Abstract

La présente invention porte sur un procédé et un système de surveillance d'un environnement d'atelier sur la base de l'internet des objets. Le procédé consiste : à recevoir des informations de paramètres environnementaux à l'intérieur de l'atelier ; sur la base d'informations de dispositif, à demander des informations de numéro d'atelier préliées ; sur la base des informations de numéro d'atelier, à demander des informations de type d'atelier associées et des informations de seuil de paramètres d'environnement correspondant au type d'atelier ; à comparer les informations de paramètres environnementaux aux informations de seuil de paramètres environnementaux et, sur la base des résultats de comparaison, lorsqu'une condition d'avertissement est satisfaite, à émettre différents niveaux de notifications d'avertissement. L'invention porte également sur un système, le système comprenant : un module récepteur et un module de traitement. En réglant différents seuils de paramètres pour différents ateliers sur la base du type d'atelier, la présente invention acquiert des informations d'atelier liées sur la base d'informations de dispositif dans les informations de paramètres environnementaux téléversées par un dispositif détecteur, puis acquiert le type d'atelier, et acquiert le seuil de paramètres correspondant audit type d'atelier, contrôlant ainsi avec précision l'environnement de chaque atelier et accroissant l'efficacité de la production industrielle.
