The invention discloses a method for multi-machine cooperation and video relay transmission, and relates to the technical field of wireless communication. The method includes the steps of: deploying cooperative control communication waveforms; performing search tasks; relaying communication link requests; establishing relay communication links: the cluster head aircraft sends a deployment command containing relay communication waveforms and relay communication waveforms to related UAVs. The ROS message of position information, after receiving the ROS message, the UAV deploys the corresponding relay communication waveform and flies to the relay position to hover, and then sends a confirmation message to the cluster head aircraft. When the cluster head aircraft receives all the confirmation messages, the center The following link is established; the target video information is relayed: after the UAV that has searched for the target receives the ROS message sent by the cluster head aircraft that contains the success information of the relay link establishment, it transmits the video information through the relay communication link to the command center. The method has the advantages of good versatility, easy upgrading, and facilitates cooperative control of unmanned aerial vehicle clusters and real-time relay transmission of video information.
Description
technical field [0001] The present invention relates to the technical field of communication methods, in particular to a multi-device collaboration and video relay transmission method. Background technique [0002] In recent years, UAV technology has developed rapidly and is widely used in various fields such as reconnaissance and relay communication. However, the ability of a single UAV is limited, and it is difficult to meet the needs of complex tasks. Therefore, the concept of UAV cluster technology came into being. The main idea is: a large number of UAVs with limited capabilities cooperate to complete high-complexity tasks. . A key technology of UAV cluster is multi-machine coordination. At present, many researchers introduce the Robotic Operation System (ROS) into the UAV cluster, and use the ROS system to realize the coordination between UAVs. [0003] The ROS system is the de facto standard in the field of robotics and has been widely used in many robotic systems....
