Die Erfindung wird nun anhand von Abbildungen näher erläutert: The invention will now be explained in more detail with reference to figures:
In der Figur 1 ist ein schematischer Aufbau eines erfindungsgemäßen In the figure 1 is a schematic structure of an inventive
Kommunikationsanordnung in Schnittansicht gezeigt. Communication arrangement shown in sectional view.
Figur 2 zeigt eine zugehörige Schrägansicht. FIG. 2 shows an associated oblique view.
Wie in den Figuren gezeigt ist ein Schlitzhohlleiterprofil 1 mit im Wesentlichem As shown in the figures, a slot waveguide profile 1 with in essence
rechteckförmigem Profilquerschnitt vorgesehen, welches in einer Anlage anordenbar ist. Vorzugsweise ist das Schlitzhohlleiterprofil an einem Schienenteil oder an einem mit einem Schienenteil verbundenen Halteteil angeordnet und parallel zur Schienenrichtung ausgerichtet. Somit ist ein Schienenfahrzeug, welches eine Antenne 4 aufweist entlang des Schienenteils verfahrbar und es sind Daten austauschbar zwischen einer elektronischen Anordnung des Schienenfahrzeugs, das mit der Antenne 4 elektrisch verbunden ist und somit mittels der Antenne 4 elektromagnetische Wellen einkoppelt und/oder auskoppelt in den Schlitzhohlleiter, und einer stationär angeordneten elektronischen Anordnung, welche zur Einkoppelung und/oder Auskoppelung von elektromagnetischen Wellen in den provided rectangular profile cross-section, which can be arranged in a system. Preferably, the slot waveguide profile is arranged on a rail part or on a holding part connected to a rail part and aligned parallel to the rail direction. Thus, a rail vehicle having an antenna 4 is movable along the rail part and data is exchangeable between an electronic arrangement of the rail vehicle, which is electrically connected to the antenna 4 and thus coupled by means of the antenna 4 electromagnetic waves and / or decoupled in the slot waveguide , And a stationary arranged electronic arrangement, which for the coupling and / or decoupling of electromagnetic waves in the
Schlitzhohlleiter ausgeführt ist. Dabei ragt die Antenne 4 des Schienenfahrzeuges zumindest teilweise in den Schlitz des Schlitzhohlleiters hinein und elektromagnetische Wellenanteile einkoppelbar oder auskoppelbar. Auf diese Weise ist die Datenübertragung ermöglicht. Slot waveguide is executed. In this case, the antenna 4 of the rail vehicle protrudes at least partially into the slot of the slot waveguide and electromagnetic wave components can be coupled or decoupled. In this way the data transfer is possible.
Die Antenne ist von einem elektrisch isolierenden Halteteil 5 des Schienenfahrzeuges gehalten. Am Schienenfahrzeug, insbesondere am Halteteil 5, ist auch ein Schirmblech 3 befestigt, welches zur Abschirmung von anderen elektromagnetischen Strahlungsquellen ausgeführt ist. The antenna is held by an electrically insulating holding part 5 of the rail vehicle. On the rail vehicle, in particular on the holding part 5, and a shield plate 3 is fixed, which is designed to shield from other electromagnetic radiation sources.
Dabei weist das Schirmblech 3 einen U-förmiges Profil im Querschnitt auf, wobei die Normalenrichtung der Querschnittsebene in Schienenrichtung beziehungsweise In this case, the shroud 3 has a U-shaped profile in cross section, wherein the normal direction of the cross-sectional plane in the rail direction or
Leiterrichtung des Schlitzhohlleiters ausgerichtet ist. In und entgegen der Schienenrichtung ist das Schirmblech beidseitig offen, so dass das Schienenfahrzeug ungehindert verfahrbar ist. Conductor direction of the slot waveguide is aligned. In and against the rail direction, the shield plate is open on both sides, so that the rail vehicle is freely movable.
Das Schirmblech 3 ist vorzugsweise aus Kupfer, Stahl und/oder Aluminium gefertigt. Der Schlitz ist umrandet von einem Kaminabschnitt 2, der die Schlitzöffnung quer zur Schienenrichtung quasi kragenförmig begrenzt. Das Schirmblech 3 deckt den Kaminabschnitt 2, also den Kragen, von außen in Querrichtung gesehen, also in einer Richtung welcher quer zur Schienenrichtung und quer zur The shielding plate 3 is preferably made of copper, steel and / or aluminum. The slot is surrounded by a chimney section 2, which limits the slot opening transversely to the rail direction quasi collar-shaped. The shroud 3 covers the chimney section 2, ie the collar, seen from the outside in the transverse direction, ie in a direction which is transverse to the rail direction and transverse to the
Normalenrichtung der Schlitzöffnung, also in derjenigen Richtung, in welcher die Antenne 4 in den Schlitz zumindest teilweise hineinragt, ab. Somit umgibt das Schirmblech 3 den Kaminabschnitt 2 von außen zumindest teilweise. Normal direction of the slot opening, ie in the direction in which the antenna 4 at least partially protrudes into the slot from. Thus, the shroud 3 surrounds the chimney section 2 from the outside at least partially.
Etwaige, in der Umgebung angeordnete Strahlungsquellen sind deshalb gut abgeschirmt, da das Schirmblech 3 und/oder der Kaminabschnitt 2 jede geradlinige Verbindungslinie zwischen der Strahlungsquelle und einem Oberflächenpunkt der Antenne unterbricht. Somit ist nur eine Ausbreitung der elektromagnetischen Wellen zwischen der Strahlungsquelle und der Antenne 4 möglich unter Wechselwirkung mit dem Material des Schirmblechs 3 und/oder mit dem Material des Schlitzhohlleiters. Any radiation sources arranged in the vicinity are therefore well shielded, since the shielding plate 3 and / or the chimney section 2 interrupts any rectilinear connection line between the radiation source and a surface point of the antenna. Thus, only a propagation of the electromagnetic waves between the radiation source and the antenna 4 is possible in interaction with the material of the shielding plate 3 and / or with the material of the slot waveguide.
