Embodiment Construction

[0044] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0045] Such as figure 1 As shown, a distributed time series geographic information service system includes a data acquisition module, a data storage module, and a data query module. The data acquisition module is used to process data in distributed automatic weather stations in a message queue. The data storage module is used to store the data collected by the data collection module in a time series using a distributed non-relational database; the data query module is used to distribute Multiple processes independently interact with the data storage module to realize scalable query services.

[0046] The system of the present invention also includes a data analysis module, which is used to directly analyze the data stored in t...

Abstract

The invention relates to a distributed time series geographic information service system and method. The system comprises a data acquisition module, a data storage module and a data query module, wherein the data acquisition module is used for acquiring data in distributed automatic meteorological stations in a message queue manner; the data storage module is used for carrying out columnar storage on the data acquired by the data acquisition module in a time series form through a distributed non-relationship type database; and the data query module is used for independently interacting with the data storage module by adoption of a plurality of distributed processes so as to realize a flexible query service. According to the system and method provided by the invention, through a process of realizing the data acquisition, storage and query, simple and high-availability data services more suitable for meteorological data can be provided for the clients.

Description

Technical field [0001] The invention relates to the application field of meteorological science and big data technology, and in particular to a distributed time series geographic information service system and method. Background technique [0002] Due to the huge base of automatic weather stations, each automatic station generates data every minute, and the data is becoming increasingly large. The use of dedicated relational databases to maintain this level of data costs is quite high; there are also plans to use distributed solutions to solve the problem of data storage, but it still requires a lot of research and development efforts for data samples. At present, the technical solution in this technical field that is relatively close to this proposal is to address the problem of traditional centralized data storage and single-point query. It provides a storage and retrieval method based on massive meteorological data, using the Hadoop platform, and distributing non-relational da...
