METHOD FOR DETECTING ATYPICAL BEHAVIOUR OF TELEMETRY PARAMETERS, AND ASSOCIATED COMPUTER PROGRAM PRODUCT AND DEVICE

摘要

The invention relates to a method for detecting atypical behaviour of telemetry parameters, comprising the following steps: dividing (220) the time interval of detection into a plurality of time windows; for each time window, calculating (230) a set of descriptors according to the measurements of said parameter in said time window, and forming an initial vector from the calculated descriptors; normalising (240) the initial vectors; for each inital vector, reducing (250) the dimension of said initial vector in order to form a reduced vector; determining the association of each reduced vector with a domain defined by a nominal behaviour boundary; and when a reduced vector is outside the domain, generating a warning corresponding to atypical behaviour of the parameter.
