Title (EN) METHODS AND SYSTEMS FOR FAULT DIAGNOSIS
(FR) PROCÉDÉS ET SYSTÈMES DE DIAGNOSTIC DE DÉFAILLANCE
Abstract:
(EN) A control system (120) and methods implemented on the control system (120) are disclosed. The control system (120) includes a tuning/detuning system and a diagnosis system. The tuning/detuning system includes a first voltage source (210), a second voltage source (220), one or more coil arrays (290), and one or more tuning/detuning circuit drivers (280) corresponding to the one or more coils arrays (290), respectively. The diagnosis system includes a first current sampling circuit (131) and a processor (132). The first current sampling circuit (131) is configured to obtain a first current. The processor (132) is configured to diagnose the tuning/detuning system based on the first current.
(FR) L'invention concerne un système de commande (120) et des procédés mis en œuvre sur le système de commande (120). Le système de commande comprend un système d'accordage/désaccordage et un système de diagnostic. Le système d'accordage/désaccordage comprend une première source de tension (210), une seconde source de tension (220), un ou plusieurs réseaux de bobines (290) et un ou plusieurs pilotes de circuit d'accordage/désaccordage (280) correspondant respectivement auxdits réseaux de bobines (290). Le système de diagnostic comprend un premier circuit d'échantillonnage de courant (131) et un processeur (132). Le premier circuit d'échantillonnage de courant (131) est conçu pour obtenir un premier courant. Le processeur (132) est configuré pour diagnostiquer le système d'accordage/désaccordage en fonction du premier courant.
