Embodiment Construction

[0026] In actual flight management, the aircraft may not be able to take off on time according to its original flight plan due to the influence of various factors before take-off, resulting in a delay in the take-off time of the aircraft. The time when the actual take-off time is delayed from the planned take-off time in the flight plan is the ground delay, which is referred to as delay time in the following embodiments. Among them, the sources of the flight plan are airlines and various civil airports; the flight plan includes the planned take-off time of all aircraft to be processed, and its flight path, that is, the flight path; the flight path includes the starting point, the ending point and the waypoint of the flight.

[0027] When the distance between the two aircraft is less than the specified flight safety interval, it is considered that there is a conflict between the two aircraft, and the method of detecting whether there is a conflict between the aircraft is the con...

Abstract

The invention discloses a method and a device used for removing flight conflicts and based on a packet mode. When conflicts of an aircraft and other aircrafts are judged to exist, all aircrafts are divided into x subgroups according to delay time and flight plans of the aircrafts in a gene sequence with the highest fitness. Self fitness of two gene sequences selected from a population is compared, and the delay time in the subgroups is inherited by a preferable gene sequence to obtain two inherited sub-gene-sequences. If the number of the obtained sub-gene-sequences is judged to be m, when the number of the subgroups finishing executing of the steps is judged to be x, an optimized population is obtained, a gene sequence with the highest fitness is obtained, and an optimized flight plan is generated, and therefore the method and the system are favorable for conducting overall optimization on the flight plans and removing large-scale flight conflicts.

Description

technical field [0001] The present invention relates to aviation technology, in particular to a method and device for resolving flight conflicts based on grouping. Background technique [0002] With the rapid development of my country's aviation industry, the volume of aviation business is increasing day by day, and the flight traffic has greatly increased. Correspondingly, the density of aircraft in the airspace increases, making it difficult to guarantee the safe separation between aircraft, thus increasing the possibility of flight conflicts. The number of civil aviation flights across the country averages over 7,000 per day, and the scale and number are very large. At the same time, the national civil aviation flight plan is coordinated and formulated by multiple units and departments such as airlines, airports, and air traffic control bureaus, and the distribution of national routes is complex, so flights will inevitably conflict with other flights during the flight. ...
