Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Überwachung der Temperatur der Radsatzlager von vorbeifahrenden Schienenfahrzeugen, bestehend aus mindestens einer unterhalb des Schienenstranges in einem Gehäuse befindlichen und an eine Auswerteinheit angeschlossene IR-Empfangseinheit, wobei das Gehäuse sich über mindestens zwei Dämpfungsglieder abstützend in eine Schwelle eingesetzt ist.The The invention relates to a device for monitoring the temperature of Wheelset bearings of passing rail vehicles, consisting of at least one located below the rail track in a housing and to an evaluation unit connected IR receiving unit, wherein the housing over at least two attenuators supportively is used in a threshold.
Es ist bekannt, die Temperatur von Radsatzlagern an Schienenfahrzeugen, insbesondere an Eisenbahnfahrzeugen, zu überwachen, um sogenannte Heißläufer-Entgleisungen zu vermeiden. Dazu werden von den Bahnverwaltungen IR-Messsysteme mit mindestens einer IR-Empfangseinheit eingesetzt, die sich unterhalb des Schienenstranges befindet und meist in einer besonders ausgebildeten Messschwelle oder einer Hohlschwelle untergebracht ist. Meistens sind jedoch in einer solchen Schwelle vier IR-Empfangseinheiten vorgesehen, über die die Temperaturen aller Radsatzlager eines Radsatzes erfasst werden können. Die dabei ermittelten Werte werden normalerweise mit den Werten bzw. Infrarotsignalmustern verglichen, die in einer Auswerteinheit, beispielsweise einem Rechner, abgespeichert sind. Bei unzulässigen Abweichungen wird ein Alarmsignal abgegeben. Um diese IR-Empfangseinheiten gegen äußere Einflüsse zu schützen, sind dieselben jeweils in verschließbaren Gehäusen untergebracht, die in die Mess- bzw. Hohlschwelle eingesetzt sind. Diese Gehäuse werden allerdings nicht direkt, sondern über jeweils mindestens zwei Dämpfungsglieder mit der Mess- bzw. Hohlschwelle verbunden, die aus Gummi, Kunststoff bestehen können oder durch Stahlfedern gebildet sind und einen Hub von etwa 2 bis 4 mm aufweisen. Dadurch wird vermieden, dass die Schwingungen, die immer beim Überfahren eines Radsatzes über die Mess- bzw. Hohlschwelle entstehen, nicht bzw. nur in geringem Maße auf die IR-Empfangseinheiten übertragen werden, die empfindliche Bauteile sind und die durch diese Schwingungen beschädigt oder zerstört werden können.It is known, the temperature of wheelset bearings on rail vehicles, especially on railway vehicles, to monitor so-called hot-runner derailments to avoid. To this end, the rail authorities will be using IR measuring systems at least one IR receiver unit used, which is located below the rail track and usually in a specially trained measuring threshold or a hollow threshold is housed. Mostly, however, are in such a threshold provided four IR receiving units, over which the temperatures of all Wheelset bearing of a wheelset can be detected. The determined Values are usually taken with the values or infrared signal patterns compared in an evaluation unit, for example a computer, are stored. Inadmissible Deviations an alarm signal is issued. To these IR receiving units to protect against external influences are the same each in lockable housings housed, which are used in the measuring or hollow threshold. This case but not directly, but over at least two attenuators connected to the measuring or hollow threshold made of rubber, plastic can exist or are formed by steel springs and a stroke of about 2 to 4 mm. This avoids that the vibrations, the always when driving over one Wheelset over the measuring or hollow threshold arise, not or only in small Dimensions on transmit the IR receiver units which are sensitive components and which are caused by these vibrations damaged or destroyed can be.
Derzeit werden die IR-Empfangseinheiten etwa alle 6 Monate auf ihre richtige Funktionsweise überprüft. Im Hinblick auf defekte Schwingungsdämpfer kann dieser Zeitraum eindeutig zu lang sein. Defekte an den Schwingungsdämpfern können bereits vor dem Einbau vorhanden sein oder aber auch schon beim Einbau oder zu einem späteren Zeitpunkt auftreten. Ein fehlerhafter Schwingungsdämpfer bringt jedoch die Gefahr mit sich, dass die zugeordnete IR-Empfangseinheit gelegentlich über einen kürzeren oder längeren Zeitraum ausfällt, ohne dass die eigentliche Ursache erkannt werden kann. Dies kann dann zu einer Beschädigung oder Zerstörung der IR-Empfangseinheit und/oder zu fehlerhaften Messergebnissen führen.Currently The IR receiver units will be set to their correct one about every 6 months Functionality checked. In terms of on defective vibration absorbers this period can clearly be too long. Defects on the vibration dampers can already be present before installation or even during installation or for a later Time occur. A faulty vibration damper brings however, there is a risk that the associated IR receiving unit occasionally has a shorter or shorter period of time longer Period fails, without the actual cause can be detected. This can then to damage or destruction of IR receiver unit and / or lead to incorrect measurement results.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zur Überwachung der Temperatur der Radsatzlager von vorbeifahrenden Schienenfahrzeugen so auszugestalten, dass ein defekter bzw. nicht einwandfrei arbeitender Schwingungsdämpfer sofort erkannt werden kann und somit eine Beschädigung oder Zerstörung der IR-Empfangseinheit ausgeschlossen und daraus resultierende fehlerhafte Messergebnisse vermieden werden.Of the The invention is therefore based on the object, a device for monitoring the temperature of the wheelset bearings of passing rail vehicles in such a way that a defective or not working properly vibration can be detected immediately and thus damage or destruction of IR receiver unit excluded and resulting erroneous measurement results be avoided.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung bei einer Vorrichtung zur Überwachung der Temperatur der Radsatzlager von vorbeifahrenden Schienenfahrzeugen der eingangs genannten Art vorgeschlagen, dass dem Gehäuse ein ebenfalls an die Auswerteinheit angeschlossener Beschleunigungssensor zugeordnet ist.to solution This object is achieved according to the invention in a device for monitoring the temperature of the wheelset bearings of passing rail vehicles of the type mentioned above proposed that the housing also connected to the evaluation unit accelerometer assigned.
Durch den zusätzlichen, dem Gehäuse zugeordneten Beschleunigungssensors ist es möglich, fehlerhafte Schwingungsdämpfer sofort zu erkennen, indem die gemessenen Beschleunigungswerte mit den in der Auswerteinheit gespeicherten Werten verglichen und unzulässige Abweichungen sofort als Alarmsignal einer Überwachungszentrale mitgeteilt werden.By the additional, the housing associated acceleration sensor, it is possible faulty vibration damper immediately be recognized by the measured acceleration values with in the Evaluation unit stored values compared and impermissible deviations immediately as an alarm signal from a monitoring center be communicated.
Der Beschleunigungssensor kann dabei entweder im Gehäuse oder am Gehäuse angeordnet sein.Of the Acceleration sensor can be arranged either in the housing or on the housing.
