Embodiment Construction

[0021] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] 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 when the collision risk of the arrival and departure operations meets the requirements of the flight collision risk. The monitoring of the dynamic safety margin of arrival and departure is an important means of guaranteeing the safety of flight airspace in dense terminal areas. According to the size of the flight safety boundary, air traffic controllers can dynamically adjust the flight density in the terminal area to improve the utilization rate of the terminal area.

[0023] The present invention uses the collision risk model to solve the problem of safety margin monitoring in the terminal area under complex conditions, and proposes a method for monitorin...

Abstract

The invention discloses a method and system for monitoring the safety tolerance of a terminal area route based on a collision risk model, and relates to the technical field of terminal area monitoring. The invention establishes lateral and vertical track deviation distribution models according to broadcast automatic correlation monitoring observation data; calculates the flight collision risk based on the collision risk model according to the track deviation; Using the monotonicity of the flight collision risk and the lateral and vertical safety intervals, iteratively calculate the distance from the hypothetical parallel flight path, that is, the maximum allowable aircraft track deviation range. The system includes a data preprocessing module, a track deviation modeling module and a track safety margin evaluation module. The invention realizes the monitoring of the safety tolerance of the route in the terminal area, can effectively reduce the collision risk in the complex environment of the terminal area, and improves the safety level and airspace capacity of air traffic control operation.

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...
