Title:
MULTI-DIMENSIONAL AIRCRAFT COLLISION CONFLICT RISK EVALUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/196504
Kind Code:
A1
Abstract:
A multi-dimensional aircraft collision conflict risk evaluation system in the field of civil aviation aircraft collision conflict prediction. The system executes the steps of: S1, calculating probabilities that an aircraft overlaps other aircrafts in three dimensions; S2, calculating loss interval rates of the aircraft in the three dimensions; S3, obtaining probabilities that the aircraft conflicts and collides with the other aircrafts in three dimensional directions; S4, comparing the probabilities that the aircraft conflicts and collides in the three dimensional directions to obtain a maximum probability and a dimension corresponding to the maximum probability; and S5, performing difference value calculation on the obtained maximum probability and a safety standard, and giving safety evaluation according to a difference value. Therefore, multi-dimensional calculation of the collision conflict risk probability of the aircraft is implemented. The maximum value of the collision conflict risk probability is obtained, and a judgment basis for comprehensive safety evaluation of the aircraft is provided on the basis of the maximum value.
