General aviation air collision detection method, device and general aircraft

Abstract

The invention provides a general aviation air collision detection method. The method includes the following steps that: the current heading angle, turning speed, aviation speed and position of a local aircraft are obtained, and the current heading angle, turning speed, aviation speed and position of the other aircraft are also obtained; the prediction flight path of the local aircraft in a further period is estimated according to the current heading angle, turning speed, aviation speed and position of the local aircraft; the prediction flight path of the other aircraft in a further period is estimated according to the current heading angle, turning speed, aviation speed and position of the other aircraft; and whether a collision exists between the local aircraft and the other aircraft is judged according to the prediction flight path of the local aircraft and the prediction flight path of the other aircraft. According to the aviation air collision detection method of the invention, flight path prediction is carried out based on the parameters such as the heading angle and turning speed, and therefore, the accuracy of flight path prediction of a general aircraft can be improved, and the accuracy of collision detection can be improved, and thus, a high-accuracy air collision detection method can be provided for general aviation.

Description

technical field [0001] The invention relates to the technical field of general aviation, in particular to a conflict detection method and device in general aviation and a general aircraft. Background technique [0002] General aviation, referred to as general aviation, refers to the use of civil aircraft to engage in civil aviation activities other than public air transport, including operational flights in industry, agriculture, forestry, fishery and construction, as well as medical and health care, emergency rescue and relief, meteorological detection, marine Flying activities in monitoring, scientific experiments, education and training, cultural and sports, etc. The flight area of ​​general aviation is low-altitude airspace. my country's low-altitude airspace usually refers to the space range below the true height of 10m. Because general aviation activities have low flying altitude, strong maneuverability and effectiveness, and are greatly affected by factors such as wea...

AI Technical Summary

Problems solved by technology

[0005] However, due to the large difference between the flight characteristics of general aviation and civil aviation, the uniform rate trajectory prediction model adopted by TCAS will greatly reduce the accuracy of trajectory prediction in the highly maneuverable general aviation flight environment, which directly affects the conflict detection in general aviation. As a result, the flight conflict detection technology suitable for civil aviation in the prior art is not suitable for general aviation, so it is imminent to study a set of air conflict detection methods suitable for general aviation
