Abstract
Ce système comprend : un dispositif de commande embarqué ; un dispositif de commande à distance ; et une machine de communication. Le dispositif de commande embarqué est monté sur un engin de chantier et commande l'engin de chantier. Le dispositif de commande à distance communique avec le dispositif de commande embarqué. Le dispositif de commande à distance transmet, à l'engin de chantier, un signal d'instruction de démarrage pour démarrer l'engin de chantier. La machine de communication est disposée sur un corps séparé du dispositif de commande à distance. La machine de communication communique avec le dispositif de commande embarqué. La machine de communication peut être actionnée de façon à faire commuter l'engin de chantier d'un état de démarrage interdit à un état de démarrage autorisé. Le dispositif de commande embarqué fait commuter l'engin de chantier de l'état de démarrage interdit à l'état démarrage autorisé en réponse à une opération sur la machine de communication. Lorsque l'engin de chantier est dans l'état de démarrage interdit, le dispositif de commande embarqué empêche l'engin de chantier de démarrer même si le signal d'instruction de démarrage est reçu en provenance du dispositif de commande à distance. Lorsque l'engin de chantier est dans l'état de démarrage autorisé, le dispositif de commande embarqué amène l'engin de chantier à démarrer si le signal d'instruction de démarrage est reçu en provenance du dispositif de commande à distance.
