Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] combine figure 1 , figure 2 , image 3 , the present invention proposes a method for diverting an aircraft based on weather radar data under dangerous weather conditions, specifically comprising the following steps:

[0020] Step 1, set up the thunderstorm area

[0021] According to the radar echo pictures provided by the weather radar, image processing technology is used to separate different levels of thunderstorm areas, and at the same time combined with the echo top height and echo bottom height pictures provided by the weather radar, the height variation range of each thunderstorm area is obtained, and Display different levels of thunderstorm areas on the empty map; specifically:

[0022] Step 101, processing the radar echo image, obtaining the RGB color value of each echo level, and obtaining the position of each thunderstorm pixel point according to ...

Abstract

The invention discloses a method for diverting an aircraft under dangerous weather conditions on the basis of weather radar data. Firstly, related weather data are acquired through weather radar, thunderstorm areas at different dangerous grades are drawn, and the position and the range of influence of the thunderstorm area at each dangerous grade are determined; secondarily, an aircraft diversion route planning model is established according to the dangerous grades of the thunderstorm areas; finally, a safe flight route avoiding the dangerous thunderstorm areas is planned in real time for the aircraft in combination with a dynamic diversion route planning method, and the aircraft is diverted in the dangerous weather. By means of the method, the safe flight route can be automatically planned for the aircraft under the dangerous weather condition, the workload of an air traffic control worker is effectively reduced, and safe flight of the aircraft in the dangerous weather is guaranteed.

Description

technical field [0001] The invention relates to the special technical field in the field of aviation control, in particular to an aircraft diversion method under dangerous weather conditions based on weather radar data. Background technique [0002] With the rapid development of my country's civil aviation transportation industry, a large number of flight delays follow, among which dangerous weather has become an important factor affecting flight delays in our country, so how to reduce flight delays in dangerous weather, improve the utilization of airspace resources, Ensuring the safe flight of aircraft has become an urgent problem for us to solve. [0003] In the civil aviation system, dangerous weather refers to weather phenomena that affect aircraft flight safety, mainly: thunderstorms, turbulence, wind shear, visual range obstruction and strong winds, etc. According to the statistics of historical civil aviation meteorological flight accidents, there are 47% of flight ac...
