Description

Hintergrund der ErfindungBackground of the invention

Die Erfindung betrifft eine Balise für eine Zugbeeinflussungsvorrichtung mit einer Empfangseinrichtung zum Empfangen eines Transpondersignals, einen Signalgenerator zum Erzeugen von Datentelegrammen, einer Sendeeinrichtung zum Versenden der Datentelegramme, und einem ersten Speicherbaustein mit einem gespeicherten Störungstelegramm. Die Erfindung betrifft auch ein Zugsicherungssystem mit einer solchen Balise.The invention relates to a balise for a train control device with a receiving device for receiving a transponder signal, a signal generator for generating data telegrams, a transmitting device for sending the data telegrams, and a first memory device with a stored disturbance telegram. The invention also relates to a train protection system with such a balise.

Eine derartige Balise ist bekannt aus EP 2 406 117 B1 .Such a balise is known from EP 2 406 117 B1 ,

Balisen dienen zum Übertragen von bahnbetrieblichen Informationen (z.B. Schaltungszustände von Streckensignalen, Belegungszustände von Gleisabschnitten, Geschwindigkeitsbegrenzungen usw.) an Schienenfahrzeuge, die den Ort der Balise passieren. In der Balise ist ein Störungstelegramm (Default-Telegramm) gespeichert. Das Störungstelegramm wird durch den Signalgenerator der Balise erzeugt. Es wird versendet, wenn die Zugbeeinflussungsvorrichtung eine Störung erkennt.Balis are used to transmit railway information (e.g., circuit statuses of line signals, track section occupancy conditions, speed limits, etc.) to rail vehicles passing through the location of the balise. A fault telegram (default telegram) is stored in the balise. The fault telegram is generated by the signal generator of the balise. It is sent when the train control device detects a fault.

Aufgrund von europäischen Vorgaben werden Eurobalisen (Transparentdatenbalise) mit einer streckenseitigen elektronischen Einheit (LEU) verwendet. Die streckenseitige elektronische Einheit versorgt die Balise über eine serielle Schnittstelle ständig mit den zu sendenden Telegrammen. Dazu greift die streckenseitige elektronische Einheit Informationen des Stellwerks ab und generiert daraus ein Telegramm, welches über die Schnittstelle an die Balise übertragen und von dieser an das Fahrzeug, welches die Balise passiert, gesendet wird. Die Balise fungiert also lediglich als Sendeantenne. Dabei wird die Balise selbst durch die Antenne des Fahrzeugs mit Energie versorgt. Die streckenseitige elektronische Einheit muss jedoch über eine zusätzliche externe Stromquelle mit Energie versorgt werden. Dies ist ein wesentlicher Kostenfaktor, da nicht überall freie Leitungen zur Energieversorgung vorhanden sind.Due to European specifications Eurobalises (transparent data balise) are used with a trackside electronic unit (LEU). The track-side electronic unit constantly supplies the balise with the telegrams to be sent via a serial interface. For this purpose, the track-side electronic unit uses information from the interlocking and generates a telegram, which is transmitted via the interface to the balise and sent by the latter to the vehicle that passes through the balise. So the balise acts only as a transmitting antenna. The Balise itself is powered by the antenna of the vehicle with energy. However, the trackside electronic unit must be powered by an additional external power source. This is a significant cost factor, as not everywhere free lines for energy supply are available.

Um den Energiebedarf der streckenseitigen elektronischen Einheit zu reduzieren, schlägt die EP 2 406 117 B1 eine Zugbeeinflussungseinrichtung vor, bei der die Telegramme nicht kontinuierlich, sondern nur während des Empfangs eines Aktivierungssignals (bei Annäherung des Zuges) an die Balise gesendet werden.To reduce the energy consumption of the trackside electronic unit, proposes the EP 2 406 117 B1 a Zugbeeinflussungseinrichtung ago, in which the telegrams are not continuously, but only during the reception of an activation signal (when approaching the train) are sent to the Balise.

Aufgabe der ErfindungObject of the invention

Es ist Aufgabe der Erfindung, eine Balise und ein Zugsicherungssystem vorzuschlagen, das auf eine externe Stromversorgung verzichten kann.It is an object of the invention to provide a balise and a train protection system that can dispense with an external power supply.

Beschreibung der ErfindungDescription of the invention

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Balise gemäß Patentanspruch 1 und einem Zugsicherungssystem gemäß Patentanspruch 8.This object is achieved by a balise according to claim 1 and a train protection system according to claim 8.

Erfindungsgemäß sind in der Balise mindestens ein weiterer Speicherbaustein und eine digitale Schnittstelle zum Verbinden des weiteren Speicherbausteins mit einer Schalteinheit mit mindestens einem Schaltkontakt vorgesehen.According to the invention, at least one further memory module and a digital interface for connecting the further memory module to a switching unit having at least one switching contact are provided in the balise.

Die weiteren Speicherbausteine dienen zur Speicherung von weiteren Telegrammen. Die erfindungsgemäße Balise kann also neben dem Störungstelegramm noch weitere Telegramme speichern. Bei den weiteren Telegrammen handelt es sich vorzugsweise um Fahrttelegramme, also um Telegramme, die darüber informieren, dass und gegebenenfalls mit welcher Geschwindigkeit der Telegrammempfänger fahren darf. Vorzugsweise ist in den weiteren Speicherbausteinen je ein Telegramm gespeichert. Die weiteren Telegramme können (wie auch das Störungstelegramm) innerhalb der Balise durch den Signalgenerator generiert werden. Es ist jedoch auch möglich, dass die weiteren Telegramme extern, z.B. von einer streckenseitigen elektronischen Einheit generiert und an die Balise gesendet werden.The other memory blocks are used to store further telegrams. The balise according to the invention can therefore store further telegrams in addition to the disturbance telegram. The further telegrams are preferably travel telegrams, that is to say telegrams which inform that, and where appropriate, at which speed the telegram receiver is allowed to travel. Preferably, one telegram is stored in each of the further memory modules. The other telegrams (as well as the fault telegram) can be generated within the balise by the signal generator. However, it is also possible that the further telegrams are externally, e.g. generated by a trackside electronic unit and sent to the balise.

Das Übertragen der Telegramme an das passierende Fahrzeug erfolgt durch die Sendeeinheit. Die Energieversorgung der Sendeeinrichtung erfolgt vorzugsweise direkt innerhalb der Balise durch das aufgrund eines passierenden Fahrzeugs in der Empfangseinheit induzierte Transpondersignal. Durch die Energieversorgung der Sendeeinrichtung innerhalb der Balise ist sichergestellt, dass das Störungstelegramm auch bei einem Kabelbruch gesendet werden kann.The transmission of the telegrams to the passing vehicle is carried out by the transmitting unit. The energy supply of the transmitting device is preferably carried out directly within the balise by the transponder signal induced in the receiving unit due to a passing vehicle. The power supply of the transmitting device within the balise ensures that the fault telegram can also be sent in the event of a cable break.

Da bei der erfindungsgemäßen Balise die Datentelegramme direkt in der Balise gespeichert werden können, kann das Erzeugen eines seriellen Datenstroms durch eine streckenseitige elektronische Einheit entfallen. Dadurch kann auf die Stromversorgung für die streckenseitige elektronische Einheit verzichtet werden.Since the data telegrams can be stored directly in the balise in the balise invention, the generation of a serial data stream can be omitted by a trackside electronic unit. As a result, can be dispensed with the power supply for the trackside electronic unit.

Bei einer bevorzugten Ausführungsform sind mehrere, vorzugsweise mindestens drei, weitere voneinander unabhängige Speicherbausteine vorgesehen. Unter "unabhängige Speicherbausteine" sind Bauelemente mit separater Stromzuführung und entkoppelten Anschlüssen zur Sendevorrichtung zu verstehen, so dass keine Beeinflussung eines Speicherbausteins durch einen anderen Speicherbaustein oder anderen Teil der Schaltung erfolgt (physikalische Unabhängigkeit). Durch das Vorsehen von mehreren unabhängigen Speicherbausteinen können gegebenenfalls auch Schaltzustände mehrerer Zusatzanzeiger und Geschwindigkeitsanzeiger über die Balise übertragen werden.In a preferred embodiment, several, preferably at least three, further independent memory modules are provided. "Independent memory chips" are components with separate power supply and decoupled connections to the transmitting device to understand, so that no influence of a memory device by another memory device or other part of the circuit takes place (physical independence). By providing a plurality of independent memory modules, switching states of a plurality of additional indicators and speed indicators can optionally also be transmitted via the balises.

Vorzugsweise ist mindestens einer der weiteren Speicherbausteine programmierbar. Auf diese Weise können bei Bedarf die Telegramme in den Speicherbausteinen ausgetauscht werden.Preferably, at least one of the further memory modules is programmable. In this way, if required, the telegrams can be exchanged in the memory modules.

Bei einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Balise ist die digitale Schnittstelle zur Verbindung der Empfangseinrichtung und des mindestens einen weiteren Speicherbausteins mit der Schalteinheit eingerichtet. Auf diese Weise kann über die Schalteinheit eine autarke Stromversorgung für den mindestens einen Speicherbaustein realisiert werden. Dazu wird der in der Empfangseinrichtung induzierte Strom über die Schnittstelle zur Schalteinheit und von dort über die Schnittstelle zu einem der Speicherbausteine geleitet. Die Speicherbausteine können also über die Schnittstelle mit Strom versorgt werden, wenn in der Empfangseinrichtung Strom/Spannung (durch einen darüberfahrendes Fahrzeug) induziert wird. Alternativ können anstelle der Versorgung der Speicherbausteine selbst nur die Ausgangstreiber der Speicherbausteine mit Strom /Spannung über die Schnittstelle versorgt werden. Dies hat den Vorteil, dass ein schnelleres Ansprechverhalten bei Telegrammwechsel realisiert werden kann, da die Verzögerungszeit beim Anschalten des Speicherbausteins entfällt.In a particularly preferred embodiment of the balise invention, the digital interface for connecting the receiving device and the at least one further memory module is set up with the switching unit. In this way, a self-sufficient power supply for the at least one memory module can be realized via the switching unit. For this purpose, the current induced in the receiving device is conducted via the interface to the switching unit and from there via the interface to one of the memory modules. The memory modules can therefore be supplied with power via the interface if current / voltage is induced in the receiving device (by a vehicle passing over it). Alternatively, instead of supplying the memory modules themselves, only the output drivers of the memory modules can be supplied with current / voltage via the interface. This has the advantage that a faster response can be realized at telegram change, since the delay time when turning on the memory module is omitted.

Vorzugsweise weist die digitale Schnittstelle für jeden Speicherbaustein eine separate Ader im Anschluss auf. Die einzelnen Speicherbausteine können so unabhängig voneinander über die digitale Schnittstelle mit Strom versorgt werden. Vorzugsweise ist jedem Schaltkontakt ein Telegramm zugeordnet, das versendet werden soll, wenn der jeweilige Schaltkontakt geschlossen ist. Durch das Vorsehen von separaten Anschlüssen für die unterschiedlichen Speicherbausteine kann sichergestellt werden, dass nur dasjenige Telegramm versendet wird, welches in dem Speicherbaustein abgespeichert ist, der über die entsprechende Ader mit dem geschlossenen Schaltkontakt verbunden ist.The digital interface preferably has a separate core for each memory module. The individual memory modules can be supplied with power independently of each other via the digital interface become. Each switching contact is preferably assigned a telegram which is to be sent when the respective switching contact is closed. By providing separate terminals for the different memory modules can be ensured that only that telegram is sent, which is stored in the memory module, which is connected via the corresponding wire to the closed switch contact.

Die erfindungsgemäße Balise kann eine weitere digitale Schnittstelle zum Empfangen von Datentelegrammen von einer streckenseitigen elektronischen Einheit aufweisen. Die Balise entspricht somit den Anforderungen einer Eurobalise und kann auch in ETCS-Systemen (European Train Control System), d.h. als Transparentbalise verwendet werden.The balise according to the invention can have a further digital interface for receiving data telegrams from a trackside electronic unit. The balise thus meets the requirements of a Eurobalise and can also be used in ETCS systems (European Train Control System), i. be used as a transparent balise.

Vorzugsweise sind die weiteren Speicherbausteine mit dem ersten Speicherbaustein elektrisch verbunden. Auf diese Weise kann das Senden des Störungstelegramms deaktiviert werden, sobald einer der weiteren Speicherbausteine aktiv ist und von ihm ein Telegramm gesendet wird.Preferably, the further memory modules are electrically connected to the first memory module. In this way, the transmission of the fault telegram can be deactivated as soon as one of the further memory modules is active and a telegram is sent from it.

Das erfindungsgemäße Zugsicherungssystem umfasst mindestens eine zuvor beschriebene Balise zur streckenseitigen Montage und ist dadurch gekennzeichnet, dass die weiteren Speicherbausteine der Balise jeweils mit mindestens einem Schaltkontakt der Schalteinheit über die Schnittstelle verbunden ist.The train protection system according to the invention comprises at least one previously described balise for track-side mounting and is characterized in that the further memory components of the balise is respectively connected to at least one switching contact of the switching unit via the interface.

Eine Fahrtfreigabe erfolgt durch Aussenden des in dem entsprechenden Speicherbaustein gespeicherten Telegramms durch die Sendeeinheit der Balise nur, wenn der entsprechende Speicherbaustein mit Energie versorgt wird. Ohne diese Energiezuführung können keine Fahrttelegramme gesendet werden. Ausschließlich das Störungstelegramm mit einem "restriktiven" Begriff wird bei Ausfall oder Fehlfunktion der Schalteinheit gesendet. Alternativ können im Störungstelegramm auch die Telegramminformationen für die Signalbegriffe "Halt erwartet" oder "Halt" enthalten sein. Indem die Zustände "Halt" bzw. "Halt erwartet" und eine Störung der Anlage von ihrer Wirkung auf den Zug gleichgesetzt werden und in einem gemeinsamen Telegramm (Störungstelegramm) kodiert werden, kann die Anzahl der Speicherbausteine reduziert werden, bzw. es können mehr Signalbegriffe in einer Balise kodiert werden.A drive release takes place by sending out the telegram stored in the corresponding memory module by the transmitting unit of the balise only if the corresponding memory module is supplied with energy. Without this energy supply no travel telegrams can be sent. Only the fault telegram with a "restrictive" term is sent in the event of a failure or malfunction of the switching unit. Alternatively, the telegram information for the signal terms "stop expected" or "stop" can also be contained in the fault telegram. By equating the states "Halt" and "Halt expected" and a malfunction of the system from its effect on the train and in a common telegram (Fault telegram) are encoded, the number of memory modules can be reduced, or it can be coded more signal terms in a balise.

Je nach Anzahl der in der Balise vorgesehenen Speicherbausteine und der Anzahl an zu versendenden Telegrammen können auch mehrere Balisen zum Einsatz kommen. Die verschiedenen Balisen sind vorzugsweise mit unterschiedlichen Schaltkontakten derselben Schalteinheit verbunden. Wenn bei zwei Signalbegriffen das gleiche Telegramm gesendet werden soll, können auch zwei Schaltkontakte am gleichen Speicherbaustein parallel verwendet werden. Die Stromversorgung des entsprechenden Speicherbausteins erfolgt dann, wenn mindestens einer der mit diesem Speicherbaustein verbundenen Schaltkontakte geschlossen ist. Darüber hinaus können auch redundante Balisen vorgesehen sein, also mehrere Balisen, in deren Speicherbausteine die gleichen Telegramme gespeichert sind, wobei die Balisen mit denselben (oder redundanten) Schaltkontakten verbunden sind. Auf diese Weise kann die Ausfallsicherheit erhöht werden. Insbesondere kann als Schalteinheit ein Schaltkasten zur punktuellen Zugbeeinflussung (PZB-Schaltkasten) verwendet werden. Bei Verwendung von Balisengruppen mit mindestens zwei Balisen kann eine der Balisen als Festdatenbalise (Balise, die einmalig bei der Installation programmiert wird) ausgelegt sein.Depending on the number of memory blocks provided in the balise and the number of telegrams to be sent, several balises can also be used. The various balises are preferably connected to different switching contacts of the same switching unit. If the same telegram is to be sent with two signal terms, two switch contacts on the same memory block can also be used in parallel. The power supply of the corresponding memory module takes place when at least one of the switching contacts connected to this memory module is closed. In addition, it is also possible to provide redundant balises, ie several balises in whose memory blocks the same telegrams are stored, the balises being connected to the same (or redundant) switching contacts. In this way, the reliability can be increased. In particular, can be used as a switching unit, a switch box for selective train control (PZB control box). When using balise groups with at least two balises, one of the balises can be designed as a fixed data balise (balise, which is programmed once during installation).

Bei einer besonders bevorzugten Ausführungsform ist die Schalteinheit mit der Empfangseinrichtung elektrisch verbunden. Somit kann eine von der Schalteinheit gesteuerte Energieversorgung der weiteren Speicherbausteine von der Empfangseinrichtung über die digitale Schnittstelle erfolgen.In a particularly preferred embodiment, the switching unit is electrically connected to the receiving device. Thus, a power supply of the further memory modules controlled by the switching unit can be effected by the receiving device via the digital interface.

Vorzugsweise entspricht die Anzahl der weiteren Speicherbausteine der Anzahl der Schaltkontakte in der Schalteinheit.Preferably, the number of further memory modules corresponds to the number of switching contacts in the switching unit.

Die Schalteinheit ist vorzugsweise Teil eines Signalschaltkreises oder mit einem Signalschaltkreis gekoppelt. Die Schalteinheit kann also Schaltkontakte des Signalschaltkreises umfassen. Diese Variante ist besonders wenig fehleranfällig, da keine weiteren Komponenten zwischen Schaltkontakt des Signals und Speicherbaustein geschaltet sind. Alternativ hierzu kann die Schalteinheit mit dem Signalschaltkreis, bspw. über einen Transformator, gekoppelt sein. Letzteres ist insbesondere dann relevant, wenn am Streckensignal keine Schaltkontakte vorhanden sind. In diesem Fall können als Schalteinheit z.B. ein bereits zugelassener PZB(punktförmige Zugbeeinflussung)-Schaltkasten dienen. Dieser kann aufgrund seiner sehr geringen Energieaufnahme aus dem Signalschaltkreis versorgt werden. Zur Ansteuerung der Balise kann im Prinzip jeder Schaltkontakt verwendet werden, insbesondere Relais oder C-MOS-Schalter.The switching unit is preferably part of a signal circuit or coupled to a signal circuit. The switching unit may thus comprise switching contacts of the signal circuit. This variant is particularly error-prone, since no other components between switching contact of the signal and memory module are connected. Alternatively, the Switching unit with the signal circuit, for example. Be coupled via a transformer. The latter is particularly relevant if there are no switching contacts on the route signal. In this case, the switching unit can be, for example, an already approved PZB (punctiform train control) switch box. This can be supplied from the signal circuit due to its very low power consumption. For controlling the balise, in principle any switching contact can be used, in particular relays or C-MOS switches.

Detaillierte Beschreibung der Erfindung und ZeichnungDetailed description of the invention and drawing

Fig. 1Fig. 1
zeigt ein erfindungsgemäßes Zugsicherungssystem.shows an inventive train protection system.

Fig. 1 zeigt ein erfindungsgemäßes Zugsicherungssystem mit einer Balise 1, die eine Empfangseinrichtung 2 zum Empfangen von Transpondersignalen von passierenden Fahrzeugen und eine Sendeeinrichtung 3 zum Senden von Datentelegrammen aufweist. In einem ersten Speicherbaustein 4 der Balise 1 ist ein Störungstelegramm gespeichert. Erfindungsgemäß sind weitere, voneinander unabhängige und vorzugsweise programmierbare Speicherbausteine 5 in der Balise 1 vorgesehen, in denen zu sendende (weitere) Telegramme gespeichert sind. Die weiteren Speicherbausteine 5 (bzw. deren Treiber) erhalten ihre Versorgungsspannung über eine digitale Schnittstelle 6, die mit einer Schalteinheit 7 mit Schaltkontakten 8 elektrisch verbunden ist. Die Schalteinheit 7 verbindet über die digitale Schnittstelle 6 die weiteren Speicherbausteine 5 mit der Empfangseinrichtung 2, die für die Stromversorgung der Speicherbausteine 5 verantwortlich ist. Die Schalteinheit 7 kann Teil eines Signalschaltkreises des Streckensignals sein. Sind am Streckensignal keine Schaltkontakte vorhanden, so können diese durch einen schon zugelassenen PZB-Schaltkasten geliefert werden. Dieser kann aufgrund seiner sehr geringen Energieaufnahme aus dem Lampenstromkreis versorgt werden. Die Versorgung der weiteren Speicherbausteine 5 mit Strom/Spannung erfolgt nur dann, wenn der zugehörige Schaltkontakt 8 in der Schalteinheit 7 geschlossen ist, d.h. nur wenn ein passierendes Fahrzeug Energie einspeist und ein Schaltkontakt 8 am Streckensignal geschlossen ist, kann die Balise 1 das entsprechende Telegramm an das Fahrzeug senden. Je nachdem welcher Schaltkontakt 8 der Schalteinheit 7 geschlossen ist, werden unterschiedliche Speicherbausteine 5 mit Strom versorgt. Die Balise 1 kann dann das entsprechende Telegramm an das passierende Fahrzeug senden. Welches Telegramm gesendet wird, wird gemäß der Erfindung also durch externe Kontakte (Schaltkontakte 8 der Schalteinheit 7) ausgewählt. 1 shows an inventive train protection system with a balise 1, which has a receiving device 2 for receiving transponder signals from passing vehicles and a transmitting device 3 for transmitting data telegrams. A disturbance telegram is stored in a first memory module 4 of the balise 1. According to the invention, further, independent and preferably programmable memory modules 5 are provided in the balise 1, in which to be sent (more) telegrams are stored. The further memory modules 5 (or their drivers) receive their supply voltage via a digital interface 6, which is electrically connected to a switching unit 7 with switching contacts 8 . The switching unit 7 connects via the digital interface 6, the other memory modules 5 with the receiving device 2, which is responsible for the power supply of the memory modules 5. The switching unit 7 may be part of a signal circuit of the path signal. If there are no switching contacts on the route signal, these can be supplied by an already authorized PZB control box. This can be supplied from the lamp circuit due to its very low energy consumption. The supply of the further memory modules 5 with current / voltage takes place only when the associated switching contact 8 is closed in the switching unit 7, ie only when a passing vehicle feeds energy and a switching contact 8 is closed on the path signal, the balise 1 can the corresponding telegram to the vehicle. Depending on which switching contact 8 of the switching unit 7 is closed, different memory modules 5 are supplied with power. The balise 1 can then send the corresponding telegram to the passing vehicle. Which telegram is sent is thus selected according to the invention by external contacts (switching contacts 8 of the switching unit 7).

Zur Erzeugung der Telegramme ist die erfindungsgemäße Balise mit einem Signalgenerator 9 ausgestattet. Die weiteren Speicherbausteine 5 sind jeweils mit dem ersten Speicherbaustein 4 verbunden. Dies dient dazu, das Senden des Störungstelegramms zu deaktivieren, sobald einer der weiteren Speicherbausteine 5 aktiv ist und von ihm ein Telegramm gesendet wird. Dies kann auch direkt im Signalgenerator 9 geschehen, wenn dieser das Senden des Störungstelegramms einstellt, sobald er Telegramme von einem weiteren Speicherbaustein 5 erhält.To generate the telegrams Balise invention is equipped with a signal generator 9 . The further memory modules 5 are each connected to the first memory module 4. This serves to deactivate the transmission of the fault telegram as soon as one of the further memory blocks 5 is active and a telegram is sent from it. This can also be done directly in the signal generator 9, if this adjusts the transmission of the disturbance telegram as soon as it receives telegrams from another memory module 5.

Ein Fahrzeug, welches mit einer aktiven ETCS-Antenne über eine Balise fährt, erzeugt in der Empfangseinheit 2 der Balise 1 einen Strom, der zur Energieversorgung der Balise 1 verwendet wird. Die Balise 1 sendet über die Sendeeinrichtung 3 abhängig von ihrer Ansteuerung Telegramme an das Fahrzeug zurück.A vehicle, which travels over a balise with an active ETCS antenna, generates in the receiving unit 2 of the balise 1 a current which is used to supply energy to the balise 1. The balise 1 sends via the transmitting device 3 depending on their control telegrams to the vehicle back.

Die erfindungsgemäße Balise kann als Hauptsignalbalise, als Vorsignalbalise, als kombinierte Vor- und Hauptsignalbalise oder als weitere Balise zur Betriebsoptimierung (wie z.B. eine dem Hauptsignal vorgeschalteten Aufwertebalise), zur Geschwindigkeitsüberwachung oder an Überwachungssignalen eines Bahnübergangs, betrieben werden.The balise according to the invention can be used as a main signal balise, as a Vorsignalbalise, as combined Vor- and Hauptsignalbalise or as further Balise for operation optimization (such as a main signal upstream Revaluation beacon) for speed monitoring or monitoring signals of a level crossing.

Für den Fall, dass keine externe Ansteuerung erfolgt, d.h. wenn keiner der Schaltkontakte der Schalteinheit geschlossen ist, sendet die Balise 1 das im ersten Speicherbaustein 4 gespeicherte Störungstelegramm. Dies ist beispielsweise der Fall, wenn ein Halt-Befehl (HP0) am Streckensignal oder eine Störung (z.B. ein Kabelbruch) vorliegt. Ist aufgrund einer Signalanzeige einer der Schaltkontakte geschlossen (z.B. bei Signalbegriff KS1), wird der mit dem geschlossenen Schaltkontakt 8 verbundene Speicherbaustein 5 von der Empfangseinheit 2 mit Strom versorgt, so dass im Signalgenerator 9 das in dem entsprechenden weiteren Speicherbaustein 5 gespeicherte Telegramm (z.B. ein Fahrttelegramm) von dem Signalgenerator 9 erzeugt und von der Sendeeinrichtung 3 an das passierende Fahrzeug gesendet wird. Das Versenden der weiteren Telegramme kann nur bei Stromfluss durch die Schalteinheit 7 erfolgen, also nur wenn in der Empfangseinheit 2 Strom induziert wird und einer der Schaltkontakte 8 geschlossen ist. Ohne diese Energiezuführung können keine Fahrttelegramme gesendet werden. Ausschließlich das Störungstelegramm mit einem "restriktiven" Begriff.In the event that no external activation takes place, i. If none of the switching contacts of the switching unit is closed, the balise 1 sends the stored in the first memory module 4 fault telegram. This is the case, for example, when there is a halt command (HP0) on the path signal or a disturbance (e.g., a cable break). If, due to a signal display, one of the switching contacts is closed (eg with signal term KS1), the memory module 5 connected to the closed switching contact 8 is supplied with power by the receiving unit 2, so that in the signal generator 9 the telegram stored in the corresponding further memory module 5 (eg Running telegram) generated by the signal generator 9 and is sent by the transmitting device 3 to the passing vehicle. The sending of further telegrams can only be done with current flowing through the switching unit 7, that is, only when in the receiving unit 2 current is induced and one of the switching contacts 8 is closed. Without this energy supply no travel telegrams can be sent. Exclusively the fault telegram with a "restrictive" term.

Das erfindungsgemäße Zugsicherungssystem erlaubt das Versenden von verschiedenen Datentelegrammen ohne externe Energiequelle. Es ist keine Fremdspeisung notwendig. Der Stromversorgungschaltkreis für die Speicherbausteine wird durch das passierende Fahrzeug gespeist.The train protection system according to the invention allows the transmission of different data telegrams without external power source. There is no external power supply necessary. The power supply circuit for the memory modules is powered by the passing vehicle.

Optional kann die erfindungsgemäße Balise 1 mit einer weiteren Schnittstelle 10 ausgestattet sein, an die eine streckenseitige elektronische Einheit LEU angeschlossen werden kann. Auf diese Weise kann die erfindungsgemäße Balise 1 auch als europäisch konforme Balise in ETCS-Systemen eingesetzt werden.Optionally, the balise 1 according to the invention may be equipped with a further interface 10, to which a track-side electronic unit LEU can be connected. In this way, the balise 1 according to the invention can also be used as a European compliant balise in ETCS systems.
