Abstract

La présente invention concerne la commande de l'isolement d'une machine. Un ordinateur reçoit un identifiant de machine de la machine de la part d'un opérateur et détermine, d'après l'identifiant de machine, une adresse de communication associée à la machine. L'ordinateur envoie alors une demande d'isolement de la machine à l'adresse de communication, reçoit une confirmation d'isolement de la machine et génère une notification adressée à l'opérateur pour indiquer que la machine est isolée. Ce procédé est particulièrement avantageux lors du ravitaillement en carburant d'un engin minier ou de construction, comme une pelle, car l'opérateur peut demander l'isolement et recevoir une confirmation sans s'approcher physiquement de la machine. Par conséquent, l'opérateur peut rester dans un environnement sûr, comme la cabine d'un camion de carburant jusqu'à ce que la machine à ravitailler soit isolée et qu'il soit possible de s'approcher de la machine en toute sécurité. Le procédé accroît la sécurité et réduit les blessures et les accidents mortels.
