Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Take the visual simulation of different depths of Argo buoy salinity monitoring elements in a certain area as an example. The visual simulation method of Argo buoy marine products includes the following steps in turn:

[0030] Step 1: Establish a relational database layer to record the monitoring location information, marine environmental monitoring element information (release date, maintenance status) and monitoring time information of each Argo buoy; put the text of the Argo buoy into the child node under HDFS, and Relational database association.

[0031] Specifically, in this step, due to the large number of Argo buoys in the world, when using a relational database for unified management, it is necessary to use a combination of a distributed management system and a traditional relational database; the monitoring elements ...

Abstract

The invention discloses a visual simulation method for an Argo float ocean product. The visual simulation method comprises the following steps: 1) building a relational data base layer, and recording information of each Argo float; 2) rapidly reading the value of an element of a to-be-drawn ocean environment from a relational data base, and implementing three-dimensional matrix storage according two concepts of time and depth; 3) constructing a grid space with the size of m*n according to the monitored position information of the Argo float, and meanwhile, converting a geometric coordinate into Mercator projection to implement linear interpolation; 4) implementing linear interpolation on the monitored data of the element of the ocean environment in the m*n grid space according to the hierarchical organization of time and space; 5) processing the boundary of the monitored scope of each Argo float; 6) and visually rendering a three-dimensional matrix with the boundary processed through an MATLAB three-dimensional simulation method. Through the method, the section simulation of the ocean product is effectively and intuitively seen, and the method is of great significance for the research and application of the ocean environment product.

Description

technical field [0001] The invention relates to a visual simulation method of marine elements, in particular to a visual simulation method of Argo buoy marine products. Background technique [0002] Argo (Array for Real-time Geostrophic Oceanography) plans to implement a global real-time ocean observation network to detect temperature, salinity, pressure and dissolved oxygen at water depths below 2000m. At present, more than 8,000 buoys have been deployed around the world, and more than 100,000 pieces of data are generated every year. The massive amount of data has brought challenges to the three-dimensional cross-sectional visualization simulation of ocean monitoring elements. The slow reading speed and high CPU consumption during drawing will bring troubles to the application of Argo buoy marine products. At present, there is no reliable and complete visual simulation method for Argo buoy marine products. [0003] The distributed management system HDFS has the characteri...
