초록

Recently, NMEA2000 became the de facto standard of the communication
protocol for the instrument level network in vessels, and it is anticipated that most of
the vessels will be equipped with the sensors and actuators based on this protocol. The
conventional serial communication specifications such as RS-232, RS-485, or even
NMEA0183 are single-talker/multiple-listener and interconnection among multiple
sensors and/or actuators usually results in a bundle of wires. On the other hand,
NMEA2000 is a true bus type(multiple-talker/multiple-listener) protocol and
theoretically up to 256 instruments can be hot-plugged.
With the advent of the protocol, it is necessary to consider a new type of monitoring
system for the instruments in vessels: In most traditional serial communication
environments, a dedicated monitor or user interface was necessary for each sensor or
actuator as it was simply not easy to collect data in a single place. With NMEA2000,
the collection of various types of information is simple. An embedded system can be
employed to combine, to arrange and to display informations from various types of
devices. Assuming that the actuators and sensors on a vessel are interconnected by
NMEA2000 standard, we devise a tentative interactive vessel monitoring system in
which the following 4 kinds of informations are collected and delivered: the navigation,
engine, weather and tanks informations.
