Abstract

L'invention concerne un procédé de gestion de données d'entrepôts multiples fondée sur une chaîne de blocs, et un dispositif associé, permettant de gérer correctement et efficacement des matériaux dans des entrepôts multiples, d'améliorer l'efficacité de gestion des matériaux dans les entrepôts et d'améliorer la fiabilité des données des entrepôts. Le procédé comprend les étapes suivantes consistant : lorsque des données d'inventaire local d'un nœud d'entrepôt ayant fait l'objet d'un accès à la chaîne de blocs changent, à mettre à jour des données d'inventaire local d'un nœud d'entrepôt correspondant, le nœud d'entrepôt ayant fait l'objet d'un accès à la chaîne de blocs comprenant au moins deux nœuds ; à écrire les données d'inventaire local mises à jour dans le bloc et à les synchroniser dans la chaîne de blocs ; et à extraire de la chaîne de blocs, par le nœud d'entrepôt ayant fait l'objet d'un accès à la chaîne de blocs, les dernières données d'inventaire local de chaque nœud d'entrepôt, ce qui lui permet de compter les données d'inventaire du même type de matériaux dans chaque nœud d'entrepôt.
