Adaptive compression and lossless fast transmission method and system of high-frequency test data

Abstract

The application discloses a kind of high-frequency test data's adaptive compression and lossless fast transmission method and system.The method includes: real-time extraction of high-frequency test data multidimensional dynamic feature vector and mark feature point;Based on feature, network bandwidth and target compression ratio, through pre-training decision model dynamic selection compression algorithm combination and parameter;According to algorithm combination, data is framed and type is preprocessed;With multistage pipeline execution compression, and interstage insertion based on statistical characteristics correction link;Three-dimensional transmission state matrix is constructed, which fuses priority, link and quality score, dynamically allocates link and adaptively adds forward error correction code;After error correction decompression at receiving end, lossless verification is realized by multidimensional comparison of the feature point sequence of reconstructed data and original data.The application realizes the whole process adaptation of compression strategy and transmission scheduling, improves the compression and transmission efficiency while ensuring the lossless and reliable recovery of data.
