Further advantages emerge from the subclaims. The invention is not limited to the combination of features of the claims. For the expert, further meaningful combination options of claims and / or individual arise

Claim features and / or features of the description and / or figures, in particular from the task and / or the task by comparison with the prior art task.

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

FIG. 1 shows a section of a rail system which has a switch 3.

FIG. 2 shows a cross section through the rail profile in the region of a vehicle traveling on the rail. FIG. 3 shows an associated side view.

FIG. 4 shows a schematic representation of the coupling of high frequency into rail sections of the rail system. As shown in Figure 1, the system has rail parts on which a vehicle 2 is movable. In this case, at least one passive switch 3 is provided, which must traverse the vehicle 2. The switch 3 is moved by an actuator either in a first or second point position. By means of this method, the corresponding turnout piece to be activated is brought into position.

The rail 4 also has a slot waveguide profile 24, as shown in more detail in Figure 2. An antenna 1 protrudes into the slot of the slot waveguide profile 24 which is open to the outside, so that electromagnetic waves can be coupled in and out. At some points of the rail system stationary arranged means for coupling and / or decoupling of the waves are arranged.

Since in the rail direction in the region B of the switch of the slot waveguide has no stationary means arranged for coupling and / or decoupling, is also no

Data exchange with the vehicle executable.

Therefore, the vehicle 2 in the rail direction at a distance A antennas 1, wherein the distance A is longer than the area B. Thus, also in the switch area

Data exchange allows, although the points pieces have no slot waveguide and only the outside of the turnout area located rail profile parts

Have slot waveguide regions. As can be seen clearly in FIG. 2, the slot waveguide region 24 is in one piece on the

Profile rail part 23 formed. Thus, it can be produced without additional effort together with the profile rail part 23 as a continuous casting.

In this case, the profile rail part 23 has a central wall, which has Abrollbereiche for wheels of the vehicle 20 at its top and bottom.

In this case, on the one hand on the upper side a Abrollbereich for a support wheel 22 is arranged, which at least partially derives the weight of the vehicle 20 to the profile rail part 23.

On the side are Abrollbereiche for the lateral guide wheels 21 of the vehicle 20th

arranged. Also on the underside of such lateral guide wheels are rolling on Abrollbereichen, said Abrollbereiche at least partially the outer surface of the

Slot waveguide 24 represent.

The slot waveguide 23 is arranged in a spur-symmetrical manner, that is to say it has a plane of symmetry which is arranged centrally to the left and right rolling regions for the lateral guide wheels 21, as seen in the rail direction. Thus, if a rolling area, for example the left rolling area, is mirrored for lateral guidance on a plane of symmetry, it moves into another rolling area, in particular the right rolling area.

This central arrangement of the slot waveguide region 24 to the rail track allows the vehicle to an antenna 25 is arranged, which is also the center of the

Schlitzhohlleiterberiech 24, in particular centrally to the downwardly directed opening, so slot is arranged.

On the central wall of the profile rail part 23 and undercuts are formed so that a holding part 27 can be clipped, which is preferably made of plastic and in which primary conductor lines are clipped. The primary conductor is electrical

Schlappe laid, in which a medium-frequency alternating current is impressed. In this case, a frequency between 10 kHz and 1000 kHz is advantageous. Towards the vehicle, the leading part of the loop is excellent, and closer to the wall, the return part of the loop can be clipped into the holding part 27. The leading part, ie, the lead, becomes the clip-in area 28 for primary conductors, in particular line conductors, clipped and the return part, ie return conductor, in the Einklipsbereich 29 for primary conductors, in particular line conductors.

On the vehicle, a secondary winding is provided, which is inductively coupled to the primary conductor, wherein the secondary winding such a capacitance is connected in parallel and / or in series, that the associated resonant frequency substantially corresponds to the frequency of the impressed in the primary conductor alternating current. Thus, energy is transferable with a high efficiency, especially in the case of deviations from the position of the maximum inductive coupling.

In addition, a track transmitter is arranged on the holding part 27 or alternatively on the profile rail part 23, such as bar code, so that by means of a corresponding reader or sensor, a determination of the position of the vehicle in the rail system is executable. A preferred location for attaching the track transmitter in the alternative embodiment, the cheeks of the profile rail part 23, wherein the cheeks have the Abrollbereiche for the lateral guide wheels. The cheeks are perpendicular to the rail direction and perpendicular to the axis of the lateral

Extended running guide wheels, so that there is enough surface available, where then the distance encoder can be applied, for example, is glued.

As shown in FIG. 3, the vehicle has a front wheel, that is to say the drive wheel 31, which is driven by an electric motor 30, and a rear wheel, which functions as a mere carrying wheel 32. In order to enable driving through curves, the vehicle has a first rigid module which has the electric motor 30 and on which the drive wheel 31 is mounted. Another module comprises the storage for the bare support wheel 32. The two modules are connected via a connecting part 33, wherein in

Connecting region is arranged a pivot bearing whose axis of rotation perpendicular to

Rail direction and perpendicular to the axis of the lateral guide wheels 21 is aligned. At the two modules, the respective antenna 25 is fastened by means of a holding part 34. In this case, the antenna 25 projects into the opening of the slot waveguide in the region X.

Preferably, the position of the intrusion center is selected to the support wheel or drive wheel 31, whereby the antenna 25 is arranged in the region of the axis of rotation between the module and connecting part 33. Thus, when driving through curves, the antenna 25 is always aligned and arranged centrally to the opening. The farther the antenna 25 is located away from the axis of rotation, the further it deviates from the central position for opening the slot waveguide 24 when cornering. As shown in Figure 4, the rail system has an access point 47, with a high-frequency signal for data transmission to splitter is transferable. In this case, the signal originating from the access point 47 is split several times over the splitter 46 shown in FIG. 4, so that the signal can be fed to the various rail sections (40, 41, 42, 43, 44, 45). FIG. 4 shows a sixfold splitting. Preferably, the signal split by a splitter 46 becomes stationary in a rail of one

arranged, arranged centrally in the slot waveguide region antenna device irradiated in two opposite directions. Thus, many rail sections are of only a single access point 47, that is, of only a single associated

Radio modem, with the high-frequency signal for data transmission supplied.

In this way, from an access point 47, a large area, so radio cell supplied, which frequent radio cell changes when moving the vehicles in the rail system can be avoided. By avoiding the failure-prone

Radio cell change, the error rate during data transmission can be reduced.

Through the integration of the slot waveguide 24 in the lower cheek area of the

Rail profile part 23 is a retrofitting of old systems without slot waveguide executable in a simple manner, without the need to modify the vehicles - with the exception of the antennas and data transmission means to be installed.
