Description

Information display type guidance light

The present invention relates to an information display type guidance light, and more specifically, to an information display type guidance light according to smart risk recognition.

Emergency lights or evacuation lights are lighting devices used in emergency situations on roads or buildings. In an emergency, facilities such as electricity or gas may fail, so emergency lights play an important role. They are usually green, red, or yellow, and the same colors as traffic lights are used. Yellow emergency lights serve to warn, red emergency lights serve to indicate danger, and green emergency lights serve to indicate a safe state. They should be actively used in emergencies, and facilities should be inspected regularly to ensure that they are functioning properly.

Here, the physical limitations of humans occur when a disaster occurs. When humans face an emergency situation when a disaster occurs, the survival and defense instincts of the cortex are activated first, which interferes with the function of the neocortex, resulting in a state of panic where rational judgment is impossible. In a state of excessive tension and extreme excitement, movements are very fast, but the brain's judgment is slow and flexible judgment of the situation is impossible. In the Daegu subway fire, people were aware that a fire had broken out, but they maintained a normal mentality that they would be safe, and only after the station announcement was made did they recognize the danger, leading to a panic phenomenon where the brain's consciousness level immediately moved from level 2 to level 4, resulting in the obstruction of safe evacuation.

Panic, which is the instinctive activity of the human brain when faced with danger, can be an important factor in preventing safe escape and putting people in dangerous situations.

In the event of a disaster, initial response within the golden time is very important to maximize survival rates.

Most studies conducted domestically and internationally emphasize the importance of initial response within the so-called golden time to minimize casualties in crowded facilities. A representative research case, presented at the conference on Fire Safety and Emergency in May 2014, described the negative impact on survival as time passes after a disaster, and revealed that emergency evacuation should be conducted in the initial stage to maximize the survival rate. After a disaster safety accident occurs, the initial response stage (Incipient Stage) passes and the growth and full development stage occurs, and the threat of damage increases rapidly.

The need for smart guidance lights due to disasters such as fires in densely populated facilities has been highlighted. According to the National Fire Agency, in 2020, a total of 38,659 fires occurred, resulting in 364 deaths and 1,915 injuries. The number of deaths increased by 27.7% (79 people) from the previous year, and a series of fire accidents occurred in densely populated facilities, such as the Donghae pension fire (January), the Icheon warehouse fire (April), and the Gunpo apartment fire (December).

In the case of the Gunpo apartment fire that occurred in December 2020, some of the deceased residents went to the elevator machine room, which was higher up, because they could not find the rooftop exit while trying to escape the fire, and the damage was expanded as they suffocated from the smoke.

Like this, large-scale disasters due to large-scale fire accidents are occurring one after another, and the scale of damage is increasing significantly as facilities become more complex and larger. It is urgent to establish a plan to conduct regular fire drills for residents and provide guidance on evacuation routes in case of fire so that they can respond quickly in an emergency.

In addition, evacuation guidance lights are installed in proportion to the type and size of the space rather than the detailed characteristics of the spatial structure, and are installed according to the general standards using fixed display surfaces. In addition, in the case of evacuation guidance by warning sounds that are repeated the same regardless of location or by a uniform public announcement, it is impossible to know where the disaster occurred or where to evacuate from the current location, so dynamic guidance reflecting the disaster location is impossible. As an evacuation facility, guidance lights cannot perform their intended role in an emergency if visibility is reduced due to obstruction of the field of vision by smoke from a fire, etc., or if the guidance lights are left in a turned off state due to negligence of management by a fire safety manager.

These emergency lights or evacuation guidance lights do not provide information on safe and quick evacuation routes to avoid a fire in the event of a fire, making it difficult to evacuate efficiently and safely.

Accordingly, the purpose of the present invention is to provide a smart risk recognition-based information display-type evacuation light that can detect a fire outbreak and inform evacuees of a safe evacuation route.

In order to achieve the above object, the present invention provides an information display type guidance light according to smart risk recognition, including a communication unit for communicating with the outside, a housing having an internal accommodation space, an emergency light unit supported by the housing and guiding an emergency exit for evacuation, an information display unit detachably coupled to the housing and providing at least one of a fire location, evacuation direction information, and evacuation possibility information, a power supply unit for supplying power, and an evacuation guidance control unit for controlling power to be constantly supplied to the emergency light unit, and for controlling the information display unit to provide at least one of a fire location, evacuation direction information, and evacuation possibility information based on the location of the risk when a risk occurs in a building. When a risk such as a fire occurs in the building, evacuation direction information and evacuation possibility information are provided to evacuees, so that evacuees can safely evacuate by looking at this information, so that safety against risk can be improved.

Here, it is preferable that the emergency light unit includes an emergency exit sign; a light output unit that outputs light toward the emergency exit sign; and a diffusion plate that allows light from the light output unit to be diffused to the entire area of the emergency exit sign, so that evacuees can accurately identify the emergency light unit.

And the above information display type guidance light further includes a light detection sensor that is placed in the housing and detects illuminance, and the evacuation guidance control unit stores the normal illuminance range in the housing, determines whether the illuminance detected by the light detection sensor is out of the normal illuminance range, and if the illuminance detected by the light detection sensor is determined to be out of the normal illuminance range, controls the communication unit to transmit a defect in the light output unit to the central management office, so that it is possible to immediately determine whether the lighting of the light output unit has reached the end of its life or is broken, so that the lighting of the light output unit can be repaired or replaced to safely prepare for danger, which is preferable.

Here, the information display type induction light further includes a current detection sensor that is disposed between the power supply unit and the emergency light unit and detects the current intensity moving to the emergency light unit, and the evacuation guidance control unit stores the normal current range supplied to the emergency light unit, and if it is determined that the illuminance detected by the illuminance detection sensor is outside the normal illuminance range, it determines whether the current intensity detected by the current detection sensor is outside the normal current range, and if it is determined that the current intensity detected by the current detection sensor is outside the normal current range, it controls the communication unit to transmit a defect in the power supply unit to the central management office, so that it is possible to immediately determine whether the power supply unit has reached the end of its life or has broken down, so that the power supply unit can be repaired or replaced to safely prepare for danger, which is preferable.

And the above information display unit is composed of a plurality of LEDs that can display text and images, and the evacuation guidance control unit controls the information display unit to provide information on the fire location, evacuation direction, and evacuation availability, so that the evacuation personnel are provided with text information about the fire location, evacuation direction, and evacuation availability, which is desirable because accurate information about evacuation can be delivered.

According to the present invention, when a danger such as a fire occurs in a building, the location of the fire, information on the direction of evacuation, and information on whether evacuation is possible are provided to evacuees, so that evacuees can safely evacuate by looking at this information, thereby improving safety against danger.

In addition, since evacuees can accurately check the emergency lighting unit and immediately determine whether the lighting in the light output section has reached the end of its life or is broken, it is effective in safely preparing for danger by repairing or replacing the lighting in the light output section.

In addition, since it is possible to immediately determine whether the power supply unit has reached the end of its life or is broken, it is possible to safely prepare for danger by repairing or replacing the power supply unit, and it is possible to accurately convey information about evacuation by providing text messages to evacuees about the location of the fire, information about the direction of evacuation, and information about whether evacuation is possible.

The emergency light unit (13) is supported on the housing (12) and guides the emergency exit for evacuation. The emergency light unit (13) includes an emergency exit sign (131), a light output unit (132), and a diffuser plate (133).

An emergency exit sign (131) can guide people to an exit for evacuation in the event of an emergency.

The light output unit (132) can output light toward the emergency exit sign (131).

The diffusion plate (133) can allow the light from the light output unit (132) to be diffused to the entire area of the emergency exit sign (131).

The information display unit (14) is detachably connected to the housing (12) and provides at least one of fire location information, evacuation direction information, and evacuation possibility information. The information display unit (14) includes an LED (141).

The LED (141) can be formed in multiple forms to enable displaying characters and images.

The power supply unit (15) supplies power. The power supply unit (15) may be configured as an SMPS that supplies external power to the inside, and in case power is not supplied from the outside, a battery may be additionally provided so that power is supplied from the battery when power is not supplied from the outside.

The light detection sensor (16) is placed inside the housing (12) and can detect light.

The current detection sensor (17) is placed between the power supply unit (15) and the emergency light unit (13) and can detect the current intensity flowing to the emergency light unit (13).

The evacuation guidance control unit (18) controls power to be supplied to the emergency light unit (13) at all times, and when a danger occurs within the building, controls the information display unit (14) to provide at least one of evacuation direction information and evacuation possibility information based on the location of the danger.

The evacuation guidance control unit (18) stores the normal illuminance range within the housing (12), determines whether the illuminance detected by the illuminance detection sensor (16) is outside the normal illuminance range, and if it is determined that the illuminance detected by the illuminance detection sensor (16) is outside the normal illuminance range, it can control the communication unit (11) to transmit a fault in the light output unit (132) to the central management office.

The evacuation guidance control unit (18) stores the normal current range supplied to the emergency light unit (13), and if it is determined that the illuminance detected by the illuminance detection sensor (16) is outside the normal illuminance range, it determines whether the current intensity detected by the current detection sensor (17) is outside the normal current range, and if it is determined that the current intensity detected by the current detection sensor (17) is outside the normal current range, it can control the communication unit (11) to transmit a fault in the power supply unit (15) to the central management office.

The evacuation guidance control unit (18) can control the information display unit (14) to provide information on the location of danger and whether entry is possible.

The server (20) includes a server communication unit (21), a risk detection unit (22), and a server control unit (23).

The server communication unit (21) can communicate with the communication unit (11). The server communication unit (21) can perform wireless communication, and the wireless communication includes at least one of infrared communication, RF, Zigbee, and Bluetooth. The server communication unit (21) receives a video signal and transmits it to the server control unit (23) described below, and can be implemented in various ways in response to the standard of the video signal to be received and the implementation form of the user terminal. For example, the server communication unit (21) can wirelessly receive an RF (radio frequency) signal transmitted from a broadcasting station (not shown), or can wiredly receive a video signal according to a composite video, component video, super video, SCART, HDMI (high definition multimedia interface) standard, etc. When the video signal is a broadcast signal, the server communication unit (21) can include a tuner that tunes the broadcast signal by channel.

The danger detection unit (22) can detect dangers within a building. The danger detection unit (22) includes a smoke sensor (221), a heat detection sensor (222), a flame detection sensor (223), a camera (224), a vibration detection sensor (225), a moisture detection sensor (226), and a pressure detection sensor (227). The danger detection unit receives detection signals from legal fire equipment (fire detectors, transmitters, etc.) within the building through a legal fire equipment (fire receiver) and transmits the corresponding information to a server to be used as input information for calculating an evacuation route.

The smoke sensor (221) detects smoke inside the building and may be composed of multiple sensors.

The heat detection sensor (222) may be composed of multiple sensors that detect heat inside a building.

The flame detection sensor (223) may be configured in multiple ways to detect flames within a building.

The cameras (224) may be configured in multiple configurations to photograph multiple areas within the building.

The vibration detection sensor (225) may be composed of multiple sensors that detect vibrations within the building.

The moisture detection sensor (226) may be composed of multiple sensors that detect humidity, water level, water leaks, etc. inside the building.

The pressure detection sensor (227) may be configured in multiple ways to measure the size of the pressure inside the building.

The server control unit (23) can create a safe evacuation route based on at least one risk area detected by the risk detection unit (22).

The server control unit (23) stores normal value ranges for smoke, heat, flame, vibration, moisture, and pressure, and can determine that a disaster including a fire has occurred when a detection signal detected by a smoke sensor (221), a heat detection sensor (222), a flame detection sensor (223), a camera (224), a vibration detection sensor (225), a moisture detection sensor (226), and a pressure detection sensor (227) exceeds the normal value range. In addition, the server control unit (23) stores multiple risks of disasters, and can determine the determined disaster as a fire based on the values of the corresponding sensors.

Here, the server control unit (23) can exclude areas judged to have a lot of moisture from the evacuation route when a fire occurs by considering the moisture detection sensor (226) in the area judged to have a lot of moisture. This is because there may be concerns about electric leakage, etc.

In addition, the server control unit (23) stores the normal vibration range and, if the vibration detected by the vibration detection sensor (225) exceeds the normal vibration range, the area of the vibration detection sensor (225) can be excluded from the evacuation route. This is because it is safe to set the evacuation route by avoiding areas of the building where there is a lot of shaking.

And the server control unit (23) stores the normal pressure range, and if the pressure detected by the pressure vibration detection sensor (227) exceeds the normal pressure range, the area of the pressure detection sensor (227) can be excluded from the evacuation route. The pressure in a certain area within the building may rise due to water or fire, and since this area is an area that is difficult to evacuate to, the evacuation route can be set by excluding this area.

The dispatch terminal (30) includes a dispatch communication unit (31), a dispatch display unit (32), a dispatch input unit (33), a dispatch speaker (34), a dispatch microphone (35), a dispatch camera (36), and a dispatch control unit (37).

The dispatch communication unit (31) can communicate with the outside so that a rescue request can be quickly sent when rescue or dispatch is required in an emergency situation. The dispatch communication unit (31) can perform wireless communication, and the wireless communication includes at least one of infrared communication, RF, Zigbee, and Bluetooth. The dispatch communication unit (31) receives a video signal and transmits it to the dispatch control unit (37) described below, and can be implemented in various ways in response to the standard of the received video signal and the implementation form of the user terminal. For example, the dispatch communication unit (31) can wirelessly receive an RF (radio frequency) signal transmitted from a broadcasting station (not shown), or can receive a video signal according to a composite video, component video, super video, SCART, HDMI (high definition multimedia interface) standard, etc. by wire. If the video signal is a broadcast signal, the dispatch communication unit (31) can include a tuner that tunes the broadcast signal by channel.

The dispatch display unit (32) can provide information necessary for evacuation and rescue in an emergency situation. The dispatch display unit (32) displays an image based on an image signal processed by image processing. The implementation method of the dispatch display unit (32) is not limited, and can be implemented in various display methods such as, for example, a liquid crystal, a plasma, a light-emitting diode, an organic light-emitting diode, a surface conduction electron-emitter, a carbon nano-tube, a nano-crystal, etc.

The dispatch display unit (32) may additionally include additional components depending on its implementation method. For example, if the dispatch display unit (32) is a liquid crystal display, the dispatch display unit (32) includes a liquid crystal display panel (not shown), a backlight unit (not shown) that supplies light thereto, and a panel driving board (not shown) that drives the panel (not shown). The dispatch display unit (32) may display a voice recognition result as information on the recognized voice. Here, the voice recognition result may be displayed in various forms such as text, graphics, and icons, and the text may include letters and numbers. The dispatch display unit (32) may further display candidate commands and application information according to the voice recognition result. The user may check whether the voice has been recognized correctly by the voice recognition result displayed on the dispatch display unit (32), and may select a command corresponding to the voice spoken by the user from among the displayed candidate commands by operating the dispatch input unit (33) provided on the remote control, or may select and check information related to the voice recognition result.

The dispatch input unit (33) can input information required for dispatch in an emergency situation. The dispatch input unit (33) can be formed by an input means through which a user can input a user command. The dispatch input unit (33) can receive a user's touch input or a user's remote input using a remote controller and transmit it to the corresponding dispatch control unit (37). In addition, the dispatch input unit (33) can receive a voice input spoken by the user and transmit the voice signal to the dispatch control unit (37). In that case, the dispatch input unit (33) can be implemented by, for example, a microphone. The dispatch input unit (33) can also perform signal processing on the received voice signal on its own. However, the form of the user input that the dispatch input unit (33) can receive is not limited thereto, and for example, user input through motion recognition, etc. can also be received.

The dispatch speaker (34) can output all audio including the audio of the video, the audio of the application, and the audio of the user in an emergency situation.

The dispatch microphone (35) can receive all audio including the audio of the video, the audio of the application, and the audio of the user in an emergency situation.

The emergency camera (36) can film the inside, outside and front of a building in an emergency situation.

The dispatch control unit (37) can control the dispatch communication unit (31) so that a rescue request can be sent quickly in an emergency situation when rescue or dispatch is required based on the input of the dispatch rescue personnel. The dispatch control unit (37) can control the display of a safe evacuation route when it receives a safe evacuation route generated based on at least one risk area detected by the risk detection unit (22) from the server (20).

The user terminal (40) can be controlled to display a safe evacuation route when it receives a safe evacuation route generated based on at least one risk area detected from the risk detection unit (22).

Figure 2 is an example of an information display type induction light (1).

Fig. 2 (a) is an example of an evacuation information display type guidance light. Above the emergency light unit (13), the information display unit (14) provides guidance information that a fire has broken out on the 7th floor and the phrase “entry possible” indicating that evacuation is possible by entering this emergency exit.

Fig. 2 (b) is an example of a stairway information display type guidance light. Above the emergency light unit (13), the information display unit (14) provides guidance information that a fire has broken out on the 7th floor and a phrase indicating that evacuation is possible using this stairway.

통로를 이용하여 대피할 수 있다는 것을 나타내는 진입가능의 문구를 정보표시부(14)가 제공하고 있다.Fig. 2 (c) is an example of a guidance light for a two-way corridor. Information indicating that a fire has occurred on the 7th floor is displayed on the upper side of the emergency light unit (13).

The information display section (14) provides an accessible text indicating that evacuation is possible using the passage.

Fig. 2 (d) is an example of a corridor passage (one-way) information display type guidance light. Above the emergency light unit (13), the information display unit (14) provides guidance information that a fire has broken out on the 7th floor and a phrase indicating that evacuation is possible using this corridor passage.

Figure 3 is an example of providing evacuation direction information as a 3D map.

It provides a 3D map of the interior of the building and displays evacuation routes.

Here, AI path calculation algorithms need to be improved.

The AI high-speed path-creation algorithm is an algorithm (Time-Expanded Min Cost Max Flow Evacuation Algorithm) that detects disaster situations and calculates high-speed evacuation routes in real time according to the spread and change status.

Based on the evacuation route data generated through the evacuation route design SW, an evacuation route can be calculated at ultra-high speed within seconds by reflecting the level of congestion.

Evacuation route information is converted into operation information for information display-type guidance lights, and evacuation information is automatically provided through information display-type guidance lights based on LoRa wireless communication.

Using the results of the algorithm execution, it indicates whether it is possible to enter the information display type guidance light (except for the variable guidance light according to the congestion, it does not provide specific direction information, and can only guide the validity of the guidance light display section information by considering the fire location information).

Through the above algorithm, compared to the existing emergency exit guidance method, the evacuation flow can be maximized by inducing as much flow as possible from the waiting area based on the Max Flow Algorithm, so that all people inside the building can escape to a safe area in a short period of time.

In addition, by additionally applying the Min Cost Max Flow Algorithm, an algorithm that minimizes the travel time by considering the travel time between each point in the Max Flow Algorithm, a route that allows for the fastest escape among various evacuation routes can be selected.

The bottleneck that occurs when people are continuously evacuated along a specific route without considering the time can be solved by using the Time Expanded Method to select an available route that is not crowded every hour.

An evacuation guidance platform linked to risk detection equipment such as firefighting equipment, CCTV, and IoT sensors can be applied.

Digital twin control software for disaster response decision support can implement real-time risk zone confirmation and setting and one-click evacuation guidance execution functions through a 3D control screen.

In addition, it can be linked with existing fire-fighting equipment (fire receivers, fire detectors, transmitters, fire shutters, etc.) and CCTV for automatic danger zone display.

And it can support digital twin control with information display-type guidance lights, wireless repeater power, sensors, battery status, communication status, etc. installed on site.

Information display-type guidance lights that guide disaster situation detection and response techniques are installed on major movement lines within a building and are used for monitoring and training purposes in normal times to prevent accidents, and in the event of a disaster, they can support quick and safe evacuation from the installation location.

In addition, it can detect the on-site situation at the initial stage of risk occurrence and spread, transmit it to a wireless repeater, and perform the role of a virtual safety manager before safety managers are deployed to the site.

The LPWA wireless repeater and communication firmware, which is the first in Korea to receive KC certification, can transmit various IoT sensor information to a server, and transmit operation settings based on the results from the server to an IoT location guidance device (with self-developed firmware).

In addition, it supports a wide-area communication range (based on straight-line distance) of several hundred meters*?*1km in the city and more than 15km in open spaces outside the city, and can use ultra-low power (Range@10mW) to perform communication within the communication range.

Figure 4 is an example of evacuation direction information and evacuation possibility information including disaster and risk occurrence locations.

The optimal evacuation route is calculated by synthesizing the location, spread, and number of people of the disaster and risk, and is displayed on a 3D map. Although the names and signs of restrooms and other easily identifiable locations are not displayed on the 3D map, these are provided to make it easier for evacuees to identify the evacuation route.

In addition, the optimal evacuation route for each location can be continuously modified and created based on the location and spread of the disaster and risk, and can be provided by displaying it on a 3D map.

Figure 5 is an example of a technology for judging pedestrian density using AI image analysis.

Pedestrian density assessment technology can be utilized through AI image analysis.

AI video analysis, such as CCTV or AI machine vision sensors installed in buildings, can analyze data on pedestrian objects and traffic flow by location.

By projecting the density and movement of pedestrian objects onto a 3D space model, the traffic volume in each walking direction can be estimated.

Information display-type guidance lights can be used on passageways/stairs, etc. to guide the variable walking patterns of occupants.

Figures 10 and 11 are examples of information display type induction lights.

Figure 10 (a) shows that you can evacuate by passing through the emergency exit by marking OX on the left and right sides of the emergency exit sign.

Fig. 10 (b) Since it has not been confirmed that it is possible to evacuate by passing through this emergency exit, no O marks are displayed on the left and right sides of the emergency exit sign. An X mark could also be displayed here to indicate that entry is not permitted.

Figure 11 can be used to add a direction and an X-mark like a traffic light to the emergency light unit to intuitively notify evacuees.

Described are embodiments that can be modified other than the above embodiments.

The server control unit (23) can control the transmission of information such as safe evacuation routes, guidance broadcasts, fire locations, evacuation direction information, and evacuation availability information to user terminals and dispatch terminals while blocking all frequencies within the building. This can enable safe evacuation by focusing on evacuation.

Information display type guidance lights can further include a speaker. This speaker can be controlled to provide evacuation information to evacuating personnel by voice. In cases where a fire occurs and smoke is present on the evacuation route, it may be difficult to accurately confirm the evacuation route with the eyes, so information such as the location of the fire, evacuation direction information, and evacuation availability information can be provided by voice.

Information display type guidance lights may further include a lighting unit. In the case of smoke on the evacuation route, evacuees may not be able to see the emergency light unit. In order to cope with this, evacuation direction information may be provided in the form of a voice through a speaker, but this voice information may not be heard due to the surrounding disaster situation, so evacuees may not be able to accurately determine the evacuation route. Therefore, the evacuation route may be guided through the lighting unit. This lighting unit may be highlighted, flashed, and moved to assist and guide evacuees in their evacuation.

The main board of the information display type induction light and the communication/main board of the information display section are structurally separated, so even if a defect or failure occurs in the communication/main board of the information display section, it does not affect the normal operation of the information display type induction light.

Due to the above information display type guidance light (1), in the event of a danger such as a fire in a building, the location of the fire, information on the direction of evacuation, and information on whether evacuation is possible are provided to evacuees, so evacuees can safely evacuate by looking at this information, thereby improving safety against danger.

In addition, since evacuees can accurately check the emergency lighting unit and immediately determine whether the lighting in the light output unit has reached the end of its life or is broken, they can safely prepare for danger by repairing or replacing the lighting in the light output unit.

In addition, since it is possible to immediately determine whether the power supply unit has reached the end of its life or has broken down, it is possible to safely prepare for danger by repairing or replacing the power supply unit, and since information about the location of the fire, evacuation direction, and whether evacuation is possible is provided to evacuees in text format, accurate information about evacuation can be delivered.
