Abstract[English]
In an aspect, there is provided a method of monitoring operations of a pulse width modulation (PWM) valve and nozzle assembly for a fluid application of an agricultural implement. The method includes applying a current during one or more time periods to open the PWM valve during a fluid application of the agricultural implement, monitoring pressure of a pressure sensor of the PWM valve and nozzle assembly during the one or more time periods, determining whether pressure spikes of the pressure of the pressure sensor correspond to a commanded frequency of the PWM valve during the one or more time periods, and determining whether the PWM valve is stuck fully open, fully closed, or partially open when the pressure spikes of the pressure of the pressure sensor do not correspond to the commanded frequency of the PWM valve during the one or more time periods.[French]
Selon un aspect, l'invention concerne un procédé de surveillance du fonctionnement d'un ensemble soupape et buse de modulation de largeur d'impulsion (MLI) pour l'application d'un fluide d'un outil agricole. Le procédé consiste à appliquer un courant pendant une ou plusieurs périodes de temps pour ouvrir la soupape MLI pendant l'application d'un fluide de l'outil agricole, à surveiller la pression d'un capteur de pression de l'ensemble soupape et buse MLI pendant la ou les périodes de temps, à déterminer si des pics de pression de la pression du capteur de pression correspondent à une fréquence commandée de la soupape MLI pendant la ou les périodes de temps, et à déterminer si la soupape MLI est bloquée en ouverture complète, en fermeture complète ou en ouverture partielle lorsque les pics de pression de la pression du capteur de pression ne correspondent pas à la fréquence commandée de la soupape MLI pendant la ou les périodes de temps.
