Abstract

La présente invention a pour objet procédé de diagnostic d'une alimentation de polarisation pour un système d'acquisition comprenant un dispositif matriciel (M) d'interface comprenant des lignes (Ligi) et des colonnes (Colj) conductrices, chaque ligne (Ligi) étant connectée à un port d'entrée (Ini) et à une alimentation (Ai) de polarisation, chaque colonne (Colj) étant sélectivement connectée à la masse (G) par la commande d'un port de sortie (Outj), et à chaque intersection, soit un circuit (Cij), soit un shunt (Sij), connectés entre la ligne (Ligi) intersectée et la colonne (Colj) intersectée, comprenant les étapes suivantes : commande d'un port de sortie (Outl) afin de relier à la masse (G) un shunt (Ski), lecture du port d'entrée (Ink) correspondant au dit shunt (Ski), un état bas indiquant une présence normale de l'alimentation (Ak), un état haut indiquant une absence anormale.
