Title (EN) RADIO FREQUENCY EMISSIONS SENSING SYSTEM AND METHOD FOR THE CHARACTERIZATION OF SYSTEM OPERATION
(FR) SYSTÈME DE DÉTECTION D'ÉMISSIONS DE RADIOFRÉQUENCES (RF) ET PROCÉDÉ DE CARACTÉRISATION DE FONCTIONNEMENT DU SYSTÈME
Abstract:
(EN) An RF emissions sensing system including RF sensors for transmitting/receiving RF signals to and from engine system emission control components, a control unit for collecting/processing information from the RF signals and controlling system outputs. The RF emissions sensing system includes a means and method for the characterization of the operating state and/or performance of the engine system including the use of time-based or historical RF information and system outputs, the application/monitoring of pertubations to the engine system, the comparison of system outputs to baseline/reference system outputs, the periodic activation of the engine system after shut-down, the monitoring of changes in the electric or temperature profiles of the engine system emission control components, and communication with external sources to improve the accuracy of the system outputs.
(FR) L'invention concerne un système de détection d'émissions RF comprenant des capteurs RF servant à émettre/recevoir des signaux RF vers et à partir des composants de commande d'émission de système de moteur, et une unité de commande servant à collecter/traiter des informations à partir des signaux RF et à commander des sorties de système. Le système de détection d'émissions RF comprend un moyen et un procédé de caractérisation de l'état de fonctionnement et/ou du rendement du système de moteur comprenant l'utilisation d'informations RF chronologiques ou historiques et de sorties de système, l'application des perturbations au système de moteur ou la surveillance de ces dernières, la comparaison de sorties de système à des sorties de système de ligne de base/de référence, l'activation périodique du système de moteur après arrêt, la surveillance de changements au niveau des profils électriques ou de température des composants de commande d'émission de système de moteur, et la communication avec des sources externes en vue d'améliorer la précision des sorties de système.
