DETAILED DESCRIPTION

(7) As schematically illustrated in FIGS. 1 to 3, profiled part 5 has a cavity that is arranged to be open toward a first side.

(8) Profiled part 5 is situated in parallel with a system arranged as a rail system.

(9) Mobile parts 6, e.g., rail vehicles, which are movable on the rail are included in the system.

(10) The rail is, for example, produced as a metal profiled part.

(11) Profiled part 5 is, for example, made of plastic, and the cavity of profiled part 5 has mirrored side surfaces. The mirror coating is, for example, produced by a vapor metal deposition using chromium or a chromium-containing alloy, for example.

(12) Mobile parts 6 at least partially project into the cavity of profiled part 5 so that each mobile part 6 has a transmitter 4 and a receiver 3 on the front side in the rail direction. Each mobile part 6 similarly has a transmitter 4 and a receiver 3 also on the rear side.

(13) In the rail direction between transmitter 4 and receiver 3 on the front side and rear side, mobile part 6 has an absorber, which absorbs the radiation, e.g., light radiation, emitted by transmitters 4. The cavity upstream from absorber 7 in the rail direction and the cavity counter to the rail direction downstream from absorber 7 are thereby separated for the radiation to the effect that two separate data communication regions are able to be provided.

(14) This provides for mobile part 6 to exchange data with a further mobile part 6 at a distance in the rail direction, and also with a third mobile part 6 situated at a distance counter to the rail direction.

(15) Mobile parts 6 have, for example, an identical configuration.

(16) In addition, at least one transmitter 2 and one receiver 1 are immovably positioned on profiled part 5. It is therefore also possible to transmit data between a mobile part 6 and the stationary transmitter 2 and receiver 1.

(17) The cavity provided in profiled part 5 has a cross-sectional profile that is invariable in the rail direction because profiled part 5 can be produced as a continuous casting part.

(18) Although the cavity is open to the environment, the inner diameter of the cavity narrows more and more with decreasing distance from the outlet of the cavity to the environment. Thus, the cavity has a slot as an outlet and/or opening.

(19) An LED for the visible or infrared light range may, for example, be used as a transmitter 1, 3 and a correspondingly light-sensitive component such as a phototransistor or a photodiode may, for example, be used as a receiver 1, 3.

(20) Respective absorber 7 is situated on respective mobile part 6 such that the distance from profiled part 5 ideally is kept to a minimum and especially vanishes.

(21) To mount transmitter 4 and receiver 3, the particular region of mobile part 6 that projects into the cavity is provided with two leg regions, which are set apart from each other in the rail direction, e.g., in a U-shape.

(22) Thus, a transmitter 4 and a receiver 3 are situated on each of two the leg regions.

(23) Absorber 7 is situated on the mobile part between the two legs in the rail direction. Absorber 7 projects beyond the legs in all transverse directions in relation to the rail direction.

(24) When transmitters 2 and 4 are all operated at the same frequency, i.e., color, it is therefore possible to use only a half-duplex method in the data transmission.

(25) As illustrated in FIGS. 4 through 6, the profiled part is provided with two cavities that extend in parallel with each other. Each of these cavities is similar to the cavity of the exemplary embodiment illustrated in FIGS. 1 to 3.

(26) Mobile part 40 projects into both cavities. For each cavity, mobile part has, for example, two leg regions so that a transmitter 4 and a receiver 3 are situated in each cavity in a respective leg region in the rail direction, and a transmitter 4 and a receiver 3 are situated also in a respective leg region counter to the rail direction.

(27) An absorber 7 is situated in each cavity between the two leg regions in the rail direction, e.g., in accordance with the configuration described for the example embodiment illustrated in FIGS. 1 to 3. Especially for light, the cavity is thus separated with the aid of absorber 7. Light that propagates in front of the mobile part in the rail direction is separated from the spatial region disposed behind the mobile part.

(28) With the aid of the system illustrated in FIGS. 4 to 6, a duplex method is therefore obtainable as a data transmission between two mobile parts because a transmission is able to be carried out in a first one of the cavities, and the receiving for respective mobile part 40 can be obtained in the other. The same applies to the data transmission between the stationary transmitter 2 and receiver 1 and a mobile part 40, i.e., a transmitter 4 and a receiver 3.

(29) In further exemplary embodiments, the respective profiled part 5, 41 is produced from a metal such as aluminum. The surface of the material bordering the respective cavity thus is reflective for the radiation, i.e., especially visible or infrared light. As an alternative, the respective profiled part 5, 41 may be produced from plastic, and thus especially as a profiled plastic part. The surface of the material bordering the respective cavity is, for example, coated with a layer that reflects the radiation, e.g., coated with a chromium layer or a chromium-containing layer.

(30) In further exemplary embodiments, the rail and the profiled part 5, 41 are formed from the same material and thus are integrally configured, i.e., as one part. Thus, the cavity or cavities on the rail is/are provided in integrated form. When the rail system is produced, only the rail thus needs to be installed. The mobile parts 6, 40 are then placed on the rail and project via their leg regions into the cavities so that transmitters 4 and receivers 3 disposed in the leg regions emit radiation into the cavities.
