Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Antennenanordnung zwischen Fahrzeug und Gleisbereich nach dem Oberbegriff des Patentanspruchs 1 bzw. 5.The present invention relates to a method and an antenna arrangement between the vehicle and the track area according to the preamble of
Die vorliegende Erfindung bezieht sich auf die Datenübertragung in der Eisenbahntechnik zwischen einem Geleise als ortsfeste Einrichtung und mindestens einem schienengebundenen Fahrzeug.The present invention relates to data transmission in railway engineering between a track as a stationary device and at least one rail-bound vehicle.
Dazu werden Strahlungskabel eingesetzt. Das sind üblicherweise Koaxialkabel mit einem speziellen Aussenleiter, welche die Auskopplung eines magnetischen Feldes erlauben. Andere Anordnungen benutzen einen einadrigen Leiter, welcher in Schleifen ausgelegt ist und in geeigneten Abständen ausgekreuzt ist.For this purpose, radiation cables are used. These are usually coaxial cables with a special outer conductor, which allow the coupling of a magnetic field. Other arrangements use a single-core conductor which is loops and is crossed at appropriate intervals.
Insbesondere im Bahnhofbereich werden auf diese Weise sicherheitsrelevante Daten, wie zum Beispiel die Halteposition oder Daten zur Abfahrtsverhinderung übertragen. Dort muss das Fahrzeug mit sicherheitsrelevanten Daten aus dem Zugleitprozess, wie beispielsweise der zu erreichenden Halteposition, der Geschwindigkeitslimite und Daten zur Abfahrtverhinderung versorgt werden. Diese Daten können von Einflussgrössen wie Fahrzeuggewicht, Zuglänge, Bremssystem und Witterung abhängig sein.In particular, in the station area security-relevant data, such as the stop position or data for departure prevention are transmitted in this way. There, the vehicle must be supplied with safety-relevant data from the Zugleitprozess, such as the stop position to be reached, the speed limit and data for departure prevention. These data may depend on influencing factors such as vehicle weight, train length, brake system and weather conditions.
Neben sicherheitsrelevanten Daten sind weitere Daten, wie Prozessdaten und Zustandsinformation des Zuges respektive der Lokomotive für eine Übermittlung an die für die Infrastruktur zuständige Stelle von Interesse. So können zum Beispiel bei einem Ausfall einer Funktion wie z.B. einem Antriebsmotor spezifische Daten versendet werden. Aber auch für Fahrgastabrechnungssysteme oder Intrusionssysteme (Einbruch und Vandalismus in Fahrzeugen) ist eine Datenübermittlung vom Fahrzeug nach aussen von Interesse. Für Up Link Anwendungen ist die Fahrgast- Platzreservierung beispielhaft zu nennen. Für diese Aufgaben soll die bestehende Infrastruktur weitgehend genutzt werden.In addition to safety-relevant data, further data, such as process data and status information of the train or of the locomotive, are of interest for transmission to the authority responsible for the infrastructure. For example, in the event of a failure of a function such as a drive motor, specific data may be sent. But also for passenger billing systems or intrusion systems (burglary and vandalism in vehicles) is a data transfer from the vehicle to the outside of interest. For uplink applications is the passenger seat reservation as an example. For these tasks, the existing infrastructure should be widely used.
Mit den für die Loopfunktion verwendeten Koaxialkabeln besteht das Problem der Gewährleistung der Sicherheit, wenn zusätzlich zur Zug-Sicherungsinformation noch weitere für den Bahnbetrieb relevante Daten zwischen Fahrzeug und Systemtechnik zusätzlich auf dem gleichen Leiter ausgetauscht werden. Die Anforderungen der erforderlichen Trennung und damit Unbeeinflussbarkeit sind nicht mehr gegeben.
In der Praxis zeigt sich auch, dass die Koaxialkabel mit ihrem nicht symmetrischen Aufbau gegen eine metallische leitfähige Umgebung wesentliche Nachteile durch die kapazitive und induktive Kopplung des Aussenleiters mit konstruktiven Elementen wie der Schiene und Weichen aufweisen. Es entstehen unkontrolliert Strompfade, welche ein zusätzliches H-Feld erzeugen, welches meist Interferenzen hervorruft.With the coaxial cables used for the Loopfunktion there is the problem of ensuring safety, if in addition to the train security information other relevant for railway operation data between the vehicle and system technology are also exchanged on the same head. The requirements of the required separation and thus uninfluenceability are no longer given.
In practice, it also shows that the coaxial cable with its non-symmetrical structure against a metallic conductive environment have significant disadvantages due to the capacitive and inductive coupling of the outer conductor with constructive elements such as the rail and points. It creates uncontrolled current paths, which generate an additional H-field, which usually causes interference.
Aus der Schrift
In der Fachwelt wird zwischen den Begriffen verdrillt und verseilt unterschieden. Einheitlich ist die Handhabung in der Praxis nicht. In dieser Schrift fallt unter den Begriff verdrillt jede Anordnung, die eine helixförmige Leiterstruktur aufweist, beispielsweise auch die in der Fachwelt gelegentlich speziell angesprochenen Begriffe der Verseilung, Viererverseilung, Lagenverseilung und Dieselhorst-Martin-Verseilung. In der Wirkung auf das erfinderische Verfahren und die Anordnung besteht kein prinzipieller Unterschied.In the professional world, a distinction is made between the terms twisted and stranded. Uniform handling in practice is not. In this document falls under the term twisted any arrangement that has a helical conductor structure, for example, the occasionally specifically discussed in the art terms of stranding, quad stranding, layer stranding and Dieselhorst-Martin stranding. In effect on the inventive method and the arrangement is no fundamental difference.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Antennenanordnung anzugeben, die es erlaubt, unter weitgehender Nutzung vorhandener Infrastruktur zusätzliche Daten zwischen Fahrzeug und Schiene zu übertragen, ohne die Sicherheitsanforderungen für die Übertragung der sicherheitsrelevanten Daten unzulässig zu beeinträchtigen.The present invention has for its object to provide an antenna arrangement that allows to transfer additional data between the vehicle and rail while largely using existing infrastructure, without unduly compromising the security requirements for the transmission of security-related data.
Diese Aufgabe wird durch die im Patentanspruch 1. angegebenen Massnahmen gelöst.This object is achieved by the measures specified in claim 1..
Die erfindungsgemässe Antennenanordnung, wonach
das eine Leiterpaar (1, 2) im Kern (7) des Kabels (20) und das andere Leiterpaar (1, 2) in einem hohlzylinderförmigen Segment um den Kern (7) angeordnet ist,
erlaubt eine Übertragung zusätzlicher Daten, ohne unzulässige Beeinflussung sicherheitsrelevanter Daten. Die streckenseitige Antennenanordnung, für welche ein weiterer getrennter Kanal zur Übertragung weiterer Daten bereitgestellt ist, für welchen ein weiteres Leiterpaar vorhanden ist, erlaubt dabei die Nutzung bestehender Infrastruktur.The inventive antenna arrangement, according to which
the one conductor pair (1, 2) is arranged in the core (7) of the cable (20) and the other conductor pair (1, 2) is arranged in a hollow cylindrical segment around the core (7),
allows transmission of additional data without undue influence on security-relevant data. The track-side antenna arrangement, for which a further separate channel is provided for the transmission of further data for which there is another pair of conductors, allows the use of existing infrastructure.
Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.Advantageous embodiments of the invention are specified in further claims.
Durch die folgenden Merkmale einzeln oder in Kombination untereinander kann die Zuverlässigkeit und/oder die Übertragungskapazität von der Datenübertragung zusätzlich erhöht werden und/oder besonders einfach und kostengünstig hergestellt werden:
- i) Betreiben der verschiedenen Kanäle auf verschiedenen Frequenzen. Dadurch lassen sich insbesondere Interferenzphänomene vermeiden. Massnahmen zur Verhinderung einer gegenseitigen Beeinflussung können klein gehalten werden oder fallen gänzlich weg.
- ii) Verdrillung von Leiterpaaren untereinander und/oder miteinander. Bei einer geeigneten Wahl der Schlaglänge heben sich dabei die unterschiedlichen Einflüsse eines elektromagnetischen Felds auf die Hin- und die Rückleitung eines Leiterpaars im Wesentlichen auf.
- iii) Vermeidung von Sekundärströmen durch eine geeignete geometrische Anordnung der Leiter im Kabel.
- iv) Symmetrische Anordnung von Leiterpaaren im Kabel. Dadurch können insbesondere elektromagnetische Kopplungen zwischen diesem Leiterpaar und seiner Umgebung, insbesondere jedoch der Kabelumgebung reduziert werden.
- v) Anordnung der Leiter im Kabel so, dass in einem Querschnitt durch das Kabel ein Leiterpaar im Wesentlichen in einem Bereich in der Nähe der Verbindungslinie des anderen Leiterpaars, jedoch ausserhalb der Verbindungsstrecke dieses anderen Leiterpaars angeordnet ist (
Fig. 10 ). In diesem Bereich zeigen die magnetischen Feldvektoren im Wesentlichen in entgegensetzte Richtungen und heben sich daher teilweise auf. - vi) Alle Leiter weisen den genau gleichen Schlag auf. Damit weist ein beliebiger Leiter an jeder Stelle entlang des Kabels zu jedem der weiteren Leiter im Kabel eine konstante Koppelgrösse auf.
- vii) Betreiben der verschiedenen Kanäle mit unterschiedlichen Modulationsverfahren.
- viii) Nutzung eines Kabels in dem die für Übertragungs-Leiterschleifen nicht genutzten Leiter durch vereinfachte Substitute/Platzhalter aus Kunststoff ohne elektrische Leiter ersetzt werden.
- i) operating the different channels on different frequencies. As a result, in particular interference phenomena can be avoided. Measures to prevent mutual interference can be kept small or completely eliminated.
- ii) Twisting of pairs of conductors with each other and / or each other. In the case of a suitable choice of the lay length, the different influences of an electromagnetic field on the forward and return lines of a pair of conductors essentially cancel each other out.
- iii) Prevention of secondary currents by means of a suitable geometric arrangement of the conductors in the cable.
- iv) Symmetrical arrangement of conductor pairs in the cable. As a result, in particular electromagnetic couplings between this pair of conductors and its environment, but in particular the cable environment can be reduced.
- v) Arrangement of the conductors in the cable so that in a cross section through the cable, a conductor pair is arranged substantially in an area in the vicinity of the connecting line of the other pair of conductors, but outside the connection path of this other pair of conductors (
Fig. 10 ). In this region, the magnetic field vectors essentially point in opposite directions and therefore partially cancel each other out. - vi) All leaders have exactly the same beat. Thus, any conductor at any point along the cable to each of the other conductors in the cable has a constant coupling size.
- vii) operating the different channels with different modulation methods.
- viii) Use of a cable in which the conductors not used for transmission conductor loops are replaced by simplified plastic substitutes / placeholders without electrical conductors.
