Description

Technical Field

[0001] The present invention relates to the technical field of fire prevention and extinguishment, and particularly to an unmanned aerial vehicle (UAV) fire prevention and extinguishment system and its application. Background Art

[0002] Places prone to fires such as forests and grasslands often need to be patrolled regularly to detect fires in a timely manner and take timely measures to prevent serious consequences caused by fires. In the prior art, manual patrols are usually carried out by forest area and grassland patrol personnel. The patrol routes are relatively fixed, time-consuming, and it is not easy to detect a fire source far from the patrol route in a timely manner. Even if a fire source is detected in a timely manner, there are also problems such as untimely reporting (there may be sections with poor signal on the patrol route, and reporting can only be carried out normally after reaching other positions), so the fire situation may be delayed. Especially in the summer and autumn seasons when fires occur frequently, it is often necessary to increase the patrol frequency, resulting in serious consumption of human and material resources, but there are still situations where fires are missed or delayed, leading to untimely disposal. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides an unmanned aerial vehicle fire prevention and extinguishment system, which solves the problem in the prior art that fire patrols are prone to missed reports or delays in fire situations, resulting in untimely disposal.

[0004] According to an embodiment of the present invention, an unmanned aerial vehicle fire prevention and extinguishment system includes a ground command center and a mobile command center, and the mobile command center and the ground command center are connected by satellite communication; it also includes patrol UAVs communicatively connected to the mobile command center, and a plurality of fire stations fixed around the patrol area. Each fire station is equipped with fire extinguishing UAVs communicatively connected to the ground command center through satellites or the mobile command center; the patrol UAVs carry mobile video monitoring devices, and the fire extinguishing UAVs carry fire extinguishing high-explosive bombs. The mobile command center can stay at certain positions on the patrol route and then take off the patrol UAVs for patrol, greatly improving the patrol efficiency. At the same time, the mobile video monitoring devices on the patrol UAVs can more easily detect the fire source and report it to the mobile command center, and then report it to the ground command center for timely fire situation disposal in the next step, ultimately enabling the fire situation to be disposed of in a timely manner, solving the problem in the prior art that fire patrols are prone to missed reports or delays in fire situations, resulting in untimely disposal.

[0005] Furthermore, the mobile command center is also provided with a tethered UAV communicatively connected thereto, and the tethered UAV is also communicatively connected to the patrol UAVs and the fire extinguishing UAVs.

[0006] Furthermore, the mobile command center is also equipped with a self-organizing network communication base station.

[0007] Further, it also includes a fixed video device fixedly installed at the highest point within the patrol area, and the fixed video device is communicatively connected to the ground command center.

[0008] Further, the ground command center is provided with a fire patrol screen. After the patrol UAV discovers a fire, it sends the information to the mobile command center, and the mobile command center then sends it to the ground command center and is displayed on the fire patrol screen. After the fixed video device discovers a fire, it sends the information to the ground command center and is displayed on the fire patrol screen.

[0009] Further, the ground command center sends an instruction to the fire station closest to the fire source according to the fire situation, and activates the corresponding fire-fighting UAV to perform fire-extinguishing bomb-dropping operations at the fire source.

[0010] According to the embodiment, the application of the above UAV fire prevention and extinguishing system is also provided, which is used for forest fire prevention and extinguishing and grassland fire prevention and extinguishing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By having the mobile command center stay at certain positions on the patrol route and then taking off the patrol UAV for patrol, the patrol efficiency is greatly improved. At the same time, the mobile video monitoring device on the patrol UAV can more easily discover the fire source and report it to the mobile command center, and then report it to the ground command center for timely next-step fire situation handling, ultimately enabling the fire situation to be handled in a timely manner, solving the problem in the prior art that fire patrol is prone to missed fire reports or delays resulting in untimely handling; at the same time, fire stations are set at multiple positions within the patrol area, and the fire-fighting UAVs set in the fire stations take off under the command of the ground command center and reach above the fire source to drop fire-extinguishing high-explosive bombs, which can timely extinguish the fire in the early stage and achieve a better fire-extinguishing effect.

[0015] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0016] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0017] As Figure 1 Shown in Figure 1 or Figure 2, this embodiment provides an unmanned aerial vehicle (UAV) fire prevention and extinguishing system, which can be used for forest fire prevention and extinguishing and grassland fire prevention and extinguishing. The fire prevention and extinguishing system includes a ground command center and a mobile command center. The ground command center is equipped with a fire situation patrol screen for displaying the fire situation. The mobile command center can be a vehicle, with high mobility. The mobile command center and the ground command center are connected through satellite communication. The fire prevention and extinguishing system also includes patrol UAVs that are communicatively connected to the mobile command center. The patrol UAVs can move synchronously with the mobile command center (i.e., the mobility of the drone operator and the patrol UAVs is achieved through vehicle-mounted means), and multiple fire stations are fixed around the patrol area (i.e., the corresponding forest area or grassland). One fire station is set every 5 kilometers in key areas and one fire station is set every 50 kilometers in general areas). Each fire station is equipped with fire extinguishing UAVs that are communicatively connected to the ground command center through satellites or the mobile command center. Correspondingly, a drone operator for the fire extinguishing UAVs is also equipped on the mobile command center. The patrol UAVs are equipped with mobile video monitoring devices. The patrol work is carried out by the cooperation of the mobile video monitoring devices (i.e., mobile high-definition cameras) and the patrol UAVs. In this solution, the mobile command center can stop at certain positions on the patrol route and then take off the patrol UAVs for patrol, which greatly improves the patrol efficiency. At the same time, the mobile video monitoring devices on the patrol UAVs can more easily detect the fire source and report it to the mobile command center, and then report it to the ground command center for timely follow-up fire situation disposal, ultimately enabling the fire situation to be disposed of in a timely manner, solving the problem in the prior art that fire patrols are prone to missed fire reports or delays, resulting in untimely disposal. At the same time, the fire extinguishing UAVs are equipped with fire extinguishing high-explosive bombs. The fire extinguishing UAVs set in the fire stations take off under the command of the ground command center and reach above the fire source to drop the fire extinguishing high-explosive bombs, which can timely extinguish the fire at an early stage and achieve a better fire extinguishing effect.

[0018] Furthermore, the mobile command center is also communicatively connected to a tethered drone, and the tethered drone is also communicatively connected to the patrol drone and the fire-fighting drone. The mobile command center is also equipped with a self-organizing network communication base station, which can be installed on the tethered drone to provide network relay services for the patrol drone and / or the fire-fighting drone to ensure normal communication. The patrol drone, the tethered drone, the self-organizing network communication base station, and related personnel and equipment (such as the pilots of the patrol drone and the fire-fighting drone) can all be carried on the mobile command center (i.e., the vehicle).

[0019] Even further, the fire prevention and extinguishment system further includes a fixed video device fixedly installed at the highest point within the patrol area. The fixed video device is communicatively connected to the ground command center. The fixed video device is a fixed camera fixedly installed at a relatively high position in the middle (or other relatively central positions) within the patrol area. If the height of the fixed camera is insufficient, a high tower can be erected to place it at a higher position for better overlooking the surroundings, promptly detecting a fire and reporting it to the ground command center. Further, a fire patrol screen is set up at the ground command center. After the patrol drone detects a fire, it sends the information to the mobile command center, and then the mobile command center sends it to the ground command center and displays it on the fire patrol screen. After the fixed video device detects a fire, it sends the information to the ground command center and displays it on the fire patrol screen. The ground command center sends an instruction to the fire station closest to the fire source according to the fire situation, activating the corresponding fire-fighting drone to perform fire-extinguishing bombing operations at the fire source. More specifically, the fire situation can also be reported by tourists. In this case, the ground command center dispatches the mobile command center for recheck and patrol to verify the actual situation and the specific location of the fire, so as to further take measures.

[0020] Even further, the ground command center can dispatch multiple mobile command centers according to the situation to conduct synchronous patrols at multiple points on the same patrol route or on multiple patrol routes, further improving the patrol efficiency and correspondingly increasing the efficiency of detecting fires. At the same time, the pilots equipped on the mobile command center can more promptly take off the fire-fighting drones at the fire stations near the fire source, more efficiently achieving the fire extinguishment operation.

[0021] In this solution, the fire-extinguishing high-explosive bomb used adopts a water-based fire extinguishing agent and is vertically and precisely dropped, performing a fixed-height explosion at a certain height above the fire source (such as 10 - 30 meters above the ground). In this way, the fire extinguishing agent can spread obliquely downward, covering a larger fire-extinguishing area and achieving a better fire-extinguishing effect.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
