Patent ID: 8489620

Claim:
An analysis preprocessing system comprising: a data acquisition unit which acquires a data group generated by a plurality of data generation sources; a data clipping unit which clips each data from the data group acquired by the data acquisition unit; a rearrangement control unit which retains each data clipped by the data clipping unit, selects data generated prior to the corresponding data when data from a delay maximum data generation source is detected, and rearranges the selected data in order of time of generation thereof, the delay maximum data generation source corresponding to a data generation source at which a time from the generation of data to the acquisition of the data by the data acquisition unit becomes maximum; a data storage buffer which stores the data rearranged in order of time of generation thereof; an analysis data determination unit which determines an analysis data group which is a set of data used for analysis, from the data stored in the data storage buffer; and an analysis data output unit which transmits the analysis data group to a data analyzing unit for analyzing data.
