Definitions
- the condition of a track section in particular the occupancy, is usually determined by personnel without further technical aids. Accounting, ie theoretical track mirrors can be created using a disposition system.
- the cars are electronically converted by shunting from one track to another.
- Gleistore There are so-called "Gleistore" known. On a Gleistor a mark on the vehicles can be recognized optically or by radio. For this example, RFID tags are used. With the Gleistoren the track condition can be determined vehicle-accurate. However, this requires that a technically complex optical recognition and evaluation system is installed on the track or all vehicles are provided with a suitable marking.
- axle counters There are known as axle counters.
- the axle counters are used in interlocking-operated areas.
- the number of axes is usually not the operator and transport companies not shown.
- EP 0 433 756 A2 discloses a system for controlling and monitoring freight wagons. Each individual freight car is equipped with an individual identification mark. The system allows a clear identification of the smallest subunit (individual vehicle) and thus a high probability of identification. The equipment of all vehicles of an existing fleet of vehicles with appropriate individual identification marks is expensive and requires a long equipment time. Traction vehicles are not provided for identification.
- DD 2 29 657 A1 discloses a method for determining the number of vehicles, the center distances, the individual vehicle lengths and the total length of a vehicle body for operation on a runoff hill.
- the center distances are determined by means of two track switching devices.
- the track switching devices are arranged at a smaller distance than the smallest center distance of a bogie.
- the determination is made the average axis speeds, the time intervals between the set-up operation and the complete passage of the track switching devices.
- the axle distances determined in this way are compared with specified type-specific reference values for vehicle type determination.
- DE 198 36 421 A1 and EP 0 979 765 A2 disclose a method for the time-delayed transmission of a count determined by a metering point after complete passage of a train to a central evaluation device.
- the evaluation device generates only a free message or a busy message.
- an expectancy period is calculated based on the speed.
- maneuvering where the vehicle group could also stop at the metering point, the procedure fails. It is only suitable for generating a free or busy message for trips with almost constant speed, but not to represent the actual degree of occupancy.
- EP 1 086 873 A1 discloses a method for detecting rail vehicle wheels overrun at a point of delivery.
- the number of different influences on the sensors is counted by at least two sensors which are overlappingly influenced by the vehicle wheel, but plausibilized only after an expected period of time and the number of vehicle wheels is determined.
- US 2012/0138752 A1 discloses a compact evaluation circuit, which serves as An Havenmelder, but can not be used for track occupancy.

So it can be very accurately determined how many axes the sensors actually happened. Since the device does not give track approval, but only determines the crossing, no additional backups are required. Accordingly, the device is inexpensive to implement.
- the transmission means comprise a GSM module.
- the evaluation unit can be a remote server which receives data from a multiplicity of devices according to the invention.
- the transmission means transmit the "raw data". This avoids complex on-site logic. The data is transmitted immediately. It is not necessary to wait for the complete passage of all vehicles and to install corresponding time delays before transmission.
- the use of a wireless remote data transmission has the advantage that the device according to the invention is completely self-sufficient. It can be mounted anywhere on the track. It is easy to send and ready to use. There is no time-consuming electronic device or software installation required.
- the data can be sent with an identifier, which is assigned to the position, for example in the evaluation unit.

- the device according to the invention is self-sufficient and does not need to be connected to any power or other data networks.
- a solar module avoids high maintenance, such as the replacement of batteries.
- the device according to the invention can be operated by a method according to claim 6. It can also be detected in particular when a vehicle with an axle between the sensors stops.
- a passage in the direction from sensor 1 to sensor 2 generates the following signal sequence: step Sensor 1 Sensor 2 evaluation A 0 0 no crossing yet B 1 0 Sensor 1 is run over C 1 1 1 Axis is located between the sensors D 0 1 Sensor 2 is run over e 0 0 Crossing finished
- steps B and D are reversed. From the sequence of the crossing signals of the sensors so the direction of travel of the vehicle is determined. In addition, a crossing is verified according to the invention. Incorrect signals on one of the two sensors are easily identified as such if the associated signals are not generated on the other sensor.
- the speed of the axis can additionally be determined.
- the time of crossing a vehicle axle via the sensors or the time interval of the crossing between the sensors can be determined and transmitted to the evaluation unit.
- the distance of the sensors in the longitudinal direction can be transmitted to the evaluation unit or stored in the evaluation unit and the vehicle speed can be determined from the distance between the sensors and the time difference between the crossing signals of a vehicle axle.
- FIG. 1 shows a generally designated 10 device for detecting track sections.
- the device 10 comprises a base plate 12, which is arranged below the rail foot of a track 14 and protrudes on both sides.

- an induction sensor 26 is screwed on each leg 22 of the holder 18.
- the sensors 26 can be adjusted in this way together in the vertical direction. This is particularly helpful for adapting to the wear rate of the rail.
- the horizontal adjustment for different rail profiles can be done by moving the device.
- the base plate 12 is provided with offset threaded holes 24 corresponding to the different rail foot widths. Tapped holes have the advantage that tools do not have to be applied from below.
- the sensors 26 are arranged such that, when crossing a wheel 34 (FIG. FIG. 2 ), corresponding to the crossing of an axis, generate a signal 36.
- the signal 36 is applied via a signal terminal 28 to a - not shown - signal line.

Using suitable software, it is determined from the received signals how many axes are moved in or out of a track section. It is also determined with which speed these axes have retracted and whether individual axes have reversed and have returned. From the information is further - depending on the application - determined by what types of vehicles and how many vehicles had frequented the section at what time (track 44). In particular, the duration of stay in some sections of track is also recorded. The information gathered in this way promptly provides the condition of the track sections, thus enabling a reality-based billing of the infrastructure manager.
- the device is simple and can be retrofitted at virtually any point. A special device on the overrunning railway vehicles is not required.

- (a) einen Sensor zur Erfassung der Überfahrt einer Fahrzeugachse und Erzeugung von Überfahrtsignalen; und
- (b) Übertragungsmittel mit einem Modul zur drahtlosen Datenfernübertragung zum Übertragen der Überfahrtsignale an eine entfernt liegende Auswerteeinheit;

- (A) a sensor for detecting the crossing of a vehicle axle and generation of crossing signals; and
- (B) transmission means with a module for wireless remote data transmission for transmitting the crossing signals to a remote evaluation unit;
- (C) a second sensor for detecting the malfunction of a vehicle axle, which is arranged in spaced from the first sensor longitudinal direction of the track; and

Bei den Eisenbahnen sind Abstell- und Rangiergleise ein knappes Gut. Sowohl Infrastrukturbetreiber, als auch Verkehrsunternehmen versuchen daher, die vorhandenen Gleisanlagen so gut wie möglich auszunutzen. Es besteht ein permanentes Informationsbedürfnis über die Anzahl der aktuell auf einem Gleis tatsächlich abgestellten Fahrzeuge und der Belegungsveränderung. Der Infrastrukturbetreiber auf der einen Seite kann derzeit technisch nur ermitteln, ob ein Gleis belegt ist oder nicht. Aber nur wenige Abstell- und Rangiergleise sind an ein Stellwerk angebunden und verfügen über eine solche Einrichtung. Die Verkehrsunternehmen auf der anderen Seite führen manuelle Listen oder pflegen unterstützt durch eine Dispositionssoftware einen buchmäßigen, d.h. theoretischen Gleisspiegel.At the railways, parking and shunting tracks are a scarce commodity. Both infrastructure managers and transport companies are therefore trying to make the best possible use of the existing track systems. There is a constant need for information on the number of vehicles actually parked on a track and the change in occupancy. The infrastructure manager on the one hand can currently only technically determine whether a track is occupied or not. But only a few parking and Rangiergleise are connected to a signal box and have such a facility. The transport companies on the other hand maintain manual lists or, assisted by a scheduling software, maintain a book-like, i. theoretical track mirror.
Der Zustand eines Gleisabschnitts, insbesondere die Belegung, wird üblicherweise durch Personal ohne weitere technische Hilfsmittel ermittelt. Buchmäßige, d.h. theoretische Gleisspiegel können mit Hilfe eines Dispositionssystems erstellt werden. Dabei werden die Wagen elektronisch durch Rangieraufträge von einem Gleis zum anderen umgesetzt.The condition of a track section, in particular the occupancy, is usually determined by personnel without further technical aids. Accounting, ie theoretical track mirrors can be created using a disposition system. The cars are electronically converted by shunting from one track to another.
Ein Abgleich mit den in der Realität erfolgten Bewegungen insbesondere auch von Triebfahrzeugen erfolgt jedoch nicht. Auch werden keine Zwischenzustände oder hilfsweise genutzte Gleise erfasst.A comparison with the movements made in reality, especially of traction vehicles is not. Also, no intermediate states or auxiliary tracks are recorded.
Es sind sogenannte "Gleistore" bekannt. An einem Gleistor kann eine Markierung an den Fahrzeugen optisch oder über Funk erkannt werden. Hierzu werden beispielsweise RFID-Markierungen verwendet. Mit den Gleistoren kann der Gleiszustand fahrzeuggenau ermittelt werden. Dies erfordert jedoch, dass ein technisch aufwändiges optisches Erkennungs- und Auswertungssystem am Gleis installiert ist bzw. alle Fahrzeuge mit einer geeigneten Markierung versehen sind.There are so-called "Gleistore" known. On a Gleistor a mark on the vehicles can be recognized optically or by radio. For this example, RFID tags are used. With the Gleistoren the track condition can be determined vehicle-accurate. However, this requires that a technically complex optical recognition and evaluation system is installed on the track or all vehicles are provided with a suitable marking.
Es ist ferner bekannt, Fahrzeuge mit einem GPS-Ortungssystem auszustatten. Auch hier ist es erforderlich, alle Fahrzeuge nachzurüsten. Für eine gleis- und positionsgenaue Auflösung ist ferner eine sehr genaue Ortung vorzusehen, die zusätzliche technische Mittel, wie DGPS, erfordern.It is also known to equip vehicles with a GPS location system. Again, it is necessary to retrofit all vehicles. For a track and position accurate resolution is also a very accurate location provide that require additional technical means, such as DGPS.
Es sind sogenannte Achszähler bekannt. Die Achszähler werden in stellwerksbedienten Bereichen eingesetzt. Dabei wird die Achsenzahl dem Bedienpersonal meistens nicht und Verkehrsunternehmen überhaupt nicht dargestellt.There are known as axle counters. The axle counters are used in interlocking-operated areas. The number of axes is usually not the operator and transport companies not shown.
Um den letzten Achsdurchgang zu erkennen, wird eine Erwartungszeitspanne auf Grundlage der Geschwindigkeit berechnet. Beim Rangieren, bei dem die Fahrzeuggruppe auch auf dem Zählpunkt stehen bleiben könnte, versagt das Verfahren. Es ist nur dazu geeignet, eine Frei- oder Besetztmeldung für Fahrten mit nahezu konstanter Geschwindigkeit zu erzeugen, nicht aber den wirklichen Grad der Belegung abzubilden.
To detect the last axis passage, an expectancy period is calculated based on the speed. When maneuvering, where the vehicle group could also stop at the metering point, the procedure fails. It is only suitable for generating a free or busy message for trips with almost constant speed, but not to represent the actual degree of occupancy.
Der Hauptzweck bekannter technischer Einrichtungen ist die Sicherung des Fahrwegs und die Freigabe eines Gleises für eine Fahrt. Das bedeutet, es wird lediglich ein Signal erzeugt, welches angibt, ob sich ein Fahrzeug auf dem Gleis befindet.
Es ist Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, die auf einfache und kostengünstige Weise den Zustand von Gleisabschnitten ermitteln.It is an object of the invention to provide a device of the type mentioned, which determine the condition of track sections in a simple and cost-effective manner.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst. Anders als bei bekannten Achszählanordnungen wird hier nicht nur die Überfahrt einer Fahrzeugachse ermittelt, sondern auch unmittelbar die Richtung. Es kann also sehr genau festgestellt werden, wie viele Achsen die Sensoren tatsächlich passiert haben. Da die Vorrichtung keine Gleisfreigabe erteilt, sondern lediglich die Überfahrt ermittelt, sind keine zusätzlichen Sicherungen erforderlich. Entsprechend ist die Vorrichtung kostengünstig zu verwirklichen.According to the invention the object is achieved by the features of claim 1. Unlike known Achszählanordnungen not only the crossing of a vehicle axle is determined here, but also directly the direction. So it can be very accurately determined how many axes the sensors actually happened. Since the device does not give track approval, but only determines the crossing, no additional backups are required. Accordingly, the device is inexpensive to implement.
In einer bevorzugten Ausgestaltung der Erfindung umfassen die Übertragungsmittel ein GSM-Modul. Die Auswerteeinheit kann ein entfernter Server sein, der Daten einer Vielzahl von erfindungsgemäßen Vorrichtungen erhält. Die Übertragungsmittel übertragen dabei die "Rohdaten". Dadurch wird eine aufwändige Logik vor Ort vermieden. Die Daten werden unmittelbar übertragen. Es ist nicht erforderlich die vollständige Durchfahrt aller Fahrzeuge abzuwarten und entsprechende Zeitverzögerungen vor der Übertragung einzubauen.In a preferred embodiment of the invention, the transmission means comprise a GSM module. The evaluation unit can be a remote server which receives data from a multiplicity of devices according to the invention. The transmission means transmit the "raw data". This avoids complex on-site logic. The data is transmitted immediately. It is not necessary to wait for the complete passage of all vehicles and to install corresponding time delays before transmission.
Die Verwendung einer drahtlosen Datenfernübertragung hat den Vorteil, dass die erfindungsgemäße Vorrichtung vollständig autark ist. Sie kann an jeder quasi beliebigen Stelle am Gleis montiert werden. Sie ist einfach zu verschicken und sofort betriebsbereit. Es ist keine aufwändige elektronische Einrichtung oder Softwareinstallation erforderlich. Die Daten können mit einer Kennung verschickt werden, der die Position, beispielsweise in der Auswerteeinheit zugeordnet ist.The use of a wireless remote data transmission has the advantage that the device according to the invention is completely self-sufficient. It can be mounted anywhere on the track. It is easy to send and ready to use. There is no time-consuming electronic device or software installation required. The data can be sent with an identifier, which is assigned to the position, for example in the evaluation unit.
Bei der Erfindung sind die Sensoren und die Übertragungsmittel auf einer gemeinsamen Basisplatte befestigt. Dabei kann ein Teil der Basisplatte unter der Schiene geordnet sein und die Sensoren können auf einer Seite der Schiene und die Übertragungsmittel auf der anderen Seite der Schiene auf der Basisplatte befestigt sein. Bei Verwendung von Schraubbefestigungen mit gesicherten Schrauben sind Spezialwerkzeuge zum Lösen erforderlich. Dann ist die Anordnung für Unbefugte praktisch nicht entfernbar. Die Übertragungsmittel und sonstige evtl. erforderliche elektronische und elektrische Bauteile können in einem staub- und wasserdichten, temperaturbeständigen Gehäuse angeordnet sein, so dass empfindliche Komponenten vor Umwelteinflüssen geschützt sind. Hier ist beispielsweise die Schutzklasse IP 67 geeignet.In the invention, the sensors and the transmission means are mounted on a common base plate. In this case, a part of the base plate may be arranged below the rail and the sensors may be fastened on one side of the rail and the transmission means on the other side of the rail on the base plate. When using screw fasteners with secured screws, special tools are required for loosening. Then the arrangement is practically not removable for unauthorized persons. The transmission means and other possibly required electronic and electrical components can be arranged in a dustproof and watertight, temperature-resistant housing, so that sensitive components are protected against environmental influences. Here, for example, the protection class IP 67 is suitable.
Vorzugsweise sind die Sensoren an einem höhenverstellbaren Halter befestigt. Dann kann die erfindungsgemäße Vorrichtung für Schienen unterschiedlicher Höhe, Bauart oder Abnutzung verwendet werden.Preferably, the sensors are attached to a height-adjustable holder. Then the device according to the invention can be used for rails of different heights, design or wear.
Bei einer besonders bevorzugten Ausgestaltung der Erfindung sind ein Solarmodul mit wiederaufladbaren Akkumulatoren, Batterien oder eine andere autarke Energieversorgung für die Sensoren und/oder die Übertragungsmittel vorgesehen. Dadurch ist die erfindungsgemäße Vorrichtung autark und braucht an keine Strom- oder sonstige Datennetze angeschlossen werden. Insbesondere ein Solarmodul vermeidet hohen Wartungsaufwand, wie etwa den Wechsel von Batterien.In a particularly preferred embodiment of the invention, a solar module with rechargeable batteries, batteries or another self-sufficient energy supply for the sensors and / or the transmission means are provided. As a result, the device according to the invention is self-sufficient and does not need to be connected to any power or other data networks. In particular, a solar module avoids high maintenance, such as the replacement of batteries.
Die erfindungsgemäße Vorrichtung kann mit einem Verfahren gemäß Anspruch 6 betrieben werden. Dabei kann insbesondere auch erfasst werden, wenn ein Fahrzeug mit einer Achse zwischen den Sensoren stehenbleibt. Eine Überfahrt in Richtung von Sensor 1 nach Sensor 2 erzeugt folgende Signalabfolge:
Fährt die Achse in der entgegengesetzten Richtung, sind Schritt B und D vertauscht. Aus der Reihenfolge der Überfahrtsignale der Sensoren wird so die Fahrtrichtung des Fahrzeugs ermittelt. Zudem wird erfindungsgemäß eine Überfahrt verifiziert. Falsche Signale an einem der beiden Sensoren werden leicht als solche identifiziert, wenn die zugehörigen Signale am anderen Sensor nicht erzeugt werden.If the axis is traveling in the opposite direction, steps B and D are reversed. From the sequence of the crossing signals of the sensors so the direction of travel of the vehicle is determined. In addition, a crossing is verified according to the invention. Incorrect signals on one of the two sensors are easily identified as such if the associated signals are not generated on the other sensor.
Aus dem zeitlichen Abstand zwischen Schritt B und Schritt D kann zusätzlich die Geschwindigkeit der Achse bestimmt werden. Hierzu kann der Zeitpunkt der Überfahrt einer Fahrzeugachse über den Sensoren oder der zeitliche Abstand der Überfahrt zwischen den Sensoren ermittelt und an die Auswerteeinheit übertragen werden. Weiterhin kann der Abstand der Sensoren in Längsrichtung an die Auswerteeinheit übertragen werden oder in der Auswerteeinheit gespeichert sein und aus dem Abstand der Sensoren und der zeitlichen Differenz zwischen den Überfahrtsignalen einer Fahrzeugachse die Fahrzeuggeschwindigkeit ermittelt werden.From the time interval between step B and step D, the speed of the axis can additionally be determined. For this purpose, the time of crossing a vehicle axle via the sensors or the time interval of the crossing between the sensors can be determined and transmitted to the evaluation unit. Furthermore, the distance of the sensors in the longitudinal direction can be transmitted to the evaluation unit or stored in the evaluation unit and the vehicle speed can be determined from the distance between the sensors and the time difference between the crossing signals of a vehicle axle.
