一种基于图论的机场空域无人机流量控制方法

The logistics drone airport in the city needs the ability to take off and land multiple UAVs at the same time. An airport model with single inlet and single exit, route crossing and multiple aprons is designed for small and medium sized vertical takeoff and landing UAVs, and a flow control method based on graph theory to ensure flight safety is proposed. According to the flight status of drones in the field, arrival and departure time of drones are controlled, and flight routes within the airport are planned to ensure the flight safety of drones. The simulation results show that the flow control method can ensure safe and orderly flight of UAVs in the airport airspace. Arrival and departure operating capacity of airports with different sizes were tested separately. When the area of a single apron is fixed, the greater the number of aprons the larger the arrival capacity, but the smaller the arrival and departure capacity. Therefore, when designing an airport, it is necessary to properly plan the number of tarmac in a given airport area.
