The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM), and can also be a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 can also be an independent storage device from the aforementioned processor 1001.

[0051] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the flight control module, and can include more or fewer components than the figure, or combine certain components, or different component arrangements.

[0052] As Figure 1 shown, the memory 1005 as a storage medium can include an operating system, a network communication module, a user interface module, and a flight control device adjustment program.

[0053] In Figure 1 the flight control module shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the flight control module of the application can be arranged in the flight control module, and the flight control module calls the flight control device adjustment program stored in the memory 1005 through the processor 1001, and executes the flight control device adjustment method provided by the embodiment of the application.

[0054] The embodiment of the application provides a flight control device adjustment method, referring to Figure 2 , Figure 2 is a flowchart of the first embodiment of the flight control device adjustment method of the application.

[0055] The adjustment method of the flight control device is applied to a flight control module, the flight control module is connected with an actuation module in a control device, and the control device comprises a control lever, a rotating mechanism, the actuation module connected in sequence, and a damper connected with the rotating mechanism.

[0056] The adjustment method of the flight control device comprises the following steps.

[0057] In step S10, a corresponding actuation torque is determined according to a current flight control mode.

[0058] It can be understood that the flight control module and the control device in the embodiment are installed on a flight vehicle, which can be a drone, a flying car, an airplane, etc. The embodiment is described by taking a rotary-wing flying car as an example. Optionally, the flight control module in the embodiment is integrated with a driving module. Optionally, the flight control module in the embodiment is connected with the actuation module through the driving module, and the driving module is used to drive the actuation module. The communication form between the flight control module and the actuation module is not limited in the embodiment.

[0059] It should be noted that the flight vehicle has multiple flight control modes, and the control objects of the control device and the types of control levers used are different in different flight control modes. Optionally, the flight control modes in the embodiment include but are not limited to an attitude control mode, a constant-height mode, and a constant-point hovering mode. Most current multi-rotor flight vehicles use double-lever control, and the two control levers correspond to the pitch control, roll control, yaw control, and throttle control of the flight vehicle respectively. The control lever in the embodiment includes but is not limited to a throttle lever. Taking a throttle rocker as an example, in the attitude control mode, the control object of the throttle rocker is the propeller speed, and the displacement of the throttle lever is mapped to the propeller speed of the flight vehicle, and the speed increases with the increase of the displacement of the throttle lever; in the constant-height mode and the constant-point hovering mode, the control object of the throttle rocker is the vertical speed, and the displacement of the throttle lever is mapped to the vertical speed of the flight vehicle. The constant-height mode and the constant-point hovering mode are suitable for centering rockers, and the attitude control mode is suitable for no-lever-force rockers.

[0060] It should be understood that the actuation torque corresponding to different flight control modes is different. Optionally, in the attitude control mode, the actuation torque is 0, and in the constant-height mode and the constant-point hovering mode, the actuation torque is related to the current displacement of the control lever. In a specific implementation, a theoretical displacement-torque curve in the constant-height mode and the constant-point hovering mode is constructed in advance, the corresponding actuation torque is found from the displacement-torque curve according to the current displacement of the control lever, the torque corresponding to the midpoint of the displacement stroke of the control lever in the displacement-torque curve is 0, and the torque at the highest and lowest limit positions is the largest.

[0061] Step S20: controlling the actuating module according to the actuating torque, so that the actuating module adjusts the position of the control stick through the rotating mechanism.

[0062] It should be noted that, in one implementation, the control actuating module outputs the actuating torque to overcome the movement resistance provided by the damper, drives the control stick to rotate through the rotating mechanism, and rotates to the neutral position of the control stick displacement stroke, so that the type of the control stick is switched to a centering rocker; in another implementation, the actuating torque is 0, the actuating module does not output torque, and the control stick remains unchanged under the damping action of the damper, so that the type of the control stick is switched to a no-rod-force rocker.

[0063] The method of the embodiment is described below in combination with examples:

[0064] When the driver pulls the throttle control stick, the control stick rotates around the rotating mechanism, drives the actuating module to rotate, generates a rotary displacement, and a displacement sensor integrated in the actuating module detects the change in the displacement of the control stick and sends the current displacement of the throttle control stick to the flight control computer as a throttle control instruction.

[0065] When in the constant-height mode or the point-hold mode, the flight control computer controls the actuating module to output a control torque according to the current displacement of the throttle control stick and continuously provides a linear control stick force characteristic.

[0066] When in the attitude control mode, the flight control computer outputs an instruction of 0 torque to control the actuating module to be powered off, at this time, the throttle control stick is a no-rod-force rocker, and only the damper provides a damping action, and the damping force linearly changes with the control speed of the throttle control stick.

[0067] The adjustment method of the flight control device provided in the embodiment is applied to a flight control module, the flight control module is connected with an actuating module in the control device, the control device comprises, in sequence, a control stick, a rotating mechanism, the actuating module, and a damper connected with the rotating mechanism, and the method comprises the following steps: determining a corresponding actuating torque according to a current flight control mode; and controlling the actuating module according to the actuating torque, so that the actuating module adjusts the position of the control stick through the rotating mechanism. In the foregoing manner, the actuating torque is determined according to the flight control mode, the actuating module is used to provide a control stick force for the control stick, the control stick can be flexibly adapted to different flight control modes, the type of the control stick can be switched to a centering rocker or a no-rod-force rocker through the actuating module and the damper, the flight control data is prevented from instantaneously changing due to the mismatch between the type of the control stick and the mode requirement, and the stability and safety of the aircraft are improved.

[0068] Reference Figure 3 , Figure 3Flowchart of the second embodiment of the adjusting method of the flight control device.

[0069] Based on the first embodiment, the flight control device further comprises a displacement sensor in the adjusting method of the flight control device.

[0070] The step S10 comprises:

[0071] Step S101: determining the displacement and torque curve corresponding to the first mode when the current flight control mode is the first mode.

[0072] It should be understood that the first mode is a flight control mode suitable for a centering rocker. Assuming that the control stick is a throttle control stick, the flight control mode comprises an attitude control mode, a constant height mode and a point hovering mode, and the first mode is the constant height mode or the point hovering mode. The theoretical displacement and torque curves in different flight control modes are stored in advance. In the displacement and torque curve, the torque corresponding to the midpoint of the control stick displacement stroke is 0, and the torque of the highest and lowest limit positions is the largest.

[0073] Step S102: obtaining the current control stick displacement fed back by the displacement sensor, and determining the actuating torque corresponding to the current control stick displacement according to the displacement and torque curve.

[0074] It should be noted that the displacement sensor is integrated in the actuating module. When the pilot pulls the control stick, the control stick will rotate around the rotating mechanism, drive the rotating module to rotate, generate a rotating displacement, and the displacement sensor detects the change in the control stick displacement, sends the current control stick displacement to the flight control module, and the flight control module queries the actuating torque corresponding to the current control stick displacement according to the displacement and torque curve corresponding to the first mode. The actuating module outputs the actuating torque to continuously provide a linear control stick force characteristic, and at the same time, the control stick will drive the damper to stretch or compress axially, and the damper movement generates a damping force to provide a suitable damping force feeling for the pilot, and the damping force increases linearly with the increase of the control speed.

[0075] Further, in order to avoid the instantaneous mutation of the flight control data when the mode is switched, the adjusting method of the flight control device further comprises: obtaining the current displacement fed back by the displacement sensor when the current flight control mode is switched from the second mode to the first mode; controlling the actuating module to power on according to the first mode switching information; and controlling the actuating module to drive the control stick to move from the current displacement to the neutral position according to the displacement and torque curve corresponding to the first mode.

[0076] It should be understood that the second mode is a flight control mode suitable for a no-rod-force rocker. Assuming that the control lever is a throttle control lever, the flight control mode includes an attitude control mode, a constant height mode, and a point hovering mode, and the second mode is the attitude control mode. When the attitude control mode is switched to the constant height mode or the point hovering mode, the flight control module sends a mode switching instruction, a throttle lever displacement, and a control force to the driving module, the driving module drives the actuator module to be powered on, instantaneously moves to the neutral position of the throttle lever, and outputs the control force in real time according to the current displacement. By the above-mentioned mode, the flight control data of the aircraft is prevented from instantaneously changing, and the stability and safety of the aircraft are improved.

[0077] It should be noted that the first mode switching information is a mode switching instruction generated when the second mode is switched to the first mode, the actuator module is controlled to be powered on according to the mode switching instruction, and the actuation torque output by the actuator module in real time is controlled according to the displacement and torque curve, so that the control lever is driven to move from the current displacement at the time of switching to the neutral position of the control lever displacement stroke.

[0078] In the embodiment, when the current flight control mode is the first mode, the displacement and torque curve corresponding to the first mode is determined, the current control lever displacement fed back by the displacement sensor is obtained, and the actuation torque corresponding to the current control lever displacement is determined according to the displacement and torque curve. By the above-mentioned mode, the flight control module controls the actuator module to output different actuation torques according to different displacements, provides appropriate lever force characteristics, actively controls the movement of the control lever in the first mode, realizes the type switching of the control lever to a return-to-center rocker, and makes the control lever adapt to the flight control mode of the first mode.

[0079] Reference Figure 4 , Figure 4 The flowchart of the adjusting method of the flight control device is shown in the third embodiment of the adjusting method of the flight control device.

[0080] Based on the first embodiment, in the adjusting method of the flight control device, the step S10 includes the following steps.

[0081] In the step S103, when the current flight control mode is the second mode, the corresponding actuation torque is a preset value.

[0082] It should be understood that the second mode is a flight control mode suitable for a no-rod-force rocker. Assuming that the control lever is a throttle control lever, the flight control mode includes an attitude control mode, a constant height mode, and a point hovering mode, and the second mode is the attitude control mode. The preset value can be 0, and can also be other single marker values for representing power-off, for example, the preset value is 10000, it is agreed in advance that the actuation torque corresponding to the second mode is 10000, and the value 10000 is used to represent the control of the actuator module to be powered off.

[0083] The step S20 includes the following steps.

[0084] Step S201: controlling the actuation module to be powered off according to the preset actuation torque.

[0085] It should be noted that when in the attitude control mode, the flight control module outputs an instruction of a preset torque, and the driving module controls the actuation module to be powered off after receiving the instruction. At this time, the control stick is a stickless force stick, and only the damper provides damping action, and the damping force linearly changes with the operating speed of the throttle lever.

[0086] Further, in order to avoid the instantaneous mutation of the flight control data when the mode is switched, the adjusting method of the flight control device further comprises: when the current flight control mode is switched from the first mode to the second mode, solving the corresponding control displacement of the control device according to the control law of the second mode; controlling the actuation module to drive the control stick to move to the control displacement; and controlling the actuation module to be powered off according to the second mode switching information.

[0087] It should be understood that the first mode is a flight control mode suitable for a centered stick. Assuming that the control stick is a throttle control stick, the flight control mode includes an attitude control mode, a constant height mode and a constant point hovering mode, and the first mode is the constant height mode or the constant point hovering mode. When the flight control mode is switched from the constant height mode or the constant point hovering mode to the attitude control mode, the flight control module records the motor speed of the propeller at the current time, the control law describes the functional relationship between the controlled state variable and the system input signal, the motor speed of the propeller corresponding to the throttle lever control displacement is inversely solved according to the control law of the attitude control mode, the flight control module sends the mode switching instruction and the throttle lever control displacement to the driving module, the actuation module is controlled to drive the control stick to instantaneously move to the corresponding control displacement, the second mode switching information is the mode switching instruction generated when the first mode is switched to the second mode, the actuation module is controlled to be powered off according to the mode switching instruction, and the type of the control stick is switched to a stickless force stick. The transition process proposed in this embodiment eliminates the sudden change of the propeller speed and the tension caused by the sudden change of the rod amount of the throttle control stick, maintains the height stability of the aircraft, helps to reduce the height drop accident, and improves the stability and safety of the aircraft.

[0088] In the embodiment, when the current flight control mode is the second mode, the corresponding actuation torque is determined to be a preset value, and the actuation module is controlled to be powered off according to the preset actuation torque. In the second mode, the actuation module is controlled to be powered off, the type of the control stick is switched to a stickless force stick, and the control stick can adapt to the flight control mode of the second mode.

[0089] Referring to Figure 5 , Figure 5 is a structural block diagram of the adjusting system of the first embodiment of the flight control device.

[0090] As Figure 5 shown, the adjusting system of the flight control device provided by the embodiment of the present application comprises:

[0091] a flight control module 10 for implementing the adjusting method of the flight control device as described above, and a control device 20.

[0092] The control device 20 comprises a control lever, a rotating mechanism, an actuating module 30 connected in sequence, and a damper connected with the rotating mechanism, and the flight control module 10 is connected with the actuating module 30.

[0093] The flight control module 10 is configured to determine a corresponding actuating torque according to a current flight control mode, and control the actuating module 30 according to the actuating torque, so that the actuating module 30 adjusts the position of the control lever through the rotating mechanism.

[0094] It should be understood that the above is only an example, and does not constitute any limitation on the technical solutions of the present application. In specific applications, those skilled in the art can set it up according to the needs, and the present application does not limit it.

[0095] In the embodiment, the flight control module determines a corresponding actuating torque according to a current flight control mode, and controls the actuating module according to the actuating torque, so that the actuating module adjusts the position of the control lever through the rotating mechanism. In the above manner, the actuating torque is determined according to the flight control mode, and the actuating module is used to provide a control lever force for the control lever, so that the control lever can be flexibly adapted to different flight control modes. The type switching of the control lever can be controlled by the actuating module and the damper to be a centering rocker or a rocker without lever force, avoiding the instantaneous mutation of the flight control data caused by the mismatch between the type of the control lever and the mode requirement, and improving the stability and safety of the aircraft.

[0096] It should be noted that the above-described workflow is only illustrative and does not limit the scope of protection of the present application. In actual application, those skilled in the art can select part or all of them to achieve the purpose of the embodiment scheme according to actual needs, which is not limited here.

[0097] In addition, technical details not described in detail in the embodiment can be referred to the adjusting method of the flight control device provided by any embodiment of the present application, which will not be described here.

[0098] Referring to Figure 6 , Figure 6 is a structural schematic diagram of the first embodiment of the control device of the present application.

[0099] As Figure 6As shown, the operating device according to the embodiment of the present application is applied to the adjusting system of the flight operating device as described above, and the operating device comprises:

[0102] The actuating module 8 is drivingly connected with the mounting portion 7.

[0103] The damper 9 is drivingly connected with the mounting portion 7.

[0104] It should be understood that the pilot can hold the operating end 3 and pull the operating lever 1, at this time, the operating lever 1 rotates around the joint bearing 6, drives the rotating of the actuating module 8, generates the rotating displacement, the displacement sensor integrated in the actuating module 8 detects the operating displacement change, and sends the current operating lever displacement to the flight control module. At the same time, the operating lever 1 drives the damper 9 to generate axial stretching or compression, the damper 9 movement generates damping force, and the damping force provides the pilot with suitable damping force feeling, and the damping force linearly increases with the increase of the operating speed. After the flight control module receives the operating lever displacement, the corresponding actuating torque is determined according to the current flight control mode, the actuating module 8 is controlled to output the actuating torque, and the pilot is provided with suitable lever force characteristics.

[0105] It should be understood that the actuating module 8 is used for controlling the operating lever 1 to generate the active displacement, and the damper 9 is used for providing the resistance of the rotating movement of the operating lever 1. In one implementation manner, the flight control module controls the actuating module 8 to output the actuating torque, overcomes the movement resistance provided by the damper 9, drives the operating lever 1 to rotate through the rotating of the mounting portion 7, can realize the rotation to the neutral position of the operating lever displacement stroke, and makes the type of the operating lever 1 switch to the centering rocker; in another implementation manner, the actuating torque is 0, the actuating module 8 does not output the torque, the operating lever 1 keeps the position unchanged under the damping effect of the damper 9, and makes the type of the operating lever 1 switch to the lever force-free rocker.

[0106] Optionally, the actuating module 8 comprises a torque motor, and an output main shaft of the torque motor is drivingly connected with the mounting portion 7.

[0107] In the specific implementation, the actuating module 8 can be a torque motor, a hydraulic actuator or a pneumatic cylinder actuator and the like, which can make the operating lever 1 generate the active displacement, so as to control the type of the operating lever 1 to switch to the centering rocker or the lever force-free rocker through the actuating module 8 and the damper 9.

[0109] The damper 9 includes a first damping part and a first fixing part that are slidably installed, and the first fixing part is fixedly connected to the damper mounting support 10.

[0110] One end of the mounting rod 11 is hinged to the first damping part, and the other end is hinged to the mounting part 7.

[0111] It should be noted that, referring to Figure 6 In the control device of this embodiment, the damper 9 is fixed to the aircraft fuselage by the damper mounting bracket 10, and the mounting rod 11 forms a lever between the first damping part and the mounting part 7. When the control stick 1 rotates, the damper 9 is axially stretched or compressed, thereby providing motion resistance to the control stick 1.

[0112] Reference Figure 7 , Figure 7 This is a schematic diagram of the structure of a second embodiment of the operating device of the present invention. Figure 7 As shown, the damper 9 in this embodiment includes a second damping part and a second fixing part that are rotatably mounted relative to each other. The second damping part is driven to be connected to the mounting part 7, and the second fixing part is fixedly connected to the mechanism support 5.

[0113] It should be understood that, with reference Figure 7 In this embodiment, the damper 9 may be a circular damper. The second fixing part of the damper 9 is fixed to the mechanism support 5. The circular damper and the torque motor are mounted on the spherical bearing. The second damping part of the circular damper is coaxially connected to the output main shaft of the torque motor.

[0114] In another implementation, the second damping part of the circular damper is coaxially connected to the output main shaft of the torque motor and fixedly connected to the mechanism support 5. The control lever 1 is directly connected to the fixed part of the torque motor, and the fixed part of the torque motor is fixedly connected to the second fixed part of the circular damper.

[0115] In this embodiment, the actuation module of the control device causes the joystick to actively displace based on the actuation torque provided by the flight control mode. A damper is set to provide resistance to the rotational movement of the joystick. The actuation module and the damper control the joystick type to switch between a return joystick and a joystick without a lever force, so that the joystick can flexibly adapt to different flight control modes. This avoids instantaneous changes in flight control data caused by mismatch between the joystick type and mode requirements, and improves the stability and safety of the aircraft.
