Abstract

La présente invention concerne un système de détection en ligne reposant sur des micro-ordinateurs à puce unique, comprenant de multiples capteurs agencés en fonction des besoins, et comprenant également un ordinateur hôte. Chaque capteur est connecté à un micro-ordinateur à puce unique. Les micro-ordinateurs à puce unique sont respectivement connectés en communication avec l'ordinateur hôte. L'invention concerne également un procédé de commande du système de détection en ligne reposant sur des micro-ordinateurs à puce unique. Le procédé consiste : premièrement, à effectuer un premier traitement analytique sur des résultats au moyen de micro-ordinateurs à puce unique, puis à effectuer un traitement par classification au moyen d'un ordinateur hôte, à effectuer une analyse intelligente sur les résultats de détection, et enfin, à afficher des résultats de détection spécifiques. Une personne n'a pas besoin d'effectuer de nouveau une analyse et peut directement prendre une mesure en fonction des résultats d'analyse, d'où une amélioration de l'efficacité de détection.
