Problems solved by technology

[0002] At present, the aircraft landing gear monitoring at the airport is still observed by human eyes, and the telescope is used to identify long-distance aircraft to ensure the safety of the aircraft when the aircraft lands. However, in the case of strong sunlight and insufficient visibility, people are very It is difficult to effectively observe it
[0003] Now, some companies and research institutes are developing the topic of using infrared to monitor aircraft landing gear. Normal stowed or put down state causes misjudgment

Embodiment Construction

[0015] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0016] In this example, the pilots flying around the airport are well organized. Relative to the runway, the flight path during landing is a rectangular flight path, and it is at a specific altitude. This routing term is called a traffic pattern and enables pilots to find and anticipate the location of other pilots flying near the airport. This route should also be flown during practice takeoffs and landings.

[0017] When the aircraft is on the last unilateral side of the rectangular route, usually called the fifth side, when entering the fifth side, the landing gear starts to be placed, from the beginning of the landing gear of the civil aviation airliner to the full down, and the full down until the tires touch the ground, including three processes: First, the time when the landing gear of the aircraft is about 2000ft away from the r...

Abstract

The invention relates to an undercarriage safety monitoring method based on course line and visible data fusion. The method comprises the steps of providing an image monitoring module arranged at an airfield runway and a main control system arranged in a main control room and matched with the image monitoring module; searching, by the image monitoring module, a target aircraft on four sides of a rectangular traffic pattern, and when the target aircraft appears on four sides to five sides of the rectangular traffic pattern, i.e., appears a target aircraft undercarriage place, performing, by the image monitoring module, automatic target detection on the target aircraft, tracking and analyzing the target aircraft via the main control system, judging whether the target aircraft undercarriage is laid down, and then providing an early warning signal. The method greatly facilitates acquisition and analysis on the state of the aircraft undercarriage in the flight process, can judge the flight state of the aircraft, and provides technical and data support for planning of the course line and the laying-down strategy of the aircraft undercarriage.

Description

technical field [0001] The invention relates to a landing gear safety monitoring method based on fusion of aircraft route and visualization data. Background technique [0002] At present, the aircraft landing gear monitoring at the airport is still observed by human eyes, and the telescope is used to identify long-distance aircraft to ensure the safety of the aircraft when the aircraft lands. However, in the case of strong sunlight and insufficient visibility, people are very It is difficult to effectively observe it. [0003] Now, some companies and research institutes are developing the topic of using infrared to monitor aircraft landing gear. Whether it is normally put away or put down causes a misjudgment. Contents of the invention [0004] The purpose of the present invention is to provide a landing gear safety monitoring method based on fusion of aircraft route and visualization data, so as to overcome the defects in the prior art. [0005] In order to achieve the...
