Abstract

We propose a marine observation system using existing light buoys to observe various marine information of marine locations. Our proposed ocean observation system is composed of the existing standard light buoy type and can be easily connected to the light buoy. The proposed marine observation system measures the mean wave height, maximum wave height, mean wave height and water temperature measured in the ocean. Besides, it can measure the air pressure, temperature, wind speed and wind speed in real time. In order to measure important peaks in marine observations, 2200 peak data are collected for 10 minutes, and the collected data are subjected to spectral analysis to extract significant wave and wave period data. The developed system removes the noise by using the filter because the marine observation system attaches to the light buoy. We compare and analyze the measurement data of the existing proven floating marine observation system and the standard equivalent system developed. Also, it is proved that the data of the standard type backbone ocean observation system developed through the comparative experiment is similar to that of the existing ocean observation system.

본 논문에서는 해양 위치에 따른 다양한 해양 정보를 관측하기 위하여 기존에 설치된 등부표를 활용한 해양관측 시스템을 제안하고자 한다. 본 논문에서 제안하는 해양관측 시스템은 기존 표준형 등부표용 형태로써 등부표에 손쉽게 연결이 가능한 구조로 구성되어 있다. 제안한 해양관측 시스템은 기존 해양에서 관측하고 있는 유의파고, 최대파고, 평균파고, 수온을 측정하며 추가적으로 기압, 기온, 풍향/풍속까지 실시간 측정이 가능하다. 해양관측에서 중요한 파고를 측정하기 위해서는 10분 동안 2200개의 파고 데이터를 수집하며 수집한 자료는 스펙트럼 분석을 통하여 유의파고와 파주기 데이터를 추출한다. 개발된 시스템은 등부표 위에 해양관측 시스템이 부착이 되기 때문에 필터를 사용하여 노이즈를 제거한다. 본 논문에서는 검증된 기존 부이형태의 해양관측 시스템과 개발한 표준형 등부표용 해양관측 시스템의 측정 데이터를 비교 분석한다. 또한 비교 실험을 통하여 개발한 표준형 등부표용 해양관측 시스템이 기존 해양관측 시스템과 데이터가 유사하다는 것을 증명하였다.
