Abstract

Selon la présente invention, un système de gestion de flotte commande à une unité de travail mobile la position depuis laquelle elle devra transmettre au centre de gestion de flotte un compte rendu contenant la position de l'unité de travail mobile. Le centre de gestion de flotte définit une zone d'intervention qu'il communique à l'unité de travail mobile via un réseau public de radiocommunications. L'unité de travail mobile utilise ce réseau public de radiocommunications pour rendre compte automatiquement dès que les conditions de compte rendu sont réunies. Ces conditions peuvent être simplement l'entrée ou la sortie de la zone d'intervention, ou des conditions supplémentaires liées à des relations entre positions. Le compte rendu par l'unité de travail mobile ne dépend ni de la position de l'unité de travail mobile par rapport à la station de base ni de la simple réalisation d'un événement particulier. Au contraire, le compte rendu est fonction de la position de l'unité de travail mobile par rapport à la zone d'intervention définie telle qu'elle a été transmise à l'unité de travail mobile via le système radio.
