[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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.

[0038] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but in a possible example also includes steps or units that are not listed, or in a possible example also includes other steps or units inherent to these processes, methods, products or devices.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The electronic devices involved in the embodiments of the present application may include various handheld devices with wireless communication functions (mobile phones, tablet computers, etc.), desktops, vehicle-mounted devices, wearable devices (smart watches, smart bracelets, wireless headphones, augmented reality / virtual reality devices, smart glasses), computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, etc. For the convenience of description, the above-mentioned devices are collectively referred to as electronic devices. For example, the electronic device can be installed in a fire management system, and the electronic device may include a fire host and / or a detector.

[0041] The present application proposes a fire management method and system, which are described in detail below.

[0042] See also Figure 1 , Figure 1 A schematic diagram of the architecture of a fire management system provided in an embodiment of the present application. The fire management system includes a fire main warehouse and multiple battery compartments.

[0043] Among them, the fire main warehouse includes a fire main unit, fire gas cylinders and the main solenoid valves corresponding to the fire gas cylinders.

[0044] Among them, the battery compartment is installed in the energy storage container. Each battery compartment is composed of a battery cluster composed of battery modules. Each battery compartment is equipped with detectors, explosion-proof exhaust fans, electric shutters, sound and light alarms, do not enter signs for deflation, emergency start and stop switches, combustible gas detectors (H2, CO), point-type photoelectric smoke detectors, point-type temperature detectors, suppressant release pipelines, sprinklers, water sprinkler pipelines, sprinklers and other components or actuators.

[0045] For example, each battery compartment may correspond to a sub-solenoid valve, and each battery cluster in the battery compartment may also be provided with a sub-solenoid valve connected to the sub-solenoid valve for spraying gas fire-fighting medium on the battery cluster.

[0046] For example, the above-mentioned detectors include various types, such as smoke sensors, temperature sensors, and integrated gas detectors. The fire host is set in the fire main warehouse. All smoke sensors, temperature sensors, and integrated gas detectors are connected to the fire host through cables. The fire host can locate and process various detector data in each battery compartment.

[0047] Among them, the fire-fighting gas cylinder in the main fire-fighting warehouse is connected to the fire-fighting pipes of each battery compartment through fire-fighting pipes. The main fire-fighting gas cylinder is provided with a main solenoid valve, and the fire-fighting pipe of each battery compartment is provided with a sub-solenoid valve to control the spraying of the gas fire-fighting medium, and can also be used to control the sub-solenoid valve to spray different battery clusters.

[0048] It should be noted that the volume of the fire cylinder is related to the number of multiple battery compartments. For example, one fire warehouse corresponds to n battery compartments corresponding to n energy storage containers, n is a positive integer greater than 1, and the volume of the fire cylinder installed in the fire warehouse is the volume of a single fire cylinder under normal circumstances * n. Based on this, when the fire cylinders are concentrated on the target battery compartment for fire fighting, compared with the solution of setting up a fire cylinder for each energy storage container separately, the number of fire spraying can be greatly increased without increasing the cost of fire fighting media, which is beneficial to improving the fire extinguishing effect.

[0049] It should be noted that in the present application, a fire management system is adopted in which a fire host controls multiple battery compartments. Multiple battery compartments share one fire host and the control module and action module of the fire host. When problems occur in the control module and the action module, and the corresponding fire management functions of the multiple battery compartments fail, the power module with the fire management system as the core adopts a one-in-one-standby design, and a corresponding UPS backup power supply. When a fire occurs, it can effectively prevent the failure of the fire management system caused by sudden failure of the power module at the core of the fire management system, thereby ensuring the operational stability of the fire management system.

[0050] It should be noted that the “multiple” in the present application may refer to two or more than two, which will not be repeated later.

[0051] In a possible example, the battery compartment is used to obtain the evaluation parameters of each battery cluster, and determine the warning level of each battery cluster according to the preset fire warning threshold corresponding to each evaluation parameter; determine the battery cluster whose warning level reaches the highest warning level as the target battery cluster and the battery compartment as the target battery compartment, and send a fire alarm signal to the fire host in the fire main warehouse, the fire alarm signal is used to request the spraying of a preset fire extinguishing concentration of gas fire fighting medium, the fire alarm signal carries the location information of the target battery compartment and / or the location information of the target battery cluster, and the target evaluation parameter corresponding to the highest warning level; and according to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold, control the relevant devices in the battery compartment to perform corresponding operations at different warning levels;

[0052] The above-mentioned fire host is used to receive the fire alarm signal sent by the target battery compartment, and the target battery compartment is any one of a plurality of battery compartments; in response to the fire alarm signal, obtain the position information of the target battery compartment; based on the position information, control the main solenoid valve and the sub-solenoid valve corresponding to the target battery compartment to open, and control the sub-solenoid valve corresponding to the target battery compartment to spray a gas fire-fighting medium with a preset fire-extinguishing concentration.

[0053] It should be noted that the electronic device in the embodiment of the present application may also be a server, and the fire management method or system may also be applied to a server, which may include but is not limited to a background server, a component server, a fire management system server or a fire management software server. For example, Figure 1 The server may include a fire host and a detector. The fire host is applied to or set in a fire main warehouse. The fire main warehouse also includes a fire cylinder and a main solenoid valve corresponding to the fire cylinder. The fire main warehouse is connected to multiple battery compartments. The volume of the fire cylinder is related to the number of multiple battery compartments. Each battery compartment is provided with a sub-solenoid valve. The fire host is used to locate the position of each battery compartment and control the battery compartment separately; the detector is arranged in the battery compartment, multiple battery compartments correspond to multiple detectors, and each battery compartment can be provided with at least one such detector. The fire host can communicate with multiple detectors through the Internet, and the server controls the sub-solenoid valve corresponding to the target battery compartment to spray a preset fire extinguishing concentration of gas fire fighting medium; or, if the battery compartment includes multiple battery clusters composed of battery modules, each battery cluster is provided with a sub-solenoid valve connected to the sub-solenoid valve, and the server can also control the sub-solenoid valve corresponding to the target battery cluster in the above-mentioned target battery compartment to open, and spray a preset fire extinguishing concentration of gas fire fighting medium to the target battery cluster.

[0054] It can be seen that in this example, when the warning level of the battery cluster in the battery compartment reaches the highest warning level, a fire is detected, and the battery cluster is determined to be a target battery cluster, and the battery compartment is determined to be a target battery compartment. The detector can generate a fire alarm signal and transmit the signal to the fire host in the fire main warehouse. The fire host opens the main solenoid valve of the fire cylinder and opens the sub-solenoid valve of the target battery compartment at the same time. The volume of the fire cylinder is related to the number of multiple battery compartments. All fire-fighting media can be concentrated to spray the target battery compartment to achieve targeted and efficient fire extinguishing, which is conducive to improving the fire extinguishing effect.

[0055] See also Figure 2A , Figure 2A A flowchart of a fire management method provided in an embodiment of the present application. Figure 1 The fire host is arranged in a fire main warehouse, the fire main warehouse also includes a fire cylinder and a main solenoid valve corresponding to the fire cylinder, the fire main warehouse is connected to a plurality of battery compartments, the volume of the fire cylinder is related to the number of the plurality of battery compartments, each of the battery compartments is provided with a sub-solenoid valve, and the fire host is used to locate the position of each battery compartment and control the battery compartment separately; the method comprises:

[0056] S201. The fire host receives a fire alarm signal sent by a target battery compartment, where the target battery compartment is any one of the multiple battery compartments.

[0057] Among them, the present application adopts a centralized fire-fighting design and a centralized fire-fighting gas cylinder to achieve fire-fighting for multiple battery compartments through one fire-fighting gas cylinder.

[0058] Among them, the fire host can detect or receive a fire alarm signal, and the fire alarm signal is used to indicate that a fire has occurred in a target battery compartment, and the above-mentioned target battery compartment is a battery compartment that needs fire fighting.

[0059] Optionally, when the battery compartment includes a plurality of battery clusters composed of battery modules, the fire alarm signal is also used to indicate that a fire occurs in one or more target battery clusters in the target battery compartment.

[0060] S202: The fire host obtains the location information of the target battery compartment in response to the fire alarm signal.

[0061] When the detector reports the fire alarm signal, it can carry the location information of the corresponding target battery compartment. The fire host can obtain the location information of the target battery compartment from the fire alarm signal.

[0062] S203. The fire host controls the main solenoid valve and the sub-solenoid valve corresponding to the target battery compartment to open based on the position information, and controls the sub-solenoid valve corresponding to the target battery compartment to spray the gas fire-fighting medium with a preset fire-extinguishing concentration.

[0063] Among them, the fire host can locate the position information of the detector of the target battery compartment where the fire occurs to determine its corresponding sub-solenoid valve.

[0064] The preset fire extinguishing concentration dosage can be set by the user or by the system default, and is not limited here. Generally, it can be set to 6% or 8%.

[0065] In one possible example, controlling the sub-solenoid valve corresponding to the target battery compartment to spray the gas fire-fighting medium may include the following steps: determining the distance between the target battery compartment and the main fire-fighting compartment; if the distance is greater than a preset threshold, controlling a centrifugal pump or an air compressor to perform secondary pressurization on the gas fire-fighting medium, and determining the number of spraying times for the target battery compartment; based on the number of spraying times, controlling the sub-solenoid valve corresponding to the target battery compartment to spray the gas fire-fighting medium.

[0066] Among them, based on the centralized fire protection design of this application, the fire-fighting gas cylinder may be set in the electrical compartment. Since there is a long distance between the electrical compartment and the battery compartment, the fire-fighting gas cylinder in the electrical compartment is used to extinguish the fire in the distant battery compartment. The fire-fighting gas pressure may be insufficient, affecting the fire-fighting effect. Figure 2B As shown in FIG. 1 , a schematic diagram of the architecture of a fire management system is shown in FIG. Figure 1 In the fire management system shown, components such as a centrifugal pump or an air compressor can also be installed in the fire main compartment, and the gas fire fighting medium can be secondary pressurized by the centrifugal pump or the air compressor to effectively extinguish the fire in the battery compartment that is far away.

[0067] Among them, the above-mentioned preset threshold can be set by the user or by the system default, and is not limited here; the preset threshold is used to evaluate the longest distance at which the fire gas pressure can extinguish the fire in the target battery compartment. When the distance between the target battery compartment and the fire main warehouse is greater than the preset threshold, the gas pressure in the fire cylinder is insufficient and the target battery compartment cannot be effectively extinguished.

[0068] Among them, the above-mentioned spraying times can be preset. For example, it can be set according to the danger level of the target battery compartment. The higher the danger level, the higher the spraying times can be set. It can also be set according to the volume of the gas fire-fighting medium in the fire-fighting gas cylinder in the fire-fighting main warehouse. For example, if the fire-fighting gas cylinder is a 400L fire-extinguishing agent storage tank, it can hold up to 600Kg of perfluorohexanone agent. When perfluorohexanone is sprayed continuously for 2 minutes each time for continuous suppression and cooling, 18 sprays can be performed through the solenoid valve.

[0069] It can be seen that in this example, components such as centrifugal pumps or air compressors can be installed in the fire main warehouse. When the distance between the fire main warehouse and the target battery compartment is far, the fire host can control the centrifugal pump or air compressor to perform secondary pressurization on the gas fire fighting medium, and based on the number of spraying times, control the sub-solenoid valves corresponding to the target battery compartment to spray the gas fire fighting medium with a preset fire extinguishing concentration, so as to effectively extinguish the fire in the target battery compartment that is far away.

[0070] In one possible example, the above method may include the following steps: if multiple fire alarm signals sent by multiple target battery compartments are received, and the number of target battery compartments is greater than the first preset protection number, then the intelligent polling spraying mode is started, and each target battery compartment corresponds to a fire alarm signal.

[0071] The fire host can also control the fire cylinder to spray a preset fire extinguishing concentration of gas fire fighting medium to multiple target battery compartments within a first preset protection quantity at the same time. The first preset protection quantity can be set by the user or by the system, and is not limited here.

[0072] It should be noted that, in this example, the first preset protection quantity corresponds to the battery compartment. For example, the preset protection quantity can be set according to the preset fire extinguishing concentration dosage and the maximum number of simultaneous spraying times.

[0073] For example, based on the fire extinguishing mode of the above-mentioned fire host for multiple battery compartments at the same time, when there are more target battery compartments with fire, due to the volume limitation of the gas fire fighting medium, it is impossible to extinguish the fire of all target battery compartments at the same time, and the intelligent polling spraying mode can be started. The intelligent polling spraying mode is used to perform fire extinguishing operations on multiple target battery compartments in different areas, time periods, danger levels or stages to suppress the fire in the target battery compartment where there is fire.

[0074] It can be seen that in this example, the fire host can control the fire cylinder to synchronously or simultaneously spray the gas fire-fighting medium with a preset fire-extinguishing concentration dose on the target battery compartments with a preset protection number. When the number of target battery compartments receiving the fire alarm signal is greater than the first preset protection number, the intelligent polling spraying mode can be started, which is conducive to ensuring the design concept of one fire host protecting multiple battery compartments at the same time.

[0075] Optionally, the fire host can also control the fire cylinder to spray a preset fire extinguishing concentration of gas fire-fighting medium to multiple target battery clusters within a preset protection number at the same time. When the battery compartment includes multiple battery clusters composed of battery modules, since the fire may spread or become serious in multiple battery clusters, the detector can also detect multiple target battery clusters (the warning level of the target battery compartment reaches the highest warning level), and obtain the location information of each target battery cluster, encapsulate the location information of the target battery cluster and the target battery compartment corresponding to the target battery cluster in the fire warning signal, and send the fire warning signal corresponding to each target battery cluster to the fire host. In this example, the fire host can receive multiple fire warning signals sent by multiple target battery clusters, and start the above-mentioned intelligent polling spraying mode when the number of multiple target battery clusters is greater than or equal to the second preset protection number corresponding to the battery cluster.

[0076] The above-mentioned multiple target battery clusters may correspond to the same battery compartment or to multiple different battery compartments, which is not limited here.

[0077] Furthermore, the above-mentioned intelligent polling spraying mode is used to execute the following steps: obtaining the target evaluation parameters corresponding to the highest warning level carried by the fire alarm signal of each target battery cluster; evaluating the danger level of each target battery cluster according to the target evaluation parameters; sorting the multiple target battery clusters according to the danger level; and controlling the sub-solenoid valves corresponding to each target battery cluster in sequence from large to small to spray the preset fire extinguishing concentration dose of the gas fire fighting medium according to the sorting of the multiple target battery clusters.

[0078] Among them, the battery compartment may correspond to a sub-solenoid valve, and each battery cluster may correspond to a sub-solenoid valve, which may be connected to the sub-solenoid valve. Then, in the above steps, the fire host controls the sub-solenoid valve corresponding to each target battery cluster in turn from large to small to spray the preset fire extinguishing concentration of the gas fire fighting medium. In the specific implementation, the fire host may obtain the location information of the target battery compartment, and based on the location information of the target battery compartment, control the sub-solenoid valve corresponding to the target battery compartment to open; and further obtain the location information corresponding to each target battery cluster; and according to the location information of each target battery cluster, according to the degree of danger from large to small, control the sub-solenoid valve corresponding to the location information of the target battery cluster to open one by one in turn, and control the sub-solenoid valve to spray the preset fire extinguishing concentration of the gas fire fighting medium to the target battery cluster, so as to realize the targeted intelligent spraying of multiple target battery clusters.

[0079] Among them, since the battery cluster is arranged relatively closely, compared with the battery compartment, the fire is very easy to spread in the above-mentioned battery cluster. Therefore, in order to extinguish the fire urgently and effectively, the first preset protection number of the above-mentioned battery cluster can be set to be smaller than the second preset protection number corresponding to the above-mentioned battery compartment.

[0080] It should be noted that the above-mentioned method of controlling the sub-electromagnetic valves corresponding to each target battery cluster to spray the gas fire-fighting medium with a preset fire-extinguishing concentration dose in sequence from large to small is the same as the method in the following example of this application, and will not be repeated here.

[0081] In one possible example, the above-mentioned intelligent polling spraying mode is used to perform the following steps: obtaining the target evaluation parameters carried by the fire alarm signal of each of the target battery compartments; evaluating the danger level of each of the target battery compartments according to the target evaluation parameters; sorting the multiple target battery compartments according to the danger level; and controlling the corresponding solenoid valves of each target battery compartment from large to small to spray the gas fire-fighting medium with the preset fire-extinguishing concentration dose according to the sorting of the multiple target battery compartments, and in this process, polling to obtain the fire alarm signal to spray the gas fire-fighting medium in a targeted manner.

[0082] The above-mentioned warning level is used to evaluate the fire condition or fire situation of the battery compartment or the battery cluster in the battery compartment. When the battery compartment or a battery cluster in the battery compartment reaches the highest warning level, the fire host can obtain the fire alarm signal sent by the target battery compartment in this case. The fire alarm signal may carry evaluation parameters to evaluate the target evaluation parameters of the battery compartment or battery cluster when the battery compartment is at the highest warning level. The above-mentioned evaluation parameters are used to evaluate the warning level and can be obtained by different types of detectors in the battery compartment.

[0083] For example, the above evaluation parameters may include at least one of the following: temperature, carbon monoxide concentration, electrolyte concentration, smoke concentration, etc., which are not limited here; the type of evaluation parameters corresponding to each warning level may be different, and the highest warning level corresponds to the target evaluation parameter. For example, the target evaluation parameters corresponding to the second warning level may include the three evaluation parameters of temperature, carbon monoxide concentration and electrolyte concentration; for example, the target evaluation parameters corresponding to the highest warning level in this example include the four evaluation parameters of temperature, carbon monoxide concentration, electrolyte concentration and smoke concentration.

[0084] Among them, the fire host can determine the danger level of each target battery compartment according to the various numerical values ​​specifically corresponding to the above-mentioned target evaluation parameters.

[0085] For example, the fire host may evaluate the danger level of each target battery compartment according to the target evaluation parameter and the importance of the target evaluation parameter to the fire situation.

[0086] For example, the danger level of each target battery compartment may be preferentially evaluated based on the target evaluation parameter with the highest importance. In a specific implementation, the target battery compartment with the highest temperature value may be set to have the highest danger level. When any two target battery compartments have the highest temperature value, they may be further evaluated based on the carbon monoxide concentration, and the target battery compartment with a higher carbon monoxide concentration may be selected as having a higher danger level. Furthermore, when the carbon monoxide concentrations of the above two target battery compartments are the same, the target battery compartment with a higher electrolyte concentration may be selected as having a higher danger level. The target battery compartments may be compared two by two in turn, thereby determining and ranking the danger levels of the target battery compartments.

[0087] As another example, the importance percentage of each target evaluation parameter can be determined. The importance percentages of temperature, carbon monoxide concentration, electrolyte concentration and smoke concentration are a%, b%, c% and d% respectively. The sum of the importance percentages of each target evaluation parameter is 1, that is, a%+b%+c%+d%=1. Then, the danger level x=a%*temperature+b%*carbon monoxide concentration+c% electrolyte concentration+d%*smoke concentration can be determined. Then, according to the danger level, multiple target battery compartments can be ranked. The higher the danger level, the higher the ranking.

[0088] Among them, when controlling the sub-solenoid valves corresponding to each target battery compartment to spray the preset fire extinguishing concentration dose of the gas fire fighting medium in sequence from large to small, in the specific implementation, the position information of each target battery compartment can be obtained; the main solenoid valve is controlled to open; and based on the sorting of each position information and the degree of danger, the sub-solenoid valves corresponding to each position information are controlled to open and spray the preset fire extinguishing concentration dose of the gas fire fighting medium in sequence from large to small in terms of the degree of danger.

[0089] Among them, the fire host can control the corresponding sub-solenoid valves to open in order from large to small according to the sorting of multiple target battery compartments, and spray the gas fire-fighting medium with a preset fire-extinguishing concentration to each target battery compartment one by one. Due to the restrictions on the number of spraying times and spraying time of the preset fire-extinguishing concentration of the gas fire-fighting medium, fire spread may occur in this process. Therefore, the fire alarm signal can be polled to obtain the fire alarm signal. The fire alarm signal can be sent by continuously updating the target evaluation parameters of other target battery compartments except for the one that is spraying the gas fire-fighting medium, or it can be sent for the first time by other battery compartments among multiple battery compartments except for multiple target battery compartments.

[0090] It should be noted that if there are target battery compartments with a number less than the preset protection number and corresponding to the same danger level at the same time, the operation of spraying the gas fire-fighting medium can be performed on the target battery compartments with the preset protection number at the same time.

[0091] It can be seen that in this example, when the number of target battery compartments that receive fire alarm signals is greater than the first preset protection number, the fire host can start or trigger the intelligent polling spraying mode, and evaluate the degree of danger of each target battery compartment according to the target evaluation parameters obtained by the detector, and target the battery compartments one by one in order from large to small according to the degree of danger, so as to suppress the fire in the most serious area or the most serious target battery compartment, and poll and monitor other target battery compartments that have not been sprayed or other battery compartments in multiple battery compartments except multiple target battery compartments, so as to obtain fire alarm signals in real time, and re-evaluate the degree of danger and sort the other target battery compartments that have not been sprayed or other battery compartments in multiple battery compartments except multiple target battery compartments, so as to achieve continuous spraying for each target battery compartment obtained by polling, which is beneficial to reduce the situation where the fire spreads and causes the fire to become more serious, minimize the losses, and enable the fire host to protect multiple battery compartments at the same time.

[0092] Optionally, this example can also be used for an intelligent polling spraying mode when the corresponding warning level of any target battery cluster in the target battery compartment reaches the highest level. At this time, the fire host receives fire alarm signals sent by multiple target battery compartments, and the fire alarm signals include the corresponding position information of the target battery compartment and the corresponding position information of the target battery cluster. The target evaluation parameters of the above-mentioned target battery compartment are the target evaluation parameters of the corresponding target battery cluster.

[0093] In a specific implementation, consistent with the above example, the fire host can obtain the target evaluation parameters of the target battery cluster corresponding to the highest warning level carried by the fire alarm signal of each target battery compartment, and obtain multiple target evaluation parameters corresponding to multiple target battery clusters; evaluate the danger level of each target battery compartment according to the multiple target evaluation parameters; sort the multiple target battery compartments according to the danger level; according to the sorting of the multiple target battery compartments, control the sub-solenoid valves corresponding to the target battery cluster in each target battery compartment in turn from large to small to spray the preset fire extinguishing concentration of the gas fire fighting medium, and in this process poll to obtain the fire alarm signal to spray the gas fire fighting medium in a targeted manner.

[0094] Among them, in terms of evaluating the danger level of each target battery compartment according to the multiple target evaluation parameters; and sorting the multiple target battery compartments according to the danger level, its specific implementation is consistent with the relevant explanations in the above examples and will not be repeated here.

[0095] Among them, when the sub-solenoid valves corresponding to the target battery cluster in each target battery compartment are controlled in sequence from large to small to spray the gas fire-fighting medium of the preset fire-extinguishing concentration, in the specific implementation, the position information of the target battery cluster corresponding to each target battery compartment in the multiple target battery compartments can be obtained from the fire alarm signal, and according to the position information of each target battery cluster, the sub-solenoid valve of the target battery cluster can be further determined. Finally, according to the ranking of the degree of danger, the sub-solenoid valves of each target battery compartment and the corresponding target battery cluster can be controlled to open at the same time from large to small, and each sub-solenoid valve can be controlled to spray the gas fire-fighting medium of the preset fire-extinguishing concentration.

[0096] Among them, the fire host can control the corresponding sub-solenoid valves to open in order from large to small according to the sorting of multiple target battery clusters, and spray the gas fire-fighting medium with a preset fire-extinguishing concentration to each target battery cluster one by one. Because of the restrictions on the number of spraying times and spraying time of the preset fire-extinguishing concentration of the gas fire-fighting medium, fire spread may occur in this process. Therefore, the fire alarm signal can be polled to obtain the fire alarm signal. The fire alarm signal can be that the target evaluation parameters of other target battery compartments other than the one being sprayed with the gas fire-fighting medium reach the highest warning level and are updated and sent, or it can be that the target evaluation parameters are updated and sent for the first time when the battery clusters in other battery compartments except the multiple target battery compartments reach the highest warning level, or it can be that the target evaluation parameters are updated and sent when the battery clusters other than the target battery cluster in the target battery compartment reach the highest warning level.

[0097] It can be seen that in this example, when the number of target battery compartments that receive fire alarm signals is greater than the first preset protection number, the fire host can start or trigger the intelligent polling spraying mode, and evaluate the danger level of each target battery compartment based on the target evaluation parameters of the target battery cluster detected by the corresponding detector of the target battery compartment, and spray the gas fire fighting medium on the internal target battery clusters one by one in descending order according to the danger level, so as to suppress the fire in the most serious area or the most serious target battery cluster, and for other target battery compartments that have not been sprayed, or battery clusters in other battery compartments except multiple target battery compartments, or battery clusters in the target battery compartment except the target battery compartment. The fire host can poll and monitor other battery clusters except the target battery cluster in real time to obtain fire alarm signals, and re-evaluate the target battery compartment corresponding to each fire alarm signal, or the danger level of one or more target battery clusters in the target battery compartment (which may include other battery clusters except the target battery cluster in other battery compartments except multiple target battery compartments) and perform operations such as sorting, so as to achieve continuous spraying for each target battery cluster obtained by polling, which is beneficial to reduce the more serious fire caused by the spread of fire, minimize the losses, and enable the fire host to protect multiple battery clusters in multiple battery compartments at the same time.

[0098] It should be noted that the target evaluation parameters of the target battery cluster or the target battery compartment are acquired through real-time monitoring. When the target evaluation parameters indicate that the warning level of the target battery cluster or the target battery compartment is reduced to the lowest warning level, such as the first-level warning level described below, the target battery compartment corresponding to the target battery cluster or the sub-solenoid valve of the target battery compartment is closed to stop the spraying operation of the gas fire-fighting medium to the target battery compartment.

[0099] Alternatively, if Figure 2C FIG. 1 is a schematic diagram of the architecture of a fire management system, and Figure 1 , Figure 2B Correspondingly, the fire management system includes cabin A, cabin B and cabin C. If a fire occurs in cabin A, the smoke, temperature and combustible gas detectors of the target battery cluster in cabin A detect the highest warning level and send a fire alarm signal to the fire host. Cabin A can control the sub-solenoid valve of the target battery cluster to open first, and then the fire host or cabin A can control the sub-solenoid valve to open first. When the main solenoid valve of the fire gas cylinder in the fire main warehouse is opened, the target cluster in cabin A can be centrally extinguished until the fire is extinguished.

[0100] At the same time, in the above-mentioned fire extinguishing process, considering that the fire may spread, the above-mentioned intelligent patrol spraying mode can also be activated. When other battery clusters in cabin B and / or cabin C, and / or cabin A catch fire at the same time, the above-mentioned cabins or the above-mentioned clusters can report fire alarm signals, and the fire-fighting host computer simultaneously obtains the fire alarm signals of the above-mentioned cabins or the above-mentioned clusters, and makes intelligent judgments on these fire alarm signals, dynamically monitors the target evaluation parameters in real time and sorts them according to the degree of danger, and gives priority to extinguishing the battery clusters or battery cabins with the highest degree of danger, and then extinguishes other battery clusters or battery cabins in turn to minimize the losses.

[0101] It can be seen that the fire management method described in the embodiment of the present application receives a fire alarm signal sent by a target battery compartment, and the target battery compartment is any one of the multiple battery compartments; in response to the fire alarm signal, obtains the location information of the target battery compartment; based on the location information, controls the main solenoid valve and the sub-solenoid valve corresponding to the target battery compartment to open, and controls the sub-solenoid valve corresponding to the target battery compartment to spray a gas fire-fighting medium with a preset fire-extinguishing concentration. In this way, the fire host receives the fire alarm signal sent by the target battery compartment, and is able to open the main solenoid valve of the fire-fighting gas cylinder, and at the same time open the sub-solenoid valve of the target battery compartment. The volume of the fire-fighting gas cylinder is related to the number of multiple battery compartments, and all fire-fighting media can be concentrated to spray the target battery compartment to achieve targeted and efficient fire extinguishing, which is conducive to improving the fire extinguishing effect.

[0102] See also Figure 3 , Figure 3A flowchart of a fire management method provided in an embodiment of the present application. Figure 1 , Figure 2A , Figure 2B and Figure 2C A detector included in any one of the battery compartments, wherein the battery compartment includes a plurality of battery clusters consisting of battery modules; the method comprising:

[0103] S301. The detector obtains evaluation parameters of each battery cluster, and determines the warning level of each battery cluster according to a preset fire warning threshold corresponding to each evaluation parameter.

[0104] For example, a corresponding detector may be provided for each battery cluster, respectively used to detect the evaluation parameters of each battery cluster. Alternatively, the evaluation parameters of each battery cluster may be obtained by detecting one detector.

[0105] For example, the above evaluation parameters may include at least one of the following: temperature, carbon monoxide concentration, electrolyte concentration, smoke detector sensitivity, etc., which are not limited here; the type of evaluation parameters corresponding to each warning level may be different.

[0106] The above evaluation parameters are obtained by acquiring or monitoring different types of detectors in the battery compartment.

[0107] Among them, the battery compartment may correspond to a sub-solenoid valve, and each battery cluster may correspond to a sub-solenoid valve, which may be connected to the sub-solenoid valve to realize the positioning of the battery cluster or to spray the gas fire-fighting medium on the battery cluster in a targeted manner to achieve a targeted fire-fighting effect.

[0108] Among them, different levels of preset fire warning thresholds can be set for each evaluation parameter, and the different levels of preset fire warning thresholds are used to evaluate the warning level of each battery cluster.

[0109] It should be noted that the present application evaluates the warning level for the smallest unit in the battery compartment, namely the battery cluster. When the battery compartment is the smallest unit, the warning level evaluation method in the present application is also applicable.

[0110] S302. The detector determines that the battery cluster whose warning level reaches the highest warning level is the target battery cluster and the battery compartment is the target battery compartment, and sends a fire alarm signal to the fire host in the fire main warehouse. The fire alarm signal is used to request the spraying of a gas fire-fighting medium with a preset fire-extinguishing concentration. The fire alarm signal carries the location information of the target battery compartment and / or the location information of the target battery cluster, as well as the target evaluation parameters corresponding to the highest warning level.

[0111] Among them, after sending the fire alarm signal, the detector can be used by the fire host to preferentially control the opening of the sub-solenoid valve of the target battery cluster according to the location information of the target battery cluster, and / or control the opening of the sub-solenoid valve of the target battery compartment according to the location information of the target battery compartment.

[0112] For example, after the main solenoid valve of the fire host is opened, the fire host controls the sub-solenoid valve of the target battery compartment to open, and further controls the sub-solenoid valve of the target battery cluster to open, and the gas fire-fighting medium flows from the sub-solenoid valve into the sub-solenoid valve, which can immediately control the sub-solenoid valve to spray the gas fire-fighting medium to the corresponding target battery cluster.

[0113] S303: The detector controls the relevant devices in the battery compartment to perform corresponding operations at different warning levels according to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold.

[0114] Among them, the above-mentioned related devices may include at least one of the following: explosion-proof exhaust fans, electric shutters, sound and light alarms, "Do not deflate" signs, emergency start and stop switches, etc., which are not limited here.

[0115] Among them, different preset fire warning thresholds and evaluation parameters of each battery cluster are used to evaluate the warning level of the corresponding battery cluster, and control the relevant devices to perform corresponding functional operations at different warning levels to slow down the spread of fire, or effectively suppress the fire from becoming more serious when the warning level does not reach the highest warning level.

[0116] For example, the detector determines the warning level according to the evaluation parameters of the battery cluster and the corresponding preset fire warning threshold, and determines the target wind speed level of the explosion-proof exhaust fan and the target opening degree of the electric shutters at different warning levels, and turns on the explosion-proof exhaust fan, adjusts the wind speed level of the explosion-proof exhaust fan to the target wind speed level, and controls the opening degree of the electric shutters to the target opening degree to achieve the exhaust function.

[0117] In a possible example, the above method may also include the following steps: if the warning level of each battery cluster does not reach the highest warning level, polling and monitoring the evaluation parameters of each battery cluster, so as to send the fire alarm signal to the fire host through the detector after determining the target battery cluster.

[0118] Among them, when there is a battery cluster among multiple battery clusters that has not reached the highest warning level, the evaluation parameters of other battery clusters except the target battery cluster in the monitoring can be polled, and their warning levels can be evaluated in real time according to the evaluation parameters. Once the warning level of other battery clusters is upgraded to the highest warning level, it will be used as the target battery cluster, and the fire alarm signal corresponding to the target battery cluster will be actively and continuously sent to the fire host.

[0119] It can be seen that in this example, considering that the fire may spread or become serious in the battery cluster, the detectors in the battery cluster can poll in real time to obtain the evaluation parameters of each battery cluster, evaluate its warning level in real time, and promptly report the fire alarm signal corresponding to the target battery cluster to the fire host, which is helpful to help the fire host to execute the spraying operation of the gas fire fighting medium on the target battery cluster in time, which is helpful to reduce the spread of fire.

[0120] In one possible example, determining the warning level of each battery cluster according to the preset fire warning threshold corresponding to each evaluation parameter may include the following steps: if the temperature of the evaluation parameters monitored for any battery cluster is greater than or equal to a first preset temperature threshold and less than a second preset temperature threshold, and / or the carbon monoxide concentration is greater than or equal to a first preset carbon monoxide concentration threshold and less than a second preset carbon monoxide concentration threshold, and / or the electrolyte concentration is greater than or equal to a preset electrolyte concentration threshold, then it is determined that the battery cluster is at the second warning level.

[0121] Among them, the types of evaluation parameters can be set for different warning levels, and the thresholds corresponding to the evaluation parameters at different warning levels can be set.

[0122] For example, the temperature evaluation parameter may be set to correspond to a preset temperature threshold for different warning levels. For example, the first preset temperature threshold corresponding to the second warning level may be set to 55°C, the second preset temperature threshold corresponding to the third warning level may be set to 65°C, and the third preset temperature threshold corresponding to the fourth warning level may be set to 75°C. The first preset temperature threshold is less than the second preset temperature threshold, and the third preset temperature threshold is greater than the second preset temperature threshold.

[0123] It should be noted that when the temperature in the evaluation parameters of any battery cluster is lower than the first preset temperature threshold, the carbon monoxide concentration is lower than the first preset carbon monoxide concentration threshold, and the electrolyte concentration is lower than the first preset electrolyte concentration threshold, it is determined that the battery cluster is at the first-level warning level. The first-level warning level can also be set to a situation where no warning is required, which can be a normal situation under normal working conditions; at the first-level warning level, there is no need for relevant devices to perform corresponding operations.

[0124] It can be seen that in this example, the battery compartment can set the type of evaluation parameters for different warning levels, as well as set the thresholds corresponding to the evaluation parameters at different warning levels, so as to evaluate the warning levels of different battery compartments, which is conducive to the subsequent control of related devices to perform corresponding operations, thereby reducing the probability of fire occurrence or slowing down the spread of fire.

[0125] In a possible example, according to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold, the relevant devices in the battery compartment are controlled to perform corresponding operations at different warning levels, including the following steps: controlling the sound and light alarm corresponding to the secondary warning level to perform corresponding operations.

[0126] Among them, different warning levels correspond to different related devices. Under the second-level warning level, the sound and light alarm can be controlled to perform corresponding operations.

[0127] It can be seen that in this example, after the detector in the battery cluster evaluates that the warning level of the battery cluster is the second-level warning level according to the preset fire warning threshold and evaluation parameters, it can control the sound and light alarm corresponding to the second-level warning level to emit a light alarm, etc., to alert the management personnel of the current alarm situation.

[0128] In a possible example, determining the warning level of each battery cluster according to the preset fire warning threshold corresponding to each evaluation parameter may further include the following steps:

[0129] If the temperature of any of the evaluation parameters of the battery cluster is greater than or equal to the second preset temperature threshold and less than the third preset temperature threshold, and / or the carbon monoxide concentration is greater than or equal to the second preset carbon monoxide concentration threshold, and / or the smoke concentration is greater than or equal to the preset smoke concentration threshold, it is determined that the battery cluster is at the third warning level; or,

[0130] If the temperature of any of the evaluation parameters of the battery cluster is greater than or equal to the third preset temperature threshold, and / or the carbon monoxide concentration is greater than or equal to the first preset carbon monoxide concentration threshold, and / or the electrolyte is greater than or equal to the preset electrolyte concentration threshold, and / or the smoke concentration is greater than or equal to the preset smoke concentration threshold, it is determined that the battery cluster is at the fourth warning level; or,

[0131] If the temperature of any of the evaluation parameters of the battery cluster monitored is greater than or equal to the third preset temperature threshold, and / or the carbon monoxide concentration is greater than or equal to the second preset carbon monoxide concentration threshold, and / or the smoke concentration is greater than or equal to the preset smoke concentration threshold, it is determined that the battery cluster is in a fourth-level warning, etc.

[0132] For example, the carbon monoxide evaluation parameter can be set to a preset carbon monoxide concentration threshold corresponding to different warning levels. For example, the second preset carbon monoxide concentration threshold corresponding to the second warning level can be set to 350ppm, and the second preset carbon monoxide concentration threshold corresponding to the third warning level can be set to 800ppm.

[0133] For another example, the preset electrolyte concentration threshold may be set to 2000 ppm, and the preset smoke concentration threshold may be set to 800 dm / m.

[0134] Among them, because smoke will be produced when the temperature reaches a certain value and the carbon monoxide concentration reaches a certain value, the smoke concentration can be added as an evaluation parameter when the warning level is evaluated as the third warning level.

[0135] Among them, when the evaluation warning level is the fourth warning level, the higher the temperature, the higher the carbon monoxide concentration, the greater the probability of smoke, or the higher the electrolyte concentration, the greater the probability of open flames. Of course, in this case, multiple evaluation parameters corresponding to the fourth warning level and the corresponding preset fire warning thresholds can also be set to send a fire alarm signal to the fire host when the battery cluster is evaluated to be at the fourth warning level.

[0136] It can be seen that in this example, the detectors in the battery cluster can be set with different warning levels, which is conducive to evaluating the current status of the battery cluster and facilitating the subsequent control of related devices to perform corresponding operations, thereby reducing the probability of fire occurrence or slowing down the spread of fire.

[0137] In a possible example, controlling the relevant devices in the battery compartment to perform corresponding operations at different warning levels according to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold includes the following steps:

[0138] Control the explosion-proof exhaust fan and electric shutter corresponding to the three warning levels to perform corresponding operations; or,

[0139] The sound and light alarms, the "Do Not Enter" sign, the explosion-proof exhaust fan and the electric shutters corresponding to the four warning levels are controlled to perform corresponding operations.

[0140] For example, when the warning level is the third warning level, the detector determines the target wind speed level of the explosion-proof exhaust fan and the target opening degree of the electric shutters based on the evaluation parameters of the corresponding battery cluster and the corresponding preset fire warning threshold, and turns on the explosion-proof exhaust fan, and adjusts the wind speed level of the explosion-proof exhaust fan to the target wind speed level, and controls the opening degree of the electric shutters to the target opening degree to achieve the exhaust function, which can reduce the carbon monoxide concentration of the battery cluster as much as possible, which is conducive to reducing the situation where the third warning level continues to develop to the fourth warning level.

[0141] For example, when the warning level is the fourth warning level, if the fourth warning level is the preset highest warning level, in addition to controlling the sound and light alarm, the do not enter sign, the explosion-proof exhaust fan and the electric shutters corresponding to the fourth warning level to perform corresponding operations, the battery cluster can also be determined as the target battery cluster. In this way, a fire alarm signal can be further sent to the fire host to open the sub-solenoid valve corresponding to the target battery cluster under the control of the fire host, so that after the fire host opens the main solenoid valve and / or the sub-solenoid valve corresponding to the target battery compartment, the preset fire extinguishing concentration of the gas fire fighting medium is sprayed through the sub-solenoid valve to spray the target battery cluster until the fire of the target battery cluster is extinguished, or the evaluation parameters of the target battery cluster are monitored until the evaluation parameters indicate that the warning level is reduced to the first warning level, that is, no warning is required, which can be a normal situation under normal operation, and then the spraying of the preset fire extinguishing concentration of the gas fire fighting medium is stopped.

[0142] It can be seen that in this example, after evaluating that the warning level of the battery cluster is different, the detector can control the relevant devices corresponding to the warning level to perform different relevant operations to achieve different warning purposes.

[0143] It can be seen that the fire management method described in the embodiment of the present application obtains the evaluation parameters of each battery cluster, and determines the warning level of each battery cluster according to the preset fire warning threshold corresponding to each evaluation parameter; determines the battery cluster whose warning level reaches the highest warning level as the target battery cluster and the battery compartment as the target battery compartment, and sends a fire alarm signal to the fire host in the fire headquarters, wherein the fire alarm signal is used to request the spraying of a preset fire extinguishing concentration of gas fire fighting medium, and the fire alarm signal carries the location information of the target battery compartment and / or the location information of the target battery cluster, as well as the target evaluation parameters corresponding to the highest warning level; according to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold, the relevant devices in the battery compartment are controlled to perform corresponding operations at different warning levels. In this way, when the warning level of the battery cluster in the battery compartment reaches the highest warning level, a fire is detected, and the battery cluster is determined to be a target battery cluster, and the battery compartment is determined to be a target battery compartment, the detector can generate a fire alarm signal and transmit the signal to the fire host in the fire main warehouse to implement fire extinguishing operations on the target battery cluster; at the same time, the relevant devices in the battery compartment can also be controlled to perform corresponding operations, which is helpful to help extinguish the fire, or to slow down the spread of the fire.

[0144] In accordance with the above embodiment, please refer to Figure 4 , Figure 4: is a structural schematic diagram of an electronic device provided by an embodiment of the present application, which is applied to a fire management system, wherein the fire management system includes a fire main warehouse and multiple battery clusters, the fire main warehouse includes a fire host, a fire cylinder and a main solenoid valve corresponding to the fire cylinder, the fire main warehouse is connected to multiple battery compartments, the volume of the fire cylinder is related to the number of the multiple battery compartments, each of the battery compartments is provided with a sub-solenoid valve, the fire host is used to locate the position of each battery compartment and control the battery compartment individually; the battery compartment includes multiple battery clusters and detectors composed of battery modules; Figure 4 As shown, the electronic device includes a processor, a memory, a communication interface, and one or more programs.

[0145] Optionally, when applied to a fire host included in a fire warehouse of a fire management system, the one or more programs are stored in the memory and configured to be executed by the processor, and the program includes instructions for executing the following steps:

[0146] receiving a fire alarm signal sent by a target battery compartment, wherein the target battery compartment is any one of the multiple battery compartments;

[0147] In response to the fire alarm signal, acquiring location information of the target battery compartment;

[0148] Based on the position information, the main solenoid valve and the sub-solenoid valve corresponding to the target battery compartment are controlled to open, and the sub-solenoid valve corresponding to the target battery compartment is controlled to spray a gas fire-fighting medium with a preset fire-extinguishing concentration dose.

[0149] In one possible example, in terms of controlling the sub-solenoid valve corresponding to the target battery compartment to spray the gas firefighting medium, the above program includes instructions for executing the following steps:

[0150] Determine the distance between the target battery compartment and the fire fighting main warehouse;

[0151] If the distance is greater than a preset threshold, a centrifugal pump or an air compressor is controlled to perform secondary pressurization on the gas fire fighting medium, and the number of spraying times for the target battery compartment is determined;

[0152] Based on the spraying times, the sub-solenoid valve corresponding to the target battery compartment is controlled to spray the gas fire fighting medium.

[0153] In a possible example, the program further includes instructions for executing the following steps:

[0154] If multiple fire alarm signals are received from multiple target battery compartments, and the number of the target battery compartments is greater than the first preset protection number, the intelligent polling spraying mode is started, and each target battery compartment corresponds to a fire alarm signal.

[0155] In a possible example, in the intelligent polling spraying mode, the program further includes instructions for executing the following steps:

[0156] Obtaining target evaluation parameters carried by the fire alarm signal of each target battery compartment;

[0157] Evaluate the danger level of each target battery compartment according to the target evaluation parameter;

[0158] sorting the plurality of target battery compartments according to the degree of danger;

[0159] According to the order of the multiple target battery compartments, the corresponding solenoid valves of each target battery compartment are controlled in sequence from large to small to spray the gas fire-fighting medium with the preset fire-extinguishing concentration dosage, and in this process, the fire alarm signal is polled to spray the gas fire-fighting medium in a targeted manner.

[0160] It can be seen that the electronic device described in the embodiment of the present application receives the fire alarm signal sent by the target battery compartment, and the target battery compartment is any one of the multiple battery compartments; in response to the fire alarm signal, obtains the location information of the target battery compartment; based on the location information, controls the main solenoid valve and the sub-solenoid valve corresponding to the target battery compartment to open, and controls the sub-solenoid valve corresponding to the target battery compartment to spray the gas fire-fighting medium with a preset fire-extinguishing concentration. In this way, the fire alarm signal sent by the target battery compartment can be received, and the main solenoid valve of the fire-fighting gas cylinder can be opened, and the sub-solenoid valve of the target battery compartment can be opened at the same time. The volume of the fire-fighting gas cylinder is related to the number of multiple battery compartments, and all fire-fighting media can be concentrated to spray the target battery compartment to achieve targeted and efficient fire extinguishing, which is conducive to improving the fire-fighting effect.

[0161] Optionally, when applied to a detector included in any battery compartment of a fire management system, the one or more programs are stored in the memory and configured to be executed by the processor, and the program includes instructions for executing the following steps:

[0162] Obtaining evaluation parameters of each battery cluster, and determining a warning level of each battery cluster according to a preset fire warning threshold corresponding to each evaluation parameter;

[0163] Determine that the battery cluster whose warning level reaches the highest warning level is the target battery cluster, and the battery compartment is the target battery compartment, and send a fire alarm signal to the fire host in the fire main warehouse, the fire alarm signal is used to request the spraying of a gas fire fighting medium with a preset fire extinguishing concentration, and the fire alarm signal carries the location information of the target battery compartment and / or the location information of the target battery cluster, as well as the target evaluation parameters corresponding to the highest warning level;

[0164] According to the evaluation parameters of each battery cluster and the corresponding preset fire warning threshold, the relevant devices in the battery compartment are controlled to perform corresponding operations under different warning levels.

[0165] In one possible example, the above program includes instructions for executing the following steps:

[0166] If the warning level of each battery cluster does not reach the highest warning level, the evaluation parameters of each battery cluster are monitored by polling, so that after the target battery cluster is determined, the fire alarm signal is sent to the fire host through the detector.

[0167] In a possible example, in terms of determining the warning level of each battery cluster according to the preset fire warning threshold corresponding to each evaluation parameter, the program includes instructions for executing the following steps:

[0168] If the temperature of any of the evaluation parameters monitored for the battery cluster is greater than or equal to a first preset temperature threshold and less than a second preset temperature threshold, and / or the carbon monoxide concentration is greater than or equal to a first preset carbon monoxide concentration threshold and less than a second preset carbon monoxide concentration threshold, and / or the electrolyte concentration is greater than or equal to a preset electrolyte concentration threshold, it is determined that the battery cluster is at a secondary warning level.
