METHOD AND SYSTEM FOR TRAINING ACOUSTIC OR VIBRATION ANALYSIS OF MACHINE Russian patent published in 2019 - IPC G05B23/02 G06F11/34 G01H17/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to a method and a system for analyzing the state of operation of a machine, such as an aircraft engine. To analyze the state, training is carried out to provide a reference data base on data of threshold values characterizing operation of the machine, for which signals are received, which are characteristic for normal operation of the machine, and signals characteristic for abnormal operation of the machine, a deviation signal is calculated, based on which the status indicator is calculated and the threshold value of the indicator value is registered in the reference data base. System comprises a module for receiving a signal supplied by a sensor connected to the machine, a reference database, a module for calculating deviation signals, a module for calculating indicators, a module for determining threshold values of indicators, configured in a certain way.

EFFECT: higher quality of machine state determination at testing stage.
