Method for evaluating flight safety of unmanned aerial vehicle in a typhoon yard

Abstract

The invention discloses a method for evaluating the flight safety of an unmanned aerial vehicle in a typhoon yard, and the method comprises the steps that: a typhoon center is positioned, and the flight safety is evaluated, the positioning of the typhoon center is mainly used for calculating the rotation of the whole typhoon yard according to the east-west wind speed, the south-north wind speed and the vertical wind speed in the typhoon yard, and the typhoon center is positioned according to the rotation degree and the absolute value of the resultant wind speed; and the evaluation of the safety of the unmanned aerial vehicle flying in the typhoon field mainly comprises the steps that different research radiuses are determined firstly, the radiuses refer to the distance between the research position and the center of the typhoon, and then the probability that the unmanned aerial vehicle encounters the dangerous wind speed on the wind ring determined by the radiuses is calculated according to the wind resistance of the unmanned aerial vehicle. According to the invention, the flight safety of the unmanned aerial vehicle in the typhoon yard can be evaluated, and then the planning of the flight route of the unmanned aerial vehicle in the typhoon yard can be guided.

Description

technical field [0001] The invention relates to the technical field of drone flight safety, in particular to a method for evaluating the flight safety of drones in typhoon fields. Background technique [0002] Typhoon is one of the most serious natural disasters in nature, which is characterized by strong suddenness and great destructive power. my country's southeastern coastal areas are often hit by typhoons, and typhoons often bring disastrous weather such as strong winds and heavy rains, which have a great impact on flight safety. The center of the typhoon is called the eye of the typhoon, which is the concentric circle from the inside to the outside, respectively, the vortex wind and rain area and the peripheral gale area. The formation of the typhoon eye is due to the fact that the wind in the typhoon blows in a counterclockwise direction, causing the air in the center to rotate, and the centrifugal force caused by the rotation balances and cancels out the force of the...
