So sind beispielsweise Sensoreinrichtungen in Form von insbesondere zur Gleisfreimeldung verwendeten Radsensoren im Bereich der Eisenbahnautomatisierung weit verbreitet.As part of the track-bound, in particular rail-bound traffic sensor devices for different tasks in connection with the monitoring and / or control of the respective vehicles, which may be in addition to rail vehicles, for example, track-guided vehicles with rubber tires used. For example, sensor devices in the form of wheel sensors used in particular for track release in the field of railway automation are widely used.
Entsprechende Radsensoren können beispielsweise als Doppelkontakt-Schienenschalter ausgeführt sein, deren elektrische Signale in nachfolgenden Verarbeitungseinrichtungen beziehungsweise Auswerteschaltungen aufbereitet und ausgewertet werden. Für die weitere Nutzung der aus den elektrischen Signalen abgeleiteten Information ist eine genaue Kenntnis des Ortes, d.h. der örtlichen Lage beziehungsweise Position der Sensoren im Gleisnetz, regelmäßig von erheblicher Bedeutung. Dies gilt beispielsweise für den Fall, dass die Radsensoren zur Gleisfreimeldung dienen und damit durch den Ort der Radsensoren die Grenzen der jeweiligen Gleisbelegungs- beziehungsweise Gleisfreimeldeabschnitte definiert werden.Corresponding wheel sensors can be designed, for example, as a double-contact rail switch whose electrical signals are processed and evaluated in subsequent processing devices or evaluation circuits. For further use of the information derived from the electrical signals, an accurate knowledge of the location, i. the location or position of the sensors in the rail network, regularly of considerable importance. This applies, for example, in the event that the wheel sensors are used for track release and thus the limits of the respective track occupancy or train detection sections are defined by the location of the wheel sensors.
Im Rahmen ihrer Inbetriebnahme werden Radsensoren üblicherweise an vorgegebenen Montageorten montiert und anlagenspezifisch verdrahtet. Die korrekte Montageverdrahtung wird hierbei in der Regel durch Inaugenscheinnahme, Vermessung und elektrische Überprüfung verifiziert. Mit den genannten Schritten sind im Rahmen der Projektierung erhebliche Aufwände verbunden; gleichzeitig sind die einzelnen Schritte aufgrund ihrer im Wesentlichen manuellen Durchführung vergleichsweise fehleranfällig, so dass Fehlzuordnungen beziehungsweise Fehlverkabelungen nur verbunden mit einem erheblichen Zusatzaufwand, beispielsweise durch ein Abfahren der Gleise mit einer Lokomotive, zuverlässig ausgeschlossen werden können.As part of their commissioning, wheel sensors are usually mounted at specified locations and wired system-specific. The correct mounting wiring is usually verified by visual inspection, surveying and electrical inspection. With the mentioned Steps are involved in the planning considerable effort; At the same time, the individual steps are relatively error-prone due to their essentially manual implementation, so that misallocations or miswiring can only be reliably prevented if a considerable additional effort is involved, for example, by driving off the tracks with a locomotive.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zum Erfassen von Projektierungsdaten einer Sensoreinrichtung zum Überwachen und/oder Steuern des spurgebundenen Verkehrs, wobei auf die Sensoreinrichtung bezogene Projektierungsdaten ermittelt werden, die ermittelten Projektierungsdaten in Form eines Informationsmusters auf die Sensoreinrichtung aufgeprägt werden, das aufgeprägte Informationsmuster von der Sensoreinrichtung an eine Verarbeitungseinrichtung übermittelt wird und die Projektierungsdaten von der Verarbeitungseinrichtung anhand des übermittelten Informationsmusters erfasst werden.This object is achieved by a method for acquiring configuration data of a sensor device for monitoring and / or controlling the track-bound traffic, wherein projecting data related to the sensor device are determined, the determined configuration data are impressed on the sensor device in the form of an information pattern, the impressed information pattern of the sensor device is transmitted to a processing device and the projecting data is acquired by the processing device on the basis of the transmitted information pattern.
Gemäß dem ersten Schritt des erfindungsgemäßen Verfahrens werden somit zunächst auf die Sensoreinrichtung bezogene Projektierungsdaten ermittelt. Diese Projektierungsdaten werden im nächsten Verfahrensschritt in Form eines Informationsmusters auf die Sensoreinrichtung aufgeprägt. Dies bedeutet, dass die Sensoreinrichtung mittels eines die Projektierungsdaten codierenden Informationsmusters angereizt beziehungsweise beaufschlagt wird. Durch eine entsprechende Anregung der Sensoreinrichtung beziehungsweise zumindest eines Sensors derselben werden die ermittelten Projektierungsdaten somit derart in die Sensoreinrichtung "eingespeist", dass von der Sensoreinrichtung ein Informationsmuster erfasst wird, welches die Projektierungsdaten derart codiert, dass diese aus dem Informationsmuster zurückgewonnen werden können. Vorzugsweise werden dabei für das Informationsmuster solche Abfolgen und Dauern der Anreizung beziehungsweise Auslösung der Sensoreinrichtung verwendet, die im normalen Betrieb, d.h. im Wirk- beziehungsweise Produktivbetrieb, der Sensoreinrichtung üblicherweise nicht auftreten. Für die Aufprägung des Informationsmusters auf die Sensoreinrichtung kann dabei eine Vielzahl bekannter Codierungsverfahren verwendet werden. In Abhängigkeit von der Art der jeweiligen Sensoreinrichtung schließt dies insbesondere eine Variation der Betätigungsfrequenz, der Betätigungsdauer sowie der Betätigungsrichtung der Sensoreinrichtung ein.According to the first step of the method according to the invention, first of all, configuration data related to the sensor device are determined. These configuration data are impressed on the sensor device in the next step in the form of an information pattern. This means that the sensor device is stimulated by means of an information pattern coding the configuration data is charged. By corresponding excitation of the sensor device or at least one sensor thereof, the determined configuration data are thus "fed" into the sensor device such that an information pattern is detected by the sensor device, which encodes the configuration data such that they can be recovered from the information pattern. Preferably, such sequences and durations of the triggering or triggering of the sensor device are used for the information pattern, which usually do not occur in normal operation, ie in active or productive operation, of the sensor device. In this case, a multiplicity of known coding methods can be used for impressing the information pattern on the sensor device. Depending on the nature of the respective sensor device, this includes in particular a variation of the actuation frequency, the actuation duration and the actuation direction of the sensor device.
Gemäß dem dritten Schritt des erfindungsgemäßen Verfahrens wird das aufgeprägte Informationsmuster von der Sensoreinrichtung an eine Verarbeitungseinrichtung übermittelt. Hierdurch werden somit mittels des Informationsmusters die Projektierungsdaten auf dieselbe Art und Weise an eine an die Sensoreinrichtung kommunikationstechnisch angebundene Verarbeitungseinrichtung übermittelt, wie dies auch für die im normalen Betrieb von der Sensoreinrichtung erfassten Daten beziehungsweise Signale geschieht. Mit anderen Worten wird somit der ohnehin vorhandene Kommunikationsweg zwischen der Sensoreinrichtung und der Verarbeitungseinrichtung dafür verwendet, die ermittelten Projektierungsdaten an die Verarbeitungseinrichtung zum übermitteln. Dies hat den grundlegenden Vorteil, dass hierdurch eine eindeutige und unmittelbare Zuordnung der übertragenen Projektierungsdaten zu der jeweiligen Sensoreinrichtung möglich ist und insbesondere anderenfalls denkbare Zuordnungsfehler oder Vertauschungen zuverlässig vermieden werden.According to the third step of the method according to the invention, the impressed information pattern is transmitted from the sensor device to a processing device. As a result, by means of the information pattern, the configuration data are thus transmitted in the same way to a processing device connected to the sensor device by communication, as is also the case for the data or signals acquired by the sensor device during normal operation. In other words, the already existing communication path between the sensor device and the processing device is thus used to transmit the determined configuration data to the processing device. This has the fundamental advantage that, as a result, a clear and direct assignment of the transferred configuration data to the respective Sensor device is possible and in particular otherwise conceivable assignment errors or permutations are reliably avoided.
Gemäß dem letzten Schritt des erfindungsgemäßen Verfahrens werden die Projektierungsdaten von der Verarbeitungseinrichtung anhand des übermittelten Informationsmusters erfasst. Dies bedeutet, dass die Projektierungsdaten von der Verarbeitungseinrichtung basierend auf dem empfangenen Informationsmuster durch eine entsprechende Decodierung bestimmt beziehungsweise zurückgewonnen werden. Damit sind die Projektierungsdaten im Ergebnis von der Sensoreinrichtung über den für die im Normalbetrieb erfassten Sensordaten beziehungsweise Sensorsignale vorgesehenen Übertragungsweg an die Verarbeitungseinrichtung übermittelt worden, wo sie zur weiteren Bearbeitung, Berücksichtigung und/oder Überprüfung zur Verfügung stehen.According to the last step of the method according to the invention, the configuration data are acquired by the processing device on the basis of the transmitted information pattern. This means that the projecting data are determined or recovered by the processing device based on the received information pattern by a corresponding decoding. As a result, the configuration data have been transmitted as a result of the sensor device via the transmission path provided for the sensor data or sensor signals detected in normal operation to the processing device, where they are available for further processing, consideration and / or review.
Entsprechend den vorstehenden Erläuterungen weist das erfindungsgemäße Verfahren somit den grundlegenden Vorteil auf, dass diejenige Sensoreinrichtung, auf die sich die ermittelten Projektierungsdaten beziehen, selbst für die Übermittlung der Projektierungsdaten an die Verarbeitungseinrichtung verwendet wird. Hieraus ergibt sich, dass das Verfahren aufgrund der Vermeidung zusätzlicher Übertragungswege oder einer manuellen Erfassung der Projektierungsdaten eine besonders hohe Zuverlässigkeit aufweist. Des Weiteren wird die Erfassung der Projektierungsdaten durch das erfindungsgemäße Verfahren erheblich vereinfacht und beschleunigt, so dass sich insbesondere im Hinblick auf die Inbetriebnahme von Anlagen mit einer Vielzahl von Sensoreinrichtungen in der Praxis erhebliche Vorteile ergeben.In accordance with the above explanations, the method according to the invention thus has the fundamental advantage that the sensor device to which the determined configuration data relate is itself used for the transmission of the configuration data to the processing device. It follows that the method has a particularly high reliability due to the avoidance of additional transmission paths or manual detection of the configuration data. Furthermore, the acquisition of the configuration data by the method according to the invention is considerably simplified and accelerated, so that in practice, in particular with regard to the commissioning of systems with a large number of sensor devices, considerable advantages result in practice.
Gemäß einer besonders bevorzugten Weiterbildung des erfindungsgemäßen Verfahrens werden die Projektierungsdaten von der Verarbeitungseinrichtung mit einer die Sensoreinrichtung kennzeichnenden Identität verknüpft. Dies ist vorteilhaft, da hierdurch eine eindeutige und dauerhafte Zuordnung der erfassten Projektierungsdaten zu der jeweiligen Sensoreinrichtung gewährleistet wird. Die die Sensoreinrichtung kennzeichnende Identität kann von der Verarbeitungseinrichtung dabei beispielsweise dem Signal entnommen werden, mittels dessen das aufgeprägte Informationsmuster von der Sensoreinrichtung an die Verarbeitungseinrichtung übermittelt wird. Alternativ hierzu ist es beispielsweise auch denkbar, dass die die Sensoreinrichtung kennzeichnende Identität von der Verarbeitungseinrichtung entsprechenden Konfigurationsdaten entnommen wird.According to a particularly preferred development of the method according to the invention, the configuration data are linked by the processing device with an identity characterizing the sensor device. This is advantageous, as this ensures a clear and permanent assignment of the acquired configuration data to the respective sensor device. The identity characterizing the sensor device can be taken from the processing device, for example, the signal by means of which the impressed information pattern is transmitted from the sensor device to the processing device. Alternatively, it is also conceivable, for example, for the identity characterizing the sensor device to be taken from configuration data corresponding to the processing device.
Bei den auf die Sensoreinrichtung bezogenen Projektierungsdaten, die ermittelt und letztlich von der Verarbeitungseinrichtung anhand des übermittelten Informationsmusters erfasst werden, kann es sich grundsätzlich um Projektierungsdaten beliebiger Art handeln.In the case of the configuration data related to the sensor device, which are determined and ultimately acquired by the processing device on the basis of the transmitted information pattern, it is possible in principle to be any kind of configuration data.
Gemäß einer weiteren besonders bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens werden auf den Ort der Sensoreinrichtung bezogene Daten als Projektierungsdaten erfasst. Dies ist vorteilhaft, da der Ort der Sensoreinrichtung, d.h. beispielsweise die Lage beziehungsweise genaue Position eines Radsensors in einem Gleisnetz, im Rahmen der Projektierung von besonderer Bedeutung ist. So ist insbesondere auch in rangiertechnischen Anlagen eine exakte Kenntnis des Ortes der im Rahmen der Überwachung und Steuerung der Anlage verwendeten Sensoreinrichtungen von großer Bedeutung. Vorteilhafterweise kann das erfindungsgemäße Verfahren auch derart weitergebildet sein, dass die auf den Ort der Sensoreinrichtung bezogenen Daten satellitengestützt ermittelt werden. Die satellitengestützte Ermittlung der auf den Ort der Sensoreinrichtung bezogenen Daten, d.h. beispielsweise unter Verwendung eines GPS-, GLONASS- oder Galileo-Satellitenempfängers, ist vorteilhaft, da hierdurch eine vergleichsweise genaue und aufwandsarme Orts- beziehungsweise Positionsermittlung ermöglicht wird.According to a further particularly preferred embodiment of the method according to the invention, data related to the location of the sensor device are acquired as configuration data. This is advantageous because the location of the sensor device, ie, for example, the position or exact position of a wheel sensor in a track network, is of particular importance in the context of the configuration. Thus, an exact knowledge of the location of the sensor devices used in the context of monitoring and control of the system is also of great importance, especially in technical installations. Advantageously, the method according to the invention can also be developed in such a way that the data related to the location of the sensor device are determined by satellite assistance. The satellite-based determination of the data related to the location of the sensor device, ie, for example, using a GPS, GLONASS or Galileo satellite receiver, is advantageous, since this allows a comparatively accurate and low-cost location or position determination.
Vorzugsweise kann das erfindungsgemäße Verfahren weiterhin derart weitergebildet sein, dass auf eine Sensoreinrichtung in Form eines Radsensors bezogene Projektierungsdaten erfasst werden. Dies ist vorteilhaft, da Radsensoren bei der Überwachung und Steuerung des schienengebundenen Verkehrs eine zentrale Funktion zukommt. Dabei ist eine genaue Erfassung der Projektierungsdaten von Radsensoren, insbesondere in Form von auf den Ort des jeweiligen Radsensors bezogenen Daten, von zentraler Bedeutung. Dies gilt sowohl für zum Zweck der Gleisfreimeldung eingesetzte als auch beispielsweise für zum Zweck der Messung von Geschwindigkeiten oder Laufwiderständen verwendete Radsensoren. So ist beispielsweise bei rangiertechnischen Ablaufanlagen eine genaue Kenntnis des Ortes zur Detektion ablaufender Wagen beziehungsweise Wagengruppen verwendeter Radsensoren für eine zuverlässige und die Leistungsfähigkeit der Anlage optimierende Steuerung des Ablaufbetriebes von großer Bedeutung.Preferably, the method according to the invention can also be further developed in such a way that configuration data related to a sensor device in the form of a wheel sensor are detected. This is advantageous because wheel sensors play a central role in the monitoring and control of rail-bound traffic. In this case, an accurate detection of the configuration data of wheel sensors, in particular in the form of data related to the location of the respective wheel sensor, is of central importance. This applies both for the purposes of track vacancy used as well as for example for the purpose of measuring speeds or running resistors used wheel sensors. Thus, for example, in the case of technical draining systems, an exact knowledge of the location for the detection of running wagons or groups of wagon used wheel sensors for a reliable and the performance of the system optimizing control of the flow operation of great importance.
Das Aufprägen des Informationsmusters auf die Sensoreinrichtung in Form eines Radsensors kann in Abhängigkeit von dem Wirkprinzip des jeweiligen Radsensors auf unterschiedliche Art und Weise erfolgen. So ist es im Falle eines magnetisch wirkenden Radsensors beispielsweise denkbar, dass das Aufprägen des Informationsmusters auf die Sensoreinrichtung unter Verwendung einer magnetischen Abschirmung erfolgt. Des Weiteren bereitet es dem Fachmann auch im Falle von mechanisch, hydraulisch oder pneumatisch wirkenden Radsensoren keine Probleme, in Abhängigkeit von der konkreten konstruktiven Ausführung des jeweiligen Radsensors eine Betätigungseinrichtung zu realisieren, die das Aufprägen des Informationsmusters auf die Sensoreinrichtung ermöglicht.The impressing of the information pattern on the sensor device in the form of a wheel sensor can be carried out in different ways depending on the operating principle of the respective wheel sensor. For example, in the case of a magnetically acting wheel sensor, it is conceivable that the impressing of the information pattern on the sensor device is undermined Use of a magnetic shield takes place. Furthermore, even in the case of mechanically, hydraulically or pneumatically acting wheel sensors, it is no problem for the person skilled in the art to realize an actuating device which makes it possible to apply the information pattern to the sensor device, depending on the specific structural design of the respective wheel sensor.
Gemäß einer weiteren besonders bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens wird das Informationsmuster durch eine Abfolge von gezielten Bedämpfungen des Magnetfeldes zumindest einer Sensorspule des Radsensors auf den Radsensor aufgeprägt. Dies betrifft somit den Fall eines induktiv wirkenden Radsensors, der zur Erfassung vorbeirollender Räder zumindest eine Sensorspule aufweist. Durch eine gezielte Bedämpfung der Sensorspule beziehungsweise ihres Magnetfeldes ist es hierbei unter Verwendung eines entsprechenden Codierungsverfahrens somit möglich, das Informationsmuster auf den Radsensor aufzuprägen. Dies ist vorteilhaft, da induktiv wirkende Radsensoren insbesondere aufgrund ihrer Robustheit und Zuverlässigkeit im Bereich des Schienenverkehrs weitverbreitet sind.According to a further particularly preferred embodiment of the method according to the invention, the information pattern is impressed on the wheel sensor by a sequence of targeted attenuations of the magnetic field of at least one sensor coil of the wheel sensor. This therefore relates to the case of an inductively acting wheel sensor which has at least one sensor coil for detecting passing wheels. By a targeted damping of the sensor coil or its magnetic field, it is thus possible to impose the information pattern on the wheel sensor using a corresponding coding method. This is advantageous since inductively acting wheel sensors are widespread in the field of rail transport, in particular because of their robustness and reliability.
Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ausgeprägt sein, dass auf eine Sensoreinrichtung in Form einer Lichtschranke, eines Lichtgitters, eines Sensors zum Messen von Achslasten, eines Beschleunigungssensors oder eines Lagesensors bezogene Projektierungsdaten erfasst werden. Dies ist vorteilhaft, da es sich bei den genannten Arten von Sensoreinrichtungen einerseits um solche handelt, die insbesondere im Rahmen der Steuerung und Überwachung von rangiertechnischen Anlagen gebräuchlich sind. Andererseits sind diese Sensoreinrichtungen auch aufgrund ihres Wirkprinzips besonders geeignet dafür, durch das Aufprägen eines entsprechenden Informationsmusters erfasste Projektierungsdaten an eine an die jeweilige Sensoreinrichtung kommunikationstechnisch angebundene Verarbeitungseinrichtung zu übertragen. Das Anreizen der Sensoreinrichtung in der Art, dass ein die jeweiligen Projektierungsdaten codierendes Signal an die Verarbeitungseinrichtung übertragen wird, erfolgt hierbei in einer von der Art der jeweiligen Sensoreinrichtung abhängigen Art und Weise. So kann im Falle einer Sensoreinrichtung in Form einer Lichtschranke oder eines Lichtgitters durch das gezielte Einbringen eines Gegenstands in den Erfassungsbereich der Sensoreinrichtung ein Aufprägen der ermittelten Projektierungsdaten auf die Sensoreinrichtung beziehungsweise ein Signal derselben erfolgen. Im Falle der weiteren genannten bevorzugten Ausführungsformen der Sensoreinrichtung ist zum Aufprägen der Projektierungsdaten ein Anreizen der jeweiligen Sensoreinrichtung beispielsweise mittels entsprechender mechanischer Betätigungen, sich ändernder Beschleunigungen oder - im Falle eines Lagesensors - sich ändernder Lagen, Neigungen beziehungsweise Orientierungen möglich.Preferably, the method according to the invention can also be so pronounced that configuration data relating to a sensor device in the form of a light barrier, a light grid, a sensor for measuring axle loads, an acceleration sensor or a position sensor are detected. This is advantageous since the types of sensor devices mentioned on the one hand are those which are customary, in particular, in the context of control and monitoring of technical installations. On the other hand, these sensor devices are also due to their principle of action particularly suitable for this, by imprinting a corresponding Information pattern acquired to transfer configuration data to a communication device connected to the respective sensor device processing means. The stimulation of the sensor device in such a way that a signal encoding the respective configuration data is transmitted to the processing device takes place here in a manner dependent on the type of the respective sensor device. Thus, in the case of a sensor device in the form of a light barrier or a light grid, the targeted introduction of an object into the detection area of the sensor device can imprint the determined configuration data on the sensor device or a signal thereof. In the case of the further mentioned preferred embodiments of the sensor device for impressing the project planning data, an incentive of the respective sensor device is possible, for example by means of corresponding mechanical actuations, changing accelerations or - in the case of a position sensor - changing positions, inclinations or orientations.
Die Übermittlung des aufgeprägten Informationsmusters von der Sensoreinrichtung an die Verarbeitungseinrichtung kann im Rahmen des erfindungsgemäßen Verfahrens auf einen beliebigen Kommunikationsweg erfolgen. Dies schließt insbesondere eine drahtgebundene Übermittlung ein.The transmission of the impressed information pattern from the sensor device to the processing device can take place in the context of the inventive method on any communication path. This includes, in particular, a wired transmission.
Vorzugsweise kann das erfindungsgemäße Verfahren auch derart ausgestaltet sein, dass das aufgeprägte Informationsmuster von der Sensoreinrichtung drahtlos, insbesondere funkbasiert, an die Verarbeitungseinrichtung übermittelt wird. Dies ist vorteilhaft, da eine drahtlose Übermittlung von Daten beziehungsweise Signalen von Sensoreinrichtungen in der Praxis dahingehend erhebliche Vorteile aufweist, dass teure und vergleichsweise aufwändige Verkabelungsarbeiten, beispielsweise im Gleisbereich, vermieden werden. Darüber hinaus ist im Falle einer funkbasierten Übermittlung von Daten beziehungsweise Signalen zwischen der Sensoreinrichtung und der Verarbeitungseinrichtung eine zuverlässige Erfassung von Projektierungsdaten der Sensoreinrichtung, insbesondere ihres Ortes, in Abhängigkeit von den jeweiligen Umständen von besonderer Bedeutung. Vorteilhafterweise wird es der Verarbeitungseinrichtung hierdurch weiterhin ermöglicht, Kenntnisse darüber zu erlangen, welche Sensoreinrichtungen ihr dahingehend zugeordnet sind, dass die Verarbeitungseinrichtung für das Empfangen und Auswerten von Daten beziehungsweise Signalen dieser Sensoreinrichtungen zuständig ist. Eine entsprechende Kenntnis seitens der Verarbeitungseinrichtung ist insbesondere im Falle einer funkbasierten Übermittlung von Bedeutung, da die Verarbeitungseinrichtung in diesem Fall funktechnisch möglicherweise auch in der Lage ist, Signale von anderen, für sie nicht relevanten Komponenten zu empfangen.Preferably, the inventive method can also be configured such that the impressed information pattern is transmitted wirelessly from the sensor device, in particular radio-based, to the processing device. This is advantageous since a wireless transmission of data or signals from sensor devices in practice has significant advantages in that expensive and comparatively complicated wiring work, for example in the track area, to be avoided. In addition, in the case of a radio-based transmission of data or signals between the sensor device and the processing device, a reliable detection of configuration data of the sensor device, in particular its location, depending on the particular circumstances of particular importance. Advantageously, this also allows the processing device to gain knowledge about which sensor devices are assigned to it in such a way that the processing device is responsible for receiving and evaluating data or signals of these sensor devices. A corresponding knowledge on the part of the processing device is of importance, in particular, in the case of a radio-based transmission, since in this case the processing device may possibly also be able to receive signals from other components which are not relevant to it.
Hinsichtlich der Einrichtung zum Erfassen von Projektierungsdaten einer Sensoreinrichtung zum Überwachen und/oder Steuern des spurgebundenen Verkehrs liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Einrichtung anzugeben, die ein besonders leistungsfähiges und zugleich besonders zuverlässiges Verfahren zum Erfassen von Projektierungsdaten einer entsprechenden Sensoreinrichtung unterstützt.With regard to the device for acquiring configuration data of a sensor device for monitoring and / or controlling the track-bound traffic, the object of the present invention is to provide a device which supports a particularly efficient and at the same time particularly reliable method for acquiring configuration data of a corresponding sensor device.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Einrichtung zum Erfassen von Projektierungsdaten einer Sensoreinrichtung zum Überwachen und/oder Steuern des spurgebundenen Verkehrs, wobei die Einrichtung ausgebildet ist, auf die Sensoreinrichtung bezogene Projektierungsdaten zu ermitteln und die ermittelten Projektierungsdaten in Form eines Informationsmusters auf die Sensoreinrichtung aufzuprägen zwecks Übermittlung des aufgeprägten Informationsmusters von der Sensoreinrichtung an eine Verarbeitungseinrichtung und Erfassung der Projektierungsdaten anhand des übermittelten Informationsmusters durch die Verarbeitungseinrichtung.This object is achieved according to the invention by a device for acquiring configuration data of a sensor device for monitoring and / or controlling the track-bound traffic, wherein the device is designed to determine configuration data related to the sensor device and impose the determined configuration data in the form of an information pattern on the sensor device Transmission of the impressed information pattern from the sensor device to a processing device and acquisition of the configuration data on the basis of the transmitted information pattern by the processing device.
Die Vorteile der erfindungsgemäßen Einrichtung entsprechen im Wesentlichen denjenigen des erfindungsgemäßen Verfahrens, so dass diesbezüglich auf die entsprechenden vorstehenden Ausführungen verwiesen wird. Gleiches gilt hinsichtlich der im Folgenden genannten bevorzugten Weiterbildungen der erfindungsgemäßen Einrichtung in Bezug auf die entsprechenden bevorzugten Weiterbildungen des erfindungsgemäßen Verfahrens, so dass zur Vermeidung von Wiederholungen auch diesbezüglich auf die entsprechenden vorstehenden Erläuterungen verwiesen wird.The advantages of the device according to the invention essentially correspond to those of the method according to the invention, so that in this regard reference is made to the corresponding explanations above. The same applies to the preferred developments of the device according to the invention referred to below with regard to the corresponding preferred developments of the method according to the invention, so that in order to avoid repetition reference is also made in this regard to the corresponding explanations given above.
Gemäß einer besonders bevorzugten Weiterbildung ist die erfindungsgemäße Einrichtung ausgebildet, auf eine Sensoreinrichtung in Form eines Radsensors bezogene Projektierungsdaten zu erfassen und die ermittelten Projektierungsdaten in Form eines Informationsmusters auf den Radsensor aufzuprägen.According to a particularly preferred development, the device according to the invention is designed to detect configuration data related to a sensor device in the form of a wheel sensor and to impart the determined configuration data in the form of an information pattern to the wheel sensor.
Vorzugsweise kann die erfindungsgemäße Einrichtung auch derart weitergebildet sein, dass die Einrichtung eine auf den Radsensor aufsetzbare Betätigungseinrichtung aufweist und die Betätigungseinrichtung ausgebildet ist, das Informationsmuster durch eine Abfolge von gezielten Bedämpfungen des Magnetfeldes zumindest einer Sensorspule des Radsensors auf den Radsensor aufzuprägen.Preferably, the device according to the invention can also be developed in such a way that the device has an actuating device which can be placed on the wheel sensor and the actuating device is designed to impose the information pattern on the wheel sensor by a sequence of targeted damping of the magnetic field of at least one sensor coil of the wheel sensor.
Gemäß einer weiteren besonders bevorzugten Ausführungsform ist die erfindungsgemäße Einrichtung zum Ermitteln von auf den Ort bezogenen Daten als Projektierungsdaten ausgebildet. Vorzugsweise kann die erfindungsgemäße Einrichtung auch derart ausgestaltet sein, dass sie zum Ermitteln der auf den Ort bezogenen Daten einen Satellitenempfänger aufweist. Bei dem Satellitenempfänger kann es sich beispielsweise um einen GPS-Empfänger beziehungsweise ein GPS-Gerät handeln, d.h. eine Vorrichtung, die zur satellitengestützten Orts- beziehungsweise Positionsermittlung unter Verwendung des Global Positioning Systems (GPS) ausgebildet ist. Alternativ oder zusätzlich hierzu kann der Satellitenempfänger auch zum Empfang von Signalen anderer Satellitennavigationssyteme, wie beispielsweise Galileo oder GLONASS, ausgebildet sein.According to a further particularly preferred embodiment, the device according to the invention for determining data relating to the location is designed as configuration data. Preferably, the device according to the invention can also be designed such that it has a satellite receiver for determining the data relating to the location. The satellite receiver can be, for example, a GPS receiver or a GPS device, ie a device that is designed for satellite-supported location or position determination using the Global Positioning System (GPS). Alternatively or additionally, the satellite receiver can also be designed to receive signals from other satellite navigation systems, such as Galileo or GLONASS.
Gemäß einer weiteren besonders bevorzugten Ausführungsform ist die erfindungsgemäße Einrichtung zum Bestimmen ihrer Ausrichtung in Bezug auf eine weitere im Bereich der Sensoreinrichtung angeordnete Komponente, insbesondere eine Weiche, ausgebildet. Hierdurch soll die Einrichtung vorteilhafterweise letztlich dazu in die Lage versetzt werden, eine Überprüfung der Ausrichtung der Sensoreinrichtung zu ermöglichen, um hierdurch fehlerhafte Zuordnungen vermeiden beziehungsweise erkennen zu können.According to a further particularly preferred embodiment, the device according to the invention for determining its orientation with respect to a further arranged in the region of the sensor device component, in particular a switch, is formed. In this way, the device should advantageously ultimately be enabled to enable a check of the orientation of the sensor device, in order to avoid or detect erroneous assignments.
Im Falle von zur Überwachung beispielsweise einer elektrisch ortsgestellten Weiche verwendeten Sensoreinrichtungen in Form von Radsensoren kann dies beispielsweise bedeuten, dass es die Einrichtung, beispielsweise durch eine Winkelmessung oder durch Bildauswertung, ermöglicht, zwischen an der rechten beziehungsweise linken stumpfen Seite der Weiche montierten Radsensoren zu unterscheiden und somit dahingehend eine Konsistenzprüfung vorzunehmen. Hierzu ist einerseits eine entsprechende mechanische Ausbildung der Einrichtung denkbar, welche eine Bestimmung der Ausrichtung der Einrichtung in Bezug auf die elektrisch ortsgestellte Weiche erlaubt. Alternativ oder zusätzlich hierzu ist es beispielsweise auch denkbar, dass die Einrichtung eine Kamera aufweist und diese auf einen Weichenlagemelder der elektrisch ortsgestellten Weiche ausgerichtet wird. Durch eine Auswertung des Bildsignals der Kamera kann hierbei das Meldebild des Weichenlage- und Ordnungsmelders erfasst werden. Mittels des erfassten Meldebildes ist es hieraufhin möglich, die korrekte Ausrichtung der Einrichtung in Bezug auf den Weichelage- und Ordnungsmelder und dementsprechend auch in Bezug auf die Weiche zu bestätigen und damit im Ergebnis die Ausrichtung der Einrichtung in Bezug auf die Weiche zu bestimmen. Zur weiteren Erhöhung der Sicherheit des Erfassens der Projektierungsdaten ist es darüber hinaus beispielsweise denkbar, dass seitens einer Steuereinrichtung der elektrisch ortsgestellten Weiche in einem Konfigurationsmodus ein definiertes Konfigurations-Meldebild, das im normalen Betrieb nicht auftritt, auf dem Weichenlage- und Ordnungsmelder angezeigt wird. Im Falle eines Weichenlage- und Ordnungsmelders für eine normale Weiche könnte es sich hierbei beispielsweise um ein Aufleuchten aller drei Lichtpunkte oder auch ein Aufleuchten der Lichtpunkte mit einer spezifischen Blinkfrequenz handeln. Ein fehlerfreies Erfassen der Projektierungsdaten ist in diesem Fall nur dann möglich, wenn anhand des Kamerabildes von einer Auswertelogik das erwartete Muster erkannt wird. Mittels einer entsprechenden Kameraeinrichtung ist es vorteilhafterweise darüber hinaus auch möglich, für jede der Sensoreinrichtungen in Form von Radsensoren zur Dokumentation im Rahmen der Projektierung ein Bild beziehungsweise Foto zu speichern, auf dem die auf dem Weichenlage- und Ordnungsmelder angeschriebene Nummer der zugehörigen elektrisch ortsgestellten Weiche enthalten ist.In the case of sensor devices in the form of wheel sensors used for monitoring, for example, an electrically localized switch, this can mean, for example, that the device makes it possible, for example by angle measurement or image evaluation, to distinguish between wheel sensors mounted on the right and left blunt sides of the switch and thus to carry out a consistency check. For this purpose, on the one hand a corresponding mechanical design of the device is conceivable, which allows a determination of the orientation of the device with respect to the electrically localized switch. Alternatively or additionally, for example, it is also conceivable that the device has a camera and this is aligned with a switch position indicator of the electrically located switch. By evaluating the image signal of the camera, the message image of the switch position and order detector can be detected. By means of the recorded message image, it is then possible to confirm the correct alignment of the device with respect to the softness and order detector and, accordingly, also with respect to the switch and, as a result, to determine the orientation of the device with respect to the switch. To further increase the security of the acquisition of the configuration data, it is also conceivable, for example, that a control device of the electrically located switch in a configuration mode, a defined configuration message image that does not occur in normal operation, is displayed on the turnout and order detector. In the case of a switch position and order detector for a normal switch, this could be, for example, an illumination of all three points of light or a lighting up of the points of light with a specific blinking frequency. In this case, error-free acquisition of the configuration data is only possible if the expected pattern is recognized by an evaluation logic based on the camera image. By means of a corresponding camera device, it is advantageously also possible, for each of the sensor devices in the form of wheel sensors for documentation in the context of project planning to store an image or photo on which the number inscribed on the switch position and order detector number of the associated electrically localized turnout is.
Basierend auf einer Bestimmung der Ausrichtung der Einrichtung in Bezug auf eine weitere im Bereich einer Sensoreinrichtung in Form eines Radsensors angeordnete Komponente besteht hierbei vorteilhafterweise weiterhin die Möglichkeit, dass im Falle eines Radsensors mit mehreren, insbesondere zwei Sensorspulen das Informationsmuster nacheinander auf die beiden Sensorspulen aufgeprägt wird und aus der zeitlichen Reihenfolge seitens der Verarbeitungseinrichtung auf die Reihenfolge der Sensorspulen, etwa bezogen auf ihren Abstand von einer Weiche, geschlossen wird. Hierdurch kann somit in automatischer Weise die Betätigungsrichtung der Sensoreinrichtung bestimmt werden.Based on a determination of the orientation of the device with respect to a further component arranged in the region of a sensor device in the form of a wheel sensor, there is advantageously still the possibility of that in the case of a wheel sensor having a plurality of, in particular two sensor coils, the information pattern is successively impressed on the two sensor coils and from the chronological order on the part of the processing device on the order of the sensor coils, approximately related to their distance from a switch, is closed. As a result, the actuation direction of the sensor device can thus be determined in an automatic manner.
Die Erfindung umfasst des Weiteren eine Anordnung mit einer erfindungsgemäßen Einrichtung oder einer Einrichtung gemäß einer der zuvor beschriebenen bevorzugten Weiterbildungen der erfindungsgemäßen Einrichtung sowie mit der Sensoreinrichtung und der Verarbeitungseinrichtung zum Erfassen der Projektierungsdaten anhand des übermittelten Informationsmusters.The invention further includes an arrangement having a device or a device according to one of the previously described preferred developments of the device according to the invention as well as with the sensor device and the processing device for detecting the configuration data on the basis of the transmitted information pattern.

Für eine korrekte und sichere Funktionsweise der Weiche 10 ist eine korrekte Projektierung der Radsensoren 50, 60, 70 in Bezug auf die Weiche 10 sicherzustellen. Hierzu ist insbesondere zu überprüfen, dass genau die Radsensoren 50, 60 und 70 der Weiche 10 zugeordnet sind und nicht etwa beispielsweise solche, die in ihrer Nachbarschaft montiert sind. Des Weiteren ist zu gewährleisten, dass es sich bei dem Radsensor 50 um den Radsensor vor der Weichenspitze handelt und die Betätigungsrichtung des Radsensors 50 hinsichtlich der Weichenspitze korrekt zugeordnet wird. Weiterhin ist zu verifizieren, dass es sich bei den Radsensoren 60 beziehungsweise 70 um die Radsensoren am rechten beziehungsweise linken stumpfen Ende der Weiche 10 handelt und hinsichtlich der Abstände d1, d2 und d3 zwischen den Radsensoren 50, 60 und 70 und der Weiche 10 erforderliche Mindestabstände eingehalten sind.For a correct and safe operation of the

Im Rahmen des beschriebenen Ausführungsbeispiels sei angenommen, dass es sich bei dem Radsensor 110 um einen induktiv wirkenden Radsensor in Form eines Doppelkontakt-Schienenschalters handelt. Zur Durchführung des zuvor beschriebenen Verfahrens weist die Einrichtung 200 zum Erfassen der Projektierungsdaten daher eine Betätigungseinrichtung 210 auf, die auf den montierten Radsensor 110 aufsetzbar ist und in der Lage ist, die beiden internen Sensoren des Radsensors 110 für kurze Zeiträume vorgebbarer Länge gezielt zu bedämpfen beziehungsweise nicht zu bedämpfen. Dies kann beispielsweise durch jeweils kurzzeitiges mechanisches Einschwenken einer kleinen Metallfläche über den jeweiligen Einzelsensor erfolgen. In Abhängigkeit von der konkreten Ausführung des Radsensors 110 wäre alternativ hierzu beispielsweise auch eine nicht mechanische, sondern elektrische Beeinflussung denkbar.In the context of the exemplary embodiment described, it is assumed that the

Zur Erfassung von auf die Sensoreinrichtung in Form des Radsensors 110 bezogenen Projektierungsdaten wird nun in einem ersten Schritt mittels des Satellitenempfängers 260 der Ort beziehungsweise die Position des Radsensors 110 mit hoher Genauigkeit ermittelt. Mittels der Steuereinrichtung 240 und der an diese kommunikationstechnisch angebundenen Betätigungseinrichtung 210 wird sodann ein die Projektierungsdaten in Form des ermittelten Ortes codierendes Informationsmuster auf den Radsensor 110 aufgeprägt. Dies bedeutet, dass mittels gezielter Bedämpfungen der Radsensor 110 derart angereizt wird, dass das resultierende Signal beziehungsweise dass durch dieses transportierte Informationsmuster für die ermittelten Projektierungsdaten spezifisch ist. Vorzugsweise werden zur Erzeugung des Informationsmusters hierbei Abfolgen von bedämpften und unbedämpften Zuständen und entsprechende Dauern verwendet, die im normalen Betrieb des Radsensors 110 nicht auftreten können. Für die Auf- beziehungsweise Einprägung der Information, d.h. der Projektierungsdaten, kann hierbei eine Vielzahl für sich bekannter Codierungsverfahren verwendet werden. Dies schließt insbesondere eine Variation der Betätigungsfrequenz, der Betätigungsdauer und/oder einen Wechsel der Betätigungsrichtung des Radsensors 110 durch die Betätigungseinrichtung 210 ein. Durch das mechanische Aufsetzen der Betätigungseinrichtung 210 auf die Sensoreinrichtung in Form des Radsensors 110 ist hierbei auf einfachste Weise sichergestellt, dass die ermittelten Projektierungsdaten unzweifelhaft auf genau diesen Radsensor 110 aufgeprägt und damit an die diesem zugeordnete Verarbeitungseinrichtung übermittelt werden.For detecting projecting data related to the sensor device in the form of the
