Patent ID: 8886582

Claim:
A system for detecting and locating failures in a complex system, comprising: at least one sensor (CAP) for delivering a signal (S CAP ) representing the functioning of a component (COMP) of said complex system; at least one module (MOD VAL ) validating the proper functioning of said at least one sensor (CAP) capable of analysing and comparing said signal (S CAP ) and of delivering: at least one validated signal (SIG VAL ) associated with a first order confidence level (NC 1 ); or a message (MSG CAP ) representing a failure of said at least one sensor (CAP); a failure detection module (MOD DP ) capable of detecting a failure affecting at least one sub-system (SS 1 , SS 2 ) or a component (COMP) from said validated signal (SIG VAL ) and, if it is the case, of generating at least one raw failure message (MSG PB ) comprising raw information (INF PB ) on said failure and a second order confidence level (NC 2 ); a data merging module (MOD FD ) which, at least from said raw failure message (MSG PB ) or from said message (MSG CAP ) representing a failure of at least one sensor (CAP), is capable of generating a consolidated failure message (MSG PC ) comprising consolidated information (INF PC ) on a failure affecting at least one sub-system (SS 1 , SS 2 ) of said complex system (SC) and a third order confidence level (NC 3 ); and a decision-making module (MOD PD ) capable of obtaining said consolidated failure message (MSG PC ) from a database and of deciding at least one corrective action in relation to the diagnosed failure that is to be taken in relation to: said consolidated information on a failure (INF PC ); said third order confidence level (NC 3 ); and a level of seriousness (NG) of said failure.
