Automatic ship recognizing method based on Beidou positioning navigation

Abstract

The invention discloses an automatic ship recognizing method based on Beidou positioning navigation. The method includes the following steps of S100, classifying ships, and marking the bottom ends ofthe ships with codes according to the different classifications; S200, generating a ship bottom end high-resolution orthoimage based on high-resolution satellite remote sensing technology, arranging apressure sensor and a Beidou positioning and monitoring station at the bottom of each ship, making the pressure sensors in communication connection with the Beidou positioning and monitoring stations, and collecting the ship information through the Beidou positioning and monitoring stations; S300, establishing a ship information concentrating station for each water area, and making the ship information concentrating stations in communication connection with the Beidou positioning and monitoring stations through a Beidou satellite and receive the ship information sent by the Beidou satellite;S400, arranging positioning controllers in the ship information concentrating stations, and processing the ship information received by the ship information concentrating stations through the positioning controllers. The function of accurately and efficiently positioning the ships is achieved when the ships are automatically recognized.

Description

technical field [0001] The invention relates to the technical field of automatic identification of ships, in particular to a method for automatic identification of ships based on Beidou positioning and navigation. Background technique [0002] Automatic Identification System (AIS for short) is a new type of navigation aid system and equipment. The correct use of AIS helps to strengthen the safety of life at sea, improve the safety and efficiency of navigation, and protect the marine environment. The functions of AIS are: [0003] (1) Identify the vessel; [0004] (2) Assist in tracking the target; [0005] (3) Simplify information exchange; [0006] (4) Provide other auxiliary information to avoid collisions. [0007] AIS improves the insurance factor of collision avoidance between ships, enhances the functions of ARPA radar, ship traffic management system, and ship report, displays the visual heading, route, ship name and other information of all ships on the electronic...

AI Technical Summary

Problems solved by technology

[0008] Although the combination of AIS into VTS (Vessel Traffic Service) at home and abroad has become the main way for ships to identify and communicate with each other, due to the limitation of communication distance, especially in the process of ocean voyage, AIS cannot complete the information receiving and sending, so that the mutual identification and communication between ships cannot be realized
