Abstract
(EN)
A ventilator proportional valve (50) flow control method, device, and computer device, comprising reading a ventilator system operating parameter (S200); inputting the ventilator system operating parameter into a preset neural network model generated by training on the basis of historical ventilator system operating parameters (S400); acquiring a current signal output by the preset trained neural network model according to the ventilator system operating parameter (S600); and inputting the current signal to a proportional valve (50) in the ventilator to control the flow of the proportional valve (S800). By inputting current ventilator system operating parameters into a preset neural network model generated by training on the basis of historical ventilator system operating parameters, an appropriate current signal can be obtained, and the flow of the ventilator proportional valve (50) can be effectively controlled based on the appropriate current signal, such that the proportional valve (50) is capable of adapting to the impact of changes in external interference factors during the flow control process.

L'invention concerne un procédé, un dispositif et un dispositif informatique de commande de débit de soupape proportionnelle de ventilateur (50), comprenant la lecture d'un paramètre de fonctionnement de système de ventilateur (S200) ; l'application du paramètre de fonctionnement de système de ventilateur dans un modèle prédéfini de réseau neuronal généré par apprentissage en fonction de paramètres historiques de fonctionnement de système de ventilateur (S400) ; l'acquisition d'un signal de courant émis par le modèle prédéfini de réseau neuronal instruit selon le paramètre de fonctionnement du système de ventilateur (S600) ; et l'application du signal de courant dans une soupape proportionnelle (50) dans le ventilateur pour commander le débit de la soupape proportionnelle (S800). En appliquant des paramètres actuels de fonctionnement de système de ventilateur dans un modèle prédéfini de réseau neuronal généré par apprentissage en fonction de paramètres historiques de fonctionnement de système de ventilateur, on peut obtenir un signal de courant approprié et le débit de la soupape proportionnelle de ventilateur (50) peut être efficacement commandé en fonction du signal approprié de courant, afin que la soupape proportionnelle (50) soit en mesure de s'adapter à l'impact de variations de facteurs externes d'interférence pendant le processus de commande de débit.
