Description

Parking structure and parking structure control method

[0001] This application claims the benefit of the filing date of Korean Patent Application No. 10-2024-0157550 filed with the Korean Intellectual Property Office on November 8, 2024, and all contents disclosed in the document of said Korean patent application are incorporated into this specification.

[0002] The present invention relates to a parking structure and a method for controlling a parking structure, and more specifically, to a parking structure that forms a structure to prevent fire spread using a wing bulkhead or a damper, and a method for controlling the same.

[0003] Consumer interest and demand for electric vehicles are increasing as they emerge as the most effective alternative for reducing greenhouse gas emissions and improving energy efficiency. Unlike conventional internal combustion engine vehicles, electric vehicles (EVs) require components such as batteries, electric motors, inverters, converters, and Battery Management Systems (BMS).

[0004] Rechargeable secondary batteries are used for electric vehicles. Secondary batteries, which can be recharged and reused after use, are manufactured into battery modules or battery packs by connecting multiple battery cells in series according to the output capacity required by the electric vehicle, and are used as power sources for various electric vehicles. Secondary batteries are used in a wide range of fields, from small advanced electronic devices such as smartphones to electric bicycles, electric vehicles, and Energy Storage Systems (ESS).

[0005] Electric vehicle (EV) charging stations are generally locations that receive power from the grid to perform slow or fast charging for EVs, often resulting in a high concentration of EVs being parked. However, fires occurring during EV charging or caused by battery overheating have recently become a very serious issue. Lithium-ion batteries, which are primarily used in EVs, have the disadvantage of being particularly vulnerable to fire compared to other types of batteries. Furthermore, the risk of fire can be amplified because battery packs installed in the undercarriage of EVs are manufactured by intensively modularizing and packaging a large number of cells.

[0006] Battery fires are primarily caused by thermal runaway in battery cells. When thermal runaway occurs, the battery cells release stored energy very rapidly, and the greater the energy charged in the cells, the more vigorous the thermal runaway reaction becomes. Therefore, there is a problem in that it is very difficult to suppress electric vehicle fires in their early stages using conventional fire suppression systems.

[0007] A related prior art is Korean Registered Patent No. 2618911.

[0008] The objective of the present invention to solve the above-mentioned problems is to provide a parking structure that forms a structure to prevent fire spread using wing bulkheads or dampers.

[0009] Another objective of the present invention to solve the above-mentioned problems is to provide a method for controlling the parking structure.

[0010] A parking structure according to one embodiment of the present invention for achieving the above objective may include: a parking plate for accommodating a parked vehicle; a plurality of wing bulkheads installed on the side or bottom surface of the parking plate; a plurality of dampers supporting the parking plate; a valve for controlling the expansion and contraction of the dampers; and a control device for controlling the flow of a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate or controlling the shape of the dampers to change when a fire occurs in the vehicle.

[0011] The above parking structure may further include a fire extinguishing agent inlet disposed on the side or bottom surface of the parking plate, and the control device may control the fire extinguishing agent inlet so that the fire extinguishing agent flows into the space formed by the plurality of wing bulkheads and the parking plate when a fire occurs in the vehicle.

[0012] The above parking structure may also further include a tank positioned below ground and formed to a size capable of accommodating a vehicle.

[0013] Here, if the control device determines that a fire remains even after a certain period of time has elapsed since the fire extinguishing agent was introduced into the space formed by the plurality of wing bulkheads and the parking plate, it can control the valve to drop the vehicle into the water tank.

[0014] Here, the plurality of dampers includes a first damper supporting a part of the parking plate; and a second damper supporting a part of the parking plate, and the first damper and the second damper can be connected to the valve through an air inlet / outlet passage.

[0015] At this time, in a normal situation where no fire occurs, the valve is maintained in a closed state, the first damper is maintained in a maximum compressed state, and the second damper is maintained in a maximum expanded state, so that the parking plate can be supported in a balanced state.

[0016] The above control device can control the valve to an open state in the event of a fire, thereby releasing the expansion state of the second damper through the air inlet / outlet passage and switching the parking plate to a non-equilibrium state.

[0017] Here, the first damper and the second damper are connected to a fixed shaft through a support and can be provided in a form that allows them to move up and down by the weight applied to the parking plate.

[0018] Meanwhile, the above valve is mounted above the space where the vehicle is parked, and can be changed to an open state by the high temperature of the space where the vehicle is parked.

[0019]

[0020] A method for controlling a parking structure according to an embodiment of the present invention for achieving the above other objectives is a method for controlling a parking structure comprising a plurality of wing bulkheads installed on the side or bottom surface of a parking plate, a plurality of dampers supporting the parking plate, and a valve controlling the expansion and contraction of the dampers, and may include the steps of: determining whether a fire occurs in a vehicle parked on the parking plate; and, when a fire occurs in the vehicle, controlling the flow of a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate or controlling the shape of the dampers to change.

[0021] Here, the step of controlling one or more of the plurality of wing bulkheads and the valve may include: the step of moving and positioning the plurality of wing bulkheads so that the plurality of wing bulkheads surround the side of the parking plate; and the step of controlling a fire extinguishing agent inlet so that a fire extinguishing agent is introduced into the space formed by the plurality of wing bulkheads and the parking plate.

[0022] The step of controlling one or more of the plurality of wing bulkheads and the valve may further include the step of controlling the valve to drop the vehicle into a water tank placed below the ground if a fire remains after a certain period of time has elapsed after introducing a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate.

[0023] Here, the plurality of dampers includes a first damper supporting a part of the parking plate; and a second damper supporting a part of the parking plate, and the first damper and the second damper can be connected to the valve through an air inlet / outlet passage.

[0024] Meanwhile, the step of controlling one or more of the plurality of wing bulkheads and the valve may include, in the event of a fire, controlling the valve to an open state to release the expansion state of the second damper through the air inlet / outlet passage and switching the parking plate to a non-equilibrium state.

[0025] According to the embodiment of the present invention as described above, fires that may occur in parking lots where vehicles with a high risk of fire, such as electric vehicles, are parked can be detected and addressed at an early stage. Accordingly, a safer parking environment can be provided.

[0043]

[0044] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0045]

[0046] Figure 1 illustrates the structure of a typical parking tower with a mechanical parking system.

[0047] Due to the shortage of parking spaces resulting from the increase in vehicles and the reduction of available land, multi-story parking towers are being constructed and utilized in densely populated urban areas to accommodate a large number of vehicles on limited land. Parking towers often incorporate mechanical parking systems that eliminate the need for access roads or movement paths. The mechanical parking systems in parking towers operate by utilizing lifting and lowering devices and moving mechanisms to position incoming vehicles into multiple partitioned parking spaces.

[0048] Referring to FIG. 1, a parking tower equipped with a mechanical parking facility comprises a parking body (11) and a lifting container (12). The parking body (11) is provided in the form of a frame that parks the entered vehicles in positions partitioned into multiple floors.

[0049] The parking body (11) may be configured to include a body frame and a parking frame (14). The body frame is configured in a frame shape that is divided into multiple layers for a vehicle to enter and park, has an entry space for a vehicle to enter from the bottom, and has a lifting / lowering space in which a lifting / lowering container (12) is installed in the center for the vehicle to be lifted or lowered.

[0050] The parking frame (14) is positioned in a location partitioned into multiple layers on the body frame and has a parking space on both sides of the lifting / lowering space where a vehicle is parked. Additionally, a transport unit is installed at the bottom of the parking frame (14) and is provided in the form of a frame that moves a vehicle, which has been lifted / lowered by the operation of the lifting / lowering container (12), to both sides by the operation of the transport unit and places it in the parking space.

[0051] The lifting and lowering container (12) is positioned in the center of the parking body (11) and is configured to lift and lower the entered vehicle to transport it to both sides of the partitioned multiple floors, and to seal the vehicle that has caught fire while it is located inside.

[0052] As shown in Fig. 1, in the case of a parking tower equipped with mechanical parking facilities, the parking area can be expanded, but there was a problem in that many vehicles were parked in a small area, and if a fire occurred, it could spread to vehicles filled with fuel, which is a flammable substance, leading to a large-scale fire. In particular, when the parked vehicles are electric vehicles, the risk of fire can be amplified due to the characteristics of the batteries used as a power source.

[0053]

[0054] Figure 2 is a diagram showing the configuration of an on / off board charging system for an electric vehicle.

[0055] Electric vehicles can be classified into HEV (Hybrid Electric Vehicle), PHEV (Plug-in Hybrid Vehicle), EV (Electric Vehicle), FCEV (Fuel Cell Electric Vehicle), etc., depending on the type of power source and battery used.

[0056] HEV (Hybrid Electric Vehicle) is a general term for automobiles that use two types of power, typically utilizing both a conventional engine and electric energy from a battery. Unlike HEVs, PHEVs (Plug-in Hybrid Vehicles) charge their batteries externally; the battery plays the primary role in both starting and driving, with the engine acting as a backup only when the battery is discharged. EVs (Electric Vehicles) are electric vehicles that have enhanced battery capacity compared to PHEVs and have had their engines removed. FCEVs (Fuel Cell Electric Vehicles) are characterized by having their primary power source in a fuel cell that generates electrical energy internally, rather than an externally charged battery.

[0057] The battery used in the electric vehicle (50) must satisfy the conditions of having high energy density to increase the vehicle's driving range and being capable of complete discharge more than a certain number of times. Nickel-hydrogen (Ni-MH) batteries and lithium polymer-based batteries, which have sufficient power density and reasonable charge / discharge energy efficiency, are mainly used as batteries for electric vehicles. The battery is typically mounted in the vehicle in the form of a battery pack (51) that includes a battery module and a Battery Management System (BMS).

[0058] A battery pack (51) may be configured to include one or more battery modules, and circuits, control devices, etc., necessary for managing battery cells and modules. A battery module is an assembly of multiple battery cells connected in series and parallel that are electrically connected. A battery cell is a basic unit that performs the role of storing energy, and the most commonly used battery cell is a lithium-ion (Li-Ion) battery cell.

[0059] In addition, the BMS manages algorithms for driving range prediction, full charging, overcharge prevention, and cell-to-cell equalization. The BMS may also include fault management of battery cells or modules and battery replacement notification functions through battery life prediction. To perform these operations, the BMS includes various components such as fuses, current sensing elements, thermistors, switches, and balancers to monitor the current, voltage, and temperature of battery cells or modules.

[0060] The battery pack (51) can drive the vehicle by supplying power to the electric motor through an inverter (or AC / DC converter) equipped in the vehicle. The BMS of the battery pack can communicate with the ECU and VCU within the vehicle body using a communication method such as the CAN protocol. The BMS reports information related to the battery status to the vehicle and can control the connection status between the vehicle and the battery according to the vehicle's operation information. When the operation of the vehicle ends, the BMS receives a vehicle operation termination signal from the vehicle's ECU or VCU and can stop the power supply that was being delivered from the battery module to the vehicle.

[0061] For the operation of such a vehicle, control operations such as motor drive control, regenerative braking control, air conditioning load control, and electrical load power (12V) supply control are required. The vehicle may include several ECUs (Electronic Control Units) for these control operations.

[0062] Referring to Fig. 2, chargers are classified into on-board chargers and off-board chargers depending on whether they are installed in an electric vehicle, and are further classified into Home, Standard, and Quick based on their purpose of use. On-board chargers include standard chargers and home chargers. Quick chargers are off-board chargers with a power level of 50 kW or higher, and are primarily used to supplement insufficient power for a short period of time at electric vehicle charging stations.

[0063] An onboard charger (52) installed inside an electric vehicle may be configured to include an AC / DC converter, a power flow controller (PFC), and a DC / DC converter. The onboard charger (52) can convert AC power supplied from a grid or a corresponding power supply unit into DC power of an appropriate level and output it. The onboard charger (52) can supply power by connecting to a DC / DC converter connected to a battery pack via a DC bus, an AC / DC converter connected to an electric motor, and a DC / DC converter connected to electrical equipment.

[0064] As seen in Figure 2, the battery pack installed in the lower part of the electric vehicle is exposed to a greater risk of fire because it is packaged by intensively modularizing a large number of cells and adding control circuits, etc.

[0065] In order to solve this problem, the present invention provides a parking structure capable of preventing fires in a parking space where vehicles are parked in a high density, thereby providing a safer parking environment.

[0066]

[0067] FIG. 3 illustrates an example of the structure of a parking plate and a partition wall of a parking structure according to an embodiment of the present invention.

[0068] A parking structure according to an embodiment of the present invention may be configured to include a parking plate (300) for accommodating a parked vehicle and a plurality of wing partitions (310) installed on the side or bottom surface of the parking plate. When there is no vehicle on the parking plate (300), the wing partitions (310) may be folded down below the parking plate (300) and maintained in a state of parallel with the plate (300).

[0069] Referring to FIG. 3, when a vehicle is parked on the parking plate (300) and the driver gets out and moves to the plate, the edge of the wing bulkhead (310) moves upward, so that the wing bulkhead (310) can form a simple water tank together with the parking plate (300).

[0070] The parking structure may also further include a control device (200) for controlling the movement of the wing bulkhead (310) and a fire extinguishing agent inlet (not shown) positioned on the side or bottom surface of the parking plate. In the event of a fire, the control device (200) may control the fire extinguishing agent inlet so that the fire extinguishing agent flows into the space (simple tank) formed by the plurality of wing bulkheads and the parking plate.

[0071] According to another embodiment, the control device (200) may control the movement of a plurality of wing bulkheads when it is determined that a fire has occurred in the vehicle, thereby moving and positioning the plurality of wing bulkheads so that the plurality of wing bulkheads surround the side of the parking plate.

[0072] Here, the control device (200) can detect the occurrence of a fire through one or more temperature sensors installed at a specific location within the parking frame. Preferably, the temperature sensors can be attached and installed near the ceiling of the parking frame.

[0073]

[0074] FIG. 4 illustrates the structure of a water tank of a parking structure according to an embodiment of the present invention.

[0075] The parking structure according to the embodiment of the present invention may further include a water tank disposed below the ground inside the parking tower (100).

[0076] The control device of the parking structure can, when it is determined that fire remains even after a certain period of time has elapsed after introducing a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate, control a valve connected to a damper supporting the parking plate as a secondary measure to drop the vehicle into the water tank (400).

[0077] Here, the tank (400) is formed to a size capable of accommodating a vehicle and can be maintained and managed in a state where it is filled with coolant / fire extinguishing liquid above a certain height under normal circumstances. The tank (400) can be installed in a buried form beneath the entrance / exit road where the vehicle enters and exits.

[0078]

[0079] FIG. 5 illustrates an example of a damper and valve structure of a parking structure according to an embodiment of the present invention.

[0080] A parking structure according to an embodiment of the present invention may include a parking plate (300) for accommodating a parked vehicle, a plurality of dampers (510; 520) for supporting the parking plate, a valve (700) for controlling the expansion and contraction of the dampers, and a control device (200).

[0081] The control device (200) can change the shape of the damper by controlling the valve (700).

[0082] More specifically, the plurality of dampers may include a first damper (510) that supports a part of the parking plate (300) and a second damper (520) that supports a part of the parking plate (300).

[0083] Here, the first damper (510) and the second damper (520) may be connected to the valve (700) through an air inlet / outlet passage (710). The air inlet / outlet passage (710) may be provided in the form of a hose. The first damper (510) and the second damper (510) are connected to the air inlet / outlet passage (710) with the valve (700) in the middle, so that when the valve (700) is opened, air inside the first damper (510) may move to the second damper (520) through the air inlet / outlet passage (710) due to the pressure difference between the first damper (510) and the second damper (520), and air inside the second damper (520) may move to the first damper (510) through the air inlet / outlet passage (710).

[0084] Referring to FIG. 5, in a normal situation where no fire occurs, the valve (700) is kept in a closed state. Additionally, the first damper (510) is kept in a maximum compressed state and the second damper (520) is kept in a maximum expanded state, so that the parking plate (300) can be supported in a balanced state. Of course, the first damper (5100) can be kept in a maximum expanded state and the second damper (520) can be kept in a maximum compressed state, so that the parking plate (300) can be supported in a balanced state.

[0085] Meanwhile, the control device (200) can control the valve (700) to an open state in the event of a fire (for example, as a secondary measure when an attempt to extinguish the fire through the bulkhead of the parking plate and the inflow of a fire extinguishing agent fails), thereby releasing the expansion state of the second damper (520) through the air inlet / outlet passage and switching the parking plate to a non-equilibrium state. When the parking plate becomes non-equilibrium, that is, tilted, the vehicle supported by the parking plate falls down and is drawn into the water tank of the structure shown in FIG. 4.

[0086] Meanwhile, the first damper (510) and the second damper (520) are connected to the fixed shaft (600) through supports (601, 602) and can be provided in a form that allows them to move up and down due to the weight of the vehicle applied to the parking plate (300). In this structure, air escaping from the second damper (520) is applied to the first damper (510) through the air inlet / outlet passage (710), and the resulting expansion of the first damper (510) can accelerate the tilting speed of the parking plate (300). Accordingly, the time it takes for the vehicle to enter the water tank is shortened.

[0087]

[0088] FIG. 6 illustrates another example of a damper and valve structure of a parking structure according to an embodiment of the present invention.

[0089] A parking structure according to an embodiment of the present invention illustrated in FIG. 6 may also include a parking plate (300) for accommodating a parked vehicle, a plurality of dampers (510, 520) supporting the parking plate, and a valve (700) for controlling the expansion and contraction of the dampers.

[0090] More specifically, the plurality of dampers may include a first damper (510) that supports a part of the parking plate (300) and a second damper (520) that supports a part of the parking plate (300). Here, the first damper (510) and the second damper (520) may be connected to a valve (700) through an air inlet / outlet passage (710).

[0091] Under normal conditions where no fire occurs, the valve is maintained in a closed state. Additionally, the first damper (510) is maintained in a maximum compressed state and the second damper (520) is maintained in a maximum expanded state, thereby supporting the parking plate in a balanced state. Of course, the first damper (510) may be maintained in a maximum expanded state and the second damper (520) in a maximum compressed state, thereby supporting the parking plate in a balanced state.

[0092] Referring to FIG. 6, in this embodiment, a valve (700) that automatically changes to an open state due to high temperature can be mounted on the upper part of the space where a vehicle is parked, taking into account situations such as when the fire detection system inside the parking tower is abnormal. When the valve (700) is opened due to high temperature caused by fire, etc., the air inside the second damper (520) escapes through the air inlet / outlet passage (710), and the second damper (520) is compressed. The air escaping from the second damper (520) induces the expansion of the first damper (510) through the air inlet / outlet passage (710), thereby increasing the tilting speed of the parking plate, and accordingly, shortening the time for the vehicle supported by the parking plate to fall downward and enter the water tank of the structure examined through FIG. 4.

[0093] In the embodiment illustrated in FIG. 6, unlike the embodiment of FIG. 5, a separate control device is not required, and the structure of the embodiment is provided in a form that can be changed by high temperatures caused by fire.

[0094]

[0095] FIG. 7 shows the sequence of operations of a method for controlling a parking structure according to an embodiment of the present invention.

[0096] A method for controlling a parking structure according to an embodiment of the present invention can be performed by a control device (200) of the parking structure.

[0097] Referring to FIG. 7, when a vehicle is parked on a parking plate and the driver exits and moves to the plate, the control device (200) controls the movement of a plurality of wing bulkheads so that the plurality of wing bulkheads are moved and positioned to surround the side of the parking plate (S710). Subsequently, if it is determined that a fire has occurred in the vehicle (e.g., S720), the control device (200) controls a fire extinguishing agent inlet so that a fire extinguishing agent is introduced into the space formed by the plurality of wing bulkheads and the parking plate (S730).

[0098] Meanwhile, according to another embodiment, the control device (200) may control the movement of a plurality of wing bulkheads after determining that a fire has occurred in the vehicle, thereby moving and positioning the plurality of wing bulkheads so that the plurality of wing bulkheads surround the side of the parking plate.

[0099] If the fire persists even after a certain period of time has elapsed after the extinguishing agent has been introduced (e.g., S740), as a secondary measure, the valve connected to the first damper (510) and the second damper (510) is controlled to an open state (S750), thereby releasing the expansion state of the second damper (520) through the air inlet / outlet passage and switching the parking plate to a non-equilibrium state. When the parking plate becomes non-equilibrium, that is, tilted, the vehicle supported by the parking plate falls downward and is drawn into the water tank of the structure shown in FIG. 4 (S751).

[0100] Meanwhile, in the embodiment of FIG. 7, the configuration of dropping a vehicle on a parking plate into a water tank by releasing the equilibrium state of the damper using a valve was described as a secondary measure after an attempt to extinguish a fire using a bulkhead. However, according to another embodiment of the present invention, the fire extinguishing procedure using a bulkhead may be omitted, and the procedure of dropping a vehicle on a parking plate into a water tank by releasing the equilibrium state of the damper using a valve may be performed independently.

[0101]

[0102] FIG. 8 is a block diagram of a parking structure control device according to an embodiment of the present invention.

[0103] A parking structure control device (200) according to an embodiment of the present invention may include one or more processors (210); and a memory (220) that stores at least one instruction executed through said processor.

[0104] The parking structure control device (200) can also be operated in connection with a plurality of wing bulkheads (310) installed on the side or bottom of the parking plate, a valve (700) that controls the expansion and contraction of a damper supporting the parking plate (300), and one or more temperature sensors (not shown) installed in a certain place within the parking frame.

[0105] Here, the parking structure may be configured to include a plurality of wing bulkheads installed on the side or bottom surface of a parking plate, a plurality of dampers supporting the parking plate, and a valve controlling the expansion and contraction of the dampers.

[0106] At least one command performed by the processor (210) of the above parking structure control device (200) may include a command to determine whether a fire occurs in a vehicle parked on the parking plate, and, when a fire occurs in the vehicle, to control the flow of a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate, or to control the shape of the damper to change.

[0107] According to one embodiment, a command to control the inflow of a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate, or to control the change in the shape of the damper, may include: a command to move and arrange the plurality of wing bulkheads so that the plurality of wing bulkheads surround the side of the parking plate; and a command to control the fire extinguishing agent inlet so that the fire extinguishing agent flows into the space formed by the plurality of wing bulkheads and the parking plate.

[0108] The command to control the introduction of a fire extinguishing agent into the space formed by the plurality of wing bulkheads and the parking plate, or to control the change in the shape of the damper, may also include a command to control the valve to drop the vehicle into a water tank placed below the ground if a fire remains after a certain period of time has elapsed after the fire extinguishing agent has been introduced into the space formed by the plurality of wing bulkheads and the parking plate.

[0109] According to another embodiment, the step of controlling one or more of the plurality of wing bulkheads and the valve may include a command to control the valve to an open state in the event of a fire to release the expansion state of the second damper through the air inlet / outlet passage and to switch the parking plate to a non-equilibrium state.

[0110] The parking structure control device (200) according to the present invention may also further include an input interface device (240), an output interface device (250), a storage device (260), etc. Each component included in the parking structure control device (200) may be connected by a bus (270) to communicate with each other.

[0111] Additionally, the memory (220) may be composed of at least one of a volatile storage medium and a non-volatile storage medium. For example, the memory may be composed of at least one of a read-only memory (ROM) and a random access memory (RAM), and may include an EEPROM (Electrically Erasable Programmable Read-only Memory).
