Abstract

The invention is applicable to the technical field of data compression, and provides a data compression method, device and terminal equipment. The method includes: obtaining a time series to be compressed, and converting the time series into a semi-continuous segment set based on the SemiConnAlg algorithm; determining a mixed segment set of the data to be compressed according to the semi-continuous segment set; The data to be compressed is stored in the form of the mixed segment set. The invention solves the optimal piecewise linear approximation problem, has linear time complexity, and has better execution efficiency while ensuring optimal storage.

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. Contents of the invention [0003...
