Patent Searching and Data


Title:
DATA ANALYSIS DEVICE
Document Type and Number:
Japanese Patent JP2017053309
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for obtaining time series data varying as time elapses from a detected signal of a sensor and appropriately analyzing characteristics of the time series data.SOLUTION: A data acquisition unit (S400) obtains time series data varying as time elapses from a detected signal of a sensor. A differentiation unit (S402) differentiates time series data obtained by the data acquisition unit. A moving average unit (S404) calculates a moving average of a result of differentiation generated by the differentiation part differentiating the time series data. A determination unit (S410) determines a wave-shape of the time series data on the basis of the moving average calculated by the moving average unit. The data analysis units (S412 to S418) analyze characteristics of the time series data on the basis of the wave-shape determined by the determination unit.SELECTED DRAWING: Figure 2
