A flight limit weight measurement method, device and system based on obstacle analysis

Abstract

The present invention provides a method, device and system for measuring flight limit weight based on obstacle analysis. The method includes: acquiring flight environment information and a starting coordinate point of flight, and taking the starting coordinate point as a starting point, according to the The flight environment information is calculated to obtain M flight trajectory points; the adjacent two flight trajectory points are connected into N flight segments; the N flight segments are connected into a flight trajectory; a flight protection zone is determined based on the flight trajectory; Find the obstacle distance between the obstacle in the flight protection zone and the flight trajectory; determine the flight limit based on the obstacle distance and the flight environment information. The invention can improve the calculation accuracy of the track and the protected area, improve the calculation efficiency, reduce the human operation, reduce the human error, improve the flight safety and reduce the accident risk.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a method, device and system for measuring flight limit weight based on obstacle analysis. Background technique [0002] With the rapid development of the economy, the aviation industry has gradually developed vigorously, and at the same time brought more convenience to the appearance of the people. [0003] Due to the heavy weight, slow flight speed and poor flight performance of the aircraft, the take-off stage is a high-incidence operation stage for aviation accidents. In order to improve the safety of flight, the obstacles in the airport area are analyzed and detected before the flight, and the safety assessment is generally carried out along the flight trajectory of the aircraft. If the assessment fails to meet the requirements, a new route is redesigned for the aircraft with poor performance. At present, the commonly used method is manual detection, then draw the flight trajectory a...

Problems solved by technology

[0004] However, the existing technology mainly has the following deficiencies: first, the human error is large, the recognition is not accurate, and the artificially drawn flight trajectory and the protected area are easy to ignore factors such as map projection, resulting in large errors in the measured parameters; second, the efficiency Low: Manual obstacle analysis often takes a lot of time to draw the flight program trajectory and its protection zone and dot the obstacle position on the map, which not only increases the time, but also increases the labor cost
