Ship collision avoidance method and system with integration of Internet and handheld AIS

Abstract

The invention relates to the field of the Internet and particularly relates to a ship collision avoidance method and system with the integration of the Internet and a handheld AIS. The method comprises a step of starting a built-in AIS communication module in a mobile terminal to obtain AIS data of a small ship if the small ship equipped with the mobile terminal is in an area without an Internet signal or with an instable Internet signal, and spreading the AIS data to an AIS communication module communication range; allowing a shipborne AIS terminal in the AIS communication module communication range to receive AIS data, a step of starting the built-in AIS communication module in the mobile terminal if the small ship is in the area without an Internet signal or with an instable Internet signal, and using very high frequency to communicate with the shipborne AIS terminal in the AIS communication module communication range to realized the collision avoidance of the small ship, and a step of closing the AIS communication module if the small ship is in the area with a stable Internet signal and starting an Internet AIS collision avoidance mode to realize the collision avoidance of the small ship.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and system for ship collision prevention that integrates the Internet and hand-held AIS. Background technique [0002] In the 1990s, the Automatic Identification System (AIS system for short) launched by the International Maritime Organization is a digital navigation aid system and equipment integrating network technology, modern communication technology, computer technology, and electronic information display technology. . With this device, ships can automatically obtain shore-based and other ship information, and strengthen the connection between ships and shore-based. Practice has proved that the accident rate of ships equipped with AIS is significantly reduced, and AIS can play an important role in preventing ship collisions, especially in poor visibility. [0003] The International Maritime Organization stipulates that all ships engaged in sea voyages shall be equipped...

AI Technical Summary

Problems solved by technology

[0004] However, a large number of small ships below 60 horsepower are not equipped with AIS equipment due to the limitation of cost and installation environment

At present, mobile terminals are basically equipped with GPS positioning devices to achieve ship positioning. Since the communication of mobile terminals depends on the Internet, anti-collision is achieved by communicating with AIS base stations built on the shore. Therefore, anti-collision through mobile terminals is only applicable to offshore areas. In the range of about 10 nautical miles, when the ship is in an area with no Internet signal or unstable Internet signal, the sea navigation of small ships lacks effective safety protection and risk avoidance measures
