Aqueduct special-purpose AIS system with collision avoidance early warning function and method thereof

Abstract

The invention relates to an aqueduct special-purpose AIS system with a collision avoidance early warning function. Ship automatic identification equipment acquires longitude and latitude information and current time information of a ship through a GPS positioning module; the ship automatic identification equipment is used for acquiring AIS message information of a target ship; a main controller isused for calculating the ship safety meeting distance, the ship minimum meeting distance and the ship minimum meeting time; and the main controller is used for comparing the minimum meeting distanceof the ship with the safety meeting distance of the ship, comparing the minimum meeting time of the ship with a preset safe meeting time value and sending out collision avoidance early warning according to a comparison result. The system and the method are used for safety management of inland river small ferries and have the functions of collision avoidance early warning, danger announcement and the like, provide safer and more reliable decision guidance for drivers and have the people counting function and improve the ferry sailing safety.

Description

technical field [0001] The invention relates to the technical field of inland waterway navigation devices, in particular to a special AIS system and method for ferries with collision avoidance and early warning functions. Background technique [0002] Water traffic accidents have brought huge hidden dangers to people's lives and property safety. The automatic identification system (Automatic Identification System, AIS) has strengthened the safe navigation of inland ships, and improved the safety between ships, between ships and base stations, and between ships. The exchange of information with regulatory authorities reduces the occurrence of ship collision accidents. [0003] There are a total of more than 18,000 ferries and about 22,700 ferries in my country, which play an important role in serving people's livelihood and solving the basic transportation needs of the masses, especially in economically underdeveloped areas and mountainous areas. Due to the lack of complete ...

AI Technical Summary

Problems solved by technology

Due to the lack of complete communication and monitoring support for inland river ferries, the safety conditions of ferry boats and the quality of ferry personnel are quite different. The existing AIS equipment is not suitable for small ferries due to the complicated operation. big security risk

[0004] At present, the AIS system adopts the most ship collision avoidance warning algorithm or the simplest short-distance alarm. Once the distance between the ship and the ship exceeds the set threshold, a warning will be issued. This method will weaken people's vigilance and cannot accurately identify the real danger.
