Definitions
- the present invention relates to a method and a device for detecting a short circuit and/or interruption of an electrical connection for the transmission of data telegrams between a control unit arranged on the track side that controls and/or monitors a balise and the balise arranged on the track side.
- ETCS telegrams i.e. information about the travel authorization (Movement Authority MA), the range of this MA (End of Authority EoA), specified braking curves, etc., are used. transmitted wirelessly to the control unit of a rail vehicle (onboard unit OBU) via so-called ETCS balises.
- a 27 MHz telepowering signal is sent out from the Switzerlandspitze, which induces an amount of energy into the balise that is sufficient to trigger the transmission and to actually send out the ETCS telegrams.
- the present invention is therefore based on the object of providing a method and a device for detecting a short circuit and/or interruption of an electrical connection for the transmission of data telegrams between a control unit arranged on the track side that controls and/or monitors a balise and the balise arranged on the track side make it easy to reliably identify cable breaks, short circuits and missing balises.
- the occurrence of a cable break, a short circuit and/or the determination of the absence of the balise can be reliably detected and reported using the method. Due to the inductive decoupling of the current signal, the data transmission can be observed virtually without any reaction to the transmitted data.
- the current sensor can be provided as a folding throttle.
- This folding choke for example in the form of a ferrite choke, can be easily attached to the existing connecting cable and provides a sufficiently large voltage signal for the evaluation circuit.
- the scanning can be carried out on the C interface between the control unit and the balise as part of a transmission of data telegrams according to the ETCS standard.
- the current sensor, the evaluation circuit and the means for providing the warning information can be integrated into the control unit in a particularly simple manner in terms of assembly technology. This means that the supply of an electrical supply voltage, e.g. 24 VDC, can be solved in a particularly simple manner as a “parasitic consumer” next to the control unit that is actually supplied.

- the control unit 8 supplies the device 2 with electrical power in the form of a 24 V DC supply 10.
- a current sensor designed as a ferrite choke 12 inductively detects data transmission on the electrical connection 4, which is referred to as a C-interface in the context of the ETCS .
- the voltage U C induced in the ferrite choke 12 is first monitored by an evaluation circuit 14 by a limit detector 16 for the induced voltage to ensure that a predefined voltage limit value and/or a predefined voltage pattern is exceeded. If an exceedance occurs, the induced voltage signal U C is subjected to a further test, which is represented here by a short-circuit detection 18 and a cable break detection 20. In the present case, reference voltages 22 are also made available for these further checks.

- the present exemplary embodiment shows a possibility for error disclosure for an electrical connection 4 and a balise 6.
- the device 2 is appropriately equipped with an FPGA or a microcontroller, other connections and further balises can also be examined for errors, especially since in the In practice, a balise point on a two-lane route usually often includes four to eight balises.

Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Einrichtung zur Detektion eines Kurzschlusses und/oder Unterbruchs einer elektrischen Verbindung zur Übertragung von Datentelegrammen zwischen einer eine Balise steuernden und/oder überwachenden gleisseitig angeordneten Steuereinheit und der gleisseitig angeordneten Balise.The present invention relates to a method and a device for detecting a short circuit and/or interruption of an electrical connection for the transmission of data telegrams between a control unit arranged on the track side that controls and/or monitors a balise and the balise arranged on the track side.
In nach dem Standard «European Train Controll System ETCS» arbeitenden Zugsicherungs- und -beeinflussungssystem werden sogenannte ETCS-Telegramme, d.h. Informationen zur Fahrtberechtigung (Movement Authority MA), zur Reichweite dieser MA (End of Authority EoA), zu vorgegebenen Bremskurven etc., über sogenannten ETCS-Balisen drahtlos auf die Steuerungseinheit eines Schienenfahrzeugs (Onboard Unit OBU) übertragen. Dabei wird von der Zugspitze ein 27 MHz Telepowering-Signal ausgesendet, dass in die Balise eine Energiemenge induziert, die zum Triggern der Aussendung und zur tatsächlichen Aussendung der ETCS-Telegramme ausreichend ist.In the train control and control system that works according to the “European Train Control System ETCS” standard, so-called ETCS telegrams, i.e. information about the travel authorization (Movement Authority MA), the range of this MA (End of Authority EoA), specified braking curves, etc., are used. transmitted wirelessly to the control unit of a rail vehicle (onboard unit OBU) via so-called ETCS balises. A 27 MHz telepowering signal is sent out from the Zugspitze, which induces an amount of energy into the balise that is sufficient to trigger the transmission and to actually send out the ETCS telegrams.
Leider kommt es aufgrund von herabhängenden Gegenständen und/oder Vandalismus immer wieder vor, dass die elektrische Verbindungsleitung zur Balise beschädigt wird und beispielsweise einen Erdschluss aufweist oder sogar ganz von der Balise getrennt wird. Auch der Diebstahl einzelner Balisen wurde leider schon beobachtet.Unfortunately, due to hanging objects and/or vandalism, it often happens that the electrical connection cable to the balise is damaged and, for example, has a ground fault or is even completely disconnected from the balise. Unfortunately, the theft of individual balises has also been observed.
Diese Fehler können derzeit nur aufgedeckt werden, wenn auf dem Fahrzeugrechner (OBU = Onboard Unit) das Ausbleiben eines eigentlich zu empfangenden Balisentelegramms bemerkt wird. Dies würde aber voraussetzen, dass die OBU die genauen Balisenstandorte und die genaue Zugposition kennen müsste. Gerade die Balisen helfen aber der OBU bei der genauen Ortung des Aufenthaltungsortes des Schienenfahrzeugs/Zuges. Daher ist dieser Weg der Fehleroffenbarung selbst sehr fehlerbehaftet oder steht insgesamt nicht wirklich belastbar zur Verfügung.These errors can currently only be detected if the vehicle computer (OBU = Onboard Unit) notices that a balise telegram is not actually being received. However, this would require that the OBU would have to know the exact balise locations and the exact train position. The balises in particular help the OBU to precisely locate the location of the rail vehicle/train. thats why This path of error disclosure itself is very error-prone or is not really available in a reliable manner overall.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Einrichtung zur Detektion eines Kurzschlusses und/oder Unterbruchs einer elektrischen Verbindung zur Übertragung von Datentelegrammen zwischen einer eine Balise steuernden und/oder überwachenden gleisseitig angeordneten Steuereinheit und der gleisseitig angeordneten Balise zugeben, die es auf einfache Weise ermöglichen, Kabelunterbrüche, Kurzschlüsse sowie fehlende Balisen sicher zu identifizieren.The present invention is therefore based on the object of providing a method and a device for detecting a short circuit and/or interruption of an electrical connection for the transmission of data telegrams between a control unit arranged on the track side that controls and/or monitors a balise and the balise arranged on the track side make it easy to reliably identify cable breaks, short circuits and missing balises.
Diese Aufgabe wird erfindungsgemäss durch ein Verfahren zur Detektion eines Kurzschlusses und/oder Unterbruchs einer elektrischen Verbindung zur Übertragung von Datentelegrammen zwischen einer eine Balise steuernden und/oder überwachenden gleisseitig angeordneten Steuereinheit und der gleisseitig angeordneten Balise gelöst, welches die folgenden Verfahrensschritte umfasst:
- a) rückwirkungsfreies Abtasten der Datenübertragung mittels eines induktiv wirkenden Stromsensors;
- b) Auswerten des in dem Stromsensor induzierten Spannungssignale in einem Auswertekreis, indem das Spannungssignal mit vorbestimmten Signalmustern und/oder Spannungsgrenzwerten verglichen wird, und
- c) Bereitstellen einer Warnungsinformation bei Feststellung einer zu grossen Abweichung des Spannungssignals von den vorbestimmten Signalmustern und/oder den Spannungsgrenzwerten.
- a) reaction-free sampling of the data transmission using an inductive current sensor;
- b) evaluating the voltage signals induced in the current sensor in an evaluation circuit by comparing the voltage signal with predetermined signal patterns and/or voltage limit values, and
- c) Providing warning information if the voltage signal deviates too much from the predetermined signal patterns and/or the voltage limit values.
Auf diese Weise kann mittels des Verfahrens das Auftreten eines Kabelunterbruchs, eines Kurzschlusses und/oder die Feststellung des Fehlens der Balise sicher detektiert und gemeldet werden. Aufgrund der induktiven Auskopplung des Stromsignals kann die Datenübertragung quasi rückwirkungsfrei für die übertragenen Daten beobachtet werden.In this way, the occurrence of a cable break, a short circuit and/or the determination of the absence of the balise can be reliably detected and reported using the method. Due to the inductive decoupling of the current signal, the data transmission can be observed virtually without any reaction to the transmitted data.
In einer vorteilhaften Ausgestaltung der vorliegenden Erfindung kann der Stromsensor als Klappdrossel bereitgestellt werden. Diese Klappdrossel, beispielsweise in Form einer Ferrit-Drossel, kann sehr einfach an dem bestehenden Verbindungskabel befestigt werden und liefert ein hinreichend grosses Spannungssignal für den Auswertekreis.In an advantageous embodiment of the present invention, the current sensor can be provided as a folding throttle. This folding choke, for example in the form of a ferrite choke, can be easily attached to the existing connecting cable and provides a sufficiently large voltage signal for the evaluation circuit.
In einer zweckmässigen Ausgestaltung der vorliegenden Erfindung kann im Rahmen einer Übertragung von Datentelegrammen nach ETCS-Standard die Abtastung auf dem C-Interface zwischen Steuereinheit und Balise durchgeführt werden.In an expedient embodiment of the present invention, the scanning can be carried out on the C interface between the control unit and the balise as part of a transmission of data telegrams according to the ETCS standard.
In montagetechnisch besonders einfacher Weise können der Stromsensor, der Auswertekreis und die Mittel zum Bereitstellen der Warnungsinformation in die Steuereinheit integriert sein. Damit kann auch die Zuführung einer elektrischen Versorgungsspannung, z.B. 24 VDC, in besonders einfacher Weise quasi als «parasitärer Verbraucher» neben der eigentlich versorgten Steuereinheit gelöst werden.The current sensor, the evaluation circuit and the means for providing the warning information can be integrated into the control unit in a particularly simple manner in terms of assembly technology. This means that the supply of an electrical supply voltage, e.g. 24 VDC, can be solved in a particularly simple manner as a “parasitic consumer” next to the control unit that is actually supplied.
In einer vorteilhaften Ausgestaltung der vorliegenden Erfindung kann die Warnungsinformation optisch an der Steuereinheit angezeigt und/oder über eine Funkschnittstelle an eine Wartungszentrale übertragen werden.In an advantageous embodiment of the present invention, the warning information can be displayed optically on the control unit and/or transmitted to a maintenance center via a radio interface.
Entsprechende Merkmale der vorliegenden Erfindung können bezüglich der Einrichtung den anhängenden Patentansprüchen 6 bis 10 entnommen werden.Corresponding features of the present invention can be found in the appended claims 6 to 10 with regard to the device.
Bevorzugte Ausführungsbeispiele der vorliegenden Erfindung werden nachfolgend mit Bezug auf eine Zeichnung näher erläutert. Dabei zeigt die Figur eine Einrichtung 2 zur Detektion eines Kurzschlusses und/oder Unterbruchs einer elektrischen Verbindung 4 zur Übertragung von Datentelegrammen zwischen einer eine Balise 6 steuernden und/oder überwachenden gleisseitig angeordneten Steuereinheit 8 und der gleisseitig angeordneten Balise 6. Die elektrische Verbindung 4 betrifft dabei hier vorliegend die Signalleitung zur Übertragung von Datentelegrammen nach ETCS-Standard auf dem sogenannten C-Interface zwischen der Steuereinheit 8 und der Balise 6.Preferred exemplary embodiments of the present invention are explained in more detail below with reference to a drawing. The figure shows a
Die Steuereinheit 8 versorgt die Einrichtung 2 mit elektrischer Leistung in Form einer 24 V DC-Speisung 10. Ein als Ferrit-Drossel 12 ausgeführter Stromsensor erfasst dabei induktiv eine Datenübertragung auf der elektrischen Verbindung 4, die im Rahmen des ETCS als C-Interface bezeichnet wird. Die in der Ferrit-Drossel 12 induzierte Spannung UC wird von einem Auswertekreis 14 zunächst von einem Grenzwertdetektor 16 für die induzierte Spannung auf die Überschreitung von einem vordefinierten Spannungsgrenzwert und/oder einem vordefinierten Spannungsmuster überwacht. Kommt zu einer Überschreitung wird das induzierte Spannungssignal UC einer weiteren Prüfung unterzogen, was hier durch ein Kurzschlussdetektion 18 und eine Kabelunterbruchsdetektion 20 repräsentiert ist. Vorliegend werden für diese weiteren Überprüfungen auch Referenzspannungen 22 zur Verfügung gestellt.The control unit 8 supplies the
Die Ergebnisse der weiteren Prüfung in der Kurzschlussdetektion 18 und Kabelunterbruchsdetektion 20 werden einem Warnmodul 24 zugeführt, welches Warninformationen (Kurzschluss 26, Kabel(unter)bruch 28) zur Behebung des detektierten Schadens für eine Leitzentrale und/oder eine Instandhaltungsgruppe bereitstellt. Diese Warninformation kann zusätzlich beispielsweise an der Einrichtung 2 direkt in Form einer optischen Anzeige mittels LED jeweils für den Fehler des Kurzschlusses und des Kabel(unter)bruchs signalisiert werden.The results of the further test in the
Für die Übertragung der Warninformation an die Leitzentrale und/oder die Instandhaltungsgruppe können verschiedene Wege vorgesehen sein. Einerseits kann der Datenkanal zwischen der Steuereinheit 8 und einem hier nicht weiter dargestellten Stellwerk/RBC in Rückübertragungsrichtung genutzt werden.Various ways can be provided for transmitting the warning information to the control center and/or the maintenance group. On the one hand, the data channel between the control unit 8 and an interlocking/RBC (not shown here) can be used in the retransmission direction.
Andererseits ist es aber auch möglich, die Einrichtung mit einem entsprechenden Funkmodul, z.B. GSM-R, auszustatten und die Warninformation drahtlos auszusenden.On the other hand, it is also possible to equip the device with a corresponding radio module, e.g. GSM-R, and send the warning information wirelessly.
Obwohl die Einrichtung 2 in der gezeigten Darstellung als separater Block abseits der Steuereinheit 8 dargestellt ist, können sämtliche Komponenten und Funktionalitäten der Einrichtung 2 auch direkt in die Steuereinheit integriert sein, was u.a. auch die Versorgung der Einrichtung mit elektrischer Leistung stark vereinfacht, da die Steuereinheit 8 in der Regel über eine Speiseleitung verfügt.Although the
Die Einrichtung 2 stellt damit eine einfach in der Bahnumgebung nachrüstbare Möglichkeit zur Fehleroffenbarung dar. Durch den Einsatz der Ferrit-Drossel 12 in Form einer Klappdrossel muss auch keine Leitung aufgetrennt werden, sodass kein Eingriff in ein laufendes und approbiertes System/Verfahren zur Zuglenkung/- steuerung erforderlich wird.The
Das vorliegende Ausführungsbeispiel zeigt hier eine Möglichkeit zur Fehleroffenbarung für eine elektrische Verbindung 4 und eine Balise 6. Selbstverständlich können bei entsprechender Ausrüstung der Einrichtung 2 mit einem FPGA oder einem Micro-Controller auch weitere Verbindungen und weitere Balisen auf Fehler hin untersucht werden, zumal in der Praxis ein Balisenpunkt bei einer zweispurigen Strecke in der Regel oft vier bis acht Balisen umfasst. Auch die Mittel zur Übertragung der Warninformation können dann gemeinsam genutzt werden.The present exemplary embodiment shows a possibility for error disclosure for an
