Title (EN) ELECTRICAL SUPERVISORY CONTROL AND DATA ACQUISITION SYSTEM
(FR) SYSTEME ELECTRIQUE DE CONTROLE ET DE SAISIE DE DONNEES
Abstract: front page image
(EN)Electrical control system which comprises: a master station (2) and a plurality of receiver stations (4) connected thereto by a bus (6), the master station including generating means (20, 22) for generating control signals (16) which are applied to said bus and to which said receiver stations are responsive, the control signals comprising a repetitive series of signal frames, each frame including a reset pulse (18) and a plurality of other pulses, the master station including control means (14) which causes selectable alteration of a characteristic of said other pulses, and wherein each of said receiver stations is addressed following receipt of a respective predetermined number of said other pulses, said receivers being responsive to said selectable characteristic of the other pulses whereby control instructions are transmitted to addressed receiver stations in accordance with operation of said control means, wherein data and address information are contained within the same other pulse. The system may further include circuitry (68, 69, 70) which permits the receiver being addressed to transmit information on its status to the master station. The system would have wide applications, for instance, in nurse paging systems in hospitals.
(FR)Systeme electrique de controle comprenant: une station principale (2) et une pluralite de stations peripheriques (4) connectees a la station principale par un bus (6), la station principale des moyens de production de signaux (20, 22) servant a produire des signaux de commande (16) qui sont appliques aux bus, auxquels signaux les stations peripheriques sont sensibles, les signaux de commande comprenant une serie repetitive de sequences de signaux, chaque sequence comprenant une impulsion de remise a zero (18) et une pluralite d"autres impulsions, la station principale comprenant des moyens de commande (14) provoquant une alteration pouvant etre selectionnee des caracteristiques de ces autres impulsions, chaque station peripherique etant adressee apres reception d"un nombre predetermine respectif des autres impulsions, les stations peripheriques etant sensibles aux caracteristiques pouvant etre selectionnees des autres impulsions permettant la transmission d"instructions de commande aux stations peripheriques adressees conformement au fonctionnement dudit moyen de commande, les donnees et l"information d"adresse etant contenues dans la meme autre impulsion. Le systeme peut en outre comprendre des circuits (68, 69, 70) permettant a la station peripherique etant adressee de transmettre une information concernant son propre etat a la station principale. Le systeme peut s"appliquer, par exemple, a des systemes d"appel d"infirmieres dans des hopitaux.
