| Abstract: | Marine voyage data recorder is a kind of intelligent device of recording and preserving important information and data in ship sailing,which can collect and record data items such as commands,operation control etc.By adopting multi-port I/O multiplex technique,a compact TCP server that can provide service for multi-device is realized and the Ethernet data collection function of embedded VDR is extended,then marine VDR is successfully interfaced with main propulsion monitoring & control system and power station management system. |
