Analysis Method for Time Series Data and Device Therefor

摘要

An analysis device for time series data from an apparatus to be diagnosed according to the present invention is characterized by being provided with an accumulation device which accumulates sensor data, operation data, or control data, obtained from the apparatus to be diagnosed, while accumulating time information, an algorithm accumulation unit which accumulates algorithms for recognizing behavior of the apparatus to be diagnosed, a behavior recognition unit which recognizes behavior of the apparatus to be diagnosed by use a recognition algorithm, and a specification unit which specifies a behavioral item to be recognized, wherein: a behavior recognition algorithm corresponding to the specified behavioral item to be recognized is selected from the algorithm accumulation unit; sensor data, operation data, or control data to be used by the behavior recognition algorithm is selected from the accumulation device; the start and end times of a selected behavior are recognized by the behavior recognition unit; and the recognized start and end times are associated with time information about data accumulated in the accumulation device, which accumulates sensor data, operation data, or control data, obtained from the apparatus to be diagnosed, while accumulating time information.
