Description

Technical Field

[0001] The present application relates to the field of fire protection, and specifically to a fire protection device, system, fire protection control method, equipment and storage medium. Background Art

[0002] Lithium-ion batteries have the advantages of large capacity, high operating voltage, long cycle life, small size, and light weight, and can be used in many scenarios. In electric vehicles and energy storage systems, the power battery of the power source is required to have a large capacity and voltage, which requires multiple single cells to be placed in a battery box and connected in series and parallel to form a battery pack. Multiple battery boxes are combined to form an energy storage power station.

[0003] In the related art, each battery cell in the battery box is connected to a thermistor. When the thermistor detects that the temperature of the battery cell exceeds a preset value, the fire extinguishing unit is triggered to start. However, once the thermistor fails or the control device that triggers the fire extinguishing unit fails, the fire cannot be extinguished, which seriously affects the safe operation of the energy storage power station.

[0004] The above statements are only used to provide background information related to the present application and do not necessarily constitute prior art. Summary of the invention

[0005] In view of the above problems, the embodiments of the present application provide a fire-fighting device, system, fire-fighting control method, equipment and storage medium, which can alleviate the problem in the related art that once the thermistor fails or the control device that controls the triggering of the fire-fighting unit fails, fire-fighting cannot be implemented, seriously affecting the safe operation of the energy storage power station.

[0006] A first aspect provides a fire fighting device, comprising:

[0007] Fire control equipment, fire extinguishing equipment, power supply equipment, primary detection equipment and secondary detection equipment;

[0008] The fire control device is connected to the first detection device and the fire extinguishing device respectively;

[0009] The fire extinguishing device is also connected to the power supply device and the second detection device; the second detection device is also connected to the power supply device.

[0010] In the solution provided in this embodiment, the fire-fighting device has two fire-fighting channels for triggering the activation of the fire-fighting equipment, which are respectively a fire-fighting channel formed by the fire-fighting control device and the first detection device, and a fire-fighting channel formed by the power supply device and the second detection device. The two fire-fighting channels are backup for each other. When one fire-fighting channel fails and cannot trigger the activation of the fire-fighting equipment, the activation of the fire-fighting equipment can also be triggered through the other fire-fighting channel, which greatly improves the fire-fighting reliability of the fire-fighting device.

[0011] In some embodiments, it also includes:

[0012] an addressing module connected to at least one of the fire control device and the fire extinguishing device;

[0013] In the case where the addressing module is connected to the fire control device, the addressing module is used to respond to the thermal runaway signal of the fire control device and send a thermal runaway signal carrying the address of the fire control device to the outside of the fire device;

[0014] When the addressing module is connected to the fire extinguishing equipment, the addressing module is used to respond to the fire extinguishing feedback signal of the fire extinguishing equipment and send a fire extinguishing feedback signal carrying the address of the fire extinguishing equipment to the outside of the fire fighting device.

[0015] In the solution provided in this embodiment, an addressing module is set in the fire-fighting device, so that the outside of the fire-fighting device can distinguish which fire-fighting device the thermal runaway signal comes from, and distinguish which fire-fighting device's fire-fighting equipment is triggered, which helps to locate the object where the fire occurs.

[0016] In some embodiments, the first detection device includes at least two of a temperature sensor, a smoke sensor, and a combustible gas sensor.

[0017] In the solution provided in this embodiment, the first detection device includes at least two sensors. The degree of thermal runaway detected by at least two sensors is more accurate, which helps the fire control equipment to accurately determine the timing to trigger the fire extinguishing equipment to start, and reduce the occurrence of false fire triggering.

[0018] In some embodiments, the second detection device includes at least one of a temperature sensor, a smoke sensor, and a combustible gas sensor.

[0019] In the solution provided in this embodiment, the second detection device includes at least one sensor, and the degree of thermal runaway detected by the at least one sensor is more accurate.

[0020] In a second aspect, a fire fighting system is provided, comprising:

[0021] An energy storage cabinet and the fire-fighting device described in the first aspect;

[0022] The energy storage cabinet is connected to the fire-fighting device.

[0023] In the solution provided in this embodiment, when thermal runaway occurs in the battery in the energy storage cabinet, the fire fighting device is used to fight the fire, which can improve the reliability of fire fighting.

[0024] In some embodiments, the fire-fighting device is disposed in the energy storage cabinet.

[0025] In the solution provided in this embodiment, each energy storage cabinet is equipped with a set of fire-fighting equipment, which can reduce the mutual influence and poor reliability problems existing in the fire-fighting equipment shared by the energy storage cabinets.

[0026] In some embodiments, the fire control device and the power supply device included in the fire fighting device are both arranged outside the energy storage cabinet;

[0027] The fire extinguishing equipment, the first detection equipment and the second detection equipment included in the fire fighting device are arranged in the energy storage cabinet.

[0028] In the solution provided in this embodiment, the fire control equipment and the power supply equipment are arranged outside the fire protection device. In this way, when there are multiple energy storage cabinets, multiple energy storage cabinets can share the same fire control equipment and power supply equipment, which helps to reduce equipment costs.

[0029] In some embodiments, it also includes:

[0030] an alarm device connected to the fire control device;

[0031] The alarm device is arranged outside the energy storage cabinet.

[0032] In the solution provided in this embodiment, an alarm device is provided in the fire protection system, which helps users to know the current fire as soon as possible so that measures can be taken to reduce property losses.

[0033] In some embodiments, it also includes:

[0034] Isolating switch;

[0035] One end of the isolating switch is connected to the fire control equipment;

[0036] The other end of the isolation switch is connected to at least one of the alarm device, the fire extinguishing device and the first detection device.

[0037] In the solution provided in this embodiment, an isolating switch is provided to help reduce the impact of the short-circuit current on the fire control equipment when a short circuit occurs in the alarm equipment, the fire extinguishing equipment or the first detection equipment.

[0038] In some embodiments, it also includes:

[0039] a display device connected to the fire control device;

[0040] The display device is arranged outside the energy storage cabinet.

[0041] The solution provided in this embodiment is to set a display device in the fire protection system, and the thermal runaway signal of the fire control equipment can be displayed through the display device, which helps the user understand the extent of thermal runaway.

[0042] In a third aspect, a fire control method is provided, which is applied to the fire protection system according to the second aspect, and the method comprises:

[0043] Detecting environmental parameters in the energy storage cabinet, where the environmental parameters are used to characterize the degree of thermal runaway of the energy storage device in the energy storage cabinet, and the environmental parameters include a first environmental parameter detected by the first detection device and a second environmental parameter detected by the second detection device;

[0044] When at least two of the first environmental parameters satisfy a fire extinguishing condition and the second environmental parameter satisfies a fire extinguishing condition, the fire extinguishing equipment is started.

[0045] In the solution provided in this embodiment, both the first environmental parameter and the second environmental parameter may meet the fire extinguishing conditions, and when the fire extinguishing conditions are met, the fire extinguishing equipment can be triggered to start. This logic of judging the triggering of the start of the fire extinguishing equipment improves the reliability of fire extinguishing.

[0046] In some embodiments, it also includes:

[0047] Based on the fact that the second environmental parameter is greater than a parameter threshold and the connection between the fire control device and the fire extinguishing device is disconnected, it is determined that the second environmental parameter satisfies the fire extinguishing condition.

[0048] In the solution provided in this embodiment, when the parameter threshold for determining the second environmental parameter is relatively close to the parameter threshold for determining the first environmental parameter, the on-off connection judgment between the fire control device and the fire extinguishing device can be used to reduce the occurrence of the second detection device erroneously triggering the start of the fire extinguishing device.

[0049] In some embodiments, a parameter threshold used to determine whether the first detection device is triggered is lower than a parameter threshold used to determine whether the second detection device is triggered.

[0050] In the solution provided in this embodiment, setting the parameter threshold for triggering the first detection device to be lower than the parameter threshold for triggering the second detection device helps to preferentially trigger the start of the fire extinguishing device through the fire control device with higher accuracy, thereby improving the reliability of fire fighting.

[0051] In some embodiments, the fire protection system further includes an addressing module and a display device; the method further includes:

[0052] When the first environmental parameter satisfies the fire extinguishing condition, a secondary fire alarm signal is sent to the battery management system, and a secondary fire alarm signal carrying the address of the fire fighting device is sent to the display device through the addressing module.

[0053] In the solution provided by this embodiment, sending a secondary fire alarm signal to the battery management system helps the battery point management system to control the operating status of the battery in the energy storage cabinet. For example, the battery management system can suspend the operation of the battery to reduce the heat generated by the battery and cool the battery from the perspective of battery operation. Sending a secondary fire alarm signal with the address of the fire-fighting device to the display device helps the staff understand which energy storage cabinet has a fire and the extent of thermal runaway of the battery in the energy storage cabinet.

[0054] In some embodiments, the method further comprises:

[0055] When one of the first environmental parameters meets the preset abnormal condition, a first-level fire alarm signal is sent to the battery management system, and a first-level fire alarm signal carrying the address of the fire-fighting device is sent to the display device through the addressing module.

[0056] In the solution provided by this embodiment, sending a first-level fire alarm signal to the battery management system helps the battery point management system to control the operating status of the battery in the energy storage cabinet. For example, the battery management system can make the battery run at a lower power to reduce the heat generated by the battery and cool the battery from the perspective of battery operation. Sending a first-level fire alarm signal with the address of the fire-fighting device to the display device helps the staff understand which energy storage cabinet has a fire and the extent of thermal runaway of the battery in the energy storage cabinet.

[0057] In some embodiments, the method further comprises:

[0058] When the fire extinguishing equipment sprays the fire extinguishing substance, a fire extinguishing feedback signal carrying the address of the fire fighting device is sent to the battery management system through the addressing module.

[0059] In the solution provided in this embodiment, sending a fire extinguishing feedback signal carrying a fire address to the battery management system helps the battery management system understand which fire extinguishing device 12 in the energy storage cabinet is activated, so as to monitor and adjust the operating status of the battery.

[0060] In some embodiments, the fire protection system further includes an alarm device; and the method further includes:

[0061] When at least two of the first environmental parameters satisfy the fire extinguishing condition and the second environmental parameter satisfies any one of the fire extinguishing conditions, controlling the alarm device to continuously alarm;

[0062] When one of the first environmental parameters meets a preset abnormal condition, the alarm device is controlled to issue an alarm for a preset duration.

[0063] The solution provided by this embodiment is that at least two of the first environmental parameters meet the fire extinguishing conditions and the second environmental parameter meets any one of the fire extinguishing conditions, indicating that a serious fire has occurred in the energy storage cabinet that requires the activation of the fire extinguishing device 12. In this case, by controlling the alarm device to continuously alarm, the staff can be informed as soon as possible that a fire has occurred in the energy storage cabinet. One of the first environmental parameters meets the preset abnormal condition, indicating that a minor fire has occurred in the energy storage cabinet. By feedback to the battery management system and the battery management system controlling and adjusting the operating status of the battery, the thermal runaway in the energy storage cabinet is very likely to be alleviated. In this case, the alarm device's alarm for a preset duration can not only serve as a warning, but also reduce energy consumption.

[0064] In a fourth aspect, a fire control device is provided, which is applied to the fire protection system according to the second aspect, and the device comprises:

[0065] A monitoring module, used to detect environmental parameters in the energy storage cabinet, wherein the environmental parameters are used to characterize the degree of thermal runaway of the energy storage device in the energy storage cabinet, and the environmental parameters include a first environmental parameter detected by the first detection device and a second environmental parameter detected by the second detection device;

[0066] A starting module is used to start the fire extinguishing equipment when at least two of the first environmental parameters meet the fire extinguishing conditions and the second environmental parameter meets the fire extinguishing conditions.

[0067] In a fifth aspect, an electronic device is provided, comprising: a processor and a memory;

[0068] The memory is used to store computer programs;

[0069] The processor is used to execute the program stored in the memory to implement the fire control method described in the third aspect.

[0070] In a sixth aspect, a computer-readable storage medium is provided, storing a computer program, wherein the computer program, when executed by a processor, implements the fire control method described in the third aspect.

[0088] Lithium-ion batteries have the advantages of large capacity, high operating voltage, long cycle life, small size, and light weight, and can be used in many scenarios. In electric vehicles and energy storage systems, the power battery of the power source is required to have a large capacity and voltage, which requires multiple single cells to be placed in a battery box and connected in series and parallel to form a battery pack. Multiple battery boxes are combined to form an energy storage power station.

[0089] In the related art, each battery cell in the battery box is connected to a thermistor. When the thermistor detects that the temperature of the battery cell exceeds a preset value, the fire extinguishing unit is triggered to start. However, once the thermistor fails or the control device that triggers the fire extinguishing unit fails, the fire cannot be extinguished, which seriously affects the safe operation of the energy storage power station.

[0090] In order to alleviate the problems existing in the related art, the present application provides a fire-fighting device, a system, a control method, a device and a storage medium. The fire-fighting device includes a fire-fighting control device, a fire-fighting device, a power supply device, a first detection device and a second detection device; the fire-fighting control device is connected to the first detection device and the fire-fighting device respectively; the fire-fighting device is also connected to the power supply device and the second detection device; the second detection device is also connected to the power supply device. The fire-fighting device has two fire-fighting channels that trigger the activation of the fire-fighting device, which are the fire-fighting channels formed by the fire-fighting control device and the first detection device, and the fire-fighting channels formed by the power supply device and the second detection device. The two fire-fighting channels are backup for each other. When one fire-fighting channel fails and cannot trigger the activation of the fire-fighting device, the activation of the fire-fighting device can also be triggered through another fire-fighting channel, which greatly improves the fire-fighting reliability of the fire-fighting device.

[0091] The fire-fighting device in the embodiments of the present application includes, but is not limited to, applications in energy storage cabinets, factory workshops, high-voltage electrical equipment, and the like.

[0092] The batteries in the energy storage cabinet of the embodiment of the present application include but are not limited to lithium-ion batteries, lithium metal batteries, lead-acid batteries, nickel-cathode batteries, nickel-hydrogen batteries, lithium-sulfur batteries, lithium-air batteries or sodium-ion batteries, etc. The scale of the battery may include but is not limited to single cells, battery modules or battery packs, etc. It should be understood that the batteries in the embodiment of the present application can be batteries with low battery energy used in smart home devices, terminal devices, etc., or power batteries with high battery energy used in energy storage power supply systems, electric vehicles, etc.

[0093] See also Figure 1 , Figure 1 A fire fighting device is shown in an embodiment of the present application, and the device may include:

[0094] Fire control equipment 11, fire extinguishing equipment 12, power supply equipment 13, first detection equipment 14 and second detection equipment 15;

[0095] The fire control device 11 is connected to the first detection device 14 and the fire extinguishing device 12 respectively;

[0096] The fire extinguishing device 12 is also connected to the power supply device 13 and the second detection device 15 ; the second detection device 15 is also connected to the power supply device 13 .

[0097] In this embodiment, the fire extinguishing device 12 is a device capable of spraying fire extinguishing substances. The fire extinguishing substances sprayed by the fire extinguishing device 12 include but are not limited to aerosols, carbon dioxide, water, and the like.

[0098] In this embodiment, in addition to the interaction of control commands between the fire control device 11 and the first detection device 14 and the fire extinguishing device 12, the fire control device 11 is also used to supply power to the first detection device 14 and the fire extinguishing device 12. In practical applications, a power line compatible with signal transmission can be used to connect the fire control device 11 and the first detection device 14, and a power line compatible with signal transmission can be used to connect the fire control device 11 and the fire extinguishing device 12. Through the power line compatible with signal transmission, the fire control device 11 can supply power to the first detection device 14 and the fire extinguishing device 12, and can also realize signal transmission between the fire control room equipment and the first detection device 14 and the fire extinguishing device 12, such as the fire control device 11 controls the start-up of the fire extinguishing device 12.

[0099] In this embodiment, the power supply device 13 includes but is not limited to an independent network power box, and the power supply device 13 can supply power to the fire extinguishing device 12 and the second detection device 15 separately. In this way, when the fire control device 11 fails or the first detection device 14 fails, the fire extinguishing device 12 can also be triggered to start by the second detection device 15.

[0100] In the solution provided in this embodiment, the fire-fighting device has two fire-fighting channels for triggering the activation of the fire-fighting equipment, which are respectively a fire-fighting channel formed by the fire-fighting control device and the first detection device, and a fire-fighting channel formed by the power supply device and the second detection device. The two fire-fighting channels are backup for each other. When one fire-fighting channel fails and cannot trigger the activation of the fire-fighting equipment, the activation of the fire-fighting equipment can also be triggered through the other fire-fighting channel, which greatly improves the fire-fighting reliability of the fire-fighting device.

[0101] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0102] In one or more embodiments of the present application, Figure 2 As shown, the fire fighting device may also include:

[0103] an addressing module 1616 connected to at least one of the fire control device 11 and the fire extinguishing device 12;

[0104] When the addressing module 16 is connected to the fire control device 11, the addressing module 16 is used to respond to the thermal runaway signal of the fire control device 11 and send a thermal runaway signal carrying the address of the fire control device to the outside of the fire device;

[0105] When the addressing module 16 is connected to the fire extinguishing device 12 , the addressing module 16 is used to respond to the fire extinguishing feedback signal of the fire extinguishing device 12 and send a fire extinguishing feedback signal carrying the address of the fire extinguishing device to the outside of the fire extinguishing device.

[0106] In this embodiment, the thermal runaway signal is used to characterize the degree of thermal runaway. In practical applications, different levels or priorities can be used to distinguish thermal runaway signals that characterize different degrees of thermal runaway. For example, compared with the first level thermal runaway signal, the second level thermal runaway signal characterizes a more serious degree of thermal runaway.

[0107] In this embodiment, the addressing module 16 stores the address of the fire-fighting device. For the thermal runaway signal and / or fire-extinguishing feedback signal input into the addressing module 16, the addressing module 16 can add the address of the fire-fighting device to the thermal runaway signal and / or the fire-fighting feedback signal, and send the thermal runaway signal carrying the address and / or the fire-fighting feedback signal carrying the address to the outside of the fire-fighting device.

[0108] In this embodiment, the address of the fire-fighting device can be specifically represented by a code stored in the addressing module 16 or by a module identifier of the addressing module 16. In this case, the addressing modules 16 provided in different fire-fighting devices store different codes, or the module identifiers of the addressing modules 16 provided in different fire-fighting devices are different.

[0109] In the case where a plurality of addressing modules 16 are provided in the fire-fighting device, the codes stored in each addressing module 16 can represent the address of the fire-fighting device, or the module identification of each storage module can represent the address of the fire-fighting device. In one example, the fire-fighting device is provided with one addressing module 16, and the code of the addressing module 16 is 1, then 1 can be used as the address of the fire-fighting device. In another example, the fire-fighting device is provided with two addressing modules 16, and the codes of the two addressing modules 16 are 1 and 2 respectively, then 1 and 2 can both be used as the address of the fire-fighting device to uniquely refer to a fire-fighting device.

[0110] In this embodiment, when the fire control device 11 may generate multiple thermal runaway signals and the degrees of thermal runaway represented by the multiple thermal runaway signals are different from each other, multiple addressing modules 16 can be set in the fire protection device to distinguish the multiple thermal runaway signals through the coding in the addressing module 16 or the identification of the addressing module 16.

[0111] In an example, the fire control device 11 may generate a first thermal runaway signal and a second thermal runaway signal. The fire control device 11 is connected to the first addressing module and the second addressing module respectively, and the fire control device 11 sends the first thermal runaway signal to the first addressing module and sends the second thermal runaway signal to the second addressing module. The first addressing module adds the code 1 of the first addressing module to the first thermal runaway signal, and the second addressing module adds the code 2 of the second addressing module to the second thermal runaway signal. In this way, when the first thermal runaway signal with the added code 1 and the second thermal runaway signal with the added code 2 are sent to the outside of the fire protection device, the outside of the fire protection device can distinguish whether the received thermal runaway signal is the first thermal runaway signal or the second thermal runaway signal based on the codes 1 and 2 in the thermal runaway signal.

[0112] It should be understood that the external storage of the fire-fighting device has a correspondence between codes and thermal runaway signals. Therefore, after receiving a thermal runaway signal, the correspondence can be queried using the code carried in the received thermal runaway signal to determine whether the received thermal runaway signal is the first thermal runaway signal or the second thermal runaway signal.

[0113] In this embodiment, the fire extinguishing feedback signal is a signal generated after the fire extinguishing equipment 12 sprays the fire extinguishing substance.

[0114] In the solution provided in this embodiment, an addressing module is set in the fire-fighting device, so that the outside of the fire-fighting device can distinguish which fire-fighting device the thermal runaway signal comes from, and distinguish which fire-fighting device's fire-fighting equipment is triggered, which helps to locate the object where the fire occurs.

The degree of thermal runaway detected by at least two sensors is more accurate, which helps the fire control equipment to accurately determine the timing to trigger the fire extinguishing equipment to start, and reduce the occurrence of false fire triggering.

[0128] In the solution provided in this embodiment, each energy storage cabinet is equipped with a set of fire-fighting equipment, which can reduce the mutual influence and poor reliability problems existing in the fire-fighting equipment shared by the energy storage cabinets.

[0129] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0130] In one or more embodiments of the present application, the fire control device 11 and the power supply device 13 included in the fire fighting device 32 are both arranged outside the energy storage cabinet 31;

[0131] The fire-fighting device 32 includes a fire-extinguishing device 12 , a first detection device 14 and a second detection device 15 which are arranged in the energy storage cabinet 31 .

[0132] It should be understood that the fire control device and the power supply device are arranged outside the fire protection device, so that when there are multiple energy storage cabinets, multiple energy storage cabinets can share the same fire control device and power supply device.

[0133] In this embodiment, the first detection device has its own addressing function, that is, the signal sent by the first detection device to the fire control device carries the address of the first detection device. At the same time, the fire control device stores the address of the first detection device in each energy storage cabinet. In this way, in the case of multiple energy storage cabinets, after receiving the signal from the first detection device, the fire control device can determine, based on the address in the signal, which energy storage cabinet the signal comes from.

[0134] It should be understood that, in addition to using its own addressing function for addressing, the first detection device can also be addressed with the help of the addressing module involved in the embodiments of the present application.

[0135] In this embodiment, the fire extinguishing device may also have its own addressing function, so that the fire extinguishing feedback signal of the fire extinguishing device can address the fire extinguishing feedback signal through the fire extinguishing device's own addressing function, so that the fire extinguishing feedback signal carries the address of the fire-fighting device.

[0136] In the solution provided in this embodiment, the fire control equipment and the power supply equipment are arranged outside the fire protection device. In this way, when there are multiple energy storage cabinets, multiple energy storage cabinets can share the same fire control equipment and power supply equipment, which helps to reduce equipment costs.

[0137] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0138] In one or more embodiments of the present application, the fire protection system further includes:

[0139] An alarm device connected to the fire control device 11;

[0140] The alarm device is arranged outside the energy storage cabinet 31 .

[0141] Among them, the alarm equipment includes but is not limited to sound and light alarms.

[0142] In the solution provided in this embodiment, an alarm device is provided in the fire protection system, which helps users to know the current fire as soon as possible so that measures can be taken to reduce property losses.

[0143] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0144] In one or more embodiments of the present application, the fire protection system further includes:

[0145] Isolating switch;

[0146] One end of the isolating switch is connected to the fire control device 11;

[0147] The other end of the isolation switch is connected to at least one of the alarm device, the fire extinguishing device 12 and the first detection device 14 .

[0148] It should be understood that when a short circuit occurs in the alarm device, the fire extinguishing device 12 or the first detection device 14 , the isolation switch is opened, which can alleviate the impact of the short circuit current on the fire control device 11 .

[0149] In applications, when there are multiple energy storage cabinets, in order to reduce the cost of equipment, the multiple energy storage cabinets can be divided into multiple groups, and each group of energy storage cabinets shares an isolating switch, which is arranged between the fire control device 11 and the common input terminal of each group of energy storage cabinets connected in parallel.

[0150] In the solution provided in this embodiment, an isolating switch is provided to help reduce the impact of the short-circuit current on the fire control equipment when a short circuit occurs in the alarm equipment, the fire extinguishing equipment or the first detection equipment.

[0151] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0152] In one or more embodiments of the present application, the fire protection system further includes:

[0153] A display device connected to the fire control device 11;

[0154] The display device is arranged outside the energy storage cabinet.

[0155] The solution provided in this embodiment is to set a display device in the fire protection system, and the thermal runaway signal of the fire control equipment can be displayed through the display device, which helps the user understand the extent of thermal runaway.

[0156] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0157] The present application also provides a fire control method, which can be applied to the above fire protection system. Figure 4 As shown, the method may include the following steps:

[0158] Step 401: Detect environmental parameters in the energy storage cabinet, where the environmental parameters are used to characterize the degree of thermal runaway of the energy storage device in the energy storage cabinet, and the environmental parameters include a first environmental parameter detected by a first detection device and a second environmental parameter detected by a second detection device;

[0159] Step 402: Start the fire extinguishing equipment when at least two of the first environmental parameters satisfy the fire extinguishing conditions and the second environmental parameter satisfies any one of the fire extinguishing conditions.

[0160] Among them, at least two environmental parameters in the first environmental parameters meet the fire extinguishing conditions, indicating that the sensors detecting at least two environmental parameters are triggered, that is, at least two environmental parameters are greater than the parameter threshold.

[0161] In this embodiment, when the parameter threshold for determining the second environmental parameter differs greatly from the parameter threshold for determining the first environmental parameter, whether the second environmental parameter meets the fire extinguishing condition can be determined directly based on whether the second environmental parameter is greater than the parameter threshold.

[0162] In this embodiment, the parameter thresholds for determining the first environmental parameter and the second environmental parameter can be preset manually based on experience or according to actual needs. It should be understood that, whether it is the first environmental parameter or the second environmental parameter, different types of environmental parameters may correspond to different parameter thresholds.

[0163] In the application, the thermal runaway of the battery in the energy storage cabinet usually has the following four stages: in the first stage, the battery heats up and reaches the first temperature; in the second stage, the battery produces flammable gas, and the temperature of the battery rises from the first temperature to the second temperature; in the third stage, the battery undergoes severe thermal runaway, produces smoke and the temperature rises from the second temperature to the third temperature; in the fourth stage, the flammable gas produced by the battery burns to produce an open flame, and the temperature continues to rise from the third temperature to the fourth temperature. In the related art, a temperature sensor is used to monitor the degree of thermal runaway of the battery, and the temperature collected by the temperature sensor is used as a factor to determine whether the fire extinguishing device 12 is activated. Therefore, the fire extinguishing device 12 is often triggered to start before the battery produces an open flame, but the fire cannot be extinguished after the battery produces an open flame. In this embodiment, the fire control device 11 starts the fire extinguishing device 12 only when at least two environmental parameters in the first environmental parameters meet the fire extinguishing conditions. Compared with the related art that only uses one sensor parameter as a condition for determining whether to start the fire extinguishing device 12, the accuracy of the time to trigger the start of the fire extinguishing device 12 can be greatly improved.

[0164] In the solution provided in this embodiment, both the first environmental parameter and the second environmental parameter may meet the fire extinguishing conditions, and when the fire extinguishing conditions are met, the fire extinguishing equipment can be triggered to start. This logic of judging the triggering of the start of the fire extinguishing equipment improves the reliability of fire extinguishing.

[0165] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0166] In one or more embodiments of the present application, the method further includes:

[0167] Based on the second environmental parameter being greater than the parameter threshold and the connection between the fire control device and the fire extinguishing device being disconnected, it is determined that the second environmental parameter satisfies the fire extinguishing condition.

[0168] In this embodiment, the fire control device 11 triggers the start of the fire extinguishing device 12 by sending an electrical signal to the fire extinguishing device 12. The electrical signal is controlled by a normally closed switch controlled by the fire control device 11. When the fire control device 11 fails, the normally closed switch pops open, and the fire extinguishing device 12 cannot receive the electrical signal from the fire control device. The fire extinguishing module determines that the fire control device 11 has failed.

[0169] In the solution provided in this embodiment, when the parameter threshold for determining the second environmental parameter is relatively close to the parameter threshold for determining the first environmental parameter, the on-off connection judgment between the fire control device and the fire extinguishing device can be used to reduce the occurrence of the second detection device erroneously triggering the start of the fire extinguishing device.

[0170] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0171] In one or more embodiments of the present application, a parameter threshold for determining whether the first detection device is triggered is smaller than a parameter threshold for determining whether the second detection device is triggered.

[0172] It should be understood that since the parameter threshold for determining that the first detection device 14 is triggered is lower than the parameter threshold for determining that the second detection device 15 is triggered, in the event of thermal runaway of the energy storage cabinet, the fire control device 11 first triggers the fire extinguishing device 12 to start. If the fire control device 11 cannot trigger the fire extinguishing device 12 to start, the fire extinguishing device 12 is started through the second detection device 15.

[0173] In the solution provided in this embodiment, setting the parameter threshold for triggering the first detection device to be lower than the parameter threshold for triggering the second detection device helps to preferentially trigger the start of the fire extinguishing device through the fire control device with higher accuracy, thereby improving the reliability of fire fighting.

[0174] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0175] In one or more embodiments of the present application, the fire protection system further includes an addressing module 16 and a display device; the method further includes:

[0176] When the first environmental parameter meets the fire extinguishing condition, a secondary fire alarm signal is sent to the battery management system, and the secondary fire alarm signal carrying the address of the fire fighting device is sent to the display device through the addressing module 16.

[0177] In the solution provided by this embodiment, sending a secondary fire alarm signal to the battery management system helps the battery point management system to control the operating status of the battery in the energy storage cabinet. For example, the battery management system can suspend the operation of the battery to reduce the heat generated by the battery and cool the battery from the perspective of battery operation. Sending a secondary fire alarm signal with the address of the fire-fighting device to the display device helps the staff understand which energy storage cabinet has a fire and the extent of thermal runaway of the battery in the energy storage cabinet.

[0178] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0179] In one or more embodiments of the present application, the method further includes:

[0180] When one of the first environmental parameters meets the preset abnormal condition, a first-level fire alarm signal is sent to the battery management system, and a first-level fire alarm signal carrying the address of the fire-fighting device is sent to the display device through the addressing module 16.

[0181] Among them, one of the first environmental parameters meets the preset abnormal condition, which indicates that the sensor corresponding to the one environmental parameter is triggered, that is, the one environmental parameter is greater than the parameter threshold.

[0182] It should be understood that the level 1 fire alarm signal indicates that the degree of thermal runaway of the battery is lower than the level 2 fire alarm signal indicates that the degree of thermal runaway of the battery is lower.

[0183] In the solution provided by this embodiment, sending a first-level fire alarm signal to the battery management system helps the battery point management system to control the operating status of the battery in the energy storage cabinet. For example, the battery management system can make the battery run at a lower power to reduce the heat generated by the battery and cool the battery from the perspective of battery operation. Sending a first-level fire alarm signal with the address of the fire-fighting device to the display device helps the staff understand which energy storage cabinet has a fire and the extent of thermal runaway of the battery in the energy storage cabinet.

[0184] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0185] In one or more embodiments of the present application, the method further includes:

[0186] When the fire extinguishing device 12 releases fire extinguishing substances, a fire extinguishing feedback signal carrying the address of the fire fighting device is sent to the battery management system through the addressing module 16 .

[0187] In the solution provided in this embodiment, sending a fire extinguishing feedback signal carrying a fire address to the battery management system helps the battery management system understand which fire extinguishing device 12 in the energy storage cabinet is activated, so as to monitor and adjust the operating status of the battery.

[0188] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0189] In one or more embodiments of the present application, the fire protection system further includes an alarm device; and the method further includes:

[0190] When at least two of the first environmental parameters satisfy the fire extinguishing condition and the second environmental parameter satisfies any one of the fire extinguishing conditions, the alarm device is controlled to continuously alarm;

[0191] When one of the first environmental parameters meets a preset abnormal condition, the alarm device is controlled to sound an alarm for a preset duration.

[0192] At least two of the first environmental parameters meet the fire extinguishing conditions and the second environmental parameter meets any one of the fire extinguishing conditions, indicating that a serious fire has occurred in the energy storage cabinet that requires the activation of the fire extinguishing device 12. In this case, by controlling the alarm device to continuously alarm, the staff can be informed as soon as possible that a fire has occurred in the energy storage cabinet. One of the first environmental parameters meets the preset abnormal condition, indicating that a minor fire has occurred in the energy storage cabinet. By feedback to the battery management system and the battery management system controlling and adjusting the operating status of the battery, the thermal runaway in the energy storage cabinet is very likely to be alleviated. In this case, the alarm device's alarm for a preset duration can not only serve as a warning, but also reduce energy consumption.
