PURPOSE:To perform quantitative decision of oscillation of a ship by providing an angle and acceleration detecting means, a processing means to calculate surging displacement of a ship, swaying displacement and heaving displacement, and a display means to display a time system waveform of each displacement. CONSTITUTION:An inertia measuring device 1 comprises a magnetic azimuth sensor to detect a bow azimuth, a magnetic azimuth sensor to detect rolling, pitching, and yawing, an X, Y, Z gyro, and an accelerometer to detect acceleration in each of X, Y, Z directions. A detected signal is converted into digital data by an A/D converter 2 and the time system waveform of a measurement item is calculated by a data processing computer 3. Namely, the time system waveforms of yawing, pitching, and rolling of a ship are calculated and simultaneously, the time system waveforms of surging displacement, swaying displacement, and heaving displacement are calculated. Further, a time system waveform and the time trend of statistic is displayed on a display part 4. |
