Abstract

L'invention concerne un montage pour réaliser la commande sûre d'unités d'affichage. Dans ce montage qui comporte une unité de traitement des données DVE délivrant des caractères à des unités d'affichage AE1... AEn par l'intermédiaire de mémoires ZSP1, ZSP2 mémorisant les signaux de code, et par l'intermédiaire de décodeurs ZDC1, ZDC2, les unités d'affichage AE1... AEn sont reliées successivement à ces décodeurs à une basse fréquence de l'ordre de 1 Hz. Application notamment aux systèmes d'affichage des chiffres dans des postes à essence de stations service.The invention relates to an arrangement for achieving safe control of display units. In this assembly which comprises a data processing unit DVE delivering characters to display units AE1 ... AEn via memories ZSP1, ZSP2 storing the code signals, and via decoders ZDC1, ZDC2, the display units AE1 ... AEn are successively connected to these decoders at a low frequency of the order of 1 Hz. Application in particular to systems for displaying numbers in petrol stations at service stations.
