Document Type and Number:
Japanese Patent JPH05187883
Kind Code:
A
Abstract:
PURPOSE:To enable man-power to be saved and safety to be improved by judging a safe course by a stranding danger-judging device, etc., based on navigation information. CONSTITUTION:Stranding danger judgment is made by referring to a deep line data 28 such as each broken point stranding danger which is included in a stranding danger-judgment circle with a constant radius from a their own ship position by a sea map database 4 by a position-measuring device 1 which outputs the position of their own ship and a stranding danger judging device 3. Then, a cross point between the deep line of stranding danger, etc., and the stranding danger-judgment circle is obtained by a stranding danger-judgment circle cross point operation device 29. Then, the stranding danger azimuth is obtained by a stranding danger azimuth operation device 36 based on the calculated cross point and the operation result is displayed by a stranding danger azimuth display device 40. In this manner, a safe course can be judged automatically, readily, and accurately, thus obtaining a stranding-preventive device for a ship which is superb in man-power saving and safety.
