[0032] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0033] Please refer to Figure 2 as well as Figure 3 , a control method for a fire protection system, comprising the steps of:

[0034] S1. Obtain a fire signal, locate the fire area according to the fire signal, and spray the fire agent on the fire area of ​​the energy storage system or the data center based on multiple fire agent bottle groups;

[0035] The energy storage system and the data center are connected to the same fire protection system via different fire protection pipelines;

[0036] The amount of fire-fighting agent in the fire-fighting agent bottle set is set according to the standard fire-fighting agent usage:

[0037] Sa. Obtaining fire protection system parameters and specification data of an energy storage system and a data center, wherein the energy storage system and the data center are connected to the same fire protection system through different fire protection pipelines;

[0038] Sb. According to the specification data and the fire protection system parameters, the larger value of the fire protection agent dosage required by the energy storage system and the data center is calculated and selected, and set as the standard fire protection agent usage.

[0039] From the above description, it can be seen that the beneficial effects of the present invention are: a control method of a fire protection system of the present invention, a unified fire protection system provides fire protection support for an energy storage system and a data center, a plurality of fire protection agent bottles are provided in the fire protection system, and the amount of fire protection agent in each fire protection agent bottle is determined according to the actual conditions of the energy storage system and the data center, by calculating the larger amount of the two, to ensure that the spraying amount of the fire extinguishing agent meets the fire protection requirements of the two. Compared with traditional solutions, more full and flexible utilization of fire protection resources is achieved, more efficient configuration, and better safety and economy are achieved.

[0040] Furthermore, the specification data includes the net volume V and the fire extinguishing design concentration C of a single protection zone;

[0041] The fire protection system parameters include the mass volume fraction S of the fire protection agent at standard atmospheric pressure and minimum ambient temperature;

[0042] The calculation of the fire-fighting agent dosage is specifically as follows:

[0043]

[0044] Wherein, W is the weight of the agent and K is the preset altitude correction factor.

[0045] From the above description, it can be known that the weight of the required fire-fighting agent is calculated according to the net volume of a single protection zone, the fire-extinguishing design concentration and the mass volume fraction of the fire-fighting agent at standard atmospheric pressure and minimum ambient temperature.

[0046] Further, step Sb comprises the steps of:

[0047] Sb1. Determine the energy storage system and the data center, based on the specification data, whichever requires a larger amount of fire-fighting agent, and obtain standard data;

[0048] Sb2. Calculate the required amount of fire-fighting agent based on the fire-fighting system parameters and the specification data of the standard data party to obtain the standard fire-fighting agent usage.

[0049] From the above description, it can be known that the side with a larger amount of fire-fighting agent required is first determined according to the specification data, so that only the amount of agent required by the side with a larger amount of agent required is required, which reduces the use of computing resources.

[0050] Further, step Sb1 comprises the steps of:

[0051] According to the specification data, the judgment parameter z is calculated:

[0052]

[0053] Among them, C1 is the fire extinguishing design concentration of the energy storage system, C ’ 1 is the fire extinguishing design concentration of the data center, V1 is the net volume of a single protection zone in the energy storage system, and V'1 is the net volume of a single protection zone in the data center;

[0054] The determination parameter z is determined. If z≥1, it is determined that the amount of fire-fighting agent required by the data center is larger. Otherwise, it is determined that the amount of fire-fighting agent required by the energy storage system is larger.

[0055] From the above description, it can be seen that considering the calculation method of the required measurement, the above steps can more quickly determine which side of the data center and the energy storage system requires a larger amount of fire-fighting agent.

[0056] Further, step S1 comprises the steps of:

[0058] S12, determining a fire protection zone where a fire exists according to the fire signal, starting a fire-fighting agent bottle group, and spraying the fire-fighting agent to the fire protection zone through a fire-fighting pipeline;

[0059] S13, after a preset delay, judging whether the fire is extinguished according to the fire signal, if not, starting the next fire-fighting agent bottle group to spray the fire-fighting agent to the fire protection area;

[0060] S14. Repeat step S13 until there is no fire signal and the fire is deemed to be extinguished.

[0061] From the above description, it can be seen that when spraying fire-fighting agents, after a preset delay after spraying, it is judged again whether the fire is extinguished. If not, the next fire-fighting agent bottle group can be mobilized to spray the fire-fighting agent, so that when the fire cannot be extinguished by one spraying, there are follow-up measures, which is safer and more reliable.

[0062] Please refer to Figure 1 , a fire fighting system, comprising a plurality of fire fighting agent bottle groups, each of which is connected to a fire fighting pipe, and is connected to each cabinet of a data center and each energy storage cabinet of an energy storage system through the fire fighting pipe and a valve, and each cabinet and energy storage cabinet is used as a protection zone;

[0063] The amount of fire fighting agent in each fire fighting agent bottle group is determined by the standard fire fighting agent usage calculated by the following steps:

[0064] Sa. Obtaining fire protection system parameters and specification data of an energy storage system and a data center, wherein the energy storage system and the data center are connected to the same fire protection system through different fire protection pipelines;

[0065] Sb. Calculate and select the larger value of the fire-fighting agent dosage required by the energy storage system and the data center according to the specification data and the fire-fighting system parameters, and set it as the standard fire-fighting agent usage;

[0066] The control mechanism includes a control mechanism, which is connected to each fire-fighting agent bottle group, valve and detector in each protection zone, and can control the opening and closing of the fire-fighting agent bottle group and valve, and implements the following steps through the control mechanism:

[0067] S1. Obtain a fire signal, locate a fire area according to the fire signal, and spray fire-fighting agents on the fire area of ​​the energy storage system or the data center based on a plurality of fire-fighting agent bottle groups.

[0068] From the above description, it can be seen that the beneficial effects of the present invention are: a control method of a fire protection system of the present invention, a unified fire protection system provides fire protection support for an energy storage system and a data center, a plurality of fire protection agent bottles are provided in the fire protection system, and the amount of fire protection agent in each fire protection agent bottle is determined according to the actual conditions of the energy storage system and the data center, by calculating the larger amount of the two, to ensure that the spraying amount of the fire extinguishing agent meets the fire protection requirements of the two. Compared with traditional solutions, more full and flexible utilization of fire protection resources is achieved, more efficient configuration, and better safety and economy are achieved.

[0069] Furthermore, the specification data includes the net volume V and the fire extinguishing design concentration C of a single protection zone;

[0070] The fire protection system parameters include the mass volume fraction S of the fire protection agent at standard atmospheric pressure and minimum ambient temperature;

[0071] The calculation of the fire-fighting agent dosage is specifically as follows:

[0072]

[0073] Wherein, W is the weight of the agent and K is the preset altitude correction factor.

[0074] From the above description, it can be known that the weight of the required fire-fighting agent is calculated according to the net volume of a single protection zone, the fire-extinguishing design concentration and the mass volume fraction of the fire-fighting agent at standard atmospheric pressure and minimum ambient temperature.

[0075] Further, step Sb comprises the steps of:

[0076] Sb1. Determine the energy storage system and the data center, based on the specification data, whichever requires a larger amount of fire-fighting agent, and obtain standard data;

[0077] Sb2. Calculate the required amount of fire-fighting agent based on the fire-fighting system parameters and the specification data of the standard data party to obtain the standard fire-fighting agent usage.

[0078] From the above description, it can be known that the side with a larger amount of fire-fighting agent required is first determined according to the specification data, so that only the amount of agent required by the side with a larger amount of agent required is required, which reduces the use of computing resources.

[0079] Further, step Sb1 comprises the steps of:

[0080] According to the specification data, the judgment parameter z is calculated:

[0081]

[0082] Among them, C1 is the fire extinguishing design concentration of the energy storage system, C ’ 1 is the fire extinguishing design concentration of the data center, V1 is the net volume of a single protection zone in the energy storage system, and V'1 is the net volume of a single protection zone in the data center;

[0083] The determination parameter z is determined. If z≥1, it is determined that the amount of fire-fighting agent required by the data center is larger. Otherwise, it is determined that the amount of fire-fighting agent required by the energy storage system is larger.

[0084] From the above description, it can be seen that considering the calculation method of the required measurement, the above steps can more quickly determine which side of the data center and the energy storage system requires a larger amount of fire-fighting agent.

[0085] Further, step S1 comprises the steps of:

[0086] S11, receiving a fire signal, where the fire signal is generated by detectors disposed in each protection zone of the data center and the energy storage system;

[0087] S12, determining a fire protection zone where a fire exists according to the fire signal, starting a fire-fighting agent bottle group, and spraying the fire-fighting agent to the fire protection zone through a fire-fighting pipeline;

[0088] S13, after a preset delay, judging whether the fire is extinguished according to the fire signal, if not, starting the next fire-fighting agent bottle group to spray the fire-fighting agent to the fire protection area;

[0089] S14. Repeat step S13 until there is no fire signal and the fire is deemed to be extinguished.

[0090] From the above description, it can be seen that when spraying fire-fighting agents, after a preset delay after spraying, it is judged again whether the fire is extinguished. If not, the next fire-fighting agent bottle group can be mobilized to spray the fire-fighting agent, so that when the fire cannot be extinguished by one spraying, there are follow-up measures, which is safer and more reliable.

[0091] A control method and a fire protection system of the present invention are suitable for fire protection system design, and are particularly suitable for the design of a flexible fire protection control system after a data center is equipped with an energy storage system.

[0092] Please refer to Figures 1 to 4 , Embodiment 1 of the present invention is:

[0093] A method for controlling a fire protection system comprises the following steps:

[0094] S1. Obtain a fire signal, locate the fire area according to the fire signal, and spray the fire agent on the fire area of ​​the energy storage system or the data center based on multiple fire agent bottle groups;

[0095] The energy storage system and the data center are connected to the same fire protection system via different fire protection pipelines;

[0096] Please refer to Figure 2 , step S1 comprises the steps of:

[0097] S11, receiving a fire signal, where the fire signal is generated by detectors disposed in each protection zone of the data center and the energy storage system;

[0098] S12, determining a fire protection zone where a fire exists according to the fire signal, starting a fire-fighting agent bottle group, and spraying the fire-fighting agent to the fire protection zone through a fire-fighting pipeline;

[0099] S13, after a preset delay, judging whether the fire is extinguished according to the fire signal, if not, starting the next fire-fighting agent bottle group to spray the fire-fighting agent to the fire protection area;

[0100] S14. Repeat step S13 until there is no fire signal and the fire is deemed to be extinguished.

[0101] In this embodiment, the fire protection system structure used can refer to Figure 1 When the energy storage system 1 experiences thermal runaway, the fire is detected by the detector inside the cabinet, and the signal is transmitted to the fire control center of the data center, and then to the main control system of the data center. The main control system disconnects the switch Y1 corresponding to the cabinet 1, disconnecting it from the busbar, and the data center uses the remaining cabinets for power supply. If the power supply is insufficient, it takes power from the AC source 2 and closes the switch K and K1.

[0102] At the same time, the fire host transmits the signal to the data center fire execution control system according to the confirmed fire address. After a 30-second delay, the control system closes L1, activates fire bottle 1, and the agent enters the electric cabinet 1 along the pipeline to start the fire extinguishing action. If the thermal runaway of the electric cabinet 1 is not prevented, and smoke is still triggered after 30 minutes, indicating that the thermal runaway is not suppressed, the fire control center will issue an order to let the fire execution control center close L2, activate fire bottle 2, and continue to extinguish the fire in the energy storage system 1. The judgment is repeated in sequence until the fire is extinguished, and the fire-fighting agent is sprayed multiple times to achieve the effect of completely suppressing the re-ignition.

[0103] Similarly, when a fire occurs in cabinet 1 of the data center, the fire is monitored by the detector inside the cabinet and the signal is transmitted to the data center fire control center, and then to the data center main control system. The main control system disconnects the switch X1 corresponding to cabinet 1 to disconnect it from the bus. The computing power of the data center is replaced by closing the switches of other data centers and closing the total switch S1.

[0104] At the same time, the fire host transmits the signal to the data center fire execution control system according to the confirmed fire address. After confirming the 30s delay, the control system closes L1, L2...L z+1 (z is rounded down to an integer), fire bottles 1, 2, 3...z+1 (z is rounded down to an integer), fire agents flow into cabinet 1 along the pipeline, and fire extinguishing actions are carried out. If the fire in cabinet 1 is not stopped and smoke is still triggered after 30 minutes, indicating that the fire is not suppressed, the fire control center will issue an order to let the fire execution control center close L z+1 ····L 2·(z+1) , fire bottles z+1 to 2(z+1) are activated to continue to extinguish the fire in cabinet 1. The judgment is repeated repeatedly until the fire is extinguished, and the fire fighting agent is sprayed multiple times to achieve the effect of completely suppressing the re-ignition.

[0105] Among them, you can refer to Figure 3 The amount of fire-fighting agent in the fire-fighting agent bottle set is set according to the standard fire-fighting agent usage:

[0106] Sa. Obtaining fire protection system parameters and specification data of an energy storage system and a data center, wherein the energy storage system and the data center are connected to the same fire protection system through different fire protection pipelines;

[0107] Sb. Calculate and select the larger value of the fire-fighting agent dosage required by the energy storage system and the data center according to the specification data and the fire-fighting system parameters, and set it as the standard fire-fighting agent usage;

[0108] The specification data include the net volume V and the fire extinguishing design concentration C of a single protection zone;

[0109] The fire protection system parameters include the mass volume fraction S of the fire protection agent at standard atmospheric pressure and minimum ambient temperature;

[0110] The calculation of the fire-fighting agent dosage is specifically as follows:

[0111]

[0112] Wherein, W is the weight of the agent and K is the preset altitude correction factor.

[0113] In this embodiment, refer to Figure 4 The architecture design of the power supply for the data center and energy storage system consists of multiple sets of electrical cabinets, multiple sets of cabinets, multiple sets of fire cylinder groups, AC sources, and diesel generator systems, which are hung on the 750V / 1500V DC bus. The source end is composed of electrical cabinets, AC source 1, AC source 2, AC source 3, and DC source 1, and the load end is composed of the data center. The electrical cabinets are divided into electrical cabinet 1, electrical cabinet 2, electrical cabinet 3, electrical cabinet 4, electrical cabinet 5, and electrical cabinet i (for example), the data center cabinets are divided into cabinet 1, cabinet 2, cabinet 3, cabinet 4, cabinet 5, and cabinet j (for example), and the fire cylinders are divided into fire cylinder group 1, fire cylinder group 2, fire cylinder group 3, and fire cylinder group n.

[0114] In the design of fire fighting agents, reasonable calculations are used to ensure that the fire fighting system's agent dosage meets a larger group and can be flexibly allocated. The fire fighting system's agent dosage calculation formula is shown above.

[0115] For the energy storage system, assuming that the design of each energy storage cabinet is the same, the internal space is the same, that is: V1 = V2 = ... = V i The fire extinguishing design concentration and the mass volume fraction of the agent of each energy storage system are also the same, using the same agent and design, that is: S1 = S2 = ... = S i , C1=C2=…=C i .

[0116] Then W1=W2=…=W i ;

[0117] in:

[0118] W1, W2, W i The weight of fire fighting agents No. 1, No. 2 and No. i;

[0119] V1, V2, V i is the net volume of the protection areas No. 1, No. 2 and No. i;

[0120] S1, S2, S i is the mass volume fraction of agents No. 1, No. 2 and No. i at 101 kPa and the lowest ambient temperature;

[0121] C1, C2, C i Design concentration for fire extinguishing of No. 1, No. 2 and No. i.

[0122] For the data center cabinet system, assuming that the design of each cabinet is the same, the internal space is the same, that is: V'1 = V'2 = ... = V' i ; The fire extinguishing design concentration and mass volume fraction of the agent of each energy storage system are also the same, using the same agent and design, that is: S'1 = S'2 = ... = S' i , C'1=C'2=…=C' i .

[0123] Then W'1=W'2=…=W' i ;

[0124] W'1, W'2, W' i The weight of fire fighting agents No. 1, No. 2 and No. i;

[0125] V'1, V'2, V' i is the net volume of the protection areas No. 1, No. 2 and No. i;

[0126] S'1, S'2, S' i is the mass volume fraction of agents No. 1, No. 2 and No. i at 101 kPa and the lowest ambient temperature;

[0127] C'1, C'2, C' i Design concentration for fire extinguishing of No. 1, No. 2 and No. i.

[0128] In order to unify the fire protection design of the data center and the energy storage system, the selected fire protection agents are unified, S'1 = S1.

[0129] Since the fire extinguishing mechanism of the energy storage system is different from that of the data center, the fire extinguishing design concentration is different. Assume that:

[0130] C'1=x·C1;

[0131] V'1=y·V1;

[0132] but:

[0133]

[0134] Substitute into the above formula:

[0135]

[0136] make:

[0137]

[0138] but:

[0139] W'1=z·W1;

[0140] Assuming z≥1, then W'1≥W1, and the design sets the amount of medicine in fire bottle group 1 to W'1; similarly, the amount of medicine in fire bottle groups 2, 3...n is also W'1.

[0141] Therefore, the amount of fire-fighting agent required by the data center and the energy storage system can be directly calculated, and the larger value can be selected to design the amount of fire-fighting agent for the fire-fighting bottle group. The above z value can also be calculated according to the specification data to determine the larger value of the amount of fire-fighting agent required by the data center and the energy storage system. For specific calculations, refer to the following steps:

[0142] Step Sb comprises the steps of:

[0143] Sb1. Determine the energy storage system and the data center, based on the specification data, whichever requires a larger amount of fire-fighting agent, and obtain standard data;

[0144] Step Sb1 includes the steps of:

[0145] According to the specification data, the judgment parameter z is calculated:

[0146]

[0147]

[0148] Among them, C1 is the fire extinguishing design concentration of the energy storage system, C ’ 1 is the fire extinguishing design concentration of the data center, V1 is the net volume of a single protection zone in the energy storage system, and V'1 is the net volume of a single protection zone in the data center;

[0149] The determination parameter z is determined. If z≥1, it is determined that the amount of fire-fighting agent required by the data center is larger. Otherwise, it is determined that the amount of fire-fighting agent required by the energy storage system is larger.

[0150] Sb2. Calculate the required amount of fire-fighting agent based on the fire-fighting system parameters and the specification data of the standard data party to obtain the standard fire-fighting agent usage.

[0151] Please refer to Figure 1 , Embodiment 2 of the present invention is:

[0153] It includes a control mechanism, which is communicated with each fire-fighting agent bottle group, valve and detector in each protection zone, can control the opening and closing of the fire-fighting agent bottle group and valve, and implements step S1 in the fire control method shown in the above embodiment 1 through the control mechanism.

[0154] In this embodiment, Figure 1 As shown, the data center is provided with cabinets 1 to j, each cabinet is provided with a fire-fighting agent spraying mechanism, and is connected to a fire-fighting bottle group through a fire-fighting pipeline. The fire-fighting pipeline is provided with a valve at the position of each cabinet, namely valves S1 to Sj.

[0155] Similarly, the energy storage system is equipped with i energy storage cabinets, each of which is equipped with a fire-fighting agent spraying mechanism and connected to a fire-fighting bottle group through a fire-fighting pipeline. The fire-fighting pipeline is equipped with a valve at the location of each energy storage cabinet, namely valves K1 to Ki. In addition, the fire-fighting pipeline is designed with a total valve for the data center and the energy storage system, respectively, S total and K total.

[0156] At the same time, each fire cabinet is provided with a detector for detecting fire (such as temperature detection, smoke detection, etc.), and the detector is connected to the control mechanism. In this embodiment, the control mechanism includes a data center main control system, a data center fire control system, and a data center fire execution control system, and the three communicate with each other. At the same time, the control mechanism connects each fire cylinder group (gas cylinder group 1 to gas cylinder group n) and controls the fire cylinder group.

[0157] The amount of fire fighting agent in each fire fighting agent bottle group is determined by the standard fire fighting agent usage calculated by the fire fighting agent amount calculation steps Sa and Sb in the above embodiment 1.

[0158] In summary, the present invention provides a control method and a fire protection system, in which a unified fire protection system provides fire protection support for an energy storage system and a data center.
