[0024] DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] With the rapid development of the new energy industry, energy storage power stations, as an important part of new energy grid connection, have gradually received attention for their safety issues. During operation, lithium batteries and other energy storage equipment in energy storage power stations may cause fires due to factors such as overcharging, short circuits, and abnormal ambient temperature, and 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 has become the focus of industry attention.

[0027] At present, most fire alarm control systems on the market are based on a single detection method, such as smoke or temperature 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 the traditional system is relatively simple, the data transmission rate is low, it is difficult to achieve multi-device coordination and linkage, and lacks intelligent fire logic programming functions, which cannot meet the needs 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 tracing and prevention capabilities.

[0028] Therefore, the present application provides a fire control system, method and device for an energy storage power station, which uses a CAN bus to communicate with a composite fire detector, can collect various data such as smoke, temperature, carbon monoxide, hydrogen, etc. in the energy storage station in real time, and combines multi-level fire alarm logic to provide accurate alarm and linkage control. At the same time, the system adopts a modular design, improves data processing capabilities through a dual CPU structure, and supports programmable fire logic to enhance system flexibility. In addition, the device supports a variety of 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 switching between main and standby power, 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 used in energy storage power stations to improve fire safety and reduce fire risks.

[0029] Figure 1 Schematic diagram of the fire control system module of the energy storage power station provided in the embodiment of the present application. Figure 1As 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, and the power management module 150 includes a main power supply 151 and a backup power supply 152.

[0030] It is understandable that the energy storage power station 10 is a modern facility for electric energy storage and dispatching, which 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 grid peak shaving, renewable energy consumption, and emergency power supply. Energy storage power stations are widely used in scenarios such as new energy power systems, industrial parks, data centers, and grid-side energy storage.

[0031] Since energy storage power stations contain a large number of high-energy-density batteries and involve complex power conversion and management systems, fire accidents may occur during long-term operation due to factors such as battery thermal runaway, short circuit, overcharging, and excessive ambient temperature. Therefore, establishing an efficient fire detection and prevention system is crucial to ensure the safe operation of energy storage power stations.

[0032] In an 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, wherein the fire-related parameters include smoke concentration, temperature, and combustible gas concentration.

[0033] 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 may 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 an abnormal parameter, it immediately generates a detection signal and transmits the detection signal to the data processing module 120 via wired or wireless means.

[0034] It is understandable that the fire detection module 110 can not only operate independently, but also be linked with other environmental monitoring systems, such as combining 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.

[0035] 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 and perform fire determination according to the preset logic detection signal. The main processor 121 is also used to determine the fire level when determining that there is a fire in the energy storage power station. The auxiliary processor 122 is used to perform data collection and system self-test.

[0036] Specifically, after receiving the detection signal, the main processor 121 will perform a comprehensive analysis based on the stored fire determination model or expert rule base and multiple sensor data to determine whether a fire has occurred and determine the fire level according to the fire development. The fire level can be divided into multiple levels, specifically level one and level two.

[0037] It is understandable that the main processor 121 can use artificial intelligence algorithms (such as machine learning or deep learning models) to optimize the fire detection logic and improve the system's adaptability and accuracy. At the same time, the main processor 121 can combine historical data to perform trend analysis on fire risks and implement early warning functions for fires.

[0038] Specifically, the auxiliary processor 122 is mainly used to collect data from 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.

[0039] It is understandable that the auxiliary processor 122 can also interact with the remote monitoring system to transmit system health status information to the monitoring center so that operation and maintenance personnel can perform remote diagnosis and maintenance. In addition, the auxiliary processor 122 can perform data preprocessing, such as signal filtering, denoising, etc., to improve data quality.

[0040] In the embodiment 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 sound and light alarms and delaying the start of automatic fire extinguishing devices.

[0041] 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, an on-site sound and light alarm is triggered, and a local ventilation or cooling system is started; in a high-risk state, the automatic fire extinguishing device will be delayed to allow personnel time to intervene or evacuate.

[0042] It is understandable 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 a fire reaches a high-risk level, the system can automatically send an alarm message to the fire department and 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 so that the operator can manually adjust the alarm level or trigger the fire extinguishing system.

[0043] In the embodiment 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 the external monitoring center, other on-site equipment and remote terminals.

[0044] 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 equipment, and mobile terminals.

[0045] It is understandable 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 backup network to ensure timely transmission of alarm information. In addition, the communication module 140 supports data encryption and access control to enhance the security of the system.

[0046] In the embodiment 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. The power management module 150 includes a main power supply 151 and a backup power supply 152, and the power management module 150 is configured to switch to the backup power supply 152 for power supply when the main power supply 151 fails.

[0047] 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, and the backup power supply 152 can be a battery, a super capacitor or a solar power supply unit. In the event of 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.

[0048] It is understandable that the power management module 150 can support intelligent power management strategies, such as dynamically adjusting power distribution according to system load, or giving priority to the operation of key modules in long-term standby 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, charge and discharge status, etc. to the remote monitoring center for maintenance and management.

[0049] The energy storage power station fire control system 100 provided in the present application realizes 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.

[0050] Please also read Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a fire control system module for an energy storage power station provided by another embodiment of the present application. Figure 2 The energy storage power station fire control system 100a shown is Figure 1 The difference of 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 also includes a human-computer interaction module 160, and the human-computer interaction module 160 includes a housing 161, an operation panel 162 and a display screen 163. The remaining parts of the energy storage power station fire control system 100a are the same or similar to the energy storage power station fire control system 100, and are not repeated here.

[0051] In the embodiment of the present 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 .

[0052] 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 used to receive the fire alarm signal sent by the data processing module 120, and trigger the audible and visual alarm device of 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 beep to alert the 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. In addition, the remote alarm interface is used to upload the fire alarm information to the monitoring center or related remote terminals, so that the operation and maintenance personnel can grasp the fire situation in real time and take necessary measures.

[0053] It is understandable that the alarm control circuit of the first response unit 131 can also work in conjunction with the communication module 140, so that the energy storage power station fire control system 100a can support remote alarm notification functions via text messages, phone calls or other wireless communication methods to improve the timeliness of fire response.

[0054] In an embodiment of the present application, the first response unit 131 is used to trigger an audible and visual alarm when the data processing module 120 determines it to be a level one fire alarm, and is also used to trigger an audible and visual alarm and a fire extinguishing delay countdown when the data processing module 120 determines it to be a level two fire alarm.

[0055] 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 used to receive the fire alarm signal sent by the data processing module 120, and trigger the audible and visual alarm device of 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 beep to alert the 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. In addition, the remote alarm interface is used to upload the fire alarm information to the monitoring center or related remote terminals, so that the operation and maintenance personnel can grasp the fire situation in real time and take necessary measures.

[0056] It is understandable that the alarm control circuit of the first response unit 131 can also work in conjunction with the communication module 140, so that the energy storage power station fire control system 100a can support remote alarm notification functions via text messages, phone calls or other wireless communication methods to improve the timeliness of fire response.

[0057] In the embodiment of the present application, the second response unit 132 automatically starts the solenoid valve of the fire extinguishing device after the fire extinguishing delay countdown ends to spray the fire extinguishing agent, and receives the spraying feedback signal of the gas cylinder pressure switch.

[0058] 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 fire extinguishing countdown end signal to ensure 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 spraying pressure, flow rate and other parameters, 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 of the gas cylinder pressure switch and confirm to the data processing module 120 whether the fire extinguishing agent is successfully sprayed, thereby improving the reliability and safety of the system.

[0059] It is understandable that the fire extinguishing agent spraying controller of the second response unit 132 can adjust the amount of fire extinguishing agent released according to the fire level, for example, triggering local spraying in case of a second-level fire alarm, and triggering full-area spraying in case of a higher-level fire alarm (such as a third-level fire alarm), so as to optimize the fire extinguishing effect and reduce the waste of fire extinguishing agent.

[0060] In the embodiment of the present application, the second response unit 132 automatically starts the solenoid valve of the fire extinguishing device after the fire extinguishing delay countdown ends to spray the fire extinguishing agent, and receives the spraying feedback signal of the gas cylinder pressure switch.

[0061] In the embodiment of the present application, the third response unit 133 provides a manual start button interface and a mechanical emergency operation channel, and the mechanical emergency channel directly drives the fire extinguishing agent container valve through a physical handle.

[0062] 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 requires manual intervention. 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 command to remotely control the start of the fire extinguishing device.

[0063] It is understandable that the remote control interface of the third response unit 133 can be combined with the communication module 140 to enable 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 are unable to operate in time.

[0064] In one embodiment of the present application, the alarm and linkage control module 130 is also used to determine whether the smoke concentration and temperature of the energy storage power station 10 are both higher than the preset threshold. If the smoke concentration and temperature of the energy storage power station 10 are both higher than the preset threshold, a second-level fire alarm is triggered. If 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.

[0065] Specifically, the alarm and linkage control module 130 further combines the smoke concentration and temperature data when judging the concentration of combustible gas 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 fan operating power or sending a remote warning notification to reduce the risk of fire. 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 fan shutdown operation, but also send emergency fire alarm information to the remote monitoring center to ensure that the operation and maintenance personnel can intervene in time.

[0066] It is understandable 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 a single sensor abnormality. For example, when the smoke density, temperature and combustible gas concentration exceed the standard at the same time, a high-level fire alarm can be triggered first; if only one parameter is abnormal, the system can make a dynamic judgment based on the historical data trend to reduce the possibility of false alarms and improve the intelligence level of the system.

[0067] In one embodiment of the present application, the alarm and linkage control module 130 is also used to obtain the combustible gas concentration of the energy storage power station 10. Determine whether the combustible gas concentration is higher than a first preset threshold. If the combustible gas concentration is higher than the first preset threshold, determine whether the combustible gas concentration is higher than a second preset threshold. If the combustible gas concentration 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 combustible gas concentration is higher than the second preset threshold, trigger an audible and visual alarm and a fire extinguishing delay countdown, and turn off the fan.

[0068] Specifically, the alarm and linkage control module 130 further combines the smoke concentration and temperature data when judging the concentration of combustible gas 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 fan operating power or sending a remote warning notification to reduce the risk of fire. 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 fan shutdown operation, but also send emergency fire alarm information to the remote monitoring center to ensure that the operation and maintenance personnel can intervene in time.

[0069] It is understandable 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 a single sensor abnormality. For example, when the smoke density, temperature and combustible gas concentration exceed the standard at the same time, a high-level fire alarm can be triggered first; if only one parameter is abnormal, the system can make a dynamic judgment based on the historical data trend to reduce the possibility of false alarms and improve the intelligence level of the system.

[0070] In one embodiment of the present application, the alarm and linkage control module 130 is also used to continuously collect fire 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 canceled 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.

[0071] Specifically, during the fire extinguishing delay countdown, the alarm and linkage control module 130 continuously monitors fire-related parameters and performs real-time analysis through the data processing module 120. If the fire-related parameters drop to a safe range, the system will automatically cancel the fire extinguishing command and reset to the normal monitoring state to avoid unnecessary fire extinguishing operations. In addition, if the fire intensifies 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.

[0072] It is understandable that the adaptive adjustment of the fire extinguishing delay countdown mechanism can improve the flexibility of fire response. For example, in the early stage of a fire, if the fire is detected to be weakening, the system can appropriately extend the countdown to observe the change of the fire and avoid triggering the fire extinguishing device too early; if the fire intensifies, the countdown will be shortened or the fire extinguishing device will be triggered immediately to minimize the loss.

[0073] In the embodiment of the present application, the main processor 121 and the auxiliary processor 122 are connected via a two-way communication bus. The main processor 121 is used to execute the preset fire alarm logic operation and generate multi-level linkage instructions. The auxiliary processor 122 is used to perform periodic system self-checks to detect whether there is a fault in the energy storage power station fire control system, and feedback the fault status to the main processor. The fault includes sensor disconnection, communication interruption and power supply abnormality.

[0074] Specifically, the dual-channel communication bus between the main processor 121 and the auxiliary processor 122 supports data redundancy and automatic fault switching mechanisms. When executing the fire alarm logic, the main processor 121 can simultaneously send key status data to the auxiliary processor 122. During the system self-check process, if the auxiliary processor 122 finds that the main processor 121 is abnormal (such as a decrease in processing speed, data errors, etc.), it can take over some alarm and linkage control functions to ensure stable operation of the system. In addition, if the dual-channel communication bus fails, the system can switch to a single-channel mode and still maintain the core fire monitoring and alarm functions.

[0075] It is understandable that the main processor 121 and the auxiliary processor 122 work in coordination to improve the reliability and fault tolerance of the energy storage power station fire control system. Through regular self-checking, the auxiliary processor 122 can promptly detect and report system faults, such as sensor disconnection, communication interruption, and power supply abnormality, so that maintenance personnel can intervene as early as possible, reduce monitoring blind spots caused by equipment failures, and improve the safety of energy storage power stations.

[0076] In the embodiment of the present application, the system also includes: a human-computer 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.

[0077] In the embodiment of the present application, the human-machine interaction module 160 includes: a housing 161, which is provided with a honeycomb sound hole array and an exposed wiring terminal. An operation panel 162, which includes a plurality of buttons, which are used to control the start and stop of fire extinguishing, and the operation panel is also provided with a button operation lock logic to prevent the fire extinguishing command from being triggered by mistake. 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.

[0078] 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 sound hole array is designed to optimize sound propagation, so that the sound and light alarm signals can be quickly transmitted to the surrounding environment in an emergency, thereby improving the effectiveness of the fire alarm. In addition, the exposed terminal blocks facilitate maintenance personnel to quickly carry out wiring and equipment replacement, thereby improving the maintainability and reliability of the system.

[0079] In the embodiment of the present application, the buttons of the operation panel 162 are designed to prevent accidental touches, and the button operation lock logic ensures the safety of the fire extinguishing command. For example, if the button is not double-confirmed or long-pressed, the system will not perform the fire extinguishing operation to prevent safety hazards caused by misoperation. In addition, the operation panel also has environmental adaptability optimization, and the buttons are designed to be shock-resistant, waterproof, and dust-proof, so that it can still work stably in complex industrial environments.

[0080] In the embodiment of the present application, the display screen 163 uses a high-definition industrial-grade LCD screen with high brightness and wide viewing angle to ensure that the key parameters of the energy storage power station can be clearly displayed in a strong light environment. The smoke concentration, temperature and combustible gas concentration curves can be updated in real time. The operation and maintenance personnel can intuitively monitor the development trend of the fire and quickly locate abnormal areas in combination with the equipment topology map, thereby improving the efficiency of emergency response. In addition, the display screen supports remote access function and can be connected to the monitoring center through the network to achieve data synchronization and remote diagnosis.

[0081] In the embodiment of the present application, the display screen 163 is equipped with an 800×480 color LCD screen, which displays key data such as fire status, smoke / temperature / gas concentration curves in real time. The operation panel 162 also provides 24 buttons and LED indicators, supporting functions such as fire extinguishing start, mode switching, and sound and light alarms. The operation interface is intuitive, and users can quickly obtain information, improving the convenience and safety of operation. In addition, the key operation lock function prevents misoperation and further improves the stability of the system.

[0082] It is understandable that the human-computer interaction module 160 not only provides an intuitive operating interface, but also integrates intelligent interactive functions such as voice prompts, remote control and data log storage. The system can analyze fire trends based on historical data and provide early warning information in combination with artificial intelligence algorithms to assist operation and maintenance personnel in making decisions. In addition, the human-computer 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 safety and management efficiency of energy storage power stations.

Figure 4This is a schematic diagram of the connection of the main processor of the energy storage power station fire control system provided in one embodiment of the present application. Figure 5 This is a schematic diagram of the connection of an auxiliary processor of an energy storage power station fire control system provided in one embodiment of the present application. Figure 6 This is a schematic diagram of the alarm light connection of the energy storage power station fire control system provided in one embodiment of the present application.

[0084] In this embodiment, the specific model of the main processor 121 is R7FA6M3AH3CFC. Figure 3 As shown, the main processor 121 is connected to the auxiliary processor 122 and the alarm light respectively to achieve real-time transmission of data and alarm signals. Figure 4 It shows that in the fire control system of the energy storage power station, the main processor 121 serves as the core control unit and is connected to the fire detection equipment, temperature and humidity sensors and gas detection modules through the CAN bus, RS485 and MBUS interfaces, so as to obtain various detection signals in the energy storage power station.

[0085] The main processor 121 is used to process the detection signal, perform fire determination on the detection signal according to the preset logic, and classify the fire level when it is determined that there is a fire in the energy storage power station, so as to ensure that the alarm signal and linkage operation can accurately correspond to the severity of the fire risk. Figure 4 As shown in , after comprehensive analysis, the main processor 121 sends the determination result to the auxiliary processor 122 and the warning light so that the system can further take corresponding measures.

[0086] like Figure 5 As shown, the auxiliary processor 122 is mainly responsible for data collection and system self-checking functions. It periodically collects data information from each sensor and detects the overall operating status of the system, including sensor connection status, data transmission integrity, and power supply status. If an abnormality is detected, the auxiliary processor 122 will immediately feedback the fault information to the main processor 121 so as to promptly start the fault protection mechanism or switch to the backup working mode to ensure the stability and reliability of the fire monitoring system.

[0087] In addition, if Figure 6 As shown, the alarm light is used as a visual alarm output device of the system, and provides an intuitive light signal warning when a fire occurs through the control of the main processor 121. The state of the alarm light (such as flashing frequency, color, etc.) will be dynamically adjusted according to the different fire levels, thereby helping on-site personnel to quickly determine the severity of the fire and take corresponding emergency measures.

[0088] It can be understood that the two-way communication between the main processor 121 and the auxiliary processor 122 and the connection with the alarm light constitute the core part of the fire control system of the energy storage power station in this embodiment. The main processor 121 accurately judges the detection signal according to the preset logic, and further classifies it when it is determined that a fire exists; at the same time, the auxiliary processor 122 ensures real-time data collection and system self-checking, provides redundant protection for the system, and further improves the overall stability and safety of the fire alarm and linkage control system.

[0089] In this embodiment, the energy storage power station fire control system 100 has a fire alarm history event and information recording function. This function uses a built-in memory and data management system to automatically record and classify all fire alarm events, including alarm time, alarm source, alarm type, response operation and processing results.

[0090] Specifically, the energy storage power station fire control system 100 adopts FLASH storage technology to ensure that data is not lost in the event of a power outage. The historical records can store no less than 10,000 alarm messages, and support inquiries by time, alarm type, and device address. Operation and maintenance personnel can access historical data through an LCD display or a remote communication interface (such as CAN bus, RS485) to retrospectively analyze the causes and trends of fires and optimize firefighting strategies. In addition, this function supports USB or network export, which is convenient for managers to back up data regularly and perform data analysis through supporting software. For example, the system can combine historical data for trend prediction, discover possible fire hazards in advance, and improve overall fire prevention and control capabilities.

[0091] It can be understood that this embodiment provides a fire detection device communication solution based on the CAN bus, which ensures stable and efficient data exchange between the fire detection device and the energy storage power station fire control system 100.

[0092] The energy storage power station fire control system 100 communicates in real time with the composite fire detection equipment (including carbon monoxide, smoke and temperature composite detection devices) through the CAN bus. This communication method has the advantages of strong anti-interference ability, stable data transmission, and support for multiple devices in parallel.

[0093] The energy storage power station fire control system 100 adopts the CAN2.0B protocol, supports a communication rate of up to 1Mbps, and ensures the integrity and accuracy of the data through CRC verification. 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.

[0094] When a detector detects a fire signal, it will immediately send an alarm message to the control device through the CAN bus. The control device will activate the alarm after receiving the first fire signal, and perform linkage control after confirming the second fire signal, including starting the fire extinguishing system and notifying the on-duty personnel. In addition, the solution also supports remote configuration and status query of detectors. Operation and maintenance personnel can adjust the sensitivity, sampling interval and other parameters of the detector through the control device or remote management software, and obtain the operating status of the equipment, such as sensor failure, power status, etc.
