Abstract
Un système est prévu pour maintenir un débit d'air adapté dans un écoulement d'air d'un semoir pneumatique. Un ventilateur produit un écoulement d'air qui permet de transporter des matériaux agricoles avant de les répartir sur une largeur d'un dispositif d'ensemencement. Un réservoir contient un matériau agricole granulaire et un dispositif de dosage distribue le matériau dans l'écoulement d'air. Le système est calibré de telle sorte qu'un poids connu de matériau est distribué à chaque tour du dispositif de dosage où l'on voit que la vitesse de rotation du dispositif de dosage multipliée par le poids connu par tour donne un taux connu par minute de matériau agricole distribué dans l'écoulement d'air. Un microprocesseur est programmé pour déduire une vitesse de ventilateur adaptée au taux par minute de matériau agricole distribué et pour envoyer un signal à une commande de ventilateur pour régler la vitesse du ventilateur afin qu'elle corresponde à la vitesse de ventilateur adaptée.
