Abstract

The invention discloses a ship collision risk assessment and early warning method, a ship collision risk assessment and early warning system, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring hydrological information and meteorological information of a position where a specified ship is located, and acquiring navigation information ofthe specified ship and other ships; based on the hydrological information, the meteorological information and the navigation information, evaluating the trained adaptive ship collision risk evaluationmodel to obtain a real-time collision risk of the specified ship; determining a collision risk level of the specified ship according to the real-time collision risk; and outputting an early warning message associated with the risk level to the specified ship. According to the scheme, the self-adaptive ship collision risk assessment model is constructed, the ship collision risk is assessed by combining the regional historical information and the information during navigation, so that the assessment accuracy and the early warning timeliness of the ship collision risk can be improved.

Description

technical field [0001] The application belongs to the field of navigation science and technology, and in particular relates to a ship collision risk assessment and early warning method, a ship collision risk assessment and early warning system, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the unstoppable trend of economic globalization and the rapid development of the global shipping industry, a large number of ships have been put into waterway transportation to meet the transportation needs. The navigation waters are becoming more and more crowded, the conflicts between ships are more frequent, and water traffic accidents occur from time to time. [0003] The combination of real-time navigation risk and historical navigation conflict risk is the development trend of safe navigation of ships. Regarding the combination of historical navigation risks, some port waters have established navigation warning areas based on the spa...
