Industrial data compression method and system, storage medium and terminal

Abstract

The invention belongs to the field of industrial big data, and particularly discloses an industrial data compression method and system, a storage medium and a terminal. The method comprises S100, acquiring equipment data required by a user, and converting the equipment data through a BWT algorithm to obtain integer digital throttling of the equipment data, S200, carrying out wavelet transformationon the integer digital throttling, designing a wavelet coefficient tree, constructing a wavelet coefficient table, and writing parameters in the modeling process of the wavelet coefficient table intoa model parameter table, S300, introducing the wavelet coefficient table and a position mask table into embedded zero-tree coding to generate a main scanning symbol table and an auxiliary scanning symbol table, S400, performing Huffman encoding on the one or more main scanning symbol tables generated in the step S300 in combination with the model parameter table, and outputting an encoded code stream, and S500, writing the code stream into a two-dimensional code of a numerical control system to complete compression of the equipment data. The industrial data compression method provided by theinvention has a high compression ratio on the premise of no data distortion.

Description

technical field [0001] The invention belongs to the technical field of industrial big data, and more specifically relates to an industrial data compression method, system, storage medium and terminal. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, which refers to a huge network formed by combining various information devices with the Internet. At present, industrial equipment mostly transmits data in real time through wired networks, wireless networks or mobile networks. These industrial data transmission methods have great disadvantages: 1) Due to the complexity of the industrial environment, signals from wired networks, wireless networks or mobile networks The fluctuation is large, and the equipment is disconnected due to the influence of the environment. Once the industrial data is lost, it cannot be reproduced, and the data integrity is poor; 2) The hardware of some industrial equipment does not ...
