Description

Technology Field

[0001] The present invention relates to an evacuation guidance display device and a method for operating the device, and more specifically, to an evacuation guidance display device and a method for operating the device configured to determine whether entry into the stairwell is possible through a fire door and the direction of evacuation through the stairwell based on fire-related sensor data received from a fire detection sensor installed on the stairwell side, and to provide an evacuation guidance display according to the result of the determination. Background Technology

[0002] Generally, buildings are equipped with firefighting equipment, such as evacuation guidance lights, emergency lighting, and fire detectors, to guide occupants to safety in the event of a fire. These conventional evacuation guidance systems assist in the evacuation of occupants by detecting the occurrence of a fire or displaying evacuation routes in predetermined directions.

[0003] However, most conventional evacuation guidance systems are limited to static indicators that simply light up or flash depending on whether a fire has occurred, and thus have limitations in effectively resolving the complex decision-making problems faced by occupants in actual fire situations. In particular, in areas adjacent to fire doors, it is difficult for occupants to immediately determine whether it is safe to open the door and enter the stairwell, and even after entering the stairwell, it is difficult to receive clear guidance on which direction to evacuate—up to or down to.

[0004] As a result, in the event of a fire, occupants must decide for themselves whether to enter the fire door or experience confusion while unable to determine the direction of evacuation inside the stairwell; such delays or misjudgments can lead to increased evacuation time and reduced safety. This problem becomes even more severe, particularly in situations where smoke spreads or visibility is reduced.

[0005] Furthermore, conventional evacuation guidance systems fail to provide the ability to dynamically determine the feasibility of fire door entry or the direction of evacuation by considering the actual safety conditions of the stairwell; additionally, as individual systems operate independently, there are limitations in providing consistent evacuation guidance within the building. Consequently, there is a continuously being raised need for technology that can reduce the burden of judgment on occupants in fire situations and provide more reliable evacuation guidance based on the safety conditions of the stairwell.

[0010] The above control unit communicates with another evacuation guidance display device installed within the same building to receive information on the judgment status or stairwell safety status of the other evacuation guidance display device, and can control the evacuation guidance display by correcting it based on the received information.

[0011] The control unit above can selectively determine the evacuation direction based on the relative distance or path relationship with the location of the fire by using the installation location information of the evacuation guidance display device and the installation location information of the other evacuation guidance display device.

[0012] The above control unit can select an evacuation guidance display pattern corresponding to received fire-related sensor data based on pre-stored evacuation manual data, and control the display unit according to the selected display pattern.

[0013] The above control unit may be configured to re-determine whether entry into the stairwell through the fire door is possible by considering together the sensor data received from the fire detection sensor and the status information received from the other evacuation guidance display device.

[0014] In addition, a method for operating an evacuation guidance display device according to an embodiment of the present invention includes the steps of: a communication interface unit receiving fire-related sensor data from a fire detection sensor installed on the stairwell side; and a control unit determining whether entry into the stairwell is possible through a fire door and the direction of evacuation through the stairwell based on the sensor data received through the communication interface unit, and controlling the operation of a display unit to provide an evacuation guidance display according to the determination result.

Effects of the invention

[0019] According to the evacuation decision support system and evacuation guidance display device of an embodiment of the present invention, by providing the result of determining whether entry into the stairwell is possible through the fire door and the evacuation direction based on fire-related sensor data received from a fire detection sensor installed on the stairwell side through an evacuation guidance display device installed on the interior side of the fire door, the occupant can intuitively recognize whether to evacuate and the evacuation direction immediately in front of the fire door in the event of a fire.

[0020] In particular, the evacuation guidance display device according to an embodiment of the present invention is configured to be installed above a fire door or at a location adjacent to an existing evacuation guidance display, thereby enabling application without altering the structure of the existing building or performing large-scale wiring work. Accordingly, construction time and installation costs can be significantly reduced for both new and existing buildings, and on-site applicability is greatly improved.

[0021] In addition, the evacuation guidance display device according to an embodiment of the present invention is configured to perform a decision-making function at the individual device level without relying on a central control device or a separate server, thereby allowing other evacuation guidance display devices to operate independently even in situations where some facilities are damaged or communication is restricted due to a fire. This prevents the loss of functionality of the entire system caused by a single point of failure and improves the reliability of evacuation guidance.

[0022] In addition, the evacuation guidance display device according to an embodiment of the present invention communicates with other evacuation guidance display devices installed within the same building to share judgment status or stairwell safety status information, thereby ensuring that evacuation guidance provided at various locations within the building maintains consistency. Accordingly, it is possible to prevent conflicting evacuation guidance from being provided along the movement paths of occupants and to induce a more efficient evacuation flow.

[0023] Furthermore, the evacuation guidance display device according to an embodiment of the present invention can selectively provide a display pattern suitable for a fire situation based on pre-stored evacuation manual data, thereby enabling flexible evacuation guidance in response to various building structures and operating environments, and allowing the system to be easily operated by simply updating the manual data during maintenance.

[0030] Hereinafter, the concept of the present invention and embodiments according thereto will be described in detail with reference to the drawings.

[0031] FIG. 1 is a schematic diagram showing an evacuation decision support system according to one embodiment of the present invention, FIG. 2a is a diagram showing the evacuation decision support system illustrated in FIG. 1, and FIG. 2b is an example of installation showing the installation state of a fire detection device and an evacuation guidance display device illustrated in FIG. 1.

[0032] As illustrated in FIGS. 1 to 2b, a decision support system (90) according to an embodiment of the present invention may be configured to include a fire detection device (100) and an evacuation guidance display device (110).

[0033] A fire detection device (100) included in an evacuation decision support system (90) according to one embodiment of the present invention is installed on the stairwell side and configured to detect whether a fire has occurred in the stairwell or a dangerous condition inside the stairwell. Here, the fire detection device (100) is configured to provide basic information for determining the safety status of the stairwell space into which an occupant enters based on the fire door, and the evacuation guidance display device (110) according to an embodiment of the present invention generates sensor data necessary for determining whether the fire door is open and the evacuation direction.

[0034] Specifically, the fire detection device (100) may include a sensor capable of detecting at least one of smoke, heat, temperature change, gas concentration, or a combination thereof, and may be configured to detect dangerous situations such as fire or smoke inflow occurring inside the stairwell at an early stage. It is preferable that the fire detection device (100) be installed in a location where it can effectively detect fire situations in the stairwell, such as the ceiling of the stairwell or an area adjacent to a fire door.

[0035] The fire detection device (100) according to an embodiment of the present invention is not limited to a configuration that operates dependently on a conventional fire receiver or central control device, but can be configured to provide detected sensor data by communicating directly or indirectly with an evacuation guidance display device (110). Accordingly, in an embodiment of the present invention, fire-related information of the stairwell can be transmitted to the evacuation guidance display device (110) without requiring a separate central receiver or complex wiring work, thereby improving the convenience of installation and construction.

[0036] In addition, the fire detection device (100) may be linked to a fire detection facility already installed in an existing building, or implemented as a standalone detection device additionally installed according to an embodiment of the present invention. In this case, fire detection information on the stairwell side can be utilized in the evacuation decision support system (90) without the need to change the structure of the existing fire detection facility or perform additional large-scale construction. This configuration can be easily applied not only to new buildings but also to existing buildings, thereby satisfying the requirements for ease of installation and field applicability according to an embodiment of the present invention.

[0037] Meanwhile, the fire detection device (100) can transmit detected fire-related sensor data to the evacuation guidance display device (110) via wired or wireless communication methods, and the communication method used at this time can be implemented as a short-range communication method suitable for the environment inside the building. In this way, the fire detection device (100) performs the role of providing basic data necessary for the evacuation guidance display device (110) to determine whether entry into the stairwell through the fire door is possible and the evacuation direction by providing information indicating the safety status of the stairwell quickly and stably.

[0038] Accordingly, the fire detection device (100) according to the embodiment of the present invention is not limited to merely indicating whether a fire has occurred, but functions as a key information providing device to support decision-making regarding whether to open the fire door and the direction of evacuation, and enables the occupant to make a more reliable evacuation judgment in front of the fire door through combination with the evacuation guidance display device (110).

[0039] An evacuation guidance display device (110) included in an evacuation decision support system (90) according to one embodiment of the present invention is configured to be installed on the indoor side relative to the fire door, that is, in an area located before the occupant passes through the fire door. In particular, as shown in FIG. 2b, the evacuation guidance display device (110) is positioned on the upper side of the indoor side of the fire door or in a location adjacent to an existing evacuation guidance display, thereby allowing the occupant to intuitively recognize evacuation guidance information without any separate movement or additional verification action while approaching the fire door.

[0040] The evacuation guidance display device (110) according to an embodiment of the present invention performs the role of providing information to the occupant regarding whether it is safe to open the fire door and enter the stairwell, and the direction of evacuation through the stairwell, based on fire-related sensor data provided by a fire detection device (100) installed on the stairwell side. Accordingly, unlike conventional evacuation guidance displays that simply display the fixed location of stairs or emergency exits, the evacuation guidance display device (110) is configured to provide evacuation guidance information that reflects the safety status of the stairwell, which may vary depending on the situation of a fire.

[0041] Specifically, the evacuation guidance display device (110) supports immediate evacuation decision-making in front of the fire door by indicating whether the occupant may open the fire door and enter the stairwell depending on whether there is a fire or smoke entering the stairwell with the fire door in between. At this time, the evacuation guidance display device (110) can indicate whether entry into the fire door is possible through visual elements such as letters, symbols, colors, lighting or flashing patterns, and can be configured so that the occupant can easily recognize it even in a situation of smoke or confusion.

[0042] In addition, the evacuation guidance display device (110) can provide evacuation direction information regarding whether it is appropriate to move upward or downward along the stairs, only when evacuation through the stairwell is possible. Accordingly, the occupant can recognize information regarding the evacuation direction in advance at the stage before entering the fire door, without needing to make additional judgments inside the stairwell after passing through the fire door. This configuration contributes to minimizing the occupant's judgment delay in the event of a fire and reducing confusion during the evacuation process.

[0043] Meanwhile, the evacuation guidance display device (110) according to an embodiment of the present invention is not configured to replace existing emergency exit guide lights or stair location indicators, but rather to be installed adjacent to them and recognized together with the location information provided by existing evacuation guidance indicators. That is, while existing guide lights perform the role of indicating "the location where the stairs are located," the evacuation guidance display device (110) performs the role of supplementing the existing evacuation guidance system by providing judgment information regarding "whether it is safe to enter the stairs in the current fire situation and in which direction to evacuate."

[0044] Furthermore, by adopting a structure in which the evacuation guidance display device (110) is installed above the fire door, it can be applied not only to new buildings but also to existing buildings without large-scale structural changes or complex wiring work. This installation structure makes it easy to relocate or reinstall the evacuation guidance display device (110) together with the fire door when replacing or maintaining it, thereby improving the convenience of installation and maintenance.

[0045] Accordingly, the evacuation guidance display device (110) according to an embodiment of the present invention is configured to intuitively provide key information regarding the safety status of the stairwell and the evacuation direction at the location where the occupant's evacuation decision is actually made, centered around the fire door, thereby overcoming the limitations of conventional static evacuation guidance displays and supporting more reliable and efficient evacuation in the event of a fire.

[0046] To examine further, the evacuation guidance display device (110) included in the evacuation decision support system (90) according to one embodiment of the present invention is installed on the indoor side where the occupant is located relative to the fire door, and provides information so that the occupant can make a decision regarding evacuation before opening the fire door.

[0047] FIG. 2a is a diagram that schematically illustrates a simplified configuration of the evacuation decision support system shown in FIG. 1, clearly showing the conceptual relationship in which a fire detection device (100) installed on the stairwell side and an evacuation guidance display device (110) installed on the interior side of the fire door are positioned in correspondence with each other with the fire door in between. As shown in FIG. 2a, in an embodiment of the present invention, the fire detection device (100) performs the role of detecting whether fire or smoke has entered the stairwell, and the evacuation guidance display device (110) performs the role of providing information necessary for evacuation judgment to the occupant based on the detection result. By spatially separating the detection function and the guidance function in this way, the occupant can recognize the safety status of the stairwell in advance without directly entering the stairwell.

[0048] Meanwhile, FIG. 2b is a diagram illustrating an exemplary state in which a fire detection device (100) and an evacuation guidance display device (110) are installed in an actual building environment. As shown in FIG. 2b, the evacuation guidance display device (110) may be installed in the upper part of the interior side of the fire door, for example, in an area adjacent to where an existing stair guide light or emergency exit guide light is installed. This installation location is an area where occupants naturally look even in normal times, allowing occupants to immediately recognize the evacuation guidance display without separate searching in the event of a fire.

[0049] In particular, the evacuation guidance display device (110) according to an embodiment of the present invention is configured not to replace the "location information of stairs or emergency exits" provided by conventional guide lights, but to be recognized together with said location information. That is, while existing guide lights perform the role of indicating the existence of the stairs themselves, the evacuation guidance display device (110) reflects the safety status of the stairwell, which may vary depending on the fire situation, and provides judgment information regarding whether entry into the stairwell is possible through the fire door and the direction of evacuation via the stairs. Accordingly, the occupant can recognize the location of the stairs through the existing guide lights, and at the same time, judge whether it is appropriate to use the stairs in the current situation through the evacuation guidance display device (110).

[0050] In addition, as shown in FIG. 2b, the evacuation guidance display device (110) can be installed as an integrated or attached structure on the upper part of the fire door, so that it can be applied not only to new buildings but also to existing buildings already in use without separate structural changes or large-scale wiring work. This is intended to simplify the installation process and reduce construction costs according to the embodiment of the present invention, and to allow the device to be moved or reinstalled together when replacing or maintaining the fire door.

[0051] Accordingly, the evacuation guidance display device (110) according to an embodiment of the present invention is configured to directly support the evacuation decision that an occupant must actually make in front of a fire door through a spatial separation structure of detection and guidance as shown in FIG. 2a and an installation structure adjacent to the upper part of the fire door and existing guide lights as shown in FIG. 2b. This configuration provides "information on whether to enter the fire door" that conventional static evacuation guidance displays could not provide, thereby reducing confusion among occupants in the event of a fire and enabling safer and more efficient evacuation.

[0052] In addition to the above, the fire detection device (100) and evacuation guidance display device (110) of FIGS. 1 to 2b can perform various operations, and since the relevant details will continue to be covered later, the details will be replaced by those details.

[0053] FIG. 3 is a block diagram schematically showing the internal configuration of an evacuation guidance display device according to one embodiment of the present invention.

[0054] As illustrated in FIG. 3, the evacuation guidance display device (110) of FIG. 1 according to an embodiment of the present invention includes some or all of a communication interface unit (300), a display unit (310), a control unit (320), an evacuation decision support unit (330), a battery unit (340), and a storage unit (350).

[0055] Here, "including some or all" means that some components, such as the storage unit (350), may be omitted to form the evacuation guidance display device (110) of FIG. 1, or some components, such as the evacuation decision support unit (330), may be integrated into other components, such as the control unit (320), and is described as including all to aid in a sufficient understanding of the invention.

[0056] An evacuation guidance display device (110) according to one embodiment of the present invention includes a communication interface unit (300) for receiving fire-related sensor data from a fire detection device (100) installed on the stairwell side. The communication interface unit (300) receives information indicating the safety status of the stairwell from the outside when a fire occurs, and performs the role of providing basic data necessary for the evacuation guidance display device (110) to determine whether entry into the stairwell through the fire door is possible and the evacuation direction.

[0057] Specifically, the communication interface unit (300) may be configured to receive sensor data or fire status signals output from the fire detection device (100) via wired or wireless communication. At this time, the communication interface unit (300) may be configured to directly receive the detection results not only when the fire detection device (100) is installed in conjunction with a conventional central receiver, but also when the fire detection device (100) operates independently. Accordingly, in an embodiment of the present invention, fire-related information on the stairwell side can be transmitted to the evacuation guidance display device (110) without requiring a separate central receiver or control device as an essential component.

[0058] Additionally, the communication interface unit (300) may be configured to communicate with other evacuation guidance display devices installed within the same building to receive information regarding the judgment status or stairwell safety status of the other evacuation guidance display devices. For example, when status information such as "stairwell smoke detected" or "entry impossible determined" is received from an evacuation guidance display device installed near a specific floor or a specific stairwell, the communication interface unit (300) transmits the information to the control unit (320) so that the evacuation guidance display of the evacuation guidance display device (110) maintains consistency with the guidance display at other locations within the building.

[0059] At this time, the communication method supported by the communication interface unit (300) is based on a short-range communication method suitable for the internal environment of a building, and does not require satellite location-based communication or external network connection. For example, the communication interface unit (300) can be configured through a wireless communication method, a wired communication method, or a combination thereof that can be used inside a building, and can be configured so that communication with an adjacent device can be maintained even if some communication paths are blocked in the event of a fire.

[0060] In addition, the communication interface unit (300) can determine the validity of received sensor data or status information in consideration of situations where communication stability is degraded in the event of a fire, or support the control unit (320) in maintaining or switching the evacuation guidance display based on the last received status information even if reception is interrupted for a certain period of time. With this configuration, the basic guidance function of the evacuation guidance display device (110) can be maintained even if a temporary communication failure occurs in a fire situation.

[0061] Accordingly, the communication interface unit (300) according to the embodiment of the present invention is not merely a simple data receiving means, but functions as a core component that collects fire-related information from the fire detection device (100) on the stairwell side and other evacuation guidance display devices within the same building, and stably provides information necessary for the evacuation guidance display device (110) to support evacuation decision-making in front of the fire door.

[0062] An evacuation guidance display device (110) according to one embodiment of the present invention includes a display unit (310), and the display unit (310) is configured to provide visual information to directly support the evacuation decision that an occupant must actually make in front of a fire door when a fire occurs.

[0063] According to an embodiment of the present invention, conventional emergency exit guide lights or stair guidance indicators are limited to the function of guiding the location of stairs or emergency exits, and thus there was a problem in that it is difficult for occupants to determine whether to enter the stairs even when smoke or flames have entered the stairwell in the event of a fire. In particular, although fire doors are designed to block the spread of fire, occupants cannot verify the safety status inside the stairwell until they open the fire door; therefore, whether or not to open the fire door itself becomes a critical evacuation decision factor.

[0064] Accordingly, the display unit (310) according to the embodiment of the present invention is configured not only to display the location of the stairs like a conventional guide light, but to clearly indicate whether entry into the stairwell through the fire door is possible based on fire-related sensor data provided by a fire detection device installed on the stairwell side. That is, the display unit (310) directly provides the occupant with "whether entry into the relevant stairs is permitted in the current fire situation," rather than "where the stairs are."

[0065] In addition, according to an embodiment of the present invention, when a fire occurs, the first thing an occupant must determine in front of a fire door is whether entry into the stairwell is possible, and subsequently, the direction of evacuation via the stairs. Reflecting this, the display unit (310) may be configured to include a first display area indicating whether entry into the fire door is possible and a second display area indicating the direction of evacuation via the stairs. In this case, the first display area displays a state such as "entry possible" or "entry impossible" using characters, symbols, colors, lighting, or flashing patterns, and the second display area provides an arrow or direction indicator indicating which direction to move, either downward or upward, on the stairs.

[0066] Specifically, when no smoke or fire hazard is detected on the stairwell side, the display unit (310) may be configured to light up an indicator showing that entry through the fire door is possible, and when smoke or fire hazard is detected in the stairwell, it may be configured to flash an indicator showing that entry through the fire door is impossible or switch to another color. Through this display method, occupants can intuitively recognize whether entry through the stairwell is possible without having to read complex text.

[0067] In addition, the display unit (310) according to the embodiment of the present invention is configured to display information regarding whether the evacuation direction via the stairs is upward or downward, only when entry into the stairwell is possible. Thus, the occupant can recognize information regarding the evacuation direction in advance at the stage before the fire door without needing to make additional judgments inside the stairwell after passing through the fire door.

[0068] Meanwhile, the display unit (310) according to the embodiment of the present invention is not intended to replace existing emergency exit guide lights or stair location indicators, but is configured to be installed adjacent to them and recognized together. That is, the existing guide lights perform the role of guiding the location of stairs or emergency exits, and the display unit (310) performs the role of supplementing the conventional evacuation guidance system by providing judgment information regarding whether entering the location is appropriate in the current situation and the direction of evacuation.

[0069] In addition, the display unit (310) adopts a structure installed above the fire door, so that it can be applied not only to new buildings but also to existing buildings without separate structural changes or large-scale wiring work. This installation structure facilitates the relocation or reinstallation of the evacuation guidance display device including the display unit (310) when replacing or maintaining the fire door, thereby improving construction convenience and maintenance efficiency.

[0070] Furthermore, the display unit (310) may be configured to provide different display modes in normal times and in the event of a fire, taking into account environments where smoke, power outages, or poor visibility may occur. For example, in the event of a fire, only essential information such as whether entry through the fire door is possible and the evacuation direction may be emphasized and displayed, and unnecessary displays may be minimized to reduce the cognitive burden on the occupant.

[0071] Accordingly, the display unit (310) according to the embodiment of the present invention provides information regarding whether entry into the stairwell is possible and the direction of evacuation in stages at a key location for evacuation decision-making, which is in front of the fire door, thereby overcoming the limitations of conventional static evacuation guidance displays and enabling safer and more efficient evacuation in the event of a fire.

[0072] An evacuation guidance display device (110) according to one embodiment of the present invention includes a control unit (320), and the control unit (320) is a component that controls the overall operation of the evacuation guidance display device (110) and controls a display unit (310) so that an evacuation guidance display is provided based on fire-related information received through a communication interface unit (300).

[0073] The control unit (320) according to an embodiment of the present invention may be configured as a single chip, such as an integrated circuit (IC) chip, including a processor such as a central processing unit (CPU) and a memory such as RAM. In this case, the control unit (320) can substantially perform all functions performed by the evacuation decision support unit (330) by loading and executing a program mounted on the storage unit or the evacuation decision support unit (330) into memory.

[0074] However, to facilitate a sufficient understanding of the present invention, the control unit (320) is described in this specification as a component that performs the overall control operation of the evacuation guidance display device (110), and the evacuation decision support unit (330) is described as a functional component equipped with logic or a program that supports evacuation judgment. That is, the control unit (320) performs the role of comprehensively controlling the operation of the display unit (310), the communication interface unit (300), and the battery unit (340), including the operation of the evacuation decision support unit (330).

[0075] Specifically, the control unit (320) is configured to determine whether entry into the stairwell is possible through the fire door and the direction of evacuation through the stairwell based on the sensor data received from a fire detection device installed on the stairwell side through the communication interface unit (300). At this time, the control unit (320) determines whether the stairwell is in a safe state or a dangerous state by considering the type, value, or state change of the received sensor data, and controls the evacuation guidance display provided by the display unit (310) according to the result of the determination.

[0076] Additionally, the control unit (320) may be configured to correct or update the display content of the display unit (310) by taking into account status information or judgment results received from other evacuation guidance display devices installed within the same building. For example, if a dangerous condition is determined in an adjacent stairwell, the control unit (320) may refer to the relevant information to change the evacuation direction provided by the evacuation guidance display device (110) or to prioritize displaying a state where entry into the stairwell is impossible.

[0077] Meanwhile, the control unit (320) may be configured to maintain the evacuation guidance display or switch it in stages based on the latest sensor data received for a certain period of time or a judgment result, taking into account situations where communication is temporarily interrupted or the reception of some sensor data is restricted in the event of a fire. With such a configuration, the basic guidance function of the evacuation guidance display device (110) can be maintained even if a temporary communication failure occurs in a fire situation.

[0078] Additionally, the control unit (320) monitors the power status of the battery unit (340) and can control the evacuation guidance display device (110) to switch to emergency power and operate even when the commercial power is cut off. In this case, the control unit (320) switches the operation mode of the display unit (310) to prioritize displaying only essential evacuation information in a fire situation, thereby enabling the evacuation guidance function to continue even in a limited power environment.

[0079] Accordingly, the control unit (320) according to the embodiment of the present invention can not only operate as the execution entity of a program installed in the evacuation decision support unit (330), but also functions as a core component that comprehensively controls the overall operation of the evacuation guidance display device (110), and is configured to effectively support the evacuation decision that an occupant must make in front of a fire door.

[0080] An evacuation guidance display device (110) according to one embodiment of the present invention includes an evacuation decision support unit (330), and the evacuation decision support unit (330) is a functional component in which judgment logic, rules, or programs are implemented to support decision-making related to the evacuation of occupants in the event of a fire.

[0081] The evacuation decision support unit (330) according to an embodiment of the present invention is configured to support a determination regarding whether entry into the stairwell through the fire door is possible and the direction of evacuation through the stairwell by comprehensively considering fire-related sensor data received through the communication interface unit (300), status information received from other evacuation guidance display devices within the same building, and evacuation manual data or judgment rules stored in the storage unit (350).

[0082] Specifically, the evacuation decision support unit (330) may include criteria for determining the dangerous state of the stairwell based on smoke, heat, temperature changes, or a combination thereof detected on the stairwell side. For example, it may be configured to determine that evacuation through the stairwell is possible if smoke is not detected in the stairwell or is detected at a level below a threshold value, and to determine that entry into the stairwell is impossible if smoke or heat exceeds a threshold value.

[0083] Additionally, the evacuation decision support unit (330) may include criteria for determining the direction of evacuation via the stairs, only when entry into the stairwell is possible. At this time, the evacuation decision support unit (330) may be configured to determine which direction, upward or downward, is appropriate to move based on the location of the fire, the relationship between floors, the structure of the stairs, or evacuation manual data stored in the storage unit (350). Accordingly, the occupant may receive information regarding the direction of evacuation in advance before passing through the fire door.

[0084] Meanwhile, the evacuation decision support unit (330) according to an embodiment of the present invention may be configured to correct or update the reliability of the evacuation judgment by referring to judgment status or stairwell safety status information received from other evacuation guidance display devices installed within the same building. For example, if a dangerous state is determined by an evacuation guidance display device located in an adjacent stairwell or on an upper or lower floor, the evacuation decision support unit (330) may be configured to change the judgment result of the current device or set it conservatively by considering the relevant information.

[0085] Additionally, the evacuation decision support unit (330) may be configured to maintain or gradually switch judgments based on the recent judgment results stored in the storage unit (350), basic evacuation rules, or predefined safety priority rules, taking into account situations where communication is temporarily interrupted or the reception of sensor data is restricted in the event of a fire. Accordingly, even in situations where some information is missing, the evacuation guidance display device (110) can continuously provide at least a minimum evacuation judgment function.

[0086] The evacuation decision support unit (330) according to an embodiment of the present invention may be implemented in the form of a program executed by the control unit (320), and may be loaded into the memory of the control unit (320) and executed after being stored in the storage unit (350). In this case, the evacuation decision support unit (330) may not be physically separated as a separate hardware component, but may operate by being logically combined with the control unit (320). However, to aid in understanding the invention, the evacuation decision support unit (330) is described in the embodiment of the present invention as a functional component that supports evacuation judgment.

[0087] Accordingly, the evacuation decision support unit (330) according to the embodiment of the present invention does not merely function to transmit sensor data, but also performs the role of supporting the control unit (320) to provide a more reliable evacuation guidance display by providing a logical judgment system to support the key evacuation judgment that an occupant must make in front of a fire door in a fire situation.

[0088] An evacuation guidance display device (110) according to one embodiment of the present invention includes a battery unit (340), and the battery unit (340) is a component for supplying power so that the evacuation guidance display device (110) can operate normally even in the event of a fire or when the commercial power supply is cut off.

[0089] The battery unit (340) according to an embodiment of the present invention may include a rechargeable or non-rechargeable battery, and may be configured to be charged using the commercial power or maintained in a standby state when commercial power is normally supplied, and to automatically switch to an emergency power supply mode when the supply of commercial power is interrupted due to a power outage or fire. Such automatic switching operation may be monitored and controlled by a control unit (320).

[0090] The battery unit (340) may be designed to supply stable power for a certain period of time or longer so that the display unit (310), control unit (320), communication interface unit (300), and evacuation decision support unit (330) can perform minimum evacuation guidance functions even in a fire situation. For example, it may be configured to prioritize the supply of power necessary to display the evacuation direction and whether entry through the fire door is possible, which are essential information for occupants in the event of a fire.

[0091] In addition, the battery unit (340) according to an embodiment of the present invention may be configured to switch the operation mode of the evacuation guidance display device (110) under the control of the control unit (320) in order to minimize power consumption in a fire situation. For example, normally, the display unit (310) may be maintained in a standby state or a low-brightness display state, but when a fire occurs, it may be switched to provide only essential evacuation guidance displays in a high-brightness or flashing manner. By switching the operation mode in this way, the efficiency of using the power supplied by the battery unit (340) can be improved.

[0092] Meanwhile, the battery unit (340) may be placed inside a housing having a certain level of heat resistance, impact resistance, or smoke-proof structure, considering durability in a fire environment. Accordingly, even in situations where heat or external impact from a fire occurs, the battery unit (340) does not lose its function within a short period of time and supports the evacuation guidance display device (110) to perform the evacuation guidance function for the required time.

[0093] Additionally, the battery unit (340) may be configured to provide the remaining capacity, charging status, or abnormality status to the control unit (320), and the control unit (320) may be configured to monitor the status of the battery unit (340) by referring to the information or to store the status history in the storage unit (350). Through this, the timing for battery replacement or abnormality status can be identified in advance during the normal maintenance phase.

[0094] The battery unit (340) according to an embodiment of the present invention may be configured to be built into the evacuation guidance display device (110) itself, without relying on a central control device or an external power system. Accordingly, even in situations where the power supply to the entire building is cut off or some facilities are damaged due to fire, individual evacuation guidance display devices (110) can independently perform evacuation guidance functions.

[0095] Accordingly, the battery unit (340) according to the embodiment of the present invention is a key component that supports the continuous maintenance of the display and judgment functions of the evacuation guidance display device (110) even in the event of a fire or power outage, and plays a role in preventing the evacuation decision-making that an occupant must perform in front of a fire door from being interrupted.

[0096] An evacuation guidance display device (110) according to one embodiment of the present invention includes a storage unit (350), and the storage unit (350) is a component for storing various programs and data necessary for the operation of the evacuation guidance display device (110).

[0097] The storage unit (350) according to an embodiment of the present invention may be implemented as a non-volatile memory, such as a flash memory, EEPROM, or a similar storage medium, and may be configured to maintain the stored information even when the power to the evacuation guidance display device (110) is cut off. The storage unit (350) is accessed and managed by a control unit (320), and the control unit (320) controls the overall operation of the evacuation guidance display device (110) by loading the information stored in the storage unit (350) into memory to execute or refer to it.

[0098] Specifically, the storage unit (350) can store evacuation judgment programs, judgment rules, or logical data used by the evacuation decision support unit (330). For example, a reference value for determining whether entry into a stairwell is possible, a rule for determining the evacuation direction, and a safety priority rule applied preferentially in a fire situation may be stored in the storage unit (350), and the control unit (320) executes the functions of the evacuation decision support unit (330) by referring to such stored data.

[0099] Additionally, the storage unit (350) can store building-related data such as building structure information, stair location information, inter-floor relationship information, or evacuation route information. This information can be used by the evacuation decision support unit (330) to determine the evacuation direction or to correct the evacuation guidance display provided through the display unit (310).

[0100] Meanwhile, the storage unit (350) may be configured to store historical data indicating the operating status of the evacuation guidance display device (110) in the event of a fire or during normal times. For example, the time of reception of fire-related sensor data, the history of changes in judgment results, changes in the display status of the display unit (310), the communication status of the communication interface unit (300), or the remaining power status of the battery unit (340) may be recorded in the storage unit (350). Such historical data may be utilized in post-analysis, maintenance, or device inspection processes.

[0101] Additionally, the storage unit (350) can store the operation mode of the evacuation guidance display device (110), the display pattern setting of the display unit (310), the power saving setting, or user-defined setting information according to the control of the control unit (320). Accordingly, the operation of the evacuation guidance display device (110) can be flexibly set according to the installation environment of the device or the characteristics of the building.

[0102] The storage unit (350) according to an embodiment of the present invention may be configured to be updated through communication with an external device or another evacuation guidance display device within the same building. For example, if evacuation manual data or judgment rules stored in the storage unit (350) are changed, the control unit (320) may be configured to reflect the updated data received through the communication interface unit (300) in the storage unit (350). In this way, the evacuation guidance standards can be maintained in the latest state without changing the hardware of the device.

[0103] Additionally, the storage unit (350) may be configured to store basic evacuation rules or final safety rules in preparation for situations where communication is interrupted or the reception of some data is restricted in the event of a fire. Accordingly, the control unit (320) can continuously perform minimum evacuation judgments and displays based on the data stored in the storage unit (350) even in situations where external information is insufficient.

[0104] Accordingly, the storage unit (350) according to the embodiment of the present invention serves as a core data storage means that supports the execution of the judgment logic of the evacuation decision support unit (330) and the control unit (320), and performs the role of supporting the evacuation guidance display device (110) to operate reliably even in fire situations and power outage situations.

[0105] In addition to the above, the communication interface unit (300), display unit (310), control unit (320), evacuation decision support unit (330), battery unit (340), and storage unit (350) of FIG. 3 can perform various operations, and other details have been sufficiently explained above, so they will be replaced with those details.

[0106] Meanwhile, the communication interface unit (300), display unit (310), control unit (320), evacuation decision support unit (330), battery unit (340), and storage unit (350) of FIG. 3 according to an embodiment of the present invention are composed of hardware modules that are physically separated from each other, but each module may store software for performing the above operations internally and execute it. However, since the software is a set of software modules and each module can be formed as hardware, the configuration will not be specifically limited to software or hardware. For example, the storage unit (350) may be a storage or memory which is hardware. However, since it is also possible to store information in a software repository, the above content will not be specifically limited.

[0107] In addition, as another embodiment of the present invention, the control unit (320) may include a CPU and memory and may be formed as a single chip. The CPU includes a control circuit, an arithmetic logic unit (ALU), an instruction interpretation unit, and a registry, and the memory may include RAM. The control circuit may perform control operations, the arithmetic logic unit may perform operations on binary bit information, and the instruction interpretation unit may include an interpreter or a compiler to perform operations that convert high-level language into machine language and machine language into high-level language, and the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of operation of the evacuation guidance display device (110) of FIG. 1, the data computation processing speed can be rapidly increased by copying a program stored in the evacuation decision support unit (330), loading it into memory, i.e., RAM, and then executing it. In the case of a deep learning model, it may be loaded into GPU memory instead of RAM and executed by using the GPU to accelerate the execution speed.

[0108] FIG. 4 is a flowchart for explaining the driving method of the evacuation guidance display device shown in FIG. 1.

[0109] For convenience of explanation, referring to FIG. 4 together with FIG. 1, the evacuation guidance display device (110) of FIG. 1 according to an embodiment of the present invention receives fire-related sensor data from a fire detection sensor (100) installed on the stairwell side (S400).

[0110] Specifically, the evacuation guidance display device (110) is configured to receive sensor data indicating whether a fire has occurred from a fire detection sensor or fire detection device installed on the stairwell side through a communication interface unit (300). The fire-related sensor data may be information corresponding to at least one of smoke, heat, temperature change, gas concentration, or a combination thereof, and is used as basic information for determining the safety status inside the stairwell.

[0111] According to an embodiment of the present invention, the sensor data can be received via a wired or wireless communication method and can be configured so that the evacuation guidance display device (110) receives it directly without necessarily passing through a separate central receiver or control device. Accordingly, even in a situation where part of the central facility or communication infrastructure is damaged due to a fire, fire detection information on the stairwell side can be transmitted to the evacuation guidance display device (110).

[0112] Additionally, the evacuation guidance display device (110) can receive stairwell safety status information or judgment status information transmitted from other evacuation guidance display devices installed within the same building, and this information can also be processed as part of the fire-related sensor data received in step S400. In this case, the evacuation guidance display device (110) can comprehensively utilize information collected from multiple devices without relying on the detection result of a single sensor.

[0113] Meanwhile, in step S400 according to an embodiment of the present invention, considering situations where communication is temporarily interrupted or the reception of sensor data is restricted, recent received sensor data or basic state information stored in the storage unit (350) may be referenced together. For example, if new sensor data is not received for a certain period of time, the evacuation guidance display device (110) may perform a determination of the next step based on the previous sensor data or predefined basic state information stored in the storage unit (350).

[0114] Accordingly, in step S400, the evacuation guidance display device (110) reliably receives sensor data indicating whether a fire has occurred and the danger status on the stairwell side, thereby securing basic information for determining whether entry into the stairwell is possible through the fire door and the evacuation direction in the subsequent step (S410).

[0115] An evacuation guidance display device (110) according to one embodiment of the present invention determines whether entry into the stairwell is possible through the fire door and the direction of evacuation through the stairwell based on fire-related sensor data received in step S400, and controls the operation of the display unit (310) to provide an evacuation guidance display according to the result of the determination (S410).

[0116] Specifically, the control unit (320) of the evacuation guidance display device (110) transmits fire-related sensor data received through the communication interface unit (300) to the evacuation decision support unit (330), or determines the safety status of the stairwell by referring to the judgment rules and evacuation manual data stored in the storage unit (350). At this time, the control unit (320) can determine whether entry into the stairwell through the fire door is possible or dangerous by determining whether smoke, heat, or temperature changes detected inside the stairwell exceed a predefined standard value.

[0117] Additionally, the control unit (320) is configured to determine the evacuation direction through the stairwell only when it is determined that entry into the stairwell is possible. At this time, the determination of the evacuation direction may be performed based on the location of the fire, the relationship between floors, and building structure information or evacuation manual data stored in the storage unit (350), and may be configured to determine which direction, upward or downward, is safer to move.

[0118] Meanwhile, in step S410 according to an embodiment of the present invention, judgment status information or stairwell safety status information received from other evacuation guidance display devices installed within the same building may be considered together. For example, if a dangerous state is determined by an evacuation guidance display device located in an adjacent stairwell or on an upper or lower floor, the control unit (320) may be configured to refer to the relevant information to prioritize determining a state where entry into the fire door is impossible or to conservatively change the evacuation direction. Accordingly, a more reliable evacuation judgment is made by reflecting the judgment results of multiple devices, rather than relying on the judgment of a single sensor or a single device.

[0119] The control unit (320) controls the operation of the display unit (310) according to the above-mentioned judgment result to provide evacuation guidance displays to the occupants. For example, if entry into the stairwell is possible, the display unit (310) can be controlled to display the direction of evacuation via the stairs along with a display indicating the state of entry into the fire door, and if entry into the stairwell is impossible, to provide a display indicating the state of entry into the fire door.

[0120] Additionally, the control unit (320) may be configured to switch the display mode so that, considering the power status in a fire situation, when emergency power is supplied by the battery unit (340), the display unit (310) prioritizes displaying only essential evacuation guidance information. Accordingly, evacuation judgment information that occupants must be aware of can be reliably provided even in a limited power environment.

[0121] Meanwhile, the judgment result and display status performed in step S410 can be recorded in the storage unit (350), and can be used as historical data for subsequent maintenance, inspection, or post-analysis.

[0122] Accordingly, in step S410, the evacuation guidance display device (110) determines whether entry into the stairwell is possible and the evacuation direction based on the received fire-related sensor data at a key location for evacuation decision-making, which is in front of the fire door, and provides the result of the determination as an intuitive evacuation guidance display, thereby effectively supporting the safe evacuation of occupants in the event of a fire.

[0123] The evacuation guidance display device (110) according to an embodiment of the present invention is driven primarily by the steps S400 and S410 described above, but considering the diversity of fire situations and actual building environments, the following additional operations may be selectively performed.

[0124] For example, after the evacuation guidance display device (110) receives fire-related sensor data in step S400, it may compare the trend of change in the received sensor data over a certain period of time to verify the reliability of the sensor data, or refer to the safety status information of the stairwell received from other evacuation guidance display devices within the same building. Through this, judgment errors caused by momentary false detection or communication errors can be reduced.

[0125] Additionally, the evacuation guidance display device (110) may be configured not only to immediately change the display state of the display unit (310) according to the evacuation judgment result performed in step S410, but also to update the display content step by step according to the progress of the fire situation. For example, if the state of being able to enter the stairwell changes to a dangerous state, the display unit (310) may be controlled to disable the existing evacuation direction display and emphasize the state of being unable to enter the fire door.

[0126] Meanwhile, the evacuation guidance display device (110) may be configured to maintain stable operation even when the communication status or power status changes during a fire situation. For example, when the commercial power is cut off and emergency power is supplied by the battery unit (340), the control unit (320) may switch the operation mode so that the display unit (310) provides only essential evacuation guidance information, and such operation may be performed based on emergency operation rules stored in the storage unit (350).

[0127] Additionally, the evacuation guidance display device (110) may be configured to record information related to the evacuation judgment result, display status, or power status performed in step S410 in the storage unit (350). This recorded information can be utilized for maintenance, inspection, or post-analysis of evacuation operations after the fire ends, and can contribute to improving the reliability of the device and management efficiency.

[0128] In addition, the evacuation guidance display device (110) may be configured to restore the display unit (310) to a normal state based on received sensor data or reference information stored in the storage unit (350) when the fire situation ends or the dangerous state of the stairwell is released. Accordingly, the device can automatically return to a normal state without separate manual operation.

[0129] Accordingly, the driving method of the evacuation guidance display device according to an embodiment of the present invention is centered on the step (S400) of receiving fire-related sensor data from a fire detection sensor installed on the stairwell side, and the step (S410) of determining whether entry into the stairwell through a fire door is possible and the evacuation direction based on the received sensor data, and controlling the operation of the display unit to provide an evacuation guidance display according to the result of the determination.

[0130] According to the driving method of the present invention, evacuation judgment information necessary for occupants can be directly provided at a key location for evacuation decision-making, such as in front of a fire door, without relying on a central receiver or a separate control device, and stable evacuation guidance is possible even in emergency situations such as fire, power outage, or communication failure.

[0131] Accordingly, the evacuation guidance display device and the driving method according to the embodiment of the present invention overcome the limitations of conventional static evacuation guidance methods and can more effectively support the safe evacuation of occupants in actual fire situations.

[0132] In addition to the above, the evacuation guidance display device (110) of FIG. 1 can perform various operations, and other detailed information has been sufficiently explained above, so it will be replaced with that information.

[0133] FIG. 5 is a schematic diagram illustrating an evacuation decision support system according to another embodiment of the present invention.

[0134] As illustrated in FIG. 5, an evacuation decision support system (490) according to another embodiment of the present invention includes some or all of an evacuation guidance display device (500), a fire detection device (510), a communication network (520), a fire safety management device (530), and a third-party device (540).

[0135] Here, "including some or all" means that some components, such as a third-party device (540), may be omitted to form the evacuation decision support system (490) of FIG. 5, or that some or all components constituting the fire safety management device (530) may be integrated into a network device (e.g., wireless exchange device, gateway, etc.) constituting the communication network (520). To facilitate a sufficient understanding of the invention, it is described as including all components.

[0136] An evacuation decision support system (490) according to another embodiment of the present invention includes an evacuation guidance display device (500), and the evacuation guidance display device (500) is a device that provides information to support the evacuation decision of an occupant in the event of a fire, and is configured to perform substantially the same or similar functions as the evacuation guidance display device shown in FIGS. 1 to 4.

[0137] An evacuation guidance display device (500) according to another embodiment of the present invention is configured to determine whether entry into the stairwell is possible through a fire door and the direction of evacuation through the stairwell based on fire-related sensor data received from a fire detection device (510), and to provide an evacuation guidance display according to the result of the determination. At this time, the evacuation guidance display device (500) may be directly or indirectly connected to the fire detection device (510) through a communication network (520).

[0138] Additionally, according to another embodiment of the present invention, the evacuation guidance display device (500) may be configured to communicate with the fire safety management device (530) through a communication network (520). In this case, the fire safety management device (530) may be a device that collects and manages fire status, stairwell safety status, or evacuation-related management information for the entire building or multiple zones, and the evacuation guidance display device (500) may be configured to correct or update the evacuation guidance display by referring to the management information or judgment results transmitted from the fire safety management device (530).

[0139] For example, if the fire safety management device (530) determines a specific stairwell or a specific floor as a danger zone, the evacuation guidance display device (500) may be configured to receive the information and display a state where entry through the fire door is impossible or to prioritize displaying an alternative evacuation direction. Accordingly, in addition to the judgment performed by the individual evacuation guidance display device (500), the individual evacuation guidance display device (500) may provide evacuation guidance that reflects building-unit management information.

[0140] Meanwhile, an evacuation guidance display device (500) according to another embodiment of the present invention may be linked with a third-party device (540) through a communication network (520). The third-party device (540) may be a building management system, an emergency broadcasting system, an access control system, or an external safety management system, and the evacuation guidance display device (500) may complementarily control the evacuation guidance display by referring to additional information provided by these devices.

[0141] However, the evacuation guidance display device (500) according to another embodiment of the present invention does not necessarily operate by relying on the fire safety management device (530) or the third-party device (540), and may be configured to independently perform an evacuation guidance function based on sensor data received from the fire detection device (510) even in situations where communication with these devices is impossible. That is, the evacuation guidance display device (500) may be configured to selectively reflect information from an upper or external system only when communication is possible, while maintaining a distributed evacuation judgment structure.

[0142] Additionally, the evacuation guidance display device (500) may be configured to provide evacuation guidance based on integrated management when communication with the upper system is normal, depending on the status of the communication network (520), and to provide evacuation guidance autonomously based on a stored evacuation manual or basic judgment rules when communication is disconnected or some functions are limited.

[0143] Accordingly, the evacuation guidance display device (500) according to another embodiment of the present invention functions as an evacuation decision support device capable of flexibly responding to various building environments and fire situations by selectively combining an autonomous evacuation judgment function at the individual device level and an integrated management function linked with a building or external system.

[0144] An evacuation decision support system (490) according to another embodiment of the present invention includes a fire detection device (510), and the fire detection device (510) is a device that detects a fire or signs of fire occurring within a building and generates fire-related sensor data.

[0145] A fire detection device (510) according to another embodiment of the present invention may be installed in a stairwell, corridor, indoor space, or an area adjacent thereto, and may be configured to detect at least one of smoke, heat, temperature change, gas concentration, or a combination thereof at the installation location. Accordingly, the fire detection device (510) may provide basic information for determining not only whether a fire has occurred but also the safety status inside the stairwell.

[0146] The fire detection device (510) may be configured to generate detected fire-related information in the form of fire-related sensor data and transmit it to the evacuation guidance display device (500), the fire safety management device (530), or at least one of these through the communication network (520). At this time, the fire detection device (510) may be configured to transmit sensor data directly to the evacuation guidance display device (500) without necessarily passing through a separate central receiver or control device.

[0147] In addition, according to another embodiment of the present invention, the fire detection device (510) may be configured to periodically transmit detected sensor data or to transmit on an event basis only when the sensor value exceeds a predefined threshold value. With such a configuration, rapid transmission of information regarding a fire situation is possible while reducing communication traffic.

[0148] Meanwhile, the fire detection device (510) can be linked with the fire safety management device (530) through a communication network (520), and the fire safety management device (530) can manage and analyze the fire status of the entire building or a specific area by integrating sensor data collected from multiple fire detection devices (510). In this case, the fire detection device (510) functions as a means of providing data for determining the fire status at the building level, going beyond being a simple detection device.

[0149] In addition, a fire detection device (510) according to another embodiment of the present invention may be configured to include its own power or emergency power in consideration of a situation where the power supply is interrupted, and may be configured to maintain at least minimal fire detection and sensor data transmission functions even in such cases.

[0150] However, the fire detection device (510) does not necessarily rely on the fire safety management device (530) or the third-party device (540) for operation, and even in situations where communication with these devices is impossible, it directly transmits fire-related sensor data to the evacuation guidance display device (500) to support the evacuation guidance display device (500) in independently performing evacuation judgment and evacuation guidance display.

[0151] Accordingly, the fire detection device (510) according to another embodiment of the present invention detects the safety status of the stairwell and indoor space in real time when a fire occurs, and provides the detection result to the evacuation guidance display device (500) and related system components, thereby functioning as a key information providing device to support the evacuation decision-making of occupants.

[0152] An evacuation decision support system (490) according to another embodiment of the present invention includes a communication network (520), and the communication network (520) provides a network environment that connects data to be transmitted and received between an evacuation guidance display device (500), a fire detection device (510), a fire safety management device (530), and a third-party device (540).

[0153] A communication network (520) according to another embodiment of the present invention may be composed of a wired communication network, a wireless communication network, or a combination thereof. For example, the communication network (520) may include at least one wired communication method such as Ethernet, serial communication, or power line communication (PLC), or a wireless communication method such as Wi-Fi, Bluetooth, Zigbee, LoRa, LTE / 5G, and may be appropriately selected according to the building environment, installation conditions, or communication stability requirements.

[0154] The communication network (520) may be configured to include network devices installed inside the building, such as a wireless exchange device, a gateway, or a relay device, and these network devices may be configured to collect data transmitted from a fire detection device (510) or an evacuation guidance display device (500) and transmit it to other components. In this case, the network devices function as part of the communication network (520).

[0155] According to another embodiment of the present invention, the communication network (520) does not necessarily have to include a central receiver or a control server, and can support a distributed communication structure in which the fire detection device (510) and the evacuation guidance display device (500) directly transmit and receive data through the communication network (520). Accordingly, even in a situation where some network facilities or the central device are damaged due to a fire, evacuation-related information can be transmitted through a minimal communication path.

[0156] Additionally, when the evacuation guidance display device (500) is linked with the fire safety management device (530), the communication network (520) can support the transmission of sensor data collected from multiple fire detection devices (510), stairwell safety status information, or evacuation judgment results to the fire safety management device (530). Along with this, management information or evacuation-related control information generated by the fire safety management device (530) can be transmitted back to the evacuation guidance display device (500) through the communication network (520).

[0157] Meanwhile, the communication network (520) may be configured to support linkage with a third-party device (540). For example, the communication network (520) may be linked with a building management system, an emergency broadcasting system, or an access control system so that the evacuation guidance display device (500) receives additional information provided by these devices or transmits evacuation judgment results to an external system.

[0158] A communication network (520) according to another embodiment of the present invention may be configured to selectively use at least one of a plurality of communication paths or communication methods, taking into account the possibility of communication failure occurring in a fire situation. For example, it may be configured to use wired communication normally, but switch to wireless communication when wired communication is interrupted, or to transmit data through an auxiliary communication path when the main communication path fails.

[0159] Additionally, the communication network (520) may be configured to set different transmission priorities according to the importance of the data being transmitted. For example, data related to whether a fire has occurred or whether entry to the stairwell is possible may be transmitted first, and additional data such as management or log information may be transmitted later.

[0160] However, the communication network (520) according to another embodiment of the present invention is not limited to being an essential component for the operation of the evacuation guidance display device (500), and even in situations where communication through the communication network (520) is temporarily impossible, the evacuation guidance display device (500) may be configured to autonomously perform an evacuation guidance function based on sensor data directly received from the fire detection device (510) or a stored evacuation manual.

[0161] Accordingly, the communication network (520) according to another embodiment of the present invention functions as a core infrastructure of an evacuation decision support system that can flexibly respond to various fire situations and building environments by selectively supporting interoperability with a building unit or an external system while based on distributed communication between individual devices.

[0162] An evacuation decision support system (490) according to another embodiment of the present invention includes a fire safety management device (530), and the fire safety management device (530) is a device for comprehensively managing fire occurrence situations and evacuation status within a building.

[0163] A fire safety management device (530) according to another embodiment of the present invention may be configured to receive fire-related sensor data, stairwell safety status information, evacuation judgment results, or device status information from a plurality of fire detection devices (510) and evacuation guidance display devices (500) through a communication network (520). Based on the received information, the fire safety management device (530) may determine the fire progression status and evacuation possibility status of the entire building or a specific area.

[0164] The fire safety management device (530) may be configured to store and manage received sensor data and judgment information, and to visualize or provide this information to a manager. For example, the fire safety management device (530) may support a manager in intuitively understanding the current safety status of the building by providing fire status, evacuation availability, or device operation status by floor or stairwell through a screen.

[0165] Additionally, a fire safety management device (530) according to another embodiment of the present invention may be configured to generate building-unit evacuation management information by synthesizing sensor data collected from a plurality of fire detection devices (510) or evacuation judgment results performed by a plurality of evacuation guidance display devices (500). In this case, the fire safety management device (530) may be configured to determine a specific stairwell or a specific area as a danger zone and to transmit the judgment result to the evacuation guidance display device (500) through a communication network (520).

[0166] Meanwhile, the fire safety management device (530) is not an essential component for replacing the autonomous evacuation judgment of the evacuation guidance display device (500), and is configured to selectively intervene only when communication is possible, while having a basic structure in which the evacuation guidance display device (500) independently performs the evacuation guidance function. That is, the fire safety management device (530) functions as a higher-level management device that complements the distributed evacuation judgment structure.

[0167] In addition, a fire safety management device (530) according to another embodiment of the present invention may be configured to perform limited management functions using only information within a receivable range, even if communication failure occurs or some devices are damaged in a fire situation. With such a configuration, the fire safety management device (530) can improve system resilience and management reliability in a fire situation.

[0168] The fire safety management device (530) may be linked with a fire facility management system, a building management system, or an external safety management system, and may be configured to transmit evacuation-related information to an external agency or management system. In this case, the fire safety management device (530) may function as a relay device or interface device for linkage with a third-party device (540).

[0169] However, the fire safety management device (530) according to another embodiment of the present invention is not limited to a device that performs forced control over the evacuation guidance display device (500), and the evacuation guidance display device (500) may be configured to correct or update the evacuation guidance display by utilizing information received from the fire safety management device (530) as reference information.

[0170] Accordingly, the fire safety management device (530) according to another embodiment of the present invention provides a structure that integrates and manages fire and evacuation information at the building level while maintaining the autonomous evacuation judgment function of the individual evacuation guidance display device (500), thereby performing the role of simultaneously improving evacuation management efficiency and system stability in a fire situation.

[0171] An evacuation decision support system (490) according to another embodiment of the present invention may further include a third-party device (540), wherein the third-party device (540) is a device or system existing outside the evacuation decision support system (490) and is a device that provides additional information related to a fire situation or evacuation or utilizes evacuation guidance results.

[0172] A third-party device (540) according to another embodiment of the present invention may be configured to communicate with a fire safety management device (530) or an evacuation guidance display device (500) through a communication network (520). In this case, the third-party device (540) is not an essential component of the present invention and may be selectively linked according to the building's management environment, operation policy, or system expansion requirements.

[0173] The third-party device (540) may be, for example, at least one of a building management system (BMS), an emergency broadcasting system, an access control system, an elevator control system, an external safety management server, or a cloud-based management system. This third-party device (540) may provide additional information related to evacuation in the event of a fire, or perform additional safety measures by utilizing the evacuation judgment results generated by the evacuation decision support system (490).

[0174] Specifically, the third-party device (540) may be configured to receive information regarding the safety status of the stairwell, evacuation availability, or evacuation direction transmitted from the fire safety management device (530) or the evacuation guidance display device (500), and to provide voice guidance to occupants through an emergency broadcast, or to control the access control system to restrict access to a specific area. Additionally, if linked with the elevator control system, control may be performed to restrict the operation of the elevator or move it to a specific floor in the event of a fire.

[0175] Meanwhile, the third-party device (540) may provide information provided from an external system to the evacuation decision support system (490). For example, an external safety management server or cloud system may provide past fire incidents, evacuation manual update information, or building operation policy information, and this information may be transmitted to the evacuation guidance display device (500) through the fire safety management device (530) and used to assist in evacuation guidance judgment.

[0176] However, the third-party device (540) according to another embodiment of the present invention is not a component that replaces or enforces the autonomous evacuation judgment function of the evacuation guidance display device (500), and the evacuation guidance display device (500) is configured to independently perform an evacuation guidance function based on sensor data received from the fire detection device (510) or a stored evacuation manual even in situations where communication with the third-party device (540) is impossible.

[0177] Additionally, interoperability with a third-party device (540) may be restricted in the event of a fire due to reasons such as communication failure, power cutoff, or system damage, and is configured so as not to affect the basic operation of the evacuation decision support system (490) even in such cases. That is, the third-party device (540) performs the role of expanding or supplementing the evacuation guidance function only when communication is possible, without compromising the stability of the system.

[0178] Accordingly, a third-party device (540) according to another embodiment of the present invention is optionally linked to an evacuation decision support system (490) and functions as an auxiliary component that expands the scope of utilization of evacuation guidance information and improves the safety management efficiency of the entire building.

[0179] In addition to the above, the contents related to the evacuation guidance display device (500), fire detection device (510), communication network (520), fire safety management device (530) and third-party device (540) of FIG. 5 have been sufficiently explained above, so we will substitute them with those contents.

[0180] Meanwhile, although it has been described that all components constituting an embodiment of the present invention are combined or operate in combination, the present invention is not necessarily limited to such an embodiment. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate. Furthermore, while all components may each be implemented as a single independent piece of hardware, they may also be implemented as a computer program having a program module that performs some or all of the combined functions on one or more pieces of hardware by selectively combining some or all of the components. The codes and code segments constituting the computer program can be easily inferred by those skilled in the art of the present invention. An embodiment of the present invention may be implemented by storing such a computer program on a non-transitory computer-readable medium, reading it, and executing it by a computer.

[0181] Here, a non-transient readable recording medium refers to a medium that stores data semi-permanently and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, the programs described above may be stored and provided on non-transient readable recording media such as CDs, DVDs, hard disks, Blu-ray discs, USBs, memory cards, and ROMs.
