Title (EN) PROCESS FOR TRANSFERRING INFORMATION AND SYSTEM FOR CARRYING OUT THE PROCESS
(FR) PROCEDE DE TRANSFERT D"INFORMATIONS ET SYSTEME DE MISE EN OEUVRE DU PROCEDE
Abstract: front page image
(EN)Process for transferring power and information on one or more common lines (4, F1, F2) obviating known drawbacks, such as elimination known per se of one or more complete half waves of an alternating supply current leads to a noticeable reduction in the power transferred, and that in this known process no information can be transmitted in a direction towards the supply current. The process is characterized in that a first type of information where the rate of transmission depends upon the frequency of the current supply, is transmitted by essentially cutting off the current connection (e.g. by means of the converter 9, fig. 1) to the supply source in periods (T4-T5, fig. 2A) which constitute a fraction of a half wave interval, and that a second type of information which is not dependent upon the frequency of the current supply, is transmitted during the periods in which the current connection to the supply source is essentially cut off.
(FR)Procede de transfert d"energie electrique et d"information sur une ou plusieurs lignes communes (4, F1, F2) evitant des inconvenients connus, tels que l"elimination connue en soi d"une ou plusieurs demi-ondes completes d"un courant d"alimentation alternatif, donnant une reduction sensible de la puissance transferee, ce procede connu ne permettant pas de transmettre des informations en direction du courant d"alimentation. Le procede se caracterise en ce qu"un premier type d"informations ou la vitesse de transmission depend de la frequence du courant d"alimentation, est transmis en coupant la connexion du courant (p.ex. au moyen du convertisseur (9), fig. 1) vers la source d"alimentation selon des periodes (T4-T5, fig. 2A) qui constituent une fraction d"un intervalle de demi-onde, et en ce qu"un second type d"information qui ne depend pas de la frequence du courant d"alimentation, est transmis pendant les periodes dans lesquelles la connexion du courant vers la source d"alimentation est coupee.
