Title
(EN) SELF-TEST METHOD FOR A RANGING SENSOR-ARRANGEMENT OF A WORK MACHINE
(FR) PROCÉDÉ D'AUTO-TEST POUR UN AGENCEMENT DE CAPTEUR DE MESURE DE DISTANCE D'UNE MACHINE DE TRAVAIL
Abstract
(EN) The present disclosure relates to a computer-implemented method and arrangement for diagnosing a level of dust impact on one or more range detection sensors comprised in a work machine. In particular, the disclosure relates to a method and a tramming assist arrangement for diagnosing a level of dust impact on one or more range detection sensors based on a plurality of range readings. The method comprises obtaining a set of range readings from respective range detection sensors; each range reading comprising measured distances. The method further comprises attributing range comprising measured distances within configurable intervals to respective groups for each range detection sensor based on the measured distances, and determining a level of dust impact on sensor visibility for the one or more range detection sensors based on the range readings attributed to the respective groups.
(FR) La présente invention concerne un procédé et un agencement mis en œuvre par ordinateur permettant de diagnostiquer un niveau d'impact de poussière sur un ou plusieurs capteurs de détection de distance compris dans une machine de travail. En particulier, l'invention concerne un procédé et un dispositif d'assistance au traçage pour diagnostiquer un niveau d'impact de la poussière sur un ou plusieurs capteurs de détection de distance sur la base d'une pluralité de lectures de distance. Le procédé comprend l'obtention d'un ensemble de lectures de distance à partir de capteurs de détection de distance respectifs ; chaque lecture de distance comprenant des distances mesurées. Le procédé comprend en outre l'attribution d'une distance comprenant des distances mesurées dans des intervalles configurables à des groupes respectifs pour chaque capteur de détection de distance sur la base des distances mesurées, et la détermination d'un niveau d'impact de la poussière sur la visibilité du capteur pour le ou les capteurs de détection de distance sur la base des lectures de distance attribuées aux groupes respectifs.
