DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0052] Combined with reference Figure 1 and Figure 2 , Figure 1 This is a schematic axonometric diagram of the structure of a fire-fighting device provided in an embodiment of the present application. Figure 2 , which is a schematic front view of the structure of a fire-fighting device provided in an embodiment of the present application, the fire-fighting device includes: an isolation device 20, a controller (not shown in the figure), and a guide rail 40; the fire-fighting device is arranged on the side of the ceiling 10 of the parking space facing the parking space 30, the ceiling 10 is erected on the plane where the parking space 30 is located through support columns, and the projection of the ceiling 10 on the plane covers multiple parking spaces 30; the guide rail 40 is arranged on the side of the ceiling 10 facing the parking space 30, and the projection of the guide rail 40 on the plane at least partially overlaps with the parking space 30; the isolation device 20 is movably arranged on the guide rail 40; the controller is used to respond to the fire information for the target vehicle, control the isolation device 20 to move on the guide rail 40 to the position corresponding to the target parking space where the target vehicle is located, and control the isolation device 20 to isolate the target parking space from the outside world.

[0053] Combined with reference Figure 1 and Figure 2 In the embodiment of the present application, a first parking space 31 and a second parking space 32 are arranged along the X direction. In the fire-fighting device provided in the embodiment of the present application, the projection of the ceiling 10 on the plane where the parking space 30 is located covers the first parking space 31 and the second parking space 32. On the side of the ceiling facing the parking space 30, a guide rail 40 is laid along the X direction so that the projection of the guide rail 40 on the plane where the parking space 30 is located overlaps with the parking space 30. The isolation device 20 is arranged on the guide rail 40 and can be moved along the direction X of the guide rail. If a fire occurs in the first parking space 31, the controller will respond to the fire information of the first parking space 31, control the isolation device 20 to move on 40 to the position corresponding to the first parking space 31, and control the isolation device 20 to isolate the first parking space 31 from the outside.

[0054] In an embodiment of the present application, after a fire occurs, the controller can determine the target parking space where the fire occurs through the fire information, and move the isolation device to the position corresponding to the target parking space on the guide rail, and isolate the target parking space where the fire occurs through the isolation device; the isolation device blocks the target parking space from contact with the external environment, isolates the fire source from the air or other combustibles, prevents the spread of fire, plays the role of fire extinguishing, reduces fire damage, and minimizes economic losses; the design of the movable isolation device enables the isolation device to be accurately moved to the target parking space where the fire occurs in a short time for isolation operations, and there is no need to set up an isolation device for each parking space. While achieving rapid response and rapid processing to the fire, it saves production and maintenance costs and improves economic benefits.

[0055] Optional, reference Figure 2The isolation device 20 includes: a fireproof rolling curtain 22, a rolling curtain motor (not shown), and a moving device 21; when the fireproof rolling curtain 22 isolates the parking space 30, it forms a cavity structure with one end open, and the opening of the fireproof rolling curtain 22 faces the parking space 30, and the size of the opening is larger than the size of the parking space 30; the other end of the fireproof rolling curtain 22 is connected to the moving device 21; the moving device is movably arranged on the guide rail 40; the moving device is used to drive the fireproof rolling curtain 22 to move on the guide rail 40 under the control of the controller; When the curtain 22 moves to the position corresponding to the target parking space, under the drive of the roller shutter motor, one end of the opening of the fireproof roller shutter 22 moves toward the target parking space, so that the cavity structure covers the target parking space and the target vehicle in the target parking space, thereby isolating the target parking space and the target vehicle from the outside world; or, after the isolation of the target parking space and the target vehicle from the outside world is completed, under the reverse drive of the roller shutter motor, one end of the opening of the fireproof roller shutter 22 moves toward the direction close to the moving device 21, and the fireproof roller shutter 22 is folded and set on the moving device 21.

[0056] Combined with reference Figure 1 and Figure 2 In the fire-fighting device provided in the embodiment of the present application, the main structure of the isolation device 20 may include: a fireproof rolling curtain 22, a rolling curtain motor, and a moving device; if the controller determines that the target parking space where the fire occurs is the first parking space 31, the controller will further drive the moving device 21 to move, and the moving device 21 is connected to the guide rail 40 and can reach the position corresponding to the first parking space 31 along the X direction under the drive of the controller. Since the fireproof rolling curtain 22 is fixedly connected to the moving device 21, the fireproof rolling curtain 22 also reaches the position corresponding to the first parking space 31; before receiving the relevant instructions of the controller, the fireproof rolling curtain 22 is folded and set on the moving device 21; further reference Figure 3 ,for Figure 2In the cross-sectional view along AA, the fireproof roller shutter 22 is a cavity structure with one end open. When the mobile device 21 moves to the position corresponding to the first parking space 31, the controller issues relevant instructions to make the roller shutter motor drive the open end of the fireproof roller shutter 22 to move toward the first parking space 31, even if the fireproof roller shutter 22 extends along the Y1 direction, so that the cavity structure covers the first parking space 31 and isolates the first parking space 31 from the outside. When the fire in the first parking space 31 is extinguished and the relevant firefighting operations are completed, the controller can issue relevant instructions to make the roller shutter motor reverse and drive the open end of the fireproof roller shutter 22 to move in the direction close to the mobile device 21, even if the fireproof roller shutter 22 shrinks along the Y2 direction, so that the fireproof roller shutter 22 is refolded and set on the mobile device 21, so as to avoid the fireproof roller shutter 22 interfering with the subsequent operations of the first parking space 31, and at the same time facilitate the fireproof roller shutter 22 to move to other positions of the guide rail 40 for operation. The isolation device 20 can be quickly transferred on the guide rail 40, and the fireproof roller shutter 22 can complete the fire response in a short time under the drive of the roller shutter motor, effectively separating the area where the fire occurs from other areas, isolating the fire source from the outside air and combustibles to a certain extent, and preventing the fire from spreading to other areas.

[0057] Furthermore, the fireproof roller shutter can be made of high temperature resistant inorganic materials, such as glass fiber, which has excellent fire resistance and can block fire and high temperature in a fire.

[0058] Optional, reference Figure 3 The fire fighting device further includes: a monitor 50; the monitor 50 is arranged on a side of the ceiling 10 facing the parking space; the monitor 50 is used to obtain fire information and send the fire information to the controller.

[0059] In the fire-fighting device provided in the embodiment of the present application, the controller can obtain fire information through a monitor 50 set on the ceiling 10; in embodiments not shown in the present application, the monitoring device can also be set at other locations where parking space fire information can be monitored, such as setting the monitor on a charging pile corresponding to the parking space.

[0060] Optionally, the monitor 50 includes a smoke sensor and a fire camera; the smoke sensor is arranged on the side of the ceiling 10 facing the parking space, and the setting position of the smoke sensor corresponds one-to-one to the position of the parking space; the fire camera is arranged on the side of the ceiling 10 facing the parking space; the fire information includes smoke information and image information; the smoke sensor is used to obtain smoke information and send the smoke information to the controller; the fire camera is used to obtain image information and send the image information to the controller; the controller is also used to determine the occurrence of a fire when the smoke information indicates that the smoke concentration is greater than a set threshold, and or when the image information indicates the existence of a fire image; the controller is also used to determine the location of the target parking space where the fire occurs by integrating the smoke information and image information.

[0061] The fire information obtained by the monitor 50 may include image information and smoke information. The image information may be obtained through a fire camera, and the smoke information may be obtained through a smoke sensor. The fire camera and the smoke sensor may be arranged on the side of the ceiling 10 facing the parking space, so that after a fire occurs in a target vehicle in the parking space, the monitor 50 may obtain the fire information in the first time; the image information may include a fire image, and the smoke information may include a smoke concentration. After the controller receives the image information, the image information may be analyzed. When there is a fire image in the image information, the controller will determine that a fire has occurred. After the controller receives the smoke information, the smoke information may be analyzed. When the smoke concentration is greater than a set threshold, the controller will also determine that a fire has occurred. The set threshold represents the maximum smoke concentration when no fire has occurred. The judgment logic for determining the occurrence of a fire through image information and the judgment logic for determining the occurrence of a fire through smoke information are in an "and or" relationship, so as to ensure that the monitor can still maintain normal operation when one of the fire camera and the smoke sensor fails to work properly.

[0062] After confirming that a fire has occurred, the controller will comprehensively analyze the smoke information and image information to determine the target parking space where the fire has occurred. For example, in some fire scenarios, the smoke generated by the fire will spread, causing multiple smoke sensors to send smoke information to the controller indicating that the smoke concentration is greater than the set threshold. At this time, it is difficult to determine the target parking space where the fire has occurred only through the smoke information; in other fire scenarios, the fire camera may be blocked by debris, resulting in the image information sent by the fire camera to the controller not containing the fire image when the fire occurs. At this time, it is difficult to determine the target parking space where the fire has occurred only through the image information; by comprehensively analyzing the smoke information and image information, the controller can determine the location of the target parking space where the fire has occurred, so that the isolation device can accurately reach the target parking space to perform isolation and firefighting operations.

[0063] Optionally, the controller is also used to respond to fire information about the target parking space, cut off the power supply of the charging device 60 corresponding to the target parking space, and send a linkage signal to the cloud server; the cloud server is used to send a fire alarm signal to the target device when receiving the linkage signal.

[0064] The controller can control the isolation device, and can also control the electrical equipment supporting the parking space, for example, the charging device corresponding to the parking space; after receiving the fire information, the controller can cut off the power supply of the charging device corresponding to the target parking space, realize the linkage response of the isolation fire fighting operation of the isolation device and the charging facilities, avoid secondary safety accidents caused by leakage, and reduce the waste of electrical energy; Reference Figure 2In the fire-fighting device provided in the embodiment of the present application, if a fire occurs in the target vehicle on the first parking space 31, the controller can cut off the power supply of the first charging device 61 to prevent leakage after the fire damages the first charging device 61; if the first charging device 61 is connected to the circuit of the second charging device 62 corresponding to the second parking space 32, the controller can also cut off the power supply of the first charging device 61 and the second charging device 62 at the same time to prevent short circuit and leakage.

[0065] The controller can also be connected to the cloud server for communication. After receiving the fire information of the target parking space, the controller sends a linkage signal to the cloud server. After receiving the linkage signal, the cloud server sends a fire alarm signal to the target device. The target device may include the devices of relevant personnel, for example, the communication device of the owner of the target vehicle in the target parking space where the fire occurs, the communication device of the staff of the facility where the parking space is located, the communication device of the owner of the vehicle in the parking space adjacent to the target vehicle, the communication device of the firefighters, etc. The fire alarm signal may include text messages, phone calls, push notifications and other messages that can be understood by relevant personnel. By sending a fire alarm signal to the target device, relevant personnel can be notified to intervene in the fire. For unmanned self-service charging stations, garages and other facilities, rapid manual intervention can minimize the property losses caused by the spread of fire.

[0066] Optionally, the fire-fighting device also includes an audible and visual alarm; the controller is also used to respond to the fire information of the target parking space and control the audible and visual alarm to sound an alarm.

[0067] The controller can also respond to fire information of the target parking space and sound an alarm through an audible and visual alarm; the audible and visual alarm may include alarm bells, warning lights, sirens and other equipment; the audible and visual alarm can quickly warn on-site personnel, allowing them to respond quickly to the fire, conduct manual intervention, and nip the fire in the bud.

[0068] Optional, reference Figure 2 The mobile device 21 also includes: a rolling shutter container 211, a fixed cover of the rolling shutter container 211 is arranged on the main body of the mobile device 21, and the inner wall size of the rolling shutter container 211 is larger than the size of the fireproof rolling shutter 22 when the fireproof rolling shutter 22 is folded and arranged on the mobile device 21; the rolling shutter container 211 is used to store the fireproof rolling shutter 22 when the fireproof rolling shutter 22 is folded and arranged on the mobile device 21.

[0069] A roller shutter container 211 is fixedly mounted on the main body of the mobile device 21 for storing the folded fireproof roller shutter 22 to prevent the fireproof roller shutter 22 from failing or being damaged due to the external environment. The roller shutter container 211 can not only allow the folded fireproof roller shutter 22 to be regularly folded and stored inside the roller shutter container 211 to prevent the folded roller shutter 22 from interfering with other components of the fire-fighting device 20, but also prevent external debris from entering the folded fireproof roller shutter 22 when the fireproof roller shutter 22 is folded to prevent the fireproof roller shutter 22 from being unable to operate normally.

[0070] Optionally, the isolation device further comprises an electromagnetic lock, which is arranged on the mobile device; the electromagnetic lock is used to keep the fireproof roller curtain in a locked state when the fireproof roller curtain is folded and arranged on the mobile device.

[0071] When the fireproof rolling curtain is folded and arranged on the mobile device, the fireproof rolling curtain can be kept locked by an electromagnetic lock arranged on the mobile device to prevent the fireproof rolling curtain from falling from the mobile device due to gravity;

[0072] Furthermore, when the shutter motor fails, the fire shutter can be released through the electromagnetic lock when the fire shutter moves to the corresponding position of the target parking space where the fire occurs. Under the action of gravity, the fire shutter will fall to cover the target parking space and the target vehicle in the target parking space, thereby isolating the target parking space and the target vehicle from the outside world.

[0073] Optionally, the fire camera includes a first camera, which is arranged on a side of the ceiling facing the parking space. Multiple first cameras are arranged on each ceiling, and the setting positions of the first cameras correspond one-to-one to the positions of the parking spaces; the image information includes image information on the corresponding parking space obtained by each first camera.

[0074] In the fire-fighting device provided in the embodiment of the present application, an optional implementation method of the fire-fighting camera in the monitor is to install a first camera for each parking space. The setting position of the first camera corresponds one-to-one to the position of the parking space, and the first camera can be used to obtain image information on the corresponding parking space; the first camera can adopt a conventional camera, and its shooting angle of view is within 180°, and can adopt a focal length of 2.8mm, 4.6mm, etc. Due to the small shooting angle of view, it is suitable for one-to-one use with the parking space; accordingly, the image information includes the image information of the corresponding parking space obtained by each first camera, and the controller can select the image information of the fire from the multiple image information, and further analyze to obtain the position of the target parking space of the target vehicle where the fire occurs.

[0075] Optionally, the fire camera includes a second camera, which is arranged on a side of the ceiling facing the parking spaces, and a second camera is arranged on each ceiling. The image information includes images of all corresponding parking spaces acquired by the second camera.

[0076] In the fire-fighting device provided in the embodiment of the present application, another optional implementation method of the fire-fighting camera in the monitor is to use a second camera that can simultaneously obtain image information of multiple parking spaces; for example: a second camera is set for each ceiling, and one second camera can correspond to all parking spaces in a ceiling; or, a second camera is set for all ceilings, and one second camera corresponds to all parking spaces corresponding to all ceilings; the second camera can use a panoramic camera, and its shooting angle can reach 360°, which can independently realize a large range of shooting without dead angles, and can use an ultra-short focal length of 1.6mm, which is suitable for one-to-many simultaneous monitoring of multiple parking spaces; accordingly, the image information includes the image information of all corresponding parking spaces obtained by the second camera, and the controller can analyze the location of the target parking space where the fire occurs from the image information of all corresponding parking spaces according to the pre-division of parking spaces. It should be noted that this implementation method needs to ensure that the second camera can monitor all parking spaces.

[0077] Optional, combined with reference Figure 2 and Figure 3 The fireproof rolling shutter 22 includes: four side panels 221 and a top panel 222; the four side panels 221 are respectively arranged on the four edges of the top panel 222, and the top panel 222 is fixedly arranged in the rolling shutter container 211; each side panel 221 includes a plurality of isolation sheets 2211 which are arranged in sequence in a direction Y1 away from the top panel, and the plurality of isolation sheets 2211 can be folded and stored in the rolling shutter container 211, or the plurality of isolation sheets 2211 can extend from the rolling shutter container 211 to form a plate-like structure.

[0078] In the fire-fighting device provided in the embodiment of the present application, an optional implementation of the fireproof roller shutter 22 is a foldable isolation sheet 2211, and the isolation sheet 2211 forms a side panel 221 after extending out of the roller shutter container 211, and the side panel 221 and the top panel 222 constitute a cavity structure; the isolation sheet 2211 can be contracted along the Y2 direction and folded and stored in the roller shutter container 211, saving space and facilitating the movement of the roller shutter container 211 on the guide rail 40; if the target vehicle where the fire occurs is located in the first parking space 31, the isolation sheet 2211 extends out from the roller shutter container 211 and descends along the Y1 direction to contact the first parking space 31, thereby isolating the first parking space 31 from the outside world.

[0079] For further reference, Figure 1 A groove 311 may be provided around each parking space, and the size and shape of the groove 311 are adapted to the shape and size of one end of the opening of the fireproof rolling curtain 22; if the target vehicle where the fire occurs is located in the first parking space 31, then when one end of the opening of the fireproof rolling curtain 22 moves toward the first parking space 31, it may be inserted into the groove 311, thereby increasing the stability of the fireproof rolling curtain 22 and enhancing the sealing of the fireproof rolling curtain 22, so that the isolation device 20 can achieve a better isolation effect.

[0080] refer to Figure 4 , which is a communication diagram of the fire-fighting device provided in the embodiment of the present application, characterizes the communication relationship between the various components and equipment in the fire-fighting device. The controller receives the image information from the fire-fighting camera and the smoke information from the smoke sensor.

[0081] In the embodiment of the present application, after a fire occurs, the controller can determine the target parking space where the target vehicle on fire is located through the fire information, and move the isolation device to the position corresponding to the target parking space on the guide rail, and isolate the target vehicle on fire and the target parking space where it is parked through the isolation device; the isolation device blocks the target parking space from contact with the external environment, isolates the fire source from the air or other combustibles, prevents the fire from spreading, and achieves the effect of fire extinguishing; the design of the movable isolation device enables the isolation device to be accurately moved to the target parking space where the fire occurs in a short time for isolation operation, and there is no need to set up an isolation device for each parking space; the fire camera and The setting of the smoke sensor ensures that the fire information can be smoothly acquired and sent to the controller for analysis, so that the controller can determine the occurrence of fire and the target parking space, and further enables the isolation device to quickly and accurately complete the isolation fire fighting operation; through the communication connection with the cloud server and the sound and light alarm, the alarm notification is achieved to the relevant personnel, ensuring the rapid response of manual intervention; in addition, the controller can also control the electrical equipment matched with the parking space, and cut off the power immediately to avoid electrical leakage and waste of electricity; in general, the fire fighting device provided by the embodiment of the present application can achieve rapid response to the fire and rapid processing while saving production and maintenance costs and improving economic benefits.

[0082] In a second aspect, the embodiment of the present application provides a fire control method, which is applied to the fire fighting device as described in the first aspect, referring to Figure 5 , is a flowchart of the steps of the fire control method provided in an embodiment of the present application, the method comprising:

[0083] Step 101: Obtain fire information through a monitor and send it to a controller.

[0084] First, the fire information is monitored through the monitor, including obtaining image information through the fire camera and sending it to the controller, and obtaining smoke information through the smoke sensor and sending it to the controller; through the monitor, relevant fire information can be obtained as soon as a fire occurs.

[0085] Step 102: The controller confirms the occurrence of a fire when the fire information satisfies a preset condition, and at the same time confirms the location of the target parking space where the fire occurs based on the fire information.

[0086] After receiving the fire information, the controller analyzes the fire information; after receiving the image information, the controller can analyze the image information. When there is a fire image in the image information, the controller will determine that a fire has occurred; and or, after receiving the smoke information, the controller can analyze the smoke information. When the smoke concentration is greater than a set threshold, the controller will determine that a fire has occurred. The set threshold represents the maximum smoke concentration when no fire occurs.

[0087] After determining that a fire has occurred, the controller will comprehensively analyze the smoke information and the image information to determine the target parking space where the fire has occurred. The controller may also determine the target parking space where the fire has occurred through smoke information alone or image information alone.

[0088] Step 103: Control the isolation device to move to a corresponding position of the target parking space on the guide rail through a controller.

[0089] Step 104: Control the isolation device through the controller to lower the fireproof roller shutter to isolate the target parking space from the outside world.

[0090] Step 103-Step 104 illustrate how the controller controls other components of the fire-fighting device to perform isolation fire-fighting operations after determining the target parking space. Specifically, the roller shutter container of the isolation device is first moved to the position corresponding to the target parking space on the guide rail by the moving device on the isolation device, and then the roller shutter motor of the isolation device lowers the fire-proof roller shutter stored in the roller shutter container, and the fire-proof roller shutter is lowered to cover the target parking space, completing the isolation of the target parking space from the outside world and achieving the purpose of fire-fighting.

[0091] Optionally, after step 102, the method further includes:

[0092] Step S1, controlling the sound and light alarm to sound an alarm through the controller.

[0093] The sound and light alarm can quickly warn on-site personnel, allowing them to respond quickly to the fire, perform manual intervention, and nip the fire in the bud.

[0094] Step S2: Cut off the power supply of the charging device corresponding to the target parking space through the controller.

[0095] The controller can be used to control electrical equipment associated with the parking space, for example, the charging device corresponding to the parking space; after receiving fire information, the controller can cut off the power supply of the charging device corresponding to the target parking space, realize the isolation fire-fighting operation of the isolation device and the linkage response of the charging facilities, avoid secondary safety accidents caused by leakage, and reduce the waste of electrical energy.

[0096] Step S3: Send a linkage signal to the cloud server through the controller. When the cloud server receives the linkage signal, it sends a fire alarm signal to the target device.

[0097] The controller can also communicate with the cloud server. After receiving the fire information of the target vehicle, it sends a linkage signal to the cloud server. After receiving the linkage signal, the cloud server sends a fire alarm signal to the target device. The target device may include the communication equipment of relevant personnel. By sending a fire alarm signal to the target device, relevant personnel can be notified to intervene in the fire. For unmanned self-service charging stations, garages and other facilities, rapid manual intervention can minimize the property losses caused by the spread of fire.

[0098] Steps S1 to S3 illustrate the auxiliary firefighting operations performed by the controller after confirming the occurrence of a fire, including controlling the sound and light alarm to sound an alarm; sending a linkage signal to the cloud server, and the cloud server sends a fire alarm signal to the target device when receiving the linkage signal; and cutting off the power supply of the charging device corresponding to the target parking space. Among them, steps S1 and S3 notify the personnel related to the fire to perform manual intervention through different alarm methods to extinguish the fire as soon as possible, avoid the spread of the fire, and avoid further economic losses. Step S2 is to control the electrical equipment related to the target parking space to avoid secondary accidents and reduce the waste of electrical energy. It should be noted that the embodiment of the present application only limits steps S1, S2, and S3 to be executed after step 102, and the order between steps S1, S2, and S3 is not limited. For example, step S2 can be executed after step S1, or step S1 can be executed after step S2.

[0099] In the embodiment of the present application, after a fire occurs, the controller can determine the target parking space where the target vehicle where the fire occurs is located through the fire information, and move the isolation device to the position corresponding to the target parking space on the guide rail, and isolate the target vehicle where the fire occurs and the target parking space where it is parked through the isolation device; the isolation device blocks the target parking space from contact with the external environment, isolates the fire source from the air or other combustibles, prevents the spread of fire, and achieves the effect of fire extinguishing; by controlling the movement of the isolation device on the guide rail, the isolation device can be accurately moved to the target parking space where the fire occurs in a short time for isolation operation, and there is no need to set up an isolation device for each parking space; by alerting relevant personnel, manual intervention in the fire is achieved; by controlling the supporting electrical equipment, waste of electrical resources and secondary safety accidents are avoided; in general, the fire control method provided in the embodiment of the present application can save production and maintenance costs and improve economic benefits while achieving rapid response and rapid processing to fires.
