Problems solved by technology

Both the intelligent monitoring and traffic management of ships need to be based on the actual ship coordinates. The coordinates broadcast by pure AIS broadcast cannot meet the increasingly stringent requirements and are not conducive to maritime management.

Embodiment Construction

[0042] like figure 1 As shown, the present embodiment provides a method for correcting ship coordinates based on AIS, comprising the following steps:

[0043] S1. After obtaining the AIS information, obtain the ship's coordinate information, speed over ground information, heading information, slew rate information and time information from the AIS information;

[0044] The AIS information is sent by the AIS equipment on the ship, and the AIS information specifically includes information such as the ship's identification code, ship name, position, course, ship speed, time, tonnage, etc. Therefore, the coordinate information of the ship can be obtained from the AIS information , Ground speed information, heading information, slew rate information and time information. The coordinate information is the position cheating information at the moment when the AIS equipment on the ship sends the AIS information, and the coordinate information can be satellite positioning coordinate in...

Abstract

The invention discloses a ship coordinate correction method, system and device based on AIS and a storage medium, and the method comprises the following steps: obtaining the coordinate information, to-ground navigation speed information, course information, rotation speed information and time information of a ship from the AIS information after the AIS information is obtained; and correcting the coordinates of the ship in combination with the coordinate information, the over-the-ground navigation speed information, the heading information, the rotation speed information and the time information. According to the invention, the related information is obtained from the AIS information for calculation, thereby automatically achieving the correction of the position coordinates of the ship, obtaining more precise coordinates, meeting the requirements of the intelligent monitoring and traffic management of the ship, facilitating the maritime affair management, and being capable of being widely used in the field of ship management.

Description

technical field [0001] The invention relates to the field of ship management, in particular to an AIS-based ship correction method, system, device and storage medium. Background technique [0002] The AIS system refers to the ship's automatic identification system, that is, the Auto Identification System. The AIS system will broadcast the ship's own identity information in the form of VHF (Very High Frequency) radio, including the unique identification code, ship name, position, and course. , ship speed, rate of rotation (abbreviated ROT) and other information. AIS is designed by maritime regulators to manage water traffic. The International Maritime Organization has defined the specific functional requirements of the AIS system and the configuration requirements of different types of ships for AIS. [0003] However, the broadcast of the AIS system is not continuous. According to the corresponding specification requirements, the broadcast frequency of Class A AIS is "every...
