Research Of Digital Monitor System For Ship In Nearshore

Offshore vessel management is a focus of vessel safety management on the sea. It is calculated that among sea traffic accidents, offshore accidents (include harbor area) account for 88.3%. It can be inferred that the efficient improvement of the monitor ability and management to offshore vessels will favor the decreasing of the occurrence of the sea traffic accidents and promote sea navigation safety. That is the reason for the theme-chosen of this dissertation.The purpose of the research of the dissertation is to propose new thought on the establishment of our country's new offshore vessel digital monitor system and to provide certain theoretical basis for the establishment of the future system through research.The offshore vessel digital monitor system in the dissertation can be seen as a offshore-based vessel transport management system employing comprehensively GPS/DGPS, AIS, ECDIS and computer internet and modern communication technology. The research method is to include and handle statistics from VTS, mobile terminals and other related statistics, then through the system radio statistical telecommunication chains send them to offshore-based monitor and command center, and to show them on electronic charter board conforming to IHO S-57 standard, so as to realize the simultaneous, complete monitor, command and management of monitor and command center to navigation situation.The dissertation research focuses on mobile terminals statistics collection and management work, radio statistics transmit platform, system display and application platform. Its main achievements are regulating transferred statistics formation within system and establishing system display platform based on electronic charter.The dissertation research suggests that the theoretical basis, the technical basis and the approach to realize the establishment of the offshore vessel digital monitor system of our country on its own are basically founded and the establishment of similar monitor system is completely applicable.
