In addition, the "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if there is transmission of electrical signals or data between the connected objects.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0036] In an exemplary embodiment, as shown in FIG1 , the present application provides a supervision system for a high-voltage cascade energy storage system, the supervision system comprising: a safety integrated processing platform 2, a power supply device 4, a monitoring device 6, and a spraying device 8; wherein the power supply device 4 is respectively connected to the power grid 300, the safety integrated processing platform 2, the monitoring device 6, and the spraying device 8, the power supply device 4 is used to supply power to the safety integrated processing platform 2, the monitoring device 6, and the spraying device 8, and the monitoring device 6 is also connected to the spraying device 8; the monitoring device 6 is used to collect smoke concentration data, temperature data, carbon monoxide concentration data, and fire extinguishing agent remaining capacity data in the spraying device 8 in the environment where the high-voltage cascade energy storage system is located; the safety integrated processing platform 2 is integrated with the corresponding The central monitoring module 22 and the protection control module 24 are interconnected, and the security integrated processing platform 2 is configured with a communication port. The central monitoring module 22 is connected to the monitoring device 6 through the communication port, and the protection control module 24 is communicatively connected to the sprinkler device 8; the central monitoring module 22 is used to receive and generate a safety alarm signal according to smoke concentration data, temperature data and carbon monoxide concentration data; the protection control module 24 is used to determine the type of the safety alarm signal, and when it is determined that the type of the safety alarm signal is a warning control signal, control the sprinkler device 8 to release the fire extinguishing agent, and after determining that the fire extinguishing agent has been released according to the remaining capacity data of the fire extinguishing agent in the sprinkler device 8, control the power supply device 4 to stop supplying power to the sprinkler device 8.

[0037] Among them, the safety integrated processing platform 2 integrates a central monitoring module 22 and a protection control module 24. The central monitoring module 22 is responsible for receiving various environmental data transmitted from the monitoring device 6, such as smoke concentration, temperature and carbon monoxide concentration, and generating safety alarm signals accordingly. The function of the protection control module 24 is to analyze these alarm signals. If the signal indicates an early warning control signal, it will drive the sprinkler device 8 to work, and control the power supply to the sprinkler device 8 to be cut off after the spraying is completed. The power supply device 4 can refer to an uninterruptible power supply (UPS), which is connected to the power grid 300 and provides power support for the safety integrated processing platform 2, the monitoring device 6 and the sprinkler device 8. In the event of a power outage in the main power grid 300, the power supply device 4 can ensure that the safety integrated processing platform 2, the monitoring device 6 and the sprinkler device 8 can still operate normally, thereby ensuring that the supervision system can maintain basic functions in an emergency. The sprinkler device 8 refers to a fire extinguishing facility. For example, it can be composed of a cylinder filled with fire extinguishing agent and an electrical valve. When the protection control module 24 in the safety integrated processing platform 2 recognizes the early warning control signal, it means that there is a fire at this time, and the sprinkler device 8 will be activated to release the fire extinguishing agent to extinguish the fire. After the spraying is completed, the supervision system will automatically cut off the power supply to the sprinkler device 8 to prevent unnecessary power consumption and possible electrical failures.

[0038] Exemplarily, under the power supply of the power supply device 4, the monitoring device 6 collects the smoke concentration data, temperature data, and carbon monoxide concentration data of the environment of the high-voltage cascade energy storage system in real time, and transmits the collected data to the central monitoring module 22. After receiving the above data, the central monitoring module 22 generates a safety alarm signal according to the numerical values ​​of the smoke concentration data, temperature data, and carbon monoxide concentration data; for example, when a certain data is greater than the corresponding preset threshold, it indicates that there may be a fire safety hazard at this time, based on which, the central monitoring module 22 will generate a safety alarm signal. It should be noted that the generated safety alarm signal can include smoke concentration data, temperature data, carbon monoxide concentration data, and an enable signal for driving the protection control module 24 to work, so that when the protection control module 24 receives the safety alarm signal, the protection control module 24 is enabled to distinguish the safety alarm signal based on the smoke concentration data, temperature data, and carbon monoxide concentration data to determine the type of the safety alarm signal. When the type of the safety alarm signal is determined to be a warning control signal, it indicates that there is a fire in the environment of the high-voltage cascade energy storage system at this time, and then the sprinkler device 8 is controlled to release the fire extinguishing agent. During the process of spraying the fire extinguishing agent, the remaining capacity data of the fire extinguishing agent in the spraying device 8 is collected in real time through the monitoring device 6, and transmitted to the protection control module 24 through the central supervision module 22, so that the protection control module 24 determines whether the fire extinguishing agent has been released according to the remaining capacity data of the fire extinguishing agent in the spraying device 8. After determining that the release is complete, the protection control module 24 will control the power supply device 4 to stop supplying power to the spraying device 8, thereby avoiding damage to electrical equipment such as the power supply device 4 under the influence of the fire extinguishing agent, thereby reducing the risk of secondary accidents that may be caused by electrical failures.

[0039] The supervision system of the above-mentioned high-voltage cascade energy storage system, by embedding the central supervision module in the safety integrated processing platform, enables information sharing between the protection control module in the safety integrated processing platform and the central supervision module. For example, the central supervision module has the function of monitoring information, and based on the built-in overall relationship, the protection control module in the safety integrated processing platform also has the functional attributes of the central supervision module, that is, it can also obtain monitoring information, thereby avoiding the failure and error reporting of related components of the independent central supervision module before being built-in, resulting in the safety integrated processing platform being unable to promptly handle the failure and error reporting of components of the central supervision module due to the communication response time difference. At the same time, the intermediate links are reduced, the potential errors in data transmission are reduced, the probability of safety risks is reduced, the complexity of maintenance and management is reduced, a faster monitoring and response mechanism is achieved, and the efficiency of handling emergencies is improved.

[0040] In an exemplary embodiment, the protection control module 24 is also used to determine, based on the safety alarm signal, that the duration of the smoke concentration data being greater than the smoke concentration safety threshold, the duration of the temperature data being greater than the temperature safety threshold, and the duration of the carbon monoxide concentration data being greater than the carbon monoxide concentration safety threshold are all greater than a preset time, and determine that the type of the safety alarm signal is a warning control signal.

[0041] Exemplarily, based on the smoke concentration data, temperature data and carbon monoxide concentration data transmitted in real time by the central monitoring module 22, the duration of the smoke concentration data being greater than the smoke concentration safety threshold, the duration of the temperature data being greater than the temperature safety threshold, and the duration of the carbon monoxide concentration data being greater than the carbon monoxide concentration safety threshold are calculated simultaneously from the same time node. When the durations of all three are greater than the preset time, the type of the safety alarm signal is determined to be a warning control signal.

[0042] In this embodiment, by comprehensively considering the duration that the three parameters of smoke concentration, temperature and carbon monoxide concentration exceed their respective safety thresholds, and triggering the early warning control signal when these conditions simultaneously meet the preset time requirements, it not only improves the accuracy of the fire warning and avoids the possibility of false alarm of a single parameter, but also ensures that emergency response measures can be initiated in a timely and effective manner when a real fire hazard occurs, thereby enhancing the safety and reliability of the high-voltage cascade energy storage system.

[0043] In an exemplary embodiment, the central monitoring module 22 is also used to generate a safety alarm signal and cut off other electrical equipment 500 connected to the power supply device 4 when the duration of the smoke concentration data being greater than the smoke concentration safety threshold is greater than a preset time or the duration of the temperature data being greater than the temperature safety threshold is greater than a preset time; wherein the other electrical equipment 500 includes: non-emergency lighting equipment, air conditioning and heating systems.

[0044] Exemplarily, the central monitoring module 22 calculates the duration of the smoke concentration data being greater than the smoke concentration safety threshold, or the duration of the temperature data being greater than the temperature safety threshold, based on the smoke concentration data and temperature data transmitted in real time by the monitoring device 6. When the duration of one of the data being greater than the corresponding safety threshold is greater than the preset time, it indicates that the monitoring system of the high-voltage cascade energy storage system has a fire safety hazard, and then generates a safety alarm signal to achieve subsequent supervision. At the same time, as shown in FIG1 , if the power supply device 4 is also connected to other electrical equipment 500 such as non-emergency lighting equipment, air conditioning and heating systems, these other electrical equipment 500 are cut off from the power supply circuit to reduce potential fire risks and avoid equipment damage. Furthermore, in addition to this, in the case of fire safety hazards, electricity can be mainly supplied to the safety integrated processing platform 2, the monitoring device 6 and the sprinkler device 8 to provide power guarantee for safety supervision.

[0045] In this embodiment, the smoke concentration and temperature data are monitored in real time through the central monitoring module, and when any data exceeds the safety threshold for a preset time, a safety alarm signal is generated and the power supply of non-critical electrical equipment, such as non-emergency lighting equipment, air conditioning and heating systems, is immediately cut off. This not only helps to reduce potential fire risk points and prevent the spread of fire, but also ensures the power supply of key safety equipment such as safety integrated processing platforms, monitoring devices and sprinkler devices, thereby improving the overall safety performance and emergency response capabilities of the high-voltage cascade energy storage system.

[0046] In an exemplary embodiment, the protection control module 24 is also used to determine that the type of the safety alarm signal is a fire alarm signal and switch the power supply device 4 to an emergency response power supply mode when it is determined based on the safety alarm signal that the duration of the smoke concentration data is greater than the smoke concentration safety threshold and the duration of the temperature data is greater than the temperature safety threshold are both greater than a preset time.

[0047] Exemplarily, based on the smoke density data and temperature data transmitted in real time by the central monitoring module 22, the duration of the smoke density data being greater than the smoke density safety threshold and the duration of the temperature data being greater than the temperature safety threshold are calculated from the same time node. When the duration of both is greater than the preset time, the type of the safety alarm signal is determined to be a fire alarm signal. When it is determined to be a fire alarm signal, the central monitoring module 22 will set the power supply device 4 to the emergency response power supply mode, which specifically means that on the one hand, the power supply device 4 is prepared to supply power to the safety integrated processing platform 2, the monitoring device 6 and the sprinkler device 8 based on the battery cells carried by the power supply device 4 itself when the power grid 300 fails as the main power supply, so as to ensure the normal operation of the monitoring system and related equipment (such as alarms, fire extinguishing systems, emergency lighting, etc.), and on the other hand, the power supply device 4 is kept in a standby state to ensure that the necessary power support can be quickly provided in the event of a fire alarm.

[0048] In this embodiment, by continuously monitoring the smoke concentration and temperature data and triggering a fire alarm signal when both exceed the safety threshold for a preset time, the fire risk can be identified in a timely and accurate manner, and the power supply mode can be quickly switched to the emergency response state to ensure that the power supply of key safety equipment is not affected, thereby effectively ensuring the fire safety of the high-voltage cascade energy storage system and improving the ability to respond to emergencies.

[0049] In an exemplary embodiment, as shown in FIG2 , the power supply device 4 includes: an AC / DC rectifier 42, a DC converter 44 and a replacement battery cell 46; wherein the AC / DC rectifier 42 is connected to the power grid 300 and the DC converter 44, respectively, and the DC converter 44 is also connected to the replacement battery cell 46 and the safety integrated processing platform 2; the central monitoring module 22 is used to activate the replacement battery cell 46 when it is determined that the type of the safety alarm signal is a fire alarm signal; the protection control module 24 is used to cut off the power supply of the replacement battery cell 46 after the spray device 8 is released.

[0050] The power supply device 4 includes an AC / DC rectifier 42, a DC converter 44 and a replacement battery 46. The power supply device 4 includes a UPS power supply mode. Specifically, under normal working conditions, the AC power output by the power grid 300 is converted into DC power by the AC / DC rectifier 42, and then the DC converter 44 performs voltage regulation and outputs it to the safety integrated processing platform 2, the monitoring device 6, the sprinkler device 8 and other equipment, and charges the replacement battery 46 at the same time; when the power grid 300 is disconnected, the replacement battery 46 is used as a power supply device, and is output to the safety integrated processing platform 2, the monitoring device 6, the sprinkler device 8 and other equipment after voltage regulation by the DC converter. When the central monitoring module 22 determines that the type of the safety alarm signal is a fire alarm signal, the power supply device 4 is switched to the emergency response power supply mode, that is, by activating the replacement battery 46, so that the replacement battery 46 can respond as a power supply device at any time when the power grid 300 is disconnected or a fire occurs, and is output to the safety integrated processing platform 2, the monitoring device 6, the sprinkler device 8 and other equipment after voltage regulation by the DC converter. Among them, as shown in FIG2 , when the power supply device 4 is also connected to other electrical equipment 500, the other electrical equipment 500 is connected between the AC-DC rectifier 42 and the DC converter 44, so that when there is a fire safety hazard in the environment where the high-voltage cascade energy storage system is located, other electrical equipment 500 can be efficiently and conveniently disconnected without powering off, thereby ensuring the safety of the energy storage system. When it is confirmed that the type of the safety alarm signal is a warning control signal, in order to ensure that the sprinkler 8 can release the fire extinguishing agent normally, the power supply of the sprinkler 8 will be supplied by the replacement battery 46. Therefore, after the sprinkler 8 is released, the protection control module 24 cuts off the power supply of the replacement battery 46, so that the sprinkler 8 is powered off after the spraying is completed, so as to avoid damage to the replacement battery 46 under the influence of the fire extinguishing agent, thereby reducing the risk of secondary accidents that may be caused by electrical failures.

[0051] In this embodiment, by setting up a power supply device including an AC-DC rectifier, a DC converter and a replacement battery cell, it is possible to use the power grid for power supply under normal working conditions, and seamlessly switch to the replacement battery cell for power supply when the grid fails or a fire occurs, ensuring the continuous operation of key components such as the safety integrated processing platform, the monitoring device and the sprinkler. In addition, when a fire alarm signal is detected, the power supply of non-critical equipment can be cut off first, while ensuring the effective operation of the sprinkler device, and the power can be cut off in time after the sprinkler is finished, thereby effectively improving the safety and emergency response efficiency of the high-voltage cascade energy storage system and reducing the risk of secondary accidents.

[0052] In an exemplary embodiment, as shown in FIG2 , the monitoring device 6 includes: a smoke concentration monitoring unit 62, a temperature monitoring unit 64, a carbon monoxide concentration monitoring unit 66 and a spray status monitoring unit 68; wherein the smoke concentration monitoring unit 62, the temperature monitoring unit 64, the carbon monoxide concentration monitoring unit 66 and the spray status monitoring unit 68 are all connected to the central monitoring module 22 via a communication terminal, and the spray status monitoring unit 68 is also connected to the spray device 8; the smoke concentration monitoring unit 62 is used to collect smoke concentration data, the temperature monitoring unit 64 is used to collect temperature data, the carbon monoxide concentration monitoring unit 66 is used to collect carbon monoxide concentration data, and the spray status monitoring unit 68 is used to collect the remaining capacity data of the fire extinguishing agent in the spray device 8.

[0053] In this embodiment, by subdividing the monitoring device into a smoke concentration monitoring unit, a temperature monitoring unit, a carbon monoxide monitoring unit and a sprinkler status monitoring unit, it is possible to more accurately monitor a variety of key safety parameters in the high-voltage cascade energy storage system environment independently and transmit them to the central supervision module in real time through the communication terminal, so that the supervision system can respond to and deal with potential fire hazards in a timely manner, and at the same time comprehensively manage the status of the sprinkler device, thereby significantly improving the overall safety and reliability of the system.

[0054] In an exemplary embodiment, as shown in FIG. 2 , the safety integrated processing platform 2 is also used to determine that the fire extinguishing agent has been released when the remaining capacity data of the fire extinguishing agent in the sprinkler device 8 is less than a preset capacity threshold.

[0055] Exemplarily, the sprinkler device 8 may be composed of a steel cylinder filled with a fire extinguishing agent and a related electrical switch. The central monitoring module 22 may receive data on the remaining capacity of the fire extinguishing agent in the steel cylinder transmitted by the sprinkler status monitoring unit 68. If the remaining capacity of the fire extinguishing agent in the steel cylinder drops to 0, it indicates that the steel cylinder has been sprayed, i.e., it is determined that the fire extinguishing agent has been released.

[0056] In this embodiment, by real-time monitoring of the remaining capacity of the fire extinguishing agent in the sprinkler and confirming that the fire extinguishing agent has been released when the capacity is lower than a preset threshold, it is possible to ensure that the state of the fire extinguishing agent is accurately grasped during the fire extinguishing process, thereby effectively preventing the occurrence of incomplete fire extinguishing or delay in subsequent remedial measures due to failure to notify in time due to exhaustion of the fire extinguishing agent, thereby improving the safety protection level of the high-voltage cascade energy storage system.

[0057] In an exemplary embodiment, as shown in FIG3 , the present application further provides a supervision method for a high-voltage cascade energy storage system, which is applied to the supervision system for the high-voltage cascade energy storage system in the above embodiment, and the supervision method includes:

[0058] Step 1: The central monitoring module receives and generates a safety alarm signal based on smoke concentration data, temperature data and carbon monoxide concentration data;

[0059] Step 2: The protection control module determines the type of the safety alarm signal;

[0060] Step three, when the protection control module determines that the type of the safety alarm signal is a warning control signal, the protection control module controls the sprinkler device to release the fire extinguishing agent, and controls the power supply device to stop supplying power to the sprinkler device after the release is completed.
