Title (EN) APPARATUS AND METHOD FOR MEASURING SUSPENSION AND CONTROLLING PROCESS OF SUSPENSION
(FR) APPAREIL ET PROCÉDÉ DE MESURE DE SUSPENSION ET DE COMMANDE DE PROCESSUS DE SUSPENSION
Abstract:
(EN) An apparatus for measuring suspension comprises an image capturing device (100) for capturing at least one measurement image (200) of the suspension (102), the at least one measurement image presenting at least one solid particle (202); an information processing unit (112) which receives the at least one measurement image (200) and determines a state of attachment of the solid particles (202) of the suspension (102) to each other on the basis of pattern recognition applied to the at least one measurement image (200). The information processing unit (112) determines, on the basis of the state of the attachment of the solid particles (202) of the suspension (102), suspension data associated with at least one of the following: at least one process control chemical, at least one fiber property, at least one fines property, a relation between solid particles of different sizes, formation, and water content.
(FR) L'invention concerne un appareil de mesure de suspension comportant un dispositif de capture d'image (100) servant à capturer au moins une image de mesure (200) de la suspension (102), ladite au moins une image de mesure présentant au moins une particule solide (202) ; une unité de traitement d'informations (112) qui reçoit ladite au moins une image de mesure (200) et qui détermine un état de fixation des particules solides (202) de la suspension (102) les unes par rapport aux autres en fonction d'une reconnaissance de motif appliquée au niveau de ladite au moins une image de mesure (200). L'unité de traitement d'informations (112) détermine, en fonction de l'état de la fixation des particules solides (202) de la suspension (102), des données de suspension associées à au moins l'un des éléments suivants : au moins un produit chimique de commande de processus, au moins une propriété se rapportant aux fibres, au moins une propriété se rapportant aux fines, une relation entre des particules solides de différentes tailles, formation et teneur en eau.
