(EN) SENSOR STATUS DETERMINATION BASED ON INDEPENDENT FUNDAMENTAL FREQUENCY MEASUREMENTS
(FR) DÉTERMINATION D'ÉTAT DE CAPTEUR SUR LA BASE DE MESURES DE FRÉQUENCES FONDAMENTALES INDÉPENDANTES
Abstract
(EN)
Methods, computing systems, and computer-readable media for detecting sensor malfunctioning status. The method includes receiving sensor measurements of a first type from a first type of sensor, deriving a first value for a metric from the sensor measurements of the first type, receiving sensor measurements of a second type from a second type of sensor, wherein the second measurements of the second type include a second value for the metric, comparing the first value to the second value, determining whether the first type of sensor or the second type of sensor is malfunctioning based on the comparing, and storing or outputting information indicating whether first type of sensor and the second type of sensor are malfunctioning.

L'invention concerne des procédés, des systèmes informatiques et des supports lisibles par ordinateur permettant de détecter un état de dysfonctionnement de capteur. Le procédé consiste à recevoir des mesures de capteur d'un premier type d'un premier type de capteur, à dériver une première valeur d'un paramètre à partir des mesures de capteur du premier type, à recevoir des mesures de capteur d'un second type d'un second type de capteur, les secondes mesures du second type comprenant une seconde valeur du paramètre, à comparer la première valeur à la seconde valeur, à déterminer si le premier type de capteur ou le second type de capteur présente un dysfonctionnement sur la base de la comparaison, et à mémoriser ou à délivrer des informations indiquant si le premier type de capteur et le second type de capteur présentent un dysfonctionnement.
