The embodiment of the present application provides a signal transmission method based on a TYPE-C interface (hereinafter, referred to as a signal transmission method for short), which may be applied to a product that can be connected based on the TYPE-C interface.

For example, as can be seen from fig. 1 (fig. 1 is an application scenario schematic diagram of the embodiment of the present application), the signal transmission method of the embodiment of the present application may be applied to the unmanned aerial vehicle 100 and the storage device 200 based on TYPE-C interface connection.

Among them, the drone 100 may include an unmanned aerial vehicle, an agricultural drone, and the like.

In some embodiments, as shown in fig. 2, the drone 100 may include an unmanned aerial vehicle 110, a display device 130, and a control terminal 140. Unmanned aerial vehicle 110 may include, among other things, a power system 150, a flight control system 160, a frame, and a pan and tilt head 120 carried on the frame. The unmanned aerial vehicle 110 may be in wireless communication with the control terminal 140 and the display device 130.

The motor 152 is used to drive the propeller to rotate, thereby providing power for the flight of the UAV 110, which enables the UAV 110 to achieve one or more degrees of freedom of motion. In certain embodiments, the UAV 110 may rotate about one or more axes of rotation. For example, the above-mentioned rotation axes may include a Roll axis (Roll), a Yaw axis (Yaw) and a pitch axis (pitch). It should be understood that the motor 152 may be a dc motor or an ac motor. The motor 152 may be a brushless motor or a brush motor.

The flight control system 160 may execute the image processing method of the embodiment of the present application, adjust the visible light image, and control the flight of the unmanned aerial vehicle 110 according to the adjusted visible light image. Or the camera 123 adjusts the visible light image and performs image recognition based on the adjusted visible light image, or the camera 123 may send the adjusted visible light image and the infrared image to the terminal device or the control device through the wireless link for display.

The display device 130 is located at the ground end of the unmanned flight system 100, can communicate with the unmanned aerial vehicle 110 in a wireless manner, and can be used to display attitude information of the unmanned aerial vehicle 110. In addition, an image photographed by the photographing device 123 may also be displayed on the display apparatus 130.

Wherein the TYPE-C interface comprises a female socket and a male socket, the TYPE-C interface will now be described in detail with reference to fig. 3.

As shown in fig. 3, the female socket and the male socket both include 24 pins, and both include a surface a and a surface B, and the definition sequence of each pin is still the same after the surface a and the surface B are turned over, so the TYPE-C interface can be configured without dividing the front side and the back side.

The TYPE-C interface is introduced as follows, taking the female socket as an example:

as shown in fig. 3, 12 pins (a 1-a 12 shown in fig. 3) of the a surface of the female socket are GND, TX1+, TX1-, VBUS, CC1, D +, D-, SBU1, VBUS, RX2-, RX2+, and GND, respectively; the 12 pins (B12-B1 shown in FIG. 3) on the B surface of the female socket are GND, RX1+, RX1-, VBUS, SBU2, D-, D +, CC2, VBUS, TX2-, TX2+ and GND respectively.
