Combined internet and handheld AIS (automatic identification system) marine anti-collision method and system

Abstract

The invention relates to the field of internet, in particular to a combined internet and handheld AIS (automatic identification system) marine anti-collision method and system; the method comprises: if both a first small ship carrying a first mobile terminal and a second small ship carrying a second mobile terminal are in an area with no internet signal or with instable signal, starting a first AIS communication module built in the first mobile terminal and a second AIS communication module built in the second mobile terminal so that the first AIS communication module acquires first AIS data of the first small ship and broadcasts the first AIS data to a communication range of the first AIS communication module; when the small ships are in the area with zero internet signal or with instable internet signal, starting the first AIS communication module to use very high frequency to communicate second mobile terminals of other small ships in the communication range of the first AIS communication module so that collision of the small ships is prevented.

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
