Method and device for determining whether ship enters typhoon circle or not and electronic equipment

Abstract

The embodiment of the invention discloses a method and device for determining whether a ship enters a typhoon circle or not, electronic equipment and a computer readable medium. One specific embodiment of the method comprises the steps of acquiring a typhoon track information set in a preset time period wherien typhoon track information comprises typhoon wind ring radius information; and obtaining a ship position information set in a preset time period; processing data of each piece of typhoon trajectory information and each piece of ship position information to generate azimuth angle information, thereby obtaining an azimuth angle information set; determining wind ring radius information corresponding to the azimuth angle information according to the azimuth angle information and the typhoon wind ring radius information; processing data of each typhoon trajectory information and each ship position information to generate a relative distance and obtain a relative distance set; comparing each relative distance in the relative distance set with the air ring radius information to generate comparison information, thereby obtaining a comparison information set. According to the embodiment, the position of the ship entering a typhoon ring is predicted, and the timeliness of avoiding typhoon by the ship is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device, and electronic equipment for determining whether a ship enters a typhoon circle. Background technique [0002] At present, ships mainly rely on the typhoon joint early warning center to broadcast the typhoon circle forecast information. However, there will be a certain time error in the broadcast of the Typhoon Joint Warning Center. At the same time, it does not take into account that the radius of the typhoon's forward direction during its movement is larger than the radius of influence behind it. Looking forward to solving the above problems, we can use the distance and azimuth angle between the center point of the typhoon and the position of the ship, and compare the radii of the wind circles in different quadrants to determine whether the ship has entered the typhoon wind circle. Contents of the invention [0003] The Summary ...
