Terminal area airline safety tolerance monitoring method based on collision risk model and system thereof

Abstract

The invention discloses a terminal area airline safety tolerance monitoring method based on a collision risk model and a system thereof, and relates to the technical field of terminal area surveillance. A lateral and vertical track deviation distribution model is established according to an automatic dependent surveillance broadcast observation data; the risk of flight collision is calculated on the basis of the collision risk model according to track deviation; and distance to an assumed parallel route, i.e. the maximum permissible airplane track deviation range, is solved through iteration by utilizing monotonicity of the risk of flight collision and a lateral and vertical safety interval under the condition of the given risk of flight collision according to the flight state of an airplane on the airline. The system comprises a data preprocessing model, a track deviation modeling module and a track safety tolerance assessment module. Terminal area airline safety tolerance monitoring is realized so that the risk of collision under a complex terminal area environment can be effectively reduced and air traffic control operation safety level and airspace capacity can be enhanced.

Description

technical field [0001] The invention relates to the technical field of terminal area monitoring, in particular to a method and system for monitoring the safety tolerance of terminal area routes based on a collision risk model. Background technique [0002] The terminal area is a medium and low-altitude airspace covering a large range, even several central cities, and the geographical environment in this space is complex. With the increase of flight traffic in the terminal area, the flight density becomes larger. In order to deal with these problems, it is necessary to reduce the control interval and improve the navigation accuracy of flight routes. Therefore, in order to ensure flight safety, it is necessary to monitor the safety tolerance of the terminal area route in real time. The safety tolerance of the route in the terminal area refers to the maximum deviation range between the actual flight track and the center line of the route that is allowed when the collision risk...
