Ship collision avoidance method using psychological character of ship officer

Abstract

The present invention relates to a ship collision avoidance method using a psychological character of a ship officer, including calculating a relative distance (RD) and a relative bearing (RB) betweentwo ships by using information of a main ship and information of an opposite ship; estimating the relative distance (RD) and the relative bearing (RB) by using a collision risk (CR) perception of theship officer, converting the estimated results to three-dimensional (3D) coordinate data and modeling a Collision Risk Estimation Model (CREM); calculating a collision level (CL) using a distance ofa ship domain (DSD) and the modeled Collision Risk Estimation Model (CREM); deciding a reference value of a spatial aspect corresponding to a reference distance for determining a presence of a collision risk between two ships and a reference value of a psychological aspect corresponding to a collision level (CL) for determining a presence of a collision risk between two ships; comparing the relative distance (RD) with the reference value corresponding to the spatial aspect, so as to generate a ship domain (SD) warning , or comparing a collision risk corresponding to the relative distance (CL(RD)) with the reference value corresponding to the psychological aspect, so as to generate a collision risk (CR) warning.

Description

technical field [0001] The present invention relates to a method for avoiding collision of ships utilizing the psychological characteristics of seafarers, which can help avoid ship collisions by utilizing the psychological characteristics of seamen to the risk of collision in order to prevent the occurrence of marine accidents. Background technique [0002] At present, ships use a variety of electronic navigation equipment such as ARPA / Radar (Automatic Radar Plotting Aids / Radar), ElectricChart Display and Information System), and AIS (Automatic Identification System) to detect ship collisions. [0003] The prediction of collision risk between ships is based on the Ship Domain theory and uses the distance at Closest Point of Approach (DCPA) and Time to the Closest Point between ships. of Approach, TCPA). [0004] There are many remaining problems in the collision avoidance method using ship domain theory and DCPA and TCPA, which have not been solved yet. [0005] Also, vari...

AI Technical Summary

Problems solved by technology

[0011] However, the research on the human error of OOW in the prior art is only mainly on the cause of human error and the research on classification accounts for the majority, but there is no research on ships applied to actual sea navigation.

The reason for this is that it is very dangerous and difficult to conduct tests on ships and OOW that are actually sailing at sea, and the test costs are expensive

For this reason, no research has been done to apply OOW-aware CR to collision avoidance or collision prevention for actual ships
