초록

바다에서 운항하는 선박은 바람과 파도 등의 외란 때문에 횡동요(Rolling), 종동요(Pitching), 상하동요(Heaving) 등의 운동을 하게 되며, 이러한 운동은 가속도 형태로 승객이 느끼게 된다. 따라서, 선박내의 특정 지점에서 좌우방향, 상하방향 가속도와 각속도 등을 계측하면 선원 또는 승객이 선박 운동에 어느 정도 피폭되었는가를 알 수 있다. 본 연구에서 개발한 운동 운항환경 모니터링 시스템은 4개의 가속도계와 가속도계, 자이로가 포함된 관성 자세계측장치, 데이터 취득장치를 포함한 계측 및 통신부, 중앙에서 데이터를 관리하고, 운항환경 지수를 계산하는 전산기로 구성되고, 계측된 가속도와 각속도를 이용하여 운항환경을 나타내는 정량적 지수인 뱃멀미 지수(Motion Sickness Incidence, MSI), 운동유발 작업방해회수(Motion Induced Interrupt, MII)를 실시간으로 계산한다. 개발된 시스템은 한국해양대학교 실습선인 한나라호의 부산-목포, 부산-제주 연안항해시 실선시험을 통하여 유효성을 확인하였다.

A ship in a sea cruises with rolling, pitching, heaving etc because of environmental causes such as wind and wave. Those motions make crews or passengers feel inconvenience and they feel acceleration changes. Therefore, if lateral and vertical accelerations can be measured at a specific position in a ship, it can be known how discomfortable crews or passengers are. The motion monitoring system developed in this paper consists of measuring and communicating part including five accelerometers and gyro and a main computer which acquires measuring data and calculates motion indices. MSI(Motion Sickness Incidence) and MII(Motion Induced Interrupt) are calculated in real time using measured acceleration and angular rate. The validity of the developed system was confirmed through the real ship test of Hannara which is the school ship of Korea Maritime University.
