The application provides a kind of
data transmission system and method of ship, it is related to ship communication technical field.The
system includes
data acquisition module, for collecting the navigation data of ship;
Data processing module, for the initial data obtained by
data acquisition module is washed and is denoised and is segmented, and generates redundant
tail packet, to redundant
tail packet and data block are multilayer FEC coding, then all data packets are integrated;
Data transmission module, for selecting the optimal
communication link and carrying out
data transmission;
Shore end receives and
data analysis module, for receiving the new data packet transmitted by
data transmission module and carrying out decoding
recovery, and recovering the lost data;Feedback
processing module: for feedback information, and to
data processing module and data transmission module transmission adjustment strategy, by real-time monitoring link state and selecting optimal
communication link, combined with dynamic adjustment FEC coding rate and
bandwidth management strategy, ensure the stability and efficiency of data transmission.
