Problems solved by technology

However, these data compression storage methods only compress a single data, on the one hand, they do not consider whether there is useful feature information in the data itself, on the other hand, they do not consider the correlation between different data or the mutual relationship between different data. Dependency, resulting in the loss of too much characteristic information after data compression, which cannot be recovered, which is not conducive to subsequent operations such as big data analysis or data visualization

Abstract

The invention discloses a data compression method and system for dangerous area equipment based on big data analysis. The method includes: processing the time series sequence in the equipment state set in the hazardous area to obtain the associated sequence; obtaining the prediction sequence of the associated sequence according to the historical state data, and calculating the prediction error sequence; according to the characteristic distribution density of the time series sequence in the state set, the length and The associated compression degree of each sequence in the state set is obtained by predicting the error sequence; the optimal compression scheme is obtained according to the associated compression degree of the compressed sequence corresponding to different state sets. Compared with the prior art, the present invention considers the associated compression degree of different state data, and obtains the optimal compression scheme for different state sets. At the same time, it can also accurately restore the data before the time series sequence is compressed with the compressed data, which is beneficial to the subsequent The accuracy of big data analysis or data visualization is of great significance.

Description

technical field [0001] The invention relates to the technical field of big data and data storage, in particular to a method and system for storing production data in dangerous areas for big data analysis. Background technique [0002] Chemical enterprises generally include various chemical reaction chambers, storage equipment, high-pressure high-temperature devices and other production equipment. In the production process, it is necessary to record various status data of each device in real time, such as the reaction temperature, reaction rate, and consumption rate of the reactant obtained by the sensor, the internal pressure, temperature, and mechanical vibration amplitude of the storage device, etc. status data. The various status data of each device can reflect the real-time status of the device, which can not only be used to analyze the production rate, product output, cost consumption and other characteristics of the enterprise, but also reflect whether the production ...
