Title
(EN) TRACK TRENCHER CONTROL SYSTEM AND PROCESS
(FR) SYSTEME ET PROCEDE DE COMMANDE D'UN EXCAVATEUR DE TRANCHEES A CHENILLES
Abstract
(EN)
A system and process for operating a track trencher excavation machine includes multiple mode propulsion and steering controls that perform a plurality of functions depending on a selection of one of a plurality of operational modes. A computer modifies the functions of the multiple mode propulsion and steering controls depending on a selected operational mode, and coordinates propulsion of the engine and track drives of a track trencher in response to signals produced by the propulsion and steering controls. A display communicates status, fault, and other information to an operator during track trencher operation. Operator presence within a control area of the track trencher is monitored. Excavation and track trencher operation is interrupted upon detection of an operator leaving the control area. Automatic shutdown of the engine preferably occurs upon detection of one of a plurality of severe anomalous operating conditions.
(FR)
Un système et un procédé de manoeuvre d'un excavateur de tranchées à chenilles font appel à des commandes de propulsion et de direction multimodes remplissant une pluralité de fonctions, selon la sélection d'un des multiples modes de fonctionnement. Un ordinateur modifie les fonctions des commandes de propulsion et de direction multimodes selon le mode de fonctionnement sélectionné et coordonne la propulsion du moteur et les entraînements d'un excavateur de tranchées en réponse à des signaux produits par les commandes de propulsion et de direction. Un écran permet à l'opérateur de prendre connaissance de l'état, des erreurs et d'autres informations pendant le fonctionnement de l'excavateur de tranchées. La présence de l'opérateur dans une zone de commande de l'excavateur de tranchées à chenilles est contrôlée. L'excavation et le fonctionnement de l'excavateur de tranchées sont interrompus lorsque le système détecte que l'opérateur quitte la zone de commande. Un arrêt automatique du moteur de préférence se produit lorsque l'une des conditions de fonctionnement gravement anormales possibles est détectée.
