ZugbeeinflussungseinrichtungTrain control device
Die Erfindung bezieht sich auf eine Zugbeeinflussungseinrichtung für ein Gleis, mit der zwischen einer Leitstelle der Zugbeeinflussungseinrichtung und auf dem Gleis befindlichen Schienenfahrzeugen über einen gleisseitigen Leiter und Antennen der Schienenfahrzeugen Daten übertragen werden.The invention relates to a train control device for a track, with which data is transmitted between a control center of the train control device and rail vehicles located on the track via a track-side conductor and antennas of the rail vehicles.
Eine Zugbeeinflussungseinrichtung dieser Art ist beispielsweise aus der Druckschrift „Linienförmige Nachrichtenübertragung für Sicherungssysteme von Schienenbahnen" (H. Fricke, P. Form, Nachrichtentechnische Fachberichte NTF Fernwirktechnik VII, Band 34, 1967, S. 81 bis 86) bekannt. Bei dieser Zugbeeinflussungseinrichtung sind die gleisseitigen Leiter entweder in Form von Linienleitern separat im Gleis angebracht oder durch die Schienen selbst gebildet. Die Daten werden über die gleisseitigen Leiter in einem Frequenzbereich von einigen hundert Hz bis einigen 10 kHz zwischen einer Leitstelle und den Schienenfahrzeugen übertragen, wobei durch die gewählte Frequenz die maximal mögliche Übertragungslänge für die Zugbeeinflussungseinrichtung vorgegeben ist, da die Signaldämpfung mit steigender Frequenz zunimmt.A train control device of this type is known, for example, from the publication "Linear communication for railroad security systems" (H. Fricke, P. Form, NTF Fernwirktechnik VII, Volume 34, 1967, pp. 81 to 86) Track-side conductors either attached separately in the form of line conductors in the track or formed by the rails themselves.The data are transmitted via the track-side conductors in a frequency range from a few hundred Hz to a few 10 kHz between a control center and the rail vehicles, with the frequency chosen being the maximum possible transmission length for the train control device is specified, since the signal attenuation increases with increasing frequency.
Bei der vorbekannten Zugbeeinflussungseinrichtung tritt bei elektrifizierten Gleisen das Problem auf, daß die über die Schienen abfließenden Fahrströme der Schienenfahrzeuge Störfrequenzen aufweisen, die die Datenübertragung zwischen Schienenfahrzeugen und Zugbeeinflussungseinrichtung beeinträchtigen. Besonders große Störungen der Datenübertragung treten bei einer Besetzung des Gleises durch zwei oder mehr Schienenfahrzeuge auf, da dann die Antennen der Schienenfahrzeuge nicht nur die Fahr- bzw. Störströme, des jeweils eigenen Schienenfahrzeugs, sondern zusätzlich auch die Störströme der jeweils anderen Schienenfahrzeuge empfangen; dies kann u. U.
2 sogar dazu führen, daß eine Datenübertragung bei mehreren Schienenfahrzeugen auf dem Gleis unmöglich wird.In the known train control device, the problem arises with electrified tracks that the running currents flowing off the rails of the rail vehicles have interference frequencies which impair the data transmission between rail vehicles and the train control device. Particularly large disruptions in data transmission occur when the track is occupied by two or more rail vehicles, since then the antennas of the rail vehicles not only receive the driving or interference currents of the respective own rail vehicle, but also also the interference currents of the other rail vehicles; this can U. 2 even lead to the fact that data transmission with several rail vehicles on the track becomes impossible.
Der Erfindung liegt die Aufgabe zugrunde, eine Zugbeeinflussungseinrichtung der eingangs angegebenen Art dahingehend fortzuentwickeln, daß eine besonders zuverlässige Datenübertragung auch dann ermöglicht wird, wenn sich mehrere Schienenfahrzeuge auf dem elektrifizierten Gleis der Zugbeeinflussungseinrichtung aufhalten.The invention has for its object to develop a train control device of the type specified in such a way that a particularly reliable data transmission is made possible even when several rail vehicles are on the electrified track of the train control device.
Diese Aufgabe wird bei einer Zugbeeinflussungseinrichtung der eingangs angegebenen Art erfindungsgemäß dadurch gelöst, daß die Zugbeeinflussungseinrichtung elektrische Filter aufweist, die in vorgegebenen Abständen elektrisch jeweils zwischen einen Rückleiter des elektrifizierten Gleises und Erde geschaltet sind und hinsichtlich des von der Zugbeeinflussungseinrichtung genutzten Frequenzbereiches niederohmig sind.This object is achieved according to the invention in a train control device of the type specified at the outset in that the train control device has electrical filters which are electrically connected at predetermined intervals between a return conductor of the electrified track and earth and are low-impedance with regard to the frequency range used by the train control device.
Der wesentliche Vorteil der erfindungsgemäßen Zugbeeinflussungseinrichtung besteht darin, daß das zugehörige Gleis durch die elektrischen Filter in einzelne Gleissegmente unterteilt wird; durch die elektrischen Filter werden die in einem Gleissegment durch ein Schienenfahrzeug erzeugten Störströme nämlich vom Rückleiter des Gleises - beispielsweise der Schiene - sofort zur Erde abgeleitet, so daß die Nachbarsegmente des jeweiligen Gleissegmentes nahezu frei von diesen Störströmen bleiben. Ein Überkoppeln von Störströmen eines Gleissegmentes zum jeweils nächsten Gleissegment ist bei der erfindungsgemäßen Zugbeeinflussungseinrichtung also nur in geringem Umfang möglich, so daß sich mehrere auf einem Gleis aufhaltende Schienenfahrzeuge untereinander im Hinblick auf die Datenübertragung nicht beeinträchtigen können, solange sich diese in jeweils unterschiedlichen Gleis- Segmenten aufhalten.
Besonders einfach und damit vorteilhaft lassen sich die elektrischen Filter herstellen, wenn diese aus elektrischen Schwingkreisen gebildet sind, die mindestens einen Kondensa- tor und mindestens eine Spule aufweisen.The main advantage of the train control device according to the invention is that the associated track is divided into individual track segments by the electrical filters; by means of the electrical filter, the interference currents generated in a track segment by a rail vehicle are in fact immediately diverted from the return conductor of the track - for example the rail - to earth, so that the neighboring segments of the respective track segment remain almost free of these interference currents. Overcoupling interference currents from one track segment to the next track segment is therefore only possible to a limited extent in the train control device according to the invention, so that several rail vehicles on one track cannot interfere with one another with regard to data transmission, as long as they are in different track segments stop. The electrical filters can be produced particularly simply and therefore advantageously if they are formed from electrical resonant circuits which have at least one capacitor and at least one coil.
Eine andere einfache und damit vorteilhafte Ausführungsform der elektrischen Filter zeichnet sich dadurch aus, daß die Filter nur durch eine Kapazität gebildet sind. Bei dieser Ausführungsform lassen sich die Störsignale besonders gut ableiten, wenn die Kapazität einige Zehn μF groß ist.Another simple and thus advantageous embodiment of the electrical filter is characterized in that the filters are formed by only one capacitance. In this embodiment, the interference signals can be derived particularly well if the capacitance is a few tens of μF.
Besonders kostengünstig und damit vorteilhaft lassen sich die Daten zwischen Schienenfahrzeug und Zugbeeinflussungseinrich- tung übertragen, wenn der gleisseitige Leiter durch die Schienen des Gleises gebildet ist.The data can be transmitted between the rail vehicle and the train control device in a particularly cost-effective and thus advantageous manner if the track-side conductor is formed by the rails of the track.
Besonders zuverlässig lassen sich die Daten übertragen, wenn der gleisseitige Leiter durch im Gleis angebrachte Linienlei- ter gebildet ist.The data can be transmitted particularly reliably if the track-side conductor is formed by line conductors attached to the track.
Zur Erläuterung der Erfindung ist inTo explain the invention is in
Figur 1 ein Ausführungsbeispiel für eine erfindungsgemäße Zugbeeinflussungseinrichtung und in Figur 2 ein Teil eines weiteren Ausführungsbeispiels für die erfindungsgemäße Zugbeeinflussungseinrichtung dargestellt.Figure 1 shows an embodiment for a train control device according to the invention and in Figure 2 shows a part of another embodiment for the train control device according to the invention.
Figur 1 zeigt eine Zugbeeinflussungseinrichtung 3 für ein Gleis 7. Die Zugbeeinflussungseinrichtung 3 weist eine Leit- stelle 9 auf, die über Verbindungsleitungen 12 mit gleisseitigen Leitern 15 in Form von im Gleis 7 angebrachten Linienleitern verbunden ist. Die Linienleiter 15 weisen Kreuzungspunkte 18 auf, die auf dem Gleis 7 befindlichen Schienenfahrzeugen eine Ortsbestimmung in bekannter Weise ermöglichen. Auf dem Gleis 7 befinden sich zwei elektrisch angetriebene
4 Schienenfahrzeuge, und zwar ein Schienenfahrzeug 21 sowie ein weiteres Schienenfahrzeug 22, die jeweils Antennen 23 mit einer Empfangs-/Sendeeinheit 24 aufweisen. Über die Linienleiter 15 und die Antennen 23 werden zwischen der Zugbeein- flussungseinrichtung 3 und den Schienenfahrzeugen 21 und 22 Daten übertragen; mit elektrischer Antriebsenergie versorgt werden die Schienenfahrzeuge 21 und 22 über einen nicht dargestellten Fahrdraht, mit dem sie über Kontaktelemente in Verbindung stehen. Die beiden Schienenfahrzeuge 21 und 22 sind räumlich durch elektrische Filter 25 voneinander getrennt. Die elektrischen Filter 25 sind jeweils zwischen Erde 26 und die als Rückleiter wirkenden Schienen des Gleises 7 geschaltet und teilen das Gleis 7 in voneinander getrennte Gleissegmente 23, 30 und 32 auf. Die Länge der Gleissegmente ist durch unterschiedliche Faktoren vorgegeben, sie kann beispielsweise der durchschnittlichen Länge der Schienenfahrzeuge entsprechen. Der gleisseitige Anschluß der elektrischen Filter 25 kann direkt an einer der beiden durch einen Kurzschlu3verbinder 33 kurzgeschlossenen Schienen (vgl. Figur 1) oder auch in der Mitte des Kurzschlußverbinders 33 erfolgen. Bei den elektrischen Filtern 25 kann es sich um aus Kondensatoren und Spulen gebildete Serien- oder Parallelschwingkreise oder in einfachster Form um einen Kondensator mit C = 20 μF handeln; wesentlich ist bei diesen Filtern le- diglich, daß sie elektrisch in dem Frequenzbereich elektrisch niederohmig sind, den die Zugbeeinflussungseinrichtung 3 zum Datenaustausch zwischen Leitstelle 9 und den Schienenfahrzeugen 21 und 22 nutzt; dieser Frequenzbereich wird im weiteren als Nutzfrequenzbereich bezeichnet. Die Funktion der elektrischen Filter 25 besteht darin, die von den Schienenfahrzeugen 21 und 22 an die Schienen des Gleises 7 abgegebenen S orströme zur Erde 26 abzuleiten, so daß diese nicht über die Schienen von einem Gleissegment in das nächste Gleissegment gelangen können; unter Storströmen wird dabei der Anteil der von den Schienenfahrzeugen abgegebenen
5 Fahrströme verstanden, der im Nutzfrequenzbereich liegt. Konkret wird beispielsweise ein von dem einen Schienenfahrzeug 21 im Gleissegment 30 erzeugter und an die Schienen abgegebener Störstrom durch die elektrischen Filter 25 zur Erde 26 abgeleitet und von dort zum sogenannten Unterwerk zurückgeleitet; der Störstrom kann damit also weder in das Gleissegment 28 noch in das Gleissegment 32 gelangen, so daß eine Störung der Datenübertragung zwischen Leitstelle 9 und dem weiteren Schienenfahrzeug 22 weitgehend ausgeschlossen ist.FIG. 1 shows a train control device 3 for a track 7. The train control device 3 has a control center 9, which is connected via connecting lines 12 to track-side conductors 15 in the form of line conductors mounted in the track 7. The line conductors 15 have crossing points 18, which enable the rail vehicles located on the track 7 to be determined in a known manner. There are two electrically driven tracks 7 4 rail vehicles, namely a rail vehicle 21 and a further rail vehicle 22, each of which has antennas 23 with a receiving / transmitting unit 24. Data is transmitted between the train control device 3 and the rail vehicles 21 and 22 via the line conductors 15 and the antennas 23; The rail vehicles 21 and 22 are supplied with electrical drive energy via a contact wire, not shown, with which they are connected via contact elements. The two rail vehicles 21 and 22 are spatially separated from one another by electrical filters 25. The electrical filters 25 are each connected between earth 26 and the rails of the track 7 acting as return conductors and divide the track 7 into separate track segments 23, 30 and 32. The length of the track segments is determined by different factors, for example it can correspond to the average length of the rail vehicles. The electrical filters 25 can be connected directly to one of the two rails short-circuited by a short-circuit connector 33 (see FIG. 1) or in the middle of the short-circuit connector 33. The electrical filters 25 can be series or parallel resonant circuits formed from capacitors and coils or, in the simplest form, a capacitor with C = 20 μF; the only essential thing about these filters is that they are electrically low in the frequency range which the train control device 3 uses for data exchange between the control center 9 and the rail vehicles 21 and 22; this frequency range is referred to below as the useful frequency range. The function of the electrical filter 25 is to derive the or currents emitted by the rail vehicles 21 and 22 to the rails of the track 7 to the earth 26, so that they cannot get from one track segment to the next track segment; the proportion of those emitted by the rail vehicles is shown under Storstrom 5 understood driving currents, which is in the useful frequency range. Specifically, for example, an interference current generated by one rail vehicle 21 in the track segment 30 and delivered to the rails is discharged through the electrical filters 25 to the earth 26 and from there is returned to the so-called substation; the interference current can therefore neither get into the track segment 28 nor into the track segment 32, so that a disturbance in the data transmission between the control center 9 and the further rail vehicle 22 is largely excluded.
Bei der Zugbeeinflussungseinrichtung 3 gemäß Figur 1 ist der gleisseitige Leiter durch einen Linienleiter 15 gebildet; es ist selbstverständlich ebenfalls möglich, auf einen Linien- leiter zu verzichten und den gleisseitigen Leiter durch die Schienen zu bilden.1, the track-side conductor is formed by a line conductor 15; it is of course also possible to do without a line conductor and to form the track-side conductor through the rails.
Die erfindungsgemäße Zugbeeinflussungseinrichtung läßt sich darüber hinaus auch bei Gleisanlagen einsetzen, bei denen die Fahrströme der Schienenfahrzeuge über die Schienen als Rückleiter und/oder über separate Rückleiter abgeführt werden, die beispielsweise im Rahmen einer Oberleitung verlegt sein können. Eine derartige Gleisanlage zeigt schematisch Figur 2; dabei werden in Figur 2 für bereits im Zusammenhang mit der Figur 1 eingeführte Komponenten die gleichen Bezugszeichen verwendet wie in Figur 1. Man erkennt die separaten Rückleiter 50, die Erde 26 und ein zwischen die Erde 26 und die separaten Rückleiter 50 sowie die Schienen des Gleises geschaltetes elektrisches Filter 25. Die Schienen sind durch einen Kurzschlußverbinder 33 kurzgeschlossen.
The train control device according to the invention can also be used in track systems in which the travel currents of the rail vehicles are discharged via the rails as return conductors and / or via separate return conductors, which can be laid, for example, in the context of an overhead line. Such a track system is shown schematically in FIG. 2; the same reference numerals are used in FIG. 2 for components already introduced in connection with FIG. 1 as in FIG. 1. The separate return conductors 50, the earth 26 and one between the earth 26 and the separate return conductors 50 and the rails of the track can be seen switched electrical filter 25. The rails are short-circuited by a short-circuit connector 33.
