Abstract

The invention discloses a large-scale base station data storage and analysis method based on distributed storage, which comprises the following steps: base station data storage: storing streaming base station data in a distributed storage system according to a base station and time; base station data conversion: combining small base station data files in the distributed storage system, calling a C + + dynamic library of RTKLIB by using a JAVA local calling technology, converting the RTCM format file into a RINEX format file, and uploading the RINEX format file to an HDFS distributed storage system and a MinIO shared storage system for storage; and the base station analyzes the data, receives the message in the message queue, analyzes the content of the message, calls an SHELL analysis script, downloads an RINEX file, calls GNSS data preprocessing software to analyze the RINEX file, outputs an analysis result and stores the analysis result into a database. According to the invention, the problems of poor data storage level expansibility and low data conversion efficiency of the base station are solved.

Description

technical field [0001] The present invention relates to the field of base station data processing, in particular to a method and system for storing and analyzing large-scale base station data based on distributed storage. Background technique [0002] In today's information age, the scale of data in all walks of life is growing explosively. Big data is a new data processing method, which has stronger decision-making power, insight discovery power and circulation optimization ability to adapt to massive, high growth rate and diverse information assets. The strategic significance of big data is not only the management of massive data, but also the professional processing of massive meaningful data, the discovery of data value, and the data-driven growth of enterprises. At present, the mainstream big data technologies on the market are based on a series of technical systems related to collection, storage, calculation, query, resource management and other functions in the Hadoo...
