(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view showing the basic configuration of an emergency evacuation guidance system according to the present invention. In the figure, reference numeral 11 denotes a laser oscillation device that oscillates a laser beam B. As shown in FIG. The laser oscillation device 11 is arranged so as to oscillate a laser beam B in the direction of emergency evacuation, for example, toward an emergency evacuation exit (emergency exit) 12 .

It is desirable that the laser oscillation device 11 be placed at a relatively high position, for example, above the wall W so that it can be easily seen by evacuees.

Further, the laser oscillation device 11 has a built-in operating power source so that it operates even when power supply to the building is stopped.

Reference numerals 13 and 14 are abnormality detection devices that detect abnormalities that occur within the building and issue abnormality detection signals, such as smoke detectors 13 installed on the ceiling, earthquake detectors 13 installed on the wall or floor. A sensor 14 and the like are used. In addition to this, a temperature detection sensor, a gas detection sensor, etc. can also be used in combination.

These abnormality detection devices 13 and 14 are each controlled by the control device 1.
5, and an abnormality detection signal is sent to the control device 15. Further, the laser oscillation device 11 is also connected to the control device 15, and an operation command signal based on an abnormality detection signal is input from the control device 15.

A general push button type alarm 16 is further connected to the control device 15, so that an abnormality detection signal can be sent to the control device 15 even when operated by a person.

Next, the operation of this embodiment having such a configuration will be explained.

When an abnormality such as a fire occurs in a building, the abnormality is first detected by the abnormality detection devices 13 and 14, and an abnormality detection signal is sent to the control device 15. The control device 15 that received this signal sends an operation command signal to the laser oscillation device 11,
The laser oscillation device 11 automatically operates. Laser beam B is oscillated and directed in the direction of emergency evacuation.

A person attempting to evacuate in an emergency can see the direction of this laser beam B and know the evacuation route. In order to clearly indicate the evacuation route, it is effective, for example, to expand the width of the emitted laser beam B in the direction of evacuation. Also, please evacuate along laser beam B. It is also effective to make an emergency broadcast with the following content:

Since the laser beam B has the property of traveling straight without attenuating its optical power, it can reach a long distance even if smoke occurs, and the evacuation route will not be lost. Also,
The laser beam's light trail is reflected by smoke particles, making the evacuation route more clearly visible.

As described above, according to this embodiment, people can be safely guided to the emergency exit even in a building filled with smoke.

Although this embodiment shows an example in which the control device 15 is placed separately, the control device 15 can also be integrated into the laser oscillation device 11.

FIG. 2 is a schematic perspective view showing another embodiment of the present invention,
An example is shown in which there are obstacles along the emergency evacuation route.

For example, if there is an obstacle A in the middle of the evacuation route, or if there is a protrusion C in the position where you want to install the laser oscillation device 11,
The laser beam B from the laser oscillation device 11 is sent to the emergency exit 12.
If it is not possible to directly oscillate the laser beam B, an optical scanner 18 is used to change the optical path of the laser beam B, so that the laser beam B can reach the target location.

The optical scanner 18 includes a mirror that repeatedly rotates and a motor that rotates the mirror, and can make the laser beam B incident on the mirror and reflect it in a predetermined direction. Further, it is desirable that the power source (battery) for the optical scanner 18 is built-in in case of a power outage.

The optical scanner 18 is placed in the optical path of the laser beam B from the laser oscillation device 11, and the rotation angle of the mirror of the optical scanner 18 is controlled so that the reflected light beam from the optical scanner 18 is directed toward the emergency exit 12. There is. This optical scanner 1
8 is electrically connected to a control device (not shown) together with the abnormality detection device and the laser oscillation device 11, as in the embodiment described above.

Therefore, in this embodiment, when the abnormality detection signal is emitted by the abnormality detection device, the laser oscillation device 11 is activated to oscillate the laser beam B, the optical scanner 18 is activated, and the mirror emits the laser beam B. Expand to a specified width and mark the target area (e.g. emergency exit 1).
2) Orient in a direction.

This makes it possible to change the optical path of the laser beam B, and even if there is an obstacle A in the optical path, the laser beam B for evacuation guidance can be easily seen and reach the predetermined destination. can.

Note that it is also possible to use an ordinary fixed mirror instead of the optical scanner 18 as a means for changing the optical path of the laser beam B. However, if the optical scanner 18 is used, the narrow laser beam B of 1 to 5 mm and 1 degree can be expanded to a width that is easily visible. Furthermore, since the surface of the mirror of the optical scanner 18 is manufactured with high precision, there is little scattering of light, and even if the surface becomes slightly dirty, there is an effect that the reflection performance of the laser beam B will not be degraded.

FIG. 3 is a schematic perspective view showing another embodiment of the present invention.

This embodiment is applied when the evacuation route (for example, a corridor) is curved.

A laser oscillation device 11 is disposed above the wall surface W so as to oscillate a laser beam B along the evacuation route. Also, the bending angle of the evacuation route, for example, the bending angle of the wall surface W,
In the middle of the optical path of the laser beam B, an optical scanner 18 equipped with a rotating mirror and a small motor is arranged so as to direct the laser beam B in the evacuation direction. In this embodiment as well, the laser oscillation device 11, the abnormality detection device, and the optical scanner 18 are electrically connected to a control device (not shown), as in the previous embodiments.

According to this embodiment, the optical path of the laser beam B from the laser oscillation device 11 is bent along the evacuation route by the optical scanner 18 at each corner of the evacuation route, and the laser beam B is caused to reach the emergency exit 12. Therefore, by moving along the optical path of this laser beam B, the evacuee can surely reach the emergency exit 12.

In this embodiment as well, an ordinary fixed mirror can be used instead of the optical scanner 18 as a means for changing the optical path of the laser beam B.

FIG. 4 is a schematic perspective view showing another embodiment of the present invention.

This embodiment is used, for example, to illuminate a green character display that says "emergency exit" as stipulated by the Fire Service Act.

In this embodiment, in the middle of the optical path of laser beam B,
An X-axis optical scanner 18a and a y-axis optical scanner 18b having rotation axes perpendicular to each other are provided, and the laser beam B is swung in the X-axis direction and the X-axis direction by vibration of each mirror to produce a beam width. is made possible.

This makes it possible to illuminate a predetermined area,
Text information indicating "emergency exit" can be clearly read even from a distance. This makes it easier to find emergency exits, especially if there is heavy smoke.

FIG. 5 shows an example of application of the above-described embodiment with an X-axis optical scanner 18aSy-axis optical scanner 18b. In this embodiment, an X-axis optical scanner 18a and a y-axis optical scanner 18
By controlling the rotational frequency of b, the letters ``Emergency Exit'' (19) are drawn on the evacuation door.

Furthermore, by controlling the rotational frequency of the optical scanners 18a and 18b, it is also possible to draw arbitrary character information. In addition to evacuation doors, text and graphic information can also be drawn on walls, smoke, and spaces.

By depicting text information in this way, it is possible to give evacuees a greater sense of psychological security.

FIG. 6 is an explanatory diagram showing still another embodiment of the present invention. In this embodiment, by controlling the frequency of the optical scanner 18, the width of the laser beam B is expanded in the direction of evacuation, and the evacuation is carried out in the band of light formed by this laser beam B. A wavy shape S indicating the direction, for example, a continuous pattern of folded lines as shown in FIG. 6 is provided.

By providing such a waveform S, the direction to evacuate can be known more reliably.

FIG. 7 is a schematic perspective view showing another embodiment of the present invention.

In this embodiment, a laser oscillation device 11 is disposed near an emergency exit 12, which is an exit for emergency evacuation, and is configured to oscillate a laser beam B toward the inside of the building. Further, an optical scanner 18 is disposed at a corner of the evacuation route, so that the laser beam B emitted from the laser oscillation device 11 can reach deep inside the building.

According to this embodiment, since the laser beam B is oscillated from the emergency exit side, the direction toward the emergency exit 12 can always be indicated no matter how thick the smoke is. In other words, even if the laser beam B does not reach a far distance due to insufficient optical power, the direction of the most important emergency exit 12 will be reliably indicated regardless of the difference in the laser beam reach distance. .

Furthermore, since the width of the laser beam B gradually becomes narrower toward the emergency exit 12, it is psychologically effective in pointing in the direction of escape. Furthermore, since the light source escapes in a direction where the light source is strong, this also has the effect of giving a psychological sense of security.

FIG. 8 is an external perspective view showing the protective cover 21 of the optical scanner 18. The optical scanner 18 placed in the middle of the evacuation route is likely to be damaged if an object or the like collides with it. For this reason, it is desirable that the optical scanner 18 be covered with a protective cover 21. As shown in FIG. 8, this protective cover 21 is preferably provided with a notch 21a in a portion corresponding to the path through which the laser beam B passes.

〔Effect of the invention〕

As explained above, by oscillating a highly transparent laser beam in the direction of emergency evacuation or toward the inside of a building from the emergency exit side, it is possible to provide emergency evacuation guidance information without obstructing the view due to smoke, etc. Can be done. Furthermore, by using an optical scanner in combination, it becomes possible to change the optical path of the laser beam and use the laser beam for multiple purposes, thereby expanding the scope of application of the emergency evacuation guidance system.

The present invention can be installed in buildings where many people gather, such as department stores, hotels, office buildings, and underground malls.
When an abnormal situation occurs, it is highly effective as an auxiliary device for artificial emergency evacuation guidance.
