Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] In this embodiment, the mineral processing industry is monitored in real time, and there are 15 collected data items in total, including operating status data, working environment data, material information data, and alarm information data. It contains 15 numerical collection data items, specifically floating-point collection data items; 2 Boolean collection data items; 1 character collection data item, and there are three types of all states, namely: High means the upper limit is exceeded, and Low Indicates that the lower limit is exceeded, and Normal indicates that the device is normal. The cycle of collecting production data of each industrial production site is...

Abstract

The invention provides a big data compression method based on industrial processes and relates to the technical field of industrial big data analysis. This invention compresses the collected production data according to data blocks and collected data items, processes floating-point, Boolean and character-type collected data respectively according to the category of the collected data items, and determines the floating-point numerical fluctuation range and Compare changes in adjacent Boolean and character data to determine the saved data that needs to be compressed. The present invention can not only effectively improve the problem in the industrial process that the values ​​of the collected data items shift due to the increase of time, resulting in excessive deviations in the compression results, but also can reduce the size of the space occupied by the compressed collected data items and improve the compression efficiency. Enable industrial database systems to manage data quickly and effectively.

Description

[0001] Technical field: [0002] The invention relates to the technical field of industrial big data analysis, in particular to an industrial process-based big data compression method. [0003] Background technique: [0004] With the continuous development of the information industry, the amount of information in the process industry is also expanding. The number of data collection points integrated in the entire process industry usually ranges from thousands to hundreds of thousands. The data collection interval should reach the second level, and the amount of data is large. Data storage, so the data needs to be compressed. In order to enable the industrial database system to manage data quickly and effectively and improve disk storage efficiency, it is necessary to ensure that the system has a high compression rate, and to have fast and high-precision data decompression, effective data compression must be carried out. [0005] In the process industry, industrial real-time d...
