AI Technical Summary

Technical Problem

Existing drones in urban emergency rescue face problems such as link disconnection caused by frequent changes in network topology, increased signaling overhead and waste of spectrum resources due to mixed transmission of control data and data, and low network stability and rescue efficiency under highly dynamic topology.

Method used

A dual-frequency link architecture is adopted, separating the low-frequency control link and the high-frequency data link. The low-frequency control link adopts a fully distributed networking method, while the high-frequency data link constructs a stable data transmission link through global information, transmitting control information and data information respectively.

Benefits of technology

Stable control and efficient data transmission of UAV networks under highly dynamic topology have been achieved, improving network connectivity and rescue efficiency, and reducing the risk of UAV damage.
