[0036] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Next, in conjunction with Figures 1 to 4 , the embodiments of the present invention will be described.

[0038] According to an embodiment of the present invention, as Figure 1 shown, on the one hand, a fire prevention system for a drone hangar is provided, including: a drone hangar and a battery area 2, a circuit area 1, a parking area 13 and a plurality of fire extinguishing devices arranged in the drone hangar; both the battery area 2 and the circuit area 1 are arranged at the bottom of the drone hangar; the fire prevention system further includes:

[0039] A training module for training a deep learning model based on the historical fire data of the drone hangar, where the fire data includes the internal fire data and external fire data of the drone hangar;

[0040] A detection module installed on the drone hangar for detecting the real-time fire data of the drone hangar;

[0041] A decision-making module for combining the real-time fire data and the trained deep learning model to obtain the fire source information inside and outside the drone hangar, and dynamically planning a fire extinguishing plan according to the fire source information; the fire source information includes the fire source location and the fire source spreading speed;

[0042] A control module 12 for controlling at least one fire extinguishing device to work based on the fire extinguishing plan.

[0043] In this embodiment, the training module uses the historical fire data of the drone hangar to train the deep learning model, so that the deep learning model can learn the laws and patterns of the occurrence and development of fires, providing a basis for subsequent prediction and decision-making. Among them, the historical fire data covers the fire conditions inside and outside the drone hangar, including information such as the fire starting time, location, fire size, temperature, and smoke concentration.

[0044] The detection module is installed on the drone hangar. Through the detection module, the environmental information around and inside the drone hangar can be obtained in real time, thereby generating corresponding fire data and transmitting the real-time fire data to the decision-making module, providing the latest fire data for the decision-making module. The decision-making module combines the real-time fire data with the trained deep learning model, predicts the real-time fire data through the deep learning model, and obtains the fire source information inside and outside the drone hangar, such as the fire source location and the fire source spreading speed, etc.; then dynamically plans a fire extinguishing plan according to the fire source information and transmits the fire extinguishing plan to the control module 12. For example, if the fire source is located in the corner of the drone hangar and the spreading speed is slow, a local fire extinguishing plan will be formulated; if the fire source spreads quickly and over a large area, multiple fire extinguishing devices will be called to work simultaneously.

[0045] The control module 12 controls at least one fire extinguishing device to work according to the received dynamically planned fire extinguishing plan to complete the fire extinguishing work. Through the cooperation between the deep learning model and multiple modules, the present invention realizes the effective monitoring and processing of the fire in the drone hangar, improves the response speed of the early warning of the drone hangar, and effectively improves the efficiency and accuracy of the drone hangar in dealing with fires by dynamically planning the fire extinguishing plan.

[0046] In one embodiment, the detection module includes: a plurality of image recognition units 10 arranged outside the drone hangar, and an infrared thermal imager 7, a gas sensor 8, and a temperature and humidity sensor 9 arranged inside the drone hangar; the infrared thermal imager 7 is used to identify the temperature rise inside the drone hangar; the gas sensor 8 is used to detect the smoke concentration information inside the drone hangar; the temperature and humidity sensor 9 is used to detect the temperature information and humidity information inside the drone hangar; the image recognition unit 10 is used to detect the fire source information outside the drone hangar. Through the cooperation of the infrared thermal imager 7, the gas sensor 8, the temperature and humidity sensor 9, and the image recognition unit 10, the fire source type of the drone hangar can be effectively detected, so that the misjudgment rate of the fire source type can be effectively reduced, and the accuracy of dealing with the fire can be further improved.

[0047] In one embodiment, the plurality of image recognition units 10 are respectively installed on the periphery of the drone hangar, and are used to obtain the image information on the periphery of the drone hangar and determine the fire source information outside the drone hangar according to the image information.

[0048] In this embodiment, the image recognition unit 10 can be installed on the front, rear, left, and right sides of the drone hangar, and different numbers of image recognition units 10 can also be installed on each side according to actual usage requirements. Through the cooperation of the plurality of image recognition units 10, the image information around the drone hangar can be obtained, and thus the fire source information outside the drone hangar can be determined according to the image information.

[0049] In one embodiment, the fire extinguishing device includes a battery area fire extinguishing device 4, a circuit area fire extinguishing device 5, and an external fire extinguishing device 11; the battery area fire extinguishing device 4 is arranged near the battery area 2, the circuit area fire extinguishing device 5 is arranged near the circuit area 1, and the external fire extinguishing device 11 is arranged outside the drone hangar and on the top of the drone hangar.

[0050] In this embodiment, the battery area fire extinguishing device 4 is arranged near the battery area 2 and on the inner wall of the drone hangar; when it is necessary to extinguish the fire in the battery area 2, the battery area fire extinguishing device 4 can be activated, and heptafluoropropane gas is sprayed into the battery area 2 through the battery area fire extinguishing device 4 to extinguish the fire. The circuit area fire extinguishing device 5 is arranged near the circuit area 1 and on the inner wall of the drone hangar; when it is necessary to extinguish the fire in the circuit area 1, the circuit area fire extinguishing device 5 can be activated, aerosol fire extinguishing agent is sprayed into the circuit area 1 through the circuit area fire extinguishing device 5, and the circuit power supply is cut off at the same time. While extinguishing the fire, the spread of the fire is prevented from further expanding. The external fire extinguishing device 11 is arranged outside the drone hangar and on the top of the drone hangar. When it is necessary to extinguish the fire outside the drone, high-pressure water mist can be sprayed around the drone hangar through the external fire extinguishing device 11, so as to carry out the fire extinguishing operation. Implementing different fire extinguishing schemes for different areas can effectively improve the fire extinguishing efficiency and accuracy.

[0051] In one of the embodiments, it further includes: a moving unit, installed inside the drone hangar, and both the battery area fire extinguishing device 4 and the circuit area fire extinguishing device 5 are movably installed on the moving unit.

[0052] In this embodiment, the moving unit can be a slide rail arranged inside the drone hangar. Both the battery area fire extinguishing device 4 and the circuit area fire extinguishing device 5 are installed on the slide rail. Under the action of the slide rail, the spraying direction of the nozzle of the fire extinguishing device can be adjusted, thereby improving the fire extinguishing efficiency and accuracy of the fire extinguishing device.

[0053] In other feasible ways, the nozzle is rotatably installed on the fire extinguishing device, and the spraying angle of the nozzle can also be adjusted according to the position of the fire source, further improving the fire extinguishing efficiency and accuracy of the fire extinguishing device.

[0054] In one of the embodiments, it further includes: an isolation module 3, used to isolate the battery in the battery area 2 from the external environment.

[0055] In this embodiment, the isolation module 3 is a box installed in the battery area 2 of the drone hangar. The battery is installed inside the box, and the box is also provided with a closable magnetic fireproof partition; with the cooperation of the box and the magnetic fireproof partition, an independent compartment can be quickly assembled. When a fire occurs in the battery area 2, while activating the battery area fire extinguishing device 4, the isolation module 3 is activated, so that the magnetic fireproof partition cooperates with the box to seal the battery, thereby isolating oxygen to slow down the spread of the fire.

[0056] In one of the embodiments, the fire extinguishing device further includes a temperature reduction device 6, arranged inside the drone hangar, and used to reduce the temperature inside the drone hangar.

[0057] In this embodiment, the cooling device 6 is installed inside the UAV hangar. When a fire occurs in the battery area 2, while activating the fire extinguishing device 4 in the battery area, the isolation module 3 is activated, and at the same time, liquid nitrogen is released into the UAV hangar through the cooling device 6, thereby reducing the temperature inside the UAV hangar and preventing the fire from spreading further.

[0058] In one of the embodiments, it further includes: a communication module for sending a fire situation report to target personnel; the target personnel include at least one of firefighters and UAV hangar management personnel; the fire situation report includes at least one of real-time fire situation data, fire source information, and fire extinguishing plans. By sending the fire situation report to firefighters and UAV hangar management personnel in a timely manner through the communication module, the fire extinguishing personnel can prepare for fire extinguishing work based on the fire situation report, which helps the fire extinguishing personnel to better carry out fire extinguishing operations on the UAV hangar.

[0059] According to an embodiment of the present invention, as Figure 2 shown, on the other hand, a method for preventing fire in a UAV hangar is also provided, including the following steps:

[0060] Step S100: Obtain the real-time fire situation data of the UAV hangar;

[0061] Step S200: Combine the real-time fire situation data with the trained deep learning model to obtain the fire source information inside and outside the UAV hangar, and dynamically plan a fire extinguishing plan according to the fire source information; the fire source information includes the fire source location and the fire source spreading speed;

[0062] Step S300: Control at least one fire extinguishing device to work based on the fire extinguishing plan.

[0063] In this embodiment, by obtaining the environmental information around and inside the UAV hangar in real time, the corresponding fire situation data is generated; then the real-time fire situation data is combined with the trained deep learning model, and the deep learning model predicts the real-time fire situation data to obtain the fire source information inside and outside the UAV hangar, such as the fire source location and the fire source spreading speed, etc.; then a fire extinguishing plan is dynamically planned according to the fire source information. For example, if the fire source is located in the corner of the UAV hangar and the spreading speed is slow, a local fire extinguishing plan will be formulated; if the fire source spreads quickly and over a large area, multiple fire extinguishing devices will be called to work simultaneously. Finally, at least one fire extinguishing device is controlled to work according to the received dynamically planned fire extinguishing plan to complete the fire extinguishing work. The present invention can effectively monitor and handle the fire situation in the UAV hangar, improve the response speed to the UAV hangar early warning, and effectively improve the efficiency and accuracy of the UAV hangar in dealing with the fire situation through dynamic planning of the fire extinguishing plan.

[0064] As Figure 3 shown, in one of the embodiments, step S300 includes the following steps:

[0065] Step S310: In response to the implementation of the fire extinguishing plan in the battery area 2, control the battery area fire extinguishing device 4 and the temperature reduction device 6 to perform their operations, and activate the isolation module 3 to isolate the battery from the external environment.

[0066] Step S320: In response to the implementation of the fire extinguishing plan in the circuit area 1, control the circuit area fire extinguishing device 5 to perform its operation, and cut off the power supply of the drone hangar.

[0067] Step S330: In response to the implementation of the fire extinguishing plan outside the drone hangar, control the external fire extinguishing device 11 to perform its operation to spray water mist on the fire source outside the drone.

[0068] In this embodiment, the battery area fire extinguishing device 4 is arranged near the battery area 2 and on the inner wall of the drone hangar. When the fire extinguishing plan is implemented in the battery area 2, the battery area fire extinguishing device 4 can be activated to spray heptafluoropropane gas into the battery area 2 for fire extinguishing. At the same time, the temperature reduction device 6 and the isolation module 3 are activated. The temperature reduction device 6 releases liquid nitrogen into the drone hangar to lower the temperature inside the drone hangar and prevent the fire from spreading further. And the magnetic fireproof partition cooperates with the box body to seal the battery, thereby isolating oxygen to slow down the spread of the fire.

[0069] The circuit area fire extinguishing device 5 is arranged near the circuit area 1 and on the inner wall of the drone hangar. When the fire extinguishing plan is implemented in the circuit area 1, the circuit area fire extinguishing device 5 can be activated to spray aerosol fire extinguishing agent into the circuit area 1. At the same time, the circuit power supply is cut off to prevent the fire from spreading further while extinguishing the fire.

[0070] The external fire extinguishing device 11 is arranged outside the drone hangar and on the top of the drone hangar. When the fire extinguishing plan is implemented outside the drone hangar, high-pressure water mist can be sprayed around the drone hangar through the external fire extinguishing device 11 for fire extinguishing operations. Implementing different fire extinguishing plans for different areas can effectively improve the fire extinguishing efficiency and accuracy.
