Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0021] In order to solve the technical problem that the existing technology has relatively simple and imprecise warning threshold settings, which leads to inaccurate and untimely fire warnings for lithium battery energy storage boxes and the inability to avoid fire accidents in time, the inventors of this disclosure have creatively obtained a fire response control method and system for lithium battery energy storage boxes. Example 1

[0022] Figure 1 This application provides a diagram illustrating a fire response control method for a lithium battery energy storage box. The method is applied to a fire response control system, which is communicatively connected to a temperature acquisition device and a data interaction device. Figure 1 As shown, the method includes:

[0023] Step S100: Collect and obtain the battery compartment layout information of the lithium battery energy storage box;

[0024] Specifically, this application provides a fire response control method for a lithium battery energy storage box. The method is applied to a fire response control system, which is a system platform for fire early warning and fire management of the lithium battery energy storage box. A temperature acquisition device is a sensor for temperature acquisition, and a data interaction device is a device for acquiring control data from the lithium battery energy storage box. The fire response control system is communicatively connected to the temperature acquisition device and the data interaction device, enabling data exchange and transmission. Specifically, the lithium battery energy storage box includes multiple battery compartments, each containing batteries. The battery compartment layout information refers to the distribution of the multiple battery compartments within the lithium battery energy storage box.

[0025] Step S200: Read data from the lithium battery energy storage box through the data interaction device to obtain real-time control data;

[0026] Specifically, the data interaction device converts various changing physical quantities into analog electrical signals through corresponding sensors, then converts these analog electrical signals into digital signals for storage and preprocessing. It possesses functions of real-time acquisition, automatic storage, instant display, and automatic transmission. Real-time control data refers to the real-time operating data of the lithium battery energy storage box, including data such as charging voltage, discharging voltage, charging current, and discharging current.

[0027] Step S300: Deploy the temperature acquisition device using the battery compartment deployment information, wherein the temperature acquisition device has a acquisition location identifier;

[0028] Specifically, the temperature acquisition device is used to collect temperature data from the battery compartment. It includes various temperature sensors that can be selected and used according to the actual situation. The temperature acquisition device is installed in the lithium battery energy storage box according to the battery compartment layout information. It can be simply understood as installing a temperature acquisition device on each battery compartment. The temperature acquisition device has a collection location mark, which makes it easy to determine the collection location of temperature data and provides a basis for fire early warning and fire management of the lithium battery energy storage box.

[0029] Step S400: Collect temperature data using the temperature acquisition device to obtain temperature data acquisition results;

[0030] Specifically, temperature data is collected by deploying temperature acquisition devices to obtain temperature data acquisition results. The temperature data acquisition results include the acquisition results of each temperature acquisition device. In other words, the temperature data acquisition results are the temperature of each battery compartment.

[0031] Step S500: Collect historical detection data of the lithium battery energy storage box, wherein the historical detection data has a time sequence identifier;

[0032] Specifically, historical testing data refers to the testing data of lithium battery energy storage boxes over a period of time, such as the past month. Historical testing data includes historical temperature testing data, historical control data, and historical maintenance data of each battery compartment in the lithium battery energy storage box. The time sequence refers to the chronological order of the testing. The testing time of the historical testing data is marked according to the chronological order of the testing.

[0033] Step S600: Extract features from the historical detection data to construct a lithium battery feature dataset for the lithium battery energy storage box, wherein the lithium battery feature dataset includes feature categories and feature values;

[0034] Specifically, the lithium battery energy storage box includes multiple battery compartments, each containing batteries. The battery compartments that fail during historical maintenance are different. Feature extraction involves extracting abnormal features from historical detection data and constructing a lithium battery feature dataset based on these abnormal feature data. The lithium battery feature dataset includes feature categories and feature values. The feature category is the type of abnormality detected each time, and the feature value refers to the corresponding abnormality level.

[0035] Step S700: The time sequence identifier is fused with the lithium battery feature dataset, and the fusion result is used as the basic dataset to construct the anomaly monitoring model;

[0036] Specifically, by fusing time-series identifiers with lithium battery feature datasets, the detection time corresponding to abnormal data in the lithium battery feature dataset can be clearly obtained. Battery compartments that have experienced one or more anomalies can be prioritized for management. The data fusion results are used as the base dataset to construct an anomaly monitoring model. The anomaly monitoring model is a neural network model in machine learning, trained using the base dataset. In other words, the anomaly monitoring model has different monitoring thresholds for different battery compartments. For example, a low-level anomaly warning is issued when the temperature of a normal battery compartment exceeds 50°C. If a battery compartment has undergone multiple abnormal maintenance checks and its temperature exceeds 45°C, a low-level anomaly warning is also required. That is, different anomaly thresholds are set for batteries with different historical usage conditions to determine the warning level. The anomaly thresholds include temperature and control data thresholds. Based on this, the anomaly monitoring model is constructed to improve the accuracy of anomaly identification in lithium battery energy storage boxes.

[0037] Step S800: Input the temperature data acquisition results and the real-time control data into the anomaly monitoring model, and output the anomaly warning level information;

[0038] Specifically, the anomaly monitoring model is a functional model that analyzes temperature data acquisition results and real-time control data to obtain anomaly warning level information. In other words, the input data for the anomaly monitoring model are temperature data acquisition results and real-time control data, and the output data is anomaly warning level information. Different levels of warning information are set based on the temperature data acquisition results and real-time control data. The higher the level, the greater the degree of data anomaly. The anomaly warning level information includes the location of the anomaly. Since the temperature acquisition device has a acquisition location identifier, the acquisition location of the temperature data can be determined. Based on this, the location of the abnormal data can be identified. Therefore, the anomaly warning level information includes the anomaly warning level, the abnormal data, and the location of the anomaly.

[0039] Step S900: Generate multi-level fire response control data based on the abnormal warning level information and the battery compartment layout information;

[0040] Specifically, different levels of abnormal warnings require different fire response measures. For example, lower-level abnormal warnings may be addressed through physical cooling and heat dissipation measures, while higher-level abnormal warnings may require power outages for maintenance and repair. Based on this, the severity and location of the abnormality are determined according to the abnormal warning level information, and multi-level fire response control data is generated by combining the battery compartment layout information. This multi-level fire response control data includes multiple levels of fire control measures and their corresponding locations. The lower the abnormal warning level, the lower the level of the corresponding fire response control data. The lower the level of the fire response control data, the simpler the fire control measures, which may only involve simple physical cooling measures. The higher the level of the fire response control data, the more complex the fire control measures, which may require stopping work, power outages for maintenance, or even the use of fire-fighting equipment for fire control.

[0041] Step S1000: Manage the lithium battery energy storage box using the multi-level fire response control data.

[0042] Specifically, the lithium battery energy storage box is managed through multi-level fire response control data. Different levels of fire response control data correspond to different fire management methods, including cooling and early warning processing, thereby realizing fire management of the lithium battery energy storage box.

[0043] Among them, such as Figure 2 As shown, step S1010 in this embodiment includes:

[0044] Step S1011: Set the threshold for the monitoring and early warning level;

[0045] Step S1012: Determine whether the abnormal warning level information meets the supervision warning level threshold;

[0046] Step S1013: When the abnormal warning level information cannot meet the supervision warning level threshold, the normalized recovery temperature threshold is obtained by matching;

[0047] Step S1014: Perform early warning management on the lithium battery energy storage box according to the normalized recovery temperature threshold.

[0048] Specifically, a monitoring and early warning level threshold is set. This threshold is an indicator used to judge the level of abnormal early warning information. It is a level value that can be set according to actual conditions. For example, if there are 5 levels of abnormal early warning, the monitoring and early warning level threshold can be set to 2. This means that if the abnormality in the lithium battery energy storage box is within the monitoring and early warning level threshold range, it is considered that the abnormality is not serious, and the energy storage box can be automatically cooled. If the temperature meets the expected result through automatic cooling, the warning stops. If the warning level displayed by the abnormal early warning information does not meet the monitoring and early warning level threshold, a normalized recovery temperature threshold is obtained. The normalized recovery temperature threshold refers to the temperature of the lithium battery energy storage box when it is working normally and without any safety hazards. Management of the lithium battery energy storage box after issuing an early warning based on the normalized recovery temperature threshold, simply put, involves taking relevant measures (such as air conditioning cooling, heat dissipation, etc.) to restore the abnormal temperature of the lithium battery energy storage box to within the normalized recovery temperature threshold range. This achieves the technical effect of accurately judging abnormal data and targeting different levels of abnormal data.

[0049] In this embodiment, step S1020 includes:

[0050] Step S1021: Obtain a feedback monitoring window based on the abnormal warning level information;

[0051] Step S1022: The temperature acquisition device performs feedback temperature monitoring based on the feedback monitoring window to obtain the feedback temperature monitoring result;

[0052] Step S1023: Determine whether the feedback temperature monitoring result within the feedback monitoring window meets the normalization recovery temperature threshold;

[0053] Step S1024: When the feedback temperature monitoring result can meet the normalized recovery temperature threshold, the current warning of the lithium battery energy storage box is lifted.

[0054] Specifically, a feedback monitoring window is obtained based on the abnormal warning level information. This means that after acquiring the abnormal warning level information, the lithium battery energy storage box undergoes abnormal processing. The feedback monitoring window refers to a time period for temperature monitoring, which is also the time period for abnormal processing. Generally, the higher the abnormal warning level, the longer the abnormal processing time, and the larger the corresponding feedback monitoring window time range. The battery compartment temperature is monitored within this time period using a temperature acquisition device, and the feedback temperature monitoring result is obtained. This result represents the battery compartment temperature after abnormal processing. It is then determined whether the feedback temperature monitoring result within the feedback monitoring window meets the normal recovery temperature threshold. When the feedback temperature monitoring result meets the normal recovery temperature threshold, it indicates that the battery compartment temperature has dropped to the normal operating temperature range. At this point, the lithium battery energy storage box is in a normal and safe operating state, and no further warning is needed. The current warning for the lithium battery energy storage box is then deactivated, achieving the technical effect of feedback detection of abnormal processing results and improving the accuracy of warnings.

[0055] In this embodiment, step S900 further includes:

[0056] Step S910: When the abnormal warning level information meets the supervision warning level threshold, the battery compartment is matched and associated according to the abnormal warning level information and the battery compartment layout information;

[0057] Step S920: Generate power-off control information for the associated battery compartment;

[0058] Step S930: Determine the multi-level cooling control information, and obtain the multi-level fire response control data based on the power outage control information and the multi-level cooling control information.

[0059] Specifically, it is determined whether the abnormal warning level information meets the supervisory warning level threshold. If the abnormal warning level information meets the supervisory warning level threshold, then the associated battery compartment is matched based on the abnormal warning level information and the battery compartment layout information. In simple terms, the battery compartment where the abnormality occurred is determined based on the collection location of the abnormal temperature data in the abnormal warning level information and the battery compartment layout information. The battery compartment where the abnormality occurred is the associated battery compartment. Furthermore, power-off control information for the associated battery compartments is generated to control the disconnection of the circuit connections of the associated battery compartments. Multi-level cooling control information is determined based on the abnormal warning level information. Different warning levels require different cooling control methods. For example, a low warning level indicates that the abnormal temperature is not very high, and cooling methods such as air conditioning or fan cooling can be used. A high warning level can be cooled by liquid cooling or separate heat dissipation after power failure. Multi-level fire response control data is obtained based on the power-off control information and the multi-level cooling control information. This multi-level fire response control data includes different cooling control measures, achieving targeted cooling treatment for different levels of abnormal warnings. This avoids resource waste while ensuring the safe operation of the lithium battery energy storage box.

[0060] In this embodiment, step S1023 further includes:

[0061] Step S10231: When the feedback temperature monitoring result cannot meet the normalized recovery temperature threshold, the temperature change trend of the feedback temperature monitoring result is obtained;

[0062] Step S10232: Obtain the extreme and average temperatures from the feedback temperature monitoring results;

[0063] Step S10233: Generate a correlation fire early warning coefficient based on the temperature change trend, the temperature extreme values, and the temperature average values;

[0064] Step S10234: The abnormal warning level information is weighted and calculated using the associated fire warning coefficient, and fire management is carried out based on the weighted calculation result.

[0065] Specifically, it is determined whether the feedback temperature monitoring results within the feedback monitoring window meet the normalized recovery temperature threshold. When the feedback temperature monitoring results do not meet the normalized recovery temperature threshold, the temperature change trend of the feedback temperature monitoring results is obtained. The temperature change trend can be divided into three trends: temperature rising trend, temperature fluctuation trend, and temperature falling trend. The temperature rising trend means that the temperature in the feedback temperature monitoring results is rising. The temperature fluctuation trend means that the temperature in the feedback temperature monitoring results is fluctuating within a range. The temperature falling trend means that the temperature in the feedback temperature monitoring results is falling. Furthermore, the extreme and average temperatures from the feedback temperature monitoring results are obtained. Extreme temperatures include the maximum and minimum temperature values, while the average temperature is calculated by averaging all temperature values ​​from the feedback monitoring results. Then, a correlation fire warning coefficient is generated based on the temperature change trend, extreme temperatures, and average temperatures. Specifically, the temperature change trend, extreme temperatures, and average temperatures are weighted and distributed, and a weighted calculation is performed based on the weight distribution results to obtain the correlation fire warning coefficient. The correlation fire warning coefficient represents the degree of temperature anomaly. The abnormal warning level information is weighted and calculated using the correlation fire warning coefficient. Based on the weighted calculation results, personnel and equipment arrangements are made for fire management. The larger the weighted calculation result, the more fire-fighting resources are needed, thus improving the accuracy and efficiency of fire management.

[0066] The fire response control system is communicatively connected to the image acquisition device and the smoke monitoring device, such as... Figure 3 As shown, step S800 in this embodiment includes:

[0067] Step S1110: The image acquisition device is used to acquire an image of the lithium battery energy storage box to obtain the image acquisition result;

[0068] Step S1120: Collect smoke from the lithium battery energy storage box using the smoke monitoring device and obtain the smoke collection results;

[0069] Step S1130: Generate auxiliary warning features based on the image acquisition results and the smoke acquisition results;

[0070] Step S1140: Determine whether the auxiliary early warning feature matches the abnormal early warning level information;

[0071] Step S1150: When the auxiliary warning feature does not match the abnormal warning level information, the warning correction of the abnormal warning level information is performed according to the auxiliary warning feature;

[0072] Step S1160: Conduct fire safety management of the lithium battery energy storage box based on the early warning correction results.

[0073] Specifically, image acquisition devices, such as cameras and video cameras, are used to acquire images of the battery compartment inside the lithium battery storage box. Smoke detection devices, such as smoke detectors, are used to detect smoke within the lithium battery storage box. The image acquisition device acquires images of the battery compartment inside the lithium battery storage box, obtaining image acquisition results. The smoke detection device collects smoke from the lithium battery storage box, obtaining smoke collection results, including smoke concentration. The image acquisition results and smoke collection results are analyzed to generate auxiliary warning features. Simply put, the image acquisition results are analyzed to determine if there is an open flame or blackened components in the battery compartment, and the smoke collection results are analyzed for smoke concentration characteristics; these characteristics are the auxiliary warning features. The process involves determining whether the auxiliary warning features match the abnormal warning level information. In other words, it involves determining whether the auxiliary warning features will appear in the lithium battery energy storage box under the current abnormal warning level information. If they do, it means that the auxiliary warning features and the abnormal warning level information match. If the auxiliary warning features do not appear in the lithium battery energy storage box under the current abnormal warning level information, it means that the auxiliary warning features and the abnormal warning level information do not match, and the abnormal warning level information can be considered inaccurate. In this case, the abnormal warning level information is corrected based on the auxiliary warning features to make it match the auxiliary warning features. Then, fire management of the lithium battery energy storage box is carried out based on the warning correction results to achieve the technical effect of ensuring the accuracy of the warning.

[0074] In this embodiment, step S1200 includes:

[0075] Step S1210: Perform a statistical analysis of the warning signs in the lithium battery energy storage box to obtain the statistical results of the warning signs;

[0076] Step S1220: Based on the statistical results of the warning signs, perform battery compartment feature analysis on the lithium battery energy storage box to obtain the battery compartment feature analysis results;

[0077] Step S1230: Perform maintenance and replacement of the lithium battery energy storage box based on the battery compartment feature analysis results.

[0078] Specifically, the system performs early warning sign statistics on lithium battery energy storage boxes, obtaining the results including the number of warnings and their levels. Based on these results, the system analyzes the battery compartment characteristics to assess the wear and tear. For example, a high number of warnings at high levels indicates severe wear and tear on the battery compartment. This analysis provides the battery compartment characteristic analysis results, which are then used to maintain and replace the lithium battery energy storage boxes. In cases of severe wear, the entire lithium battery energy storage box is replaced; in cases of less severe wear, only parts of the battery compartment are repaired or batteries are replaced. This ensures the safe operation of the lithium battery energy storage boxes.

[0079] Based on the above analysis, this disclosure provides a fire response control method for lithium battery energy storage boxes. In this embodiment, real-time control data and temperature data acquisition results of the lithium battery energy storage box are obtained through communication between a temperature acquisition device and a data interaction device. Anomaly level warning information is generated based on the real-time control data and temperature data acquisition results. Different warning thresholds are set according to the anomaly level warning information, and multi-level fire control is performed to conduct fire management of the lithium battery energy storage box. This achieves the technical effect of improving the accuracy of fire warning, improving the pertinence and efficiency of fire management, and ensuring the safe operation of the lithium battery energy storage box.
