Abstract

Se desvelan un sistema y un procedimiento de monitorización de estado y de identificación de firma de fallos de un sistema. En una realización, el sistema estima el Índice de Estado (HI) del sistema como datos de series temporales. Mediante el análisis de los datos correspondientes al HI estimado, el sistema identifica una o más ventanas de tiempo en las que la mayoría de los valores de HI estimados son bajos, como una ventana de HI bajo y una o más ventanas de tiempo en las que la mayoría de los valores de HI estimados son altos, como una ventana de HI alto. Tras la identificación de una ventana de HI bajo, que indica un comportamiento anormal del sistema que se está monitorizando, el sistema, en base a una red bayesiana local generada para el sistema que se está monitorizando, genera un Índice de Explicabilidad (EI) para cada sensor, en el que el EI cuantifica la contribución del sensor al HI bajo. Además, los componentes asociados se identifican como contribuyentes al comportamiento anormal/defectuoso del sistema.
