Multi-network fusion-based vessel supervisory system and data exchange method thereof

Abstract

The invention discloses a multi-network fusion-based vessel supervisory system and a data exchange method thereof. The system comprises a ship-borne subsystem, a shore-based subsystem and a communication subsystem. The ship-borne subsystem comprises the following four parts: a first terminal device, a first function module, a first database and a first communication module. The shore-based subsystem comprises a second terminal device, a second function module, a second database, a server, a gateway, a base station and a second communication module. The communication subsystem comprises an AIS network, a 3 / 4 G network and a WiFI network. The communication subsystem is used for realizing the communication link between ships and between ships and shores. According to the technical scheme of the system, ships are dynamically grouped in the grid locating method. In this way, the communication problem among a ship-borne AIS device of a ship, a mobile terminal and a shore-based system in different network architectures can be well solved. As a result, the comprehensive supervision and the information service for the ship are realized.

Description

technical field [0001] The present invention relates to the field of ship communication, specifically, it relates to a multi-network fusion ship supervision system and data exchange method for ship-ship and ship-shore communication in combination with a routing selection algorithm using a public network and an AIS network . Background technique [0002] With the development of science and technology and the improvement of people's needs, there are more and more ways for ships in navigation to communicate with each other, and between ships and relevant departments on the shore, and the demand for the types of information exchanged is also becoming more and more abundant. [0003] AIS (Automatic Ship Identification System) is a ship and base station broadcasting system working in the VHF sea band, which can send and receive ship information such as ship identification information, ship position, latitude and longitude, course, and speed with other ships and base station AIS eq...

AI Technical Summary

Problems solved by technology

[0005] The above method has successfully established a communication link between ship-borne AIS equipment. However, according to relevant regulations, there are still some ships that are not mandatory to install AIS equipment and cannot exchange information with AIS equipment, which has caused obstacles to ship supervision and threatened the safety of ship navigation.
