Abstract

La présente invention améliore la sécurité d'un compresseur d'air. Le compresseur d'air selon l'invention possède un moteur (16) destiné à être entraîné par l'alimentation électrique provenant d'une source d'alimentation, une unité de production d'air comprimé pour produire de l'air comprimé lorsque le moteur (16) est entraîné, un réservoir pour stocker l'air comprimé produit par l'unité de production d'air comprimé, et un panneau d'exploitation (37) pour donner des instructions d'activation/arrêt du moteur (16) et pour commuter un mode d'entraînement du moteur (16). De plus, le compresseur d'air possède une carte de commande (32) pour commander l'entraînement du moteur (16) conformément à un signal de fonctionnement provenant du panneau d'exploitation (37) et pour commander l'opération de compression d'air par l'unité de production d'air comprimé, une unité de lecture (39a) pour lire des informations d'authentification, et une carte de commande d'informations (39) pour exécuter une authentification sur base des informations d'authentification lues par l'unité de lecture (39a), et le compresseur d'air est structuré de telle sorte que la carte de commande d'informations (39) et le panneau d'exploitation (37) sont disposés séparément l'un de l'autre.
