Abstract

L'invention concerne un appareillage décrit, consistant en un ou davantage d'appareils (4a-l) de surveillance de machine qui se fixent à une ou davantage de machines en vue de détecter une caractéristique physique de la machine, telle sa vibration ou sa température, et de produire des transmissions sans fil correspondant à la caractéristique détectée, et une station (6) de commande recevant les transmissions provenant des appareils (4a-l) de surveillance des machines, et traitant ces informations afin de donner une indication sur l'état de la machine. L'appareil de surveillance de machine incorpore un émetteur (446) sans fil destiné à transmettre les données de détection, et la station (6) de commande incorpore un récepteur (618) sans fil destiné à recevoir les données de détection. Dans le mode de réalisation préféré de cette invention, les appareils (4a-l) de surveillance de machine ne fonctionnent pas en continu, mais se mettent en marche seulement à des temps pré-programmés, selon des instructions de mise en marche produites par un circuit (424) temporiseur situé à l'intérieur de chaque appareil. Chaque appareil de surveillance de machine comprend un micro-ordinateur (418) permettant d'analyser les données de détection, et une mémoire (422) destinée à stocker les données de détection analysées. Des répéteurs (8a-d) facilitant les communications entre la station de commande et les appareils de surveillance de machine sont prévus selon les besoins.
