11. The method of any one of claims 8-10, wherein the remote server and the ground control device communicate via P2P, comprising:
the ground control equipment sends monitoring data to the remote server through P2P, and the monitoring data are used for indicating the flight state of at least one unmanned aerial vehicle.
12. A data transmission method, characterized in that the data transmission method comprises:
the ground control device sends request information to a remote server through an end-to-end P2P technology, wherein the request information is used for requesting communication between the ground control device and the remote server through P2P;
after the ground control device receives feedback information of the remote server, the ground control device communicates with the remote server through P2P, and the feedback information is used for indicating that the ground control device successfully communicates with the remote server through P2P;
or when the ground control equipment does not receive the feedback information of the remote server, the ground control equipment forwards the feedback information through the cloud server and communicates with the remote server.
