[0031] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a safety protection device for drone control training, which can effectively prevent the user from damaging the drone due to improper operation, misoperation or dangerous operation, thereby effectively protecting the drone during training.

[0034] Specifically, the safety protection device for drone control training includes a drone body, a processor 11, a first positioning device 12, a distance measuring device 13, a flight control interface 14, a wireless interface 15, and a configuration port 16. The processor 11, the first positioning device 12, the distance measuring device 13, the flight control interface 14, the wireless interface 15, and the configuration port 16 are all provided on the drone body.

[0035] The drone body is training at a training ground 4. The processor 11 is disposed on the drone body. The first positioning device 12 is disposed on the drone body and connected to the processor 11. The first positioning device 12 is configured to obtain spatial position information of the drone body and transmit the spatial position information of the drone body to the processor 11.

[0036] It should be noted that the first positioning device 12 is used to obtain the drone's current three-dimensional spatial position information in real time. By comparing the drone's spatial position information with the flight field's position information, the processor 11 can determine the drone's current relative distances dx, dy, and dz from the edge of the training field 4 and the ground. The difference between the current and previous positions can then be used to calculate the drone's real-time flight speed V, decomposing the speed into its x-, y-, and z-axis components Vx, Vy, and Vz.

[0037] The distance measuring device 13 is connected to the processor 11 , and is used to obtain the distance between the drone body and the obstacle, and send the distance to the processor 11 .

[0038] In this embodiment, the distance measuring device 13 is used to actively measure the distance between the drone and the obstacle in real time, and send the distance to the processor 11, which then makes a judgment and makes corresponding control.

[0039] The flight control device 2 is connected to the processor 11 via the flight control interface 14 , and the flight control device 2 is used to receive control instructions from the processor 11 to control the flight of the UAV body.

[0040] In this embodiment, the flight control device 2 is used to receive the control instructions calculated by the processor 11 and control the flight of the UAV.

[0041] The wireless receiver 3 is connected to the processor 11 via the wireless interface 15 . The wireless receiver 3 is used to receive control instructions from the user and send the control instructions to the processor 11 for analysis.

[0042] The human-machine interface unit is connected to the processor 11 via the configuration port 16 . The human-machine interface unit is used to input preset instructions of the user and send the preset instructions to the processor 11 .

[0043] In this embodiment, the user can input information related to the training area 4 and its control through the human-machine interface unit. For example, the user can set the spatial coordinates of the training area 4, the spatial coordinates of the flight area 41 and the restricted area 42, and the upper limit of the drone's flight speed within the restricted area 42 and the upper limit of the drone's flight speed within the flight area 41. The relevant information is then input into the processor 11 through the configuration interface.

[0044] The processor 11 performs the first processing or the second processing on the control instruction according to the spatial position information of the drone body, the distance and the preset instruction, and then sends the control instruction to the flight control device 2.

[0045] In this embodiment, the processor 11 is the control core of the safety protection device 1, responsible for continuously reading and recording the drone's spatial position information, calculating the drone's flight speed and its distance from the edge of the control area and the ground, and interpreting user control commands via the wireless interface 15. When the drone is flying within the flight area 41 and its flight speed does not reach the preset flight limit, the processor 11 does not limit the drone's flight speed. This is the first processing performed by the processor 11 on the control commands. Simultaneously, the processor 11 directly transmits the user's control commands sent by the wireless receiver 3 to the flight control device 2, which then controls the drone's flight. When the drone's flight speed within the flight area 41 exceeds the preset flight limit, the processor 11 modifies the user's control commands sent by the wireless receiver 3. This is the second processing performed by the processor 11 on the control commands, thereby limiting the drone's flight speed. In particular, when the distance from the drone to a preceding obstacle measured by the ranging device 13 reaches the limit, the drone is controlled to decelerate.

[0046] The safety protection device for drone control training provided in this embodiment has a reasonable structural design and limits the flight of the drone to the range of the training ground 4. When the user issues an instruction for a dangerous operation, the safety protection device 1 can adjust the control instruction of the drone and control the drone to avoid the occurrence of danger, thereby being able to protect the drone well.

[0047] The safety protection device for drone control training can avoid the problem of drone damage caused by improper operation of the user. Users can conduct drone control training independently, which effectively improves training efficiency.

[0048] Optionally, a second positioning device 5 is further included, and the second positioning device 5 is arranged on the training ground 4, so that the second positioning device 5 can locate the training ground.

[0049] Optionally, the number of the second positioning devices 5 is one or more, which enables the positioning device 12 to quickly and accurately locate the training ground.

[0050] Optionally, a plurality of positioning devices 12 are arranged at intervals on the training ground 4. By using a plurality of positioning devices 12 at different positions, the ground can be accurately positioned, which facilitates the controller to control the drone and effectively prevents the drone from flying out of the training ground during training.

[0051] Optionally, the training ground 4 includes a flight area 41 and a restricted area 42, wherein the restricted area 42 surrounds the flight area 41. This allows the flight process of the drone to be better controlled and can further prevent damage to the drone due to misoperation.

[0052] In this embodiment, when the drone is flying, the spatial range in which the drone is able to fly is the spatial range included in the training ground 4. One or more positioning devices 12 need to be set up in the training ground 4, or the precise geographical location coordinate information of the training ground 4 needs to be known so that the controller can control the drone. The area within a certain range from the edge of the training ground 4 is the restricted area 42. The speed of the drone in the restricted area 42 is constrained by the safety protection device 1. The closer the drone is to the edge of the training ground 4, the slower the flight speed of the drone, until the flight speed of the drone is reduced to 0. The central area of ​​the training ground 4 surrounded by the restricted area 42 is the free flight area of ​​the drone. When the drone flies in the free flight area 41, if its flight speed does not exceed the preset speed upper limit, the drone is only controlled by the wireless receiver 3.

[0053] Optionally, a power module 17 is further included, and the power module 17 includes a battery, which supplies power to the safety protection device 1. The battery is installed in the drone body, and the safety protection device 1 is powered by the power module 17 to ensure that the drone is protected by the safety protection device 1 during flight.

[0054] Optionally, the first positioning device 12 is a GPS positioning module, a Beidou positioning module or an RTK positioning module, which enables the first positioning device 12 to quickly and accurately locate the UAV.

[0055] In addition, the first positioning device 12 may also be a GLONASS module, a Galileo satellite positioning module, etc. Of course, the second positioning device 5 may also be a GPS positioning module, a Beidou positioning module or an RTK positioning module, a GLONASS module, a Galileo satellite positioning module, etc., which enables the second positioning device 5 to quickly and accurately locate the training ground.

[0056] Optionally, the distance measuring device 13 is an infrared rangefinder, an ultrasonic rangefinder or a laser rangefinder. This enables the distance measuring device 13 to accurately measure the distance between the drone and the edge of the training ground 4, obstacles and the ground.

[0057] Optionally, the processor 11 is a single chip microcomputer, ARM, FPGA, DSP or Raspberry Pi. This enables the controller to effectively control the flight state of the drone.

[0058] In this embodiment, the safety protection device is installed between the wireless receiver 3 and the flight control device 2 of the drone, and is used to intercept the user's control instructions output by the wireless receiver 3, and the processor 11 determines whether to modify the control instructions according to the current flight status of the drone. Among them, the configuration port 16 can be implemented by a universal communication interface such as a serial port, a USB interface, a Can interface, a network port, etc. Before the control training, the safety protection device 1 is connected to a computer equipped with a human-machine interface unit through the configuration port 16. Through the human-machine interface unit, the spatial position coordinates of the training ground 4 are set, the spatial position coordinates of the restricted area 42 or the distance between the restricted area 42 and the edge of the training ground 4 (called the restricted width) are set, and the upper limit value of the flight speed of the drone is set.

[0059] During control training, processor 11 reads and records the drone's current position every 0.01 seconds, comparing it with the drone's previous position to calculate the drone's current flight speed. By comparing the drone's current position with the coordinates of training ground 4, it determines whether the drone is in flight area 41 or restricted area 42. When the drone is flying within flight area 41 and at a normal speed, processor 11 does not modify the user control signal output by wireless receiver 3, but directly transmits the user's control command to the drone's flight control unit 2, ensuring that the drone maintains its original operating mode.

[0060] In this embodiment, when the UAV's flight speed exceeds a preset flight upper limit, the processor 11 limits the UAV's flight speed to the preset flight upper limit. When the UAV enters the restricted area 42, the processor 11 controls the UAV to decelerate.

[0061] One implementation method is that when the drone enters the restricted area 42, the controller can only issue a command to fly in a direction away from the edge of the training ground 4, and is not allowed to continue to issue a command to fly toward the edge of the training ground 4, thereby causing the drone to exit the restricted area 42.

[0062] Another solution is to proportionally reduce the upper limit of the drone's flight speed within restricted area 42. For example, if restricted area 42 is 10 meters wide and the drone is 9 meters from the edge of training ground 4, the upper limit of the drone's speed is reduced to 0.9 times the original upper limit. When the drone is 2 meters from the edge of training ground 4, the upper limit of the drone's speed is reduced to 0.2 times the original upper limit, ultimately forcing the drone to make an emergency landing.

[0063] It's important to note that restricted area 42 acts as a buffer and protection for the boundaries of training ground 4. Due to the high speed and high inertia of drones, to prevent dangerous situations like collisions with walls, restricted area 42 should be set to a sufficient distance for the drone to decelerate. On the other hand, if restricted area 42 is too large, flight area 41 will be too small, limiting the drone training experience. Therefore, it's important to divide the area appropriately and set an appropriate speed limit based on actual conditions.

[0064] In one embodiment, the distance measuring device 13 is always pointed at the flight direction of the drone, and measures the distance to the obstacle in front of the flight direction in real time. When it is found that the distance to the obstacle in front (such as a flagpole in a square) reaches a limit width, the processor 11 controls the drone to slow down.

[0065] In another embodiment, the ranging device 13 detects the distance between the drone and obstacles within a 360-degree range around the drone in real time, and records the distance and direction of the obstacles in the processor 11. When the drone approaches the obstacle and reaches a limited width range, the drone is controlled to slow down, even if a head-on collision is not imminent, thereby preventing the drone from colliding with the obstacle when turning.

[0066] In addition, the safety protection device for drone control training can be used not only for regular student training, but also for different scenarios such as model aircraft performances, competitions, and examinations.

[0067] The safety protection device for drone control training provided in this embodiment has a reasonable structural design, can avoid damage to the drone due to improper operation by the user, and greatly improve training efficiency.

[0068] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
