Ship-collision avoidance guiding system using time series graphic display

Abstract

The invention relates to a ship-collision prevention system and method for preventing a collision between a ship at sea and another ship. According to the invention, provided is a ship-collision avoidance guiding system using a time series graphic display, in order to solve problems of a conventional electronic chart display and information system (ECDIS) and navigation systems using the same, which have a disadvantage of a complex and unintuitive screen display because of a simple enumeration of various pieces of information on a screen. The ship-collision avoidance guiding system using the time series graphic display displays, in a time series graph, changes in relative distance according to time with respect to respective ships and obstacles on the basis of information provided from theECDIS and a radar system, at this time, in a case of ships, whether the respective ships are on portside or starboard is displayed on the basis of radar information, and if a distance to a specific ship has a predetermined threshold value or less, the guiding system is configured to notify, through an alarm and the like, avoidance to a ship having the obligation to keep out of the way, thereby enabling the positions of an obstacle and a ship nearby at sea, crossing event time, and whether the ship is to be avoided to be easily identified at a glance, and effectively preventing a collision between ships at sea, and simultaneously, enabling a simulation for a crossing event and avoidance by inputting a random value.

Description

technical field [0001] The present invention relates to a ship collision prevention system and method for preventing a ship from colliding with other ships or obstacles during a ship's voyage, and more specifically relates to a ship collision avoidance navigation system using time-series graphic display as follows: The problem of some electronic chart display and information systems (Electronic Chart Display and Information Systems; ECDIS) of the prior art with the shortcomings of listing various information on the screen so that the screen display is complicated and not intuitive and the navigation system using it , through time-series graphs, while displaying the relative distance changes of obstacles such as ships and bridges during navigation within a specified range based on time changes, in the case of ships, the left-right positional relationship of each ship is displayed together, so that At a glance, it is easy to grasp the position, stagger time and avoidance of ship...

Problems solved by technology

[0023] The present invention is proposed in order to solve the problems of the prior art as described above. Therefore, the purpose of the present invention is to provide a ship collision avoidance navigation system that uses time-series graphic display in the following manner: The problems of some electronic chart display and information systems (Electronic Chart Display and Information Systems; ECDIS) of the prior art and the problems of the navigation system using it, which make the screen display complex and not intuitive by listing various information, pass time Sequence graphics to display the relative distance changes of the surrounding obstacles such as ships and bridges in the navigation within the specified range based on time changes. At the same time, since the left and right position relationship of each ship is displayed together, it is possible to grasp the nearby navigation at a glance. The position, staggering time and whether to avoid or not of ships and obstacles, thus contributing to rapid and accurate situation judgment
