Monitoring system for an engine test bench

A monitoring system for a test bench for at least one engine component, comprising:

• acquisition means to acquire time signal packets corresponding to measurements of endogenic and exogenic parameters specific to a combination of the test bench and the engine component, at successive instants;
• processing means to construct an endogenic indicator vector and an associated exogenic indicator factor at each instant of the successive instants, using time signal packets earlier than the instant;
• the processing means to identify a context class for the exogenic indicator vector;
• and
• the processing means to calculate a risk probability of the endogenic indicator vector conditioned by the identified context class for the associated exogenic indicator vector using at least one anomaly detector, to produce a diagnostic of a state of the test bench and engine component combination.
