A Study on the Algorithm for Real Time Flight Conflict Detection and Resolution During Low-altitude Rescue
摘要
Abstract
Real-time flight conflict detection and resolution algorithm is very important to aviation emergency rescue under the environment of complex low-altitude airspace.Based on low-altitude visual flight rules,this paper constructed a three-dimensional spatial grid,using the time window theory to analyze the temporal and spatial conflict of two flights. Based on visual flight rules during rescue and performance constraints of aircrafts,a feasible path set and Airspace model based on mesh generation for flight Agents are developed.Then priority of each Agent is identified at the conflicting point. Feasible non-conflict paths can be obtained by using the Agent model.Then an optimal path planning method is developed and the paths without any conflicts are created.The results are verified through a simulation,and the time window and the area of flight conflict,and the paths without any conflicts under different priority are analyzed.The results show that this method can provide a higher solution efficiency than non-collaborative methods,which can save a flight time of 146 s.关键词
