Abstract[English]
The present invention relates to a method for determining the concentration of a chemical compound of a fluid by means of an optical measurement system for measuring a light intensity spectrum, such that: (i) by means of a learning base comprising a plurality of learning light intensity spectra measured for a plurality of learning fluids each having a predetermined concentration, a model is constructed in order to determine the concentration of at least one chemical compound in a fluid by training a one-dimensional convolutional neural network on the learning base, the network being such that the number of convolutional filters per layer decreases with the position of the layer in the network; (ii): by means of the optical measurement system, at least one light intensity spectrum of the fluid is measured; (iii) the constructed model is applied to the measured light intensity spectrum, and the concentration of the chemical compound in the fluid is determined.[French]
La présente invention concerne un procédé pour déterminer la concentration d'un composé chimique d'un fluide, au moyen d'un système de mesure optique pour mesurer un spectre d'intensité lumineuse, tel que : (i) au moyen d'une base d'apprentissage comprenant une pluralité de spectres d'intensité lumineuse d'apprentissage mesurés pour une pluralité de fluides d'apprentissage dont la concentration est prédéterminée, on construit un modèle pour déterminer la concentration d'au moins un composé chimique d'un fluide en entraînant un réseau de neurones convolutif unidimensionnel sur la base d'apprentissage, le réseau étant tel que le nombre de filtres convolutifs par couche décroit avec la position de la couche dans le réseau; (ii) : au moyen du système de mesure optique, on mesure au moins un spectre d'intensité lumineuse du fluide; (iii) on applique le modèle construit au spectre d'intensité lumineuse mesuré, et on détermine la concentration en le composé chimique du fluide.
