Description

UAV communication system, device, method and computing device

Technical field

The present disclosure relates to the field of wireless control technologies, and in particular, to a communication system, device, method, and computing device for a drone.

Background technique

With the development of wireless control technology, drones have been widely used in production and daily life. In addition to the common communication systems consisting of dual-side devices and remote control devices, the application scenarios of multi-device interaction have received more and more attention in the field of drones. For example, after the head-mounted display is introduced on the ground side, the first-angle flight of the drone can be realized by cooperating with the remote controller and the drone. For example, many third-party equipment manufacturers have developed independent OSD (On-Screen Display) and flight control equipment for the drone side, thus providing rich expansion and selection for drone applications.

On the other hand, multi-device interactions also pose challenges to communication systems for drone applications. At present, two sets of hardware systems are usually used to realize image transmission (hereinafter also referred to as "picture transmission") and remote control signaling transmission functions of the drone. For the picture transmission part, the picture transmission module on the drone transmits the picture captured by the camera to the ground in real time, and the ground side device uses the receiving module to receive and display on the screen or the head mounted display. For the remote control signaling transmission part, the remote control information sent by the user operating the remote controller is received by the remote control receiving module on the drone and output to the flight control module through the corresponding interface, and then converted into the electric control command by the flight control module to control the motor speed, etc. parameter.

The functions of the above two systems are independent of each other, and they occupy a part of the frequency band resources at their respective frequencies. At the same time, the two systems mean that two antennas are needed, which not only takes up valuable space resources on the drone, but also the emission patterns of the two antennas are affected by each other. In addition, the two systems are usually designed independently by different product suppliers, and it is difficult to consider the structural interference problems that need to be avoided in the future.
