Research on VDR data analysis for realization of data-based autonomous remote control

The implementation of smooth remote control between land and sea is a key goal of autonomous operation.In addition,it is also a prerequisite for remote ship control for land controllers to grasp the ship's operation status.We need to select the data required by the land controller among the multiple data transmitted and received through the wireless network environment,and find out how to deliver the selected data to the land controller.To this end,important information on ship navigation was selectively collected using the VDR log of the Korea Maritime University,and as a result of program production and analysis according to the purpose,there were three types of data that could be collected(text,video,image),and 35 types.Among them,it was analyzed that there were 10 essential data for identifying the ship operation status of land controllers,and it was found that data necessary for remote control can be extracted from VDR data.It is expected that this can contribute to the implementation of smooth remote control in the development of autonomous ship technology.
