Definitions

  • an object detection unit that detects a predetermined object existing within a predetermined range around a work machine, and an alarm unit that issues a sound alarm when the object detection unit detects the object.
  • the alarm unit stops the alarm by the sound and outputs the sound by the sound when a predetermined condition is satisfied.
  • a perimeter monitoring system for a work machine is disclosed, which issues a warning by light after the warning is stopped.

Abstract

L'invention concerne une excavatrice hydraulique qui utilise des images capturées par de multiples caméras de surveillance pour générer une image plane de vue en vol d'oiseau, génère une image d'icône schématisée qui représente la carrosserie de véhicule en vue plane, effectue un traitement de synthèse pour afficher une image de vue plane autour de l'image d'icône et, dans la zone où la vue frontale de la caméra côté gauche est bloquée par la cabine de l'opérateur, combine une icône différente des images capturées par les multiples caméras de surveillance, générant une image composite. Il est ainsi possible pour l'opérateur de surveiller la périphérie sans s'inquiéter.
