Problems solved by technology

[0005] 1. The flight area of ​​the airport does not belong to the open space (aviation control). In a relatively closed environment, if the traffic, navigation, and geographic information in the airport flight area are not updated in time, it is easy to cause safety hazards
[0006] 2. Traffic, navigation, geographic information, etc. are not updated in time, which is not conducive to traffic safety management in the airport flight area, and traffic conflicts (traffic conflicts between vehicles, traffic conflicts between vehicles and aircraft, etc.) are prone to occur, resulting in safety accidents
[0007] 3. The existing technical solutions, once a traffic conflict occurs in the airport flight area (even if no accident occurs), it will also affect the operation of vehicles and aircraft in the traffic conflict area (or adjacent areas)
Vehicles and aircraft without traffic conflicts need to be dispatched manually (or even stand by), which seriously affects the efficiency of airport operations

Abstract

The invention discloses a path planning method for an airport flight area, which includes real-time collection of aircraft operating status in the airport flight area, vehicle driving status in missions and vehicle task assignment status, road network dynamic data, vehicle traffic status and aircraft traffic status; According to the data collected in step S1, the real-time dynamic planning vehicle is in the aircraft road network path and the road road network path; collect high-precision map data, and display the real-time dynamic paths of aircraft and vehicles in the flight area on the high-precision map data; All traffic conflict points in the road network on the precision map; conflict warnings are issued to vehicles and aircraft passing through traffic conflict points. The invention discloses a path planning system used in the flight area of ​​an airport. The invention can avoid potential safety hazards caused by information data lag caused by task dominance, is beneficial to traffic safety management in the flight area of ​​the airport, and can avoid traffic conflicts and safety accidents from affecting the operating efficiency of the entire airport.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a path planning method for airport flight areas. The invention also relates to a path planning system for an airport flight area. Background technique [0002] For the airport flight area road network, it is a huge, complex and dynamic traffic application scenario. Traditional airport flight area road network data collection often requires a large amount of manpower to conduct OD surveys and data collection in the early stage, and combine aircraft and vehicle tasks (starting point, destination, and time information) to form airport flight area road network data. According to the road network data, follow-up aircraft and vehicle tasks are managed to realize traffic management in the airport area. [0003] The path followed by an aircraft on the ground is usually assigned to the aircraft by air traffic controllers or ground controllers, for example by means of radio communication equipmen...
