Problems solved by technology

[0003] However, when transmitting the power data of the power system, since there are many measuring points of the operating conditions of the unit in the power system, each measuring point is continuously detected and a large amount of data is generated, which makes the amount of data to be transmitted very large. Bandwidth brings a huge burden, especially under low bandwidth conditions, it is impossible to achieve efficient and reliable data transmission

Abstract

The invention provides a characteristic vector based data transmission compression method and system. The method includes that according to a vector space matrix composed of operation condition parameters of a power station unit, a minimum independent vector set of the unit operation conditions is created by computing a matrix linearly-independent set in the vector space matrix; real-time data of the unit operation conditions are classified into a plurality of classes for encoding and storing by means of clustering and division of independent information sets, a characteristic vector based data compression model dictionary of the unit is created, and then the data compression model dictionary is published in source and target servers needing communication so as to realize source data encoding and target decoding after operation condition mode recognition. Therefore, massive real-time data of the power station unit can be transmitted efficiently and reliably under the condition of low bandwidth.

Description

technical field [0001] The present invention relates to the technical field of power data transmission, in particular to a feature vector-based data transmission compression method and system thereof. Background technique [0002] In recent years, there have been more and more researches in the field of data compression, mainly focusing on telemetry data compression, medical data compression, remote diagnosis data compression, media data compression, database compression, etc. The methods of data compression can be divided into classical data compression and new data compression. Classical data compression algorithms include Huffman coding, arithmetic coding, run-length (run-length) coding, etc. [0003] However, when transmitting the power data of the power system, since there are many measuring points of the operating conditions of the unit in the power system, each measuring point is continuously detected and a large amount of data is generated, which makes the amount of ...
