Meteorological data downloading engine and method

Abstract

The invention provides a meteorological data downloading engine, comprising a meteorological data downloading module, an information acquisition module, an integrity detection module, a management module and a storage module, wherein the meteorological data downloading module is used for acquiring meteorological background data from one or a plurality of external servers by adopting a multi-threaded downloading mode, and has a breakpoint transmission resuming function and a multi-mirror point downloading function; the information acquisition module is used for acquiring the setting information of the downloaded meteorological background data; the integrity detection module is used for detecting the integrity of the downloaded meteorological background data in accordance with the setting information acquired by the information acquisition module; the management module is used for managing the meteorological data downloading module, the information acquisition module and the integrity detection module; and the storage module is used for storing the downloaded meteorological background data. The downloading engine and method provided by the invention have the advantages of providing rich parameters, meeting different downloading demands of users, providing multiple mirror points, multithreading and support for the breakpoint transmission resuming downloading, realizing synchronous downloading by using multiple links of a file, and ensuring high downloading speed.

Description

technical field [0001] The invention relates to the field of meteorological business processing, in particular to a meteorological data download engine and method. Background technique [0002] The meteorological background field data required for the operation of the meteorological business system is immediacy. Usually, there is only a short time interval between publishing complete data on the Internet and users using the data to make real-time business system forecasts, and the background field data is usually relatively large and abundant, giving users timely It is difficult to download complete information. [0003] At present, the download tools used by most users are often single-threaded, non-breakpoint resume function software, which does not have the advantages of high speed and stability, and it takes a long time to download complete files, which cannot meet the real-time business system operation requirements. [0004] Downloading the background field data requi...

AI Technical Summary

Problems solved by technology

[0003] At present, the download tools used by most users are often single-threaded software without breakpoint resume function, which does not have the advantages of high speed and stability, and it takes a long time to download complete files, which cannot meet the real-time business system operation requirements

[0004] The speed of downloading the background field data required for the operation of the business system is slow and time-consuming, which cannot meet the time requirements of real-time business operation

[0005] The tool for downloading the background field data required for the operation of the business system is not robust, and does not have the function of resuming upload from breakpoints, resulting in incomplete download of the required data
