REDUNDANT SIGNAL PROCESSING SYSTEM, ASSOCIATED METHOD, AND AIRCRAFT EQUIPPED WITH SUCH A SYSTEM

摘要

The present invention relates to a system (12) for redundant signal processing (X1, ..., XN), an associated method, and an aircraft (2) comprising such a system, for monitoring and passivating purposes. erratic or oscillating faults affecting the sources (20) of these redundant signals. The system comprises: - a module (120) for calculating a useful current signal (U) from the redundant signals; a module (124) for monitoring / passivation, able to detect an erroneous signal, and to discard, from the calculation and according to a criterion (T), said erroneous signal; means for switching (122, 1220), as soon as an erroneous signal is detected, in a freezing mode (M2) setting the useful output signal, and to return, as soon as no more erroneous signal is detected, in a transmission mode (M1) where the current useful signal is output as the output useful signal (X).
