More particularly, the present invention relates to a multi-media communication system for collecting marine weather forecasts, The present invention relates to a ship navigation support system and method for monitoring ship condition based on a multi-media communication that improves the operational efficiency of a ship by reducing the fuel cost and maintenance cost,

Currently, the maritime industry is making efforts to reduce fuel oil consumption in order to strengthen regulations on emission of greenhouse gas and air pollutants (NOx, SOx, PM) by IMO and to reduce marine profit due to continuous oil price increase. .

Concretely, most ship types are not able to improve the supply and demand conditions that have deteriorated since the financial crisis due to shipments of cargo volume increase.

In addition, the ship has a large difference in fuel oil consumption depending on the marine environment and the operating condition. For accurate analysis, it needs information on the shipyard operating experience and know-how from the operating stage, hull and linear information.

For this reason, many problems related to the utilization of ship navigation information centered on the shipyard have progressed, but the actual performance standards required by the shipping company have not been satisfied.

Accordingly, Korean Patent Laid-Open Publication No. 10-0981945 (prior art document 1) controls the multiple fuel supply device when operating the exhaust gas regulating area, creates an economical operational route that minimizes the time for operating the exhaust gas regulating area, And a method and apparatus for economic operation of a ship that supports economic operation of a ship.

In addition, Korean Patent No. 10-1401469 (Prior Art 2) discloses a method and system for collecting and managing maritime transportation information by integrating management / sharing information related to maritime transportation through a ship operation system in which a ship, a ship owner, a shipper, Discloses a method and apparatus for optimizing navigation and cargo logistics transportation processes, energy savings and minimizing greenhouse gas emissions.

In addition, in Korean Patent No. 10-0981945 (Prior Art 3), an optimal operation instruction is established in correspondence with the fixed operation information input before the operation of the ship and the variable operation information input in real time, A control method and apparatus for improving quality are disclosed.

However, in the preceding document 1, the scope of support for economic operation in the apparatus for economic operation of the ship is limited to the emission control area, and the influence of the ship operating elements is quantified, And can not support economic operation, and can not provide a solution for satellite communication reduction.

In addition, the prior art 2 has a problem that the ship's operating characteristics can not be accurately reflected because it supports only the design data and the initial commissioning data, not the actual data of the ship being operated.

In addition, although the prior art 3 can prevent unnecessary fuel waste at the time of ship operation, it can improve the economical efficiency. However, it has a problem in that it can not provide safety navigation by reducing the cost of satellite communication and setting safety flight information.

In order to reduce the communication fee caused by the transmission error, it is necessary to have the function of successive receiving and posting. The ship data to be transmitted for successive receiving and posting is stored in the database unit with information such as ID, priority, offset, data size, CRC, transmission object, transmission state (state) At the time of data transmission, the offset is shifted by the number of bytes transmitted, the size and offset of the data are matched, the CRC error is checked, and the transmission status is set to completion. If an error occurs during data transmission, data transmission is resumed from the offset to the data size in the next transmission. In the destination, data can also be received and rewound by completing the data by connecting the byte stream after offset.
