Abstract

Un système selon un mode de réalisation de la présente invention concerne plus simplement une infrastructure de collecte d'informations opérationnelles relatives à des machines. Le système selon le mode de réalisation comprend un premier dispositif de communication fixé à un véhicule tel qu'un équipement agricole, un deuxième dispositif de communication pouvant être transporté de façon portable par un conducteur du véhicule et capable de communiquer avec le premier dispositif de communication ainsi qu'un troisième dispositif de communication capable de communiquer avec le deuxième dispositif de communication. Le système fonctionne comme un système de collecte d'informations opérationnelles du véhicule prenant par exemple la forme d'un équipement agricole, il acquiert les informations opérationnelles du véhicule via le premier dispositif de communication en utilisant le deuxième dispositif de communication transporté de façon portable par le conducteur du véhicule et transmet les informations opérationnelles du véhicule acquises à l'aide du deuxième dispositif de communication via le troisième dispositif de communication installé dans une résidence ou un hôtel, etc. à un dispositif de serveur gérant les informations opérationnelles du véhicule.
