And data on wave observations for weather forecasts should be provided with accurate and real time data. However, the facility for wave observation is not only difficult to maneuver due to the nature of the installation location of the ocean, but also difficult to install, as well as to collect observation data and control the observation device. Therefore, a method of automatically recording observation data in a self-recording device, retrieving it periodically, or operating by wireless communication is generally used. In this way, it is easy to collect wave observation data from remote locations.

However, in the conventional blue observation system (blue observation system), due to the difference in the version of the system for its operation, the data storage and operation does not support the simultaneous execution function.

The wave information related to the observed observed wave may be stored in a storage unit (not shown). For example, the operating system 300 may store the blue information transmitted through the RS232C port in a binary form. The operation system 300 may share the blue information with other systems through the network 400. That is, the operation system 300 may transmit the blue information to the backup system 500 and the analysis system 600 through the network 400.

In the present invention, the network 400 may include at least one network environment mutually promised between the systems 300, 500, 600, and 700 among a wired communication network environment and a wireless communication network environment. For example, the connection between the systems 300, 500, 600, and 700 may be wirelessly connected by a wireless network using a wireless communication technology.

The spectral analysis method is a general method of analyzing irregular waves, and is very useful for analyzing irregular data. The LHM (Longuet-Higgins' Method) represents a method of estimating a wave spectrum using a Fourier series. The LHM can be applied when observing a plurality of waves at one point, such as a buoyant wave / wave height meter. Since the LHM has a high processing speed, when the observation data is large, the LHM is used as a method of presenting a representative wave and dispersion coefficient of the component wave having the maximum energy. The program that processes the wave inside the wave / wave height system provided by Datawell adopts this method. It is usually called S-file and is included in the simple analysis result transmitted by wave wave / wave height. The MEM (Maximum Entropy Method) shows very good directional resolution when observing various wave amounts at one point. The MEM is mainly applied to accurately analyze the direction spectrum of the observed wave and to obtain a two-dimensional direction spectrum. These methods are well known in the art and will not be described in detail in the embodiments of the present invention.

For example, the output system 700 may convert the image data photographed through a photographing unit (not shown) to correspond to an external transmission standard and output the converted image data through the network 400. In this case, the external output by the output system 700 may be in the form of broadcasting the captured image data, such as an Internet broadcasting system, or may be in the form of transmitting the converted image data to a specific server (weather agency, forecast-related companies, etc.) have. In an embodiment of the present disclosure, when the internal output of the analysis information is managed by the analysis system 600, the internal output function may be omitted in the output system 700.

And the detailed analysis of the wave information can be performed. Analysis of the wave information in the present invention can analyze the characteristics of the wave, wave height, period, wave direction, long period wave, and the like. The analyzed data, that is, the analysis information, is provided to the manager through the internal output, and the blue wave results can be provided in real time to an external specific server (eg, a contractor, a supplier, an overseas designer, a meteorological agency, etc.) through the external output. Then, an external specific server may predict and correct a weather forecast based on the analysis information.
