The programs involved or relied on in the following embodiments are all conventional programs or simple programs in the technical field, and those skilled in the art can make conventional choices or adaptive adjustments according to specific application scenarios.

[0024] ​In order to better understand the technical solutions of the present application, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0025] In order to solve the problem that the existing multi-rotor unmanned aerial vehicle practical training platform has single training content, difficulty in deploying faults and cannot effectively quantitative evaluation, see Figure 1 The present example discloses a multi-rotor unmanned aerial vehicle practical training platform, which comprises a deployment and detection platform 1, a flight test platform 2 and an unmanned aerial vehicle 3.

[0026] In the present embodiment, the unmanned aerial vehicle 3 is a multi-rotor unmanned aerial vehicle with an axle distance of 450mm, which comprises a lower center plate arranged at the bottom, and a PCB circuit board is fixedly arranged at the lower center plate. A plurality of hardware lines connected with each hardware of the unmanned aerial vehicle are arranged on the PCB circuit board to ensure that the corresponding hardware is normally powered on. In order to flexibly realize the deployment of various fault conditions of the unmanned aerial vehicle, a hardware line fault breakpoint is arranged in the hardware line corresponding to each hardware of the PCB circuit board in the present example. Thus, the hardware line fault breakpoint makes the line corresponding to the normal work of each hardware unable to conduct, so that the corresponding hardware cannot work normally, that is, a hardware electrical fault occurs. When the corresponding hardware line fault breakpoint is artificially conducted, the hardware line is restored, the corresponding hardware fault is removed, and the corresponding hardware starts to work normally. Therefore, the present example deploys and removes the hardware electrical fault of the unmanned aerial vehicle based on this, so as to flexibly set the hardware electrical fault of the unmanned aerial vehicle and deeply evaluate the maintenance and removal ability of the trainees.

[0027] Specifically, in the present embodiment, the multi-rotor unmanned aerial vehicle practical training platform comprises a deployment and detection platform 1, see Figure 1 The deployment and detection platform 1 comprises a table 11 and a control console 12 arranged at one side of the tabletop 11. In the present embodiment, a fault detection area 121 is arranged at the control console 12, and the fault detection area 121 comprises a line panel corresponding to the printed hardware lines of the unmanned aerial vehicle. A relay interface is arranged at each fault breakpoint position of the PCB board of each hardware line of the panel. The relay interface in the present example comprises a pair of fault removal terminals, each of which corresponds to each hardware line fault breakpoint at the PCB circuit board of the unmanned aerial vehicle. That is, each relay interface is connected in series in the corresponding hardware line of the unmanned aerial vehicle. Thus, through the fault removal terminal, the operator can measure and obtain the electrical data of the corresponding hardware line of the unmanned aerial vehicle at the fault detection area 121, judge the fault condition, and turn on or off to remove the hardware electrical fault. By synchronously amplifying the hardware line fault breakpoint of the unmanned aerial vehicle to the control console through the fault detection area 121, the maintenance operation of the trainees can be greatly facilitated, and the safety risk of the operation can be reduced.

[0028] In addition, in this embodiment, the multi-rotor UAV training platform also includes an assembly and adjustment equipment box for storing UAV parts. Since there are many types of UAV components, in order to facilitate storage and management, the assembly and adjustment equipment box is provided with several storage slots whose outlines match the outlines of the corresponding parts. Thus, the storage slots enable the orderly storage and organization of various UAV parts, while the slots that match the outlines of the corresponding parts limit and hold the parts in place, preventing the parts from getting mixed up when moving the assembly and adjustment equipment box.

[0029] To facilitate the deployment and setup of various hardware electrical fault scenarios, the assembly, inspection, and debugging platform 1 also includes a controller and relays connected to the fault points of various hardware circuits on the UAV. In this embodiment, the controller is specifically an industrial control computer, and the relays are specifically IoT relays. The relays communicate with the industrial control computer to respond to its control commands and adjust their on / off states, thereby disconnecting some hardware circuit fault points and connecting others according to the control commands, thus completing the deployment of corresponding hardware faults on the UAV. Specifically, the industrial control computer includes a relay on / off control module, a relay on / off detection module, an evaluation module, and an attitude parameter detection module. The relay on / off control module can control the on / off state of the relays between the fault points of various hardware circuits on the UAV according to the corresponding human settings based on the maintenance skills assessment requirements, thereby achieving the purpose of deploying hardware electrical faults as needed. The relay on / off detection module is used to determine the trainee's maintenance actions based on the on / off changes of each port of the relay after the relay on / off control module corresponds to a preset hardware electrical fault. The evaluation module compares the relay on / off control data input to the relay on / off control module with the relay on / off detection data output by the relay on / off detection module to determine whether the trainee has reconnected the disconnected relay to eliminate the fault. The evaluation is then quantitatively assessed and recorded based on the number of faults eliminated. In this embodiment, the multi-rotor UAV training platform can also deploy, detect, and eliminate UAV parameter faults. By setting up an attitude parameter detection module, wireless communication between the industrial control computer and the UAV is achieved. This allows for the pre-setting of UAV parameter faults according to the test requirements. After the trainee completes the parameter fault elimination, the platform reads the UAV parameters and compares them with the correct parameters stored in the industrial control computer, thus achieving a quantitative assessment of the parameter fault elimination capability. Furthermore, the assembly, testing, and adjustment platform 1 also includes a display 13, which interacts with the industrial control computer to display fault deployment, operation, and evaluation data. In other embodiments, the display can also meet the display requirements for UAV flight attitude animation simulation based on the attitude parameter detection module.

[0030] In this embodiment, a stable and reliable wired connection is established between the industrial control computer and the relays via a switch. This allows for network command control and reading of the on / off changes of each port of the relays, enabling the deployment, detection, and troubleshooting of hardware electrical faults in the UAV. Furthermore, the industrial control computer uses MAVLINK protocol commands to achieve wireless communication with the UAV, thereby enabling the deployment, inspection, and troubleshooting of UAV parameter faults.

[0031] To assess the pilot's drone operation skills, the multi-rotor drone training platform also includes Flight Test Platform 2. For details, see [link to details]. Figure 1 In this embodiment, the flight test platform 2 includes a base 21 and a protective case 22. The base 21 has a certain height for fixing the protective case 22, and its internal space can also be used to store the drone assembly and adjustment equipment box. The protective case 22 is fixed to the top of the base 21 and is a hollow box structure, with its internal cavity space used to load the drone 3. Considering the differences in the test subjects' ability to operate the drone, in order to avoid damage to the drone caused by improper operation by the test subjects, in this embodiment, a gimbal is provided at the bottom plate of the protective case 22 for connecting the drone and restricting the drone's flight movement space. See details below. Figure 2 The gimbal includes a longitudinal bearing 41, a ball joint 42, a mounting bracket 43, and a socket. The longitudinal bearing 41 is extendable and retractable, and is fixed perpendicularly to the bottom plate of the protective housing at its center. A mounting bracket 43 is located above the longitudinal bearing 41, and is hinged to the longitudinal bearing via the ball joint 42. A socket is provided to match the mounting bracket 43 and is fixed to the bottom surface of the lower center plate of the drone 3. The engagement between the socket and the mounting bracket 43 enables a movable connection between the drone and the gimbal. Thus, the longitudinal extension and retraction of the longitudinal bearing allows for the drone's ascent and descent, and the ball joint 42 allows for the drone's horizontal tilt and rotation. Specifically, in this embodiment, the longitudinal bearing allows for free movement up and down by 40cm, and the ball joint 42 allows for tilting within a horizontal range of ±45° and deflection at a 360° heading angle. Furthermore, through the movable connection between the socket and the card slot, the drone can be relatively fixed at the gimbal of the protective box during flight control evaluation, and the drone can be taken out for actual outdoor flight testing as needed.

[0032] Furthermore, through the wireless communication connection between the industrial control computer and the drone, the real-time flight data of the drone controlled by the test subject is read back based on the attitude parameter detection module of the industrial control computer. This allows for the evaluation of the difference between the actual flight data and the required flight attitude, thereby assessing the trainee's drone control skills. In this embodiment, the industrial control computer also includes a storage unit that can be used to store the drone's real-time flight data and realize 3D synchronous simulation of the drone's flight attitude, enabling the playback of simulated animations based on the stored data.

[0033] In addition, to facilitate the loading and unloading of the drone at the protective box 22, in this embodiment, see... Figure 1 The protective case 22 includes a hatch 221 located on the front side of the case body, which can be closed during UAV flight control testing to ensure the safety of the testing process. Furthermore, to avoid obstructing the test subject's observation of the UAV's real-time flight attitude, the hatch 221 is made of transparent material in this example. In addition, the remaining side panels of the protective case are perforated or transparent panels to increase the amount of light entering the case, while the perforated panels also allow for the circulation of air inside the case.

[0034] Because of hardware circuit faults in the drone's hardware circuitry, the drone is unable to fly. To address this, the multi-rotor drone training platform in this example is also equipped with jumper wires to short-circuit the faulty hardware circuits, thereby restoring the continuity of the drone's hardware circuitry and ensuring the drone's normal operation during flight testing.
