Smart street lighting system for electric vehicle charging and fire response

[0001] The present invention relates to a smart street light system for electric vehicle charging and fire response, and more specifically, to a technology that simultaneously increases the convenience of electric vehicle charging and the efficiency of fire response in an urban environment by integrating an electric vehicle charging function and a function to detect and extinguish a fire in the event of a fire into a street light.

[0002] The present invention aims to provide a smart street lighting system that reduces the risk of fire that may occur with the increase in electric vehicles, provides charging infrastructure to electric vehicle users, and simultaneously minimizes damage through initial response in the event of a fire.

[0003] The technology forming the background of this invention relates to electric vehicle charging infrastructure and fire response systems in a smart city environment. With recent urbanization, the use of electric vehicles has increased rapidly, and consequently, the establishment of efficient charging infrastructure in public places has emerged as a critical task. Existing electric vehicle charging systems are limited to dedicated charging stations, resulting in low accessibility and space efficiency; furthermore, in the event of a fire in a public place, the difficulty of initial firefighting leads to the escalation of damage.

[0004] Furthermore, as urban infrastructure, the utility of streetlights is increasing by integrating various smart functions in addition to their lighting capabilities. Smart streetlights have a high potential to serve as networked infrastructure in urban environments and can perform diverse roles due to advancements in sensor and control technologies. However, existing smart streetlights are primarily focused on improving energy efficiency and collecting public data, and there is a lack of examples where practical safety and convenience features, such as electric vehicle charging and fire response, are combined.

[0005] Accordingly, the development of a smart street lighting system integrating electric vehicle charging and fire response functions has become an important technical challenge for simultaneously ensuring space utilization and safety in urban environments. To address this issue, the present invention proposes a system that combines an electric vehicle charging function with a fire extinguishing device in a smart street light, enabling efficient electric vehicle charging and rapid response in the event of a fire.

[0006] The prior art 'Electric Vehicle Charging Station Fire Detection and Fire Handling System' (Application No.: KR1020230065791) contains information regarding a system for early detection and rapid response to fires at electric vehicle charging stations.

[0007] The problem that the present invention aims to solve is to resolve the inconvenience caused by the lack of electric vehicle charging infrastructure and to provide an accessible charging system to electric vehicle users. Furthermore, to address the issue of damage escalating due to delayed initial response in the event of an electric vehicle fire, the invention aims to enable a rapid and effective response in the event of a fire by integrating a fire detection and extinguishing device into a street lighting system. In addition, the invention seeks to overcome the limitations of existing streetlights, which are restricted to simple lighting functions, and to simultaneously secure spatial efficiency and safety in the urban environment through smart streetlights capable of performing multi-functional roles. To solve these problems, the present invention proposes a smart street lighting system capable of integrally performing electric vehicle charging, fire detection, and extinguishing.

[0008] As a means to solve the problem of the present invention, the present invention provides a smart street light system for electric vehicle charging and fire response. The smart street light is connected to an MCU device via a wired / wireless network and is equipped with a lighting unit, a fire detection sensor unit, and an electric vehicle charging unit in its body. The MCU device generates fire occurrence information indicating that a fire has occurred based on data detected by the fire detection sensor unit, and controls a fire extinguishing device based on this information.

[0009] The fire extinguishing device includes a suffocation fire extinguishing cover, which forms a sealed space by covering a parked electric vehicle. In addition, the suffocation fire extinguishing cover includes at least one openable emergency exit and a light source to guide the emergency exit, thereby ensuring both safety and effectiveness during the fire extinguishing process.

[0010] The smart street light system of the present invention performs multifunctional roles of electric vehicle charging and fire response in addition to the basic functions of a street light, thereby simultaneously solving the problem of insufficient electric vehicle charging infrastructure and the problem of initial response in the event of a fire in an urban environment.

[0011] The present invention has the effect of enhancing the convenience of electric vehicle users and solving the problem of insufficient charging stations in urban environments by effectively providing electric vehicle charging infrastructure in public places through a smart street light system that integrates electric vehicle charging and fire response functions.

[0012] In addition, a rapid and effective response is possible in the event of a fire through a fire extinguishing device including fire detection sensors and suffocation fire extinguishing covers, thereby minimizing damage caused by the spread of fire by extinguishing the initial fire.

[0013] By assigning multifunctional roles such as electric vehicle charging and fire response to streetlights in addition to their existing lighting functions, the utilization of urban space can be maximized, and the safety and efficiency of the urban environment can be improved by utilizing the network and sensor technologies of smart streetlights.

[0014] Furthermore, safety is ensured during the fire extinguishing process through a fire suppression device including a suffocation fire suppression cover and a luminescent element, and safe fire response is possible by providing a structure that allows users to evacuate in an emergency. In this way, the present invention provides the effect of contributing to the establishment of a safe and efficient smart infrastructure in an urban environment.

[0021] Various embodiments are described with reference to the drawings. In the present invention, various descriptions are provided to facilitate an understanding of the invention. However, it is evident that these embodiments can be practiced without such specific descriptions.

[0022] The term "or" is intended to mean an implicit "or" rather than an exclusive "or." That is, unless otherwise specified or evident from the context, "X uses A or B" is intended to mean one of the natural implicit substitutions. In other words, if X uses A; if X uses B; or if X uses both A and B, "X uses A or B" may apply to any of these cases. Furthermore, the term "and / or" as used in this invention should be understood to refer to and include all possible combinations of one or more of the enumerated related items.

[0023] Furthermore, the terms “comprising” and / or “comprising” should be understood to mean that such features and / or components are present. However, the terms “comprising” and / or “comprising” should be understood not to exclude the presence or addition of one or more other features, components and / or groups thereof. Additionally, unless otherwise specified or clearly evident from the context to indicate a singular form, the singular in the present invention and claims should generally be interpreted to mean “one or more.”

[0024] And, the term “at least one of A or B” should be interpreted to mean “a case including only A,” “a case including only B,” and “a case combined with the composition of A and B.”

[0025] In embodiments of the present invention, unless the subject is specified, the operations may be understood to be performed by the MCU device (200). The MCU device (200) is a type of computing device and can integrally control various components within the smart street light system. For example, the MCU device can perform the role of processing data detected from the fire detection sensor unit to generate fire occurrence information and operating the extinguishing device based on said information. In addition, it can manage the overall operation of the smart street light system by controlling the power supply of the electric vehicle charging unit or by receiving and processing remote control signals through a network.

[0026]

[0027] FIG. 1 is an exemplary diagram showing the components of an entire system according to one embodiment of the present invention.

[0028] FIG. 1 is an exemplary diagram showing the components of an entire system according to one embodiment of the present invention, illustrating the main components of a smart street light system (10) and the interactions between them. The system includes at least one smart street light (100) and an MCU device (200) for performing electric vehicle charging and fire response functions.

[0029] The smart street light (100) is equipped with a lighting unit (130), a fire detection sensor unit (120), and an electric vehicle charging unit (110), and each component is integrally controlled by a central control unit. The lighting unit performs the basic lighting function of a street light and is responsible for ensuring nighttime visibility in an urban environment. The fire detection sensor unit includes a sensor for detecting whether a fire has occurred and transmits the corresponding data to the central control unit. The electric vehicle charging unit provides power supply for charging an electric vehicle and is designed to respond to the user's charging needs.

[0030] The central control unit serves as the central control unit for smart streetlights. It is connected to the outside world via wired or wireless networks and controls the entire system by processing data collected from each component. For example, if the fire detection sensor determines that a fire has occurred, the central control unit generates fire occurrence information and controls the operation of the extinguishing device based on this information. The extinguishing device includes a suffocation extinguishing cover that forms a sealed space by covering the electric vehicle in the event of a fire, thereby preventing the spread of the fire.

[0031] In addition, the above system can be remotely managed and controlled via a network, and the status of the system can be monitored and operated in real time through a user interface or a cloud-based platform.

[0032] At this time, the fire detection sensor unit may include a flame detection sensor, a heat detection sensor, and a smoke detection sensor to detect whether a fire has occurred at an early stage. For example, if the battery of a parked electric vehicle overheats and heat accumulates, and the heat detection sensor detects this, the system of the present invention determines that a fire has been detected and can perform corresponding actions.

[0033] The above MCU device collects data from the fire detection sensor unit and the license plate recognition unit, analyzes it, and determines whether a fire has occurred. If a fire occurs in a vehicle that is being charged, the MCU device can immediately cut off the charging unit and activate the fire extinguishing device.

[0034] The fire extinguishing device includes at least one of a sunshade type or a bellows type suffocation fire extinguishing cover, which extinguishes the fire or prevents its spread by covering the electric vehicle to form a sealed space when a fire occurs (described in detail later).

[0035] The system of the present invention may additionally include a server. The server can store and analyze fire occurrence information received from the MCU device and transmit commands back to the MCU device. The server can communicate with the control center and fire department to send a warning when a fire occurs and monitor the fire situation in real time. In addition, the server (150) sends a warning message to a user terminal so that the user can immediately recognize the fact that a fire has occurred and take action.

[0036] In the system of the present invention described above, the control center refers to a central control system that monitors and manages smart streetlights in real time. A control center in the form of a management office can detect abnormal situations that may occur during electric vehicle charging, such as a fire, in real time, and perform roles such as immediately transmitting a warning through the system and operating a fire suppression device when a fire occurs.

[0037] Meanwhile, fire departments are external agencies that respond urgently to the occurrence of a fire, with the 119 Safety Center being a representative example. The system of the present invention can immediately transmit fire occurrence information generated when a fire is detected by a fire detection sensor to the fire department via a server. Through this, the fire department can quickly dispatch and proceed with fire suppression.

[0038] In a system according to an embodiment of the present invention, the electric vehicle charging unit charges the electric vehicle but receives a signal from the MCU device in the event of a fire and immediately stops charging. This prevents additional electrical risks caused by fire. For example, if a fire occurs due to a battery malfunction in an electric vehicle being charged, the electric vehicle charging unit can receive instructions from the MCU device and immediately cut off the current supply.

[0039] In a system according to an embodiment of the present invention, the flame detection sensor detects an ultraviolet (UV) wavelength of 200 nm to immediately output a signal upon the occurrence of a fire, and can operate accurately without interference from electric lights or visible light. The heat detection sensor detects a rapid temperature rise occurring in a parking lot or charging station to detect the possibility of an initial fire, and the smoke detection sensor can detect smoke caused by the fire early and transmit a warning to the system. By operating these various sensors in combination, the system can recognize the fire early and respond quickly. For example, if the smoke detection sensor detects smoke during the initial stage of battery ignition where flames are not visible, the system quickly issues a warning.

[0040] In a system according to an embodiment of the present invention, the license plate recognition unit includes an infrared LED module and an RGB camera, and performs the role of recognizing and recording the license plates of vehicles entering a parking lot or charging station. The infrared LED module can clearly recognize license plates even in low-light environments, and the RGB camera reads the colors and characters of the license plate to transmit information about the corresponding vehicle to the system. Through this, it is possible to identify whether a fire has occurred while a specific vehicle is parked and to support an accurate response. For example, after identifying the license plate of a vehicle charging at night using the infrared LED module, the system can track and respond to a fire that has occurred in that vehicle.

[0041] In addition, the present invention may include a fire detection and response system via a mobile application as an additional embodiment. The vehicle owner can monitor the status of the parked vehicle in real time through the mobile app and receive an immediate warning in the event of a fire. For example, when a fire is detected by the system, a push notification is sent to the user, allowing the vehicle owner to immediately identify the fire situation in their vehicle. Furthermore, the user can check the fire response status in real time through the mobile app and take additional measures if necessary. This system is particularly useful when the vehicle owner is away from the vehicle and provides a means to respond quickly in the event of a fire.

[0042]

[0043] FIG. 2 is an illustrative diagram showing an example of a sunshade-type firefighting device deployed according to one embodiment of the present invention.

[0044] Referring to FIG. 2, an example of a smart street light including a sunshade suffocation fire extinguishing cover according to one embodiment of the present invention is shown. The sunshade type fire extinguishing device serves to extinguish a fire by covering a vehicle with the suffocation fire extinguishing cover when a fire occurs.

[0045] The sunshade-type suffocation fire extinguishing cover operates by descending to cover the electric vehicle. In the event of a fire, the cover descends from the top of the vehicle to the floor, forming a sealed space, and then protects the vehicle from the fire by spraying liquid extinguishing agents, such as carbon dioxide or water, through a water supply system. This method offers the advantage of not only covering the vehicle and cutting off the oxygen supply but also rapidly suppressing the fire by directly spraying the extinguishing agent.

[0046] Furthermore, the sunshade suffocation fire extinguishing cover does not structurally occupy much space, allowing it to be used in large electric vehicle charging stations or parking lots with many vehicles, and provides the flexibility to adapt to various fire situations. When combined with an energy self-sufficiency system using solar panels, it enables environmentally friendly operation and offers the advantage of operating safely without an additional power supply during fire response.

[0047] However, if a sealed space is formed around an electric vehicle by the sunshade suffocation fire extinguishing cover method, the risk of safety accidents may increase when a person is inside. To mitigate this risk, it is desirable to provide a warning sound or voice guidance and to include an escape opening (e.g., a) at least 2 meters high inside the sunshade suffocation fire extinguishing cover. This escape opening may be designed to be easily opened and closed using a method such as a zipper, magnetic material, or Velcro so that a person can use it quickly.

[0048] This can facilitate escape in emergency situations. For example, while the risk of suffocation may increase in enclosed spaces without escape routes, installing escape routes closed with zippers, magnetic materials, or Velcro allows for quick escape, significantly reducing the likelihood of safety accidents.

[0049] In addition, since the interior of a confined space can be blocked from light and filled with gas during a fire, the location of the escape route must be easily identifiable. To address this, marking escape routes with phosphors or luminescent materials is effective. Text or marks labeled 'Escape Route' using phosphors or luminescent materials are easily visible even in dark environments and help clearly recognize the location of the escape route. For example, a mark displayed in phosphors allows the location of the escape route to be quickly found even in a lightless, enclosed space, enabling a rapid response in chaotic situations.

[0050] In one embodiment, the longitudinal edges of a sealed space may be designed with temporary fasteners such as magnetic materials or Velcro. When designed in this way, it provides an option for a user to escape by rushing against the wall in any direction when trapped inside. This significantly enhances safety by creating the possibility of temporarily separating the sealed wall to escape even if an escape route cannot be found. For example, a temporary fastener method using magnetic materials or Velcro can enable an emergency escape by allowing the user to forcefully open the wall and escape in critical situations while maintaining the structural durability.

[0051] When forming a sealed space using a sunshade suffocation fire extinguishing cover, a problem may arise where the sealed space is not fully formed due to the charging coupler and cable connected to the electric vehicle becoming entangled. As a solution to this, a system can be introduced that automatically disconnects the connection between the charging unit and the cable when the electric vehicle charging unit receives a fire signal from a server or MCU, thereby physically dropping the cable to the ground. This system helps to quickly form a completely sealed space without obstacles and physically prevents further power supply to the electric vehicle. For example, if the cable does not drop, the sealed space is not fully formed, which may reduce the fire extinguishing effect; however, if the cable is quickly removed through the automatic release system, the fire extinguishing system can operate normally, significantly improving the efficiency of fire suppression.

[0052] Meanwhile, as an embodiment, a solar panel may be included on the upper part of a sunshade-type suffocation fire extinguishing cover. This solar panel is normally used to generate energy for charging electric vehicles, and the energy collected through the solar panel can be used in the electric vehicle charging unit or lighting unit. The system is environmentally friendly and can be operated using a self-power supply method. In this case, when using a solar panel, it is desirable to manage the electricity between the solar panel and the battery through an ESS device. This can be effective in emergency situations such as a power outage, when a fire occurs, or when it is difficult to connect a wired power source.

[0053]

[0054] FIG. 3 is an exemplary diagram showing a case where a sunshade-type fire extinguishing device according to one embodiment of the present invention is located outside a street light.

[0055] This shows the configuration of a sunshade-type fire extinguishing device installed in a separate location from a smart street light. In this case, the smart street light and the sunshade-type fire extinguishing device operate independently, but are configured to enable mutual communication through an MCU.

[0056] Smart streetlights detect the occurrence of a fire through fire detection sensors and a network, and transmit this information to an MCU unit. The MCU unit processes the fire occurrence information and sends the corresponding signal to an external awning-type fire suppression device. Upon receiving the signal, the awning-type fire suppression device deploys a suffocation fire extinguishing cover to enclose the burning electric vehicle and form a sealed space. Subsequently, it performs the process of spraying fire extinguishing fluids, such as carbon dioxide or water, to suppress the fire.

[0057] As such, the externally positioned sunshade-type fire extinguishing device is physically separated from the streetlight but can operate in close cooperation based on communication via an MCU. This configuration allows the device to activate immediately from a location closer to the fire site, thereby increasing the efficiency of fire suppression.

[0058] Furthermore, the externally positioned sunshade-type fire extinguishing device offers spatial layout flexibility and can be effectively used in various environments, such as large parking lots or charging stations. This independent placement method provides the advantage of establishing a customized fire response system tailored to specific locations. In particular, when combined with the sensor and network capabilities of smart streetlights, it enables the automation and integrated management of fire response.

[0059]

[0060] FIG. 4 illustrates a case in which a bellows-type fire extinguishing device according to one embodiment of the present invention is independently positioned outside a smart street light, and exemplarily shows a system that responds quickly to a fire by utilizing a bellows suffocation fire extinguishing cover that includes a canopy function.

[0061] In this embodiment, an accordion-type suffocation fire extinguishing cover is installed externally so that fire detection and response can be performed independently of the smart streetlight, and it communicates and interacts with the smart streetlight through an MCU device. When a fire occurs, a sensor mounted on the smart streetlight detects it and transmits data to the MCU device. After processing the fire signal, the MCU device activates the externally installed accordion-type suffocation fire extinguishing cover to cover the electric vehicle where the fire occurred and form a sealed space. Once the sealed space is formed, the accordion-type suffocation fire extinguishing cover cuts off the oxygen supply and sprays extinguishing liquid to suppress the fire.

[0062] In particular, FIG. 4 shows an example that can be flexibly applied depending on the condition of a vehicle in a parking space by utilizing the structural characteristics of the bellows type. For example, whether an electric vehicle is parked in the parking space is checked via a camera or sensor, and when a fire detection sensor detects a rise in the vehicle's temperature, smoke, or flames, the system automatically operates to deploy the bellows suffocation fire extinguishing cover.

[0063] The accordion-type suffocation fire extinguishing cover is designed to completely envelop the vehicle when deployed. It includes a canopy function to protect the vehicle and its surroundings while preventing the spread of fire. During this process, the MCU unit emits a warning siren and voice broadcasts to notify nearby residents of the fire and guide them to evacuate. Additionally, through communication between the MCU unit and the server, fire information is transmitted in real-time to control centers or fire departments, enabling rapid external support.

[0064]

[0065] FIG. 5 is the first flowchart illustrating the operation method of a system according to one embodiment of the present invention.

[0066] Referring to FIG. 5, in one embodiment, an MCU device acquires camera images to monitor the condition of a parking space, and when an electric vehicle enters the parking space, the MCU device recognizes the license plate and location of the vehicle through the camera to verify whether the vehicle is parked correctly.

[0067] At this time, if the presence of a vehicle in the parking space is confirmed, the system can automatically activate the fire detection sensors. These sensors can operate in various ways to detect the occurrence of a fire; flame detection sensors detect sparks that may emanate from the vehicle, while smoke detection sensors detect smoke early that may be caused by battery overheating or other electrical issues. Additionally, heat detection sensors monitor temperature changes in the parked electric vehicle to detect a rapid rise in temperature. Furthermore, an RGB image analysis function has been added, allowing for the determination of whether a fire has occurred by analyzing visual changes around the vehicle via real-time camera footage.

[0068] When a fire is detected, a sunshade / accordion fire suppression cover with a canopy function activates immediately. This canopy serves to extinguish the fire by covering the vehicle and cutting off the oxygen supply. In addition, a fire alert function is performed simultaneously. In the event of a fire, the system sounds a siren and emits a warning sound, notifying people in the parking lot of the fire via voice broadcast. For example, a broadcast such as "Fire! Evacuate immediately!" can be transmitted through speakers in the parking lot to encourage rapid evacuation.

[0069] The preceding embodiment can operate independently without a separate server (150) or external communication device, and the system can automatically operate to respond immediately when a fire occurs. In particular, it has the advantage of being able to suppress the fire before it spreads into a larger accident by responding quickly to a fire that may occur during electric vehicle charging. For example, even when the vehicle owner is away, the system can independently detect a fire and activate a fire extinguishing device to protect the vehicle and surrounding facilities.

[0070] An additional embodiment related to the above-described automatic method may include a system capable of operating even in low-power conditions. This method may include an emergency power supply to enable the standalone system to continue operating even in situations where the power supply is interrupted or a power outage occurs. This emergency power continuously supplies power through a battery or a solar power generation system, supporting the operation of the MCU device, sensors, and fire extinguishing device without power shortage. For example, even in the event of a power outage, the system can independently supply power to detect and respond to a fire that may occur in the vehicle.

[0071] In another embodiment, temperature and humidity control functions may be added. This method involves continuously monitoring the temperature and humidity around the smart streetlight and sending a warning if abnormal signs are detected. By managing the environment inside the parking lot in real time, this provides an additional protective function that can prevent fire risks in advance. For example, if the temperature in the parking lot rises sharply or humidity drops significantly, increasing the risk of fire, the system can detect this and send a warning, thereby contributing to fire prevention.

[0072]

[0073] FIG. 6 is a second flowchart showing the operation method of a system according to one embodiment of the present invention.

[0074] When an electric vehicle enters a charging parking space, the MCU device can activate multiple sensors to verify whether the vehicle is properly parked in the parking space. At this time, it recognizes the vehicle's license plate and checks whether the vehicle is parked in a moved position. If it is confirmed that the vehicle is properly parked in the parking space, the system monitors whether charging begins within a predetermined time. If charging begins within this time, the MCU device can issue a command to perform an electric vehicle fire detection operation.

[0075] In this process, the fire detection operation monitors for the occurrence of a fire through the simultaneous operation of multiple sensors, such as flame, smoke, and heat sensors. Additionally, the RGB video fire analysis function is activated to analyze visual changes in real-time via camera footage. If a fire is identified during this process, the system immediately executes fire response actions. First, the fire situation is transmitted to the server, which then instructs the MCU to control the electric vehicle charging unit to immediately halt charging. Simultaneously, a fire suppression device activates to cover the electric vehicle and cut off the oxygen supply, thereby extinguishing the fire.

[0076] During this process, the server immediately transmits fire alerts to the control center, fire departments, and the vehicle owner's user terminal. This allows the control center to quickly assess the situation and respond, while the owner receives notifications about the fire in their vehicle. The server also disseminates the fact of the fire to fire departments to initiate an urgent external response, and the MCU device alerts nearby people in the parking lot to the fire via siren warnings and voice broadcasts through speakers that can be integrated into smart streetlights. For example, a voice message such as "Fire! Evacuate immediately!" is transmitted through speakers within the parking lot.

[0077] Conversely, if vehicle charging does not begin within a predetermined time, the server instructs the MCU to output a voice message stating, "If you are not charging, please move the vehicle to another parking location." This encourages the user to move the vehicle and verifies whether the relocation has been completed within a set period. If the vehicle is not moved, the situation is reported to the control center, including the vehicle owner and the management office. This process may be repeated until the vehicle begins charging or is successfully moved.

[0078] This method is designed to ensure that the vehicle is properly parked and charging is proceeding normally, and to enable the system to detect and respond in advance to the possibility of a fire occurring during charging.

[0079] In one embodiment, if the vehicle owner does not move the vehicle or start charging within 5 minutes after hearing the warning, the system automatically notifies the vehicle owner's terminal and the control center of this fact. At this time, the system may also send an additional voice alert to the user saying, "If you do not move within the specified time, it will be reported to the control center."

[0080] If the vehicle is not moved within 15 minutes after a warning message is sent to the control center, the system provides a detailed notification including the vehicle owner and relevant information so that the management office can handle it. This action is repeated until the vehicle starts charging or is moved to a parking position.

[0081] In this way, the system enables efficient parking and charging management of vehicles through a series of procedures in which it detects whether charging has started within 10 minutes in the electric vehicle parking lot, sends a notification to the user within 5 minutes, and reports to the management office within 15 minutes. This not only helps with the efficient management of vehicles waiting to charge but is also an important preventive measure that can reduce the risk of fire caused by battery overheating or other problems resulting from long-term parking.

[0082]

[0083]

[0084] The contents of the present invention are briefly reviewed.

[0085] The present invention provides a smart street light system for electric vehicle charging and fire response. The smart street light is connected to an MCU device via a wired or wireless network, and the street light body is equipped with a lighting unit, a fire detection sensor unit, and an electric vehicle charging unit. This system integrally provides a function capable of rapidly responding to a fire, along with an electric vehicle charging function.

[0086] The MCU unit of the smart streetlight system processes data collected from the fire detection sensor to determine whether a fire has occurred and generates fire occurrence information. Based on the generated fire occurrence information, the MCU unit activates the fire extinguishing device to control the fire and prevent its spread. The fire extinguishing device includes a suffocation fire extinguishing cover, which serves to suppress the fire by covering the parked electric vehicle to form a sealed space and cutting off the oxygen supply in the event of a fire. This cover includes at least one openable emergency exit inside and is equipped with a light source to guide the location of the emergency exit, enabling safe escape in emergency situations.

[0087] The suffocation fire extinguishing cover can be implemented in various ways. One method includes a sunshade-type suffocation fire extinguishing cover, which descends from the top of the electric vehicle to the ground to form a sealed space. A water supply device that sprays extinguishing liquid is positioned within the sealed space, allowing for the rapid and effective suppression of a fire in the event of a fire.

[0088] Another method involves a suffocation fire extinguishing cover adopting an accordion structure. Upon receiving information about a fire, the accordion suffocation fire extinguishing cover deploys toward the front of the parked electric vehicle to form a sealed space. This method offers flexibility in space utilization and is effective in preventing the spread of fire. Furthermore, it can prevent additional damage caused by the fire by generating fire detection information based on data detected by the license plate recognition unit and cutting off power to the relevant electric vehicle charging unit.

[0089] The accordion-type suffocation fire extinguishing cover consists of an accordion device, a motor to deploy it, and a guardrail. In the event of a fire, the accordion device deploys to completely cover the electric vehicle, creating a seal against the outside, and is designed to ensure effective fire suppression.

[0090] Additional embodiments of the present invention are disclosed.

[0091] In one embodiment, the lighting unit of the present invention performs the basic lighting function of a street light during normal times, but when the suffocation fire extinguishing cover is deployed, it is positioned inside the enclosed space formed by the deployed cover to perform a special lighting function. This lighting unit provides visual guidance to enable a person to easily escape in an emergency situation inside the enclosed space. When the suffocation fire extinguishing cover is deployed, the lighting unit is automatically activated, taking into account the possibility that the internal environment may become dark. This lighting is designed to highlight the location of the escape route and helps the user easily identify the escape route by flashing light in a specific pattern or continuously illuminating it through a light source. For example, an arrow-shaped light pointing in the direction of the escape route may be provided, or a focused light that brightly illuminates the area around the escape route may be used.

[0092] In one embodiment, when the suffocation fire extinguishing cover is deployed, a situation may arise where it is difficult to easily identify the exact location of the fire from the outside due to the sealed structure. To solve this problem, the lighting unit of the present invention is designed to operate in a special pattern to clearly convey the location of the fire to surrounding fire departments and nearby people in the event of a fire. The lighting unit uses a flashing method with a specific breathing pattern (e.g., repeating a gradual brightening and dimming) in a manner similar to a lighthouse, providing a signal that can be easily recognized from a distance. Such a lighting pattern can intuitively indicate a fire situation, helping fire departments respond quickly. For example, after detecting a fire, the lighting unit may send a strong flashing signal using red light or flash at a specific frequency to visually indicate an emergency situation.

[0093] In one embodiment, during the process of deploying the suffocation fire extinguishing cover of the present invention, a situation may occur where a sealed space is not completely formed or it is difficult for the user to escape due to the door of an electric vehicle or other protruding structures. To prevent such cases, it is desirable for the suffocation fire extinguishing cover to adopt a flexible structure designed not to get caught on structures such as the door of an electric vehicle. For example, the material of the cover may be made of an elastic material, or a flexible sealing structure may be added to the edge of the cover to bypass physical obstacles or maintain a seal.

[0094] In one embodiment, the suffocation fire extinguishing cover of the present invention may include a hose coupler and a valve to enable external firefighting personnel to effectively spray fire extinguishing liquid onto an electric vehicle for fire suppression. This configuration is designed to allow firefighting personnel to deliver the fire extinguishing liquid into the vehicle interior without structural obstruction by the sealed cover when performing firefighting operations from the outside. The hose coupler enables a quick and secure connection with a fire hose and allows the fire extinguishing liquid to flow efficiently into the interior of the cover. The valve is designed to control the flow of the fire extinguishing liquid, allowing firefighting personnel to inject the required amount of liquid in a timely manner. Such a valve is installed externally for easy operation and can be operated quickly and accurately even in emergency situations.

[0095] In one embodiment, the lighting unit of the present invention may be composed of an array of multiple individual LEDs, and each LED in the array may perform the role of outputting characters in a dot manner in addition to providing lighting for information transmission. The LED array can notify users inside or firefighters outside of the situation by outputting short and clear words such as "FIRE," "EXIT," or "HELP" in the event of a fire. The output of characters is controlled by an MCU device and is designed to display information appropriate to the fire situation in real time. For example, when a fire occurs, the LED array may output a "FIRE" message along with a flashing pattern, or provide a guidance message such as "EXIT" if users inside are evacuating.
