Sound Analysis to Develop Operation Confirmation System for Remotely-controlled Ship

In recent years, research related to autonomous and remotely controlled ships has become a major topic in the maritime field. At this laboratory, research into the field of remote control of ship operations was established in 2015.The prototype of the remote-control system has already been completed. We are studying methods and systems to support remote control. We think it is necessary to confirm that the command of the operator who operates the ship at a remote place is executed on the ship to be operated by not only the measuring instrument but also the actual measurement (ex. Sound and vibration). Since seafarers actually use sound for engine monitoring, in this study we are studying a system that analyzes measured engine sound data and calculates the actual operating conditions. In this paper, we show the result of preliminary research to detect the feature quantity from the result of analyzing the collected data of the engine sound that is given each maneuvering command.
