Abstract

Le problème à résoudre est de pourvoir, par utilisation d'une structure relativement simple, à un système de communication de données qui puisse réduire le volume et les frais de communication entre un système de télésurveillance et un contrôleur de boutique. A cet effet, l'invention porte sur un système de communication de données qui comprend : un contrôleur de boutique (1) qui collecte des données provenant d'un dispositif connecté et stocke les données collectées ; et un système de télésurveillance (3) qui, en réponse à une requête de référence de données provenant d'un client utilisateur (4), collecte les données, qui ont été collectées par le contrôleur de boutique, par l'intermédiaire d'un réseau et stocke les données collectées et les fournit en outre au client utilisateur. Le système de télésurveillance comprend : un moyen pour collecter, en provenance du contrôleur de boutique, seulement les données ayant des conditions de collecte désignées par le client utilisateur ; un moyen pour attribuer un identificateur de gestion aux données collectées pour une association entre eux ; et un moyen pour enregistrer l'identificateur et les conditions de collecte désignées par l'utilisateur dans une base de données de manière à ce que l'identificateur soit associé aux conditions de collecte désignées par l'utilisateur dans un but de gestion.
