The advantage here is that a stable attachment of the sensor can be carried out such that the sensor has as constant a distance from the rail part when cornering, especially so also of components such as coding, slot waveguide and / or busbars.

In an advantageous embodiment, the component is an encoding and / or a slot waveguide and / or one of the components as busbars,
in particular, wherein the coding, the busbars and / or the slot of the slot waveguide in the rail direction extend or extend parallel to the rail direction. It is advantageous in this context that the vehicle can be supplied by means of a conductor rail, data transmission with a high data stream can be carried out by means of a slot waveguide, and simple position identification can be carried out by means of coding.

In an advantageous embodiment, the images taken by the sensor from the slot waveguide images are evaluated by the evaluation each such that deformations of the slot waveguide can be seen, ie in particular impermissibly large deviations from a desired shape of the slot waveguide. The advantage here is that a simple monitoring by means of image recognition is executable.

For the skilled person, further meaningful combination options of claims and / or individual claim features and / or features of the description and / or figures, in particular from the task and / or posing by comparison with the prior art task.

The invention will now be explained in more detail with reference to figures:

In the 1 an area of a rail system according to the invention is shown.

As in 1 shown, the vehicle has at least one frame 2 on, on which a rolling on a stationary rail part, on the frame 2 the vehicle rotatably mounted impeller 1 is arranged.

The rail part 4 is manufactured as extruded section, in particular aluminum extruded section. At him is a slot waveguide 5 arranged so that the slot direction is aligned parallel to the rail direction and a vehicle-mounted antenna at least partially protrudes into the hollow portion of the slot waveguide. In this way, data between a stationary unit and the vehicle by means of electromagnetic waves can be transmitted, which after coupling in the slot waveguide 5 spread.

Also, on the frame 2 the vehicle also lateral guide wheels 10 arranged, which also roll on the rail part. However, the respective axis of rotation of a lateral guide wheel 10 transverse to the rail direction and perpendicular to the axis of rotation of the impeller 1 aligned, with the axis of rotation of the impeller 1 is also aligned transversely to the rail direction.

The frame 2 the vehicle has a first support beam area 7 of the frame 2 on which an upper portion of the frame 2 , which is the bearing of the impeller 1 receives, with a lower area, namely connecting area 9 , connects, the lower portion of a downwardly excellent receiving bolt 8th carries for receiving a crossbeam. By means of with a recess on the locating bolt 8th attachable crossbeam is another frame connectable, so that a rail vehicle can be formed, which two wheels 1 having.

The vehicle is electrically powered by a conductor rail. These are on the rail part 4 busbars 6 arranged, wherein the rail direction is aligned parallel to the busbar direction. On the vehicle, a corresponding current collector is arranged so that sliding contact between carbon brushes of the pantograph and the busbars 6 is provided. In this way, a drive motor is electrically powered, by means of soft example, the impeller 1 is drivable.

At the the Tragholmbereich 7 facing side of the rail part 4 is also a coding 3 mounted by a sensor disposed on the vehicle 12 is detectable.

The coding 3 is preferably printed on an adhesive tape, which on a correspondingly suitable adhesive surface of the rail part 4 is stickable. Alternatively, the encoding 3 also be applied to a plastic carrier, in particular stickable as adhesive tape or printable on the plastic carrier.

The coding 3 is preferably implemented as a data matrix code. Thus, at least two tracks of symbols are executed, the tracks being spaced apart in a direction transverse to the rail direction.

The sensor 12 is by means of a holding device 11 with adjustment function at the connection area 9 arranged.

Preferably, the holding device 11 at the connection area 9 attached, ie in the rail direction between the two spaced apart in the rail direction Tragholmbereichen 7 arranged. Thus, when cornering as constant as possible a distance between the sensor 12 and rail part, in particular coding 3 and slot waveguide 5 , reachable.

Thus, therefore, the position of the sensor 12 selected such that from the connection area 9 The area covered by the rail overlaps with that of the sensor 12 in the rail direction covered area.

The vehicle also includes a position determining system that determines the position of the vehicle.

The sensor 12 is preferably designed as a camera. Preferably, the sensor 12 aligned such that in his field of view, ie in its sensitive area, the coding 3 , the slot waveguide 5 and the busbars 6 are arranged.

Preferably, in this way of the evaluation unit of the slot waveguide 5 monitored and damage detected quickly. In particular, the opening slot of the slot waveguide becomes 5 supervised. In this case, impermissibly large deviations from the rectilinear course are monitored. Also a foreign body, which in the hollow portion of the slot waveguide 5 has arrived is detectable.

In addition, further sensors can be provided, the signal of which can also be fed to the evaluation unit, so that the signal from the camera can be evaluated as a function of the signal of the further sensors and the position signal. As an additional sensor, an acceleration sensor can be used, which is the acceleration sensor mounted on the vehicle, so that in an impermissibly strong acceleration, the associated signal of the camera is evaluated. The defective location can thus be displayed as an image - for example, on a display means, such as a screen on a higher-level control, which is used for data exchange by means of the slot waveguide 5 connected to the vehicle.

The acceleration sensor, in particular structure-borne noise sensor, can also be arranged on a part which projects into the hollow region of the slot waveguide. Thus, deformations, ie deformations, of the slot waveguide can be detected if, during a travel of the vehicle, a deflection of the part from its rest position is caused by the deformations. The respective deflection causes an acceleration of the part or at least a portion of the part and thus a corresponding sensor signal which can be stored together with the position signal. In this way, the respective deformation is assigned a position, so that a repair can be initiated in a targeted manner.

In addition, the reliability, so quality, in the detection can be determined. In this way, the camera generates a corresponding sensor signal which can be stored together with the position signal. In this way, the respective deformation is assigned a position, so that a repair of the coding 3 can be introduced in a targeted manner.

Likewise, by means of the camera, the busbars 6 monitored on deformation and in turn by means of the stored together position value repair prompt veranlassbar.

After a first test drive, this assignment of the number and the quality to the rail position is comparable to the data recorded and determined during further subsequent measurement runs. In this way, changes are recognizable. In particular, however, faulty symbols, ie codes, are recognizable or deformations of the slot waveguide 5 or the busbars 6 , Thus, the positions of the faulty symbols are storable and / or forwardable, in particular from the vehicle to a higher-level control, which stores this information and / or forwards it to another vehicle. Or alternatively, the symbols can be repaired, that is to say the coding at the corresponding location 3 repairable.

In order to obtain as constant a distance as possible and thus the most uniform possible evaluation, the sensor is 12 by means of the holding device 11 at the connection area 9 between the stringer sections 7 of the frame 2 arranged in such a way that the plane whose normal is the rail direction and which contains the axis of rotation of the impeller, the sensitive area of the sensor 12 , ie in particular the field of view of the sensor 12 , cuts.
