ADAPTIVE COMMUNICATION LINK SWITCHING METHOD, MOVABLE PLATFORM, AND CONTROL APPARATUS

WIPO Patent Application WO/2020/133393

A1

Disclosed are an adaptive communication link switching method, a movable platform, a control apparatus, and a computer-readable medium. The method is applied to the movable platform, and comprises: periodically generating and sending a test data packet, so as to determine whether a second communication link is available; determining, based on a signal quality parameter of a first communication link, whether the communication quality of the first communication link meets requirements; and when the communication quality of the first communication link does not meet requirements and the second communication link is available, performing communication link switching from the first communication link to the second communication link. According to the adaptive communication link switching method of the present invention, a standby communication link is added, such that adaptive communication link switching can be performed between a dedicated communication link and the standby communication link, and the advantages of low delay and no extra cost of the dedicated communication link are fully utilized and the phenomenon of a movable platform being out of control and losing image transmission data can also be effectively avoided.
