Abstract

The invention is applicable to the technical field of data compression, and provides a data compression method and device and terminal equipment. The method comprises the following steps: acquiring atime sequence to be compressed, and converting the time sequence into a semi-continuous segment set based on a SemiConnAlg algorithm; determining a mixed segment set of the to-be-compressed data according to the semi-continuous segment set; and storing the to-be-compressed data in the form of the mixed segment set. According to the method, the optimal partwise linear approximation problem is solved, the linear time complexity is achieved, and the better execution efficiency is achieved while the optimal storage is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of data compression, and in particular relates to a data compression method, device and terminal equipment. Background technique [0002] Time series is a collection of data, in which each data point is composed of a timestamp and a corresponding data value. This type of data usually exists in the form of data streams in many real fields, such as cloud computing and medical science. Since data streams are continuously collected over time and are endless, storing such data types not only takes up a lot of hard disk resources, but also makes it more difficult to analyze these data in real time, so it is particularly important to study efficient compression storage methods. Although there are many data compression methods in the existing technology, there still exist the problems of large data occupation space and low execution efficiency during the data compression process.
