Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and particularly to an intelligent energy storage cabinet. Background Art

[0002] With the wide application of energy storage technology in fields such as power storage and distributed energy, as an important carrier of energy storage devices, the performance and safety of intelligent energy storage cabinets have attracted increasing attention.

[0003] In the existing energy storage cabinet technology, cooling and fire extinguishing are key issues to be solved. On the one hand, a large amount of heat is generated during the charging and discharging process of the battery packs in the energy storage cabinet. If the heat cannot be dissipated in time, it will cause the temperature of the battery packs to be too high, which will not only reduce the performance and service life of the batteries, but may also trigger serious safety accidents such as thermal runaway. Traditional heat dissipation methods often have low efficiency and are difficult to meet the heat dissipation requirements of the energy storage cabinet under high-load operating conditions.

[0004] On the other hand, once a fire occurs in the energy storage cabinet, due to the dense arrangement of the internal batteries and the presence of a large amount of flammable substances, the fire spreads rapidly and is difficult to extinguish. The existing fire extinguishing measures have a slow response speed and limited fire extinguishing effect, and cannot effectively control the fire in the initial stage of the fire, thus posing a great threat to the safety of the energy storage cabinet and the surrounding environment and personnel.

[0016] Working principle: In terms of heat dissipation and fire extinguishing, the pump extracts the coolant from the coolant tank and makes it circulate through the first cooling pipe and the second coolant pipe connected to the aerosol nozzle to take away the heat generated by the battery pack, etc., and reduce the temperature inside the cabinet.

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attachedFigure 1 - Appendix Figure 5 Figure 5 , an embodiment of the present invention provides an intelligent energy storage cabinet, which includes a cabinet body 1. A moisture-proof board 21 is provided at the bottom end of the inner wall of the cabinet body 1. The upper surface of the moisture-proof board 21 is provided with a number of holes. A pump 19 is provided on the upper surface of the moisture-proof board 21. The output end of the pump 19 is fixedly provided with a first cooling pipe 13. One end of the first cooling pipe 13 is provided with an aerosol spray pipe 24. The two sides of the outer wall of the aerosol spray pipe 24 are provided with second coolant pipes 20. One end of the second coolant pipes 20 is provided with a coolant tank 18. The bottom end of the coolant tank 18 is arranged on the upper surface of the moisture-proof board 21. A connecting pipe 23 is provided on the side wall of the coolant tank 18. One end of the connecting pipe 23 is arranged at the input end of the pump 19. A mist nozzle 14 is provided at the bottom end of the aerosol spray pipe 24. An aerosol box 11 is provided at the top end of the aerosol spray pipe 24. An electromagnetic valve 12 is provided on the outer wall of the aerosol spray pipe 24. The top end of the aerosol box 11 is arranged at the inner top end of the cabinet body 1; Specifically, when devices such as battery packs in the energy storage cabinet operate and generate heat, the pump 19 is started, sucking and pressurizing the coolant in the coolant tank 18 through the connecting pipe 23, and pushing the coolant into the first cooling pipe 13. Since both the first cooling pipe 13 and the second coolant pipes 20 are connected to the aerosol spray pipe 24, during the circulation of the coolant, it flows through these pipelines to absorb the heat inside the energy storage cabinet, especially the heat around the aerosol spray pipe 24. Then, the coolant with heat flows back to the coolant tank 18. The coolant continuously circulates in this closed loop, continuously taking away heat, realizing the cooling of the interior of the energy storage cabinet. When the smoke sensor 9 detects that the smoke concentration inside the energy storage cabinet reaches the preset fire warning threshold, it will send a signal to the control decision-making module. After receiving the signal, the control decision-making module immediately issues an instruction to open the electromagnetic valve 12, opening the passage between the aerosol box 11 and the aerosol spray pipe 24. At this time, the aerosol stored in the aerosol box 11 is ejected from the mist nozzle 14 at the bottom end through the aerosol spray pipe 24 in a mist form, evenly spreading in the internal space of the energy storage cabinet, covering potential fire sources and suppressing the combustion reaction. By circulating, it effectively reduces the excessively high temperature generated inside the energy storage cabinet due to the operation of devices, ensures the stable operation of devices such as battery packs in a suitable temperature environment, reduces performance loss caused by high temperature, and reduces the possibility of fire caused by high temperature from the source, making the internal environment of the energy storage cabinet safer and more stable.

[0025] Refer to Appendix Figure 2 and Appendix Figure 5, the outer wall of the cabinet body 1 is rotatably connected to the cabinet door 2 through a hinge 3. A handle 4 is provided on the outer wall of the cabinet door 2, and a temperature sensor is provided on the inner wall of the cabinet door 2. A smoke sensor 9 is provided at the top end of the inner wall of the cabinet body 1, and an explosion-proof lamp 10 is provided at the top end of the inner wall of the cabinet body 1. A contact switch 8 is provided on one side of the explosion-proof lamp 10, and the top end of the contact switch 8 is provided at the top end of the inner wall of the cabinet body 1; a heat dissipation placement board 17 is provided on the inner wall of the cabinet body 1. The upper surface of the heat dissipation placement board 17 is provided with a number of heat dissipation holes, and a number of phase change material shells 16 are provided on the upper surface of the heat dissipation placement board 17. A battery pack 15 is provided inside the phase change material shell 16; Specifically, the cabinet door 2 is rotatably connected to the cabinet body 1 through a hinge 3, which is convenient for opening and closing. A temperature sensor is provided on the inner wall of the cabinet door 2. When the cabinet door is closed, the temperature sensor can come into contact with the air environment inside the cabinet in real time, sense and collect the temperature inside the cabinet at close range, and transmit the collected temperature data to the corresponding control decision-making module and data processing module, etc. The explosion-proof lamp 10 is installed at the top end of the inner wall of the cabinet body 1, and a contact switch 8 is provided on one side of it. When the cabinet door 2 is opened, it will touch the contact switch 8, causing the state of the contact switch 8 to change, thereby triggering the conduction of the circuit and turning on the explosion-proof lamp 10; when the cabinet door 2 is closed, the contact switch 8 returns to its initial state, the circuit is disconnected, and the explosion-proof lamp 10 goes out. A heat dissipation placement board 17 is provided on the inner wall of the cabinet body 1, which has a number of heat dissipation holes. The battery pack 15 is placed inside the phase change material shell 16, and the phase change material shell 16 is placed on the upper surface of the heat dissipation placement board 17. The heat generated by the operation of the battery pack 15 will first be transferred to the phase change material in the phase change material shell 16. The phase change material can undergo a phase change at a specific temperature, absorbing or releasing a large amount of heat to regulate the temperature. At the same time, a part of the heat will pass through the heat dissipation holes on the heat dissipation placement board 17 and exchange heat with the air inside the cabinet in the ways of heat conduction and heat convection, and then dissipate to the external environment of the cabinet, realizing a multi-way heat dissipation method. Using the characteristics of the phase change material to regulate the temperature of the battery pack, delaying the rapid rise of the temperature, and then combining with the heat dissipation effect of the heat dissipation holes, effectively reducing the temperature around the battery pack and improving the heat dissipation efficiency of the entire energy storage cabinet.

[0026] Refer to the appendix Figure 6 - appendix Figure 8 , a dehumidifier 7 is provided on the upper surface of the moisture-proof board 21. A heat dissipation fan 6 is provided at the top end of the dehumidifier 7, and the outer wall of the heat dissipation fan 6 is provided on one side of the cabinet body 1. A water guide groove 22 is provided at the bottom end of the inner wall of the cabinet body 1, and a number of drain holes 5 are provided on one side of the water guide groove 22; Specifically, the dehumidifier 7 is arranged on the upper surface of the moisture-proof board 21. When it works, through internal dehumidification mechanisms such as condensation and adsorption (specifically depending on the type of dehumidifier. For example, condensation dehumidification uses a refrigeration system to lower the air temperature below the dew point temperature, and the water vapor condenses into liquid water and is discharged; adsorption dehumidification relies on hygroscopic materials to adsorb moisture in the air), the air inside the cabinet 1 is processed to remove the water vapor in the air. The radiator fan 6 is arranged at the top of the dehumidifier 7 and its outer wall is located on one side of the cabinet 1. After the radiator fan 6 is started, it can accelerate the air flow inside the cabinet 1, prompt the air containing more water vapor to enter the dehumidifier 7 for dehumidification treatment more quickly, and at the same time enable the dry air after dehumidification to circulate rapidly inside the cabinet, making the humidity inside the entire cabinet more uniform. A water guide groove 22 is arranged at the bottom end of the inner wall of the cabinet 1. When the dehumidifier 7 works or condensed water and other liquid water are generated inside the cabinet for other reasons, these waters will flow to the water guide groove 22 and gather under the action of gravity. A number of drain holes 5 are arranged on one side of the water guide groove 22. The water gathered in the water guide groove 22 will be discharged outside the cabinet 1 through these drain holes 5, preventing water from accumulating inside the cabinet. By timely and orderly discharging the excess water generated inside the cabinet, it prevents moisture from remaining inside the cabinet, further ensuring the dryness of the internal environment of the cabinet and avoiding damage such as soaking and corrosion to the moisture-proof board and electrical components at the bottom of the cabinet caused by water accumulation.

[0027] Refer to the appendix Figure 4 - appendix Figure 9 , an intelligent energy storage cabinet system, including a monitoring module, a control decision-making module, a data processing module, a communication module, and an alarm module. The monitoring module is used to obtain the status information of the intelligent energy storage cabinet in real time and provide data support. The control decision-making module is used to make control decisions on the heat dissipation, dehumidification, fire extinguishing, and lighting systems of the intelligent energy storage cabinet according to the data of the monitoring module. The data processing module is used to summarize, analyze, and store the data collected by each monitoring unit of the intelligent energy storage cabinet. The communication module is used to realize data transmission and interaction. The alarm module is used to send out a sound and light alarm through the sound and light alarm unit when an abnormal situation occurs in the intelligent energy storage cabinet to remind the on-site personnel to pay attention; The monitoring module includes a status monitoring unit, a smoke monitoring unit, a temperature monitoring unit, and a humidity monitoring unit. The status monitoring unit is used to monitor the status of specific aspects of the intelligent energy storage cabinet in real time and accurately feedback relevant information to the data processing center. The smoke monitoring unit is used to detect the smoke concentration inside the intelligent energy storage cabinet in real time. When the detected smoke concentration exceeds the preset threshold, it timely sends out a warning signal to the alarm module and the control decision-making module. The temperature monitoring unit is used to collect the temperature data of the battery pack 15 and key parts inside the intelligent energy storage cabinet. The humidity monitoring unit is used to monitor the humidity situation inside the intelligent energy storage cabinet in real time and feedback the obtained humidity data to the dehumidification control unit; Specifically, the status monitoring unit has set up various sensors and detection devices at corresponding positions inside the intelligent energy storage cabinet (such as sensors for detecting the opening and closing status of the cabinet door, sensors for monitoring the operating current and voltage of the equipment, etc.). These sensors can real-time sense the physical quantity changes in specific aspects of the intelligent energy storage cabinet (such as the operating status of the equipment, the opening and closing of the cabinet door, the connection status of each component, etc.), and convert these physical quantities into corresponding electrical signals or digital signals. Then, through the internal communication line according to the established communication protocol, the relevant information is accurately transmitted and fed back to the data processing center; the smoke monitoring unit usually uses optical sensors (such as photoelectric smoke sensors, which judge the smoke concentration by detecting the light scattering or blocking situation) or ion type smoke sensors (based on the influence of smoke particles on the ionization current to detect), etc. The principle is installed at appropriate positions inside the intelligent energy storage cabinet (such as the top of the cabinet body, near each layer of partition, etc., to ensure that each area can be effectively monitored), and the air inside the cabinet is monitored in real-time, continuously detecting the content of smoke particles in the air, so as to obtain the corresponding smoke concentration value. Once the detected smoke concentration exceeds the pre-set threshold (this threshold is set according to the actual safety requirements of the energy storage cabinet and relevant standards), an early warning signal will be immediately sent to the alarm module and the control decision-making module through the internal communication link, triggering corresponding alarm prompts and control operations such as fire extinguishing; the temperature monitoring unit has installed high-precision temperature sensors (such as thermocouples, thermal resistors and other types of sensors, which will generate corresponding resistance or potential changes with temperature changes) at key positions such as the battery pack 15 inside the intelligent energy storage cabinet and key parts such as heat dissipation components and electrical connection key parts. These sensors are connected to the data acquisition system, can real-time sense the temperature changes at the corresponding positions, and convert the temperature changes into measurable electrical signals. After signal conditioning, analog-to-digital conversion and other processing, the collected temperature data is accurately transmitted to relevant modules such as the data processing center for subsequent analysis, storage and use for control decision-making, etc.; the humidity monitoring unit has reasonably arranged humidity sensors at different positions inside the intelligent energy storage cabinet (such as using capacitive or resistive humidity sensors, whose electrical characteristics change with the change of environmental humidity). These sensors can real-time sense the humidity situation of the air inside the cabinet body, convert the humidity information into corresponding electrical signals, and then transmit them to the dehumidification control unit through the communication line, providing accurate humidity data reference for it, so that the dehumidification control unit can judge whether to start the dehumidification operation according to the pre-set humidity control range; by comprehensively, real-time and accurately mastering the status of multiple specific aspects of the intelligent energy storage cabinet, the data processing center can build a clear picture of the overall operation of the energy storage cabinet based on the received detailed status information, providing a reliable data basis for subsequent analysis, control decision-making and fault troubleshooting, etc.

[0028] The control decision-making module includes a heat dissipation control unit, a dehumidification control unit, a fire extinguishing control unit, and a lighting control unit. The heat dissipation control unit is used to regulate the heat dissipation system of the intelligent energy storage cabinet according to the temperature data fed back by the temperature monitoring unit. The dehumidification control unit is used to make a judgment based on the humidity data inside the cabinet fed back by the humidity monitoring unit. When the humidity exceeds the upper limit of the set appropriate range, it issues an instruction to start the dehumidifier 7 for dehumidification operation. The fire extinguishing control unit is used to quickly issue a control instruction for fire extinguishing after receiving a fire warning signal or other relevant fire prompt information sent by the smoke monitoring unit. The lighting control unit is used to control the turning on and off of the explosion-proof lamp 10 according to conditions such as the environmental conditions where the intelligent energy storage cabinet is located and whether an emergency occurs; Specifically, the heat dissipation control unit establishes a real-time communication connection with the temperature monitoring unit and receives the temperature data of the battery packs and key components inside the intelligent energy storage cabinet fed back by the temperature monitoring unit. Different temperature threshold ranges are preset inside it, corresponding to different heat dissipation regulation strategies. When the received temperature data shows that the current temperature is within the normal range, the heat dissipation control unit maintains the current operating state of the heat dissipation system (for example, keeping the existing rotation speed of the cooling fan, the normal flow rate of the coolant circulation system, etc.). Once the temperature data exceeds the normal range and reaches a certain threshold that requires enhanced heat dissipation, the heat dissipation control unit will issue control instructions to the corresponding heat dissipation components (such as pumps, cooling fans, etc.) according to the preset control logic, adjust the rotation speed of the pump to change the circulation speed of the coolant and accelerate the transfer of heat; or increase the rotation speed of the cooling fan to enhance the convection of the air inside the cabinet and promote the faster dissipation of heat; if the temperature continues to rise to a higher dangerous threshold, multiple enhanced heat dissipation measures may be taken simultaneously to ensure the heat dissipation effect to the greatest extent; the dehumidification control unit continuously receives the humidity data inside the intelligent energy storage cabinet fed back by the humidity monitoring unit, and stores the set appropriate humidity range value inside it (this range is determined according to the humidity tolerance of the equipment inside the energy storage cabinet and the requirements for normal operation). The dehumidification control unit will compare and judge the received real-time humidity data with the set appropriate range. When the humidity data exceeds the upper limit value of this range, it means that the humidity inside the cabinet is too high, which may cause damage to electrical equipment, etc. At this time, the dehumidification control unit will generate and issue a start command, transmit the command to the dehumidifier through the control circuit, trigger the dehumidifier to start working, and start the dehumidification mechanism inside the dehumidifier (such as condensation dehumidification, adsorption dehumidification, etc.) to remove the water vapor in the air; as the dehumidification process progresses, the humidity data will gradually decrease. When the humidity drops back to the appropriate range, the dehumidification control unit issues another command to stop the dehumidifier from working, and so on, accurately controlling the humidity inside the cabinet; the fire extinguishing control unit maintains close communication with the smoke monitoring unit and is always ready to receive the fire warning signal or other relevant fire prompt information issued by the smoke monitoring unit (such as the linkage signal from the external fire protection system, etc.). Once such a signal is received, it means that there may be a fire hazard or a fire has occurred inside the energy storage cabinet. The fire extinguishing control unit will immediately issue control instructions to the relevant fire extinguishing components (such as the solenoid valve on the aerosol nozzle, the water spraying device corresponding to the mist nozzle, etc.) according to the preset fire extinguishing control procedure.For example, the instruction will open the solenoid valve, causing the aerosol in the aerosol cartridge to be ejected from the atomizing nozzle through the aerosol spray pipe and covering the possible fire source to inhibit the combustion reaction. At the same time, it may also activate other supporting fire extinguishing medium release devices to work together to quickly extinguish the fire and control the spread of the fire, minimizing the damage caused by the fire to the energy storage cabinet and the surrounding environment. The lighting control unit will make control decisions by comprehensively considering the environmental conditions of the intelligent energy storage cabinet (such as whether it is in a dimly lit place, whether there is external occlusion resulting in insufficient light inside the cabinet, etc.) and whether an emergency occurs (such as a fire alarm trigger, equipment failure alarm, etc.). It establishes connections with relevant sensors (such as light sensors, smoke sensors, fault alarm devices, etc.) to obtain corresponding environmental and alarm information. Under normal circumstances, if the ambient light is dim, the lighting control unit will judge according to the preset light threshold and issue an instruction to turn on the explosion-proof lamp to provide necessary lighting for the operator, facilitating operations such as operating and inspecting the energy storage cabinet. When an emergency occurs, regardless of the current ambient light, the lighting control unit will immediately issue an instruction to turn on the explosion-proof lamp to ensure sufficient light at the scene, facilitating personnel evacuation, checking for faults, and carrying out emergency response work. When the ambient light is sufficient and there is no emergency, the lighting control unit controls the explosion-proof lamp to be in the off state to save energy. Through the intelligent and precise regulation of the heat dissipation system of the intelligent energy storage cabinet, the heat dissipation intensity can be dynamically adjusted according to the actual temperature situation, ensuring that the internal temperature of the energy storage cabinet always remains within the range suitable for the normal operation of the battery pack and other equipment, avoiding adverse effects on the equipment performance and lifespan due to excessive temperature, and also avoiding unnecessary energy waste.

[0029] The data processing module includes a data acquisition unit, a data analysis unit, and a data storage unit. The data acquisition unit is used to collect relevant data obtained by each monitoring unit of the intelligent energy storage cabinet, aggregating various dispersed operation status information. The data analysis unit is used to deeply analyze various operation data of the intelligent energy storage cabinet aggregated by the data acquisition unit. The data storage unit is used to save various data generated during the operation of the intelligent energy storage cabinet. Specifically, the data acquisition unit establishes a communication link with each monitoring unit in the smart energy storage cabinet (such as the status monitoring unit, smoke monitoring unit, temperature monitoring unit, humidity monitoring unit, etc.), and uses standard data transmission protocols (such as Modbus, TCP / IP and other protocols, selected according to the actual application scenario and system architecture) to achieve data interaction with each monitoring unit. The operating status information of different aspects of the smart energy storage cabinet obtained by each monitoring unit in real time (such as the equipment operating parameters and cabinet door status data obtained by the status monitoring unit, the smoke concentration value detected by the smoke monitoring unit, the temperature value collected by the temperature monitoring unit, the humidity feedback from the humidity monitoring unit, etc.) will be transmitted to the data acquisition unit through the communication link in accordance with the established format and frequency. After receiving these scattered data, the data acquisition unit will organize them in a unified format, mark the source, and add timestamps, and then summarize and integrate all relevant operating status information in an orderly manner to form a complete data set; after the data analysis unit obtains the various operating data of the intelligent energy storage cabinet summarized and organized by the data acquisition unit, it will first use data cleaning technology to remove possible erroneous data, duplicate data, and outliers (such as unreasonable data occasionally generated by sensor failures, etc.) to ensure data quality. Then, according to different analysis purposes and data types, select appropriate data analysis methods and algorithms. For example, for data that changes over time such as temperature and humidity, use time series analysis to mine data change trends and periodic laws; for correlation analysis between the operating states of different components, use statistical methods such as correlation analysis; for complex needs such as fault prediction, use machine learning algorithms (such as support vector machines, neural networks, etc.) to build prediction models. Through these analytical methods, the information contained in the data is deeply analyzed to dig out deep-level contents such as whether the equipment is operating normally, whether there are potential fault hazards, the relationship between various parameters, and possible future operating trends. The data storage unit uses appropriate storage media (such as hard disks, solid-state drives, etc.) and database management systems (such as relational databases MySQL, non-relational databases MongoDB, etc., selected according to data characteristics and storage requirements) to create corresponding storage structures and data tables for various types of data generated during the operation of the intelligent energy storage cabinet. When receiving data that needs to be stored (these data come from the data sets summarized by the data acquisition unit or valuable data processed by the data analysis unit, etc.), the data storage unit will write the data accurately to the corresponding storage location according to the pre-set storage rules (such as storage according to data type classification, storage in chronological order, etc.), and establish an effective indexing mechanism to facilitate subsequent data query and retrieval.Meanwhile, to ensure the security and integrity of data, measures such as regular data backup, redundant storage technology, and access permission settings are also taken to prevent data loss, damage, or unauthorized access. By centrally collecting the full-range operation status data of the intelligent energy storage cabinet, the data originally scattered in various monitoring units with different formats and sources are standardized and integrated to construct a comprehensive dataset that can reflect the overall operation of the energy storage cabinet, providing an accurate and complete data foundation for subsequent data analysis, storage, and management decision-making of the entire energy storage cabinet system.

[0030] The communication module includes an internal communication unit and an external communication unit. The internal communication unit is used to ensure data transmission and instruction interaction between the internal functional modules of the intelligent energy storage cabinet, and the external communication unit is used to establish a communication connection between the intelligent energy storage cabinet and the external system and transmit the real-time operation status information, alarm conditions, etc. of the energy storage cabinet outward. Specifically, the internal communication unit builds the communication network inside the intelligent energy storage cabinet based on specific communication technologies and protocols. Common communication technologies include CAN bus, industrial Ethernet, etc. Taking the CAN bus as an example, it operates in a multi-master mode, and each functional module (such as each monitoring unit in the monitoring module, each control unit in the control decision-making module, and the data acquisition, analysis, and storage units included in the data processing module) is connected to the CAN bus as a node, and each node has a unique identifier. When a functional module needs to send data or instructions, it will package the relevant information according to the frame format specified by the CAN bus (including identifier, data segment, check bit, etc.), and then send it to the bus. Other nodes on the bus judge whether to receive the information by identifying the identifier, thus realizing the directional transmission of data and the instruction interaction between modules. Industrial Ethernet uses Ethernet technology and follows protocols such as TCP / IP. Each functional module is connected to the internal Ethernet through a network interface, and data exchange and transmission are achieved with the help of network devices such as switches to ensure that information is accurately delivered to the corresponding module; the external communication unit is connected to the external system through multiple communication interfaces. Common communication methods include wired communication (such as optical fiber communication, Ethernet, etc.) and wireless communication (such as 4G / 5G networks, LoRa, Zigbee, etc., which are selected according to the actual application scenario and requirements such as distance and bandwidth). In terms of wired communication, if optical fiber communication is used, it uses the total internal reflection of light in the optical fiber to transmit optical signals, converts the electrical signal into an optical signal through optoelectronic conversion equipment for long-distance transmission, and then restores the optical signal to an electrical signal at the receiving end to achieve a high-speed and stable connection with external systems (such as the background management system, remote monitoring center, etc.); Ethernet is based on network cable connection and conducts data interaction following network protocols.For wireless communication, taking the 4G / 5G network as an example, the communication module at the intelligent energy storage cabinet end is built with corresponding communication chips. By establishing a wireless link with a nearby base station, it encapsulates and encrypts data such as the real-time operation status information of the energy storage cabinet (e.g., data collected by each monitoring unit, working status of each functional module, etc.) and alarm situations (fire alarm, equipment failure alarm, etc.) according to a specific communication protocol and then sends it out. External relevant systems (such as the mobile terminals of operation and maintenance personnel, remote monitoring platforms, etc.) perform unpacking and decryption operations after receiving the signal to obtain the corresponding information; Wireless communication technologies such as LoRa and Zigbee are applicable to short-distance and low-power communication scenarios. Similarly, they can transmit relevant information of the energy storage cabinet to external devices or gateways at close range, and then the gateway forwards it to a more remote system. Through the efficient, stable, and accurate data transmission and instruction interaction among the internal functional modules of the intelligent energy storage cabinet, the smooth flow of information within the entire energy storage cabinet system is ensured, enabling the monitoring data to be timely transmitted to the data processing and control decision-making module, and the control instructions to be quickly and accurately sent to the corresponding execution unit. Each module can work in coordination to jointly maintain the normal operation status of the energy storage cabinet, improving the overall operation efficiency and coordination of the system.

[0031] The alarm module includes an audible and visual alarm unit and a remote alarm unit. The audible and visual alarm unit is used to immediately attract the attention of on-site personnel by emitting obvious audible and visual signals when abnormal situations occur in the intelligent energy storage cabinet. The remote alarm unit is used to send alarm information to relevant remote personnel or systems through network communication technologies when abnormal conditions occur in the intelligent energy storage cabinet; Specifically, the acoustic-optic alarm unit is installed and laid out at key positions inside the intelligent energy storage cabinet. It is usually equipped with a sound alarm (such as a high-decibel buzzer, etc.) and a light alarm (such as a high-brightness warning light, etc.). When the monitoring module inside the intelligent energy storage cabinet (such as the smoke monitoring unit detects that the smoke concentration exceeds the standard, the temperature monitoring unit finds that the temperature rises abnormally, etc.) detects an abnormal situation, the relevant monitoring unit will send the abnormal signal to the control decision-making module. After the control decision-making module judges and confirms, it will send a trigger instruction to the acoustic-optic alarm unit. Once receiving this instruction, the sound alarm will, based on the internal circuit drive mechanism, cause the vibrating diaphragm and other sound-generating components to vibrate, and then emit a high-decibel, warning sound. This sound usually has a specific frequency and loudness, and can be relatively prominent even in a noisy environment. At the same time, the light-emitting element (such as an LED lamp bead, etc.) in the light alarm will emit strong flashing light after the circuit is turned on. Its flashing frequency and color are usually set according to the standard that is easy to attract people's attention, such as using eye-catching red flashing light. The acoustic and optical signals are sent synchronously, thus forming an obvious acoustic-optic warning effect around the cabinet body and immediately attracting the attention of on-site personnel. The remote alarm unit is built-in with corresponding network communication modules (which can use 4G / 5G network communication chips, Ethernet communication modules, etc. according to the actual application scenario), and the communication connection parameters (including IP address, port number, communication protocol, etc.) with remote relevant personnel or systems (such as the mobile terminal of the operation and maintenance personnel, the server of the remote monitoring center, etc.) are pre-configured. When the monitoring module inside the intelligent energy storage cabinet detects an abnormal situation, such as the generation of a fire warning signal, the triggering of a key equipment failure signal, etc., the relevant abnormal information will be transmitted to the control decision-making module, and the control decision-making module will immediately issue an instruction to the remote alarm unit to send the alarm information. After receiving the instruction, the remote alarm unit will, according to the set communication protocol, pack and encrypt the data containing the specific content of the abnormal situation (such as the type of failure, the location of occurrence, the abnormal parameter value, etc.), and then send the alarm information accurately to the remote relevant personnel or system through the established network communication link (such as sending it to the cloud server via 4G / 5G network and then forwarded by the cloud server to the corresponding operation and maintenance personnel's mobile APP; or directly sending it to the server of the remote monitoring center via Ethernet, etc.). After receiving the information, the relevant receiving party will perform operations such as unpacking and decryption to obtain the specific alarm details. Through the immediate and eye-catching alarm prompt at the site where the intelligent energy storage cabinet is located, on-site personnel can, whether they are operating or patrolling at close range or in the surrounding area at a slightly longer distance, immediately notice that there is an abnormal situation in the energy storage cabinet by hearing the sharp alarm sound and seeing the flashing warning light, which is convenient for quickly taking corresponding countermeasures, such as checking the specific cause of the failure, starting the emergency handling process, organizing personnel evacuation, etc., to minimize the harm that the abnormal situation may bring. Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
