Problems solved by technology

However, this type of compression algorithm does not take into account the physical characteristics of industrial real-time data, the algorithm is more complicated, and the amount of CPU calculation is generally large. If these compression algorithms are used in the massive real-time data compression of industrial real-time databases, it will cause industrial real-time database systems. A series of problems such as high resource usage and reduced data query performance

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0042] Such as figure 1 As shown, it is a schematic flow chart of the lossless coding compression and decompression method of the present invention, including the following steps:

[0043] 1) Start compression, obtain a set of time-sequential data sets to be stored for an input industrial real-time data measuring point, and store the first data in the set completely;

[0044] 2) Start encoding and compressing the second data in the data set sequentially. For each data to be compressed, compress the time stamp part (seconds and milliseconds), quality part, and value part of the data in sequence, and store them in the encoded compression format:

[0045] The encoding and compression operation of a single data to be compressed is...

Abstract

The invention discloses an industrial real-time data lossless coding compression method, which comprises the following steps of: 1) collecting a group of time sequence to-be-stored data sets of an input industrial real-time data measuring point, and completely storing the first data in the sets; and 2) starting to perform coding compression on the second data in the data set in sequence, compressing the timestamp part, the quality part and the value part of each data to be compressed in sequence, and storing the compressed data in a coding compression format. According to the invention, efficient data coding compression is carried out according to the physical characteristics of the industrial real-time data, so that the transmission and storage efficiency of the industrial real-time data is higher. The system resource occupation is lower.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method for lossless encoding and compression of industrial real-time data. Background technique [0002] With the rapid development of the information age, the amount of data generated by both academia and industry is exploding. Especially in the industrial world, the scale of data collection points in the entire industrial production process continues to increase with the increase in the number of devices, usually tens of thousands to hundreds of thousands. These production data are generally collected at a sampling frequency of seconds or even milliseconds, and the amount of collected data is very large. In order to achieve efficient real-time data transmission and storage, real-time data compression is a feasible and popular solution, and a suitable compression algorithm can effectively reduce the time and space required for data transmission and storage...
