Abstract

The invention discloses a method and a system for analyzing data. The method for analyzing the data includes the following steps: dividing data files into a plurality of data blocks with fixed sizes, sending the data blocks into a created sharing analysis BLOCK queue in sequence through a buffering area buf, and accordingly reading and analyzing the data blocks in the BLOCK queue in sequence. The situation that load time is excessively long caused by one-time data analysis of a traditional serial analytical algorithm is greatly relieved, analysis efficiency of mass data is improved, and operation efficiency and wave form drawing efficiency of corresponding software systems are improved.

Description

Technical field [0001] The invention relates to the technical field of data processing, in particular to a data analysis method and device. Background technique [0002] With the rapid development of microelectronics technology, the power system transient recording is obviously moving towards a high sampling rate, continuous steady-state recording and mass storage. [0003] Under this trend of ocean quantification of recorded wave data, traditional analysis methods based on serial methods face great computational pressure. During the research and practice of this method, the inventor of the present invention found that The prominent contradiction can be summarized as the following two points: First, the massive comtrade data is loaded serially, which will take a long time, resulting in low efficiency of the software system; second, due to the low efficiency of drawing massive comtrade waveforms, it leads to full graphics The advanced analysis software system is unresponsive. Summ...
