FIELD: digital transformation equipment. ^ SUBSTANCE: to increase reliability and interference resistance of electric motors with digital control due to increased trustworthiness of functioning of devices on RS-triggers, in a redundant RS-trigger, containing parallel channels from 1 to i, RS-trigger of channel i contains two inverters (3), (4), into check connections of which trigger 2 majority elements (5), (6) are introduced. Control signals are generated by means of gates with open collector. On occurrence of error, absence of signal x1 or in case of appearance of systematic error, i.e. failure of any one of inverters (3), (4) of RS-trigger of any channel (single error) due to signals of majority elements from outputs of RS-triggers of parallel channels, operating identically, the trigger is always set to same position as two neighboring ones. Suggested principle for building redundant RS-triggers is universal and useable for all devices consisting of RS-triggers, such as counters of any phase characteristic, code type, reverse counters, non-reverse counters, circular counters, etc. All variants are united by single idea, in accordance to which majority elements (5), (6) are installed in check connections of RS-trigger, allowing synchronous operation of parallel channels in case of interferences or disruption of connections. ^ EFFECT: increased efficiency. ^ 6 dwg |
