船舶在海上航行时，由于风、浪等环境因素的影响，会产生横摇、纵摇、升沉等运动。这些运动使机组人员或乘客感到不便，他们感觉到加速度的变化。因此，如果可以在船舶的特定位置测量横向和垂直加速度，就可以知道船员或乘客的不适程度。本文研制的运动监测系统由五个加速度计和陀螺仪组成的测量与通信部分和一台采集测量数据并计算运动指标的主计算机组成。MSI（运动病发病率）和MII（运动诱导的发病率）是使用测量的加速度和角速率进行真实的实时计算的。通过对韩国海事大学的“汉娜拉”号教学船的真实的实船试验，验证了所开发系统的有效性。
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.
