Abstract:
1. An electric telpher with non-contact power transmission between a feeder arranged at a spacing along a slide rail for a mobile transfer unit and an inductive current collector on the transfer unit as well as with non-contact data transmission between a central control station and a controller installed in the transfer unit, wherein a data transmission loop with terminating resistors at both ends and two parallel conductors that are located in one and the same field line of the feeder is arranged at a defined spacing along the feeder, in that said data transmission loop is direct-coupled with a central control station via a transmission station and inductively connected with the controller of the transfer unit via a communication module; said communication module comprising transmit and receive ferrite cores with a transmit or receive coil at a spacing to the data transmission loop for inductive transmission of digital signals in the form of sinusoidal sequences at two different frequencies in a medium frequency range.
