Title (EN) DIAGNOSTIC DEVICE FOR A PROCESS CONTROL SYSTEM
(FR) DISPOSITIF DE DIAGNOSTIC POUR SYSTEME DE COMMANDE DE PROCESSUS
Abstract: front page image
(EN)The diagnostic device (10) comprises a receiving means (100) for receiving process variable values (x(t)) of a process variable of a process medium of a process, a measurement processing means (300) for extracting and recording measurement statistics data from such process variable values, which are measured during a measuring phase (300), a training processing means for extracting and recording training statistics data from such process variable values, which are measured during a training phase, and a comparison means (400) for comparing the measurement statistics data with training statistics data recorded before the measurement statistics data. Preferably, the training statistics data include a training empirical statistical distribution, which can be a distribution of a function of process variable values, which are measured during a training phase, or a distribution of a function of coefficients Xt(k), which are coefficients of a function of a transform of process variable values (x(t)), which are measured during a training phase.
(FR)L'invention porte sur un dispositif de diagnostic (10) qui comprend: des moyens de réception (100) destinés à recevoir des valeurs de variable de processus (x(t)) d'une variable de processus d'un support de processus d'un processus; des moyens de traitement de mesure (300) destinés à extraire et enregistrer des données statistiques de mesure à partir desdites valeurs de variable de processus, qui sont mesurées au cours d'une phase de mesure (300); des moyens de traitement d'entraînement destinés à extraire et enregistrer des données statistiques de mesure à partir desdites valeurs de variable de processus, qui sont mesurées au cours d'une pha
