A ship safety navigation system is provided to improve safety of a ship by sending wave information to a cabin and passenger cabins through a ship server and a communication network. A wave measuring unit is operated(S100). Radar signals which are outputted from a radar, are measured and stored in a memory(S200). The stored signal is converted to a 2D image signal. The wave information is analyzed from the image signal and the analyzed wave information is displayed(S300). The analyzed wave information is compared with an alarm setting value, and it is determined whether a dangerous wave occurs(S400). When the dangerous wave occurs, a collision value of the wave is calculated and the calculated wave collision value is compared with a collision threshold value. When the calculated collision value exceeds the collision threshold value, a navigation direction of a ship is changed(S500). The altered direction navigation path is displayed(S600). The collision value is recalculated and the recalculated value is compared again with the collision threshold value. The navigation path is repeatedly altered and the collision value is repeated calculated, until the calculated collision value is smaller than the collision threshold value(S700). The altered navigation path is displayed(S800). When the dangerous wave fades away, an alarm state is released(S900). |
