DEVICE FOR STABILIZATION, FAST ERECTION AND MONITORING OF POWER VERTICAL GYRO Russian patent published in 2001 - IPC

FIELD: quick leveling of the power vertical gyro platform to the plane of the local gyro horizon, and monitoring of operation of power stabilization circuit. SUBSTANCE: the device has a unit for generation of control voltages of the stabilization circuits and fast erection containing two identical circuits, each consisting of parallel-connected comparators, whose outputs are connected to the inputs of the summing amplifier, connected to whose input is a preamplifier of the longitudinal (lateral) gyro erection angle transducer. Swing sensing elements are connected to the inputs of the comparators. The output of the summing amplifier is connected via a power amplifier to the stabilizing motor. The serviceability of the stabilization circuits is monitored by a logic monitoring unit consisting of four comparators connected to a four-input OR gate, which is connected to a FAILURE analog commutator directly and to a SERVICEABILITY analog commutator - via a NOT gate by the signals of the preamplifiers connected to the inputs of the respective comparators. Operation is controlled by a selector providing for two modes of operation: fast erection with interlocking of the logic monitoring unit and power stabilization with automatic monitoring of operation of the power stabilization circuits. EFFECT: enhanced reliability and accuracy of operation of the stabilization, fast erection and monitoring systems. 2 cl, 3 dwg
