ANALYSIS METHOD OF TIME SERIES DATA AND ABNORMALITY MONITORING DEVICE OF TIME SERIES DATA

摘要

PROBLEM TO BE SOLVED: To detect transition of a dynamical system of time series data by a trajectory parallel measure method.;SOLUTION: An analysis method of time series data for analyzing the time series data obtained from a monitoring and control target by a trajectory parallel measure method includes: embedding the obtained time series data in an n-dimensional state space to calculate a trajectory parallel measure; performing moving average processing on the time series data of the calculated trajectory parallel measure; and detecting transition of a dynamical system that occurs in the time series data based on an increased value of the trajectory parallel measure in the time series data of the trajectory parallel measure after the moving average processing.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
