Abstract

La présente invention a trait à un système de surveillance pour des molécules de gaz et des molécules dans l'eau via un réseau utilisant l'Internet et une base de données dans laquelle des structures physiques et des propriétés chimiques de molécules à être détectées sont construites au moyen de la technologie d'identification de molécules. Des dispositifs capteurs sont installés à des points de surveillance en vue de la surveillance de la situation où du gaz se produit. Des données de mesures prises par les dispositifs capteurs sont transmises à un serveur central via un réseau. Le serveur central comporte une base de données pour la détermination de l'espèce de molécules et la collation des données de mesures transmises avec les données dans la base de données pour la détermination de l'espèce de molécules du gaz. Si l'espèce de molécule est considérée comme étant nuisible et identifiée, le dispositif d'élimination de gaz au point de surveillance est mis en opération.
