Title:
TELPHER LINE WITH CONTACTLESS ENERGY AND DATA TRANSMISSION
Document Type and Number:
WIPO Patent Application WO2003026915
Kind Code:
A8
Abstract:
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.
