Description

Technical Field

[0001] This application relates to the technical field of fire control, and particularly to a fire control system, method and device for an energy storage power station. Background Art

[0002] With the rapid development of the new energy industry, as an important link in the grid connection of new energy, the safety issues of energy storage power stations have gradually attracted attention. Energy storage devices such as lithium batteries in energy storage power stations may cause fires during operation due to factors such as overcharging, short circuits, and abnormal ambient temperatures, while traditional fire protection systems are difficult to meet the special requirements of energy storage power stations. Therefore, the research and development of fire alarm and automatic fire extinguishing control systems for energy storage power stations have become the focus of the industry.

[0003] Currently, most of the fire alarm control systems on the market are based on a single detection method, such as smoke or temperature sensing detection, which is easily interfered by environmental factors, has a high false alarm rate, and cannot accurately identify the type of fire. At the same time, the communication methods of traditional systems are relatively single, the data transmission rate is low, it is difficult to achieve multi-device collaborative linkage, and there is a lack of intelligent fire protection logic programming function, which cannot meet the requirements of complex scenarios in energy storage power stations. In addition, some fire alarm systems only have local alarm functions and cannot achieve remote monitoring and data storage, resulting in insufficient accident traceability and prevention capabilities.

[0051] Specific implementation manners

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] With the rapid development of the new energy industry, as an important link in the new energy grid connection, the safety issues of energy storage power stations have gradually attracted attention. Energy storage devices such as lithium batteries in energy storage power stations may cause fires during operation due to factors such as overcharging, short circuits, and abnormal ambient temperatures, while traditional fire protection systems are difficult to meet the special needs of energy storage power stations. Therefore, the research and development of fire alarm and automatic fire extinguishing control systems for energy storage power stations have become the focus of industry attention.

[0054] Currently, most of the fire alarm control systems on the market are based on a single detection method, such as smoke or temperature sensing detection, which is easily interfered by environmental factors, has a high false alarm rate, and cannot accurately identify the type of fire. At the same time, the communication method of traditional systems is relatively single, the data transmission rate is low, it is difficult to achieve multi-device collaborative linkage, and it lacks an intelligent fire protection logic programming function, which cannot meet the requirements of complex scenarios in energy storage power stations. In addition, some fire alarm systems only have local alarm functions and cannot achieve remote monitoring and data storage, resulting in insufficient accident traceability and prevention capabilities.

[0055] Therefore, the present application provides an energy storage power station fire control system, method and device. By communicating with a composite fire detector using the CAN bus, it can collect various data such as smoke, temperature, carbon monoxide, and hydrogen in the energy storage power station in real time, and provide accurate alarm and linkage control in combination with a multi-level fire alarm logic. At the same time, the system adopts a modular design, improves data processing capabilities through a dual-CPU structure, and supports programmable fire protection logic to enhance system flexibility. In addition, the device supports multiple communication interfaces (CAN, MBUS, RS485), can realize remote data upload, remote diagnosis and firmware upgrade, and improve maintenance efficiency. By optimizing power management and automatic main and standby power switching, the stability of the system in extreme environments is improved. The intelligent fire monitoring and fire extinguishing linkage system of the present invention can be widely applied to energy storage power stations to improve fire safety and reduce fire risks.

[0056] Figure 1 It is a schematic diagram of the energy storage power station fire control system module provided by an embodiment of the present application. As Figure 1 shown, the energy storage power station fire control system 100 includes a fire detection module 110, a data processing module 120, an alarm and linkage control module 130, a communication module 140, and a power management module 150. The energy storage power station fire control system 100 is connected to the energy storage power station 10. The data processing module 120 includes a main processor 121 and an auxiliary processor 122. The power management module 150 includes a main power supply 151 and a standby power supply 152.

[0057] It can be understood that the energy storage power station 10 is a modern facility for electric energy storage and dispatching. It is usually composed of energy storage units such as lithium-ion batteries, supercapacitors, flywheel energy storage, or flow batteries, and is equipped with a power management system to achieve functions such as peak shaving and valley filling of the power grid, consumption of renewable energy, and emergency power supply. Energy storage power stations are widely used in new energy power systems, industrial parks, data centers, and grid-side energy storage scenarios.

[0058] Since the energy storage power station contains a large number of high-energy-density batteries and involves complex power conversion and management systems, during long-term operation, fire accidents may be caused by factors such as battery thermal runaway, short circuit, overcharging, and too high ambient temperature. Therefore, establishing an efficient fire detection and prevention system is crucial for ensuring the safe operation of the energy storage power station.

[0059] In the embodiment of the present application, the fire detection module 110 is used to detect fire-related parameters in the energy storage power station 10 to form a detection signal, and transmit the detection signal to the data processing module 120, where the fire-related parameters include smoke concentration, temperature, and combustible gas concentration.

[0060] Specifically, the fire detection module 110 may include multiple types of sensors, such as smoke sensors, temperature sensors, and combustible gas sensors, and these sensors can be distributed at different locations of the energy storage power station 10 to achieve multi-point monitoring and data fusion analysis. When the fire detection module 110 detects abnormal parameters, it immediately generates a detection signal and transmits the detection signal to the data processing module 120 by wired or wireless means.

[0061] It can be understood that the fire detection module 110 can not only operate independently but also be linked with other environmental monitoring systems, such as combined with humidity sensors, wind speed sensors, etc., to further optimize the accuracy of fire detection. In addition, the fire detection module 110 can be configured with different sensitivity thresholds to adapt to different environmental conditions and application requirements.

[0062] In the embodiment of the present application, the data processing module 120 includes a main processor 121 and an auxiliary processor 122. The main processor 121 is used to process the detection signal, detect the detection signal according to the preset logic for fire determination, and the main processor 121 is also used to judge the fire level when it is determined that there is a fire in the energy storage power station. The auxiliary processor 122 is used for data acquisition and system self-check.

[0063] Specifically, after receiving the detection signal, the main processor 121 will comprehensively analyze based on the stored fire determination model or expert rule library, combined with multiple sensor data, to determine whether a fire has occurred, and judge the fire level according to the development of the fire. The fire level can be divided into multiple levels, specifically level one and level two.

[0064] It can be understood that the main processor 121 can adopt artificial intelligence algorithms (such as machine learning or deep learning models) to optimize the fire detection logic, improve the self-adaptability and accuracy of the system. At the same time, the main processor 121 can combine historical data to perform trend analysis on the fire risk and realize the function of early fire warning.

[0065] Specifically, the auxiliary processor 122 is mainly used to collect the data of the fire detection module 110 in real time and perform self-check on the system. The self-check function includes sensor calibration, data transmission link detection, storage status check, etc., to ensure the stable operation of the entire system. When an abnormality is detected, the auxiliary processor 122 can record the error information and notify the main processor 121 to perform corresponding processing.

[0066] It can be understood that the auxiliary processor 122 can also interact with the remote monitoring system, transmit the system health status information to the monitoring center for operation and maintenance personnel to perform remote diagnosis and maintenance. In addition, the auxiliary processor 122 can perform data preprocessing, such as signal filtering, denoising, etc., to improve the data quality.

[0067] In the embodiments of the present application, the alarm and linkage control module 130 is used to perform response operations according to the fire level, and the response operations include triggering on-site audible and visual alarms and delaying the start of the automatic fire extinguishing device.

[0068] Specifically, after detecting a fire and determining the fire level, the alarm and linkage control module 130 performs corresponding response operations. For example, in a low-risk state, the system only sends a remote notification; in a medium-risk state, it triggers on-site audible and visual alarms and starts the local ventilation or cooling system; in a high-risk state, the automatic fire extinguishing device is started with a delay to allow personnel time for intervention or evacuation.

[0069] It can be understood that the alarm and linkage control module 130 can be linked with an external fire protection system or a smart grid system. For example, when the fire reaches a high-risk level, the system can automatically send an alarm message to the fire department, and at the same time control the power output of the energy storage power station to reduce the risk of secondary disasters. In addition, the system can provide a manual intervention interface, enabling operators to manually adjust the alarm level or trigger the fire extinguishing system.

[0070] In the embodiments of the present application, the communication module 140 is used to realize data information interaction between the energy storage power station fire control system 100 and an external monitoring center, other on-site devices, and remote terminals.

[0071] Specifically, the communication module 140 supports multiple communication protocols, including Ethernet, 5G, Wi-Fi, LoRa, etc., to realize real-time data interaction between the energy storage power station fire control system 100 and the remote monitoring center, on-site devices, and mobile terminals.

[0072] It can be understood that the communication module 140 can adopt a dual-channel or redundant communication mechanism to ensure that when the main communication network fails, the system can automatically switch to the standby network to ensure the timely transmission of alarm information. In addition, the communication module 140 supports data encryption and access control to enhance the security of the system.

[0073] In the embodiments of the present application, the power management module 150 is used to provide power for the fire detection module 110, the data processing module 120, the alarm and linkage control module 130, and the communication module 140. Among them, the power management module 150 includes a main power supply 151 and a standby power supply 152, and the power management module 150 is configured to switch to the standby power supply 152 for power supply when the main power supply 151 fails.

[0074] Specifically, the power management module 150 is used to ensure the continuous and stable operation of the entire system. The main power supply 151 usually comes from the power supply system of the energy storage power station, while the backup power supply 152 can be a storage battery, a supercapacitor or a solar power supply unit. In the event of the failure of the main power supply 151, the power management module 150 will automatically switch to the backup power supply 152 to maintain the normal operation of fire detection, data processing, alarm linkage and communication functions.

[0075] It can be understood that the power management module 150 can support intelligent power management strategies, such as dynamically adjusting power distribution according to the system load, or giving priority to ensuring the operation of key modules in the long-term backup power supply mode. In addition, the power management module 150 can monitor the power status in real time and send information such as battery power and charge and discharge status to the remote monitoring center for maintenance and management.

[0076] The energy storage power station fire control system 100 provided by this application realizes the all-round monitoring, accurate determination, intelligent response and efficient emergency handling of the fire risk of the energy storage power station 10 by integrating the fire detection module 110, the data processing module 120, the alarm and linkage control module 130, the communication module 140 and the power management module 150.

[0077] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the modules of the energy storage power station fire control system provided by another embodiment of this application. As Figure 2 shown, the difference between the energy storage power station fire control system 100a and Figure 1 the energy storage power station fire control system 100 shown is that the alarm and linkage control module 130 includes a first response unit 131, a second response unit 132 and a third response unit 133, and the energy storage power station fire control system 100a further includes a human-machine interaction module 160, and the human-machine interaction module 160 includes a housing 161, an operation panel 162 and a display screen 163. The remaining parts in the energy storage power station fire control system 100a are the same as or similar to those in the energy storage power station fire control system 100, and will not be described in detail here.

[0078] In the embodiment of this application, the alarm and linkage control module 130 includes: a first response unit 131, a second response unit 132 and a third response unit 133.

[0079] Specifically, the first response unit 131 further includes an alarm control circuit, an audible and visual alarm device, and a remote alarm interface. The alarm control circuit is configured to receive the fire alarm signal sent by the data processing module 120 and trigger audible and visual alarm devices with different intensities according to the fire level. Specifically, in the case of a first-level fire alarm, the alarm device flashes intermittently and emits a low-frequency beeping sound to alert on-site staff; in the case of a second-level fire alarm, the alarm device flashes at a high frequency and emits a continuous high-decibel alarm to warn of the escalation of the fire situation. In addition, the remote alarm interface is used to upload the fire alarm information to the monitoring center or relevant remote terminals, enabling the operation and maintenance personnel to grasp the fire situation in real time and take necessary measures.

[0080] It can be understood that the alarm control circuit of the first response unit 131 can also work in cooperation with the communication module 140, enabling the energy storage power station fire control system 100a to support the remote alarm notification function of SMS, telephone, or other wireless communication methods to improve the timeliness of fire response.

[0081] In the embodiment of the present application, the first response unit 131 is configured to trigger an audible and visual alarm when the data processing module 120 determines a first-level fire alarm, and is also configured to trigger an audible and visual alarm and a fire extinguishing delay countdown when the data processing module 120 determines a second-level fire alarm.

[0082] Specifically, the first response unit 131 further includes an alarm control circuit, an audible and visual alarm device, and a remote alarm interface. The alarm control circuit is configured to receive the fire alarm signal sent by the data processing module 120 and trigger audible and visual alarm devices with different intensities according to the fire level. Specifically, in the case of a first-level fire alarm, the alarm device flashes intermittently and emits a low-frequency beeping sound to alert on-site staff; in the case of a second-level fire alarm, the alarm device flashes at a high frequency and emits a continuous high-decibel alarm to warn of the escalation of the fire situation. In addition, the remote alarm interface is used to upload the fire alarm information to the monitoring center or relevant remote terminals, enabling the operation and maintenance personnel to grasp the fire situation in real time and take necessary measures.

[0083] It can be understood that the alarm control circuit of the first response unit 131 can also work in cooperation with the communication module 140, enabling the energy storage power station fire control system 100a to support the remote alarm notification function of SMS, telephone, or other wireless communication methods to improve the timeliness of fire response.

[0084] In the embodiment of the present application, the second response unit 132 automatically activates the fire extinguishing device solenoid valve to spray the fire extinguishing agent after the fire extinguishing delay countdown ends, and receives the spraying feedback signal of the gas cylinder pressure switch.

[0085] Specifically, the second response unit 132 further includes a fire extinguishing agent spraying controller, a spraying state detection module, and a feedback signal receiving module. The fire extinguishing agent spraying controller is used to automatically control the opening of the solenoid valve after receiving the signal indicating the end of the fire extinguishing countdown, ensuring that the fire extinguishing agent is released according to the preset spraying strategy. The spraying state detection module is used to monitor the state of the fire extinguishing agent release in real time, such as parameters like spraying pressure and flow rate, and send an alarm signal to the data processing module 120 when the spraying is abnormal. The feedback signal receiving module is used to receive the feedback signal from the pressure switch of the gas storage cylinder and confirm to the data processing module 120 whether the fire extinguishing agent has been successfully sprayed, thereby improving the reliability and safety of the system.

[0086] It can be understood that the fire extinguishing agent spraying controller of the second response unit 132 can adjust the fire extinguishing agent release amount according to the fire level. For example, in the case of a second-level fire alarm, local spraying is triggered, while in a higher-level fire alarm (such as a third-level fire alarm), full-area spraying is triggered to optimize the fire extinguishing effect and reduce the waste of the fire extinguishing agent.

[0087] In the embodiment of the present application, the second response unit 132 automatically activates the solenoid valve of the fire extinguishing device after the end of the fire extinguishing delay countdown to spray the fire extinguishing agent, and receives the spraying feedback signal from the pressure switch of the gas storage cylinder.

[0088] In the embodiment of the present application, the third response unit 133 provides a manual start button interface and a mechanical emergency operation channel. The mechanical emergency channel directly drives the fire extinguishing agent container valve through a physical handle.

[0089] Specifically, the third response unit 133 further includes a manual start button, a mechanical emergency operation channel, and a remote control interface. The manual start button is used to allow on-site personnel to manually activate the fire extinguishing device when the automatic fire extinguishing system fails or manual intervention is required. The mechanical emergency operation channel directly drives the fire extinguishing agent container valve through a physical handle to ensure that in extreme cases, even if the electronic system fails, the fire extinguishing agent can still be released by physical means. The remote control interface allows the monitoring center or an authorized remote terminal to send a manual start instruction to remotely control the activation of the fire extinguishing device.

[0090] It can be understood that the remote control interface of the third response unit 133 can be combined with the communication module 140 to realize the real-time monitoring and manual intervention of the fire extinguishing system by the remote monitoring center, so as to provide additional safety protection when on-site personnel cannot operate in time.

[0091] In an embodiment of the present application, the alarm and linkage control module 130 is further used to determine whether both the smoke concentration and temperature of the energy storage power station 10 are higher than the preset thresholds. If both the smoke concentration and temperature of the energy storage power station 10 are higher than the preset thresholds, a second-level fire alarm is triggered. If either the smoke concentration or temperature of the energy storage power station 10 is higher than the preset threshold, a first-level fire alarm is triggered.

[0092] Specifically, when the alarm and linkage control module 130 determines the concentration of combustible gas, it further combines the smoke concentration and temperature data to improve the accuracy of fire warning. For example, when the concentration of combustible gas is higher than the first preset threshold but does not exceed the second preset threshold, if the smoke concentration and temperature are also close to the warning value, measures can be taken in advance, such as increasing the operating power of the fan or sending a remote warning notice, to reduce the fire risk. In addition, if the concentration of combustible gas is higher than the second preset threshold, it will not only trigger the fire extinguishing delay countdown and the fan shutdown operation, but also send an emergency fire alarm message to the remote monitoring center to ensure that the operation and maintenance personnel can intervene in time.

[0093] It can be understood that the fire determination mechanism of the alarm and linkage control module 130 adopts multi-parameter fusion analysis to avoid false alarms or missed alarms caused by abnormal single sensors. For example, when the smoke concentration, temperature, and combustible gas concentration all exceed the standard, a high-level fire alarm can be triggered preferentially; if only one parameter is abnormal, the system can make a dynamic judgment in combination with the historical data trend to reduce the possibility of false alarms and improve the intelligence level of the system.

[0094] In an embodiment of the present application, the alarm and linkage control module 130 is further configured to obtain the concentration of combustible gas in the energy storage power station 10. Determine whether the concentration of combustible gas is higher than the first preset threshold. If the concentration of combustible gas is higher than the first preset threshold, then determine whether the concentration of combustible gas is higher than the second preset threshold. If the concentration of combustible gas is higher than the first preset threshold and lower than the second preset threshold, trigger an audible and visual alarm and start the fan. If the concentration of combustible gas is higher than the second preset threshold, trigger an audible and visual alarm and the fire extinguishing delay countdown, and turn off the fan.

[0095] Specifically, when the alarm and linkage control module 130 determines the concentration of combustible gas, it further combines the smoke concentration and temperature data to improve the accuracy of fire warning. For example, when the concentration of combustible gas is higher than the first preset threshold but does not exceed the second preset threshold, if the smoke concentration and temperature are also close to the warning value, measures can be taken in advance, such as increasing the operating power of the fan or sending a remote warning notice, to reduce the fire risk. In addition, if the concentration of combustible gas is higher than the second preset threshold, it will not only trigger the fire extinguishing delay countdown and the fan shutdown operation, but also send an emergency fire alarm message to the remote monitoring center to ensure that the operation and maintenance personnel can intervene in time.

[0096] It can be understood that the fire determination mechanism of the alarm and linkage control module 130 adopts multi-parameter fusion analysis to avoid false alarms or missed alarms caused by abnormal single sensors. For example, when the smoke concentration, temperature, and combustible gas concentration all exceed the standard, a high-level fire alarm can be triggered preferentially; if only one parameter is abnormal, the system can make a dynamic judgment in combination with the historical data trend to reduce the possibility of false alarms and improve the intelligence level of the system.

[0097] In an embodiment of the present application, the alarm and linkage control module 130 is further configured to continuously collect fire condition data during the fire extinguishing delay countdown and transmit it to the alarm and linkage control module 130. If the fire-related parameters are lower than the preset threshold, the countdown is cancelled and the alarm and linkage control module is controlled to cancel the fire extinguishing operation. If the fire-related parameters are higher than the preset threshold, a fire extinguishing start instruction is generated.

[0098] Specifically, during the fire extinguishing delay countdown, the alarm and linkage control module 130 continuously monitors the fire-related parameters and performs real-time analysis through the data processing module 120. If the fire-related parameters drop within the safe range, the system will automatically cancel the fire extinguishing instruction and reset to the normal monitoring state to avoid unnecessary fire extinguishing operations. In addition, if the fire condition worsens during the countdown, such as the temperature or the concentration of combustible gas continues to rise, the system will skip the remaining countdown and directly trigger the fire extinguishing device to ensure a quick response.

[0099] It can be understood that the adaptive adjustment of the fire extinguishing delay countdown mechanism can improve the flexibility of fire response. For example, in the initial stage of a fire, if it is detected that the fire condition shows a weakening trend, the system can appropriately extend the countdown to observe the fire trend and avoid prematurely triggering the fire extinguishing device; while in the case of a worsening fire, the countdown is shortened or the fire extinguishing is triggered immediately to minimize losses.

[0100] In an embodiment of the present application, the main processor 121 and the auxiliary processor 122 are connected through a dual-channel communication bus. The main processor 121 is configured to execute a preset fire alarm logic operation to generate multi-level linkage instructions. The auxiliary processor 122 is configured to perform periodic system self-checks to detect whether there are faults in the energy storage power station fire control system and feedback the fault status to the main processor. The faults include sensor disconnection, communication interruption, and power supply abnormality faults.

[0101] Specifically, the dual-channel communication bus between the main processor 121 and the auxiliary processor 122 supports data redundancy and an automatic fault switching mechanism. When the main processor 121 executes the fire alarm logic, it can simultaneously send key status data to the auxiliary processor 122. During the system self-check process, if the auxiliary processor 122 detects an abnormality in the main processor 121 (such as a decrease in processing speed, data error, etc.), it can take over part of the alarm and linkage control functions to ensure the stable operation of the system. In addition, if the dual-channel communication bus fails, the system can switch to the single-channel mode and still maintain the core fire monitoring and alarm functions.

[0102] It can be understood that the way the main processor 121 and the auxiliary processor 122 work together improves the reliability and fault tolerance of the energy storage power station fire control system. Through regular self-checks, the auxiliary processor 122 can detect and report system faults in a timely manner, such as sensor wire breaks, communication interruptions, and power anomalies, enabling maintenance personnel to intervene as early as possible, reducing the monitoring blind spots caused by equipment failures, and improving the safety of the energy storage power station.

[0103] In the embodiment of the present application, the system further includes: a human-machine interaction module 160, which is used to display the fire status of the energy storage power station, sensor data, and equipment operation information in real time, and provide an operation instruction input interface.

[0104] In the embodiment of the present application, the human-machine interaction module 160 includes: a housing 161, which is provided with a honeycomb-shaped sound hole array and exposed wiring terminals. An operation panel 162, which includes a plurality of buttons for controlling the start and stop of fire extinguishing. The operation panel is also provided with a button operation locking logic to prevent accidental triggering of the fire extinguishing instruction. A display screen 163, which is used to display the smoke concentration, temperature, gas concentration curve, and equipment topology diagram of the energy storage power station.

[0105] Specifically, in the embodiment of the present application, the housing 161 of the human-machine interaction module 160 is made of high-temperature resistant and corrosion-resistant materials to ensure stable operation in high-temperature, high-humidity, and harsh environments. The honeycomb-shaped sound hole array is designed to optimize sound propagation, enabling the sound and light alarm signal to be quickly transmitted to the surrounding environment in case of an emergency, improving the effectiveness of the fire alarm. In addition, the exposed wiring terminals facilitate maintenance personnel to perform rapid wiring and equipment replacement, enhancing the maintainability and reliability of the system.

[0106] In the embodiment of the present application, the buttons on the operation panel 162 adopt a physical anti-misoperation design, and the button operation locking logic ensures the safety of the fire extinguishing instruction. For example, when the button is not double-confirmed or long-pressed, the system will not execute the fire extinguishing operation to prevent potential safety hazards caused by misoperation. In addition, the operation panel also has optimized environmental adaptability, and the buttons are designed to be shock-resistant, waterproof, and dust-proof, enabling it to still work stably in complex industrial environments.

[0107] In the embodiment of the present application, the display screen 163 adopts a high-definition industrial-grade liquid crystal screen, which has the characteristics of high brightness and wide viewing angle, ensuring that the key parameters of the energy storage power station can still be clearly displayed in strong light environments. The smoke concentration, temperature, and combustible gas concentration curves can be updated in real time and scrolled, and the operation and maintenance personnel can intuitively monitor the development trend of the fire and quickly locate the abnormal area in combination with the equipment topology diagram, thereby improving the emergency response efficiency. In addition, the display screen supports the remote access function and can be connected to the monitoring center through the network to achieve data synchronization and remote diagnosis.

[0108] In the embodiment of the present application, the display screen 163 is equipped with an 800×480 color liquid crystal screen, which can display key data such as the fire status, smoke / temperature / gas concentration curves in real time. The operation panel 162 provides 24 buttons and LED indicators at the same time, supporting functions such as fire extinguishing start, mode switching, and audible and visual alarms. The operation interface is intuitive, enabling users to quickly obtain information, improving the operation convenience and safety. In addition, the button operation locking function prevents misoperations, further enhancing the stability of the system.

[0109] It can be understood that the human-machine interaction module 160 not only provides an intuitive operation interface, but also integrates intelligent interaction functions such as voice prompts, remote control, and data log storage. The system can analyze the fire trend based on historical data and provide early warning information in combination with artificial intelligence algorithms to assist the operation and maintenance personnel in making decisions. In addition, the human-machine interaction module 160 can also be connected to other security systems such as video surveillance and environmental monitoring systems to achieve multi-dimensional security protection and improve the overall security and management efficiency of the energy storage power station.

[0110] Please refer to Figures 3 to 6 , Figure 3 which is a schematic connection diagram of the main processor provided by an embodiment of the present application. Figure 4 which is a schematic connection diagram of the main processor of the energy storage power station fire control system provided by an embodiment of the present application. Figure 5 which is a schematic connection diagram of the auxiliary processor of the energy storage power station fire control system provided by an embodiment of the present application. Figure 6 which is a schematic connection diagram of the alarm lamp of the energy storage power station fire control system provided by an embodiment of the present application.

[0111] In this embodiment, the specific model of the main processor 121 is R7FA6M3AH3CFC. As Figure 3 shown, the main processor 121 is respectively connected to the auxiliary processor 122 and the alarm lamp to realize the real-time transmission of data and alarm signals. Figure 4 shows that in the energy storage power station fire control system, the main processor 121, as the core control unit, is connected to the fire detection device, temperature and humidity sensor, and gas detection module through the CAN bus, RS485, and MBUS interfaces, so as to obtain various detection signals in the energy storage power station.

[0112] The main processor 121 is used to process the detection signals, determine whether there is a fire according to the preset logic for the detection signals, and classify the fire level when it is determined that there is a fire in the energy storage power station, ensuring that the alarm signal and the linkage operation can accurately correspond to the severity of the fire risk. As Figure 4 shown, after comprehensive analysis, the main processor 121 sends the determination result to the auxiliary processor 122 and the alarm lamp so that the system can further take corresponding measures.

[0113] AsFigure 5 As shown, the auxiliary processor 122 mainly undertakes the functions of data acquisition and system self-check. It periodically collects data information from various sensors and detects the overall operating state of the system, including the sensor connection state, data transmission integrity, and power supply state, etc. If an abnormal situation is detected, the auxiliary processor 122 will immediately feedback the fault information to the main processor 121 to promptly activate the fault protection mechanism or switch to the standby working mode, ensuring the stability and reliability of the fire monitoring system.

[0114] In addition, as Figure 6 shown, the alarm lamp, as the visual alarm output device of the system, provides an intuitive optical signal warning during a fire under the control of the main processor 121. The state of the alarm lamp (such as the flashing frequency, color, etc.) will be dynamically adjusted according to the different fire levels, thereby helping on-site personnel quickly judge the severity of the fire and take corresponding emergency measures.

[0115] It can be understood that the two-way communication between the main processor 121 and the auxiliary processor 122 and the connection to the alarm lamp constitute the core part of the energy storage power station fire control system in this embodiment. The main processor 121 makes precise judgments on the detection signals according to the preset logic and further classifies them when a fire is judged to exist; at the same time, the auxiliary processor 122 ensures real-time data acquisition and system self-check, provides redundant protection for the system, and further improves the overall stability and safety of the fire alarm and linkage control system.

[0116] In this embodiment, the energy storage power station fire control system 100 has the function of recording fire alarm historical events and information. This function realizes the automatic recording and classified storage of all fire alarm events through the built-in memory and data management system, including the alarm time, alarm source, alarm type, response operation, and processing result.

[0117] Specifically, the energy storage power station fire control system 100 adopts FLASH storage technology to ensure that data is not lost in the case of power failure. The historical records can store no less than 10,000 alarm messages and support querying according to time, alarm type, and device address. The operation and maintenance personnel can access the historical data through the liquid crystal display screen or the remote communication interface (such as CAN bus, RS485) to trace and analyze the causes and trends of fires and optimize the fire protection strategy. In addition, this function supports USB or network export, which is convenient for management personnel to regularly back up data and perform data analysis through the supporting software. For example, the system can combine historical data for trend prediction, discover potential fire hazards in advance, and improve the overall fire prevention and control ability.

[0118] It is understandable that this embodiment provides a communication solution for fire detection devices based on the CAN bus to ensure stable and efficient data exchange between the fire detection devices and the energy storage power station fire control system 100.

[0119] The energy storage power station fire control system 100 communicates in real time with the composite fire detection device (including carbon monoxide, smoke and temperature composite detection device) through the CAN bus. This communication method has the advantages of strong anti-interference ability, stable data transmission, and support for multi-device parallel connection.

[0120] The energy storage power station fire control system 100 adopts the CAN2.0B protocol, supports a communication rate of up to 1 Mbps, and ensures the integrity and accuracy of data through CRC check. Each fire detection device has a unique address, and the energy storage power station fire control system 100 can interact with it through broadcast or point-to-point communication methods.

[0121] When a certain detector detects a fire signal, it will immediately send an alarm message to the control device through the CAN bus. After receiving the first fire signal, the control device starts the alarm, and after confirming the second fire signal, it executes linkage control, including starting the fire extinguishing system, notifying the duty personnel, etc. In addition, this solution also supports remote configuration and status query of the detector. The operation and maintenance personnel can adjust parameters such as the sensitivity and sampling interval of the detector through the control device or remote management software, and obtain the device operation status, such as sensor failure, power status, etc.
