evacuees who go down the stairs, the position of the stairs can be determined even in the dark, and the unevenness that causes the whirling can be determined.

  The indicators 7 and 8 can be integrally formed in a shape such as a box, and only a necessary display surface can be exposed to the tread plate 5 and the kick-in 6.

FIG. 3 shows another embodiment in which the invention according to the present application is applied to stairs.
When the evacuation direction is only the direction of going up the stairs, there is no need to provide an indicator on the tread board 5.

In this figure, 11 is a staircase, 5 is a tread which is a horizontal plane, 6 is a kick which is a vertical plane, and 12 is a display provided on the kick 6. In this embodiment, the indicator 12 is provided only on the kick 6.
In addition, when it intends to perform other displays, such as an advertisement, it is also possible to provide an indicator on the tread board 5.

FIG. 4 shows still another embodiment in which the invention according to the present application is applied to stairs.
If the evacuation direction is only the direction of going down the stairs, there is no need to provide an indicator on the kick 6.

In this figure, 16 is a staircase, 5 is a tread that is a horizontal plane, 6 is a kick that is a vertical plane, and 17 is an indicator provided on the tread. In this embodiment, the indicator 17 is provided only on the tread board 5.
In addition, when it intends to perform other displays, such as an advertisement, it is possible to provide a display also in the kick 6.

The indication does not necessarily have to be provided on all treads and / or kicks.
In still another embodiment shown in FIGS. 5 and 6, the indicators 22 and 23 are provided on the kick 6 and / or the tread 5 at appropriate intervals.

  In that case, as shown in FIG.5 and FIG.6, the installation work burden is reduced by making the indicators 22 and 23 adjoin. Further, when the configuration of FIG. 6 is adopted, the indicators 27 and 28 can be integrally formed in the shape of a box or the like so that only a necessary display surface is exposed to the tread plate 5 and the kick-in 6.

  Moreover, although the display has been described based on LEDs, a display device such as a liquid crystal display or EL may be used.

  In the embodiment, the display is provided on the floor and the stairs, but it can be installed on the wall or ceiling.

  As described above, according to the present invention, an appropriate evacuation guidance instruction can be given according to the situation at the time of emergency. In addition, because the walking situation of the stairs changes, it is possible to call attention at places where accidents are likely to occur.

Furthermore, since the indicator is provided at the foot, the influence of smoke is small and the display can be clearly recognized.
Furthermore, it can be used for facility guidance and advertisement display during normal times.
