[0050] In recent years, with the rapid development of electronic products, new energy vehicles and other industries, the application of lithium batteries in daily life and work has become more and more widespread, and the production capacity of lithium batteries has been surprisingly improved. However, while lithium batteries bring us convenience, they also hide huge safety hazards. In recent years, explosions caused by improper storage and use of lithium batteries have occurred repeatedly. Some consumers have experienced explosions when using lithium battery products, and some lithium battery manufacturers have experienced explosions during storage, transportation, application, and recycling. How to safely store and transport a large number of lithium batteries has become a problem that must be taken seriously.

[0051] The storage safety detection of lithium batteries is usually based on two parameters of temperature and specific gas concentration for judgment, but when the temperature detector or gas detector fails, it cannot effectively ensure timely fire extinguishing, causing a greater safety hazard.

[0052] The lithium battery in the present application is stored in a storage cabin, and a spraying system is arranged at the top of the storage cabin,

[0053] The following will be described in detail with reference to the accompanying drawings. Figs. 1 to 3 The present application will be further described in detail.

[0054] In order to improve the safety of lithium battery storage, the present application provides a fire extinguishing method based on lithium battery storage.

[0055] Reference Fig. 1 A fire extinguishing method based on lithium battery storage, comprising the following steps:

[0056] S101: Obtain temperature detection data and gas detection data.

[0057] The temperature detection data includes the temperature of each lithium battery. A temperature detector is arranged above each lithium battery, and each lithium battery has a corresponding number, and the position of each lithium battery in the storage bin and the corresponding number are stored in the database. When collecting temperature detection data, the corresponding lithium battery number and corresponding temperature value are obtained. At the same time, a gas detector is arranged in the storage cabin of the lithium battery for detecting the concentration of carbon monoxide and hydrogen generated when the temperature of the lithium battery rises.

[0058] S102: Determine abnormal data according to the temperature detection data and the gas detection data, and further determine the abnormal detection equipment.

[0059] During the storage of lithium batteries, the detector device may be faulty due to long-term operation. At this time, the detection device may still have readings, but the readings are not accurate. Once the fire extinguishing measure of the lithium battery storage bin is started, manual maintenance is required to restart. Therefore, it is necessary to first distinguish whether the detection device is faulty, then judge whether the data is truly abnormal, and determine the accurate data.

[0060] In a first aspect, the temperature detection data is first screened for abnormal temperature values. The abnormal temperature values are generally screened for being greater than a preset detection temperature threshold, which is set to be less than a temperature safety threshold, which is a threshold for triggering fire-fighting measures. This is to deal with the situation where the temperature probe fails and the corresponding lithium battery fire cannot trigger fire-fighting measures in time.

[0061] When there is an abnormal temperature value, it is necessary to further determine whether there is a temperature probe failure. First, a temperature distribution map in the storage bin is generated according to the temperature detection data. When an abnormal temperature value occurs, there are three cases. In the first case, the temperature probe corresponding to the abnormal temperature value is not faulty, and the abnormal temperature should show a regular distribution trend. The temperature detection data values near the abnormal temperature value should be the same or similar. If there is a large deviation value at this time, the corresponding value is an error value, the corresponding temperature probe is faulty, and the remaining values are identified as accurate values. In the second case, the temperature probe corresponding to the abnormal temperature value is faulty. At this time, the temperature detection data values near the abnormal temperature value do not change significantly from the average temperature value, and the abnormal temperature value is identified as an accurate value. In the third case, there is no temperature probe failure, and the abnormal temperature value is accurate.

[0062] If the temperature probe fails, the theoretical temperature value of the faulty temperature probe needs to be calculated based on the temperature detection data of the temperature probe adjacent to the faulty temperature probe. The specific implementation is as follows: Obtain the temperature change curve of the lithium battery before the lithium battery burns and the temperature change curve of the adjacent lithium battery in the historical data. Then, the temperatures of the lithium battery before the lithium battery burns and the adjacent lithium battery are extracted at the same time point to obtain a comparison table of the lithium battery temperature before the lithium battery burns and the adjacent lithium battery temperature. Finally, according to the temperature detection data of the adjacent temperature probe, the corresponding temperature value in the comparison table is selected as the theoretical temperature value of the faulty temperature probe.

[0063] In a second aspect, the gas detection data is another indicator for starting fire-fighting measures. Therefore, it is necessary to determine whether the gas detection device is faulty, and whether the concentrations of carbon monoxide and hydrogen are abnormal.

[0064] The theoretical gas concentration corresponding to the accurate abnormal temperature value in the historical data is obtained. According to the theoretical gas concentration and the gas detection data, it is determined whether the gas detection device is abnormal. When the gas detection device is normal, it is determined whether the gas detection data exceeds the preset gas concentration safety threshold. At this time, the gas detection data is accurate. When the gas detection data is abnormal, it is determined whether the theoretical gas concentration exceeds the preset gas concentration safety threshold. At this time, the theoretical gas concentration is considered to be accurate.

[0065] S103: judging whether to start the fire-fighting measure according to the accurate data.

[0066] The accurate data includes accurate abnormal temperature value, theoretical temperature value, accurate gas detection data and theoretical gas concentration.

[0067] When the accurate abnormal temperature value or the theoretical temperature value exceeds the preset temperature safety threshold, the fire-fighting measure is started. Or, when the accurate gas detection data or the theoretical gas concentration exceeds the preset gas concentration safety threshold, the fire-fighting measure is started.

[0068] When cooling is performed, different spraying devices are used for the position of the accurate abnormal temperature or the theoretical temperature value. The lithium battery number corresponding to the abnormal temperature value is obtained, and then the spraying device corresponding to the lithium battery number is started according to the lithium battery number.

[0069] The application provides a fire-fighting system based on lithium battery storage, which adopts the following technical scheme:
