Abstract

The invention discloses a power grid data lossless compression method and device. The method comprises the following steps of processing the acquired original data, and determining the acquisition precision and/or sampling frequency of a single sampling point; extracting a feature field corresponding to the number of each compression sub-algorithm according to a plurality of preset compression sub-algorithms, the feature field being a single sampling point or all sampling points describing one cycle; according to the feature field corresponding to each compression sub-algorithm and the data width of the feature field, determining a compression ratio obtained when the original data is processed by each compression sub-algorithm; according to a preset target compression ratio, determining a target compression sub-algorithm matched with the target compression ratio; and processing the original data according to the target compression sub-algorithm and the corresponding feature field, and generating a feature sequence and a supplementary description data sequence. According to the method, the bandwidth occupation time of a transmission channel is reduced, and the transmission efficiency is improved, and the low-speed and high-efficiency transmission is facilitated.

Description

technical field [0001] The invention belongs to the technical field of data compression, and in particular relates to a lossless compression method and device for grid data. Background technique [0002] At present, most of the equipment processing grid data does not compress the grid data when transmitting the grid data. Therefore, the transmission burden on the transmission channel is heavy and the transmission efficiency is low. [0003] Especially when the devices use their respective local interfaces (such as serial port, FireWire, GPIB, USB, etc.) rate), thereby increasing the power consumption of the device. In addition, in some scenarios, increasing the communication rate of the local interface will reduce the anti-interference capability of the device. Contents of the invention [0004] The invention provides a method and device for lossless compression of grid data to overcome the problems of large data volume and large power consumption of transmission equipme...
