system for diagnosis of damage of two-tier falownika tension, characterised by the fact that it is equipped with demultiplekser (1), which is a signal corresponding to the sector number entry tension (ns) plane. - beta, which currently is blunt vector voltage of stojan us, where the output signal (s1) is demultipleksera sector 1, sector (s2) - 2, - 3 (s3) sector.(s4) - sektora4 (s5) - sector 5 and (s6) - sector 6, each step (s1), (s2), (s3), (s4), (s5), (s6) multipleksera (1) is the one of measurement systems, respectively, (2), (3), (4), (5), (6), (7) and each of the output signals of the measuring systems (2), (3), (4) ), (5), (6), (7) is one of the hits of one system sharing, respectively (8), (9), (10), (11), (12),(13), which are connected with the second entry exit block speed (14), which is the measured angular speed signal of engine. and exit systems of (8), (9), (10), (11), (12), (13) are connected to the track gauge each of transistors which constitute two sets of komparatoru00f3w, respectively (15), (16), (18), (19), (23), (24), (26), (27), (31), (32), (34), (35),(39), (40), (42), (43), (47) and (48), (50), (51), (55), (56), (58) and (59), with which both comparators in the first couple komparatoru00f3w (15), (16), (23), (24), (31), (32), (39), (40), (47) and (48), (55), (56) in the measurement of the output transistor is connected with the first arms mnou017cu0105cy me, respectively (17), (25), (33), (41), (49), (57),the way each first komparatora in second pair komparatoru00f3w (18), (23), (31), (39), (47), (55) in the measurement of the transistor is connected to one of the two latter systems in proliferation, respectively (21), (29), (37), (45) (53), (61), and the way each the second komparatora him in another couple komparatoru00f3w (19), (27), (35), (43), (51).(59) in the measurement of the transistor is connected through the absolute value measurement of the transistor circuit blocks, respectively (20), (28), (36), (44), (52), (60) to a second of the two latter systems in proliferation, respectively (21), (29), (37) (45), (53), (61), and action and the first of proliferation, respectively (17), (25), (33), (41), (49),(57) together with other systems of proliferation, respectively (21), (29), (37), (45), (53), (61) are connected to the sections size respectively (22), (30), (38), (46) and (54), (62).a diagnostic falownika transistors, characterised by the fact that in measurement systems, respectively, (2), (3), (4), (5), (6), (7) is measured while the raised voltage vector of stojan in individual sectors combined plane? - beta, and converts the measured time value proportional to the tension, after which the systems sharing, respectively (8), (9),(10), (11), (12), (13), divides the signal corresponding to the voltage vector being raised tension in the various sectors of stojan plane double? - beta by tension corresponding to signal speed, by what is normalised signal value napiu0119ciowego time (tm1), (tm2), (tm3), (tm4), (tm5), (tm6) using knowledge of measured engine speed. ,and then in the second komparatorach each pair of komparatoru00f3w in the measuring of the transistor (16), (19), (24), (27), (32), (35), (40), (43), (48), (51), (56), (59) compares the result sharing with the established threshold value voltage arbitrarily, proportional to this time, kt u00f3rej crossing indicates damage specific transistor falownika,at the same time, in the first komparatorach each pair of komparatoru00f3w (15), (18), (23), (26), (31), (34), (39), (42), (47), (50), (55), (58) compares the result of common signal reference, after results comparisons with both komparatoru00f3w each first pair are multiplied in the first block mnou017cu0105cym, respectively (17), (25), (33), (41), (49), (57),the results of comparisons of the first and second pair of komparatoru00f3w each komparatoru00f3w multiplied in other systems a proliferation, respectively (21), (29), (37), (45), (53), (61) with the signal absolute value signals with each other komparatora other couples komparatoru00f3w that obtains in the absolute value, respectively (20), (28), (36), (44) (52) (60).after the signals of the first systems proliferation (17), (25), (33), (41), (49), (57), combining with the other systems, proliferation, respectively (21), (29), (37), (45), (53), (61) czu0142onach size respectively (22), (30), (38), (46) and (54), (62), and then on the basis of non-zero it concludes by aggregation of the failure test by measuring the track of a transistor.
