The future Development and Use of Voyage Data Recorder;

Based on the embedded VxWorks real-time and multi-task operating system and combined with the pattern-oriented software architecture, a realization scheme of voyage data recorder (VDR) software design is put forward.

To collect,com- press and save the audio data,one of the important function of VDR,the audio system,which bases on the Vxworks, compose three parts:audio collection,compression and saving.

VDR is an intelligent equipment which is used to record and conserve the important information and parameter of vessel during its voyaging.

For adapted the developmental market, VDR uses the design of network communication, and makes the data collection and transmission easier, also guarantees the data stream fluency and integrity; on the one side, it ensures the data security and reliability; and on this base, it can develop more the .
