Abstract

An embodiment of the invention provides an aircraft conflict relief method and device. The problem of the conflict relief of a large number of aircrafts in the airspace can be solved, the calculation accuracy is high, the speed and angle adjustment can be performed on the aircrafts, and the actual requirements are met. According to the specific scheme, the aircraft conflict relief method comprises establishing a conflict relief model based on integer programming, wherein the conflict relief model comprises an objective function and a constraint condition group and parameters of the objective function comprise flight speed adjustment parameters and course angle adjustment parameters of the aircrafts in a sector; obtaining flight data of the aircrafts in the sector, wherein the flight data comprise the position, the flight speed and the course angle of every aircraft; serving the flight data as the input of the conflict relief model to obtain integer solutions of the flight speed adjustment parameters and the course angle adjustment parameters; performing the conflict relief on the aircrafts in the sector according to the integer solutions of the flight speed adjustment parameters and the course angle adjustment parameters. The aircraft conflict relief method and device are applied to the aircraft conflict relief.

Description

technical field [0001] Embodiments of the present invention relate to flight technology, and in particular to a method and device for conflict resolution of an aircraft. Background technique [0002] In the traditional air traffic control system, the planning, monitoring, and command of air traffic are all undertaken by the management departments on the ground. The contradiction between management efficiency and management needs is becoming more and more prominent. Therefore, it is necessary to break the traditional inefficient navigation management rules, that is, to adopt the free flight mode, so that the aircraft can freely choose the flight path. The key to achieving free flight is to ensure that there is always a safe distance between aircraft to avoid the risk of collision. Since free flight allows free choice of routes, the possibility of conflict between aircraft will be greatly increased. How to provide pilots with real-time auxiliary decision-making to solve confl...

AI Technical Summary

Problems solved by technology

[0003] Aircraft conflict detection and resolution is an important means to ensure the flight safety of aircraft. At present, the research in this field at home and abroad mainly includes two types: centralized and distributed. The distributed algorithm does not consider fuel consumption and path when conflict is resolved, and the calculation accuracy is relatively low. , compared with the distributed algorithm, the calculation accuracy of the centralized algorithm is relatively high, so the centralized algorithm is often used when the aircraft conflict is resolved

Centralized algorithms mainly include evolutionary algorithms, linear programming, and quantitative control, etc. However, the existing centralized algorithms cannot meet the requirements of conflict resolution when there are a large number of aircraft in the airspace, and the calculation accuracy is still not accurate enough. single parameter
