In this paper, we propose a servo-motor-based system for verifying and calibrating a device for measuring the height and direction of ocean wave. Internationally, there are many devices that measure the height and direction of ocean wave, but there is no standard data and verification device. Generally, companies develop wave measurement equipment in their manufacture, but we do not know how they produce their products. In this paper, we try to calibrate the measurement devices using two servo-motors for the wave and divergence of various devices. Each servomotor controls the wave height and the wave direction. The wave can be calibrated up to 2m and the wave direction can be calibrated in 360° direction. Besides, we develop a separate monitoring device for the calibration process which can compare and analyze the waveform in real time. Consequently, we carry out a comparative analysis experiment between the waveguide measuring device and the calibrating device. Subsequently, the accuracy of the device is confirmed by comparing and analyzing the result graph value of the comparative analyzing device. Direction is the element to confirm the direction of wave. It does not measure speed and height, but it compares and analyzes the direction values between 0°~360° direction. In addition, the verification process is conducted using the results of comparative analysis. Our calibration device can produce long-waves and short-waves of ocean wave height. Our calibrator has been designed to calibrate up to 40Kg of equipment. In South Korea, each company has its ocean wave height and calibrating device, but they can not reproduce long-wave and shortwave. Furthermore, our calibrating device can be applied to ocean wave research and various fields. |
