Distributed storage grid meteorological data reading method and system

Abstract

The invention relates to the technical field of network data reading, and discloses a distributed storage grid meteorological data reading method and system. Grid meteorological data is obtained by agrid meteorological platform. The method comprises the following steps that distributed data services are deployed at the front end of a storage server, and after the distributed data services are started, grid meteorological data types supported by the storage server are registered to a data gateway; after registration is completed, long connection is established between the distributed data service and the data gateway, and the distributed data service and the data gateway are in a synchronous connection state through a heartbeat mechanism; after receiving the grid meteorological data request parameter of the client, the data gateway reads the corresponding grid meteorological data file from the storage server; the read grid meteorological data file is converted into a data stream and returning the data stream to the client. By classifying the grid meteorological data, the client can read the grid meteorological data in a targeted manner, the data calling process can be simplified, and the data calling efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of network data reading, and more specifically, it relates to a method and a reading system for reading meteorological data of a distributed storage grid. Background technique [0002] The grid draws on the idea of ​​the power grid, and uses the Internet or a dedicated network to interconnect various geographically distributed computing resources, so that the computing resources distributed in various places are connected to each other to form a fully shared resource integration. Take the meteorological application grid as an example. It is a scientific research application grid initiated by the Chinese Academy of Meteorological Sciences and participated by many related units. Mainly develop numerical weather forecast software and its supporting software based on network technology, study the mass processing technology of observation data and numerical forecast meteorological data, and realize the remote access a...

Problems solved by technology

When a storage device is saturated with space, the historical data is transferred to another storage device to free up space to store the latest real-time grid meteorological data, and this cycle repeats, resulting in scattered distribution of grid weather and data in multiple storage devices in meteorological operations , it becomes very troublesome for users to call, reducing the efficiency of data calls
