A ship collision risk early warning method integrating geometric analysis and data mining

Abstract

The invention discloses a ship collision risk early warning method that integrates geometric analysis and data mining, comprising: combining ship AIS data with a quaternary ship field modeling idea to construct a forbidden boundary and an expected boundary in the quaternary ship field. Then, according to the quaternary ship domain model, the ship collision space risk and early warning value are obtained, and the ship collision time risk early warning value is calculated according to the ship collision space risk; the ship collision time risk is obtained by using the instantaneous relative position of the ship. Finally, according to the catastrophe theory, the space-time collision risk and early warning value of two ships are calculated respectively, and the calculation model of space-time collision risk of any ship and early warning value of space-time collision risk of any ship under the multi-ship encounter scenario is constructed. Use edge computing to quickly compare the space-time collision risk of ships and the early warning value of space-time collision risk of ships, and provide support for ship safety supervision and collision avoidance decision-making. This method can not only support ship collision avoidance decision-making and maritime safety supervision, but also reduce and avoid ship collisions and ensure water safety.

Description

technical field [0001] The invention belongs to the field of water traffic safety, and in particular relates to a ship collision risk early warning method which integrates geometric analysis and data mining. Background technique [0002] In recent years, with the promulgation and implementation of major strategic decisions in the field of national water transport, water economic activities have become increasingly frequent, and the frequency of water dangers and accidents has also continued to increase, which has aroused widespread national and regional attention to water transport safety, making the country Countries and regions have put forward higher requirements for emergency response capabilities, coordination capabilities, and handling capabilities for water emergencies. With the development of smart ships and smart maritime technologies, early warning of ship collision risk is playing an increasingly important role in ship collision avoidance and maritime traffic mana...

Problems solved by technology

However, the application of the calculation of ship collision risk in the ship field is mainly based on the azimuth and distance of other ships entering the ship field of the ship. Few of them calculate the ship collision risk and issue an alarm based on the space-time elements in the ship field.
