Schaltungsanordnung zum Prüfen von AchszähleinrichtungenCircuit arrangement for testing axle counting devices
Die Erfindung betrifft eine Schaltungsanordnung mit einer Batterie zum Prüfen von Achszähleinrichtungen im Eisenbahnbetrieb.The invention relates to a circuit arrangement with a battery for testing axle counting devices in railway operations.
Insbesondere bei älteren Achszählanlagen kommt es zu Störungen sowohl in den Außenanlagen als auch in den Innenanlagen, die dann Verzögerungen im Eisenbahnbetrieb verursachen. Die Gründe hierfür liegen u.a. an den in den letzten 20 Jahren geänderten Einsatzbedingungen. Hierzu zählen u.a. die verstärkte mechanische Beanspruchung durch Erhöhung der Zuggeschwindigkeiten, die erhöhten Störeinkopplungen durch größere Antriebsleistungen und der Einsatz der Magnetschienenbremse. Bei den Außenanlagen kommen noch Alterungserscheinungen und Temperatureinflüsse hinzu.Older axle counting systems in particular are prone to malfunctions in both the external and internal systems, which then cause delays in rail operations. The reasons for this include the changed operating conditions over the last 20 years. These include the increased mechanical stress caused by increased train speeds, the increased interference caused by higher drive power and the use of magnetic rail brakes. In the case of external systems, signs of aging and temperature influences also come into play.
Um die Störungen an den unterschiedlichen Bauarten einzugrenzen sind bisher Sonderzugfahrten erforderlich gewesen. Dieses Verfahren ist sehr zeit- und kostenaufwendig gewesen. Aufgabe der Erfindung ist es, eine Möglichkeit zu finden, um die zusätzlichen Zugfahrten zu vermeiden und die Störung in kürzester Zeit zu erkennen.In order to limit the faults in the different types of construction, special train journeys have previously been necessary. This process was very time-consuming and costly. The aim of the invention is to find a way to avoid the additional train journeys and to detect the fault in the shortest possible time.
Erfindungsgemäß wird diese Aufgabe gelöst mit einer Schaltungsanordnung, die dadurch gekennzeichnet ist, daß mittels einer Tastatur vorgegebene Daten in einer Mikrocontrollereinheit speicherbar sind und analoge Impulse an eine Induktionsspule übertragbar sind.According to the invention, this object is achieved with a circuit arrangement which is characterized in that predetermined data can be stored in a microcontroller unit by means of a keyboard and analog pulses can be transmitted to an induction coil.
Bei Verwendung einer derartigen Schaltungsanordnung werden nicht nur Kosten für zusätzliche Zugfahrten vermieden, sondern die Störungen können auch kurzfristig und schnell eingegrenzt und anschließend beseitigt werden.Using such a circuit arrangement not only avoids costs for additional train journeys, but also allows the disruptions to be quickly and quickly contained and then eliminated.
Zweckmäßige Ausgestaltungen sind in den Schutzansprüchen 2 bis 6 angegeben, wobei die Verwendung eines tragbaren Koffers den Einsatz der Erfindung vereinfacht.Appropriate embodiments are specified in claims 2 to 6, whereby the use of a portable case simplifies the use of the invention.
Ein Ausführungsbeispiel wird anhand der in Figur 1 dargestellten Prinzipschaltung beschrieben.An embodiment is described using the basic circuit shown in Figure 1.
Zum Prüfen der Außenanlage wird die Spule 3 auf die Schiene 10 in Höhe des Achszählpunktes 11 gelegt. Mit der Tastatur 1 des mit der Spule 3 verbundenen Koffers 9 wird zunächst die gewünschte Funktion (Zählimpulse, Achsabstand) gewählt und anschließend werden die Zugdaten Achszahl und Geschwindigkeit sowie die Fahrrichtung eingegeben. Mit einer besonderen Taste wird dann die Simulation der Zugfahrt gestartet. Entsprechend den Einstellungen wird dabei die Spule 3 taktweise kurzgeschlossen. Die Frequenz wird vom Impulsgeber 7 bestimmt. Jeder Kurzschluß simuliert am Zählpunkt 11 die Vorbeifahrt einer Achse.To test the external system, coil 3 is placed on rail 10 at the height of axle counting point 11. Using keyboard 1 of the case 9 connected to coil 3, the desired function (counting pulses, axle spacing) is first selected and then the train data, number of axles and speed, as well as the direction of travel, are entered. The simulation of the train journey is then started using a special button. According to the settings, coil 3 is short-circuited in cycles. The frequency is determined by pulse generator 7. Each short circuit simulates the passing of an axle at counting point 11.
Da die Prüfung nur bei exakter Batteriespannung einwandfrei funktioniert, wird die Batterie 5 durch eine besondere Überwachung 6 laufend überwacht. Bei Unterschreitung des eingestellten Spannungswertes wird dies durch den Signalgeber 8 aktualisiert und auf dem Display 4 optisch angezeigt.Since the test only works properly when the battery voltage is exact, the battery 5 is continuously monitored by a special monitoring device 6. If the set voltage value is undershot, this is updated by the signal generator 8 and visually indicated on the display 4.
