A study about the ship status verification system using data signal processing

The Ship is built through various production processes, operating conditions of ship can be confirmed through various sensors. Using data of these sensors, sailors´re sailing depending on the ship condition in real-time in wheelhouse. To prepare for dangerous situation, VDR(Voyage Data Recorder) is set up on the ship by the IMO rule. That is storing the ship condition data and alarms signal for the reference second, this data is used when the ship accident happens, so this data is very important. But sailor can´t verify that wheelhouse data and VDR data are equal. If the ship accident happens, we have investigated ship situation using only VDR data. But we have no way to determine data was right in that time. In this paper, in order to improve the compatibility of ship status data through the data conversion system. In addition this system is expected to improve reliability about ship.
