Description

[0002] With the rapid development of renewable energy, industrial and commercial energy storage cabinets, as important energy storage equipment, play an increasingly important role in the power system. These energy storage cabinets are usually deployed in the wild environment to store and regulate electricity to cope with grid fluctuations and provide backup power. However, the wild environment is complex and changeable. Natural factors such as temperature, humidity, wind speed, and external interference such as dust and animals may affect the internal environment of the energy storage cabinet, thus posing a challenge to the stable operation of the fire protection system.

[0003] Existing industrial and commercial energy storage cabinet fire protection systems mainly rely on fire monitoring equipment such as smoke detectors, temperature detectors or composite detectors to monitor the safety status inside the energy storage cabinet in real time. These detectors determine whether a fire has occurred by monitoring parameters such as smoke concentration and temperature. When the monitoring value of a detector reaches the preset threshold, the control system will automatically trigger the fire extinguishing device to extinguish the fire. However, due to the complexity and uncertainty of the field environment, the detector is easily affected by external interference or its own failure, resulting in false alarms of fire. False alarms trigger unnecessary fire extinguishing operations, which will waste precious fire extinguishing resources, damage the equipment in the energy storage cabinet, and even cause greater safety hazards and economic losses.

[0004] Therefore, how to improve the accuracy and reliability of the energy storage cabinet fire protection system in harsh outdoor environments and reduce the occurrence of false alarms has become a problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] like Figure 1 As shown, a reliable monitoring industrial and commercial energy storage cabinet fire protection system described in one embodiment of the present invention includes a control module 1, a monitoring module 2 and an execution module 3 which are communicatively connected to the control module 1, the monitoring module 2 includes a temperature sensor 201 and a smoke sensor 202, and a plurality of the temperature sensor 201 and the smoke sensor 202 are provided. When at least two of the temperature sensor 201 and the smoke sensor 202 reach a monitoring threshold, the control module 1 controls the execution module 3 to extinguish the fire.

[0038] When the system is working, multiple temperature sensors 201 and smoke sensors 202 are distributed in key positions of the energy storage cabinet 7. The accuracy of the sensors is selected according to the needs, and the temperature changes and smoke concentrations in the cabinet are continuously and uninterruptedly monitored. When the monitoring value of any sensor reaches the preset safety threshold, the system will immediately enter the early warning state, and the fire extinguishing operation will not be triggered at this time. When at least two sensors (such as a temperature sensor 201 and a smoke sensor 202, or two temperature sensors 201, or two smoke sensors 202) detect an abnormality at the same time, and both reach or exceed their respective thresholds, the system confirms that a fire has occurred, and then sends a fire extinguishing instruction to the execution module 3 through the control module 1, starts the fire extinguishing device 301, and performs fire extinguishing treatment inside the energy storage cabinet 7. After the fire extinguishing operation is completed, the control module 1 continues to monitor the internal state of the energy storage cabinet 7 to ensure that the fire is effectively controlled. In addition, the system records the relevant data of this event, including the time of fire occurrence, fire extinguishing response time, fire extinguishing effect, etc., to provide a basis for subsequent analysis and improvement.

[0039] In this embodiment, through multiple sensor monitoring and composite judgment logic, multiple sensors perform environmental monitoring on multiple locations of the energy storage cabinet 7, which greatly improves the accuracy and reliability of fire identification, effectively reduces the false alarm rate caused by single sensor failure or external interference, reduces unnecessary fire extinguishing operations and waste of resources, and avoids damage to the internal equipment of the energy storage cabinet 7 caused by misoperation. Secondly, after confirming the fire, the system can respond quickly and immediately start the fire extinguishing device 301. By accurately controlling the release of the fire extinguishing agent, the fire source inside the energy storage cabinet 7 can be quickly and effectively extinguished, which helps to control the fire within the minimum range at the early stage of the fire and maximize the protection of the safety of the energy storage cabinet 7 and its surrounding facilities. Finally, the system also has data recording and analysis functions, which can record the whole process data of fire warning, confirmation and fire extinguishing operations, provide users with operation feedback and reference basis, help users understand the actual operation status and potential risk points of the energy storage cabinet 7, and provide support for the subsequent optimization of safety management strategies.

[0040] The control module 1 (BMS) includes a master control unit (BAU), a main control unit (BCU) and a slave control unit (BMU), and the battery pack is connected to the AC unit through a high-voltage box (PDU).

[0041] like Figure 1 As shown, in a preferred embodiment, the control module 1 is communicatively connected to the alarm module 4. When the monitoring module 2 reaches a threshold, the control module 1 controls the alarm module 4 to sound an alarm.

[0042] When the temperature sensor 201 or the smoke sensor 202 in the monitoring module 2 reaches its preset threshold value, the control module 1 receives the signal. At this time, even if the composite conditions for triggering the fire extinguishing operation are not met, the control module 1 immediately activates the alarm module 4. The alarm module 4 then emits a clear and loud alarm sound accompanied by flashing lights, or sends a remote alarm signal to a preset receiving end, such as a monitoring center, a manager's mobile phone, etc., to notify relevant personnel to pay attention to the possible fire risk of the energy storage cabinet 7.

[0043] In this embodiment, by setting the alarm module 4, an alarm can be issued at the early stage of a fire, which effectively improves the timely detection rate of a fire, prevents the spread of fire, and reduces property losses and casualties. Secondly, the issuance of an alarm signal can quickly attract the attention of surrounding personnel and management personnel, and buy time for subsequent emergency response and fire extinguishing operations. In addition, the function of the remote alarm signal also ensures that fire information can be received and processed in a timely manner even in a field environment where there is no person on duty, thereby improving the intelligence and automation level of the entire fire protection system.

[0044] like Figure 1 , Figure 4 and Figure 5As shown, in a preferred embodiment, the execution module 3 includes a fire extinguishing device 301 .

[0045] There are various types of fire extinguishing devices 301 to meet different scenarios and needs. They include the following types:

[0046] Perfluorohexanone fire extinguishing device, perfluorohexanone has the advantages of zero ozone depletion potential (ODP), low global warming potential (GWP), high electrical insulation, non-toxicity, and non-corrosiveness. It can quickly extinguish the fire source in a short time and effectively prevent the spread of the fire without causing secondary damage to the equipment. In the energy storage cabinet 7, the perfluorohexanone fire extinguishing device can quickly suppress the thermal runaway of the battery through precise spraying, ensuring the safe and stable operation of the energy storage facility.

[0047] Nitrogen fire extinguishing devices mainly release a large amount of nitrogen in a closed space to reduce the oxygen concentration in the space to below the safe range, thereby achieving the purpose of extinguishing fires. Nitrogen is clean and non-toxic, and can ensure the fire extinguishing effect while preventing secondary damage to the battery. When used, nitrogen fire extinguishing devices are used for fire prevention and control of large-scale centralized energy storage facilities.

[0048] Aerosol fire extinguishers use aerosol fire extinguishing agents composed of solid particles, gaseous media and a small amount of liquid droplets to extinguish fires. Aerosol fire extinguishers are easy to install and take up little space. They can generate a large amount of inert gas in a short period of time, reduce oxygen concentration, and produce an endothermic effect to achieve the purpose of rapid fire extinguishing. Aerosol fire extinguishers are suitable for fire prevention and control in the space inside the energy storage cabinet 7, and can quickly control the fire and prevent the fire from spreading.

[0049] The above-mentioned fire extinguishing devices 301 have their own characteristics and are suitable for different types of energy storage cabinets 7 and fire scenes. When selecting and applying, they are selected and reasonably deployed according to the specific conditions of the energy storage cabinet 7 and fire safety requirements.

[0050] Preferably, the fire extinguishing device 301 is an aerosol fire extinguisher. The aerosol fire extinguisher is small in size, light in weight, easy to install and deploy, and is suitable for energy storage cabinets 7 of various specifications. The number and location of the aerosol fire extinguisher can be flexibly adjusted as needed. In addition, the aerosol fire extinguisher is non-toxic and harmless, safe and reliable. During the fire extinguishing process, it will not cause harm to the human body, and also prevents secondary damage to the equipment inside the energy storage cabinet 7.

[0051] like Figure 5 As shown, in a preferred embodiment, the fire extinguishing device 301 is connected to the cooling air duct 702 in the energy storage cabinet 7 .

[0052] In the fire protection system of the energy storage cabinet 7, when the fire extinguishing device 301 is triggered, the aerosol fire extinguisher is quickly activated and releases the fire extinguishing medium. The fire extinguishing medium enters the cooling air duct 702 in the energy storage cabinet 7 through the pipeline. The cooling air duct 702 is an important channel for heat exchange inside the energy storage cabinet 7 and is distributed between the battery modules, ensuring that the fire extinguishing medium can be widely and evenly distributed to every corner of the energy storage cabinet 7. As the fire extinguishing medium flows, it quickly covers and penetrates the fire source and high temperature area, effectively suppressing the spread of the fire, and reducing the temperature of the battery module and the surrounding environment, thereby preventing the fire from further deteriorating.

[0053] In this embodiment, by connecting the fire extinguishing device 301 with the cooling air duct 702 in the energy storage cabinet 7, the fire extinguishing efficiency and coverage of the fire protection system are significantly enhanced. First, through the guidance of the cooling air duct 702, the fire extinguishing medium can reach the fire source and high-temperature area more accurately, achieve rapid fire extinguishing and cooling, and effectively curb the spread of the fire. Secondly, the flow of the fire extinguishing medium in the air duct promotes the rapid dissipation of heat inside the energy storage cabinet 7, helps to reduce the overall temperature, and prevents the chain reaction caused by overheating of the battery module. In addition, the original cooling system structure of the energy storage cabinet 7 is fully utilized, and there is no need to add a complex fire extinguishing pipeline layout, which reduces the cost and complexity of system transformation.

[0054] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the execution module 3 includes a thyristor 302, and the thyristor 302 is arranged on the line between the battery pack 701 and the AC converter (PCS), or on the line between the battery pack 701 and the powered device.

[0055] In the power transmission and distribution system, when the execution module 3 receives the control signal, the thyristor 302 controlled by it generates a corresponding action. The thyristor 302 on the line between the battery pack 701 and the AC converter controls the on and off of the current according to the control signal, thereby controlling the input power or output power of the battery pack 701. Similarly, the thyristor 302 located on the line between the battery pack 701 and the powered device is used to adjust the process of the battery pack 701 supplying power to the powered device to ensure the stable output of current and voltage. In the event of a fire or the need to disconnect the power supply urgently, the thyristor 302 can quickly cut off the circuit to prevent the current from continuing to flow and protect the circuit and equipment from damage.

[0056] In this embodiment, by setting the thyristor 302, rapid control of the current can be achieved, thereby improving the efficiency and stability of power transmission and distribution. During the power conversion process between the battery pack 701 and the AC or the powered device, the thyristor 302 can adjust the current parameters according to actual needs to ensure efficient use of energy and normal operation of the equipment. Secondly, the thyristor 302 has good overload protection and short-circuit protection functions, and can quickly cut off the power supply when an abnormality occurs in the circuit, effectively preventing equipment damage and fire and other safety accidents. In addition, the thyristor 302 also has the characteristics of fast response speed, high control accuracy, and good reliability. It can adapt to the complex and changeable power transmission and distribution environment and improve the overall performance and safety of the system.

[0057] In a preferred embodiment, the temperature sensor 201 includes a first temperature sensor and a second temperature sensor, the first temperature sensor is arranged in the energy storage cabinet 7 , and the second temperature sensor is arranged in the battery pack 701 .

[0058] During operation, the first temperature sensor is located inside the energy storage cabinet 7, and continuously monitors and records the ambient temperature inside the energy storage cabinet 7. The monitored temperature data is useful for evaluating the overall heat dissipation performance of the energy storage cabinet 7 and preventing overheating. At the same time, the second temperature sensor is arranged inside the battery pack 701, and is set on the electrode of the battery cell to monitor the internal temperature of the battery cell in the battery pack 701 in real time during operation. Since the battery generates heat due to chemical reactions during operation, accurate monitoring of the temperature changes of the battery cell is used to ensure battery safety and optimize the charging and discharging strategy.

[0059] In this embodiment, by adopting a dual temperature sensor 201 layout (the first temperature sensor is in the energy storage cabinet 7, and the second temperature sensor is in the battery pack 701), the overall safety and performance stability of the energy storage system are significantly improved. Specifically, by real-time monitoring of the temperature inside the energy storage cabinet 7 and the battery pack 701, potential overheating risks can be discovered and warned in a timely manner, effectively preventing safety accidents such as fire or battery damage caused by excessive temperature, and allowing the control module 1 to respond quickly and accurately. In addition, accurate temperature data also provides accurate data for optimizing the thermal management strategy of the energy storage system, allowing the system to automatically adjust the heat dissipation mode under different working conditions to ensure that the battery operates within the optimal temperature range, thereby improving the energy conversion efficiency of the battery and extending its service life.

[0060] In a preferred embodiment, the smoke sensors 202 are arranged at intervals in the energy storage cabinet 7 , and at least one smoke sensor 202 is arranged on the top of the energy storage cabinet 7 .

[0061] When the energy storage cabinet 7 is in operation, the smoke sensor 202 is an important safety monitoring device that is in continuous operation and continuously monitors the gas conditions in the energy storage cabinet 7. Multiple smoke sensors 202 arranged at intervals form a multiple monitoring network to ensure effective coverage of the entire energy storage cabinet 7 space. When combustion or smoke occurs in the energy storage cabinet 7, the smoke sensor 202 can respond quickly and detect smoke particles or specific gases produced by combustion through built-in sensitive elements. Subsequently, the smoke sensor 202 will immediately convert the detected smoke signal into an electrical signal and send it to the control module 1, triggering the alarm mechanism.

[0062] The smoke sensor 202 is arranged at intervals in the energy storage cabinet 7, which enhances the fire warning capability of the energy storage system, improves the sensitivity and accuracy of smoke detection, and realizes all-round monitoring of the internal environment of the energy storage cabinet 7 through multiple monitoring points, effectively reducing the missed alarm rate and false alarm rate of fire. When a fire occurs, the smoke sensor 202 can respond quickly, so that the control module 1 quickly issues an alarm, which buys time for personnel evacuation, fire fighting and reducing property losses, and improves the overall safety and reliability of the energy storage system.

[0063] like Figure 1 As shown, in a preferred embodiment, the control module 1 includes a communication module 5, and the communication module 5 includes a local communication unit and a remote communication unit. The local communication unit is used to detect the data of the monitoring module 2 and control the operation of the execution module 3, and the remote communication unit is used to transmit the local status to the adjacent energy storage cabinet 7 and to communicate with the host computer 6.

[0064] The remote communication unit includes wired communication devices and wireless communication devices.

[0065] When working, the local communication unit establishes a connection with the monitoring module 2 via CAN or RS485, and receives data from monitoring devices such as the temperature sensor 201 and the smoke sensor 202 in real time. The control module 1 parses and processes the data to evaluate the current state of the energy storage cabinet 7, such as whether the temperature is too high, whether smoke is generated, etc. Based on these evaluation results, the local communication unit will send control instructions to the execution module 3, such as starting the fire extinguishing device 301, adjusting the thyristor 302 to control the current, etc., to ensure the safe and stable operation of the energy storage cabinet 7.

[0066] At the same time, the remote communication unit is also working continuously. The wired communication device is connected to the adjacent energy storage cabinet 7 through a physical cable to realize the mutual transmission of status information. The communication is stable and reliable, and is suitable for scenes with high requirements for communication quality. That is, the adjacent energy storage cabinet 7 can record the status of the energy storage cabinet 7. When an alarm or fire occurs, the adjacent energy storage cabinet 7 will send an alarm to the host computer 6 at the same time to avoid damage to the communication module 5 of the energy storage cabinet 7 and unable to communicate with the host computer 6 normally, and can provide early warning. In addition, the fire extinguishing devices 301 between the energy storage cabinets 7 that are close to each other are interconnected, that is, the adjacent energy storage cabinets 7 can be assisted in fire extinguishing. The wireless communication device uses wireless signals (such as Wi-Fi, Zigbee, LoRa, etc.) to connect to a wider network, can maintain real-time communication with the host computer 6 (such as a central monitoring system), upload detailed operating data of the energy storage cabinet 7, and receive control instructions and scheduling information from the host computer 6.

[0067] In this embodiment, by setting up a local communication unit and a remote communication unit, it is convenient for the energy storage cabinet 7 to realize safety monitoring and intelligent management. The local communication unit ensures the real-time acquisition of monitoring data and the instant transmission of execution instructions, effectively improving the autonomous control ability of the energy storage cabinet 7. The addition of the remote communication unit further broadens the information exchange channel of the energy storage cabinet 7, realizes the connection with the adjacent energy storage cabinet 7 and the host computer 6, enhances the overall collaborative working ability of the energy storage system, and also facilitates the management personnel to remotely monitor and centrally manage each energy storage cabinet 7 through the host computer 6, greatly improving the work efficiency and response speed. In addition, the remote communication unit includes both wired communication devices and wireless communication devices, and redundant communication improves the reliability and stability of the communication system. When wired communication is blocked or fails, wireless communication can quickly take over the communication task to ensure the continuous transmission of data and the timely issuance of instructions. Vice versa, this mutual backup communication mode effectively reduces the risk of communication interruption and provides a solid guarantee for the continuous and safe operation of the energy storage cabinet 7.

[0068] like Figure 6 As shown, a fire-fighting method for industrial and commercial energy storage cabinets with reliable monitoring described in one embodiment of the present invention is applied to the above-mentioned fire-fighting system for industrial and commercial energy storage cabinets with reliable monitoring, and includes the following steps:

[0069] S1, initialization and self-test: After the system is started, the monitoring module 2, the execution module 3, the control module 1 and its communication module 5 are initialized and self-tested to ensure that each module is working properly. The temperature sensor 201, the smoke sensor 202 and the like in the monitoring module 2 begin to monitor the internal environmental parameters of the energy storage cabinet 7.

[0070] S2, data collection and transmission: The monitoring module 2 collects the temperature, smoke and other data in the energy storage cabinet 7 in real time, and transmits the collected data to the control module 1 through the local communication unit (such as CAN or RS485). At the same time, the wired communication device and the wireless communication device in the remote communication unit are also in working state, communicating with the adjacent energy storage cabinet 7 and the host computer 6 in real time.

[0071] S3, data processing and evaluation: After receiving the data from the monitoring module 2, the control module 1 analyzes and processes the data to evaluate the current state of the energy storage cabinet 7, such as whether the temperature is too high, whether smoke is generated, etc. Based on the evaluation results, the control module 1 will make corresponding decisions and send control instructions to the execution module 3.

[0072] S4, execute control instructions: If the evaluation result shows that the energy storage cabinet 7 has safety hazards (such as overtemperature, smoke generation), the control module 1 will send control instructions to the execution module 3 through the local communication unit. The execution module 3 performs corresponding operations according to the received instructions, starts the fire extinguishing device 301 to put out the initial fire, and adjusts the thyristor 302 to control the circuit on and off, so as to ensure the safe and stable operation of the energy storage cabinet 7.

[0073] S5. Remote communication and coordination: The wired communication device in the remote communication unit is connected to the adjacent energy storage cabinet 7 to realize the mutual transmission of status information. In an emergency, if the communication module 5 of a certain energy storage cabinet 7 is damaged, the adjacent energy storage cabinet 7 can take over and send the alarm information to the host computer 6. At the same time, the wireless communication device maintains real-time communication with the host computer 6 (such as the central monitoring system), uploads the detailed operation data of the energy storage cabinet 7, and receives control instructions and scheduling information from the host computer 6. The fire extinguishing devices 301 between adjacent energy storage cabinets 7 are interconnected, so that when necessary, the adjacent energy storage cabinets 7 can be assisted in fire extinguishing, thereby enhancing the emergency response capability of the entire energy storage system.

[0074] S6, monitoring and feedback: The host computer 6 (central monitoring system) continuously receives status data from each energy storage cabinet 7, and performs comprehensive analysis and monitoring. If an abnormal situation is found or an alarm message is received, the host computer 6 will immediately take corresponding measures, such as sending an emergency notice to relevant personnel, adjusting the operation strategy of the energy storage system, etc. At the same time, the host computer 6 sends feedback instructions to the energy storage cabinet 7 to guide it to take the next action or set working parameters.

[0075] S7. Continuous monitoring and maintenance: During normal operation, the system will continue to collect, process and evaluate data to ensure the safe and stable operation of the energy storage cabinet 7.

[0076] In S3, when the monitoring data of only one sensor (temperature sensor 201 or smoke sensor 202) reaches the threshold, a first-level fire alarm is issued to the alarm module 4; when the monitoring data of at least two sensors (one temperature sensor 201 and one smoke sensor 202, or two temperature sensors 201, or two smoke sensors 202) reaches the threshold, a second-level fire alarm is issued to the alarm module 4, and a fire extinguishing instruction is sent to the execution module 3.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
