Interface device for a telematics station

The invention relates to an interface device for a telematics station. It is a microcomputer (Bus on which there are connected a microprocessor, backed-up volatile random-access memory, non-volatile random-access memory, read-only memory) making it possible to resolve: - the technical problems of compatibility between the various elements of a telematics network (host computer, transmission network, workstations, application); - the ergonomic problems linked to the complexity of the connection procedures and to the existence of computer background noise. It also makes it possible to carry out chaining of data exchanges between workstations and computer or between two workstations. It provides transcoding of messages, flow control and routing of data between the various elements of the workstation. L'INVENTION CONCERNE UN DISPOSITIF D'INTERFACE POUR POSTE TELEMATIQUE. C'EST UN MICRO-ORDINATEUR (BUS SUR LEQUEL SONT CONNECTES UN MICROPROCESSEUR, DE LA MEMOIRE VIVE VOLATILE, DE LA MEMOIRE VIVE NON VOLATILE SAUVEGARDES, DE LA MEMOIRE MORTE) PERMETTANT DE RESOUDRE:-LES PROBLEMES TECHNIQUES DE COMPATIBILITE ENTRE LES DIFFERENTS ELEMENTS D'UN RESEAU TELEMATIQUE (ORDINATEUR HOTE, RESEAU DE TRANSMISSION, POSTES DE TRAVAIL, APPLICATION);-LES PROBLEMES ERGONOMIQUES LIES A LA COMPLEXITE DES PROCEDURES DE CONNEXION ET A L'EXISTENCE D'UN BRUIT DE FOND INFORMATIQUE.IL PERMET EGALEMENT D'ASSURER DES ENCHAINEMENTS D'ECHANGES D'INFORMATIONS ENTRE POSTES DE TRAVAIL ET ORDINATEUR OU ENTRE DEUX POSTES DE TRAVAIL. IL ASSURE LE TRANSCODAGE DE MESSAGES, LE CONTROLE DE FLUX ET L'AIGUILLAGE DES INFORMATIONS ENTRE LES DIFFERENTS ELEMENTS DU POSTE DE TRAVAIL.
