DIGITAL FREQUENCY RELAY WITH FUNCTION OF RECONSTRUCTIVE DIAGNOSTICS Russian patent published in 2017 - IPC G01P3/54 

FIELD: physics.

SUBSTANCE: device scheme comprises a short-pulse generator 1, a pulse distributor 2, the first 3, the second 4 and the third 5 and the fourth 6 RS-triggers, the first 7 and the second 8 and the third 9 status indicators, a generator 10 of the stable frequency pulses, the first 11 and the second 12 pulse counters, a reversible counter 13, the first 14, the second 15, the third 16 and the fourth 17 numerical comparators, the first 18, the second 19, the third 20 and the fourth 21 defining registers, the first 22, the second 23, the third 24, the fourth 25, the fifth 26, the sixth 27, the seventh 28, the eighth 29, the ninth 30 and the tenth 31 logic elements AND, the first 32, the second 33 and the third 34 logic elements OR, the first 35 and the second 36 logic elements NOT, the first 37 and the second 38 electronic switches, the first 39 and the second 40 memory registers, a decoder 41 and a delay element 42, the first 43, the second 44 and the third 45 output circuits, which form an output device 46, and the fourth logic element OR 47. The relay has enhanced functionality, consisting in increasing the reliability of the output information by inserting the diagnostic functions of the measuring part and the relay setting channels and by correcting the information in case of failures.

EFFECT: enhancing the functionality by increasing the reliability of the output information.
