Description

Evacuation guidance device for easy identification even in fire situations{Apparatus for guiding exit in fire}

The present invention relates to an evacuation exit guidance device, which is easy to identify even in a fire situation.

In general, an emergency exit is an entrance provided in a building so that people in the building can evacuate in case of a fire, and it is required to be installed in a building where many people such as schools, companies, theaters, apartments, etc. are active. In order to quickly and safely exit the building through such an emergency exit, emergency guidance lights are installed in the emergency exit and the passage leading to the emergency exit to guide people to the emergency exit.

In the event of a disaster such as a fire, machinery and equipment and evacuation equipment used for evacuation are largely divided into evacuation equipment and guidance signs for guidance lights. At this time, the evacuation device is used as an emergency auxiliary evacuation means when it is impossible to evacuate to the ground through an emergency exit. As described above, taxi lights and guidance signs are intended to inform the location of the emergency exit and the direction of evacuation, and should be easily identifiable by anyone and can be distinguished from a distance.

However, due to the structural characteristics of modern buildings that are becoming increasingly complex and large, if the power is cut off due to an explosion in the event of an actual fire, or if it is difficult to identify an emergency guidance light due to smoke, the building is not a safe escape route even if the emergency exit is found. The incidence of life-threatening accidents is increasing due to the inability to escape.

In this way, when a fire breaks out in a building, victims are confused and their judgment is blurred and they cannot find the proper location of the entrance. Therefore, it can be said that the most precautionary measure is to reduce personal injury by urgently moving evacuees to safe evacuation sites.

However, due to safety insensitivity and economical requirements, investment interest in firefighting equipment is low, and the existing firefighting system also has parts to be improved, but improvements are not being made. With the increasing trend of large-scale fire accidents and the resulting injuries in domestic and foreign countries, the government and related organizations are also aware of the importance of firefighting equipment and systems, but they have not yet shown concrete willingness to resolve them.

Existing emergency exit guidance devices are configured to display only the direction of the emergency exit close to the guidance light without considering the location of the fire. Therefore, in the event of a fire in a building, evacuees recognize only the fire situation by fire alarm or sound and evacuate to the nearest emergency exit.

However, the evacuees have a problem in that they suffer more damage while swaying around because the identification of the guidance light installed on the top of the emergency door is not understandable in the smoked state of the fire.

The technical problem of the present invention is that it is difficult to identify a guide light as the concentration of toxic gas increases in a fire situation using an LED projector. Accordingly, by installing an LED projector on the floor and shining on the guide light, evacuation in a fire situation is made easier and quicker. It is to make it easy to identify the location of the evacuation exit so that evacuation is possible, and since it uses an LED projector, it is possible to illuminate the corridor or illuminate the location of the evacuation passage.

An embodiment of the present invention is a detection sensor installed at a position of a certain height of the inner wall of a building and detecting smoke caused by a fire; And an evacuation exit that is buried and installed on the floor of a building, but when smoke is detected through a detection sensor, the evacuation exit guidance image recognizable to the naked eye is irradiated toward the evacuation exit exit door in a different direction than usual when no fire has occurred. It may include a guided projection unit.

The evacuation exit guidance projection unit, a transparent plate covering the buried groove formed on the floor of the building; An LED projector installed in the buried groove to irradiate an evacuation exit guidance image that the evacuee can recognize with the naked eye toward the evacuation exit evacuation door; A direction angle adjustment driver for driving the irradiation direction of the LED projector; And a control module for controlling the direction angle adjustment driving body to irradiate an evacuation exit guidance image toward the evacuation exit evacuation door.

The control module may perform irradiation by changing the irradiation direction of the evacuation exit guidance image and the irradiation direction of the evacuation exit guidance image when a fire is detected through the detection sensor.

The control module controls the evacuation exit guidance image to be irradiated on the upper side of the evacuation gate evacuation door in normal times, and when a fire is detected through the detection sensor, the evacuation exit guidance image is controlled to be irradiated on the lower side of the evacuation exit evacuation door. can do.

The control module may differently control a position irradiated to the lower side of the evacuation exit door according to the amount of smoke detected by the detection sensor.

The control module may control a lower position irradiated to the lower side of the evacuation exit as the amount of smoke detected through the detection sensor increases.

The transparent plate is implemented as a cover body that can be opened and closed, and the control module, when the amount of smoke detected by the detection sensor exceeds a preset threshold, evacuates the evacuation exit guidance image with the transparent plate open. You can investigate towards the door.

According to an embodiment of the present invention, it is possible to identify the location of the evacuation exit guidance lamp by illuminating the LED projector in case the concentration of the toxic gas increases in a fire situation when the concentration of the toxic gas is high. In addition, it is easy to understand the evacuation route when evacuating by making it easy to recognize the location of the evacuation exit door, and to minimize personal injury by expediting evacuation. In addition, the LED projector can be used to illuminate when the evacuation route is dark, and it can also be used to illuminate the location of a fire extinguisher necessary for fire extinguishing or a guide sign.

However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, and is provided to completely inform the scope of the invention to those of ordinary skill in the art to which the present invention pertains. As such, the invention is only defined by the scope of the claims.

The present invention enables rapid evacuation by installing the LED projector 220 above the entrance door of the evacuation exit and installing the evacuation exit guidance light on the floor to facilitate identification even in a fire situation so that the guidance light can be identified through the projector in a fire situation, As a result, human damage can be minimized. In the prior art, an evacuation guide light is attached to the upper part of the evacuation door, so that the location of the evacuation door can be known, and because LED lights are used a lot, it is possible to identify it even in a dark place. However, when the fire intensifies and the concentration of toxic gas increases, it becomes difficult to identify the guidance lamp. The advantage is that by placing an evacuation guide light on the floor using the LED projector 220 and illuminating it, the gases that are scattered on the upper side due to the concentration of toxic gases are attached to the bottom and evacuate without obstructing the view, so that the entrance is checked.

To this end, the evacuation exit guidance device of the present invention, which is easy to identify even in a fire situation, is installed at a position of a certain height on the inner wall of a building, and a detection sensor 100 that detects smoke caused by a fire, and is embedded in the building floor to detect When smoke is detected through the sensor 100, the evacuation exit guidance projection unit 200 controls the direction in which the evacuation exit guidance image recognizable with the naked eye is irradiated toward the evacuation exit evacuation gate, different from usual when no fire has occurred. do. It will be described in detail below.

The detection sensor 100 is installed at a position of a predetermined height on the inner wall of a building and detects smoke caused by a fire. The detection sensor 100 is preferably located at the top of the passage 10, and when the detection sensor 100 detects the smoke concentrated at the top of the passage, the detection signal detected by the detection sensor 100 is an evacuation exit. It is transmitted to the guided projection unit 200.

Transmission of the detection signal can be performed through wired or wireless communication means, and wired communication methods such as Ethernet, Universal Serial Bus, IEEE 1394, serial communication, and parallel communication May be used, and wireless communication methods such as infrared communication, Bluetooth, home radio frequency (RF), and wireless LAN may be used.

The evacuation exit guidance projection unit 200, as an image irradiator installed on the floor of a building, performs a function of irradiating an evacuation exit guidance image that the evacuee can recognize with the naked eye toward the evacuation exit evacuation door.

To this end, the evacuation exit guidance projection unit 200 may include a transparent plate 210, an LED projector 220, a direction angle adjustment driver 230, and a control module 240, as shown in FIG. 2. .

The transparent plate 210 is a transparent plate plate covering the buried groove formed on the floor of a building, and a plate made of various transparent materials such as a tempered glass plate and a transparent plastic may be used. It is preferable that the transparent plate 210 is formed of a heat-resistant material that can withstand high temperature heat to protect the LED projector 220. Therefore, the evacuation exit guidance image emitted from the LED projector 220 passes through the transparent plate 210 and is irradiated toward the evacuation exit evacuation door.

The LED projector 220 is installed in a buried groove, which is a fixed space formed by being buried in the floor of a building, and performs a function of irradiating an evacuation exit guidance image that the evacuee can recognize with the naked eye toward the evacuation exit evacuation door. Preferably, the LED projector 220 is formed to have a spherical shape, and maintains a state rotated in the front upward direction so that image information is output through the evacuation exit door.

The direction angle adjustment driver 230 performs a function of driving the irradiation direction of the LED projector 220. Inside the buried groove, it is combined with the LED projector 220 by a hinge and can be rotated upward or downward, and the projection direction is adjusted to output an evacuation guide image, which is image information, to the upper or lower side of the evacuation gate in front of the passage. .

The control module 240 controls the direction angle adjustment driving body 230 to irradiate an evacuation exit guidance image toward the evacuation exit evacuation door.

Further, the control module 240 makes the irradiation direction of the evacuation exit guidance image different from the irradiation direction of the evacuation exit guidance image when a fire is detected through the detection sensor 100 in a different manner to investigate.

That is, when controlling to irradiate an evacuation exit guidance image to the upper side of the evacuation exit evacuation door as shown in 3 in normal times, on the other hand, when a fire is detected through the detection sensor 100, the evacuation exit as shown in FIG. The guidance image is controlled to be irradiated on the lower side of the evacuation gate.

Therefore, it is possible to check the location of the emergency exit in normal times, and in case of a fire, it is possible to secure a visible distance due to smoke by illuminating the bottom of the door. Since the smoke gets thicker as it goes up, the evacuation guide light installed above the existing door is illuminated under the door to easily inform the location of the evacuation exit.

On the other hand, as the amount of smoke increases when a fire occurs, the smoke is filled from the upper side of the passage, making it difficult to recognize an evacuation exit guidance image output through the evacuation exit guidance projection unit 200.

In consideration of this, the control module 240 of the present invention may differently control a position irradiated to the lower side of the evacuation exit door according to the amount of smoke detected through the detection sensor 100.

For example, as shown in FIG. 5, as the amount of smoke detected through the detection sensor 100 increases, the position irradiated to the lower side of the evacuation exit is controlled to be lower. Therefore, as the amount of smoke increases, it is irradiated to the lower side of the evacuation gate, so that evacuees can easily recognize the location of the evacuation gate, even if there is a large amount of smoke.

For reference, the irradiation direction according to the amount of smoke may be stored and utilized as a DB (DataBase) form of a storage body. Storage: SSD drive (Solid State Drive), Flash memory (Flash Memory), CF card (Compact Flash Card), SD card (Secure Digital Card), SM card (Smart Media Card), MMC card (Multi-Media Card) ) Or a memory stick (Memory Stick) as a module capable of inputting and outputting information, and may be provided inside the device, or may be provided in a separate device.

On the other hand, when the transparent plate 210 is present, no matter how transparent the transparent plate 210 is, the clarity of the evacuation exit guidance image is affected.

Therefore, when too much smoke is generated due to a fire, it is necessary to remove the transparent plate 210 and implement an evacuation exit guidance image to be directly irradiated toward the evacuation exit evacuation door.

To this end, the transparent plate 210 is implemented as a cover body that can be opened or closed. A driving motor is mounted on one side, and a shaft formed on the upper portion of the transparent plate 210 is coupled to the driving motor so that the transparent plate 210 can be opened or closed.

Therefore, the control module 240, when the amount of smoke detected through the detection sensor 100 exceeds a preset threshold value, the transparent plate 210 is opened and the evacuation exit guidance image is irradiated toward the evacuation exit door. Also, even in a fire situation, the identification of the evacuation gate can be made easier.

The embodiments in the description of the present invention described above are presented by selecting the most preferable examples to aid the understanding of those skilled in the art from among various possible examples, and the technical idea of the present invention is not necessarily limited or limited only by this embodiment. , Various changes and modifications and other equivalent embodiments are possible within the scope of the technical spirit of the present invention.
