METHOD OF MULTICHANNEL PROXIMATE DIAGNOSTICS Russian patent published in 1999 - IPC

FIELD: automatics, computer engineering. SUBSTANCE: method refers to diagnostics of condition of object by results of conversion of determined and random signals. It can be used in telemetering systems with evacuated information storage ( black box ) and radio channel to transmit distress failures. Technical result of invention lies in increased information usefulness of READING of each signal thanks to construction of operation ANALYSIS in time region. In accordance with method of multichannel proximate diagnostics integration of signals into groups by characteristic signs is optimized. Input signals in groups are connected in turn for the time of formation of standard levels with specified frequency, coordinates and standard level of each signal are stored in digital code and with them next cycle is continued and moment sqn du/dt of change of sign of first derivative of signal is isolated. Moments sq. du sqndu^o/dt/dt of change of sign of first derivative of envelope of signal by isolated moments sqn du/dt of change of sign of first derivative of signal are determined. In addition moments sqn du sqndu^t/dt/dt of change of sign of first derivative of modulating signal by time coordinate are selected and data flow is coordinated with its output to communication channel. EFFECT: increased information usefulness of each signal. 2 cl, 6 dwg
