Abstract

The present invention proposes an early warning method, system and chartplotter for ship collision avoidance at sea. The method includes: obtaining navigation information of the own ship, and identifying temporary obstacles to obtain identification results; obtaining at least one early warning point in the current route of the ship, wherein At least one early-warning point includes at least one of the position of the channel obstacle, the location of the historical collision accident, and the location of the temporary obstacle; according to the navigation information combined with the recognition result, it is judged whether the distance from the own ship to the current early-warning point is greater than the early-warning distance, and the judgment is obtained. As a result, the current early warning point is the shortest early warning point to the own ship among at least one early warning point; if the judgment result is no, the early warning information is generated, and the collision avoidance analysis at sea is carried out according to the current early warning point, and the handling precautions are obtained. The invention provides early warning of known dangers and unknown potential collision dangers, can reduce ship collision accident rate and collision risk, and does not increase cost price in terms of hardware equipment.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method, system and chartplotter for early warning of collision avoidance of ships at sea. Background technique [0002] In recent years, with the large-scale development of ships, the number of ships has increased rapidly, and water traffic accidents have also shown an upward trend, especially collisions between ships and ships, ships and bridge piers, ships and cross-sea cables, etc. Occurs, often causing huge losses. [0003] At present, the devices used in the field of collision avoidance between ships at home and abroad mainly include automatic radar plotting aid (ARPA for short) and automatic identification system for ships (Automatic Identification System, AIS for short). The measures taken at home and abroad for ship collision accidents are mainly concentrated on bridge anti-collision facilities (such as adding fences around bridge piers). This kind of collision avoidance...
