[0002] In existing data center fire protection systems, to ensure fire suppression, fire-fighting actions are often initiated as soon as there is a fire risk. However, in reality, overreacting fire intervention can cause unnecessary power outages or system shutdowns, thereby increasing the risk of data loss and wasting additional fire-fighting resources. Summary of the Invention

[0056] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0057] To better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indicators will also change accordingly. It should be understood that although the steps in the flowcharts of the embodiments of this application are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0059] In existing data center fire protection systems, to ensure fire suppression, fire-fighting actions are often initiated as soon as there is a fire risk. However, in reality, overreacting fire intervention can cause unnecessary power outages or system shutdowns, thereby increasing the risk of data loss and wasting additional fire-fighting resources.

[0060] Therefore, refer to Figure 1 This application proposes a smart fire protection method for a data center, wherein the data center has multiple server racks, and the multiple server racks include at least two different types of server racks; the smart fire protection system for the data center includes a control device for executing the smart fire protection method for the data center, the method comprising:

[0061] Step S100: Obtain the operating status information corresponding to the cabinet;

[0062] In this embodiment, the control device includes a memory, a processor, and the intelligent fire protection method for data centers stored in the memory and executable on the processor. Optionally, the control device can be implemented using a controller, such as an MCU, DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), PLC, or SOC (System on Chip).

[0063] Optionally, in one embodiment, the operating condition information can be at least one of temperature information, flame information, smoke information, and self-extinguishing capability. The intelligent fire protection system may be equipped with flame monitoring sensors, such as flame image monitoring sensors, to monitor flame images in the data center. Similarly, the intelligent fire protection system may also be equipped with smoke sensors, such as electrochemical smoke sensors and smoke image sensors, to monitor smoke concentration in the data center. The control device can obtain flame and smoke information of the server rack through the flame monitoring sensors and smoke sensors. The control device can also establish data exchange with the server rack via wireless or wired communication to confirm whether the current server rack has self-extinguishing capability, i.e., whether it has a self-extinguishing device inside.

[0064] Furthermore, it is understood that data centers contain different types of server racks, and each type of rack has its own unique operating condition information. This unique operating condition information is also important for subsequent fire risk assessment. Therefore, to improve the accuracy of fire risk assessment for different types of server racks, in one embodiment, reference is made to... Figure 2 The step of obtaining the operating status information corresponding to the cabinet further includes: step S310, obtaining the corresponding operating status information of the cabinet based on the cabinet type; wherein, the cabinet type includes power distribution cabinet, UPS cabinet and IT cabinet; step S310, obtaining the corresponding operating status information of the cabinet based on the cabinet type includes:

[0065] Optionally, when the cabinet type is a power distribution cabinet, the operating condition information further includes: total output power; the temperature information of the power distribution cabinet includes at least: wire harness connector temperature. In this embodiment, the power distribution cabinet plays a power distribution role in the data center, for example, converting the connected mains power and outputting different voltages to other cabinets to provide power to them. Therefore, power distribution cabinets have a large number of connecting wire harnesses, and many of these harnesses are used for transmitting electrical energy. It is understood that the temperature of these power transmission harnesses, especially at the connectors, is generally higher. Similarly, since the power distribution cabinet is mainly responsible for power output, its total output power will be higher than that of other types of cabinets. In this application, temperature sensors can be installed at multiple wire harness connector locations in the power distribution cabinet, for example, NTC temperature sensor probes can be installed inside / outside the wire harness connectors to detect the temperature of the wire harness connectors and transmit the results back to the control device.

[0066] Optionally, when the cabinet type is a UPS cabinet, the operating condition information further includes: the air pressure inside the battery module; the UPS operating condition information includes at least: the battery module temperature; in this embodiment, the UPS cabinet is a backup power cabinet, which houses battery modules, such as lithium battery modules, used as backup power. The control device can establish a data interconnection with the UPS cabinet via wireless or wired communication to obtain the battery module temperature and air pressure inside the battery module from the battery management module in the battery module within the UPS cabinet.

[0067] Optionally, when the rack type is an IT rack, the operating condition information further includes: airflow velocity inside the rack and air pressure distribution information inside the rack; the operating condition information of the IT rack includes at least: coolant temperature. In this embodiment, IT racks generally house servers, network devices, and storage devices to provide data transmission and storage. It is understood that the operating temperature of the circuitry in IT racks is generally high; therefore, to ensure the heat dissipation performance of the internal circuitry, additional heat dissipation devices, such as ventilation and coolant cooling systems, are often installed on the IT rack.

[0068] Step S200: Based on the operating condition information and cabinet type of the cabinet, generate the fire risk corresponding to the cabinet;

[0069] Step S300: If, based on the fire risk, it is determined that the cabinet requires fire intervention, then, based on the cabinet type, perform the corresponding fire-fighting actions on the cabinet.

[0070] Optionally, in one embodiment, the type of the cabinet is a power distribution cabinet, and the step of generating the fire risk corresponding to the cabinet based on the cabinet's operating condition information and cabinet type includes:

[0071] If the temperatures of the multiple wiring harness connectors are within the safe temperature range of the connectors, and the total output power is less than the alarm power, and it is determined from the flame information and smoke information that there is no open flame or smoke in the power distribution cabinet, then the fire risk of the power distribution cabinet is determined to be that there is no need for fire intervention.

[0072] If the total output power is greater than the alarm power for a first duration, or the number of wire harness connectors with temperatures within a first connector temperature range reaches a first quantity, or the open flame area of ​​the distribution cabinet is less than a first area based on the flame information, or the smoke concentration of the distribution cabinet is less than a first concentration based on the smoke information, then if the distribution cabinet has self-extinguishing capability, the fire risk of the distribution cabinet is determined to be that there is no need for fire intervention; if the distribution cabinet does not have self-extinguishing capability, the fire risk of the distribution cabinet is determined to be that there is a need for fire intervention.

[0073] If the temperature of any of the wire harness connectors is within the second connector temperature range, or if the open flame area of ​​the power distribution cabinet is determined to reach the first area based on the flame information, or if the smoke concentration of the power distribution cabinet is determined to reach the first concentration based on the smoke information, then the fire risk of the power distribution cabinet is determined to require fire intervention; wherein, the minimum value of the second connector temperature range is greater than the maximum value of the first connector temperature range, and the minimum value of the first connector temperature range is greater than the maximum value within the connector safety temperature range;

[0074] The intelligent fire protection system also includes a gas extinguishing device. The step of controlling the corresponding fire-fighting equipment to perform corresponding fire-fighting actions on the cabinet based on its cabinet type includes:

[0075] The gas extinguishing device is controlled to spray gaseous extinguishing agent onto the power distribution cabinet, and the power distribution cabinet is controlled to be in a stopped working state, and the UPS cabinet is controlled to be in a power output state.

[0076] In this embodiment, the safe temperature range, alarm power, first duration, first quantity, first area, first concentration, and second connector temperature range can be set by the R&D personnel according to their needs. It is understood that for cabinets with self-extinguishing capabilities, if the current fire situation is only minor, the control device will not immediately initiate fire suppression actions. Instead, the self-extinguishing device within the cabinet will be prioritized to extinguish the fire, thereby reducing excessive reaction from the fire suppression system. Gaseous extinguishing agents may include heptafluoropropane, perfluorohexanone, etc. While controlling the gaseous extinguishing device to spray the extinguishing agent onto the power distribution cabinet, the control device will also control the burning power distribution cabinet to stop outputting power and control the UPS cabinet to start supplying power to ensure the continuity and stability of the IT cabinet's operation.

[0077] Optionally, in one embodiment, the type of the cabinet is a UPS cabinet, and the step of generating the fire risk corresponding to the cabinet based on the cabinet's operating condition information and cabinet type includes:

[0078] If the air pressure inside the battery module is within a safe air pressure range, and the temperature of the battery module is within a safe battery temperature range, and if it is determined from the flame information and smoke information that there is no open flame or smoke in the UPS cabinet, then the fire risk of the UPS cabinet is determined to be that there is no need for fire intervention.

[0079] If the air pressure inside the battery module is within a first air pressure range, or the temperature of the battery module is within a first battery temperature range, or the open flame area of ​​the UPS cabinet is determined to be less than a first area based on the flame information, or the smoke concentration of the UPS cabinet is determined to be less than a first concentration based on the smoke information, then if the UPS cabinet has self-extinguishing capability, the fire risk of the UPS cabinet is determined to be that there is no need for fire intervention; if the UPS cabinet does not have self-extinguishing capability, the fire risk of the UPS cabinet is determined to be that there is a need for fire intervention.

[0080] When the air pressure inside the battery module is within a second air pressure range, or the battery module temperature is within a second battery temperature range, or the open flame area of ​​the UPS cabinet reaches a first area based on the flame information, or the smoke concentration of the UPS cabinet reaches a first concentration based on the smoke information, the fire risk of the UPS cabinet is determined to require fire intervention; wherein, the minimum value of the second battery temperature range is greater than the maximum value of the first battery temperature range, and the minimum value of the first battery temperature range is greater than the maximum value within the battery safety temperature range; the minimum value of the second air pressure range is greater than the maximum value of the first air pressure range, and the minimum value of the first air pressure range is greater than the maximum value of the safety air pressure range;

[0081] The intelligent fire protection system also includes a gas extinguishing device and a fine water mist spray system. The step of controlling the corresponding fire protection equipment to perform corresponding fire protection actions on the cabinet based on its cabinet type includes:

[0082] The gas extinguishing device is controlled to spray gaseous extinguishing agent onto the UPS cabinet, and when it is determined from the flame information that there is no open flame in the UPS cabinet, the fine water mist spraying system is controlled to spray fine water mist onto the battery modules in the UPS cabinet to reduce the temperature of the battery modules.

[0083] In addition, the connection between the battery module and the circuit module in the UPS cabinet is kept disconnected.

[0084] In this embodiment, the safe air pressure range, battery safe temperature range, first air pressure range, first battery temperature range, first area, first concentration, second air pressure range, and second battery temperature range can be set by the R&D personnel according to their needs. It is understood that for cabinets with self-extinguishing capabilities, if the current fire situation is only minor, the control device will not immediately execute fire-fighting actions. Instead, the self-extinguishing device within the cabinet will be prioritized to extinguish the fire, thereby reducing excessive reaction of the fire-fighting action. Gas extinguishing agents may include heptafluoropropane, perfluorohexanone, etc. When the control device executes fire-fighting actions on the UPS cabinet, it will disconnect the path between the battery module and the UPS circuit module in the UPS cabinet to achieve electromagnetic isolation of the battery module. Simultaneously, because the UPS cabinet contains lithium batteries, the fire will be more intense than other types of cabinets when it catches fire. Therefore, the control device will first control the gas extinguishing device to start spraying gas extinguishing agents, such as first spraying perfluorohexanone to suppress the runaway thermal chain reaction, and then spraying fire-extinguishing aerosols to extinguish the open flame. In the absence of open flames in the UPS cabinet, the fine water mist spray system will also be controlled to spray fine water mist onto the battery modules in the UPS cabinet to reduce the temperature of the battery modules and thus prevent reignition.

[0085] Furthermore, based on the aforementioned UPS-type cabinet, in one embodiment, generating the corresponding fire risk for the cabinet based on its operating condition information and cabinet type further includes:

[0086] If the air pressure inside the battery module is within a first air pressure range, or the temperature of the battery module is within a first battery temperature range, or the open flame area of ​​the UPS cabinet is determined to be less than a first area based on the flame information, or the smoke concentration of the UPS cabinet is determined to be less than a first concentration based on the smoke information, then if the UPS cabinet does not have self-extinguishing capability and the battery module does have self-extinguishing capability, then the fire risk of the UPS cabinet is determined to require fire intervention.

[0087] In this embodiment, it is understood that some UPS cabinets may not have self-extinguishing capabilities, but the battery modules within them may. Therefore, if the control device determines that the battery module has self-extinguishing capabilities during communication with the battery module, it will refrain from executing fire suppression actions on the UPS cabinet under the aforementioned operating conditions, thereby further reducing the risk of overreaction in the fire suppression action.

[0088] Optionally, in one embodiment, the cabinet type is an IT cabinet, and generating the corresponding fire risk based on the cabinet's operating condition information and cabinet type includes:

[0089] If the airflow velocity inside the cabinet is within the safe airflow velocity range, and the air pressure distribution inside the cabinet is determined to be uniform based on the air pressure distribution information inside the cabinet, and the coolant temperature is within the safe coolant temperature range, and the IT cabinet is determined to be free of open flame and smoke based on the flame information and the smoke information, then the fire risk of the IT cabinet is determined to be that there is no need for fire intervention.

[0090] If the airflow velocity inside the cabinet is within a first airflow velocity range, or if the air pressure distribution inside the cabinet is determined to be uneven based on the air pressure distribution information inside the cabinet, or if the coolant temperature is within a first coolant temperature range, or if the open flame area of ​​the IT cabinet is determined to be smaller than a first area based on the flame information, or if the smoke concentration of the IT cabinet is determined to be smaller than a first concentration based on the smoke information, then if the IT cabinet has self-extinguishing capability, the fire risk of the IT cabinet is determined to be that there is no need for fire intervention; if the IT cabinet does not have self-extinguishing capability, the fire risk of the IT cabinet is determined to be that there is a need for fire intervention.

[0091] If the airflow velocity inside the cabinet is within a second airflow velocity range, or the coolant temperature is within a second coolant temperature range, or the open flame area of ​​the IT cabinet is determined to reach a first area based on the flame information, or the smoke concentration of the IT cabinet is determined to reach a first concentration based on the smoke information, then the fire risk of the IT cabinet is determined to require fire intervention; wherein, the minimum value of the safe airflow velocity range is greater than the maximum value of the first airflow velocity range, the minimum value of the first airflow velocity range is greater than the maximum value of the second airflow velocity range, the minimum value of the second coolant temperature range is greater than the maximum value of the coolant temperature range, and the minimum value of the first battery temperature range is greater than the maximum value within the safe coolant temperature range;

[0092] The intelligent fire protection system includes a gas extinguishing device and an active temperature control device installed on the IT cabinet. The step of controlling the corresponding fire protection equipment to perform corresponding fire protection actions on the cabinet based on its type includes:

[0093] The gas extinguishing device is controlled to spray gaseous extinguishing agent onto the IT cabinet, and when it is determined from the flame information that there is no open flame in the IT cabinet, the active temperature control device is controlled to start working to reduce the temperature of the IT cabinet.

[0094] In this embodiment, the safe airflow velocity range, the first airflow velocity range, the coolant safe temperature range, the first coolant temperature range, the first area, the first concentration, the second airflow velocity range, and the second coolant temperature range can be preset by the R&D personnel according to requirements. It is understood that for server racks with self-extinguishing capabilities, if the current fire situation is only minor, the control device will not immediately execute fire-fighting actions, prioritizing the self-extinguishing devices within the rack to extinguish the fire, thereby reducing overreaction of the fire-fighting actions. Furthermore, the intelligent fire-fighting system can also install gas flow sensors and gas pressure sensors in the IT server rack. It is understood that because IT server racks operate at high temperatures, they are equipped with active cooling devices, such as fans. Therefore, when the temperature of the IT server rack rises due to a fire, the airflow velocity inside slows down due to the accumulation of hot air, and the air pressure inside the IT server rack also becomes uneven due to the accumulation of hot air. During the fire suppression process for the IT cabinet, the control device first activates the gas extinguishing system to spray extinguishing agents, such as heptafluoropropane and perfluorohexanone, onto the cabinet. Then, because the IT cabinet remains operational even in the event of a localized fire, the control device immediately activates active temperature control devices, such as water cooling, air cooling, or semiconductor cooling systems, to lower the cabinet's temperature and prevent reignition, effectively ensuring the stability and reliability of the IT cabinet's operation.

[0095] Step S400: If, based on the fire risk, it is determined that the cabinet does not require fire intervention, the intelligent fire protection system is controlled to be in standby mode.

[0096] It is understood that if, based on the above-described embodiment process, it is determined that the current cabinet does not require fire intervention, the fire-fighting equipment in the intelligent fire protection system of this application will not be controlled to perform fire-fighting actions on the cabinet. Furthermore, it is understood that for the aforementioned cabinets with self-extinguishing devices, the control device can also establish communication with the cabinet to obtain the operating status of its self-extinguishing device. If, after the self-extinguishing device is activated, the control device detects a trend of the cabinet becoming more susceptible to fire intervention based on the cabinet's operating condition information, it will immediately perform the corresponding fire-fighting actions. For example, for the aforementioned power distribution cabinet, although the temperature of the wire harness connectors of its multiple harnesses is within the first connector temperature range, the temperature is increasing without decreasing. Therefore, the control device will determine that the self-extinguishing device of the current power distribution cabinet is insufficient to meet the fire-fighting requirements and will immediately perform the corresponding fire-fighting actions on the power distribution cabinet. In this way, the fire safety of the cabinets in the data center can be further guaranteed. Compared with delayed judgment, the judgment based on the changing trend can further improve the response speed to fire intervention of the cabinets. This ensures that if the self-extinguishing device fails or the fire extinguishing performance is insufficient, the smart fire protection method applied to the data center can intervene more quickly to ensure the safety of the data center cabinets.

[0097] This application proposes a smart fire protection method for data centers. The data center has multiple server racks, including at least two different types of racks. The smart fire protection system for the data center includes a control device for executing the smart fire protection method. The method includes: acquiring the operating status information of the corresponding server racks; generating the fire risk of the corresponding server rack based on the operating status information and rack type; if, based on the fire risk, it is determined that the server rack requires fire intervention, then, based on the rack type, performing corresponding fire protection actions on the server rack; if, based on the fire risk, it is determined that the server rack does not require fire intervention, then controlling the fire protection equipment to be in standby mode. Thus, this application assesses the fire risk of server racks in the data center and determines whether to execute fire protection actions based on the assessment results to reduce overreaction, thereby effectively improving the accuracy of the data center fire protection system's execution of fire protection actions, reducing overreaction, and ultimately reducing the consumption and waste of fire protection resources.

[0098] It is important to understand that the intelligent fire protection system described in this application is installed in a data center. Furthermore, as mentioned above, during fire suppression operations, some server racks will not be powered off; even in racks where a fire has occurred, some circuits will remain operational. For example, IT server racks generally try to maintain their operational status. Therefore, the operating current and the current working environment of the rack will also affect the fire extinguishing effect of the extinguishing agent.

[0099] Therefore, refer to Figure 3 In one embodiment of this application, the intelligent fire protection system includes a gas extinguishing device, and the step of controlling the corresponding fire protection equipment to perform corresponding fire protection actions on the cabinet based on the cabinet type further includes:

[0100] Step S310: Obtain the operating current and ambient humidity of the equipment in the cabinet;

[0101] Step S320: Based on the operating current and / or the ambient humidity, and according to the gas concentration setting logic, generate a corresponding first gas concentration;

[0102] Step S330: Control the gas extinguishing agent sprayed by the gas extinguishing device to a corresponding concentration according to the first gas concentration; wherein, the gas concentration setting logic includes: the operating current is positively correlated with the first gas concentration, and the ambient humidity is positively correlated with the first gas concentration.

[0103] In this embodiment, the control device can communicate with the devices in the cabinet via wired or wireless communication to obtain the operating current of the cabinet devices. Simultaneously, the intelligent fire protection system can also incorporate multiple humidity sensors in its data. The control device is electrically connected to these humidity sensors to obtain the ambient humidity detected by the sensors. The control device determines the ambient humidity of the cabinet based on at least one humidity sensor located around the cabinet where the fire protection action needs to be performed. For example, the ambient humidity can be determined based on the average humidity detected by multiple humidity sensors around the cabinet.

[0104] Understandably, for gas extinguishing devices, the concentration of the extinguishing agent affects its extinguishing effect. A higher operating current results in a higher cabinet temperature, thus requiring a higher concentration of the extinguishing agent. Similarly, humidity affects the actual extinguishing effect of the extinguishing agent; therefore, higher humidity necessitates a higher concentration. The control device can be pre-configured with a preset operating current-gas concentration mapping table and / or an ambient humidity-gas concentration mapping table. Based on the obtained operating current and / or ambient humidity, and the aforementioned mapping tables, the control device determines the first gas concentration. It is understandable that, considering both ambient humidity and operating current, the higher of the two gas concentrations can be used as the first gas concentration. Then, the control device controls the gas extinguishing device to spray the corresponding concentration of extinguishing agent according to the first gas concentration. Through this setup, the effectiveness and response speed of the intelligent fire protection system in executing fire-fighting actions in the data center can be effectively improved, thereby extinguishing the fire source as quickly as possible and further enhancing the fire safety reliability of the data center.

[0105] It is important to understand that in practice, especially after the smart fire protection system in a data center activates its fire suppression system, the burning of server racks or the residue of fire extinguishing agents can affect the data center environment, which may in turn affect the subsequent use of equipment inside the racks or the maintenance personnel who enter the data center later.

[0106] Therefore, in one embodiment of this application, reference is made to Figure 4 The intelligent fire protection method applied to data centers also includes a neutralizing agent spraying device; the method further includes: step S500, after completing the fire protection action on the cabinet, and if it is determined based on the fire risk that no fire protection action needs to be performed on the cabinet, the corresponding post-disaster handling action is performed based on the cabinet type of the cabinet.

[0107] In this embodiment, optionally, in one embodiment, the post-disaster handling action can be a functional assessment of the cabinet after firefighting actions have been performed. In one example, refer to Figure 5 The actions taken to perform corresponding disaster recovery procedures based on the cabinet type include:

[0108] Step S520: If the cabinet type is an IT cabinet, obtain the amount of copper ion deposition on the motherboard in the IT cabinet, and if the amount of copper ion deposition is greater than the preset alarm deposition amount, control the IT cabinet to be in a shutdown state and trigger an alarm.

[0109] In this embodiment, the intelligent fire protection system can also be equipped with a copper ion emission monitor. This device can be directly installed in the IT cabinet and communicate with the control device. It is understood that IT cabinets are generally not in a shutdown or power-off state. However, the high temperature or chemicals generated by combustion may affect the motherboard inside the cabinet, leading to the emission of a large amount of copper ions. This emission can severely impact the motherboard's functionality and may even cause secondary accidents. Therefore, after the control device has completed the fire protection actions on the IT cabinet, and based on the fire risk assessment process described above, determines that further fire protection actions are not necessary, it will use the copper ion emission monitor to determine that the copper ion emission level exceeds the preset alarm threshold. If this occurs, the control device will then determine that the motherboard cannot continue to perform its functions. The control device will then directly shut down or power off the IT cabinet and alert maintenance personnel via a remote alarm system, effectively preventing secondary accidents caused by the IT cabinet continuing to operate in an abnormal state. In addition, if the amount of copper ion deposition in the IT cabinet does not reach the preset alarm deposition amount, the control device will maintain the current state of the IT cabinet, such as keeping it in working condition.

[0110] Alternatively, in another embodiment, post-disaster recovery actions may also involve treating the combustion products. In one example, refer to... Figure 5 The intelligent fire protection system also includes a neutralizing agent sprayer; the corresponding post-disaster handling actions based on the cabinet type include:

[0111] Step S510: If the cabinet type is a UPS cabinet or the cabinet is equipped with a battery module, control the neutralizing agent sprayer in the area where the cabinet is located to spray alkaline aerosol.

[0112] In this implementation, neutralizing agent sprayers can be directly installed inside UPS cabinets or cabinets with battery modules (such as IT cabinets with battery modules), or around such cabinets. It is understood that for cabinets with battery modules, the existing battery modules are generally lithium-ion modules. Lithium-ion batteries produce acidic substances when burned, which can corrode circuit boards or cables within the cabinet. Therefore, when the control device determines, based on the aforementioned fire risk assessment, that the cabinet does not require further fire intervention, it will control the neutralizing agent sprayers at the appropriate locations to spray alkaline aerosols, such as nano-sized alkaline aerosols, to neutralize the acidic substances produced by the burning lithium-ion batteries. This effectively improves the safety and stability of cabinets in the data center after a fire, reducing the probability of secondary accidents following a fire.

[0113] Optionally, in another embodiment, post-disaster handling actions can also target the disposal of extinguishing agents. It is understood that in actual firefighting situations, a sufficient amount of extinguishing agent is often released to ensure the efficiency and completeness of extinguishing. Therefore, in the event of a disaster, a certain amount of extinguishing agent will inevitably remain in the data center's server racks. Some of this remaining extinguishing agent, at higher concentrations, can be harmful to humans, such as heptafluoropropane gas extinguishing agents. Therefore, the intelligent fire protection system can also be equipped with corresponding neutralizing agent sprayers. For example, sodium acrylate gas can be stored alongside heptafluoropropane gas. The control device can use the neutralizing agent sprayer to spray a corresponding dose of sodium acrylate gas according to a preset neutralization ratio (set by the R&D personnel) and the amount of remaining heptafluoropropane detected by the heptafluoropropane sensor to achieve neutralization. In this way, the impact of residual extinguishing agents on subsequent maintenance personnel can be effectively reduced.

[0114] This application also proposes a smart fire protection system for data centers, characterized in that the system includes a control device, the control device including a memory, a processor, and a smart fire protection method for data centers as described above, stored in the memory and executable on the processor.
