Abstract

La présente invention se rapporte au domaine technique de la navigation en intérieur. L'invention concerne un système de navigation cartographique pour une utilisation dans un grand bâtiment, apte à fournir une navigation en intérieur pour un utilisateur portant un terminal numérique. Le système de navigation comprend : un routeur de commande pour configurer un réseau sans fil; et de multiples points d'accès répartis dans des salles respectives dans un grand bâtiment. Le routeur de commande calcule des emplacements relatifs en fonction du retard dans un transfert de données entre le terminal numérique accédant au réseau sans fil de ce dernier et les points d'accès respectifs, et émet des informations d'emplacement au terminal numérique. Le terminal numérique est construit dans une partie de logiciel cartographique électronique. Le logiciel cartographique électronique affiche, en temps réel, des informations de navigation selon les informations d'emplacement. Le système de navigation cartographique pour une utilisation dans un grand bâtiment selon l'invention peut suivre automatiquement un emplacement d'un terminal numérique accédant à un réseau sans fil, et émettre des signaux pour fournir au terminal numérique des informations d'emplacement. Le logiciel cartographique électronique construit dans le terminal numérique utilise des informations d'emplacement pour fournir une navigation à un utilisateur, de telle sorte que l'utilisateur peut déterminer intuitivement son emplacement et trouver un emplacement cible.
