The invention relates to a telpher line with contactless energy transmission between a supply line (4) which is arranged at a distance along a running rail (1) for mobile transport units (12) and an inductive current collector which is situated on the transport unit. In order to transmit data in a contactless manner between a central station (18) and the transport units, a data transmission loop (7) is arranged at a defined distance along the supply line in such a way that the parallel conductors of said loop are precisely situated in a field line of the supply line. Said data transmission loop is galvanically connected to the central station by means of a transmission station (10). For inductive coupling to the transport units, a communication module (6) comprising emission and reception coils on ferrite cores is arranged on said transport units, said module being able to receive all information exchanged on the data transmission loop. The inductive transmission is carried out in the form of sinusoidal signal sequences used as digital signals in two different fixed frequencies in the mean frequency range.

Transporteur aérien électrique avec transmission sans contact d'énergie entre une ligne d'alimentation (4) placée le long d'un rail de roulement (1) pour unités de transport mobiles (12) à un certain écart dudit rail et une prise de courant inductive située sur l'unité de transport, dans lequel une boucle de transmission de données (7) est disposée selon un écart défini le long de la ligne d'alimentation, en vue de la transmission de données sans contact entre une station centrale (18) et les unités de transport, de manière telle que les conducteurs parallèles de ladite boucle se trouvent précisément dans une ligne de champ de la ligne d'alimentation. La boucle de transmission de données est connectée de manière galvanique avec la station centrale via une station de transmission (10). En vue du couplage inductif avec les unités de transport, un module de communication (6) possédant des bobines d'émission et de réception à tore en ferrite est monté sur ces dernières, ledit module pouvant recevoir lui aussi toutes les informations échangées sur la boucle de transmission de données. La transmission inductive se produit sous forme de suite de signaux sinusoïdaux servant de signaux numériques dans deux fréquences fixes distinctes de la plage des fréquences moyennes.
