Abstract

For a device used to decouple different communications systems for the transmission of information between track-bound vehicles and fixed stations, in which a line conductor is laid along the track and inductive short loops are disposed at specific points along the track, and in which the vehicles are equipped with antennas for inductive coupling with the line conductor and the short loops, the object is to avoid difficulties due to the magnetic coupling of the two systems. This is achieved by disposing a short loop over a conductor (1b) of the line conductor (1) in such way that its longitudinal sides (K11, K12) are laid at approximately the same distance from the conductor (1b) of the line conductor, the coupling factor between the line conductor and the respective short loop being zero. The main potential use of the invention is in railway automation. <IMAGE>

Description

Induktive Datenübertragung zwischen FahrzeugenInductive data transmission between vehicles

und streckenfesten Einrichtungen Die Erfindung bezieht sich auf eine Einrichtung zur Entkopplung von unterschiedlichen Nachrichtensystemen gemäß dem Oberbegriff des vorliegenden Patentanspruchs.and stretch-proof devices The invention relates to a Device for decoupling different messaging systems according to the Preamble of the present claim.

Es ist bekannt, längs einer Strecke Linienleiter zu verlegen, die mit einer ortsfesten Station verbunden sind. Fahrzeuge, die längs der Strecke verkehren, sind mit Antennen ausgerustet, die eine induktive Kopplung mit dem Linienleiter ermöglichen. Die Fahrzeuge sind mit Empfangs-/Sendeeinrichtungen ausgestattet, die über die Antenne des Fahrzeugs Informationen mit der ortsfesten Station austauschen können.It is known to lay line cables along a route that are connected to a fixed station. Vehicles traveling along the route, are equipped with antennas that have an inductive coupling with the line cable enable. The vehicles are equipped with receiving / transmitting devices that Exchange information with the stationary station via the vehicle's antenna can.

Es ist ferner bekannt, an bestimmten Streckenpunkten Eurzschleifen zu verlegen, z.B. zwischen den Schienen eines Gleises, in welehen in entsprechender Weise Informationen zwischen Fahrzeug und streckenfester Station-bei Vorbeifahrt des Fahrzeugs ausgetauscht werden können.It is also known to have Eurz loops at certain points on the route to be laid, e.g. between the rails of a track, in which the appropriate Wise information between the vehicle and the fixed station when driving by of the vehicle can be exchanged.

Sollen nun beide Ubertragungssysteme nebeneinander benutzt werden, so treten Schwierigkeiten durch die magnetische Kopplung und damit gegenseitige Beeinflussung beider Systeme auf.If both transmission systems are to be used next to each other, difficulties arise through the magnetic coupling and thus mutual Influencing both systems.

Der Erfindung liegt die Aufgabe zugrunde, diesen Schwierigkeiten zu begegnen und damit eine höhere Störsicherheit für die beiden Systeme zu erreichen.The invention is based on the object of addressing these difficulties and thus to achieve a higher immunity to interference for the two systems.

GemäB der Erfindung wird diese Aufgabe durch die Merkmale des Kennzeichens des vorliegenden Patentanspruchs gelöst.According to the invention, this object is achieved by the features of the label of the present claim solved.

Ein Ausführungsbeispiel für die Einrichtung gemäß der Erfindung wird an Hand der Zeichnung nachstehend näher beschrieben.An embodiment for the device according to the invention is described in more detail below with reference to the drawing.

In der Fig. 1 sind mit la, Ib zwei Leiter eines Linienleiters 1 bezeichnet, die längs einer Strecke verlegt sind, den Abschlußwiderstand 2 besitzen und mit einer streckenfesten Station 3 verbunden sind. Längs der Strecke bewegen sicheinrahrzeug F, das mit dem Linienleiter mittels einer Rahmenantenne A induktiv gekoppelt ist, welche ihrerseits mit einer Fahrzeugsende- und -empfangseinrichtung FG verbunden ist. Ferner ist eine Kurzschleife E vorhanden, über die punktförmig Informationen zu einer ortsfesten Station 4 bei Vorbei fahrt des Fahrzeugs an der Kurz schleife E übertragen werden können. Bei dieser Art der Verlegung des Linienleiters 1 und der Kurz schleife K findet eine magnetische Kopplung des Linienleiters mit der Kurz schleife und damit ein Ubersprechen statt: sendet z.B. die Fahrzeugantenne mit einer Frequenz f1 an die Strecke, so erfolgt auch in der Schleife E ein ständiger Empfang dieser Frequenz aufgrund der magnetischen Kopplung des Linienleiters mit der Kurzschleife K. Durch das Ubersprechen des Linienleiters auf die Kurz schleife ist eine Falschmeldung über die Kurzschleife nicht auszuschließen.In Fig. 1, two conductors of a line conductor 1 are designated by la, Ib, which are laid along a route, have the terminating resistor 2 and with a fixed station 3 are connected. Einrahrzeug move along the route F, which is connected to the line cable by means of a Loop antenna A inductive is coupled, which in turn with a vehicle transmitting and receiving device FG is connected. There is also a short loop E over which it is punctiform Information on a fixed station 4 when the vehicle drives past the Short loop E can be transmitted. With this type of routing of the line cable 1 and the short loop K finds a magnetic coupling of the line cable the short loop and thus crosstalk takes place: e.g. transmits the vehicle antenna with a frequency f1 to the path, there is also a constant in loop E. Reception of this frequency due to the magnetic coupling of the line cable the short loop K. By crosstalking the line conductor on the short loop a false report via the short loop cannot be ruled out.

Die erfindungsgemäße Lösung zeigt die Fig. 2, in der gleiche Bezugszeichen wie in Fig. 1 verwendet werden: die Eurzschleife E ist Jetzt so an der Strecke verlegt, daß sie derart über einen Leiter Ib des Linienleiters 1 angeordnet ist, daß ihre Längsseiten Kl1 und K12 in annähernd gleichem Abstand von dem Leiter Ib des Linienleiters 1 verlegt sind, wobei der Kopplungsfaktor zwischen dem Linienleiter und der Jeweiligen Kurz schleife Null wird. Durch diese Verlegung kommt es zur Nullkopplung zwischen Linienleiter und Kurzschleife. Die Fahrzeugantenne A hat auch bei der üblichen Anbringung symmetrisch zu den Leitern des Linienleiters Kopplung mit der Schleife. Zur optimalen Kopplung mit beiden Systemen-ist eine geänderte Anbringungsart zu wählen. Dies gilt auch für die Benutzung einer Perritantenne.The solution according to the invention is shown in FIG. 2, in which the same reference numerals as used in Fig. 1: the Eurzschleife E is now laid along the route, that it is arranged over a conductor Ib of the line conductor 1 that its Long sides Kl1 and K12 at approximately the same distance from the conductor Ib of the line conductor 1 are laid, whereby the coupling factor between the line cable and the respective Short loop becomes zero. This relocation results in a zero coupling between Line cable and short loop. The vehicle antenna A also has the usual Attachment symmetrical to the conductors of the line cable coupling with the loop. To the optimal Coupling with both systems - a different type of attachment must be selected. this applies also for the use of a Perrit antenna.

Bei Verwendung einer solchen Antenne ist ein Anbringen über den Leiter Ib nicht zulässig.When using such an antenna, it is attached over the conductor Ib not allowed.

Die Vorteile dieser Einrichtung bestehen in der Reduzierung des Ubersprechens, in der Vermeidung von zusätzlicher Dämpfung des Linienleitersystems und in der Einsparung von Selektionsmitt eln.The advantages of this facility are the reduction in crosstalk, in avoiding additional attenuation of the line cable system and in saving of selection tools.
