Abstract
(EN)
Disclosed are an apparatus and method for controlling a remote-controlled excavator for preventing overload. The apparatus for controlling a remote-controlled excavator according to an embodiment of the present invention comprises: inertial sensors provided in the excavator; a communication unit for receiving a remote control signal from a remote control apparatus; and a control unit for driving the excavator in response to the remote control signal, wherein the control unit stops driving the excavator when a difference between an expected posture of the excavator estimated on the basis of the remote control signal and an actual posture of the excavator measured by using the inertial sensors exceeds an allowable value.
(FR)
La présente invention concerne un appareil et un procédé destinés à commander une excavatrice télécommandée servant à empêcher une surcharge. L'appareil de commande d'une excavatrice télécommandé selon un mode de réalisation de la présente invention consiste : en des capteurs inertiels disposés dans l'excavatrice; en une unité de communication destinée à recevoir un signal de télécommande à partir d'un appareil de télécommande; et en une unité de commande destinée à conduire l'excavatrice en réponse au signal de télécommande, l'unité de commande arrêtant la conduite de l'excavatrice lorsqu'une différence entre une posture attendue de l'excavatrice estimée sur la base du signal de télécommande et une posture réelle de l'excavatrice mesurée à l'aide des capteurs inertiels dépasse une valeur admissible.
