NMEA 2000을 답재한 초음파 풍향 풍속계 개발에 관한 연구

Abstract

Recently NMEA 2000 protocol is familiarized as a standard real time instrument network of SOLAS Ships. NMEA 2000 is a quite different protocol from NMEA 0183 of single-talker multi- listener, which is auto configurable intelligent Plug and Play network and multi-talker, multi-listener and multi-server. So NMEA 2000 devices are easy to connect to the network and free to maintenance for network. These are the reasons why NMEA 2000 device is applied to the advanced IT ship to integrate all kinds of information on board. This paper presents a methode logy for developing a weather station which is one of core devices for navigation as a sensor of wind speed and direction using ultrasonic including temperature and barometer.

The developed system is connected to NMEA 2000 network which is composed of various kinds of merchandised NMEA 2000 device such as depth gauge, speed gauge, GPS device etc. to test connectivity with other NMEA 2000 devices and a set of functional test are carried out as weather station in comparison with another merchandised weather station developed by an advanced foreign company to ascertain usability as a weather station on board.
