SHIP STEERING ASSIST DEVICE FOR ESCAPE NAVIGATION

摘要

PROBLEM TO BE SOLVED: To provide a recommended deceleration pattern to a mate and to avoid the danger of clashing to as to contribute to safe traveling if the danger of clashing with another ship occurs during traveling in a region in which steering is impossible. ;SOLUTION: A clash preventing device 1 measures TCPA(time from a closet point to a clashing danger ship) for other ships, DCPT(distance from a closest point to the clashing danger ship), direction and distance from the self ship and the course and the speed of other ships. A clash avoidance planning device 6 makes a clash avoidance plan based on data for the other ships from the clash preventing device 1, a self ship position from a position measuring device 2, a ship speed from a speed meter 3, a ship bow direction from a gyro 4 and a self ship closing circle radius value (r) inputted from a key board 5, if the plan can be made, provides the recommended deceleration pattern as the result of processing to a navigation officer by displaying the same on a display device 7, and if the plan cannot be made, sends data to an alarm producing device 8 and produces an alarm. The mate steers the ship according to the deceleration pattern displayed on the display device 7, avoids clashing with another ships and thereby navigates the ship safely.;COPYRIGHT: (C)1997,JPO
