Dans la présente divulgation, une pluralité de plateformes d'ouverture de porte mobiles et une pluralité de plateformes de fermeture de porte mobiles sont montées sur deux côtés de rails (13) et une pluralité de rideaux de lumière de mesure détectent un chariot à décharger et amènent les plateformes d'ouverture de porte ou les plateformes de fermeture de porte à entrer dans des positions de fonctionnement, de façon à amener une poignée d'ouverture de porte ou une poignée de fermeture de porte dudit chariot à tourner puis à amener une porte de fond à s'ouvrir ou à se fermer, de sorte que les exigences pour l'uniformité de types de véhicule d'une formation de véhicule soient réduites et qu'une porte de fond puisse être fermée pendant le mouvement bidirectionnel d'un chariot à décharger, ce qui permet d'améliorer l'applicabilité et l'efficacité de déchargement et de réduire le degré de participation manuelle.
