Abstract
In a rail system with a rail and mobile parts movable along the rail, e.g., rail vehicles, a profiled part is arranged on the rail and includes a cavity, which, e.g., terminates at an opening into the environment. Regions of a mobile part, e.g., regions of each mobile part, at least partially project into the cavity, and at least one transmitter and receiver are situated in the respective region.
Claims25
A rail system, comprising:
- a rail including a profiled part arranged on the rail and having a first cavity and a second cavity that extend in parallel to each other and that terminate at an opening into the environment;
- and
- mobile parts adapted to move along the rail;
- wherein regions of at least one of the mobile parts at least partially project into the first cavity and into the second cavity, a first one of the regions including a first transmitter and a first receiver arranged in the first cavity, a second one of the regions including a second transmitter and a second receiver arranged in the second cavity, and a stationary transmitter and a stationary receiver are arranged at at least one of the regions of the mobile part that at least partially projects into the first cavity and/or the second cavity.

A rail system, comprising:
- a rail including a profiled part arranged on the rail and having a cavity that terminates at an opening into the environment;
- and
- mobile parts adapted to move along the rail and including an antenna projecting at least partially into the cavity to couple and/or decouple electromagnetic waves;
- wherein the profiled part is arranged as a slotted waveguide and/or a hollow waveguide and is adapted to conduct electromagnetic waves inside the cavity;
- and
- wherein a transmitter and a receiver are arranged in a region of at least one of the mobile parts outside the cavity and in such close proximity to the opening that light is radiatable into the cavity with the aid of the transmitter, and light conducted through the cavity is detectable with the aid of the receiver such that the mobile part exchanges data with the aid of the electromagnetic waves and also with the aid of light.
