Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology for cabinets, and more particularly to an intelligent fire extinguishing patch and fire extinguishing method for cabinet-type equipment. Background Technology

[0002] Electrical fires generally refer to fires caused by the release of heat energy due to malfunctions in electrical circuits, electrical equipment, appliances, and power supply and distribution equipment. These malfunctions include high temperatures, electric arcs, and electric sparks, as well as non-malfunction releases of heat energy, such as the hot surface of electric heating appliances, which ignite the appliance itself or other combustibles under conditions conducive to combustion. Fires caused by lightning and static electricity are also included.

[0003] The current situation regarding fire safety in the power sector is severe, with most fires caused by electrical issues. The main reasons for this are that faults in electrical lines, equipment, appliances, and power distribution equipment can generate energy, high temperatures, electric arcs, and electric sparks, which can then ignite flammable materials and cause large-scale fires. Furthermore, transmission lines, equipment, and various cabinet-type and box-type appliances can age faster under prolonged continuous operation, leading to fires, with the situation being even more pronounced for equipment exposed outdoors.

[0004] On the other hand, electrical fires have certain unique characteristics. They are invisible and intangible before they occur. When an electrical fire shows signs of starting, it should be detected and dealt with promptly. However, existing fire protection systems often only provide preventative measures and cannot detect fires in their early stages. Once an electrical fire occurs and has reached a certain size, it is often not discovered until the fire has already been extinguished by the time fire extinguishing equipment is used. Therefore, existing methods that rely on manual monitoring or traditional fire extinguishing equipment cannot meet the actual needs of handling electrical fires and thus cannot improve the speed of fire response.

[0005] Therefore, there is an urgent need to design a new intelligent fire extinguishing sticker and fire extinguishing method for cabinet-type equipment to improve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent fire extinguishing sticker and fire extinguishing method for cabinet-type equipment, so as to realize the automatic handling of electrical fires, respond in a timely manner when disasters occur, prevent the disaster from spreading, and make up for the shortcomings of traditional fire extinguishing equipment.

[0029] When the real-time temperature is lower than the first preset temperature, the analysis module determines that it will not evaluate the early warning score inside the cabinet equipment.

[0030] When the real-time temperature is greater than or equal to the first preset temperature and the real-time temperature is less than the second preset temperature, the analysis module determines to evaluate the warning score inside the cabinet equipment and determines the warning score to be L1.

[0031] When the real-time temperature is greater than the second preset temperature, the analysis module determines to evaluate the warning score inside the cabinet equipment and determines the warning score to be L2.

[0032] Wherein, the first preset temperature is less than the second preset temperature, and L1 < L2.

[0033] As a preferred solution for intelligent fire extinguishing patches used in cabinet-type equipment, when the analysis module determines that the early warning score inside the cabinet-type equipment is Li, i = 1, 2, it includes:

[0035] When the real-time concentration is less than the first preset concentration, the analysis module determines not to adjust the warning score Li;

[0036] When the real-time concentration is greater than or equal to the first preset concentration and the real-time concentration is less than the second preset concentration, the analysis module determines an adjustment coefficient based on the concentration difference between the real-time concentration and the first preset concentration, and adjusts the warning score Li according to the adjustment coefficient.

[0037] When the real-time concentration is greater than or equal to the second preset concentration, the analysis module determines the adjustment coefficient as Mmax and adjusts the warning score Li according to the adjustment coefficient Mmax.

[0038] As a preferred solution for intelligent fire extinguishing patches used in cabinet-type equipment, when the analysis module determines the adjustment coefficient based on the concentration difference between the real-time concentration and the first preset concentration, it includes:

[0039] The analysis module is further configured to determine the adjustment coefficient based on the relationship between the concentration difference and a first preset concentration difference and a second preset concentration difference pre-configured by the analysis module.

[0040] When the concentration difference is less than the first preset concentration difference, the analysis module determines the adjustment coefficient to be M1;

[0041] When the concentration difference is greater than or equal to the first preset concentration difference and less than the second preset concentration difference, the analysis module determines the adjustment coefficient to be M2.

[0043] Wherein, the first preset concentration difference is less than the second preset concentration difference, and M1 < M2 < M3 < Mamx.

[0044] As a preferred embodiment of intelligent fire extinguishing patches for cabinet-type equipment, the central control module is configured to determine the warning level based on the relationship between the warning score inside the cabinet-type equipment and a pre-configured first preset warning score and a second preset warning score, and to determine the injection and release method of the fire extinguishing gas based on the warning level, including:

[0045] The central control module is also used to determine the warning level based on the relationship between the warning score and the first preset warning score and the second preset warning score, and to determine the exhaust fan flow rate and the opening degree of the closing valve based on the warning level:

[0046] When the warning score is less than the first preset warning score, the central control module determines that the warning level is low, and determines that the exhaust fan flow rate is Q1 and the opening degree of the closed valve is A1.

[0047] When the warning score is greater than or equal to the first preset warning score and less than the second preset warning score, the central control module determines the warning level to be medium level, and determines the exhaust fan flow rate to be Q2 and the opening degree of the closed valve to be A2.

[0048] When the warning score is greater than or equal to the second preset warning score, the central control module determines that the warning level is high level, and determines that the exhaust fan flow rate is Q3 and the opening degree of the closed valve is A3;

[0049] Wherein, the first preset warning score is less than the second preset warning score, and Q1 < Q2 < Q3 < 100%; A1 < A2 < A3 < 100%.

[0050] The fire extinguishing method for cabinet-type equipment, based on the smart fire extinguishing stickers for cabinet-type equipment mentioned above, includes the following steps:

[0051] To obtain the real-time temperature inside the cabinet-type equipment and the concentration of specific gas molecules inside the cabinet-type equipment;

[0052] Early warning features are established based on the historical operating data of the cabinet equipment and the fault data in the historical operating data. The early warning score inside the cabinet equipment is determined based on the relationship between the real-time temperature and specific gas molecule concentration of the cabinet equipment and the early warning features.

[0053] The warning level is determined based on the relationship between the warning score inside the cabinet equipment and the pre-configured first and second preset warning scores, and the method of spraying and releasing the fire extinguishing gas is determined based on the warning level.

[0054] The beneficial effects of this invention are:

[0055] The intelligent fire extinguishing patch for cabinet-type equipment proposed in this invention can continuously monitor the interior of the equipment through temperature detection and odor detection modules. This not only detects internal temperature changes but also identifies potential fire hazards by detecting the concentration of specific gas molecules, such as harmful gases released in the early stages of combustion. This multi-sensor collaborative working mode significantly improves the sensitivity and accuracy of fire monitoring, reducing the probability of fires. Secondly, the analysis module establishes early warning characteristics for the equipment by utilizing historical operating and fault data. This data-driven model enables the fire extinguishing patch to not only identify early signs of fire but also to provide an early warning score based on real-time data, reflecting the current fire risk level faced by the equipment. This early warning mechanism effectively avoids the limitations of traditional equipment that relies excessively on temperature thresholds, ensuring earlier fire warnings. Furthermore, through the central control module, the appropriate fire extinguishing gas release method is automatically selected according to different warning levels. This graded response mechanism can accurately handle fire hazards of varying severity. Finally, the design of the adsorption component allows the intelligent fire extinguishing patch to be easily installed on the surface of the cabinet-type equipment, while the raised plate structure ensures its firmness. This simple and reliable mounting method not only simplifies the installation process but also reduces the maintenance burden on operation and maintenance personnel, thereby improving the practicality of the equipment.

[0056] The fire extinguishing method for cabinet-type equipment proposed in this invention has the same beneficial effects as the aforementioned intelligent fire extinguishing patch for cabinet-type equipment, and will not be described further here. Attached Figure Description

[0065] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0066] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0068] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0069] like Figures 1-3 As shown, this embodiment provides a smart fire extinguishing sticker for cabinet-type equipment. The smart fire extinguishing sticker for cabinet-type equipment includes a gas storage tank 1, a gas release component 2, an adsorption component, a temperature detection module, an odor detection module, an analysis module, and a central control module.

[0070] Specifically, such as Figure 1 As shown, the gas storage tank 1 has a rectangular and hollow structure with a storage cavity inside for storing fire extinguishing gas. This dedicated storage cavity ensures the rapid release of the fire extinguishing gas in the event of a fire. A gas release assembly 2 is located on one side of the gas storage tank 1 and connected to it. It sprays and releases the fire extinguishing gas from the storage cavity, evenly distributing it near the fire source to create an effective fire extinguishing environment. This rapid response mechanism significantly improves fire extinguishing efficiency, ensuring effective control of the fire in its early stages and preventing further deterioration. An adsorption assembly is located on the other side of the gas storage tank 1, connecting it to the target location. The adsorption assembly and gas release assembly 2 are positioned on opposite sides of the gas storage tank 1, allowing the tank to be attached to the target location for easy installation and removal.

[0071] Secondly, real-time monitoring of temperature and gas concentration is a crucial feature of smart fire extinguishing patches. Therefore, a temperature detection module (not shown in the figure) is installed on the outside of the gas storage tank 1 to detect the real-time temperature inside the cabinet-type equipment. An odor detection module (not shown in the figure) is installed on top of the temperature detection module to detect the concentration of specific gas molecules inside the cabinet-type equipment. By continuously monitoring the temperature inside the cabinet-type equipment, the temperature detection module can quickly identify abnormal temperature increases, a significant precursor to fire. Simultaneously, the odor detection module allows the system to detect changes in the concentration of specific gas molecules, such as harmful gases that may be caused by equipment malfunction or fire. This dual monitoring mechanism ensures that the equipment can promptly identify potential fire risks and provide first-hand data for subsequent analysis.

[0072] Furthermore, the analysis module (not shown in the figure) is electrically connected to the temperature detection module and the odor detection module, respectively. The analysis module is used to establish early warning features based on the historical operating data of the cabinet equipment and the fault data within that historical data. In addition, the analysis module is also used to determine the early warning score inside the cabinet equipment based on the relationship between the real-time temperature and specific gas molecule concentrations and the early warning features. It establishes early warning features through historical operating data and fault data, and calculates the early warning score by comparing real-time data with these features. The intelligent functions of the analysis module provide a higher level of safety for the system. This module can not only integrate historical operating data and fault data to establish early warning features, but also analyze the relationship between current temperature and gas concentration data and these features in real time, calculating the real-time early warning score. This data-driven analysis method can improve the system's sensitivity to fire risks, ensure rapid response, and provide accurate decision-making basis for the central control module.

[0073] Finally, the central control module (not shown in the figure) is electrically connected to the analysis module and the gas release component 2. The central control module is configured to determine the warning level based on the relationship between the warning score inside the cabinet equipment and the pre-configured first and second preset warning scores, and to determine the injection and release method of the extinguishing gas according to the warning level. By comparing the warning score with the preset first and second preset warning scores, the central control module can accurately determine the current fire risk level and decide on the injection and release method of the extinguishing gas. According to different warning levels, the system can flexibly adjust the gas release method and intensity to adapt to different fire scenarios. This intelligent response capability not only improves the effectiveness of fire extinguishing but also reduces the waste of fire extinguishing resources and improves the overall fire extinguishing efficiency.

[0074] like Figure 1 and Figure 2As shown, the gas release assembly 2 in this embodiment includes a movable plate 21 and a jetting unit 22. A mounting block 211 is provided on one end face of the movable plate 21 and one side of the gas storage tank 1, while a mounting groove 11 is provided on the other. In this embodiment, the mounting block 211 is located on the movable plate 21, and the mounting groove 11 is formed in the gas storage tank 1. The mounting block 211 has a strip-shaped structure and a T-shaped cross-section. The shape of the mounting groove 11 matches the shape of the mounting block 211, and the mounting groove 11 is open at both ends of the gas storage tank 1. The mounting block 211 is inserted into the mounting groove 11 through one of its openings. The mounting groove 11 on one side of the movable plate 21 and the mounting block 211 combine to form a stable and flexible connection. This structure allows the movable plate 21 to fit tightly with the gas storage tank 1 during use, preventing loosening due to vibration or other external forces. Meanwhile, the relative movement between the mounting slot 11 and the mounting block 211 ensures convenience during installation or maintenance, allowing users to quickly disassemble or replace the movable plate 21, thus improving the maintainability and ease of use of the entire system.

[0075] To secure the mounting block 211 along the extension direction of the mounting groove 11. For example... Figure 1 As shown, positioning holes 15 are respectively provided on the inner wall of the mounting groove 11 and on the two side walls of the mounting block 211 opposite to the mounting groove 11. Positioning pins 3 are inserted into the positioning holes 15 of the mounting block 211 and the mounting groove 11. After the mounting block 211 is inserted into the mounting groove 11, the positioning pins 3 are inserted into the positioning holes 15 of the mounting groove 11 until the positioning pins 3 are fully inserted into the positioning holes 15 of the mounting block 211, which enhances the stability and accuracy of the connection and ensures that the component still operates reliably under high temperature or high pressure environments. The positioning pins 3 in the positioning holes 15 ensure the precise positioning of the movable plate 21 when it is locked, so that the entire gas release assembly 2 can still maintain good operating condition under high temperature or high pressure environments.

[0076] Furthermore, the length of the positioning post 3 is greater than the sum of the lengths of the positioning holes 15 of the mounting hole and the positioning holes 15 of the mounting groove 11. Therefore, when the positioning post 3 is inserted into the two positioning holes 15, one end of the positioning post 3 is outside the positioning holes 15, making it convenient for the operator to pull it out. In other embodiments, the mounting block 211 can also be set in the gas storage box 1, and the mounting groove 11 can also be opened in the movable plate 21. This embodiment does not specifically limit this.

[0077] Furthermore, a first threaded hole 212 is provided on the movable plate 21, and a second threaded hole 12 is provided on the side of the gas storage tank 1 connected to the movable plate 21. One end of the jet unit 22 is connected to the first threaded hole 212 and the second threaded hole 12 and communicates with the storage cavity. The jet unit 22 is used to jet and release the extinguishing gas in the storage cavity. During the gas release process, the jet unit 22 plays an important role. By providing the first threaded hole 212 and the second threaded hole 12 on the movable plate 21, the jet unit 22 can smoothly pass through the first threaded hole 212 and the second threaded hole 12 and connect with the storage cavity in the gas storage tank 1, ensuring that the extinguishing gas can maintain a high pressure state during release, thereby effectively jetting it to the vicinity of the fire source. The design of the jet unit 22 takes into account the dynamic characteristics of gas flow, so that the extinguishing gas can achieve the best jetting effect instantly. The efficient release mechanism can respond quickly in the early stage of a fire, reduce the risk of fire spread, and ensure the maximization of the fire extinguishing effect.

[0078] In addition, the gas release assembly 2 also includes a gas supply pipe 141. An air inlet 14 is provided at the top of the gas storage tank 1. One end of the gas supply pipe 141 is connected to the storage cavity via the air inlet 14, and the gas supply pipe 141 is used to supply fire extinguishing gas into the storage cavity. The gas supply pipe 141, connected to the storage cavity via the air inlet 14, can promptly replenish the fire extinguishing gas after gas release, maintaining the gas pressure and quality within the storage cavity. This ensures a continuous supply and rapid release of the fire extinguishing gas, improves the overall fire extinguishing effect, and enhances the cabinet-type equipment's response capability in the event of a fire. By providing the air inlet 14 at the top of the gas storage tank 1, the gas supply pipe 141 can promptly replenish the storage cavity with fire extinguishing gas, ensuring the system always has sufficient fire extinguishing gas to cope with emergencies and preventing fire extinguishing failure due to insufficient gas.

[0079] Furthermore, the jet unit 22 of this embodiment is also equipped with an exhaust fan (not shown in the figure) and a closing valve (not shown in the figure). The exhaust fan is used to discharge the fire extinguishing gas in the storage cavity to the cabinet-type equipment, and the closing valve is used to block or guide the discharge direction of the fire extinguishing gas inside the jet unit 22. Since the specific structure of the exhaust fan and the closing valve is prior art, it will not be described in further detail here.

[0080] like Figure 2 and Figure 3 As shown, a protruding plate 13 is provided on the side of the gas storage box 1 away from the gas release component 2. A limiting groove 131 is provided on the inner side of the protruding plate 13 near the gas storage box 1. The adsorption component of this embodiment includes a limiting plate and an adsorption layer. The limiting plate is slidably connected to the limiting groove 131. The adsorption layer is disposed on the end face of the limiting plate and connected to the gas storage box 1 through the limiting plate. The adsorption layer adsorbs at the target position.

[0081] Effective fixing and adsorption functions are achieved through a limiting plate and an adsorption layer. The limiting plate is set on the protruding plate 13 and is slidably connected with the limiting groove 131, allowing the limiting plate to be adjusted and positioned within the limiting groove 131 as necessary, making the installation process more flexible and convenient. The adsorption layer is fixedly connected to the side of the limiting plate away from the groove, ensuring that it can be firmly adsorbed on the target position after installation, thereby achieving a stable connection effect, maintaining stability in various environments, effectively preventing the equipment from shifting when it is running or subjected to external forces, and ensuring the reliability and effectiveness of the overall fire extinguishing system.

[0082] Preferably, the adsorption layer in this embodiment is a suction cup, and multiple suction cups are provided. The multiple suction cups are fixed at equal intervals on the limiting plate. In other embodiments, the adsorption layer can also be Velcro or a vacuum adsorption device, etc. Anything that can achieve the adsorption function can be used, and will not be listed one by one here.

[0083] In some embodiments of this application, when the analysis module is used to establish early warning features based on the historical operating data of the cabinet equipment and the fault data in the historical operating data, the analysis module is further used to obtain the operating temperatures in the historical operating data and the ignition temperature in the fault data.

[0084] The analysis module is also used to establish a linear function of the operating ignition point based on various operating temperatures and the ignition temperature in the fault data. Furthermore, the analysis module is used to determine the first and second preset temperatures for the warning characteristics based on the linear function of the operating ignition point.

[0085] Understandably, the analysis module can extract the operating temperature at various points in time from the historical operating data of the cabinet equipment. This temperature data reflects the temperature change trend of the equipment during long-term operation. Simultaneously, through the ignition temperature in the fault data, the module can identify the key temperature points at which the equipment experiences faults or anomalies, i.e., at what temperatures the equipment poses a fire hazard or fault risk. Based on this, the analysis module establishes a linear function of the operating ignition temperature. This linear function fits the various operating temperatures of the equipment to the ignition temperature in the fault data, forming a mathematical model reflecting the relationship between equipment temperature changes and potential fire risks. This model can predict the possible temperature change trend of the equipment under its current operating state based on the current temperature. In this way, the analysis module can not only monitor the real-time operating status of the equipment but also predict possible future temperature anomalies. Furthermore, based on the warning characteristics determined by the linear function, the analysis module can set different temperature thresholds, including a first preset temperature and a second preset temperature. These two temperature values ​​represent different warning levels. When the real-time temperature of the equipment reaches or approaches the first preset temperature, the analysis module will issue a low-level warning, reminding the user that the equipment is gradually heating up and there is a potential risk. When the equipment temperature approaches or exceeds the second preset temperature, the analysis module triggers a high-level warning signal, indicating that the equipment may be in a high-risk state where a fire is imminent. This dual-layer warning mechanism allows the system to intervene in a timely manner before a fire or equipment failure occurs. The first preset temperature setting allows users to check and adjust the equipment when the temperature is abnormal but has not yet reached a dangerous level, effectively preventing the accident from escalating further. The second preset temperature setting serves as a last line of defense in extreme cases; when the equipment temperature is too high, the system can automatically trigger a fire extinguishing mechanism to prevent a fire. The flexibility and efficiency of this warning mechanism significantly improve the safety and reliability of the equipment. Finally, the linear function model of the analysis module is dynamically adjusted based on long-term operating data of the equipment. This means that the warning threshold setting can be continuously optimized over time, making the predictive ability of the analysis module increasingly accurate. This self-learning and optimization feature provides a higher guarantee for the long-term safe operation of the equipment, avoiding safety hazards caused by environmental changes or equipment aging.

[0086] Specifically, the analysis module is also configured to determine the warning score inside the cabinet equipment based on the relationship between the real-time temperature of the cabinet equipment and the specific gas molecule concentration and the warning characteristics. This includes: the analysis module is also used to determine whether to conduct a warning score evaluation based on the relationship between the real-time temperature of the cabinet equipment and the first preset temperature and the second preset temperature of the warning characteristics, and to determine the warning score during the evaluation.

[0087] When the real-time temperature is lower than the first preset temperature, the analysis module determines not to evaluate the warning score inside the cabinet equipment.

[0088] When the real-time temperature is greater than or equal to the first preset temperature and less than the second preset temperature, the analysis module will evaluate the warning score inside the cabinet equipment and determine the warning score as L1.

[0089] When the real-time temperature is greater than the second preset temperature, the analysis module will evaluate the warning score inside the cabinet equipment and determine the warning score as L2.

[0090] Wherein, the first preset temperature is less than the second preset temperature, and L1 < L2.

[0091] More specifically, when the analysis module determines that the warning score inside the cabinet equipment is Li, i = 1 or 2, the analysis module is further configured to obtain the real-time concentration of a specific gas molecule inside the cabinet equipment, and determine whether to adjust the warning score Li based on the relationship between the real-time concentration and the first preset concentration and the second preset concentration pre-configured by the analysis module.

[0092] When the real-time concentration is less than the first preset concentration, the analysis module determines not to adjust the warning score Li.

[0093] When the real-time concentration is greater than or equal to the first preset concentration and less than the second preset concentration, the analysis module determines the adjustment coefficient based on the concentration difference between the real-time concentration and the first preset concentration, and adjusts the warning score Li according to the adjustment coefficient.

[0094] When the real-time concentration is greater than or equal to the second preset concentration, the analysis module determines the adjustment coefficient as Mmax and adjusts the warning score Li according to the adjustment coefficient Mmax.

[0095] More specifically, when the analysis module determines the adjustment coefficient based on the concentration difference between the real-time concentration and the first preset concentration, it includes: the analysis module is also used to determine the adjustment coefficient based on the relationship between the concentration difference and the first preset concentration difference and the second preset concentration difference pre-configured by the analysis module.

[0096] When the concentration difference is less than the first preset concentration difference, the analysis module determines the adjustment coefficient to be M1.

[0097] When the concentration difference is greater than or equal to the first preset concentration difference and less than the second preset concentration difference, the analysis module determines the adjustment coefficient to be M2.

[0098] When the concentration difference is greater than or equal to the second preset concentration difference, the analysis module determines the adjustment coefficient to be M3. The first preset concentration difference is less than the second preset concentration difference, and M1 < M2 < M3 < Mamx.

[0099] As can be seen, the system determines whether to conduct a warning score assessment by monitoring the relationship between the real-time temperature of the cabinet equipment and the first and second preset temperatures of the warning characteristics. Specifically, when the real-time temperature is lower than the first preset temperature, the system determines that the equipment is within a safe range and therefore does not conduct a score assessment; however, when the temperature reaches or exceeds the first preset temperature, the system assesses the equipment and assigns an L1 score based on the current temperature status. Furthermore, if the real-time temperature exceeds the second preset temperature, the warning score is upgraded to L2, reflecting a higher level of risk. Simultaneously, the analysis module also adjusts the warning score based on the real-time monitored concentration of specific gas molecules. When the real-time concentration is lower than the first preset concentration, the score remains unchanged; while when the concentration is between the first and second preset concentrations, the module calculates the concentration difference and determines an adjustment coefficient based on this value, thus finely adjusting the warning score. If the concentration reaches or exceeds the second preset concentration, the maximum adjustment coefficient Mmax is used for score adjustment. This refined adjustment mechanism ensures that the warning score can reflect the safety status of the equipment in real time, enabling the system to have a higher response capability under different risk conditions.

[0100] In this embodiment, when the central control module is configured to determine the warning level based on the relationship between the warning score inside the cabinet equipment and the pre-configured first preset warning score and second preset warning score, and to determine the injection and release method of the fire extinguishing gas based on the warning level, the central control module is further configured to determine the warning level based on the relationship between the warning score and the first preset warning score and the second preset warning score, and to determine the exhaust fan flow rate and the opening degree of the closing valve based on the warning level.

[0101] When the warning score is less than the first preset warning score, the central control module determines the warning level to be low, and determines the exhaust fan flow rate to be Q1 and the closing valve opening degree to be A1.

[0102] When the warning score is greater than or equal to the first preset warning score and less than the second preset warning score, the central control module determines the warning level to be medium and determines the exhaust fan flow rate to be Q2 and the closing valve opening degree to be A2.

[0103] When the warning score is greater than or equal to the second preset warning score, the central control module determines the preset level to be high, and sets the exhaust fan flow rate to Q3 and the closing valve opening degree to A3. Specifically, the first preset warning score is less than the second preset warning score, and Q1 < Q2 < Q3 < 100%, A1 < A2 < A3 < 100%.

[0104] In the above embodiments, the temperature detection module and odor detection module can continuously monitor the interior of the cabinet-type equipment. This not only detects temperature changes inside the equipment but also detects the concentration of specific gas molecules, such as harmful gases released in the early stages of combustion, to promptly identify potential fire hazards. This multi-sensor collaborative working mode significantly improves the sensitivity and accuracy of fire monitoring, reducing the probability of fires. Secondly, the analysis module establishes early warning characteristics for the equipment by utilizing historical operating and fault data of the cabinet-type equipment. This data-driven model enables the fire extinguishing patch to not only identify early signs of fire but also to provide an early warning score based on real-time data, reflecting the current fire risk level faced by the equipment. This early warning mechanism effectively avoids the limitations of traditional equipment that relies excessively on temperature thresholds, ensuring earlier fire warnings. Furthermore, the central control module automatically selects the appropriate fire extinguishing gas release method according to different warning levels. This graded response mechanism can accurately handle fire hazards of varying severity. Finally, the design of the adsorption component allows the fire extinguishing patch to be easily installed on the surface of the cabinet-type equipment, while the grooved structure ensures its firmness. This simple and reliable mounting method not only simplifies the installation process but also reduces the maintenance burden on operation and maintenance personnel, thereby improving the practicality of the equipment.

[0105] like Figure 4 As shown, this embodiment also provides a fire extinguishing method for cabinet-type equipment. This fire extinguishing method for cabinet-type equipment is based on the smart fire extinguishing sticker for cabinet-type equipment described above, and includes the following steps:

[0106] Step S100: Obtain the real-time temperature inside the cabinet equipment and the concentration of specific gas molecules inside the cabinet equipment.

[0108] Step S300: Determine the warning level based on the relationship between the warning score inside the cabinet equipment and the pre-configured first and second preset warning scores, and determine the injection and release method of the fire extinguishing gas based on the warning level.
