[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments of the present application.

[0054] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to the process, method, product, or device.

[0055] Fig. 1 is a structural schematic diagram of an energy storage cabinet fire extinguishing system according to an embodiment of the present application. As shown in Fig. 1, the energy storage cabinet fire extinguishing system includes a self-powered module 10, a fire detection module 20, and a fire prevention strategy generation module 30.

[0056] The self-powered module 10 is used to supply power to the energy storage cabinet fire extinguishing system by using the energy storage device battery inside the self-powered module when the external power supply is disconnected, so as to ensure that the fire extinguishing system can still work normally even when the external power supply is interrupted, and to avoid the fire extinguishing system from being disabled due to the interruption of the external power supply in an emergency fire situation, thereby greatly improving the reliability of the fire extinguishing system.

[0057] The fire detection module 20 is used to acquire the running state information of the energy storage cabinet in real time and monitor the running state information.

[0058] The operation state information is environment information and picture information of the energy storage cabinet during operation. The environment information can include smoke concentration, temperature, and gas information, and the picture information includes abnormal pictures, such as whether there is an open flame, the size of the fire, and the like. Specifically, by acquiring the environment information and picture information of the energy storage cabinet during operation in real time through various sensors, and monitoring the operation state information, the occurrence of a fire can be detected in a timely and accurate manner. For example, a smoke sensor is used to collect the smoke concentration value of the energy storage cabinet, a temperature sensor is used to collect the temperature value of the energy storage cabinet, a gas sensor is used to detect whether there is an abnormal odor during operation of the energy storage cabinet, and a picture monitoring device is used to detect whether there is an abnormal picture during operation of the energy storage cabinet.

[0059] The fire prevention strategy generation module 30 is configured to generate a fire prevention strategy based on the real-time operation state information of the energy storage cabinet and the pre-stored historical fire data, so that the staff can take proactive protective measures according to the fire prevention strategy.

[0060] The historical fire data can be obtained by collecting and sorting related data stored when a fire occurs in the same type of energy storage cabinet on the market, including the time, location, cause of fire, fire type, and fire extinguishing method. Specifically, when a fire does not occur, the fire prevention strategy generation module predicts whether the current operation stage of the energy storage cabinet is in a time period when a fire is likely to occur based on the real-time operation state information of the energy storage cabinet and the pre-stored historical fire data. If so, a fire prevention strategy is automatically generated based on a preset algorithm according to the time, location, cause of fire, fire type, and fire extinguishing method, including the type of fire extinguishing agent, the amount of fire extinguishing agent, and the fire extinguishing method, so that the staff can take proactive protective measures according to the fire prevention strategy. When a fire occurs, the fire prevention strategy generation module uses a risk assessment function constructed by a machine learning algorithm to evaluate the fire risk level based on the real-time operation state information of the energy storage cabinet and the pre-stored historical fire data. A fire extinguishing strategy is generated according to the evaluation result of the current fire risk level and the operation state information of the current energy storage cabinet, including the type of fire extinguishing agent, the amount of fire extinguishing agent, and the fire extinguishing method, to ensure effective fire extinguishing in the shortest time, and continuously monitor the real-time operation state information of the energy storage cabinet, update the fire risk assessment result in real time, and adjust the type of fire extinguishing agent and the amount of fire extinguishing agent based on the real-time evaluation result to improve the fire extinguishing efficiency.

[0061] The technical scheme provided by the embodiments of the present application is that when the external power supply is disconnected, the battery in the self-powered module is used to supply power for the energy storage cabinet fire-fighting system, so that the fire-fighting system can still work normally even when the external power supply is interrupted, and the fire-fighting system will not fail due to interruption of the external power supply in the case of an emergency fire, thereby greatly improving the reliability of the fire-fighting system. The running state information of the energy storage cabinet is acquired in real time by the fire detection module, and the running state information is monitored, so that abnormalities can be detected in the early stage of a fire, and early warning can be provided to prevent the fire from further expanding. The fire prevention strategy generation module generates a fire prevention strategy based on the real-time running state information of the energy storage cabinet and the historical fire data stored in advance, so that the staff can take proactive protective measures according to the fire prevention strategy, and thus the development of the fire can be timely and effectively suppressed.

[0062] Continuing to refer to FIG. 1, optionally, the self-powered module 10 includes an energy storage device battery 11, a charging management unit 12, and a power conversion unit 13.

The energy storage device battery refers to a device that converts electrical energy into chemical energy, physical energy or kinetic energy, and stores it for release as electrical energy when needed. Common energy storage device batteries include lead-acid batteries, lithium-ion batteries, sodium-sulfur batteries, zinc-air batteries, etc. Specifically, the charging management unit charges the energy storage device battery to ensure that the energy storage device battery always stores power, and when the external power supply is disconnected, the energy storage device battery 11 is used to supply power for the energy storage cabinet fire-fighting system.

[0064] Continuing to refer to FIG. 1, optionally, the power conversion unit 13 includes a power state monitoring subunit 131, an intelligent judgment subunit 132, and an alarm subunit 133.

[0065] The power state monitoring subunit 131 is configured to monitor the state of the external power supply and the power of the energy storage device battery 11 in real time. The external power supply refers to the power supply required for the normal operation of the energy storage cabinet, and the state of the external power supply refers to a normal power supply state or a power-off state. Specifically, the power state monitoring subunit monitors whether the external power supply is in a normal power supply state and the power of the energy storage device battery 11 in real time.

[0066] The intelligent judgment subunit 132 is configured to judge the state of the external power supply and the power of the energy storage device battery 11. Specifically, the intelligent judgment subunit 132 judges whether the state of the external power supply is in a normal power supply state and whether the power of the energy storage device battery 11 is less than a preset power threshold. When the external power supply is powered off, the energy storage device battery 11 is switched to supply power to the energy storage cabinet fire extinguishing system. When the power of the energy storage device battery 11 is less than the preset power threshold, the external power supply is restored. When the power of the energy storage device battery is greater than or equal to the preset power threshold, the energy storage device battery is continuously used to supply power.

[0067] The alarm subunit 133 is configured to issue an alarm and safely shut down when switching fails or restoration fails.

[0068] Specifically, when the external power supply is powered off and cannot be switched to the energy storage device battery 11 to supply power to the energy storage cabinet fire extinguishing system, or when the power of the energy storage device battery 11 is less than the preset power threshold and the external power supply cannot be restored, the alarm subunit 133 issues an alarm and safely shuts down. A backup power supply can also be enabled to supply power. If the backup power supply cannot be enabled, the system safely shuts down.

[0069] FIG. 2 is a system flowchart of the self-power supply module in the energy storage cabinet fire extinguishing system according to an embodiment of the present application. Referring to FIG. 2, at the beginning, the energy storage cabinet fire extinguishing system is normally supplied with power by the external power supply 201, which can also charge the energy storage device battery 202. The external power supply 201 is judged to be disconnected at 203, and the power of the energy storage device battery 202 is judged to be less than a preset power threshold at 204. When the external power supply 201 is disconnected, the energy storage device battery 202 is switched to supply power to the energy storage cabinet fire extinguishing system. When the power of the energy storage device battery 202 is less than the preset power threshold, the external power supply 201 is restored. When the external power supply is disconnected and cannot be switched to the energy storage device battery 202 to supply power to the energy storage cabinet fire extinguishing system, or when the power of the energy storage device battery 202 is less than the preset power threshold and the external power supply 201 cannot be restored, an alarm is issued at 205 and a backup power supply or safe shutdown is started at 206. If the backup power supply cannot be enabled, the system safely shuts down.

[0070] Further, the specific relationship between the external power supply and the charging of the energy storage device battery should satisfy the following formula:

[0071] The formula indicates that the remaining power of the external power supply supply minus the load demand is used to charge the energy storage device battery. Wherein, P ext (t) is the external power supply power (a function of time t); P load (t) is the load power demand (a function of time t); I batt(t) is the battery power of the energy storage device (a function of time t) ; I batt (t) is the battery voltage of the energy storage device (a function of time t).

[0072] The monitoring and conversion judgment of the battery power of the energy storage device should satisfy the following formula:

[0073] Wherein, E batt (t) is the battery power of the energy storage device (a function of time t) ; I batt (t) is the battery power of the energy storage device (a function of time t) ; I batt (t) is the battery voltage of the energy storage device (a function of time t). The formula indicates that when the battery power E batt (t) of the energy storage device is less than the preset power threshold, the above formula is used to charge the battery of the energy storage device with the remaining power of the external power supply minus the load demand; when the external power P ext (t) = 0, the battery of the energy storage device starts to supply power.

[0074] The different power states of the system at time t should satisfy the following formula:

[0075] According to different power sources, the value range of the formula indicates the different power states of the system under the external power supply, the battery of the energy storage device, the standby power supply system and the safe shutdown mode. Wherein, P ext (t) is the external power, P load (t) is the load power demand, E batt (t) is the battery power of the energy storage device, E thresh is the preset threshold of the battery power of the energy storage device, P backup (t) is the standby power supply system power, P safe (t) is the safe shutdown power demand.
