Abstract

L'invention concerne : un terminal de service qui, en tant que terminal qui utilise un réseau de communication à large bande de faible puissance pour fournir divers services à faible puissance au conducteur d'un véhicule, peut être connecté à une boîte noire préinstallée dans le véhicule ; et un procédé de connexion de la boîte noire. Lorsque le terminal de service de la présente invention est utilisé, non seulement un récepteur GPS, mais également une configuration pour traiter un service par l'intermédiaire d'un réseau à large bande de faible puissance peut être connectée en même temps à une boîte noire conventionnelle qui ne fournit qu'un seul port pour connecter le récepteur GPS. En conséquence, le terminal de service peut non seulement (1) fournir des données GPS qui ont été reçues en provenance du récepteur GPS, mais peut également (2) afficher des données requises pour un service LPWAN sur une unité d'affichage de la boîte noire et recevoir une commande de contrôle utilisateur par l'intermédiaire d'une unité d'entrée de la boîte noire, même lorsqu'elle n'est pas équipée d'interfaces utilisateur, tel qu'une unité d'affichage et une unité d'entrée, pour des raisons telles qu'une opération à faible puissance.
