Description

Technical Field

[0001] This disclosure relates to battery storage safety technology, and in particular to a fire suppression device, system, and method. Background Technology

[0002] In battery storage scenarios, such as lithium battery storage and electric vehicle parking, fire suppression systems are typically required to ensure battery storage safety due to the potential for overheating and runaway. Related technologies usually involve smoke detectors to detect fires, triggering a full-area sprinkler system to extinguish the fire in the battery storage area upon detection. However, smoke detectors are prone to false alarms, leading to unnecessary asset losses. Summary of the Invention

[0004] A first aspect of this disclosure provides a fire suppression device, comprising: a sensor configured to collect sensor data of a preset area; the preset area including at least one sub-area; a smart identifier connected to the sensor, the smart identifier being configured to identify, based on the sensor data, whether a fire has occurred in each of the sub-areas of the preset area; at least one sprinkler head and at least one corresponding zone control valve, each zone control valve corresponding to a sub-area; each sprinkler head being connected to a fire extinguishing agent bottle via a delivery pipeline; and a controller connected to the smart identifier and the zone control valve, the controller being configured to, when the smart identifier identifies a fire in a target sub-area of ​​the preset area, control the zone control valve corresponding to the target sub-area to open, thereby controlling the sprinkler head corresponding to the target sub-area to spray fire extinguishing agent.

[0005] A second aspect of this disclosure provides a fire suppression system, comprising: a fire suppression device provided in any of the above embodiments; and a server connected to the fire suppression device for remotely controlling the fire suppression device.

[0006] A third aspect of this disclosure provides a fire suppression method, comprising: installing a sensor above a preset area such that the sensor's sensing range covers the preset area; the preset area includes at least one sub-area; installing at least one sprinkler head and a corresponding zone control valve above each sub-area; each zone control valve corresponding to a sub-area; each sprinkler head being connected to a fire extinguishing agent bottle via a delivery pipeline; installing a smart identifier at a designated location above the preset area, the smart identifier being connected to the sensor; installing a controller at a designated location in the preset area; continuously monitoring whether a fire occurs in each sub-area of ​​the preset area using the sensor and the smart identifier; and, when the smart identifier detects a fire in a target sub-area of ​​the preset area, controlling the zone control valve corresponding to the target sub-area to open via the controller, thereby controlling the sprinkler head corresponding to the target sub-area to spray fire extinguishing agent.

[0007] Based on the fire suppression device, system, and method provided in the above embodiments of this disclosure, since the intelligent identifier can accurately identify whether a fire has occurred in each sub-area of ​​the preset area S, and can individually control the spraying of agents by the corresponding nozzles of the sub-area, the precise location and suppression of the fire can be achieved, thereby avoiding or reducing false alarms. Furthermore, in the event of a fire in any sub-area, the spraying of extinguishing agents in other sub-areas outside the sub-area where the fire has occurred can be avoided, thereby preventing damage to assets in other sub-areas and effectively reducing asset losses.

[0027] This disclosure outlines

[0028] In the process of developing this disclosure, the inventors discovered that in related technologies for lithium battery storage scenarios and electric vehicle parking scenarios, fires are typically detected using smoke detectors, which then trigger a full-area sprinkler system to extinguish the fire in the battery storage area. However, smoke detectors are prone to false alarms. If a false alarm triggers a full-area sprinkler system to extinguish the fire, it can easily damage the batteries, electric vehicles, and other assets within the scenario, leading to unnecessary asset losses.

[0029] Exemplary Overview

[0030] Figure 1 This is an exemplary application scenario of the fire suppression device provided in the embodiments of this disclosure. For example... Figure 1As shown, the fire suppression device of this embodiment may include a sensor 11, a smart identifier 12, at least one sprinkler head 13 and at least one corresponding zone control valve 14, and a controller 15. The preset area S may be a battery storage area, an electric vehicle parking area, etc. The preset area S includes at least one sub-area; the figure shows four sub-areas as an example. In actual applications, the number of sub-areas and the size of each sub-area can be set according to the actual scenario requirements, and this embodiment is not limited thereto. Batteries or electric vehicles can be stored in the sub-areas. A sensor 11 capable of covering the preset area is provided above the preset area S. The sensor 11 may include, for example, a camera, or other types of sensors, such as smoke detectors, heat detectors, infrared detectors, etc., and is not specifically limited. The location and number of sensors 11 can be determined according to the actual scenario and are not limited to the location and number shown in the figure. Sensor data within the preset area S can be collected through the sensor 11, such as images (or videos) of the preset area S. The sensor 11 is connected to the smart identifier 12, which can identify whether a fire has occurred in each sub-area of ​​the preset area S based on the sensor data. The specific connection relationship between sensor 11 and smart identifier 12 is not limited to the relationship shown in the figure. For example, smart identifier 12 can be connected to one or more sensors via wired or wireless means. At least one nozzle 13 and at least one corresponding zone control valve 14 are provided above the preset area S. Each zone control valve 14 corresponds to a sub-area. In practical applications, one or more nozzles can be provided for each sub-area, which is not limited in this embodiment. When smart identifier 12 detects a fire in a sub-area (referred to as the target sub-area) of the preset area S, smart identifier 12 can communicate with controller 15. Controller 15 can control the zone control valve 14 corresponding to the target sub-area to open, so that the nozzle 13 above the target sub-area sprays fire extinguishing agent. Each nozzle 13 is connected to a fire extinguishing agent bottle 17 via a delivery pipeline 16. After the zone control valve 14 corresponding to the target sub-area is opened, the fire extinguishing agent in the fire extinguishing agent bottle 17 is delivered to the nozzle 13 corresponding to the target sub-area through the delivery pipeline 16. The nozzle 13 then sprays the fire extinguishing agent onto the target sub-area to suppress the fire. Because it can accurately identify whether a fire has occurred in each sub-area of ​​the preset area S, and can individually control the nozzles corresponding to each sub-area to spray the agent, it can achieve precise fire location and suppression, avoid or reduce false alarms, and prevent the spraying of fire extinguishing agents in other sub-areas besides the sub-area where a fire has occurred, effectively reducing asset losses.

[0031] Exemplary device

[0032] Figure 2 This is a schematic diagram of the structure of a fire suppression device provided in an exemplary embodiment of this disclosure. Figure 2 As shown, the fire suppression device (hereinafter referred to as the device) 10 provided in the embodiments of this disclosure may include: a sensor 11, a smart identifier 12, at least one sprinkler head 13 and at least one corresponding zone control valve 14, and a controller 15.

[0033] Sensor 11 is configured to collect sensor data from a preset area; the preset area includes at least one sub-area.

[0034] The intelligent identifier 12 is connected to the sensor 11 and is configured to identify whether a fire has occurred in each sub-area of ​​a preset area based on sensor data.

[0035] Each zone control valve 14 corresponds to a sub-zone; each nozzle 13 is connected to the extinguishing agent bottle through a delivery pipeline.

[0036] The controller 15 is connected to the smart identifier 12 and the zone control valve 14 respectively. The controller 15 is configured to: when the smart identifier 12 detects a fire in a target sub-area in the preset area, control the zone control valve 14 corresponding to the target sub-area to open, so as to control the nozzle 13 corresponding to the target sub-area to spray fire extinguishing agent.

[0037] In some optional embodiments, sensor 11 can be any sensor capable of detecting fire. For example, sensor 11 may include one or more of the following: a camera, a smoke detector, a heat detector, an infrared sensor, a photoelectric sensor, and a gas sensor. The specific sensor type and the number of each type of sensor can be set according to actual needs. For example, if sensor 11 includes a camera, the intelligent identifier 12 can identify whether a fire has occurred in each sub-area based on the images or videos (including one or more frames) captured by the camera and a pre-configured image-based fire identification model. The fire identification model is a pre-trained model. The network structure of the model can adopt any implementable structure, such as convolutional neural network models and their series of versions, recurrent neural network models and their series of versions, Transformer neural network models and their series of versions, etc. As another example, if sensor 11 includes a smoke detector, one or more smoke detectors can be set above each sub-area. The intelligent identifier 12 analyzes the smoke concentration distribution of each sub-area based on the data collected by the smoke detectors in each sub-area, and locates the target sub-area where a fire has occurred based on the smoke concentration distribution. Alternatively, the intelligent identifier 12 can determine the target sub-area where a fire has occurred based on whether the smoke detectors in each sub-area issue an alarm signal. For other types of sensors, corresponding identification algorithms and / or models that can accurately identify whether a fire has occurred in each sub-area can be configured on the intelligent identifier 12 according to their respective sensing characteristics; details will not be elaborated further.

[0038] In some optional embodiments, when sensor 11 includes multiple types of sensors, the intelligent identifier 12 can identify whether a fire has occurred in each sub-area using a multimodal fire identification model. That is, the fire identification model's input supports multiple types of sensor data, and the model integrates these data to identify whether a fire has occurred in each sub-area. Since the multimodal sensor data contains richer environmental feature information about the preset area, the accuracy of fire location can be further improved. It is understood that the multimodal fire identification model is pre-trained based on multimodal sensor data samples and annotation information.

[0039] In some optional embodiments, the number of sub-regions included in the preset area and the size of each sub-region can be set according to the actual needs of the scenario, and this disclosure does not limit them. For example, if n battery trays (hereinafter referred to as trays) are provided in a battery storage area, and each battery tray can store one or more batteries, then the area corresponding to each battery tray can be regarded as a sub-region. As another example, in an electric vehicle storage area, the storage area can be divided into multiple sub-regions according to the size of the storage area.

[0040] In some optional embodiments, the intelligent identifier 12 can be a packaged intelligent box (or AI-Box), a chip, or other form of product. The intelligent identifier 12 can implement the corresponding fire identification function through any of the following methods: hardware, software, or hardware + software. For example, the intelligent identifier 12 may include a processor (Central Processing Unit, or CPU) and a memory, and may also include other related auxiliary devices (such as interfaces for connecting to the sensor 11, interfaces for connecting to the controller 15, etc.). The memory is used to store the fire identification algorithm model, and the processor can read the fire identification algorithm model from the memory to perform fire identification based on the input sensor data. As another example, the intelligent identifier 12 may include a CPU, a neural network processor, and a memory. The CPU accelerates the inference process of the fire identification algorithm model by scheduling the neural network processor, improving the real-time performance of fire identification. The specific implementation of the intelligent identifier 12 is not limited.

[0041] In some optional embodiments, the number of smart identifiers 12 can be set to one or more, depending on the size of the actual scene and the number of sensors supported by the smart identifier 12. For example, if the smart identifier 12 supports 4 cameras and the preset area of ​​the actual scene is large enough to require 8 cameras, then two smart identifiers 12 can be set in the preset area scene to achieve fire monitoring of each sub-area in the entire area.

[0042] In some optional embodiments, each sub-region may correspond to at least one nozzle 13. Each sub-region may correspond to at least one zone control valve 14. If a sub-region contains multiple nozzles 13, the sub-region may include one or more zone control valves 14. For example, if a branch of the delivery pipeline of a sub-region is equipped with multiple nozzles 13 without affecting other sub-regions, a zone control valve can be installed on the branch of the delivery pipeline of that sub-region to control the multiple nozzles of that sub-region to spray extinguishing agent simultaneously. If the nozzles 13 of this sub-region share a delivery pipeline with nozzles 13 of other sub-regions, a corresponding zone control valve 14 can be installed for each nozzle 13. The control method for the nozzles in a specific sub-region is not limited.

[0043] In some alternative embodiments, the nozzle can be of any type. The zone control valve can be any implementable control valve, and this disclosure does not limit the specific implementation.

[0044] In some alternative embodiments, the controller 15 can be implemented in any feasible manner. For example, the controller 15 can be implemented using a microcontroller, an FPGA (Field Programmable Gate Array) chip, etc., and the embodiments disclosed herein are not limited thereto.

[0045] In some alternative embodiments, the controller 15 may be connected to the partition control valve 14 of each sub-region separately, so as to independently control the opening and closing of the partition control valve 14 of each sub-region.

[0046] In some optional embodiments, the target sub-region within the preset area can be any sub-region within the preset area. The target sub-region may include one or more sub-regions, specifically determined based on the identified sub-region where a fire has occurred. When the smart identifier 12 detects a fire in the target sub-region, it can send a fire signal related to the target sub-region to the controller 15 to notify the controller 15 to control the nozzles 13 in the target sub-region to spray extinguishing agent.

[0047] The fire suppression device provided in the embodiments of this disclosure can accurately identify whether a fire has occurred in each sub-area of ​​the preset area S through an intelligent identifier, and can individually control the nozzles corresponding to the sub-area to spray extinguishing agents. This can achieve accurate location and suppression of the fire, thereby avoiding or reducing false alarms. Furthermore, in the event of a fire in any sub-area, it can prevent the spraying of extinguishing agents in other sub-areas outside the sub-area where the fire has occurred, thereby avoiding damage to assets in other sub-areas and effectively reducing asset losses.

[0048] In some alternative embodiments, sensor 11 may include a camera, and at least one of a smoke detector, a temperature detector, an infrared sensor, a photoelectric sensor, and a gas sensor.

[0049] In some optional embodiments, the camera's field of view can cover a preset area. If the preset area is large, multiple cameras can be used to cover the entire preset area. The camera can capture images or videos of the preset area as sensor data collected by the camera.

[0050] In some optional embodiments, the camera type can be a monocular camera, a binocular camera, etc., and there is no specific limitation.

[0051] In some optional embodiments, the smoke detector can detect smoke concentration and send the smoke concentration value as sensor data collected by the smoke detector to the smart identifier 12. Alternatively, if the smoke detector detects a smoke concentration greater than a threshold, it can send an alarm signal to the smart identifier 12, with the alarm signal serving as sensor data for the smoke detector. Optionally, a smoke detector corresponding to each sub-area can be installed above it to locate the target sub-area where a fire has occurred, or to assist in locating the target sub-area where a fire has occurred, based on the data collected by the smoke detector.

[0052] In some optional embodiments, the temperature sensor can detect the temperature of a preset area and send the temperature as sensor data to the intelligent identifier 12. Alternatively, if the temperature sensor detects that the ambient temperature is higher than a temperature threshold, it can send an alarm signal as sensor data to the intelligent identifier 12. Optionally, a temperature sensor corresponding to each sub-area can be set above each sub-area to locate the target sub-area where a fire has occurred, or to assist in locating the target sub-area where a fire has occurred, based on the data collected by the temperature sensor.

[0053] In some optional embodiments, the infrared sensor can detect the ambient temperature by sensing changes in infrared light in the environment to identify a fire, and can send the detected data to the intelligent identifier 12. Optionally, a temperature sensor corresponding to each sub-area can be set above each sub-area to locate the target sub-area where the fire has occurred, or to assist in locating the target sub-area where the fire has occurred, based on the data collected by the temperature sensor.

[0054] In some optional embodiments, the photoelectric sensor utilizes the alteration of light propagation characteristics by smoke generated during a fire to identify the fire, and can be used to assist in locating the target sub-region where the fire has occurred. Optionally, a photoelectric sensor corresponding to each sub-region can be placed above it to locate the target sub-region where the fire has occurred, or to assist in locating the target sub-region where the fire has occurred, based on the collected data.

[0055] In some optional embodiments, gas sensors can detect changes in the concentration of carbon dioxide, carbon monoxide, etc., in the environment to identify fires, and can be used to assist in locating the target sub-area where a fire has occurred. Optionally, a gas sensor corresponding to each sub-area can be placed above it to locate the target sub-area where a fire has occurred, or to assist in locating the target sub-area where a fire has occurred, based on the collected data.

[0056] The embodiments of this disclosure identify the fire situation in each sub-area by combining a camera with at least one of a smoke detector, a heat detector, an infrared sensor, a photoelectric sensor, and a gas sensor. This can increase the characteristic information in the environment associated with the fire, thereby further improving the accuracy of the fire identification results.

[0057] Figure 3 This is a schematic diagram of the structure of a fire suppression device provided in another exemplary embodiment of this disclosure.

[0058] In some alternative embodiments, such as Figure 3 As shown, the fire suppression device 10 may also include a delivery pipeline 16 and a fire extinguishing agent bottle 17.

[0059] In some alternative embodiments, based on any of the above embodiments, the intelligent identifier 12 is configured with a fire identification algorithm model.

[0060] The fire detection algorithm model can include one or more of the following: fire detection algorithm models corresponding to different types of sensor data, or fire detection algorithm models that integrate at least two types (i.e., multimodal) of sensor data. Examples include fire detection algorithm models based on data collected by smoke detectors, fire detection algorithm models based on images (or videos) collected by cameras, fire detection algorithm models based on data collected by heat detectors, fire detection algorithm models based on image and smoke detector data, etc., and can be configured according to actual needs.

[0061] The intelligent identifier 12 is configured to: identify whether a fire has occurred in each sub-area based on sensor data and a fire identification algorithm model; and, if a fire is detected in a target sub-area within a preset area, send a fire signal corresponding to the target sub-area to the controller 15. The fire signal includes identification information corresponding to the target sub-area or identification information of the zone control valve 14 corresponding to the target sub-area.

[0062] The controller 15 is specifically configured to open the zone control valve 14 corresponding to the target sub-zone based on the fire signal corresponding to the target sub-zone.

[0063] In some optional embodiments, when a fire is detected in a target sub-area, the intelligent identifier 12 can generate a fire signal based on the identification information of the target sub-area (e.g., sub-area number), and send the identification information of the target sub-area in the fire signal to the controller 15. The controller 15 can be pre-configured with the correspondence between the identification information of different sub-areas and the zone control valves. The controller 15 can determine the zone control valve corresponding to the target sub-area based on the identification information of the target sub-area and the correspondence, and then control the zone control valve 14 corresponding to the target sub-area to open, so that the nozzles 13 of the target sub-area can spray fire extinguishing agents in a timely manner to extinguish the fire.

[0064] In some optional embodiments, the intelligent identifier 12 may be configured with a correspondence between the identification information of different sub-regions and the identification information of the zone control valve. When a fire is detected in a target sub-region, the intelligent identifier 12 can determine the identification information of the target zone control valve corresponding to the target sub-region based on the identification information of the target sub-region and the correspondence. Then, a fire signal is generated based on the identification information of the target zone control valve, and the identification information of the target zone control valve is carried in the fire signal and sent to the controller 15. The controller 15 can extract the identification information of the target zone control valve from the fire signal and control the zone control valve 14 corresponding to the target sub-region to open based on the identification information of the target zone control valve.

[0065] In the embodiments of this disclosure, when the intelligent identifier detects a fire in any target sub-area, it can carry the identification information of the target sub-area or the identification information of the corresponding zone control valve in the fire signal and send it to the controller. This enables the controller to promptly know that a fire has occurred in the target sub-area and to accurately control the opening of the corresponding zone control valve, thereby promptly and accurately extinguishing the fire in the target sub-area. This effectively suppresses the fire and avoids or reduces asset losses in other sub-areas.

[0066] In some optional embodiments, based on any of the above embodiments, the smart identifier 12 can be connected to a server; the smart identifier 12 is also configured to:

[0067] Receive upgrade data for the fire identification algorithm model from the server; upgrade the fire identification algorithm model based on the upgrade data.

[0068] The server can be the backend server of the intelligent identifier 12, and the upgrade data for the fire identification algorithm model can include the optimized algorithm model of the currently configured fire identification algorithm model in the intelligent identifier 12. The intelligent identifier 12 can upgrade the fire identification algorithm model according to the upgrade data through a pre-configured upgrade program, so that the upgraded intelligent identifier 12 can more accurately and timely identify the fire in each sub-area.

[0069] In the embodiments of this disclosure, by connecting the intelligent identifier to the server and combining the upgrade function of the intelligent identifier, the fire identification algorithm model can be upgraded in real time or at regular intervals, thereby continuously improving at least one of the performance, accuracy, and real-time performance of the fire identification algorithm.

[0070] In some alternative embodiments, based on any of the above embodiments, such as Figure 3 As shown, the device may also include an alarm 18 connected to the controller 15.

[0071] The controller 15 is also configured to send an alarm indication signal to the alarm 18 when the smart identifier 12 identifies a fire in a target sub-area within a preset area.

[0072] Alarm 18 is configured to perform an alarm operation in response to an alarm indication signal.

[0073] Among them, the alarm indication signal is an indication signal used to instruct the alarm device 18 to sound an alarm. The specific format or content of the alarm indication signal can be set according to the format or content supported by the alarm device.

[0074] In some optional embodiments, the alarm 18 can be any type of alarm, such as an audible and visual alarm, a voice alarm, etc., without specific limitations. An audible and visual alarm can emit a warning sound and a light of a specified color (e.g., red) when an alarm is triggered. A voice alarm can emit a voice related to the fire, such as "Fire! Fire!"

[0075] In the embodiments of this disclosure, by setting up an alarm, an alarm can be triggered in a timely manner when a fire is detected in a target sub-area, enabling relevant personnel in the vicinity to discover the fire in time and take appropriate countermeasures, thereby further improving safety.

[0076] In some alternative embodiments, based on any of the above embodiments, the smart identifier 12 and the controller 15 are respectively connected to the server.

[0077] In some alternative embodiments, the smart identifier 12 and the controller 15 can be connected to the server via a network or other means, enabling the smart identifier 12 and the controller 15 to communicate with the server in real time.

[0078] The intelligent identifier 12 is also configured to generate a fire work order when a fire is detected in a target sub-area within a preset area, and send the fire work order to the server so that the server can display the fire work order to the management user.

[0079] Controller 15 is also configured as follows:

[0080] If no instruction is received from the server within a preset time period, the control valve of the corresponding zone for the target sub-area is opened to control the sprinkler head of the target sub-area to spray fire extinguishing agent; or, if an instruction is received from the server within a preset time period, the operation corresponding to the instruction is executed.

[0081] The fire alarm work order may include at least one of the following: information indicating fire or smoke, identification information of the target sub-area where the fire has occurred, and other relevant information. The specific content of the fire alarm work order can be set according to actual needs, and this embodiment does not limit it. The preset duration can be set to any duration, such as 20 seconds, 30 seconds, 60 seconds, etc., and is not specifically limited. The indication information from the server may include any one of the following: indication information to start the partition control valve of the target sub-area (or simply start indication information), indication information to start the partition control valve of other sub-areas, or non-start indication information. The indication information can be triggered by the management user. For example, the management user can check and confirm whether a fire has indeed occurred in the preset area through monitoring video. If it is determined that a fire has occurred in the target sub-area, the management user can trigger the server to send start indication information to the controller 15 through remote control. In response to the start indication information, the controller 15 controls the partition control valve 14 corresponding to the target sub-area to open and spray fire extinguishing agent in a timely manner. If the management user determines that no fire has occurred in the preset area, the management user can trigger the server to send non-start indication information to the controller 15. If the controller 15 responds to the no-start instruction, it does not need to control the opening of the zone control valve 14 corresponding to the target sub-area. If the management user determines that the fire is not in the target sub-area but in another sub-area (which can be called the first sub-area), the server can be triggered to send an instruction to the controller 15 carrying the identification information of the first sub-area where the fire actually occurred or the identification information of the zone control valve corresponding to the first sub-area. The controller 15 determines the zone control valve that needs to be opened based on the instruction information and then opens the corresponding zone control valve.

[0082] In some optional embodiments, the server can connect to the terminal device of the management user and display the fire work order to the management user through the terminal device. The terminal device includes, but is not limited to, mobile phones, computers, tablets and any other terminal device that can realize display function.

[0083] In some optional embodiments, a fire work order notification function can also be set on the server side. That is, after the server receives a fire work order from the smart identifier 15, it sends a notification message through the terminal device. The notification method includes, but is not limited to, pop-up window, SMS, telephone, etc., so as to prompt the management user to respond in a timely manner.

[0084] In the embodiments of this disclosure, through the interaction between the intelligent identifier, the controller, and the server, the fire work order can be displayed to the management user, allowing the management user to further confirm whether a fire has indeed occurred and whether the sub-area where the fire occurred is indeed the target sub-area identified by the intelligent identifier. Furthermore, the operation of the controller can be remotely triggered, which can effectively avoid misidentification and identification errors, and further improve the accuracy and effectiveness of fire suppression.

[0085] In some optional embodiments, based on any of the above embodiments, the intelligent identifier 12 is further configured to: send the monitoring video data of the preset area collected by the camera in the sensor 11 to the server, so that the server can display the monitoring video data, so that the management user can remotely control whether to open the partition control valve 14 corresponding to the target sub-area according to the monitoring video.

[0086] Among them, sensor 11 can send the collected monitoring video data to intelligent identifier 12 in real time. After acquiring the monitoring video data, intelligent identifier 12 sends it to the server in real time. The server can display the monitoring video on the monitor, so that management users can view the situation of the preset area in real time through the monitoring video. In the event of a fire, the controller 15 can be remotely controlled according to the monitoring video, which further improves the accuracy and reliability of fire identification.

[0087] Figure 4 This is a schematic diagram of the structure of a fire suppression device provided in another exemplary embodiment of the present disclosure.

[0088] In some optional embodiments, based on any of the above embodiments, the first input end of the delivery pipeline 16 is connected to the fire extinguishing agent bottle; the second input end of the delivery pipeline 16 is connected to the fire hose 19; the first input end is provided with a first control valve 21 corresponding to the fire extinguishing agent bottle 17; and the second input end is provided with a second control valve 22 corresponding to the fire hose.

[0089] The controller 15 is also configured to: when the smart identifier 12 detects a fire in a target sub-area within a preset area, keep the second control valve 22 closed and open the first control valve 21; and after the zone control valve 14 corresponding to the target sub-area is opened, in response to the completion of the spraying of the extinguishing agent from the extinguishing agent bottle 17, control the first control valve 21 to close and open the second control valve 22 so that the nozzle 13 corresponding to the target sub-area continues to spray water.

[0090] The first control valve 21 and the second control valve 22 can be any implementable control valve, and can be set according to actual needs. This embodiment of the disclosure is not limited to any particular type, as long as it can achieve timed spraying of extinguishing agents and water. The fire hose 19 can be connected to a fire water source to ensure that when the sprinkler head 13 needs to spray water, water from the fire water source can be delivered to the sprinkler head 13 through the fire hose and delivery pipeline. This embodiment of the disclosure does not limit the configuration of the fire hose 19 and the fire water source.

[0091] In some optional embodiments, the first control valve 21 and the second control valve 22 can remain closed when there is no fire. Upon detection of a fire in a target sub-area, or upon receiving an instruction from the server requiring fire suppression, the second control valve 22 remains closed, and the first control valve 21 is opened. This ensures that, with the zone control valve 14 of any sub-area experiencing a fire open, the extinguishing agent in the extinguishing agent bottle 17 can be delivered to the corresponding sprinkler head 13 for spraying. After the extinguishing agent in the extinguishing agent bottle 17 has been sprayed, the first control valve 21 can be closed, and the second control valve 22 can be opened, allowing water to be delivered to the corresponding sprinkler head via the fire hose and delivery pipeline 16 for continued fire suppression, ensuring the fire is completely contained. Optionally, whether the extinguishing agent in the extinguishing agent bottle 17 has been completely sprayed can be determined by a corresponding detection method, or a corresponding time threshold can be configured in the controller 15 based on the continuous spraying time of the extinguishing agent obtained from the experiment. The controller 15 starts the timer when spraying begins, and when the timer reaches the time threshold, it controls the first control valve 21 to close and the second control valve 22 to open.

[0092] In some optional embodiments, in the absence of a fire, the first control valve 21 can be opened by default, while the second control valve 22 can remain closed. This allows for rapid spraying of extinguishing agents after opening any zone control valve 14, reducing delays.

[0093] In some optional embodiments, the management user can also remotely control whether to continue spraying water via a server. Alternatively, after spraying water has started, if the management user confirms that the fire hazard has been eliminated, they can remotely control the water spraying to stop. Specifically, the management user can trigger the server to send a corresponding instruction signal to the controller 15, so that the controller 15 opens or closes the second control valve 22 according to the instruction signal.

[0094] In the embodiments disclosed herein, the fire extinguishing agent bottle and the fire hose are connected simultaneously through a delivery pipeline, so that water can continue to be sprayed after the fire extinguishing agent has been sprayed, which can ensure the reliability of fire suppression.

[0095] In some alternative embodiments, based on any of the above embodiments, the sensor package 11 includes a camera; the smart recognizer 12 is specifically configured as follows:

[0096] Based on images captured by cameras, a pre-configured, pre-trained zone fire identification model is used to determine the identification results corresponding to each sub-region in a preset area. The identification result corresponding to any sub-region includes the confidence level that a fire has occurred in that sub-region. Based on the identification results corresponding to each sub-region, it is determined whether a fire has occurred in each sub-region.

[0097] The zonal fire identification model can be pre-trained based on labeled image samples and tags to obtain an initial zonal fire identification model. The confidence level of a fire occurring in any sub-region represents the degree of certainty that a fire has occurred in that sub-region. By setting a confidence threshold, the confidence level of each sub-region is compared with the threshold, and the result of the comparison determines whether a fire has occurred in each sub-region. For example, if the confidence level of a sub-region is greater than the confidence threshold, it is determined that a fire has occurred in that sub-region; otherwise, it is determined that no fire has occurred in that sub-region.

[0098] The embodiments of this disclosure configure an image-based zoned fire identification model in the intelligent identifier, enabling the intelligent identifier to effectively identify whether a fire has occurred in each sub-region based on images captured in real time by a camera. Since the zoned fire identification model is pre-trained, through training, the model can learn the complex correlation between the fire in each zone and the environmental features perceived by the image, giving the model a high generalization ability. Therefore, the accuracy of the identification results for each sub-region can be ensured, thereby improving the accuracy and effectiveness of fire identification.

[0099] In some optional embodiments, the extinguishing agent in the extinguishing agent bottle 17 is any one of foam extinguishing agent, aerosol extinguishing agent, microcapsule extinguishing agent, etc.

[0100] Foam extinguishing agents can extinguish flammable and combustible liquids. They primarily create a coagulated foam layer on the liquid surface, providing suffocation and cooling. Aerosol extinguishing agents can be used to extinguish fires in storage tanks containing certain organic chemicals and oils. The effective extinguishing substance in aerosol extinguishing agents is produced by a highly efficient aerosol-generating agent and a novel extinguishing composition. The large amount of inert gas generated by the oxidation-reduction reaction of the highly efficient aerosol-generating agent propels its own effective extinguishing substance and the highly efficient extinguishing medium produced by the thermal decomposition of the novel extinguishing composition out of the nozzle. The extinguishing composition, through its own sublimation, thermal decomposition, or endothermic chemical reactions, acts as a chemical coolant. Microcapsule extinguishing agents are a new type of highly efficient fire extinguishing, explosion-proof, and environmentally friendly safety technology product based on microcapsule technology. They can effectively extinguish fires, reduce the concentration of flammable and explosive gases, eliminate dangerous leaked liquids, cool and extinguish metal fires, and prevent reignition. When a battery (especially a lithium battery) experiences thermal runaway, the release of electrical energy further exacerbates heat generation. This cumulative and mutually reinforcing destructive process can lead to electrolyte splashing, ultimately causing combustion. Given this characteristic of batteries, fire extinguishing agents should be selected from foam extinguishing agents, aerosol extinguishing agents, or microencapsulation extinguishing agents. In particular, microencapsulation extinguishing agents (such as F-500 extinguishing agent) have become the best choice for suppressing various types of battery fires.

[0101] In some optional embodiments, the preset area is a battery storage area; the battery storage area is provided with a first number of trays, each tray corresponding to a sub-area; at least one nozzle 13 is provided above each tray.

[0102] The first quantity can be set according to the actual size of the storage area, and this embodiment does not impose a limitation. See also Figure 1 In this system, each sub-area can hold one tray.

[0103] The fire suppression device provided in the embodiments of this disclosure can serve as a small, low-cost, and highly reliable independent automatic fire extinguishing system. Relying on an intelligent identifier to detect fires in battery storage areas (e.g., lithium battery storage areas), it can quickly, accurately, and effectively detect and extinguish fire sources. Integrating alarm and fire suppression functions, it extinguishes fires in their initial stages, significantly reducing fire suppression costs, minimizing fire damage, and preventing injury to personnel. Through localized fire suppression, the protection of large enclosed spaces, as in related technologies, can be shifted to directly protecting valuable equipment in various smaller spaces.

[0104] The relevant technologies mainly involve fire suppression devices for electric vehicle parking sheds. These devices involve installing sprinklers above the parking sheds and connecting them to a fire extinguishing agent supply system. The system triggers a full-range sprinkler system based on smoke detectors. However, this approach has several drawbacks. First, smoke detectors are prone to false alarms, and automatic sprinkler systems can cause significant damage at the scene. Second, full-range sprinkler systems can cause substantial property damage around the fire site. Furthermore, the fire extinguishing agents used in these technologies are primarily designed to extinguish fires involving electric vehicles and are less effective against lithium batteries, posing a risk of reignition.

[0105] Compared to related technologies, the fire suppression device provided in this disclosure is equipped with an intelligent identifier, integrating monitoring and fire detection. It can effectively identify smoke and open flames within the monitored area and send work orders to the backend server. The work orders can be displayed on backend terminal devices and / or contacted via telephone or SMS to relevant management users. These users can promptly confirm the on-site fire situation through monitoring and remotely confirm whether to activate the fire extinguishing function, avoiding unnecessary losses. Secondly, by dividing the area into sub-zones and adding zone control valves to the sprinkler pipes, fire can be extinguished in the identified sub-zones where fires have occurred, preventing large-scale spraying from causing further losses outside the identified fire sub-zones. Thirdly, by combining fire extinguishing agents suitable for battery storage areas, it can effectively cool and extinguish battery metal fires, prevent reignition, and improve fire extinguishing effectiveness. Furthermore, the fire suppression device of this disclosure is not affected by location and can be extended into various narrow and complex flammable spaces. It can continuously extinguish fires by connecting to fire hoses, allowing for close proximity to the protected object, high fire suppression efficiency, and low cost. This further compensates for the shortcomings of related fire protection products that are unsuitable for narrow and complex flammable spaces. In addition, the fire suppression device of this disclosure, through an intelligent identifier combined with sensors such as cameras and smoke detectors, can effectively identify smoke and open flames within the monitoring range. It is not easily affected by oil or dust, which could weaken its function or cause false alarms, further ensuring the accuracy and effectiveness of fire identification.

[0106] The embodiments described above can be implemented individually or in any combination without conflict. The specific implementation can be set according to actual needs, and this disclosure does not limit them.

[0109] In some alternative embodiments, the fire suppression device 10 can be connected to the server 31 via a network. The network can provide a communication link between the fire suppression device 10 and the server 31.
