[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] In order to solve the problem of poor maneuverability of wire-controlled drones due to the restriction of optical fiber by terrain or obstacles, the embodiments of the present application provide a fiber optic relay aircraft, a wire-controlled drone system, a flight control method and a device, aiming to improve the flexibility and communication continuity of wire-controlled drones in complex terrain.

[0039] See Figure 1 , an embodiment of the present application provides a fiber-optic relay aircraft, comprising:

[0040] A connecting device is connected to the optical fiber and is used to lift the optical fiber and suspend it in the air along with the optical fiber relay aircraft.

[0041] In this embodiment, the fiber optic relay aircraft is connected to the optical fiber via a connecting device. As the fiber optic relay aircraft takes off, the optical fiber will be lifted into the air along with the connecting device. When the fiber optic relay aircraft hovers in the air, the optical fiber will also be suspended in the air. The fiber optic relay aircraft can adjust the lifting position and hovering height of the optical fiber by adjusting its hovering position and hovering height.

[0042] It should be understood that the hovering position of the fiber-optic relay aircraft can be set and adjusted based on the flight conditions of the fly-by-wire drone. The hovering altitude can be dynamically adjusted based on the fly-by-wire drone's mission environment, typically set above the highest obstacle in the area to ensure that the optical fiber does not come into contact with any ground objects. For example, when flying in a forested area, the fiber-optic relay aircraft can rise above the treetops to prevent the optical fiber from becoming entangled in branches; in an urban environment, it can rise above the rooftops of buildings to ensure an unobstructed optical fiber transmission path.

[0043] Optionally, in some embodiments, the fiber-optic relay aircraft further includes a flight control device, and the flight control device is used to control the second flight state of the fiber-optic relay aircraft based on the first flight state of the wire-controlled UAV.

[0044] It should be understood that in this embodiment, the fiber-optic relay aircraft can achieve coordinated flight with the wire-controlled drone through the flight control device. When the wire-controlled drone performs its mission, the fiber-optic relay aircraft flies in coordination with the wire-controlled drone, thereby adjusting the position of the optical fiber in real time to ensure the stability of the fiber-optic communication.

[0045] Optionally, in some embodiments, the optical fiber relay aircraft further comprises:

[0046] A winding device is used to wind the optical fiber to adjust the length of the optical fiber between the wire-controlled drone and the optical fiber relay aircraft.

[0047] During the mission execution phase, the fiber optic relay aircraft can wind the optical fiber through the winding equipment according to the flight speed and position of the wire-controlled drone, realize dynamic adjustment of the optical fiber length, and ensure the tightness and safety of the optical fiber.

[0048] At the end of the mission and during the recovery phase, the optical fiber is wound using winding equipment to ensure its safe recovery after the mission is complete, preventing the optical fiber from being pulled or damaged during landing, and ensuring the integrity and reliability of the entire mission execution chain.

[0049] It should be understood that the winding device can wind the optical fiber, thereby adjusting the length of the optical fiber between the wire-controlled drone and the fiber-optic relay aircraft. The specific structure of the winding device is not limited herein. Specifically, the winding speed of the winding device is adjustable, and the degree and direction of winding of the optical fiber by the winding device can also be set and adjusted according to actual conditions.

[0050] Optionally, in some embodiments, the fiber-optic relay aircraft further includes: a sensing device and a flight control device, the sensing device is connected to the flight control device, the sensing device is used to obtain obstacle information, and the flight control device is used to adjust the hovering position of the fiber-optic relay aircraft based on the obstacle information.

[0051] It should be understood that the sensing equipment is used to monitor obstacles within the drone's flight area in real time. By transmitting obstacle information to the flight control device, the fiber-optic relay aircraft's hovering position can be automatically adjusted based on this information, ensuring smooth fiber-optic communication and a safe transmission path. For example, when a fly-by-wire drone flies over a hill, the relay aircraft will monitor the current environment and automatically increase its hovering altitude based on the height of obstacles in the surrounding environment to avoid obstruction of the fiber by trees or buildings on the hillside.

[0052] Optionally, in some embodiments, the fiber-optic relay aircraft utilizes a lightweight design and a high-efficiency battery system to enable the fiber-optic relay aircraft to hover stably for extended periods of time. Specifically, in some embodiments, the fiber-optic relay aircraft also includes an external energy supply device, such as a solar panel. The external energy supply device is used to supply energy to the fiber-optic relay aircraft, thereby extending its flight time and further ensuring the smooth execution of long-duration, controlled-by-wire drone missions.

[0053] Optionally, in some embodiments, to optimize energy usage, the fiber-optic relay aircraft enters a low-power mode when not in a hovering state, minimizing energy consumption in the standby state. This configuration enables the fiber-optic relay aircraft to hover for extended periods, further improving its endurance.

[0054] In an embodiment of the present application, by cooperating with a fiber-optic relay aircraft and a wire-controlled drone, the optical fiber can be lifted and hovered in the air, preventing the optical fiber from being entangled by ground obstacles and affecting normal communication, thereby improving the flexibility and communication continuity of the wire-controlled drone in complex terrain.

[0055] like Figure 2 As shown, the embodiment of the present application also provides a wire-controlled drone system, including:

[0056] The wire-controlled UAV and the above-mentioned optical fiber relay aircraft are connected via optical fiber.

[0057] It should be understood that a wire-controlled drone is responsible for executing its mission and transmitting signals to the ground or command center via optical fiber. These drones offer the advantages of strong anti-interference capabilities, high bandwidth, and low latency. Firstly, because optical fiber transmission is not restricted by the radio spectrum, it effectively avoids enemy electronic interference, ensuring stable operation of wire-controlled drones in complex electromagnetic environments. Secondly, optical fiber transmission offers higher data bandwidth and lower latency, making it particularly suitable for high-quality video backhaul and the transmission of precise control signals.

[0058] However, the flight range of a wire-controlled drone is limited by the length of the optical fiber. Especially in complex terrain, the optical fiber can easily become entangled with obstacles on the ground (such as buildings, trees, rocks, etc.), resulting in obstruction of the flight path and even damage to the optical fiber. In order to overcome the above-mentioned problem of optical fiber limitations in wire-controlled drones, a fiber-optic relay aircraft is introduced into the wire-controlled drone system provided in this embodiment. The fiber-optic relay aircraft is used to lift the optical fiber to a preset position in the air and hover it, so that the optical fiber maintains a safe distance from ground obstacles, thereby avoiding entanglement or obstruction of the optical fiber, ensuring a smooth flight path for the wire-controlled drone, and also providing a certain degree of protection for the optical fiber to prevent damage to the optical fiber.

[0059] The fly-by-wire drone system provided in the embodiments of this application incorporates a fiber-optic relay aircraft. First, the fiber-optic relay aircraft lifts the optical fiber into the air, preventing it from being affected by ground obstacles, thereby enabling the fly-by-wire drone to fly flexibly in complex environments. Second, by lifting the optical fiber into the air, the friction and damage risk between the optical fiber and obstacles are reduced, extending the service life of the optical fiber. Third, the design of the fiber-optic relay aircraft increases the effective control radius of the fly-by-wire drone, expanding the mission range of the fly-by-wire drone.

[0060] like Figure 3 As shown, the embodiment of the present application also provides a flight control method, which specifically includes the following steps:

[0061] Step 301, obtaining a first flight state of the wire-controlled UAV;

[0062] Step 302: Control a second flight state of the fiber optic relay aircraft based on the first flight state.

[0063] It should be understood that the control method of the fiber-optic relay aircraft provided in the embodiments of the present application can be used to control the fiber-optic relay aircraft in the above-mentioned wire-controlled drone system.

[0064] As an optional embodiment, the fiber-optic relay aircraft includes a flight control device, which is used to execute the above-mentioned flight control method. In this embodiment, the flight control device is built into the fiber-optic relay aircraft and is a module in the fiber-optic relay aircraft.

[0065] As another optional implementation, an embodiment of the present invention further provides a flight control device for executing the flight control method provided in an embodiment of the present application, wherein the flight control device is communicatively connected to both the fiber-optic relay aircraft and the wire-controlled drone.

[0066] Optionally, in some embodiments, step 302 includes:

[0067] When the first flight state indicates that the wire-controlled UAV is in a take-off state, the optical fiber relay aircraft is controlled to take off, and the optical fiber is lifted to a preset position and hovered in the air.

[0068] In some embodiments, when the wire-controlled drone takes off, the fiber-optic relay aircraft takes off simultaneously with the wire-controlled drone, raising the optical fiber to a preset position and hovering in the air. In other embodiments, the fiber-optic relay aircraft has the ability to take off vertically. When the wire-controlled drone takes off, the fiber-optic relay aircraft is controlled to take off vertically and quickly rise to a preset height, reach a preset position, and then hover stably at the preset position.

[0069] It should be understood that during the takeoff phase, a fiber optic connection has been established between the wire-controlled UAV and the fiber optic relay aircraft to ensure the reliability of signal transmission and to ensure that the fiber optic relay aircraft can obtain the flight status of the wire-controlled UAV in real time.

[0070] In this embodiment, when the first flight state represents that the wire-controlled UAV is in the take-off state, the second flight state of the fiber-optic relay aircraft is also controlled to be the take-off state, thereby realizing the coordinated flight of the fiber-optic relay aircraft and the wire-controlled UAV, so that the optical fiber can be lifted to a preset position and hover in the air, ensuring normal communication of the wire-controlled UAV.

[0071] Optionally, in some embodiments, step 302 includes:

[0072] When the first flight state indicates that the wire-controlled UAV is in a mission completion state, the optical fiber relay aircraft is controlled to wind the optical fiber to a preset position.

[0073] In some embodiments, when the wire-controlled drone completes its mission, the fiber optic relay aircraft reels the optical fiber to a safe location (i.e., a preset location) to ensure the integrity of the optical fiber and reduce the probability of damage. In other embodiments, when the first flight state indicates that the wire-controlled drone has completed its mission, the fiber optic relay aircraft slowly descends at a preset speed, reels the optical fiber to a safe location, and waits for the wire-controlled drone to land with it. It should be understood that the preset location is not limited herein.

[0074] In this embodiment, when the first flight state indicates that the controlled-by-wire drone has completed its mission, the second flight state of the fiber-optic relay aircraft is also mission-complete, thereby achieving coordinated flight between the fiber-optic relay aircraft and the controlled-by-wire drone. In this state, the fiber-optic relay aircraft winds the optical fiber, ensuring a smooth and orderly fiber retrieval process while ensuring the integrity of the fiber and reducing the probability of damage during descent.

[0075] Optionally, in some embodiments, the method further comprises:

[0076] Acquiring operating data of the wire-controlled drone, the operating data including position information and / or flight speed;

[0077] The optical fiber is wound based on the operating data to adjust the length of the optical fiber between the wire-controlled drone and the optical fiber relay aircraft.

[0078] It should be understood that during flight, the fiber-optic relay aircraft and the controlled-by-wire drone fly in tandem, transmitting data via optical fiber. The fiber-optic relay aircraft can obtain the controlled-by-wire drone's operational data, including its position and / or flight speed. It then uses its own position information to determine the relative position of the controlled-by-wire drone and the fiber-optic relay aircraft. Based on this relative position information, the relay aircraft can flexibly adjust the length and tightness of the optical fiber to ensure the safety of the optical fiber transmission line.

[0079] In a specific implementation, the fiber optic winding can be performed by the winding equipment of the fiber optic relay aircraft. In some embodiments, the fiber optic relay aircraft is also equipped with an automatic winding and tension control system that can automatically adjust the length and tension of the fiber optic according to the position of the wire-controlled drone, ensuring that the fiber neither drags on the ground nor is overly tense.

[0080] In this embodiment, the fiber optic relay aircraft can automatically wind the optical fiber based on the position information and / or flight speed of the wire-controlled drone, thereby adjusting the length of the optical fiber between the wire-controlled drone and the fiber optic relay aircraft to ensure the tightness and safety of the optical fiber.

[0081] Optionally, in some embodiments, the method further comprises:

[0082] Obtain obstacle information;

[0083] The hovering height of the fiber optic relay aircraft is adjusted based on the obstacle information.

[0084] In some embodiments, when a wire-controlled drone performs a mission, the fiber optic relay aircraft always maintains a certain height above the drone, obtains obstacle information in real time, adjusts its own position and height according to the obstacle information, avoids interference from ground obstacles, and ensures smooth fiber optic communication.

[0085] In a specific implementation, the obstacle information can be acquired based on the sensor equipment of the optical fiber relay aircraft.

[0086] In this embodiment, the fiber-optic relay aircraft has obstacle detection and avoidance capabilities. Upon detecting a potential fiber entanglement risk, the fiber-optic relay aircraft automatically adjusts its hovering position and altitude to avoid fiber obstruction. This configuration enables the fly-by-wire drone system to dynamically adapt to complex terrain, varying altitudes, and varying obstacles, enabling flexible operation in a variety of environments.

[0087] In an embodiment of the present application, the fiber optic relay aircraft is controlled by a control method of a fiber optic relay aircraft, so that the fiber optic relay aircraft works in coordination with the wire-controlled drone throughout the entire process. During the take-off phase of the wire-controlled drone, the fiber optic relay aircraft takes off synchronously with the wire-controlled drone, lifts the optical fiber to a preset position and hovers under control to prevent the optical fiber from being interfered with by ground obstacles. During the mission execution phase of the wire-controlled drone, the fiber optic relay aircraft dynamically adjusts the hovering height according to the flight environment of the drone to adapt to the changes in the flight path of the wire-controlled drone, ensuring the continuity and stability of the optical fiber transmission, and at the same time adjusts the length of the optical fiber by winding the optical fiber to ensure that the optical fiber neither drags on the ground nor is it overly tight. During the mission completion phase of the wire-controlled drone, the fiber optic relay aircraft autonomously lowers the hovering height and automatically winds the optical fiber to achieve synchronous landing and optical fiber protection with the wire-controlled drone, preventing the optical fiber from being pulled or damaged during landing, and ensuring the integrity and reliability of the entire mission execution chain.
