METHOD FOR DETECTING FAILED MOTION PICKUP IN EXCESS SYSTEM (VARIANTS) Russian patent published in 2005 - IPC

FIELD: automatic control systems, possibly systems with excess number of pickups such as accelerometers where fail of one pickup does not cause damage of control system.

SUBSTANCE: method comprises steps of cyclically testing mutual relation of measured motion parameters according to which failed pickup may be detected; registering time moment of disturbance of said relation; comparing readings of pickups at said time moment with calculated values while using readings of pickups in time moment previous to that of failing; detecting failed pickup according to comparison results. Method may be used at non-zero motion vector and also at zero motion vector when relation of measured motion parameters does not identify fail of pickup but comparison of pickup readings with shift signals allows to detect failed pickup.

EFFECT: enlarged functional possibilities of method.
