The power module 70 is used to provide power for all modules, and is connected to the processing module 10, the communication module 20, the composite fire detection module 30, the voltage acquisition module 40, the temperature acquisition module 50 and the equalization module 60 respectively.

[0030] It should be noted that the composite fire detection module and the communication module, the voltage acquisition module, the temperature acquisition module and the equalization module share one processing module and one power module in the embodiment, and the above integrated design is adopted, so that the integrated temperature acquisition, voltage acquisition and fire detection module design is realized, and the integration of the system is improved.

[0031] In specific embodiments, the processing module can integrate machine learning algorithms to improve the accuracy and response speed of fire detection. The communication module can integrate wireless communication functions such as Wi-Fi or Bluetooth to enable longer-distance data transmission and reduce wiring complexity. In addition, each module can integrate self-diagnosis functions to regularly check its own state and promptly discover and report potential faults. Each module can also be designed as a plug-in design to facilitate later maintenance and upgrades.

[0032] The present embodiment reduces the number of system components, simplifies the system structure, and reduces material and manufacturing costs through the integration of multiple modules in a slave device.

Modular design makes it easier to maintain and upgrade later, reducing maintenance costs.

[0033] Optionally, as shown in some embodiments, the slave device can further include a connector module 80, one end of the connector module 80 being connected to the voltage acquisition module 40, the temperature acquisition module 50, and the balancing module 60, respectively. Figure 1

[0034] Specifically, the slave device in the present embodiment further includes a connector module 80, one end of the connector module 80 being connected to the voltage acquisition module 40, the temperature acquisition module 50, and the balancing module 60, respectively.

[0036] As can be seen, the connector module provided by the present embodiment can simplify the installation and maintenance process of the slave device and improve work efficiency; high-reliability connectors reduce connection failures and improve the stability and reliability of the entire system; modular design makes the system more flexible, allowing components to be quickly replaced or upgraded as needed; modular design also reduces maintenance costs, as a single module failure will not affect the entire system and the faulty module can be replaced individually.​

[0037] Optionally, in some embodiments, the slave device further comprises a power converter, one end of the power converter is connected to the power module, and the other end of the power converter is connected to the processing module, the communication module, the composite fire detection module, the voltage acquisition module, the temperature acquisition module and the balancing module respectively.

[0038] Specifically, the slave device in the embodiment further provides a power converter, one end of the power converter is connected to the power module, and the other end of the power converter is connected to the processing module, the communication module, the composite fire detection module, the voltage acquisition module, the temperature acquisition module and the balancing module.

[0041] In addition, the power converter can also be designed with a redundant power system to improve the reliability and fault tolerance of the system, ensuring that critical modules can continue to work when the main power fails. Through an intelligent power distribution system, the power distribution can be dynamically adjusted according to the real-time needs of each module to optimize energy use.

[0042] As can be seen, the power converter in the embodiment reduces energy loss in the energy conversion process through high-efficiency power conversion technology, improving energy utilization efficiency. Through the use of the power converter, each module can obtain stable and suitable power, improving the reliability of the system. Multi-level power management enables the system to adapt to different module power requirements, enhancing the flexibility of the system. Redundant power design improves the fault tolerance of the system, so that critical modules can continue to work even in the event of main power failure, improving system safety. The intelligent power distribution system can dynamically adjust power distribution according to the actual needs of each module to further optimize energy use and reduce unnecessary energy consumption.

[0043] Optionally, in some embodiments, the slave device is provided with a ventilation hole on the outer plastic shell.

[0044] Specifically, the slave device provided by the embodiment further comprises an external plastic shell, and a plurality of air vents are arranged on the external plastic shell. The external plastic shell is a shell for protecting internal components of the slave device, which not only provides physical protection, but also has the functions of dustproof, waterproof, and corrosion-proof. The air vents are arranged on the external plastic shell to allow air to circulate while preventing liquid and large particles of dust from entering. The air vents balance the air pressure inside and outside, prevent the deformation or damage of the plastic shell caused by the air pressure difference, and also help dissipate heat and keep the internal components dry.

[0045] In specific embodiments, the air vents can be made of special filter materials, such as air-permeable membranes or metal meshes, to improve air permeability and dustproof and waterproof levels. In combination with the air vents, specific heat dissipation structures, such as heat sinks or heat dissipation channels, are designed to improve the heat dissipation efficiency of the slave device. The design of the air vents takes into account the adaptability to different environmental conditions, such as high humidity or dusty environments, to ensure that the slave device can work stably in various environments.

[0046] The embodiment can achieve air circulation without sacrificing the protection level, improve the environmental adaptability of the slave device, and help dissipate heat, reduce the risk of overheating of internal components, and improve the stability and reliability of the slave device. The air vents can balance the air pressure inside and outside, prevent the deformation or damage of the plastic shell caused by the air pressure difference, and protect the internal components. The design of the air vents reduces the accumulation of internal humidity caused by environmental changes, prolonging the service life of the slave device.

[0047] Optionally, as shown in Figure 2 some embodiments, the slave device is connected to one end of the electromagnetic valve of the fire pipe through a digital output channel, and the other end of the electromagnetic valve is connected to the fire liquid storage tank.

[0048] Specifically, as shown in Figure 2 the slave device in the embodiment further integrates a digital output (DO) channel, and the slave device is connected to one end of the electromagnetic valve of the fire pipe through the digital output (DO) channel. The digital output channel sends control signals to the electromagnetic valve to control the opening and closing of the electromagnetic valve. One end of the electromagnetic valve is connected to the digital output channel of the slave device, and the other end is connected to the fire liquid storage tank. The electromagnetic valve opens or closes when receiving the control signal to control the flow of fire extinguishing liquid. One end of the fire liquid storage tank is connected to the electromagnetic valve of the fire pipe. The function of the storage tank is to store fire extinguishing liquid, which can be released to the area where fire extinguishing is needed when the electromagnetic valve is opened.

[0049] In addition, the slave device can integrate intelligent control algorithms, allowing the digital output channel to more accurately control the opening and closing of the electromagnetic valve to adapt to different fire situations. The digital output channel can integrate remote monitoring functions, allowing operators to control the electromagnetic valve from a safe distance, improving safety. The digital output channel can integrate fault diagnosis functions to monitor the status of the electromagnetic valve in real time and provide feedback when problems occur.

[0050] This embodiment ensures quick response and timely release of fire extinguishing liquid in the event of a fire through direct connection of the digital output channel with the electromagnetic valve. Precise control of the digital output channel can reduce the risk of misoperation and improve the safety of the entire fire protection system. Not only can it eliminate the need for a traditional fire protection host, reducing the cost of energy storage integration, but it can also improve the space utilization of the system, thereby increasing the energy density. Moreover, direct control of the digital output channel simplifies the fire control logic, making the system more concise and efficient.

[0051] Optionally, in some embodiments, the composite fire detection module includes at least one of a smoke detection unit, a temperature detection unit, a flame detection unit, a gas detection unit, an image recognition unit, a sound detection unit, a pressure detection unit, and an optical fiber detection unit.

The composite fire detection module can specifically include at least one of a smoke detection unit, a temperature detection unit, a flame detection unit, a gas detection unit, an image recognition unit, a sound detection unit, a pressure detection unit, and an optical fiber detection unit. The processing module receives signals from the composite fire detection module and makes corresponding control decisions based on these signals. The processing module uploads the fire signal to the upper-level master control module through the communication module and controls the electromagnetic valve to extinguish the fire.

[0053] The smoke detection unit can include a photoelectric smoke detector and a laser smoke detector. The photoelectric smoke detector detects smoke particles in the air using light scattering principles. The laser smoke detector uses laser technology to detect smoke in the air. The temperature detection unit can include a constant temperature detector and a differential temperature detector. The constant temperature detector triggers an alarm at a specific temperature and is suitable for detecting high-temperature fires. The differential temperature detector detects rapid changes in ambient temperature and is suitable for rapid fire spread situations.

[0054] In specific embodiments, multi-sensor fusion technology can also be achieved by integrating multiple detection units, improving the accuracy and response speed of fire detection. Artificial intelligence algorithms are used to analyze detection data to identify early signs of fire and respond more quickly. The composite fire detection module can use wireless communication technology to reduce wiring complexity and improve system flexibility and reliability.

[0055] The composite fire detection module of the present embodiment integrates multiple detection units to detect fires from multiple dimensions, improving detection accuracy. The application of multi-sensor fusion technology and artificial intelligence algorithms enables the system to quickly identify and respond to fires. Wireless communication technology reduces wiring and maintenance workload, reducing system maintenance costs. By detecting fires in a timely and accurate manner and controlling the fire extinguishing system, the safety of the entire energy storage system is improved.

[0057] Specifically, this embodiment also provides a fire management system including a master control device and several slave control devices. The master control device, as the center of the fire management system, is responsible for receiving data sent from each slave control device and making global control decisions based on the received data. Each slave control device is connected to the master control device and is responsible for monitoring and managing the fire safety of its corresponding battery pack. The slave control devices communicate with the master control device through a serial communication protocol bus interface to transmit fire detection data and receive control commands. The serial communication protocol bus interface supports real-time data transmission, ensuring the system's response speed and control efficiency. In addition, more advanced serial communication protocols, such as CANopen or Modbus, can be used to improve communication reliability and real-time performance.

[0058] Furthermore, in practical applications, encryption and authentication mechanisms can be integrated into the communication protocol to prevent unauthorized access and data tampering, thereby enhancing system security. Remote monitoring and diagnostic functions can be achieved via the internet or wireless networks, enabling managers to monitor the status of the fire management system from any location. Utilizing data collected from slave devices, the master control unit can also employ machine learning algorithms for fault prediction and health status monitoring.

[0059] This embodiment utilizes a serial communication protocol bus interface, enabling the master control device to quickly receive data from the slave control devices, thus improving the response speed of the entire fire management system. Advanced communication protocols and network security measures enhance the reliability of data transmission and the security of the system. Remote monitoring and diagnostic functions allow maintenance personnel to remotely identify and resolve problems, reducing the need for on-site inspections and improving maintenance efficiency. The modular design of the slave and master control devices allows for easy addition or removal of slave control devices as needed, improving the system's flexibility and scalability.

[0060] Optionally, such as Figure 3 As shown, in some embodiments, the fire management system further includes several battery packs, each of which is connected to a corresponding slave control device.

[0061] Specifically, the fire management system in this embodiment also includes several battery packs that need to be monitored. Each battery pack is connected to a corresponding slave control device, which is responsible for monitoring the status of the battery pack, such as temperature and voltage, and activating corresponding fire-fighting measures when an abnormality is detected. Wireless communication technology is used between the slave control device and the battery pack, reducing wiring between them and improving the system's flexibility and scalability. With the integration of an intelligent BMS, the slave control device can monitor battery status more accurately, enabling battery health management and optimization. The master control device can also integrate energy management functions to optimize the battery pack's charging and discharging strategies and improve energy utilization efficiency.

[0062] This embodiment enables real-time monitoring of the battery pack by the slave control device, which can promptly detect fire hazards and improve the safety of the entire fire management system.
