When the present invention is not secure sufficient sight distance due to the dense fog offshore, the present invention relates to a ship-of-sight between risk warning system to prevent collisions between ships.
Viewing distance server of the vessel cross-line-of-sight danger alarm system line-of-sight sensor 10 for measuring the visual range of a point doubling is located in the vessel, GPS module 12 to know the location of the ship, road traffic control system according to the present invention ( visible terrestrial control system using a computer) is mounted, a satellite communication module in the line-of-sight client 16 of the vessel) 20 and the satellite communication module 14 and the stored visual range client ID of the vessel (16 for communicating with the ship's ID to the distance server 20, position coordinates of the vessel, and the line-of-sight GPS coordinate distance from the sensor 10 of sight server 20, the land-control system by transmitting the measured line-of-sight by the calculation client-sight of calculating the distance (d1) between the vessel and through extracting vessel the following interval setting to be passed to the location and ID of a peripheral vessel to client-sight (16) of the vessel, the vessel Characterized in that the warning to the risk in the tree (16).
