Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Because in the prior art, data is collected by regular sampling, the collected data will be incomplete, and when data is collected by real-time sampling, the amount of collected data is very large, requiring a large amount of storage space to store data, which cannot The technical problem of reducing the storage space occupied while keeping the data intact.

[0041] In order to solve the above problems, the present invention proposes a data compression recording method, which ensures the integrity of the data by collecting data in real time, and can effectively reduce the storage space required for storing data by simply recording the data that meets the conditions. Effectively achieve the purpose of reducing the storage space occupied under the condition of completely saving data.

Abstract

The present invention discloses a data compression recording method. The method comprises acquiring data in real time, and completely recording the first acquired data, wherein the first data comprise a time value and a floating point value; for i-th data, calculating a first difference value between a floating point value of the i-th data and the floating point value of the last completely recorded data, and calculating a second difference value between a time value of the i-th data and the time value of the last completely recorded data, the initial value of i being 2; and if the first difference value and the second difference value both satisfy preset conditions, recording the first difference value and the second difference value to complete a simple record of the i-th data. The present invention also discloses a data compression recording apparatus, so that the storage space required by the data can be effectively reduced when data integrity is ensured.

Description

technical field [0001] The invention relates to the field of data compression, in particular to a data compression recording method and device. Background technique [0002] At present, when collecting data from multiple devices or multiple monitoring points, the method of timing sampling is usually adopted. The control device collects data every preset time period or collects data once at a fixed time point, and collects the collected data. Compress the data and save the compressed data. [0003] However, the method of regular sampling can only collect part of the data, and the data is incomplete. However, if the method of real-time sampling is adopted, the amount of sampled data will be too large and the required storage space will be particularly large. Therefore, how to realize the integrity of the collected data and occupy less storage space is an urgent problem to be solved at present. [0004] The above content is only used to assist in understanding the technical s...
