[0027] See also Figure 1 , Figure 1 A schematic diagram of the structure of a slave control device provided in an embodiment of the present application.

[0028] In this embodiment, a slave control device is provided, which may specifically include a processing module 10, a communication module 20, a composite fire detection module 30, a voltage acquisition module 40, a temperature acquisition module 50, a balancing module 60 and a power supply module 70; wherein one end of the processing module 10 is respectively connected to the communication module 20, the composite fire detection module 30, the voltage acquisition module 40, the temperature acquisition module 50 and the balancing module 60; one end of the power supply module 70 is respectively 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 balancing module 60.

[0029] Specifically, the processing module 10 serves as the center of the slave control device, and the processing module is responsible for receiving and processing data and signals from each module. One end of the processing module 10 is respectively connected to 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. The communication module 20 is responsible for data exchange with the master control device, which is realized through the serial communication protocol bus interface, and is connected to the processing module to transmit fire detection information and battery status information. The composite fire detection module 30 includes one or more of a variety of detection units such as smoke, temperature, flame, gas, image recognition, sound, pressure and optical fiber. It is connected to the processing module to monitor the status of the battery pack in real time. Once an abnormality (such as thermal runaway) is detected, a signal is immediately sent to the processing module. The voltage acquisition module 40 is connected to the processing module 10 to monitor the voltage status of the battery, ensure that the battery operates within a safe voltage range, and prevent overcharging or undercharging. The temperature acquisition module 50 is also connected to the processing module to monitor the temperature of the battery to prevent safety problems caused by overheating. The balancing module 60 is connected to the processing module 10 and is used for balancing management of the battery pack, adjusting the power of each battery in the battery pack, maintaining the balanced state of the battery pack, and thus extending the battery life. The power module 70 is used to provide power to all modules and is respectively 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 balancing module 60.

[0030] It should be noted that this embodiment uses the above-mentioned integrated design by having the composite fire detection module and the communication module, the voltage acquisition module, the temperature acquisition module, and the balancing module share a processing module, and having the composite fire detection module and the communication module, the voltage acquisition module, the temperature acquisition module, and the balancing module share a power supply module, thereby improving the system's integration by adopting an integrated design of temperature acquisition, voltage acquisition, and fire detection modules.

[0031] In a specific embodiment, the processing module can integrate a machine learning algorithm 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 achieve longer-distance data transmission and reduce the complexity of wiring. In addition, each module can integrate a self-diagnosis function to regularly check its own status and promptly detect and report potential faults. Each module can also be designed as a pluggable design to facilitate later maintenance and upgrades.

[0032] This embodiment reduces the number of system components and simplifies the system structure by integrating multiple modules into one slave control device. The integrated design reduces material and manufacturing costs, and reduces the workload of installation and maintenance. The multiple detection units of the composite fire detection module can monitor the battery status more comprehensively, detect and handle safety issues in a timely manner; the balancing module can optimize the working status of the battery pack and improve energy efficiency; through modular design and intelligent control, the system can operate more stably and reliably, improving the reliability of the system; modular design makes subsequent maintenance and upgrades more convenient, reducing maintenance costs.

[0034] Specifically, the slave control device in this embodiment further includes a connector module 80, one end of which is respectively connected to the voltage acquisition module 40, the temperature acquisition module 50 and the balancing module 60. The connector module 80 serves as a bridge connecting each module with the external system, providing a fast and reliable connection method for the slave control device, which is convenient for installation and maintenance.

[0035] In a specific embodiment, high-reliability connector technology, such as gold contacts or high-performance connectors, is used to reduce the problems of poor contact and signal interference. The connector module can also be designed to be modular, so that the voltage acquisition module, temperature acquisition module and equalization module can be easily replaced or upgraded, thereby improving the flexibility and maintainability of the system. In addition, through the connector module, remote monitoring and diagnosis functions can also be realized to monitor the status of the battery pack in real time, and problems can be discovered and solved in a timely manner.

[0036] It can be seen that the connector module provided in this embodiment can simplify the installation and maintenance process of the slave control device and improve work efficiency; the high-reliability connector reduces connection failures and improves the stability and reliability of the entire system; the modular design makes the system more flexible and facilitates the rapid replacement or upgrading of components as needed; the modular design can also reduce maintenance costs, because the failure of a single module will not affect the entire system, and the faulty module can be replaced individually.

[0037] Optionally, in some embodiments, the slave control device also includes a power converter, one end of the power converter is connected to the power module, and the other end of the power converter is respectively 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.

[0038] Specifically, the slave control device in this embodiment further provides a power converter, one end of which is connected to the power module, and the other end 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. The main function of the power converter is to convert the power provided by the power module into the voltage and current required for the operation of each module.

[0039] It should be noted that the power module in this embodiment also includes a backup power supply. In the event of an AC power outage, the DC 24V backup power supply can supply power to ensure that the system is in working condition, thereby improving the reliability of the system.

[0040] In a specific embodiment, the power converter adopts high-efficiency power conversion technology, such as switching power supply technology, to reduce energy loss and improve energy utilization, and implements multi-level power management to meet the different requirements of different modules for power stability and voltage level.

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

[0042] It can be seen that the power converter in this embodiment reduces the loss in the energy conversion process and improves the energy utilization efficiency through efficient power conversion technology. Through the use of the power converter, it is ensured that each module can obtain a stable and appropriate power supply, thereby improving the reliability of the system. Multi-level power management enables the system to adapt to the power requirements of different modules and enhances the flexibility of the system. The redundant power supply design improves the fault tolerance of the system. Even in the event of a main power failure, the key modules can continue to work, thereby improving the safety of the system. The intelligent power distribution system can dynamically adjust the power distribution according to the actual needs of each module, further optimize energy use, and reduce unnecessary energy consumption.

[0043] Optionally, in some embodiments, ventilation holes are provided on the outer plastic shell of the slave control device.

[0044] Specifically, the slave control device provided in this embodiment also includes an external plastic shell, and a plurality of air holes are provided on the external plastic shell. The external plastic shell is an outer shell that protects the internal components of the slave control device, which not only provides physical protection, but also has dustproof, waterproof and anti-corrosion functions. The air holes are provided on the external plastic shell to allow air circulation while preventing liquids and large dust particles from entering. The function of the air holes is to balance the internal and external air pressures to prevent deformation or damage of the plastic shell due to air pressure differences, and also to help dissipate heat and keep the internal components dry.

[0045] In a specific embodiment, the air holes can be made of special filter materials, such as air permeable membranes or metal meshes, to improve the air permeability and dust and water resistance level. In combination with the air holes, a specific heat dissipation structure, such as a heat sink or a heat dissipation channel, is designed to improve the heat dissipation efficiency of the slave control device. The design of the air holes takes into account the adaptability to different environmental conditions, such as high humidity or dusty environments, to ensure that the slave control device can work stably in various environments.

[0046] By providing ventilation holes on the external plastic shell, this embodiment can achieve air circulation without sacrificing the protection level, thereby improving the environmental adaptability of the slave control device; the ventilation holes help to dissipate heat, reduce the risk of overheating of internal components, and improve the stability and reliability of the slave control device; the ventilation holes can balance the internal and external air pressure, prevent deformation or damage of the plastic shell due to air pressure differences, and protect internal components; the design of the ventilation holes reduces the accumulation of internal humidity caused by environmental changes, thereby extending the service life of the slave control device.

[0047] Alternatively, if Figure 2 As shown, in some embodiments, the slave control device is connected to one end of the solenoid valve of the fire protection pipeline through a digital output channel, and the other end of the solenoid valve is connected to the fire protection liquid storage tank.

[0048] Specifically, Figure 2 As shown, the slave control device in this embodiment is also integrated with a digital output (DO) channel, and the slave control device is connected to one end of the solenoid valve of the fire-fighting pipe through the digital output (DO) channel. The function of the digital output channel is to send a control signal to the solenoid valve to control the opening and closing of the solenoid valve. One end of the solenoid valve is connected to the digital output channel of the slave control device, and the other end is connected to the fire-fighting liquid storage tank. The function of the solenoid valve is to open or close when receiving a control signal to control the flow of the fire-fighting liquid. One end of the fire-fighting liquid storage tank is connected to the solenoid valve of the fire-fighting pipe. The function of the storage tank is to store fire-fighting liquid. When the solenoid valve is opened, the fire-fighting liquid can be released to the area where fire extinguishing is required.

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

[0050] This embodiment ensures a quick response and timely release of fire extinguishing liquid when a fire occurs by directly connecting the digital output channel to the solenoid valve; the precise control of the digital output channel can reduce the risk of misoperation and improve the safety of the entire fire protection system. It not only eliminates the need for traditional fire control hosts and reduces the cost of energy storage integration, but also improves the space utilization of the system, thereby increasing energy density. In addition, 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.

[0052] Specifically, the composite fire detection module in this embodiment integrates a variety of fire detection technologies and can detect early signs of fire in a variety of ways. 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 main control module through the communication module and controls the solenoid valve to extinguish the fire.

[0053] Among them, the smoke detection unit may include a photoelectric smoke detector and a laser smoke detector. The photoelectric smoke detector is used to detect smoke particles in the air using the principle of light scattering; the laser smoke detector is used to detect smoke in the air using laser technology. The temperature detection unit may include a fixed temperature detector and a differential temperature detector. The fixed temperature detector is used to trigger an alarm at a specific temperature and is suitable for detecting high temperature fires; the differential temperature detector is used to detect rapid changes in ambient temperature and is suitable for situations where the fire spreads rapidly.

[0054] In a specific embodiment, multiple detection units can be integrated to realize multi-sensor fusion technology to improve the accuracy and response speed of fire detection. Artificial intelligence algorithms can be used to analyze detection data to identify early signs of fire and achieve faster response. 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 this embodiment integrates multiple detection units, which can detect fires from multiple dimensions and improve the accuracy of detection. The application of multi-sensor fusion technology and artificial intelligence algorithms enables the system to identify fires and respond more quickly. Wireless communication technology reduces the workload of wiring and maintenance, and reduces the maintenance cost of the system. By timely and accurately detecting fires and controlling the fire extinguishing system, the safety of the entire energy storage system is improved.

Each slave control device is connected to the master control device respectively and is responsible for monitoring and managing the fire safety of its corresponding battery pack. The slave control device communicates 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 transmission of data to ensure the response speed and control efficiency of the system. In addition, more advanced serial communication protocols, such as CANopen or Modbus, can also be used to improve the reliability and real-time performance of communication.

[0058] In addition, in actual use, encryption and authentication mechanisms can be integrated into the communication protocol to prevent unauthorized access and data tampering, and enhance the security of the system. Remote monitoring and diagnostic functions can be achieved through the Internet or wireless networks, allowing managers to monitor the status of the fire management system from any location. Using the data collected by the slave control device, the master control device can also use machine learning algorithms to predict faults and monitor health status.

[0059] In this embodiment, through the serial communication protocol bus interface, the master control device can quickly receive data from the slave control device, thereby improving the response speed of the entire fire management system; advanced communication protocols and network security measures are adopted to enhance the reliability of data transmission and the security of the system; the remote monitoring and diagnosis function enables maintenance personnel to remotely identify and solve problems, reducing the need for on-site inspections and improving maintenance efficiency; the modular slave control device and master control device design allows slave control devices to be easily added or removed as needed, thereby improving the flexibility and scalability of the system.

[0060] Alternatively, if Figure 3 As shown, in some embodiments, the fire management system further includes a plurality of battery packs, each battery pack being 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. The slave control device is responsible for monitoring the status of the battery pack, such as temperature, voltage, etc., and initiating corresponding fire protection measures when an abnormality is detected. Wireless communication technology is used between the slave control device and the battery pack to reduce the wiring between the slave control device and the battery pack and improve the flexibility and scalability of the system. With the integrated intelligent BMS, the slave control device can monitor the battery status more accurately and achieve battery health management and optimization.

[0067] To facilitate understanding of the fire management system provided by this embodiment, refer to Figure 4 , Figure 4 A specific implementation method of the fire management system is provided, and the specific process is as follows:

[0068] First, the key parameters in the battery pack are obtained through the slave control device, including carbon monoxide (CO), hydrogen (H2), volatile organic compounds (VOC), smoke concentration parameters, and power parameters and temperature parameters of multiple batteries. These parameters are crucial for evaluating the safety status of the battery pack. The master control module determines the status of the battery based on the acquired parameters, such as judging the battery status through a machine learning algorithm, analyzing whether the battery is in normal working condition, or whether there are safety hazards such as overheating, overcharging, and leakage. If the judgment result shows that the battery status requires fire intervention, the system will send a signal through the digital output (DO) channel of the slave control module to control the fire solenoid valve of a single battery pack (PACK) to open, ensuring that fire extinguishing measures are quickly initiated when a fire risk is detected. At the same time, the system will send the battery status information to the upper-level master control module, which can send the battery status information to the management system or control center to take different fire fighting measures according to the severity of the battery status.
