VIBRATION MONITORING METHOD AND DEVICE (EMBODIMENTS) Russian patent published in 2018 - IPC G01H11/06 

FIELD: metrology.

SUBSTANCE: invention relates to metrology, in particular to vibrometry. Method of vibration monitoring with a multicomponent sensor comprises stages, at which the sensor output signals are passed through the matching amplifiers and at their outputs signals vector is obtained, which is multiplied by the correction coefficients matrix, which elements are equal to the matrix elements, inverse to the multicomponent sensor sensitivity coefficients matrix, resulting vector is used for the vibration orthogonal components measurement, and the measurement results are output to the registration unit. Signals vector is multiplied by the additional correcting elements matrix, which elements are selected in such a way that product of the additional correction elements matrix and the multicomponent sensor sensitivity coefficients matrix forms matrix, which all elements are equal to ones. Signals vector, which all elements are identical to the sum of orthogonal components instantaneous values, are converted into the level estimates, which are compared with the predetermined emergency protection threshold. Device contains sensor, matching amplifiers, correction unit, vibration measurement unit, registration unit. Correction unit signals vector sum additional outputs are connected to the emergency protection unit inputs.

EFFECT: technical result is the expansion of functionality, increase in functioning reliability and accuracy.
