AI Technical Summary

Problems solved by technology

AIS stipulates the reporting frequency and reporting method of ships by default. When there are a large number of ships in complex sea areas, especially near large ports, the self-organizing network system of AIS ships will generate a lot of time slot conflicts. A large number of ships The location information is lost. When the ship cannot obtain the surrounding ship information through AIS in time, the safety of navigation cannot be guaranteed, and the risk of collision is likely to occur

Abstract

The invention discloses an automatic AIS report frequency management method, and particularly relates to the field of ship communication navigation. The method comprises an automatic AIS report frequency management system which comprises a dynamic information acquisition unit, a dynamic information analysis unit, a report frequency distribution unit and a ship report configuration unit. According to the AIS report frequency automatic management method provided by the invention, automatic management of ship report frequency in a complex sea area is realized, the time slot utilization rate is improved, and the potential safety hazard of ship collision is greatly reduced; wherein the method is realized under the existing AIS framework, meets the AIS standard requirements, and solves the problems of over-high channel load and serious time slot conflict in a complex sea area; thus, the utilization rate of the AIS channel in the sea area can be obviously improved, and a powerful guarantee is provided for the safety of ships in a large-scale port.

Description

technical field [0001] The invention relates to the technical field of ship communication and navigation, and more specifically, the invention relates to an automatic management method of AIS reporting frequency. Background technique [0002] The technical field of ship communication and navigation includes AIS ship automatic identification system, which is a kind of radio communication and navigation equipment installed on ships, and is suitable for all kinds of ships such as inland rivers, ports and open seas. The AIS system is a practical system for automatic exchange of information between ships. The main exchange information includes current navigation status and ship information. The AIS technical standard stipulates that every minute is divided into 2250 time periods, and each time period can release a piece of information not longer than 256 bits. Each ship will release its own ship information by establishing a time slot table to select a time period that does not c...
