Method of supporting functionals in the estimation of alarm conditions in systems of vibrational monitoring
The paper presents methodological assumptions for the search for time prognoses of possible perturbations in the operation of a monitored bearing node. A way of determining the departure time of the monitored diagnostic signals from permissible areas is proposed. Its realization is determined by a solution originated from the method of ''functional supporting the availability area''. An idea of proposed estimation construction is presented on the example of a two-dimensional isothermal model of a hydrodynamic bearing.
