Abstract

A diagnosis device for a wheel set for monitoring railway vehicles passing by is described, which is characterised in that a cavity which extends parallel to the sleeper is provided in a measuring sleeper or in a hollow track sleeper (11), in which cavity IR deflection units and at least one IR reception unit (15) are accommodated, which units permit, in contrast with previously known technologies, all the heat sources present in the region of the wheel set and on the underside of the vehicle to be monitored and, at the same time, provide the greatest possible degree of protection against mechanical and electrical influences. The wheel pressure and acceleration measuring devices which were first introduced in conjunction with the invented wheel set diagnosis device permit precise determination of the variables, such as wheel position, wheel weight and tread quality of the wheel, which are absolutely necessary to relativise the IR measurement results. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zur Temperaturerfassung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for temperature detection according to the preamble of claim 1.

Zu diesem Zwecke sind bei nahezu allen Bahnverwaltungen Infrarotmeßsysteme eingesetzt, die auf Betonfundamenten oder an den Schwellen oder an den Schienen befestigt sind und aus Gründen der Freihaltung des Freiraumprofils außerhalb des Raumes zwischen den beiden Schienen befestigt werden müssen. Zwei Schienen plus den Schwellen bilden dabei das Gleis.For this purpose, almost all railway administrations Infrared measuring systems used on Concrete foundations or on the sleepers or on the Rails are attached and for reasons of freedom of the free space profile outside the space between the two rails must be attached. This is formed by two rails plus the sleepers Track.

Alle diese bekannten Einrichtungen haben gravierende Nachteile bezüglich der notwendigen Anzahl von Gleisschalteinrichtungen, der zwangsläufig aufwendigen Befestigungen, der mechanischen und elektrischen Beeinflußbarkeit, der Konstanz der Meßgeometrie, der mit einer Anordnung pro Achse überwachbaren Radsatz- bzw. Fahrzeugelemente und der elektrischen Sicherheit bezüglich des Berührungsschutzes gegen lebensgefährdende elektrische Spannungen an den Gehäusen der Abtasteinrichtungen.All of these known devices have serious ones Disadvantages regarding the necessary number of Track switching devices, the inevitably expensive Fastenings, mechanical and electrical Influenceability, the constancy of the measurement geometry, the with a set of axles that can be monitored per axle or vehicle elements and the electrical Safety with regard to protection against contact life-threatening electrical voltages at the Housings of the scanning devices.

Bei den herkömmlichen Meßsystemen müssen zur Überwachung von Einrichtungen, die zwischen den Laufrädern eines Radsatzes angeordnet sind, Meßgeometrien eingesetzt werden, deren Inklinationswinkel > 90° beträgt. Diese Anordnungen erfordern mindestens ein zusätzliches Gleisschaltmittel zur Eingrenzung des Meßbereiches. Zudem können die festgelegten Meßstellen nur erreicht werden, wen z.B. Magnetschienen- oder Wirbelstrombremsen nicht abgesenkt, d.h. nicht in Bremsstellung sind.In the conventional measuring systems Monitoring facilities between the Wheels of a wheel set are arranged, measuring geometries are used whose inclination angle> Is 90 °. These orders require at least an additional track switching device to limit the Measuring range. In addition, the specified measuring points can only be reached, e.g. Magnetic track or eddy current brakes not lowered, i.e. not in Are braking position.

Außerdem ist ein direkter Einfall des Sonnenlichtes in derartige Anordnungen bei tiefstehender Sonne möglich und führt zu Fehlalarmen während der Zugfahrten.There is also a direct incidence of sunlight in such arrangements possible when the sun is low and leads to false alarms during train journeys.

Die Befestigung der Meßsysteme an Schiene, Schwelle oder auf Betonfundamenten ist wegen des relativ hohen Gewichtes, von bis zu 50 kg, extrem aufwendig. Die mechanische Beeinflussung der schienen-bzw. schwellenbefestigten Einrichtungen führt zu häufigen Systemstörungen und damit zu einer Verringerung der Verfügbarkeit und zu einer Erhöhung der Instandhaltungsaufwendungen.The fastening of the measuring systems to the rail, Threshold or on concrete foundations is because of the relatively high weight, up to 50 kg, extremely expensive. The mechanical influencing of the rail or threshold-fixed facilities lead to frequent System malfunctions and thus a reduction availability and an increase in maintenance expenses.

Die Meßgeometrie der Abtastsysteme kann sich bei derartigen Anordnungen durch Vibration oder mechanische Schläge, z.B. durch herabhängende Fahrzeug- und/oder Ladungsteile unbemerkt verändern, was zu erheblichen Betriebsgefährungen führen kann. Zum Schutze der Abtastsysteme müssen daher Abweisbleche installiert werden, die den Instandhaltungsaufwand erheblich erhöhen. Die Kabelverbindungen werden bei diesen Aufbauten üblicherweise auf dem Oberbau verlegt, um auch bei gefrorenem Boden einen Kabelaus tausch zu ermöglichen. Beschädigungen an diesen elektrischen Verbindungen sind daher relativ häufig.The measuring geometry of the scanning systems can be such arrangements by vibration or mechanical Blows, e.g. by drooping vehicle and / or load parts change unnoticed what to significant operational risks. To the Protection of the scanning systems must therefore deflector plates be installed, the maintenance effort increase significantly. The cable connections are at these superstructures are usually laid on the superstructure, in order to avoid cables even when the ground is frozen to enable exchange. Damage to this electrical connections are therefore relatively common.

Die elektrische Sicherheit gegen unzulässig hohe Berührungsspannungen kann bei den bislang eingesetzten schienenbefestigten Meßsystemen, die mit 220 V versorgt werden, und bei Trassen, die mit Gleiskreisfreimeldung ausgestattet sind, nur durch die elektrische Verbindung eines Abtasters mit der jeweiligen Schiene realisiert werden. Bei abgelöster Erdverbindung und spannungsführendem Infrarotabtastergehäuse kann für das Instandhaltungspersonal Lebensgefahr bestehen.Electrical safety against impermissibly high levels Touch voltages can be used in the previously used rail-mounted measuring systems with 220 V are supplied, and for routes that have track circuit free notification are equipped only by the electrical Connection of a scanner to the respective rail will be realized. When the earth connection is disconnected and Live infrared scanner housing can be used for the maintenance personnel are at risk of death.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu überwinden und eine Einrichtung anzugeben, mit der jedes beliebige Radsatz- und/oder Fahrzeugteil mit der kürzestmöglichen Meßstrecke überwacht werden kann, deren Meßsysteme an jeder Stelle parallel zur Schwelle, also auch zwischen den Schienen, angeordnet werden können, deren Meßgeometrien unveränderbar und deren Meßsysteme weder mechanisch noch elektrisch beeinflußbar sind.The invention is based on the object Overcome disadvantages and specify a facility with the any wheelset and / or vehicle part with the shortest possible measuring distance can be monitored, their measuring systems at each Place parallel to the threshold, i.e. also between the Rails can be arranged, their measurement geometries unchangeable and their measuring systems neither are mechanically influenced electrically.

Diese Aufgabe ist durch eine Einrichtung gelöst, welche die in Anspruch 1 angegebenen Merkmale aufweist. Die erfindungsgemäße Einrichtung zeichnet sich dadurch aus, daß durch geeignet angeordnete Umlenkeinheiten die einzelnen infrarotquellen eines jeden Fahrzeugs und/oder Radsatzes mehrfach parallel abgetastet werden und die Infrarotstrahlung insgesamt parallel einer oder mehreren Infrarotempfängereinheiten zugeführt wird.This task is solved by a facility which has the features specified in claim 1. The device according to the invention stands out characterized in that by suitably arranged deflection units the individual infrared sources of each vehicle and / or wheel set scanned several times in parallel and the infrared radiation in total in parallel fed to one or more infrared receiver units becomes.

Die Einrichtung ist in einer Hohlgleisschwelle untergebracht die parallel zu den Gleisschwellen angeordnet ist.The device is housed in a hollow track sleeper in parallel is arranged to the track sleepers.

Die einzelnen Umlenkeinheiten sind mit einer oder mehreren Verschlußeinheiten ausgestattet, durch welche die Infrarotstrahlung in die Umlenkeinheit gelangt. Durch letztere kann die Infrarotstrahlung umgelenkt und/oder getaktet und/oder ausgeblendet werden.The individual deflection units are with or equipped with several locking units, through which the infrared radiation reaches the deflection unit. The infrared radiation can be deflected by the latter and / or clocked and / or hidden.

Die in der Hohlgleisschwelle angeordnete Infrarotempfangseinheit kann mehrere Signale empfangen und gegebenenfalls miteinander verknüpfen. Durch den relativ großen Abstand zu den Schienen sowie auf Grund der elektrischen Abschirmung durch das tragende Metallprofil ist die elektromagnetische Beeinflussung dieser Empfangseinheit auf ein Minimum reduziert. Alle Versorgungs- und Datenleitungen sind durch das Metallprofil elektrisch und mechanisch geschützt.The one in the hollow track sleeper arranged infrared receiving unit can receive multiple signals and if necessary link together. Due to the relatively large Distance to the rails and due to the electrical Shielding by the supporting metal profile is the electromagnetic influence of this receiving unit reduced to a minimum. All supply and data lines are through the Metal profile electrically and mechanically protected.

Durch die im Bereich der Schwelle an der Schiene installierten Einrichtungen zur Erfassung des Radauflagedruckes und der Beschleunigung der Schiene bzw. der Schwelle in Richtung senkrecht zur Schienenlängsachse kann die genaue Radposition ermittelt und somit der Meßbereich parallel zur Gleisachse von Ache zu Achse ermittelt und eingestellt und die Meßwerte in einer nachgeschalteten Auswerteeinheit ggf. korrigiert werden. By in the area of the threshold on the rail installed devices for recording the wheel support pressure and the acceleration of the rail or the threshold in the direction perpendicular to the longitudinal axis of the rail can determine the exact wheel position and thus the measuring range parallel to the track axis from Ache Axis determined and set and the measured values in one downstream evaluation unit may be corrected.

An der Auswerteeinheit stehen somit die Temperaturwerte aller Radsatzkomponenten und diverser Fahrzeugkomponenten, das Radsatzgewicht insgesamt, sowie die Radlasten zur Verfügung.The temperature values are thus on the evaluation unit all wheelset components and various vehicle components, total wheelset weight, as well as the wheel loads available.

Im Zusammenhang mit den Beschleunigungswerten und dem Raddruck stehen Meßgrößen zur Verfügung, die auch auf den Zustand des Rades in Bezug auf Unwuchten und Laufflächenschäden, die eine Ursache für Lagerschäden sind, Aufschluß geben.In connection with the acceleration values and the wheel pressure, measurement variables are available, which is also related to the condition of the wheel Imbalance and tread damage, which is a cause for bearing damage, provide information.
