METHOD AND APPARATUS FOR MONITORING AN OPERATIONAL STATE OF A SYSTEM ON THE BASIS OF TELEMETRY DATA

摘要

A method and apparatus monitor an operational state of a telemetry data system, wherein the operational state is a nominal or a novel operation state. The telemetry data includes time series data of at least one parameter indicating the operational state. The method obtains sample interval data indicating a parameter time series data of the at least one parameter relating to a time interval duration; determines one or more characteristic quantities of the sample interval data, the characteristic quantities determined forms a sample set; obtains pre-stored sets of characteristic quantities at least one parameter and time intervals duration during nominal operation state; determines a probability sample set of characteristic quantities being outlier with respect to pre-stored sets of characteristic quantities; and if the probability exceeds a threshold, provides a message with the sample interval data and at least one system parameter or notifies no novel behaviors found.
