Specifically, the method of the embodiment of the present invention includes the following steps.

S201: Acquire rotation state information of a target motor in one or more motors, where the rotation of the target motor is caused by an external force applied to it by a user.

In the embodiment of the present invention, the control device may obtain the rotation state information of the target motor in one or more motors, wherein the rotation of the target motor is caused by the external force applied to it by the user.

In an embodiment, the control device may trigger the rotation of the target motor by the user applying an external force to one or more motors of the drone to obtain the rotation state information of the target motor. In some embodiments, the control device may obtain the rotation state information of the target motor through a drone motor state monitor, and the specific implementation is as described above.

Take Fig. 3 as an example again. Fig. 3 is a schematic diagram of the application control method provided by the embodiment of the present invention. As shown in Fig. 3, the unmanned vehicle 301 is taken as an example. A motor (not shown) that provides moving power for the car. The motor rotates and connects to the wheel 302. The user's hand 303 can apply an external force to the wheel 302. The wheel 302 rotates in the direction shown in FIG. Rotate the connected motor to rotate.

S202: Generate a control signal according to the rotation state information of the target motor.

In the embodiment of the present invention, the control device may generate a control signal according to the rotation state information of the target motor. In some embodiments, the control signal includes a digital control signal and/or a digital control signal, and the digital control information and the digital control signal are explained as described above.

In one embodiment, when the control device generates a control signal according to the rotation state information of the target motor, it may determine whether the rotation state of the target motor is consistent with at least one preset state according to the rotation state information of the target motor. A preset target rotation state among the target rotation states is matched, and when a match is determined, a control signal associated with the matched preset target rotation state is generated. In some embodiments, each preset target rotation state in the at least one preset target rotation state corresponds to an action task. In some embodiments, the action task may include, but is not limited to, the movement task of the drone, the action task of each load on the drone, etc. The load of the drone includes, but is not limited to, a camera, a spray device, PTZ, audio playback device, etc.

For example, suppose that the drone includes four motors, namely motor 1, motor 2, motor 3, and motor 4. Among them, the rotation states of motor 1 and motor 2 correspond to the preset action tasks. Assume that in the preset target rotation state, The rotation angle of the motor 1 corresponds to the matching action task of the pan/tilt rotation angle, and the rotation state of the motor 2 corresponds to the matching action task of spraying pesticides. If the rotation angle of the motor 1 is 50 degrees, and the corresponding matching action task is that the pan/tilt of the unmanned aerial vehicle rotates 50 degrees, a control signal can be generated and controlled to rotate the pan/tilt by 50 degrees. If the motor 2 is in a rotating state, and the corresponding matching action task is to start the spraying device of the drone, a control signal to control the pesticide spraying device of the drone can be generated.

The control terminal can display a control interface, and can perform an editing operation on the control interface to determine the action task corresponding to each of the at least one preset target rotation state and the at least one preset target rotation state.

In addition, the user can click the icon of motor No. 1 in the motor edit box 403, the control interface can pop up a dialog box for editing the preset target rotation state, and the user can operate the dialog box to determine the preset target state, for example, rotate 360 degree. The target motor is determined to be the No. 1 motor, and the preset target rotation state is determined to rotate 360 degrees. Further, the user can drag the photo icon from the action task list 401 to the edit box 404, so that the action task corresponding to the preset target rotation state is determined to be a photo. After the editing is completed, the control device will obtain the rotation state information of the No. 1 motor. When the control device determines that the rotation state of the No. 1 motor matches the 360-degree rotation state according to the rotation state information of the No. 1 motor, A control signal associated with the 360-degree rotation state is generated, and the drone is then controlled to perform an action task corresponding to the 360-degree rotation state, that is, a photographing task, according to the control signal.

If the rotation speed of the target motor is 1000 revolutions per minute, the corresponding matching action task The spraying device of the man-machine sprays pesticides at a rate of 2 liters/minute, and then a digital quantity control signal for controlling the spraying device of the drone to spray pesticides at a rate of 2 liters/minute can be generated.

In one embodiment, the control signal includes a switch value control signal, and when the control device generates a control signal associated with the matched preset target rotation state, it can generate a switch value associated with the matched preset target rotation state. control signal.

For example, suppose that the drone includes a motor 1 and a motor 2. If the preset target rotation state is that the motor 1 rotates counterclockwise and the motor 2 rotates clockwise, the action task corresponding to the preset target rotation state In order to turn on the audio playback device of the drone, when the control device determines that the rotation state of the motor 1 and the motor 2 matches the preset target rotation state according to the rotation state information of the motor 1 and the motor 2, the control device can generate and turn on the drone The on-off control signal of the audio playback device is used to control the drone to turn on the audio playback device.
