Abstract

In order to reduce risk of collision between non-cooperative large UAVs, firstly, in light of analysis on their operation mode, predication mechanism and procedure of flight conflict based on UAVs operation and management platform were proposed. Secondly, a conflict prediction model building on UAVs flight state data was proposed, which predicted conflicts in both horizontal and vertical directions and determined whether there would be a conflict. And then warning threshold was analyzed to prevent too late reception of alarm information by UAVs ground station. Finally, real-time flight status data of 3 UAVs were used to analyze and verify the model. The results show that the proposed mechanism and program can realize prediction and early warning between non-cooperative large UAVs, and the prediction model can accurately determine whether there is a flight conflict as well as calculate when it will happen. © 2019 China Safety Science Journal
