[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] like Figure 1 As shown, the present invention provides a fire fighting method in a drone hangar, comprising:

[0031] The hangar body is equipped with functional modules for fire protection, including fire detection module, central control module, fire extinguishing module, data storage module and alarm module; all functional modules are controlled by the central control module and are carried out in the following steps:

[0032] Step S1: Fire detection: The fire detection module monitors the environmental data in the hangar, including temperature, smoke concentration and thermal imaging information, and determines whether there is a fire risk based on the fire risk assessment value and preset value calculated by the central control module;

[0033] Step S2: Data analysis: When the fire risk assessment value exceeds the preset value, the central control module generates a fire extinguishing control instruction based on the fire source location and fire information;

[0034] Step S3: fire extinguishing operation; the fire extinguishing module performs corresponding fire extinguishing operation according to the received fire extinguishing control instruction;

[0035] Step S4: data recording; storing the data during fire detection, risk assessment and fire extinguishing operation in the data storage module;

[0036] Step S5: Alarm; send alarm information to management personnel through the alarm module.

[0037] In this embodiment, the hangar of the present invention is equipped with multiple fire protection function modules, including a fire detection module, a central control module, a fire extinguishing module, a data storage module and an alarm module. The following are the specific implementation steps and implementation methods of the method:

[0038] Step S1: Fire detection

[0039] Multiple sensors are installed in the hangar, including temperature sensors, smoke sensors, and thermal imaging cameras. The temperature sensor monitors the temperature changes in the hangar in real time, the smoke sensor detects the smoke concentration in the air, and the thermal imaging camera is used to detect the heat source in the hangar and output image information. When the temperature, smoke concentration, and information displayed or processed by the thermal imaging exceed the preset values, the fire detection module transmits the data to the central control module. The central control module calculates the fire risk assessment value of the current hangar through the preset fire risk assessment algorithm and compares it with the preset value. If the risk assessment value exceeds the preset value, the system determines that there is a fire risk and enters the data analysis step.

[0040] Step S2: Data analysis

[0041] If the fire risk assessment value exceeds the preset value, the central control module performs data analysis. Through the real-time image information of the thermal imaging camera, the central control module can determine the location of the fire source, the size of the fire and the spread of the fire. At the same time, the central control module analyzes the fire development trend through algorithms, determines whether the fire has spread to the dangerous area, and generates corresponding fire extinguishing control instructions.

[0042] Step S3: Fire extinguishing operation

[0043] The fire extinguishing module automatically performs fire extinguishing operations according to the fire extinguishing control instructions sent by the central control module. The fire extinguishing module includes a variety of fire extinguishing equipment, such as sprinkler fire extinguishers, gas fire extinguishers and dry powder fire extinguishers, and can select the appropriate fire extinguishing method according to the location of the fire source and the size of the fire. For example, if the fire source is small and localized, the system can activate the gas fire extinguisher; if the fire is large, the sprinkler fire extinguisher can be activated for fire extinguishing, and if the fire is on important components, the dry powder fire extinguisher can be activated for fire extinguishing.

[0044] Step S4: Data recording

[0045] After the fire extinguishing operation is completed, the system will record all the data during the fire detection, risk assessment and fire extinguishing operation, and transfer them to the data storage module. The data storage module can use cloud storage or local hard disk storage to ensure that all relevant data can be saved. The data includes but is not limited to fire detection time, fire risk assessment value, fire extinguishing operation duration, fire source location and other information. The data storage module can not only provide managers with detailed historical records, but also serve as an important basis for post-analysis and evaluation.

[0046] Step S5: Alarm

[0047] If the system detects a fire risk or fire occurs, the alarm module will immediately send an alarm message to the hangar manager through the wireless communication system. The alarm content includes detailed data such as the fire risk assessment value, the location of the fire source, the fire information and the fire extinguishing instructions to ensure that the manager can respond.

[0048] The present invention has the following advantages:

[0049] Automated monitoring and control: Through fire detection, risk assessment, fire extinguishing control and alarm functions, the present invention can automatically perform fire emergency treatment without human intervention, thereby improving firefighting efficiency.

[0050] Intelligent fire extinguishing: The system automatically selects the appropriate fire extinguishing method based on the location and size of the fire, avoiding delays and errors in manual operation.

[0051] Real-time data recording and tracing: The system records and stores all fire-related data, providing a basis for subsequent analysis, auditing and improvement.

[0052] Alarm mechanism: timely notify management personnel through a variety of alarm methods, shorten the response time and ensure the safety of personnel and equipment.

[0053] Preferably, in step S1 to step S2, the central control module calculates the fire risk assessment value based on the following formula:

[0054] R = α·T + β·S + γ·H;

[0055] During the detection process, if R ≥ R t , indicating that the fire risk is high, the central control module starts the fire extinguishing operation; if R<R t , indicating that the risk is low, the system remains on standby, issuing warnings and recording data;

[0056] Where T is the temperature abnormality value detected by the temperature sensor, S is the smoke concentration detected by the smoke sensor, H is the thermal imaging area scanned by the infrared camera, and R t is the preset value, α, β, γ are the preset weight parameters, α, β, γ can be adjusted according to the historical data of the fire detection module; the central control module adjusts the weight parameters α, β, γ according to the data of each operation in the UAV hangar.

[0057] In this embodiment, T is the abnormal temperature value detected by the temperature sensor, indicating whether there is abnormally high temperature or fire source in the hangar. S is the smoke concentration detected by the smoke sensor, reflecting whether there is smoke in the hangar. A high smoke concentration usually means a fire. H is the area of ​​the thermal imaging region scanned by the infrared thermal imaging camera, indicating the area of ​​the heat source area that may exist in the hangar. The larger the area, the higher the fire risk.

[0058] Each factor has a corresponding weight parameter:

[0059] α is the weight of the temperature anomaly T, indicating the importance of temperature in risk assessment.

[0060] β is the weight of smoke concentration S, which indicates the influence of smoke concentration on fire risk assessment.

[0061] γ is the weight of the thermal imaging area H, which represents the influence of the thermal imaging area in fire risk assessment.

[0062] The central control module will dynamically adjust these weight parameters based on historical data to make each fire risk assessment more accurate. For example, if historical data shows that temperature anomaly T has a strong predictive power for fire risk, α can be increased.

[0063] If the calculated fire risk assessment value R is greater than or equal to the preset risk threshold R t, that is, R ≥ R t , it is judged that there is a fire risk and the central control module will start the fire extinguishing operation.

[0064] If R is less than R ≥ R t , the fire risk is considered low, the system will remain on standby, and record data and issue warnings.

[0065] The temperature sensor detected that the temperature in a certain area of ​​the hangar was T=75°, which was much higher than normal, indicating that there might be a fire source.

[0066] The smoke concentration detected by the smoke sensor is S=0.8, which is higher than the normal range, indicating that there may be smoke in the air in the hangar.

[0067] The thermal imaging area scanned by the thermal imaging camera is H = 12 m 2 , which means that the area of ​​the heat source is larger and the risk of fire is higher.

[0068] Fire risk assessment:

[0069] The central control module calculates the fire risk assessment value R based on the sensor data:

[0070] Assume α=0.5, β=0.3, γ=0.2, these weight parameters can be adjusted according to historical data.

[0071] Substitute into the formula: R = 0.5 75 + 0.3 0.8 + 0.2 12 = 40.14

[0072] Determine the fire risk:

[0073] Assume the preset fire risk value, R t =40

[0074] Since R=40.14≥R t , the central control module determines that there is a fire risk and immediately starts the fire extinguishing operation.

[0075] Fire extinguishing operation:

[0076] Based on the location of the fire source and the assessment of the fire intensity, the central control module sends a fire extinguishing instruction to the fire extinguishing module, which activates the gas fire extinguishing system to extinguish the fire source.

[0077] Data logging and alarms:

[0078] After the fire extinguishing operation is completed, all fire detection data, risk assessment data and fire extinguishing process data will be stored in the data storage module for subsequent review and analysis.

[0079] At the same time, the alarm module sends an alarm message to the hangar manager, informing him that the fire risk has been confirmed and fire-fighting measures have been taken.

[0080] In this embodiment, the present invention has the following advantages:

[0081] 1. Adjust weight parameters based on historical data to make each fire risk assessment more accurate.

[0082] 2. The central control module automatically determines the fire risk based on real-time data and calculation results, quickly initiates fire-fighting operations, reduces human intervention, and improves fire-fighting efficiency.

[0083] 3. Multiple factors such as temperature, smoke and thermal imaging area work together to improve the accuracy of fire risk assessment and reduce the possibility of missed or false alarms.

[0084] Preferably, in step S2, the fire extinguishing control instruction includes selecting a fire extinguishing method and determining a fire extinguishing area.

[0085] Thermal imaging data and temperature sensor data received by the central control module help determine the location of the fire and the severity of the fire.

[0086] The central control module can accurately locate the fire source through the thermal imaging area scanned by the thermal imaging camera. Usually, the thermal imaging image will show the hot zone where the fire source is located, and the specific location of the fire source can be calibrated through coordinate data.

[0087] The fire source information is obtained by analyzing the temperature distribution and smoke density of the area. For example, the temperature near the fire source is T = 150 ° C, while the temperature of the area far from the fire source is normal. The smoke density at the fire source is S = 0.9, and the fire source coordinates are displayed.

[0088] Preferably, the fire extinguishing module includes a sprinkler fire extinguisher, a gas fire extinguisher and a dry powder fire extinguisher, and the fire extinguishing methods include sprinkler fire extinguishing, gas fire extinguishing and dry powder fire extinguishing.

[0089] In this embodiment, the fire extinguishing module includes three types of fire extinguishers: sprinkler fire extinguisher, gas fire extinguisher and dry powder fire extinguisher. According to the specific situation of the fire, the central control module will select the appropriate fire extinguishing method and command the corresponding fire extinguishing equipment to perform the fire extinguishing operation. The specific implementation steps are as follows:

[0090] 1. Sprinkler fire extinguisher:

[0091] If a major fire accident occurs, the fire in the hangar may spread to the outside and cause damage to the external environment. Using a sprinkler fire extinguisher can quickly reduce the temperature of the fire source.

[0092] 2. Gas fire extinguisher:

[0093] Gas fire extinguishers are suitable for electrical fires or flammable gas fires. Since gas fire extinguishers do not involve water or dry powder, they will not cause secondary damage to electrical equipment. If the fire assessment shows that the fire source is located in the electrical equipment, the central control module will select a gas fire extinguisher to extinguish the fire. Common gas fire extinguishing agents include carbon dioxide, nitrogen or clean gas. The fire extinguishing module will release the gas fire extinguishing agent to the fire source area to suppress the burning of the fire source.

[0094] 3. Dry powder fire extinguisher:

[0095] Dry powder fire extinguishers are suitable for various types of fires, including metal fires, oil fires, etc. Dry powder fire extinguishers extinguish flames by covering the fire source and isolating it from oxygen. The central control module selects dry powder fire extinguishers based on the fire assessment value, especially when oil and metal materials are on fire.

[0096] Preferably, the fire extinguishing area is determined based on thermal imaging data detected by an infrared camera.

[0097] In this embodiment, the determination of the fire extinguishing area is based on the thermal imaging data of the infrared camera. Through thermal imaging technology, the central control module can identify the specific location of the fire source and the severity of the fire, and determine the fire extinguishing area according to the heat distribution of the fire source. The infrared camera continuously monitors the temperature changes in the hangar and generates a thermal map through thermal imaging technology. The thermal map can show the temperature distribution of each area in the hangar, especially the high temperature area at the location of the fire source. The central control module updates the location of the fire source and the fire situation in real time through the thermal imaging data of the infrared camera. The infrared camera detects the location of the fire source, and the central control module determines the thermal imaging area where the fire source is located. For example, if the temperature at a certain location exceeds the preset fire source threshold, the central control module will use the area as the key area for fire extinguishing. If the temperature near the fire source is high and the temperature in the surrounding area shows an upward trend, the central control module will automatically expand the fire extinguishing area to ensure that the spread of the fire source is effectively controlled. For example, if the thermal imaging image shows that the fire source is on the left side of the hangar and the temperature rises rapidly, the central control module will use the left area as the main area for fire extinguishing. As the fire extinguishing operation proceeds, the central control module will dynamically adjust the fire extinguishing area according to the real-time thermal imaging data. For example, suppose that after a fire extinguishing operation, the thermal image shows that the temperature of the left fire source decreases, but the temperature of the right side increases. The central control module will adjust the fire extinguishing area and include the right area back into the fire extinguishing range.

[0098] Preferably, the central control module can also establish a fire risk prediction model based on historical data and real-time monitoring data, and predict the probability of fire occurrence in the future based on the fire risk prediction model.

[0099] Specifically, the central control module collects fire-related data over a period of time through the data storage module. These data include temperature changes, smoke concentration, changes in thermal imaging areas, and records of fire extinguishing equipment use. These historical data include fire occurrences in different seasons and weather conditions, as well as the impact of various environmental factors on fire occurrence. The central control module performs statistical analysis on the collected historical data to identify the patterns of fire occurrence. For example, in certain seasons or weather conditions, the frequency of fire occurrence is higher, or certain specific environmental factors (such as high temperature, dryness, etc.) are prone to fire.

[0100] Furthermore, through historical data analysis, the central control module establishes a model of potential influencing factors of fire occurrence and uses these data as the basis of the prediction model. During the model establishment process, the central control module will make dynamic adjustments based on real-time monitoring data and historical data. For example, if certain factors (such as temperature) have a greater impact on the occurrence of fire, the model will automatically adjust the weight α of the relevant parameters. The central control module calculates the probability of fire occurrence in the future (such as 1 hour, 12 hours, 24 hours) based on the fire risk prediction model. The predicted probability of fire occurrence in the next 12 hours is 10%, which means that the risk of fire occurrence in the next 12 hours is low. Based on the predicted probability of fire occurrence, the central control module determines whether an early warning is needed. When the predicted probability of fire occurrence exceeds the preset risk threshold, the system will trigger the early warning mechanism and notify the management personnel to take preventive measures. If the probability of fire occurrence reaches 20% or higher, the system will automatically send an alarm message to remind the management personnel to increase fire monitoring in the hangar, or arrange patrols and other preventive measures.

[0101] In some optional embodiments, the central control module presents the prediction results of the probability of fire occurrence to the management personnel in a graphical manner. For example, the prediction results can be displayed in the form of trend graphs, heat maps, etc., to help the management personnel more intuitively understand the fire risks in the future.

[0102] Preferably, in step S5, the alarm module can send the alarm information to the fire department and the mobile terminals of relevant personnel, and provide real-time video images of the fire scene.

[0103] When R ≥ R t, the central control module determines that the fire risk is high and triggers the alarm module. Optionally, the alarm module sends the alarm information to the preset fire department and the mobile terminal of relevant personnel through the wireless communication module (such as Wi-Fi, 4G / 5G network, etc.). The alarm information includes basic information about the fire, the location of the hangar in the outside world, the fire risk assessment value, the location of the fire source, etc. At the same time, the alarm information also includes the current environmental data in the hangar (temperature, smoke concentration and thermal imaging data) so that firefighters can better understand the severity of the fire. The alarm information also includes real-time video images in the hangar, which are transmitted in real time through cameras installed in the hangar to help managers understand the situation at the fire scene more intuitively.

[0104] Preferably, in step S3, the fire extinguishing module preferentially extinguishes the parking platform in the hangar body.

[0105] In this embodiment, after receiving the fire extinguishing control command, the fire extinguishing module first extinguishes the parking platform in the hangar body. The parking platform is one of the most critical areas in the drone hangar. Prioritizing fire extinguishing can effectively reduce the loss of drone equipment and ensure the safety of the hangar.

[0106] In summary, the present invention provides a fire fighting method based on a drone hangar, which can efficiently and intelligently perform fire emergency handling without human intervention through fire detection, risk assessment, fire extinguishing control and alarm functions. The method monitors the fire risk in the hangar in real time, and automatically selects a suitable fire extinguishing method according to the location of the fire source and the fire situation. By dynamically adjusting the weight parameters and prediction model of the fire risk assessment, the system can give early warning before the fire occurs, further reducing fire losses. In the present invention, it can help managers to fully understand the situation at the fire scene. The present invention is highly automated and intelligent, and can effectively ensure the safety of the drone hangar and improve the efficiency of fire emergency handling.

[0107] The working principle of the fire fighting method in the drone hangar described in the present invention is:

[0108] The main body of the hangar is equipped with a fire protection module, which is used to monitor the environmental data in the hangar in real time. The temperature changes in the hangar and the smoke concentration in the air are monitored. The thermal imaging camera scans the heat source in the hangar and generates thermal imaging images. When the detected temperature, smoke concentration or thermal imaging area exceeds the preset value, the fire detection module transmits the data to the central control module. After receiving the sensor data, the central control module calculates the fire risk assessment value through the preset fire risk assessment algorithm and compares it with the preset value. If the risk assessment value exceeds the preset value, the system determines that there is a fire risk and enters the data analysis stage. In the data analysis stage, the central control module analyzes the spread trend and severity of the fire according to the fire source location, fire information and thermal imaging data, and generates a fire extinguishing control instruction. The fire extinguishing module performs the fire extinguishing operation according to the received fire extinguishing instruction, selects the appropriate fire extinguishing method and determines the fire extinguishing area. After the fire extinguishing operation is completed, the system will record and store all the data during the fire detection, risk assessment and fire extinguishing operation in the data storage module. At the same time, the alarm module will send alarm information to the management personnel, including the fire risk assessment value, the fire source location, the fire information and the real-time video image, to ensure that the management personnel can respond in time. Through historical data and real-time monitoring data, the central control module can also establish a fire risk prediction model to predict the probability of fire in the future, and trigger an early warning mechanism based on the prediction results so that preventive measures can be taken in advance.

[0110] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
