Abstract

L'invention concerne un procédé et un système de traitement de données appliqués à l'Internet des objets, comprenant les étapes suivantes : lorsqu'il est identifié que l'emplacement d'un dispositif terminal compris dans des données de l'Internet des objets qui sont rapportées par n'importe quel dispositif terminal correspond à un emplacement d'intérêt pour une unité d'agrégation, un nœud d'acheminement obtient le type météorologique en temps réel correspondant à l'emplacement du dispositif terminal ; lorsqu'il est identifié que le type météorologique en temps réel correspondant à l'emplacement du dispositif terminal est cohérent par rapport au type météorologique qui est spécifié par l'unité d'agrégation, les données de l'Internet des objets qui ont été initiées par le dispositif terminal sont encapsulées dans un élément de données puis rapportées à une passerelle de filtrage ; la passerelle de filtrage détermine, à partir des éléments de données qui sont rapportés par divers nœuds d'acheminement, un élément de données comprenant le type de dispositif terminal qui est spécifié par l'unité d'agrégation et un identifiant de version de système d'exploitation de dispositif terminal spécifié en tant qu'élément de données à rapporter, et rapporte ces derniers à l'unité d'agrégation en vue d'une analyse et d'une décision. La charge de travail de l'unité d'agrégation peut être efficacement réduite, tout en améliorant la précision de l'unité d'agrégation en ce qui concerne l'obtention de données de dispositif terminal qui présentent un intérêt.
