Abstract

The invention provides a multivariate time series abnormal mode prediction method and a data acquisition monitoring device. The method comprises the steps of obtaining an optimal k value of an MMOD algorithm based on historical data according to a natural neighbor principle; carrying out online expansion on the MMOD algorithm to achieve online identification of a multivariate time sequence abnormal mode; and according to an incremental fuzzy adaptive clustering algorithm, achieving conversion from the multivariate time series sub-sequence to the observation sequence, constructing a hidden Markov model based on a Baum-Welch algorithm and all the observation sequences, and achieving online prediction of the multivariate time sequence abnormal mode based on the constructed hidden Markov model. Through the multivariate time series data acquisition system of the cloud platform, related data needing to be mined can be better acquired, and real-time prediction of the abnormal mode of the multivariate time series can be achieved by utilizing an online density difference anomaly detection algorithm and a Markov prediction model algorithm. A monitoring system APP is constructed, so that real-time monitoring is facilitated.
