Title
(EN) REMOTE OPERATION SYSTEM FOR WORK MACHINE
(FR) SYSTÈME DE MANŒUVRE À DISTANCE POUR MACHINE DE TRAVAIL
(JA) 作業機械の遠隔操作システム
Abstract
(EN) This remote operation system for a work machine comprises: a sensor data reception unit for receiving detection data of the orientation of a work device of the work machine operated by an operation signal from a remote location; a warning control unit for outputting a warning control signal if it is determined that the work device is approaching or has reached an end position of a movable range on the basis of the detection data; and a warning device provided in the remote location and for outputting a warning on the basis of the warning control signal from the warning control unit.
(FR) L'invention concerne un système de manœuvre à distance pour une machine de travail qui comprend : une unité de réception de données de capteur pour recevoir des données de détection de l'orientation d'un dispositif de travail de la machine de travail manœuvrée par un signal de manœuvre depuis un emplacement distant; une unité de commande d'avertissement pour émettre un signal de commande d'avertissement s'il est déterminé que le dispositif de travail s'approche ou a atteint une position finale d'une plage mobile sur la base des données de détection; et un dispositif d'avertissement situé dans l'emplacement distant et destiné à émettre un avertissement sur la base du signal de commande d'avertissement provenant de l'unité de commande d'avertissement.
(JA) 作業機械の遠隔操作システムは、遠隔地からの操作信号により動作する作業機械が有する作業機の姿勢の検出データを受信するセンサデータ受信部と、検出データに基づいて、作業機が可動範囲の端部位置に接近している又は到達したと判定した場合、警報制御信号を出力する警報制御部と、遠隔地に設けられ、警報制御部からの警報制御信号に基づいて、警報を出力する警報装置と、を備える。
