[0065] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0066] Before describing a fire extinguishing device and a power distribution cabinet provided by the present application, relevant content of fires will be briefly described first.

[0067] When a substance is subjected to abnormal heat and the degree of heat absorption exceeds the ultimate tolerance of the substance, the particles released by the substance in this heat-absorbed state are usually unstable microscopic particles, that is, thermally released particles, also called thermally released ions, pyrolysis particles, etc. Then, the charged particles released by the substance due to pyrolysis can be called thermally released particles.

[0068] Correspondingly, the essence of a fire is combustion. Before the temperature of a combustible substance reaches the ignition point during the slow combustion process, there is an electron escape phenomenon, releasing a large number of thermally released particles. As the temperature rises, it begins to carbonize and then reaches the ignition point to start ignition. For example, Figure 1AAs shown, it is a schematic diagram of the four stages of combustion, and as Figure 1B shown, in the traditional technology, it is the fire detection system corresponding to each stage of combustion. Among them, Figure 1A and Figure 1B in the coordinate system, the horizontal axis is time, with the unit of second (s), and the vertical axis is temperature, with the unit of degree Celsius (°C). And Figure 1A and Figure 1B the curves in it can reflect the change of ambient temperature with time as the fire develops.

[0069] 1) The first stage is the melting and depolymerization stage. In this stage, according to the combustion chain reaction theory of H. H. Semenov, when the combustible material is heated to the heat loss value, melting and depolymerization will occur, thereby generating free radicals, that is, heat release particles, with a diameter between 1 nm (nanometer) and 10 nm. This is the very early stage of a fire. In the traditional technology, it is almost impossible for early detectors to detect a fire in this stage.

[0070] 2) The second stage is the depolymerization stage. In this stage, free radicals react with other substance molecules to generate new free radicals or combine with each other to form stable molecules, that is, smoke particles, with a diameter between 400 nm and 2000 nm. This is the initial stage of a fire accompanied by an increase in smoke concentration. In the traditional technology, smoke detectors are used to detect a fire. For example, point-type smoke detectors, infrared light beam smoke detectors, very early smoke detectors, etc.

[0071] 3) The third stage is the combustion stage. In this stage, a sufficient chain reaction is accompanied by luminescence, that is, a flame, releasing high temperature. This is the growth stage of a fire, generating a visible flame. In the traditional technology, flame detectors are used to detect a fire. For example, infrared / ultraviolet flame detectors, etc.

[0072] 4) The fourth stage is the high-temperature stage. In this stage, a sufficient chain reaction is accompanied by luminescence, that is, a flame, releasing high temperature. This is the fully developed stage of a fire, generating high temperature and flashover. In the traditional technology, temperature sensors are used to detect a fire. For example, point-type temperature detectors, etc.

[0073] As mentioned above, in the prevention and handling of distribution cabinet fires, traditional manual inspections and manual fire extinguishing methods have problems such as long inspection cycles, slow response, and low automation levels. It is difficult to detect and control the fire in a timely manner, increasing the risk of fire spread. Especially in environments such as high temperature, high humidity, high altitude, or confined spaces, the operability of manual fire extinguishing is limited. Therefore, how to improve the early warning and control capabilities of distribution cabinet fires has become an urgent problem to be solved.

[0074] Based on this, in an exemplary embodiment, as Figure 2As shown, a fire extinguishing device is provided, including a pyro-particle sensor 210, a controller 220, a heating component 230, and a storage component 240. Among them, a perfluoromethylcyclohexanone fire extinguishing agent is provided in the storage component 240. Among them:

[0075] The pyro-particle sensor 210 is used to detect the particle information of pyro-particles in the environment and transmit the particle information to the controller 220. Among them, the above particle information at least includes the particle diameter.

[0076] The pyro-particle sensor is also called a pyrolysis particle sensor, which is used to detect the particle information of pyro-particles generated during the pyrolysis process. The above particle information may include the particle diameter, the number of particles, the particle concentration, etc. It usually has the characteristics of high sensitivity, fast response, non-contact detection, and simultaneous detection of multiple parameters. Such as resistive pyro-particle sensors, capacitive pyro-particle sensors, optical pyro-particle sensors, semiconductor pyro-particle sensors, etc. Based on this, in this embodiment, the specific type of the above pyro-particle sensor 210 is not limited, and the above pyro-particle sensor 210 can detect the pyro-particles generated during the combustion process of substances to obtain particle information including at least the particle diameter.

[0077] In an optional embodiment, the above pyro-particle sensor 210 can detect the particle information of pyro-particles in the environment in real time, so as to realize real-time and continuous monitoring of environmental data, reduce manual dependence, and improve the timeliness of fire detection.

[0078] Furthermore, the above pyro-particle sensor 210 can perform data interaction with the above controller 220 through various methods such as Bluetooth, wired communication, WI-FI (Wireless Network Communication Technology), NFC (Near Field Communication), etc., so that the above pyro-particle sensor 210 can transmit the detected particle information to the above controller 220.

[0079] The controller 220 is used to judge whether there is a fire based on the above particle information, and in the case of a fire, control the heating component 230 to heat the storage component 240, so that the storage component is heated and melted to release the perfluoromethylcyclohexanone fire extinguishing agent in a gaseous form.

[0080] Generally, various controllers such as single-chip microcomputers, microcontroller units (MCUs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), and application specific integrated circuits (ASICs) are widely used in fields such as communication, electronics, and measurement and control due to their good data processing capabilities, strong computing functions, high integration levels, and strong logic functions.

[0081] Based on this, in this embodiment, the specific type of the above-mentioned controller 220 is not limited. After receiving the above-mentioned particle information, the controller 220 can determine whether there is a fire based on the above-mentioned particle information.

[0082] For example, if the particle information includes the particle diameter, the controller 220 can determine whether the above-mentioned particle diameter exceeds a preset diameter threshold, and if the judgment result is that it exceeds, it is determined that there is a fire.

[0083] For another example, if the particle information further includes the particle quantity, the controller 220 can simultaneously determine whether the above-mentioned particle diameter exceeds a preset diameter threshold and whether the particle quantity exceeds a preset quantity threshold, and if the judgment results are both yes, it is determined that there is a fire.

[0084] It should be emphasized that the above examples are only illustrative examples of the specific implementation manners of the controller 220 for determining whether there is a fire based on the above-mentioned particle information, rather than limitations. Any implementation manner that can enable the controller 220 to determine whether there is a fire based on particle information including at least the particle diameter belongs to the protection scope of this solution.

[0085] Based on this, the controller 220 can perform fire judgment based on the particle information, realize intelligent fire judgment, reduce false alarms and missed alarms, and improve the accuracy of fire recognition and the response speed to fires.

[0086] When it is determined that there is a fire, the controller 220 can control the heating component 230 to heat the storage component so that the storage component 240 is heated and melted and releases perfluoroketone fire extinguishing agent in a gaseous form.

[0087] In an alternative embodiment, when a fire is detected, the controller 220 can turn on the power supply of the heating component 230 to energize the heating component 230, causing the heating component 230 to rapidly increase in temperature.

[0088] In an alternative embodiment, the heating component 230 described above can be a heating wire.

[0089] In this embodiment, the heating component 230 can be disposed close to the storage component 240 so that after the heating component 230 increases in temperature, heat can be transferred to the storage component through thermal radiation, causing the storage component 240 to increase in temperature and realizing the heating of the storage component 240.

[0090] In an alternative embodiment, the heating component 230 described above is disposed at the bottom of the storage component 240.

[0091] In addition, the storage component 240 described above can exist in various forms such as tubular or boxed, and its material can be a plastic with a relatively low melting point and thermal conductivity.

[0092] Among them, perfluoromethylcyclohexanone fire extinguishing agent is a new type of clean, green and environmentally friendly fire extinguishing agent. It is a clear, colorless and odorless liquid at room temperature, is easy to vaporize, has excellent insulation performance, is non-conductive, leaves no residue after release, has no obvious chemical reaction with common rubber and plastic sealing materials, has no corrosion to common metal materials, and will not damage electronic components and circuits. Therefore, it is widely applicable to fire protection in various occasions such as electronic control centers, computer rooms, distribution rooms, distribution cabinets, wind turbine rooms, energy storage power stations, high-precision instruments, museums, data processing centers, ship control rooms, and the protection of new energy vehicle lithium batteries.

[0093] In an exemplary embodiment, the perfluoromethylcyclohexanone fire extinguishing agent is stored in a perfluoromethylcyclohexanone microcapsule in a liquid form, and the perfluoromethylcyclohexanone microcapsule is disposed in the storage component 240, and the melting temperature of the storage component 240 is higher than the melting temperature of the wall of the perfluoromethylcyclohexanone microcapsule.

[0094] In this embodiment, since the melting temperature of the storage component 240 is higher than the melting temperature of the wall of the perfluoromethylcyclohexanone microcapsule, after the storage component 240 is heated and melted, the temperature provided by the heating component 230 is already higher than the melting temperature of the wall of the perfluoromethylcyclohexanone microcapsule. Thus, the wall of the perfluoromethylcyclohexanone microcapsule melts, and the perfluoromethylcyclohexanone fire extinguishing agent stored in a liquid form is vaporized by heat and released into the environment in a gaseous form.

[0095] In this way, storing the perfluoromethylcyclohexanone fire extinguishing agent in a perfluoromethylcyclohexanone microcapsule in a liquid form can increase the dosage of the perfluoromethylcyclohexanone fire extinguishing agent stored in a single storage device, thereby improving the fire extinguishing effect.

[0096] Based on this, during the process of the heating component 230 heating the storage component 240, the perfluoromethyl hexanone fire extinguishing agent provided in the storage component 240 is heated simultaneously. Since the perfluoromethyl hexanone fire extinguishing agent is easy to vaporize, during the heating process of the above-mentioned heating component 230, the perfluoromethyl hexanone fire extinguishing agent provided in the storage component 240 is vaporized by heating. Thus, after the storage component 240 is heated and melted, the perfluoromethyl hexanone fire extinguishing agent, which has been converted into a gaseous form, is released, achieving the purpose of extinguishing the flame and reducing the temperature of the fire source, and realizing fire extinguishing.

[0097] In this way, when the controller 220 determines that there is a fire, the fire extinguishing program can be automatically triggered to achieve a timely response to the fire without manual intervention, shorten the fire extinguishing reaction time, and reduce the fire loss. Moreover, during the fire extinguishing process, the perfluoromethyl hexanone fire extinguishing agent is released rapidly, leaving no residue and having no conductivity during the fire extinguishing process, which can effectively protect the safety of various equipment in the event of a fire, improve the fire extinguishing effect, and achieve safe and efficient fire extinguishing. In addition, due to the excellent insulation performance of the perfluoromethyl hexanone fire extinguishing agent, it is non-conductive, leaves no residue after release, has no obvious chemical reaction with common rubber and plastic sealing materials, has no corrosion on common metal materials, and will not damage electronic components and circuits. Therefore, the above-mentioned fire extinguishing device can be applied to various scenarios such as substations, distribution cabinets, data centers, industrial factories, and underground distribution rooms, ensuring stable operation in extreme environments, and improving the adaptability and stability to complex environments.

[0098] In summary, compared with the limited operability of manual fire extinguishing and the problems of complex design, large construction workload, long time, need for regular maintenance, and the need to set in advance the capacity of the fire extinguishing agent, the number of nozzles and detectors, and the pipeline layout in the automatic fire extinguishing systems such as foam spraying and fire detection tubes in the traditional technology, and the fact that the construction process may affect the equipment layout and have an impact on the overall equipment or system, in this application, the above-mentioned fire extinguishing equipment, based on environmental data monitoring, realizes intelligent fire judgment and automatic fire extinguishing, has the advantages of intelligent monitoring, accurate identification, automatic response, and efficient fire extinguishing, significantly improves the early warning and control ability of distribution cabinet fires, significantly reduces the need for manual fire extinguishing, reduces the fire risk, and improves the safety and reliability of the distribution cabinet.

[0099] Considering the scenarios where the above-mentioned fire extinguishing equipment is used, in order to ensure the instant monitoring of the fire and the fire extinguishing effect, the number of heat release particle sensors 210, heating components 230, and storage components 240 in the above-mentioned fire extinguishing equipment can be adjusted according to the size of the above-mentioned scenarios, the distribution of flammable substances, etc. Moreover, in order to achieve accurate fire extinguishing and resource conservation on the premise of ensuring the fire extinguishing effect, some heating components can also be selectively heated according to the distribution of the fire to melt some of the storage components and release the perfluoromethyl hexanone fire extinguishing agent in a gaseous form.

[0100] Based on this, on the basis of the above embodiments, in an exemplary embodiment, the structure of the above fire extinguishing device is further refined. Optionally, the number of the heat release particle sensors 210, the heating components 230, and the storage components 240 of the above fire extinguishing device is multiple, and there is a corresponding relationship among the heat release particle sensors 210, the heating components 230, and the storage components 240.

[0101] In this embodiment, according to the usage scenario of the fire extinguishing device, multiple heat release particle sensors 210, heating components 230, and storage components 240 can be distributed and arranged. Among them, for the heat release particle sensor 210, it has a detection range and can detect particle information within its own detection range. When the controller 220 determines that there is a fire based on the particle information detected by a certain heat release particle sensor 210, it can indicate that there is a fire within the detection range of this heat release particle sensor 210. Thus, the heating components 230 located within and / or near the detection range of this heat release particle sensor 210 can be heated, so that these heating components 230 heat the storage components 240 within and / or near the detection range of this heat release particle sensor 210, causing these storage components 240 to melt and release the perfluorinated hexanone fire extinguishing agent in a gaseous form to extinguish the fire within the detection range of this heat release particle sensor 210.

[0102] Based on this, when multiple heat release particle sensors 210, heating components 230, and storage components 240 are distributed and arranged in the fire extinguishing device, a corresponding relationship among the heat release particle sensors 210, the heating components 230, and the storage components 240 is established.

[0103] In an alternative embodiment, for each heat release particle sensor 210, the heating components 230 located within the detection range of this heat release particle sensor 210 can be determined as the heating components 230 corresponding to this heat release particle sensor 210. Furthermore, the storage components 240 that can be heated by the above heating components 230 can be determined as the storage components 240 corresponding to this heat release particle sensor 210, thereby establishing a corresponding relationship among the heat release particle sensors 210, the heating components 230, and the storage components 240.

[0104] In an alternative embodiment, for each heat release particle sensor 210, the storage components 240 located within the detection range of this heat release particle sensor 210 can be determined as the storage components 240 corresponding to this heat release particle sensor 210. Furthermore, the heating components 230 used to heat the above storage components 240 can be determined as the heating components 230 corresponding to this heat release particle sensor 210, thereby establishing a corresponding relationship among the heat release particle sensors 210, the heating components 230, and the storage components 240.

[0105] Of course, the above embodiments are merely examples of the establishment method of the corresponding relationship between the pyroelectric particle sensor 210, the heating component 230, and the storage component 240, rather than limitations. Any implementation method that can establish the corresponding relationship between the pyroelectric particle sensor 210, the heating component 230, and the storage component 240 and achieve precise fire extinguishing in the area where a fire occurs belongs to the protection scope of this application.

[0106] Among them, in the fire extinguishing device, multiple pyroelectric particle sensors 210, heating components 230, and storage components 240 can be evenly distributed, or can be unevenly arranged according to the distribution of flammable materials, the distribution of important components, etc. in the used scenario. In this regard, this embodiment does not specifically limit the distribution of the multiple pyroelectric particle sensors 210, heating components 230, and storage components 240.

[0107] Correspondingly, in this embodiment, the above-mentioned controller 220 is further configured to determine the pyroelectric particle sensor 210 that transmits the particle information indicating the presence of a fire as the target pyroelectric particle sensor.

[0108] Among them, in this embodiment, for the controller 220 in the fire extinguishing device, it can receive the particle information transmitted by multiple pyroelectric particle sensors 210, and respectively judge whether there is a fire based on each particle information. When it is judged that there is a fire, the controller 220 can determine which pyroelectric particle sensor transmits the particle information indicating the presence of a fire, and thus determine the pyroelectric particle sensor 210 that transmits the particle information indicating the presence of a fire as the target pyroelectric particle sensor.

[0109] For example, there are three pyroelectric particle sensors 210-1, 210-2, and 210-3. The pyroelectric particle sensor 210-1 transmits particle information A to the controller 220, the pyroelectric particle sensor 210-2 transmits particle information B to the controller 220, and the pyroelectric particle sensor 210-3 transmits particle information C to the controller 220. The controller 220 judges that there is a fire based on the particle information B, then the controller 220 can determine the above-mentioned pyroelectric particle sensor 210-2 as the target pyroelectric particle sensor.

[0110] Furthermore, when the controller 220 executes the above-mentioned control to heat the storage component 240 by the heating component 230, it is used to: control the target heating component corresponding to the target pyroelectric particle sensor to heat the target storage component corresponding to the target pyroelectric particle sensor, so that the target storage component is heated and melted to release the perfluorinated hexanone fire extinguishing agent presented in a gaseous form.

[0111] In this embodiment, when the controller 220 determines the above-mentioned target pyroelectric particle sensor, it can determine that the target pyroelectric particle sensor monitors a fire, so there is a fire within its detection range. In order to achieve precise fire extinguishing for the above-mentioned fire and not waste the storage components and perfluoromethylcyclohexane fire extinguishing agent set in other areas without fire, it is possible to only melt the storage components in the area where the fire occurs and release the perfluoromethylcyclohexane fire extinguishing agent in gaseous form.

[0112] Based on this, the controller 220 can determine the target heating component corresponding to the target pyroelectric particle sensor according to the corresponding relationship between the pyroelectric particle sensor 210, the heating component 230, and the storage component 240, and thus control the target heating component corresponding to the target pyroelectric particle sensor. After the above-mentioned target heating component is heated, it can heat the target storage component corresponding to the target pyroelectric particle sensor, so that the above-mentioned target storage component is heated and melted and releases the perfluoromethylcyclohexane fire extinguishing agent in gaseous form.

[0113] In an optional embodiment, the controller 220 records the power supplies of the heating components 230. After determining the target heating component corresponding to the above-mentioned target pyroelectric particle sensor, the controller 220 can turn on the power supply of the above-mentioned target heating component to energize the target heating component.

[0114] In this embodiment, by establishing the corresponding relationship between the pyroelectric particle sensor 210, the heating component 230, and the storage component 240, it is possible to selectively heat some heating components according to the distribution of the fire in the case of determining that there is a fire, so as to melt some storage components and release the perfluoromethylcyclohexane fire extinguishing agent in gaseous form. Thus, it is possible to achieve precise fire extinguishing and resource conservation on the premise of ensuring the fire extinguishing effect.

[0115] On the basis of the above-mentioned embodiment, in an exemplary embodiment, the function of the above-mentioned controller 220 is further refined. Optionally, the above-mentioned controller 220 is further configured to send an update prompt of the target storage component to the server.

[0116] In this embodiment, when using the above-mentioned fire extinguishing equipment to extinguish a fire, some or all of the storage components 240 in the fire extinguishing equipment melt and release the perfluoromethylcyclohexane fire extinguishing agent set in themselves in gaseous form. That is, the storage components 240 in the above-mentioned fire extinguishing equipment and the perfluoromethylcyclohexane fire extinguishing agent set in the storage components 240 are disposable devices and cannot be reused. Therefore, after the above-mentioned target storage component is heated and melted and releases the perfluoromethylcyclohexane fire extinguishing agent in gaseous form to extinguish the fire, in order to ensure the fire extinguishing effect of the fire extinguishing equipment in subsequent use, it is necessary to use a new storage component provided with perfluoromethylcyclohexane fire extinguishing agent to replace the melted storage component.

[0117] Based on this, when the controller 220 controls the target heating component corresponding to the target pyroelectric particle sensor to heat the target storage component corresponding to the target pyroelectric particle sensor, so that the target storage component is heated and melted to release the perfluoroketone fire extinguishing agent presented in gaseous form, the controller 220 can send an update prompt of the above target storage component to the server in various ways such as sending a prompt email and sending a prompt message.

[0118] In an optional embodiment, the controller 220 records the corresponding relationship between the identities of the pyroelectric particle sensor, the heating component, and the storage component, and records the corresponding relationship between the pyroelectric particle sensor, the heating component, and the storage component. Thus, the controller 220 can send an update prompt carrying the component representation of the target storage component to the server.

[0119] In an optional embodiment, the server records the corresponding relationship between the identities of the pyroelectric particle sensor, the heating component, and the storage component, and records the corresponding relationship between the pyroelectric particle sensor, the heating component, and the storage component. Thus, the controller 220 can send an update prompt carrying the sensor identity of the target pyroelectric particle sensor and / or the component identity of the target heating component to the server, so that the server determines the target storage component that needs to be updated according to the received sensor identity of the target pyroelectric particle sensor and / or the component identity of the target heating component, and outputs an update prompt for reminding to update the above target storage component.

[0120] Among them, the server can output the above update prompt in various ways. For example, the server can output the text content of the above update prompt on the display interface, mark the target storage component by highlighting or other means in the structure diagram of the fire extinguishing equipment, and output voice prompt information through an audio broadcast device.

[0121] In this embodiment, the staff can be reminded to replace the melted target storage component as soon as possible to ensure the fire extinguishing effect of the fire extinguishing equipment during subsequent use.

[0122] Based on the above embodiments, in an exemplary embodiment, a method for the controller 220 to determine whether there is a fire based on particle information is provided. As Figure 3 shown, the method may include the following steps:

[0123] S301, obtain particle information.

[0124] Among them, the particle information at least includes the particle diameter.

[0125] S302, determine whether the particle diameter meets the preset diameter condition.

[0126] Among them, the preset diameter condition includes being greater than the diameter threshold, and / or the diameter growth rate being greater than the first growth rate threshold.

[0127] As described above Figure 1A As shown above, in the very early stage of a fire, there will be heat release particles generated by combustibles reaching the heat loss value in the environment, and the particle diameters of the above heat release particles have a certain length. In the initial stage of the fire after further development, the heat release particles will react with other substances or combine with each other to form heat release particles with a larger particle diameter. That is, when the particle diameter of the heat release particles in the environment increases significantly, it can be determined that there is a fire in the environment. At this time, the fire may only be in the very early stage or the initial stage.

[0128] Based on this, after receiving the particle information transmitted by the heat release particle sensor, the controller 220 can determine whether there is a fire by judging whether the particle diameter of the heat release particles detected by the heat release particle sensor meets the preset diameter condition.

[0129] Generally, the significant increase in the particle diameter of the heat release particles can be measured from two dimensions. One dimension is whether the particle diameter of the detected heat release particles is greater than the diameter threshold, and the other dimension is whether the diameter growth rate of the particle diameter of the detected heat release particles is greater than the first growth rate threshold. Among them, the diameter growth rate refers to the growth rate of the particle diameter of the heat release particles compared to the initial diameter per unit time.

[0130] In this way, the above preset diameter condition may include: being greater than the diameter threshold, and / or, the diameter growth rate being greater than the first growth rate threshold. Specifically:

[0131] In an optional embodiment, the above preset diameter condition includes being greater than the diameter threshold. That is, when the controller 220 determines that the particle diameter of the heat release particles detected by the heat release particle sensor is greater than the diameter threshold, the controller 220 determines that the particle diameter meets the preset diameter condition.

[0132] In an optional embodiment, the above preset diameter condition includes the diameter growth rate being greater than the first growth rate threshold. That is, when the controller 220 determines that the diameter growth rate of the particle diameter of the heat release particles detected by the heat release particle sensor is greater than the first growth rate threshold, the controller 220 determines that the particle diameter meets the preset diameter condition.

[0133] In an optional embodiment, the above preset diameter condition includes being greater than the diameter threshold and the diameter growth rate being greater than the first growth rate threshold. That is, when the controller 220 determines that the particle diameter of the heat release particles detected by the heat release particle sensor is greater than the diameter threshold and the diameter growth rate is greater than the first growth rate threshold, the controller 220 determines that the particle diameter meets the preset diameter condition.

[0134] S303. When the particle diameter meets the preset diameter condition, it is determined that there is a fire.

[0135] As described above, when the controller 220 determines that the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor meets the preset diameter condition, the controller 220 may determine that a fire exists.

[0136] In this embodiment, by determining whether the particle diameter of the pyroelectric particles meets the preset diameter condition to determine whether a fire exists, since the particle diameter is not affected by whether the space is open or the size of the space, thus, it can be applicable to non-closed space scenarios and larger space scenarios as well as closed scenarios and smaller space scenarios, which can improve the applicable scenarios of the fire extinguishing equipment and improve the accuracy of fire monitoring.

[0137] Based on the above embodiments, in an exemplary embodiment, a method for the controller 220 to determine whether a fire exists based on particle information is provided. Among them, the above particle information further includes particle concentration, as Figure 4 shown, it may include the following steps:

[0138] S401, Obtain particle information.

[0139] Among them, the particle information includes particle diameter and particle concentration.

[0140] S402, Determine whether the particle diameter meets the preset diameter condition, and determine whether the particle concentration is greater than the first concentration threshold.

[0141] Among them, the preset diameter condition includes being greater than the diameter threshold, and / or, the diameter growth rate is greater than the first growth rate threshold.

[0142] As described above Figure 1A shown, in the very early stage and the initial stage of a fire, although there is no visible flame in the environment and the temperature has not risen significantly, a large amount of pyroelectric particles have been released by the combustibles, and as the fire continues to develop, the particle diameter and particle concentration of the pyroelectric particles released by the combustibles can increase significantly. That is, when the particle diameter of the pyroelectric particles in the environment increases significantly, and / or, the particle concentration of the pyroelectric particles in the environment increases significantly, it can be determined that there is a fire in the environment. At this time, the fire may only be in the very early stage or the initial stage.

[0143] Based on this, after receiving the particle information transmitted by the pyroelectric particle sensor, the controller 220 can determine whether a fire exists by determining whether the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor 210 meets the preset diameter condition and whether the particle concentration is greater than the first concentration threshold.

[0144] Similar to the above method of measuring whether the particle diameter of the thermally released particles has increased significantly, the particle concentration of the thermally released particles can also be measured from two dimensions. One dimension is whether the particle concentration of the detected thermally released particles is greater than the first concentration threshold, and the other dimension is whether the concentration growth rate of the particle concentration of the detected thermally released particles is greater than the second growth rate threshold. Here, the concentration growth rate of the particle concentration refers to the growth rate of the particle concentration of the thermally released particles compared to the initial concentration per unit time.

[0145] In this way, the above first concentration condition may include being greater than the first concentration threshold, and / or the concentration growth rate being greater than the second growth rate threshold. Specifically:

[0146] In an optional embodiment, the above first concentration condition includes being greater than the first concentration threshold. That is, when the controller 220 determines that the particle concentration of the thermally released particles detected by the thermally released particle sensor is greater than the first concentration threshold, the controller 220 determines that the particle concentration meets the first concentration condition.

[0147] In an optional embodiment, the above first concentration condition includes the concentration growth rate being greater than the second growth rate threshold. That is, when the controller 220 determines that the concentration growth rate of the particle concentration of the thermally released particles detected by the thermally released particle sensor is greater than the second growth rate threshold, the controller 220 determines that the particle concentration meets the first concentration condition.

[0148] In an optional embodiment, the above first concentration condition includes being greater than the first concentration threshold and the concentration growth rate being greater than the second growth rate threshold. That is, when the controller 220 determines that the particle concentration of the thermally released particles detected by the thermally released particle sensor is greater than the first concentration threshold and the concentration growth rate is greater than the second growth rate threshold, the controller 220 determines that the particle concentration meets the first concentration condition.

[0149] S403, when the particle diameter meets the preset diameter condition, and / or the particle concentration meets the first concentration condition, it is determined that there is a fire.

[0150] As described above, when the controller 220 determines that the particle diameter of the thermally released particles detected by the thermally released particle sensor meets the preset diameter condition, and / or the particle concentration meets the first concentration condition, the controller 220 can determine that there is a fire.

[0151] In an optional embodiment, when the controller 220 determines that the particle diameter of the thermally released particles detected by the thermally released particle sensor meets the preset diameter condition, regardless of whether the particle concentration meets the first concentration condition, the controller 220 can determine that there is a fire.

[0152] In an alternative embodiment, when the controller 220 determines that the particle concentration of the pyroelectric particles detected by the pyroelectric particle sensor satisfies the first concentration condition, regardless of whether the particle diameter satisfies the preset diameter condition, the controller 220 can determine that a fire exists.

[0153] In an alternative embodiment, when the controller 220 determines that the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor satisfies the preset diameter condition and the particle concentration satisfies the first concentration condition, the controller 220 can determine that a fire exists.

[0154] In this embodiment, the controller 220 determines whether a fire exists based on a comprehensive analysis of multiple parameters, which can further reduce false alarms and missed alarms, thereby further improving the accuracy of fire identification and further enhancing the early warning ability of fires.

[0155] Based on the above embodiments, in an exemplary embodiment, the structure of the fire extinguishing device and the method by which the controller 220 determines whether a fire exists based on particle information are further refined. Optionally, as Figure 5A shown, the fire extinguishing device may further include a gas sensor 250.

[0156] The gas sensor 250 is configured to detect the gas components in the environment and transmit the above gas components to the controller 220.

[0157] It can be understood that during the development of a fire, as the pyroelectric particles released by the thermal decomposition of combustibles increase and the combustibles burn, compared with the environment before the fire occurs, other components in the air will change, increasing combustible gases such as sulfur dioxide, and the concentration of the above combustible gases will also gradually increase. Therefore, a gas sensor can be added to the fire extinguishing device to assist the controller 220 in fire situation judgment by detecting changes in the gas components in the air, improving the accuracy and timeliness of fire situation judgment.

[0158] Among them, the above gas sensor 250 can detect the gas components in the environment and transmit the above gas components to the controller 220, and the gas components detected by the above gas sensor 250 can include the type of gas components, the concentration of the extracted components, etc. In this embodiment, the specific type of the above gas sensor 250 is not limited, such as a single gas sensor for detecting a specific gas, a composite gas sensor commonly used in complex environments that can detect multiple gases simultaneously, etc.

[0159] In the above Figure 5ABased on the embodiments shown, in an alternative embodiment, the manner in which the controller 220 determines whether there is a fire based on particle information may further include: in the case where it is determined based on the particle information that there is no fire, determining whether the gas concentration of a specified gas in the gas composition satisfies a second concentration condition, and in the case where the gas concentration satisfies the second concentration condition, determining that there is a fire.

[0160] Wherein, the second concentration condition includes: being greater than a second concentration threshold, and / or, the concentration growth rate being greater than a third growth rate threshold.

[0161] In the case where it is determined based on the particle information detected by the pyroelectric particle sensor 210 that there is no fire, in order to improve the accuracy of the finally obtained fire judgment result and ensure that a fire can be detected in a timely manner, the controller 220 may further determine whether there is a fire based on the gas composition.

[0162] As mentioned above, during the development of a fire, combustible gases such as sulfur dioxide will be added to the air, and the concentration of the above-mentioned combustible gases will also gradually increase. Therefore, according to the usage scenario of the fire extinguishing equipment, various gases that can be generated during combustion can be used to determine a specified gas, such as a combustible gas like sulfur dioxide. Then, in the case where the gas concentration of the above-mentioned specified gas in the environment increases significantly, it can be determined that there is a fire in the environment.

[0163] Similar to the above-mentioned method of measuring whether the particle concentration of pyroelectric particles increases significantly, it is also possible to measure whether the gas concentration of the specified gas increases significantly from two dimensions. One dimension is whether the gas concentration of the specified gas in the detected gas composition is greater than the second concentration threshold, and the other dimension is whether the concentration growth rate of the gas concentration of the specified gas in the detected gas composition is greater than the third growth rate threshold. Among them, the concentration growth rate of the gas concentration refers to the growth rate of the gas concentration of the specified gas in the gas composition compared to the initial concentration per unit time.

[0164] In this way, the above-mentioned second concentration condition may include being greater than the second concentration threshold, and / or, the concentration growth rate being greater than the third growth rate threshold. Specifically:

[0165] In an alternative embodiment, the above-mentioned second concentration condition includes being greater than the second concentration threshold. That is, in the case where the controller 220 determines that the gas concentration of the specified gas in the gas composition is greater than the second concentration threshold, the controller 220 determines that the gas concentration satisfies the second concentration condition.

[0166] In an alternative embodiment, the above-mentioned second concentration condition includes the concentration growth rate being greater than the third growth rate threshold. That is, in the case where the controller 220 determines that the concentration growth rate of the gas concentration of the specified gas in the gas composition is greater than the third growth rate threshold, the controller 220 determines that the gas concentration satisfies the second concentration condition.

[0167] In an alternative embodiment, the first concentration condition described above includes being greater than a second concentration threshold and a concentration growth rate being greater than a third growth rate threshold. That is, when the controller 220 determines that the gas concentration of the specified gas in the gas composition is greater than the second concentration threshold and the concentration growth rate is greater than the third growth rate threshold, the controller 220 determines that the gas concentration satisfies the second concentration condition.

[0168] In this way, when the controller 220 determines that there is no fire based on the particle information detected by the pyroelectric particle sensor 210 described above, the controller 220 can determine whether the gas concentration of the specified gas in the gas composition detected by the gas sensor 250 satisfies the second concentration condition. And when the controller 220 determines that the above gas concentration satisfies the second concentration condition, the controller 220 can determine that there is a fire.

[0169] In this embodiment, when it is determined that there is no fire based on the above particle information, the controller 220 can further determine whether there is a fire based on the gas composition. Thus, by comprehensively analyzing multiple parameters to determine whether there is a fire, false alarms and missed alarms can be further reduced, thereby further improving the accuracy of fire recognition and further enhancing the early warning ability of fires.

[0170] In the above Figure 5A On the basis of the embodiment shown, in an exemplary embodiment, a method for the controller 220 to determine whether there is a fire based on particle information is provided. As Figure 5B shown, it may include the following steps:

[0171] S501, Obtain particle information and gas composition.

[0172] Among them, the particle information includes at least the particle diameter, and the gas composition includes the gas concentration of the specified gas.

[0173] S502, Determine whether the particle diameter satisfies a preset diameter condition and determine whether the gas concentration satisfies a preset concentration condition.

[0174] As described above, after receiving the particle information transmitted by the pyroelectric particle sensor and the gas composition transmitted by the gas sensor, the controller 220 can determine whether there is a fire by determining whether the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor 210 satisfies the preset diameter condition and whether the gas concentration of the specified gas in the gas composition detected by the gas sensor 250 satisfies the second concentration condition.

[0175] S503, When the particle diameter satisfies the preset diameter condition and the gas concentration satisfies the preset concentration condition, determine that there is a fire.

[0176] When the controller 220 determines that the above particle diameter meets the diameter condition and the above gas concentration meets the second concentration condition, the controller 220 may determine that there is a fire. Among them, as described above, the preset diameter condition includes being greater than the diameter threshold, and / or the diameter growth rate being greater than the first growth rate threshold, and the second concentration condition includes being greater than the second concentration threshold, and / or the concentration growth rate being greater than the third growth rate threshold.

[0177] In this embodiment, the controller 220 may comprehensively determine whether there is a fire based on the above particle information and gas components. Thus, based on the comprehensive analysis of multiple parameters, false alarms and missed alarms can be further reduced, thereby further improving the accuracy of fire recognition and further enhancing the early warning ability of fires.

[0178] Based on the above embodiments, in an exemplary embodiment, the structure of the fire extinguishing device and the manner in which the controller 220 determines whether there is a fire based on particle information are further refined. Optionally, as Figure 6A shown, the fire extinguishing device may further include a temperature sensor 260.

[0179] The temperature sensor 260 is used to detect the ambient temperature of the environment and transmit the ambient temperature to the controller 220.

[0180] It can be understood that, as shown above Figure 1A shown, as the fire gradually develops, the burning of combustibles will release high temperatures, thereby greatly increasing the ambient temperature and causing the ambient temperature to rise abnormally. Therefore, a temperature sensor can be added to the fire extinguishing device to assist the controller 220 in fire judgment by detecting the ambient temperature, improving the accuracy and timeliness of fire judgment.

[0181] In this embodiment, the specific type of the above temperature sensor 260 is not limited, such as a thermocouple temperature sensor, a thermal resistance temperature sensor, a thermistor temperature sensor, an infrared temperature sensor, etc.

[0182] In the above Figure 6A Based on the embodiment shown above, in an alternative embodiment, the manner in which the controller 220 determines whether there is a fire based on particle information may further include: when it is determined that there is no fire based on particle information, determining whether the ambient temperature meets a preset temperature condition, and when the ambient temperature meets the preset temperature condition, determining that there is a fire.

[0183] Among them, the preset temperature condition includes being greater than the temperature threshold, and / or the temperature growth rate being greater than the fourth growth rate threshold.

[0184] When it is determined that there is no fire based on the particle information detected by the pyroelectric particle sensor 210 described above, in order to improve the accuracy of the final fire judgment result and ensure that a fire can be detected in a timely manner, the controller 220 can further determine whether there is a fire based on the ambient temperature.

[0185] As described above, as a fire gradually develops, the combustion of combustibles releases high temperatures, thus greatly increasing the ambient temperature and causing the ambient temperature to rise abnormally. Therefore, when the ambient temperature increases significantly, it can be determined that there is a fire in the environment.

[0186] Similar to the above method of measuring whether the particle concentration of pyroelectric particles increases significantly, the increase in ambient temperature can also be measured from two dimensions. One dimension is whether the detected ambient temperature is greater than the temperature threshold, and the other dimension is whether the temperature growth rate of the detected ambient temperature is greater than the fourth growth rate threshold. The temperature growth rate of the ambient temperature refers to the growth rate of the ambient temperature compared to the initial temperature per unit time.

[0187] In an optional embodiment, the above preset temperature condition includes being greater than the temperature threshold. That is, when the controller 220 determines that the ambient temperature is greater than the temperature threshold, the controller 220 determines that the ambient temperature meets the preset temperature condition.

[0188] In an optional embodiment, the above preset temperature condition includes that the temperature growth rate is greater than the fourth growth rate threshold. That is, when the controller 220 determines that the temperature growth rate of the ambient temperature is greater than the fourth growth rate threshold, the controller 220 determines that the ambient temperature meets the preset temperature condition.

[0189] In an optional embodiment, the above preset temperature condition includes being greater than the temperature threshold and the temperature growth rate being greater than the fourth growth rate threshold. That is, when the controller 220 determines that the ambient temperature is greater than the temperature threshold and the temperature growth rate is greater than the fourth growth rate threshold, the controller 220 determines that the ambient temperature meets the preset temperature condition.

[0190] In this way, when the controller 220 determines that there is no fire based on the particle information detected by the pyroelectric particle sensor 210 described above, the controller 220 can determine whether the ambient temperature detected by the temperature sensor 260 meets the preset temperature condition, and when the controller 220 determines that the above ambient temperature meets the preset temperature condition, the controller 220 can determine that there is a fire.

[0191] In this embodiment, when it is determined based on the above particle information that there is no fire, the controller 220 can further determine whether there is a fire based on the ambient temperature. Thus, based on comprehensive multi-parameter analysis, it is possible to further reduce false alarms and missed alarms, thereby further improving the accuracy of fire recognition and further enhancing the early warning ability for fires.

[0192] Based on the above Figure 6A On the basis of the embodiment shown above, in an exemplary embodiment, a method for the controller 220 to determine whether there is a fire based on particle information is provided. As Figure 6B shown, it may include the following steps:

[0193] S601, Obtain particle information and ambient temperature.

[0194] Among them, the particle information includes at least the particle diameter.

[0195] S602, Determine whether the particle diameter meets the preset diameter condition, and determine whether the ambient temperature meets the preset temperature condition.

[0196] As described above, after receiving the particle information transmitted by the pyroelectric particle sensor and the ambient temperature transmitted by the temperature sensor, the controller 220 can determine whether there is a fire by determining whether the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor 210 meets the preset diameter condition, and whether the ambient temperature detected by the temperature sensor 260 meets the preset temperature condition.

[0197] S603, When the particle diameter meets the preset diameter condition and the ambient temperature meets the preset temperature condition, determine that there is a fire.

[0198] When the controller 220 determines that the above particle diameter meets the diameter condition and the above ambient temperature meets the preset temperature condition, the controller 220 can determine that there is a fire. Among them, as described above, the preset diameter condition includes being greater than the diameter threshold, and / or the diameter growth rate being greater than the first growth rate threshold, and the preset temperature condition includes being greater than the temperature threshold, and / or the temperature growth rate being greater than the fourth growth rate threshold.

[0199] In this embodiment, the controller 220 can comprehensively determine whether there is a fire based on the above particle information and ambient temperature. Thus, based on comprehensive multi-parameter analysis, it is possible to further reduce false alarms and missed alarms, thereby further improving the accuracy of fire recognition and further enhancing the early warning ability for fires.

[0200] On the basis of the above embodiments, in an exemplary embodiment, the structure of the fire extinguishing equipment and the method for the controller 220 to determine whether there is a fire based on particle information are further refined. Optionally, asFigure 7A As shown, the fire extinguishing equipment may further include a gas sensor 250 and a temperature sensor 260.

[0201] The gas sensor 250 is used to detect the gas components in the environment and transmit the above gas components to the controller 220.

[0202] The temperature sensor 260 is used to detect the ambient temperature of the environment and transmit the ambient temperature to the controller 220.

[0203] Wherein, the above Figure 7A The gas sensor 250 therein is the same as the gas sensor 250 above, and the temperature sensor 260 therein is the same as the temperature sensor 260 above, which will not be elaborated here. Figure 5A in the above Figure 7A in the above Figure 6A in the above

[0204] Based on the above Figure 7A On the basis of the embodiment shown above, in an alternative embodiment, the manner in which the controller 220 determines whether there is a fire based on the particle information may further include: when it is determined based on the particle information that there is no fire, determining whether the gas concentration of a specified gas in the gas components meets a second concentration condition, and determining whether the ambient temperature meets a preset temperature condition; when the gas concentration meets the second concentration condition, and / or, the ambient temperature meets the preset temperature condition, determining that there is a fire.

[0205] Wherein, the second concentration condition includes being greater than a second concentration threshold, and / or, the concentration growth rate being greater than a third growth rate threshold; the preset temperature condition includes being greater than a temperature threshold, and / or, the temperature growth rate being greater than a fourth growth rate threshold.

[0206] As described above, when the gas concentration of the specified gas in the gas components of the environment increases significantly, it can be determined that there is a fire in the environment, and when the ambient temperature increases significantly, it can be determined that there is a fire in the environment.

[0207] Based on this, when the controller 220 determines based on the particle information detected by the above pyroelectric particle sensor 210 that there is no fire, in order to improve the accuracy of the finally obtained fire judgment result and ensure that a fire can be monitored in a timely manner, the controller 220 may determine whether there is a fire based on the gas components and the ambient temperature.

[0208] When the controller 220 determines that there is no fire based on the above particle information, the controller 220 may determine whether the gas concentration of the specified gas in the gas components detected by the gas sensor 250 meets the second concentration condition, and determine whether the ambient temperature detected by the temperature sensor 260 meets the preset temperature condition. In this way, when the controller 220 determines that the above gas concentration meets the second concentration condition, and / or the above ambient temperature meets the preset temperature condition, the controller 220 may determine that there is a fire.

[0209] In an optional embodiment, when the controller 220 determines that there is no fire based on the above particle information, if the controller 220 determines that the above gas concentration meets the second concentration condition, then regardless of whether the above ambient temperature meets the preset temperature condition, the controller 220 may determine that there is a fire.

[0210] In an optional embodiment, when the controller 220 determines that there is no fire based on the above particle information, if the controller 220 determines that the above ambient temperature meets the preset temperature condition, then regardless of whether the above gas concentration meets the second concentration condition, the controller 220 may determine that there is a fire.

Thus, based on the comprehensive analysis of multiple parameters, it is possible to determine whether there is a fire, further reduce false alarms and missed alarms, and thus further improve the accuracy of fire recognition and further improve the early warning ability of fires.

[0217] As described above, after receiving the particle information transmitted by the pyroelectric particle sensor, the gas composition transmitted by the gas sensor, and the ambient temperature transmitted by the temperature sensor, the controller 220 can determine whether there is a fire by judging whether the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor 210 meets the preset diameter condition, whether the gas concentration of the specified gas in the gas composition detected by the gas sensor 250 meets the second concentration condition, and whether the ambient temperature detected by the temperature sensor 260 meets the preset temperature condition.

[0224] In this embodiment, when it is determined based on the above particle information that there is no fire, the controller 220 can further determine whether there is a fire based on the gas concentration and the ambient temperature. Thus, based on a comprehensive multi-parameter analysis, it can be determined whether there is a fire, which can further reduce false alarms and missed alarms, and thus further improve the accuracy of fire identification and further enhance the early warning ability of fires.

[0225] Based on the above Figure 7A On the basis of the embodiment shown above, in an alternative embodiment, the manner in which the controller 220 determines whether there is a fire based on particle information may be to determine whether the particle diameter meets a preset diameter condition, whether the gas concentration meets a second concentration condition, and whether the ambient temperature meets a preset temperature condition; when it is determined that at least one of the particle diameter meets the preset diameter condition, the gas concentration meets the second concentration condition, and the ambient temperature meets the preset temperature condition, it is determined that there is a fire.

[0226] As described above, the controller 220 can determine whether there is a fire by determining whether the particle diameter of the pyroelectric particles detected by the pyroelectric particle sensor 210 meets the preset diameter condition, whether the gas concentration of the specified gas in the gas components detected by the gas sensor 250 meets the second concentration condition, and whether the ambient temperature detected by the temperature sensor 260 meets the preset temperature condition.

[0227] In an alternative embodiment, when the controller 220 determines that the particle diameter meets the preset diameter condition, regardless of whether the gas concentration meets the second concentration condition and whether the ambient temperature meets the preset temperature condition, the controller 220 can determine that there is a fire.
