FIELD: information technology. ^ SUBSTANCE: method comprises the following steps: measuring and comparing volt-time area of two half-waves of each bipolar signal of a rational frequency inductance pickup, wherein pulse generation threshold values are preset equal to Spf1=(0.3-0.75)Spr.min1 and Spf2=(0.3-0.075)Spr.min2, where Spr.min1 and Spr.min2 are the minimum permissible values of volt-time areas of the first and second half-waves of the signals, respectively; when measuring the area of the first half-wave of the signal, the obtained values of S1 are compared with threshold values of Spf1 and once the condition S1ëÑ Spf1 is satisfied, the required pulse is generated, after which during measurement of the area S2 of the second half-wave, the obtained values of S2 are compared with threshold values of Spf2, and generation of the required pulse is stopped once the condition S2ëÑ Spf2 is satisfied. ^ EFFECT: high accuracy of repeating with generated pulses the duration of the periods of signals of rotational frequency inductive sensors, simple algorithm of generating pulses. ^ 3 cl, 9 dwg |
