Description

Technology Field

[0001] The present invention relates to a movement path notification system that supplements and enhances visual or auditory means for guiding movement paths to emergency exits or fire hydrants for escape in a fire situation. Background Technology

[0002] Modern buildings require systems that guide the location of emergency exits and fire hydrants to facilitate rapid evacuation in the event of a fire. Such systems play a crucial role in reducing casualties, particularly in public spaces or large-scale buildings. This method utilizes currently widely used emergency exit and fire hydrant indicator lights to visually indicate their locations.

[0003] While these technologies may be effective for basic guidance, they reveal limitations in providing practical route guidance in situations where multiple people must evacuate simultaneously due to complex building structures and indicator lights on each floor (such as parking status and emergency call devices resulting from technological advancements). In particular, when a building is filled with smoke due to a fire or when lights are off, it is difficult for users to recognize the optimal path to an emergency exit using existing fire safety indicator lights. In such environments, it is crucial not only to clearly identify the locations of emergency exits or fire hydrants but also to guide users along safe and efficient evacuation routes.

[0004] Conventional technology primarily used methods to guide the location of emergency exits and fire hydrants using small, fixed indicator lights and wall-mounted emergency exit guide lights. However, this method makes it difficult for evacuees to identify the optimal route in real time while moving. In particular, wall-mounted emergency exit guide lights cannot provide dynamic guidance, limiting users' ability to intuitively understand the path between their current location and the emergency exit.

[0005] Furthermore, since existing systems focus on simple "location display" rather than route guidance, there is a high likelihood of causing confusion for users in buildings with complex internal structures or multi-story layouts. For example, in large shopping malls, hospitals, or multi-use facilities, simply displaying "emergency exit signs" is insufficient to clearly convey evacuation routes to people.

[0006] These problems can be addressed by directly marking the actual paths leading to emergency exits or fire hydrants on the floor. In particular, a method that projects arrow-shaped lights onto the floor to intuitively guide movement can provide users with clear visual information even in smoke or darkness. However, conventional technology rarely applies such methods, and there is a lack of dynamic and real-time adaptable guidance systems.

[0007] Another limitation of conventional technology lies in the visibility of guidance systems. Existing small indicator lights are visible only from specific angles, and it is difficult to control the direction or intensity of the light. Consequently, if a user is far from an emergency exit or located in a space such as a hallway or corner, it becomes difficult to perceive the small indicator lights. To solve this, technology is required that dynamically controls the light to enable the user to quickly recognize the direction of guidance based on their current location.

[0008] As such, while conventional technology may be suitable for basic location guidance, it has limitations in guiding actual movement paths in emergency situations such as fires or in supporting users to move quickly. Prior art literature

[0028] First, the terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0029] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Meanwhile, in the drawings below, the size of specific components may be relatively exaggerated to aid in understanding the invention, and where there is no need to distinguish between multiple identical components, they may be represented as a single representative component.

[0031] The present invention will be described in detail below with reference to the attached drawings.

[0032] A fire-time movement guidance system according to one embodiment of the present invention includes, as shown in FIG. 1, lighting (4, 5, 6), an emergency power source (1) that supplies power to the lighting (4, 5, 6), and a control unit (2) that controls the lighting (4, 5, 6) and the emergency power source (1).

[0033] In particular, the lighting (4, 5, 6) is installed so that it can be identified from a distance even in emergency situations such as a fire, as can be seen in the photos of FIGS. 4 and FIGS. 5, by making the perimeter of the emergency exit (E), the top of the fire hydrant (S), or the wall-mounted location of the sprinkler manual operation panel (S) (SVP, Super Visory Panel).

[0034] For reference, the SVP is a control switch panel that can manually operate the solenoid valve when the sprinkler's pre-action valve is not activated in the event of a fire. Therefore, since the location of this SVP can be extremely important when a fire occurs, lighting of a specific color can be installed on it as well, as shown in FIG. 6.

[0035] In emergency situations such as a fire, the indoor space may be filled with smoke from combustion, causing a loss of sense of direction and making it difficult to find the emergency exit (E), leading to confusion. In response to this, there is a trend in the development of technology that guides movement paths by installing floor lighting extending from the emergency exit (E) on the indoor floor, as shown in the photograph in Fig. 1.

[0036] However, installing a lighting system along the indoor floor in this way requires significant cost, time, and effort, and the process of tearing up the indoor floor can also result in significant noise and depreciation of the building.

[0037] In this regard, the present invention introduces lighting that brightly illuminates necessary element points at precise locations to enable rapid evacuation in the event of a fire, without the need to construct any long-distance power and lighting systems that require tearing down and embedding the building's exterior walls or floors. This allows for guidance of movement paths in the event of a fire to be provided at a low cost and by simple means.

[0038] At this time, the lighting (4, 5, 6) can be composed of bar-shaped LED lights as can be seen in FIGS. 4 to 6, an emergency exit light (4) attached to the edge of the emergency exit (E), a fire hydrant light (5a, 5b) attached to all or part of the edge of the fire hydrant (P) and the top of the column where the fire hydrant is installed so that it can be identified from a distance even when a vehicle is parked and remains lit at all times, and an SVP light (6) attached to part of the sprinkler manual operation panel (S) and remains lit at all times.

[0039] Here, the emergency exit light (4), fire hydrant light (5a, 5b), and SVP light (6) can be installed with different colors, such as green and red in FIGS. 4 to 6, respectively. Thus, the green light, which evokes safe escape, allows one to intuitively know that it is an emergency exit (E), and the red light of the fire hydrant, given that firefighting equipment is typically red, allows one to intuitively know that there is a fire hydrant.

[0040] And, referring to FIGS. 2 and FIGS. 3, an inspection remote control (3) capable of remotely flashing the emergency exit light (4) is provided, and the control unit (2) may be provided with a remote control signal receiving unit (23) that receives a signal from the remote control (2) and a control circuit that connects the emergency power supply (1) to the emergency exit light (4).

[0041] At this time, the control circuit may include a normal contact (21) which is a contact that normally connects the emergency power supply (1) to the light using the inspection remote control (3), a fire contact (22) which automatically connects the emergency power supply (1) to the light in an emergency situation such as a fire, and a bell (9) connected to the fire contact (22) which generates a warning sound in case of fire.

[0042] Therefore, in normal times, the inspection remote control can be operated for fire drills to check whether the emergency exit light (4) is working properly, and in an emergency situation such as a fire, the fire detection sensor (10) causes the fire contact (22) of the control circuit to be automatically connected to the emergency power supply (1), thereby allowing the emergency exit light (4) to be turned on automatically.

[0043] For reference, the fire hydrant lights (5a, 5b) and the SVP lights (6) may be kept lit at all times. However, depending on the situation and location, the emergency exit lights (4), fire hydrant lights (5a, 5b), and SVP lights (6) may be switched on and off using the inspection remote control (3).

[0044] And, referring to FIG. 5a, the fire hydrant light (5a) is installed at a certain height higher than the vehicle so that it can be identified from a distance even when a vehicle is parked at the location of the fire hydrant.

[0045] Meanwhile, in the fire-time movement notification system according to one embodiment of the present invention, a separate movement indicator module may be additionally installed as shown in FIGS. 7 and 8 to provide faster and more reliable movement guidance.

[0046] Referring to FIGS. 7 and 8, the movement path indicator module (7) may include a light source (71) installed at a predetermined location in an indoor space where there is an emergency exit (E) and a fire hydrant (p), a reflector (76) that reflects the light from the light source (71) to illuminate the floor of the movement path leading to the emergency exit (E) or the fire hydrant (P), and a slit panel (74) that is installed at a predetermined point on the path of the light from the light source to the reflector (76) so that the light becomes an arrow shape leading to the emergency exit (E) or the fire hydrant (P), and has an arrow hole (742) formed therein, which is an arrow-shaped hole through which the light passes.

[0047] That is, the movement path indicator module (7) enables arrow lights to be illuminated on the floors of multiple points simultaneously with a single light source. In particular, to enable light to be generated at multiple points simultaneously with a single light source, the reflector (76), as shown in FIG. 7, is composed of two or more mirrors that can independently adjust their angles so that arrow-shaped lights are simultaneously illuminated on the floors of different movement paths facing at least one emergency exit (E), at least one fire hydrant (P), and SVP (P), as shown in FIG. 8. The slit panels (74) can be provided in multiple numbers so that one corresponds to the number of mirrors forming the reflector (76).

[0048] That is, as shown in FIG. 7, a single beam of light irradiated from a single light source is reflected by a plurality of slit panels each having arrow holes formed therein and a plurality of reflectors arranged at different angles, and dispersed to multiple locations, thereby making arrow markings on the floor at multiple points as shown in FIG. 8.

[0049] At this time, the light source (71) is equipped with a spectroscopic unit (72) that expands the emission angle of light irradiated from the light source (71) and a condensing unit (73) that reduces the emission angle of light passing through the spectroscopic unit (72), with the spectroscopic unit (72) and the condensing unit (73) each composed of a plurality of lenses, so that the emission angle of light irradiated from the light source can be adjusted according to the number of lenses added or removed.

[0050] Additionally, as shown in FIG. 7, a slit support frame (75) is installed to support the slit panel (74) so ​​that the slit panel (74) can be installed spaced apart from the light source (71), and the slit panel (74) can be connected to the slit support frame (75) by an angle adjustment connector (751) in the form of a spherical hinge as shown in FIG. 9 so that the installation direction and installation angle can be freely adjusted within a certain range.

[0051] Therefore, even in cases where the indoor structure is completely different, the same system of the present invention can adjust the angles of the reflector and the slit panel to accurately display the movement paths to the emergency exit and the fire hydrant, respectively, according to the changed environment.

[0052] In particular, as illustrated in FIG. 9, the slit panel (74) is in the form of a circular disc, and a rotating frame (753) is provided on the edge of the slit panel (74) to connect the slit panel (74) to an angle adjustment connector (751), and a rotating handle (743) may be provided at a predetermined position on one of the two sides of the slit panel (74) to rotate the slit panel (74) and freely adjust the direction of the arrow of the arrow hole (742).

[0053] The slit panels (74) are connected by angle adjustment connectors (751) in the shape of spherical hinges, so that each of the multiple slit panels (74) can be adjusted independently of each other. Although not illustrated in detail, with reference to FIG. 7, the reflector (76) is also connected by angle adjustment connectors (751) in the shape of a hemisphere similar to a ceiling or wall, so that the angles can be adjusted independently of each other. Therefore, light passing through the slit panels (74) is reflected by the reflector (76) and can be directed onto the floor at a desired point as shown in FIG. 8.

[0054] However, even if it is possible to reflect and shoot light that has passed through the slit panel (74) at a desired point, it may be difficult to make the direction of the arrow point toward the emergency exit (E), etc., as shown in FIG. 8, by adjusting the reflection angle alone.

[0055] To solve this problem, as shown in FIG. 9, the slit panel (74) is rotatably coupled to the rotating frame (753) and a rotating handle (743) for rotation is provided so that the direction of the arrow can be freely adjusted.

[0056] Meanwhile, in FIG. 8, the point where the arrow is projected onto the floor is a location close to the emergency exit (E), etc. However, if the arrow projected toward the emergency exit (E) is projected onto the floor at a point far from the emergency exit (E), etc., and it is not known whether the direction of movement indicated by the arrow is toward the emergency exit (E) or toward the fire hydrant (P) or SVP (S), then a situation may occur where a person who needs to find the fire hydrant immediately goes to the emergency exit, or is guided toward the fire hydrant when trying to escape through the emergency exit.

[0057] To prevent such problems, a color filter (741) may be attached to the slit panel (74) so ​​that when an arrow-shaped light is shone at a specific point as shown in FIG. 10, the light passing through the slit panel (74) can take on a specific color so that it can intuitively know what the arrow is pointing to. Thus, if the color of the arrow is green, it can be intuitively identified as an emergency exit (E), and if it is red or pink, it can be identified as a fire hydrant (P) or an SVP (S). This feature can be particularly useful when the room is filled with smoke from combustion during a fire.

[0058] The present invention described above is not limited by the aforementioned embodiments and attached drawings, and it will be obvious to those skilled in the art that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
