Embodiment 1

[0050] This embodiment discloses a numerical data compression method based on bit-by-bit variable-length storage, which compresses and decompresses data by analyzing the binary storage format of the data, so as to reduce the amount of time series data and solve the problem of insufficient data storage capacity. In the process of integer data compression, from the high bit to the low bit, the storage bits that are consecutively 0 in the binary storage unit are removed, and only the effective bits containing 1 are stored; in the process of floating-point data compression, according to the actual size and precision range of the value, Implement drop storage. Based on the above ideas, the numerical and string data can be stored with variable length. No matter how the data precision of the database is set, they can be stored according to the minimum length to realize data compression processing; during the decompression process, there is no need to associate up and down, only need t...

Abstract

The invention provides a numeric data compression method based on bitwise variable-length storage. The numeric data compression method comprises the steps: judging the data type of to-be-compressed data; querying a memory binary storage mode of the to-be-compressed data, judging whether the adjustment of the length of the data type unit meets a compression condition or not, and determining the to-be-compressed data again; performing variable-length storage on the to-be-compressed data so as to store the to-be-compressed data according to the minimum length, and achieving data compression processing: in the integer data compression process, removing continuous 0 storage bits in the binary storage unit from a high bit to a low bit, and only storing 1-containing valid bits; in the floating point type data compression process, carrying out bit reduction storage according to the actual size and the precision range of the numerical value. By means of the storage mode of the data in the computer, bit-by-bit variable-length storage is achieved, up-down associated information and other key information between the data do not need to be considered, compression bits do not need to be stored,and compression storage can be achieved to the maximum extent on an existing storage structure.

Description

technical field [0001] The disclosure belongs to the technical field of electric power sequential data compression, and in particular relates to a numerical data compression method and system based on bit-by-bit variable-length storage. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of electric power informatization, a large amount of business data has been accumulated in the long-term operation. At the same time, business operations urgently need to obtain more and more valuable information from the vast amount of data. Therefore, electric power big data technology is widely used in the electric power industry. It has received extensive attention and vigorous development. Due to the continuity of power production, the number of real-time data collection points usually ranges from thousands to hundreds of thousands,...
