PROTECTIVE SYSTEM FOR MULTIPOLE DEVICES Russian patent published in 2001 - IPC

FIELD: cybernetics; control, monitoring, and diagnostic systems. SUBSTANCE: protective system designed to protect function of multiport outputs in the event of abnormal functioning algorithm of (n, m) device on the occurrence of failure in structure has correction unit and corrective signal shaping unit. protective gear functions to protect signal values across outputs of multiport structures and not the structures proper. Modular contactless members are used in protective system that ensure high degree (1) of functioning result confidence for device under protection at preset multiplicity of ≪ d₀≫ failures with respect to 0 and multiplicity of ≪ d₁≫ failures with respect to 1.Majority elements with logical threshold ≥ d₀+d₁ are used instead of additional- relays unit and contact matrix with diodes isolating like-polarity normally open contacts; number of majority elements equals that of outputs of multiport network that has during protection against failure multiplicity of ≪ d₀≫ and ≪ d₁≫ as many inputs as d₁+d₀+1, and one output connected to one of final elements. One input of majority element is connected to one of outputs of multiport under protection and remaining ones, to outputs of unit shaping groups of correcting signals (as many as number of multiport outputs m) that assume value 1 or 0 in step with signal value 1 or 0 across respective outputs of multiport; in this way ≥ d₀+d₁ final-element control signals can be shaped across outputs of ≪ d₁≫ ≪ d₁≫, logical-threshold majority elements irrespective of multiplicity failures occurring in multiport network and in protective system. EFFECT: improved confidence of results, speed of response, reparability; reduced power requirement, size, and mass. 3 dwg
