Problems solved by technology

[0002] For data with a large amount of data, some of the existing data compression methods have insufficient compression ratios, some have low compression efficiency, and some compression methods are too complicated, and the large data model is not conducive to network transmission.
For example, meteorological data has a large amount of data due to the many elements involved and the large time span, but the existing data compression methods cannot take into account the compression ratio, compression efficiency, and accuracy requirements at the same time

Abstract

The embodiment of the invention discloses a data compression method. The method comprises the following steps: calculating a polynomial fitting function of a data set of a data file to be compressed; calculating a fitting function calculated value corresponding to each numerical value in the data set according to the polynomial fitting function; calculating a difference value between each numerical value and a corresponding fitting function calculated value to obtain a difference value set; and storing the data head of a compressed data file, the difference value set and the polynomial fitting function to obtain a compressed data file. The invention also discloses a data compression system and equipment. The data compression method and system have the beneficial effects that the data precision is not reduced, the compression ratio and the compression efficiency of the data can be improved, the data storage overhead is reduced, the bandwidth requirement during network transmission is reduced, and the data transmission under the condition of poor network conditions is facilitated.

Description

technical field [0001] The present invention relates to the technical field of data compression, in particular to a data compression method, system and equipment. Background technique [0002] For data with a large amount of data, some of the existing data compression methods have insufficient compression ratio, some have low compression efficiency, and some compression methods are too complicated, and the large data model is not conducive to network transmission. For example, meteorological data has a large amount of data due to the many elements involved and the large time span. However, the existing data compression methods cannot take into account the compression ratio, compression efficiency, and accuracy requirements at the same time. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a data compression method, system and equipment that take into account data accuracy, high compression ratio and...
