Establishment of Real-time Data Acquisition and Service System of Korean Waters

Abstract

An internet information system providing several oceanographic data and meteorological data in real-time mode was established and has been operated. The data acquisition system using PCS wireless network and internet TCP/IP protocol is designed to meet the requirement of time synchronized, multi-site, real-time acquisition in ocean observation. This system use wireless internet data technology based on 1.8MHz band carrier and supported by wireless data service of LG Telecom and SK Telecom based on CDMA(Code Division Multiple Access) technology. Real-time data observed at several stations around Korean peninsula are transmitted to the data logger system of KORDI, quality controlled, and loaded into Oracle DB system.
