Key technologies and applications of hydro-observation real-time sharing

The hydro-observation real-time sharing system, synchronizing the surveying equipment, sensor, net communication and computer technology, is developed.In this paper, how to efficiently, accurately, and continuously gather and instantly share ocean hydrological data was studied on.The key techniques of hydro-observation real-time sharing, including construction of a remote surveying subsystem, mathematical modeling on data processing and intelligent analysis, and construction of a real-time dynamic sharing subsystem were detailed.All-weather, ongoing and unmanned observation, real-time and stable online data transmission, and dynamic sharing were obtained.This system has successfully applied in Tianjin Port for environment monitoring and Huanghua Port for security navigation.
