MULTIPOLE LOGICAL-THRESHOLD MODULE Russian patent published in 2001 - IPC

FIELD: cybernetics; control, monitoring, and diagnostic systems. SUBSTANCE: logical-threshold multipole module provided with n inputs (control windings of relay unit) and triangular contact matrix with n outputs functions to shape control signals for group of final elements which are thrown in operation only after preset logical operating threshold is shaped for particular final element. Input control pulses (binary signal trains) are applied to module inputs and reliable final-element control signals are shaped across matrix outputs corresponding to different levels (ranks) of logical thresholds capable of withstanding in some cases random and systematic failures of module structure components. Really unit and triangular contact matrix provide for shaping final-element signals with preset operating thresholds of confidence 1.Contact matrix is, essentially, bridge structure (class H) described for each of its outputs by set of symmetrical Boolean functions implemented by voting schemes. Triangular contact matrix is built around normally open contacts of module relay unit arranged in tiers with one contact number descending among columns; like-polarity diagonally opposite contacts are isolated by diodes. Two adjacent contacts of any column as well as mid-point of two series-connected matrix diodes form nodes. Shaped across output nodes of each line of matrix are final-element control signals with low level of logical threshold corresponding to sequence number of contact matrix output. Upper tier of matrix is assembled of normally open contacts of all n relays and is connected to plus bus of power supply. Lower tier terminates in one make contact of relay ≪ X_n≫; shaped across output of the latter is signal with = n-level operating threshold. Relay unit has X₁,X₂,X₃,...X_n control windings connected to plus bus of power supply. Applied to inputs of control windings are pulses where X_i ∈ 0,1. EFFECT: provision for using proposed modules of high-degree readiness in nuclear power engineering and sophisticated space and rocket engineering systems. 3 dwg
