Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Datenübertragung von einem Schienenfahrzeug an eine Abfrageeinrichtung im Nahbereich derselben mittels passiver Transponder sowie Elementen zur Befestigung von Transpondern an im wesentlichen zylindrischen Bauteilen.The invention relates to a device for data transmission from a rail vehicle to an interrogation device in the vicinity of the same by means of passive transponders and elements for fastening transponders to essentially cylindrical ones Components.
Für Betreiber von Schienenverkehrsfahrzeugen ist es von grosser Wichtigkeit, jederzeit
einen Überblick über die im Betriebseinsatz befindlichen Radsätze zu haben. Insbesondere
bei der regelmässigen Erfassung von Radparametern (z.B. beim Überprüfen des
Verschleisszustandes eines Rades) ist eine schnelle und zweifelsfreie Identifizierung
des Radsatzes von Bedeutung.
Bislang geschieht dies üblicherweise über eine Identifizierungsnummer, die auf einem
die Achse des Radsatzes umfassenden Stahlband eingraviert bzw. mittels Schlagwerkzeugen
eingeprägt ist und optisch abgelesen wird. Dies erweist sich in der Praxis immer
wieder als nachteilig, da die Stahlbänder aufgrund der herrschenden Betriebsbedingungen
stets stark verschmutzt sind und erst gesäubert werden müssen, damit ein Ablesen
der Identifikationsnummer erst möglich wird. Ebenso ist es nachteilig, dass die Radsätze
zum Zeitpunkt des Ablesevorganges nicht notwendigerweise eine günstige Position
hinsichtlich der optischen Ablesbarkeit durch das Instandhaltungspersonal einnehmen.
Wenn das Stahlband nicht manuell in eine brauchbare Ablese-Position verdreht werden
kann, müsste im Extremfall der Radsatz als ganzes gedreht werden, was in Bezug auf
den eigentlich sehr kurzen Ablesevorgang bei weitem zu zeitaufwendig ist. Zudem fallen
die Stahlbänder beim Versuch eines manuellen Verdrehens immer wieder ab, da sie
zum einen wegen Verschmutzung oder Alterung fest sitzen und zum anderen einer
Materialermüdung unterliegen.
Zur Behebung dieser Nachteile sowie zur Automatisierung der Radsatz-ldentifikation
sind bereits einige Vorschläge zur Nutzung von Transpondern bekannt geworden.
So lehrt DE 297 20 652 beispielsweise eine elektromagnetische Reflexionseinrichtung
zur automatischen Identifizierung von Schienenfahrzeugen, deren Radsätze eine zur
Gleismitte hin fest beabstandete Haltevorrichtung zur Aufnahme eines mit einer Ringantenne
versehenen Transponders. Als entsprechende Haltevorrichtung wird eine
Spannschelle mit Spannschraube bzw. ein Spannband mit Spannschloss offenbart.
Dem Fachmann erschliesst es sich jedoch nicht, in welcher Weise diese Haltevorrichtung
nebst Transponder in Anbetracht der extremen Umwelteinflüsse und stark korrosiv
wirkenden Umgebungsbedingungen zur Erzielung einer wirtschaftlich akzeptablen Mindest-Dauerfestigkeit
ausgeführt werden sollen. It is very important for operators of rail vehicles to have an overview of the wheel sets in operation at all times. A quick and unequivocal identification of the wheel set is particularly important when regularly recording wheel parameters (eg when checking the wear condition of a wheel).
So far, this has usually been done using an identification number, which is engraved on a steel band encompassing the axle of the wheel set or stamped by means of striking tools and is optically read. In practice, this proves to be disadvantageous again and again because the steel strips are always very dirty due to the prevailing operating conditions and must first be cleaned so that the identification number can only be read off. It is also disadvantageous that the wheel sets do not necessarily occupy a favorable position in terms of visual readability by the maintenance personnel at the time of the reading process. If the steel band cannot be turned manually into a usable reading position, the wheel set as a whole would have to be turned in extreme cases, which is far too time-consuming in relation to the actually very short reading process. In addition, the steel straps keep falling off when you try to twist them manually, because on the one hand they are stuck due to dirt or aging and on the other hand they are subject to material fatigue.
In order to remedy these disadvantages and to automate the wheel set identification, some suggestions for using transponders have already become known.
For example, DE 297 20 652 teaches an electromagnetic reflection device for the automatic identification of rail vehicles, the wheel sets of which have a holding device which is fixedly spaced from the center of the track for receiving a transponder provided with a ring antenna. As a corresponding holding device, a clamp with a clamping screw or a strap with a turnbuckle is disclosed. However, it is not clear to the person skilled in the art how this holding device and transponder should be designed in view of the extreme environmental influences and strongly corrosive environmental conditions in order to achieve an economically acceptable minimum fatigue strength.
Aus DE 198 17 941 ist eine transponderbasierte Datenübertragungseinrichtung von
einem Schienenfahrzeug an eine Abfrageeinrichtung bekannt, deren Antenne die Achse
als Manschette über einen Winkel von 360° umfasst. Ein solcher technologischer Ansatz
ist zwar für automatisierte Auslesevorgänge geeignet; in der konkreten betrieblichen
Anwendung, die einen Einsatz im Massenbetrieb erfordert, hat sich eine derartige
Transpondervorrichtung jedoch als zu kostenintensiv herausgestellt. Auch die diesbezügliche
aus DE 198 47 291 bekannte Modifikation unter Verwendung zweier identischer
Antwortgeräte, von denen jedes mit mindestens einer die Achse partiell umschliessenden,
um 180° zueinander versetzt angeordneten Antenne zusammenwirkt,
kann die Probleme hinsichtlich einer kostengünstigen Herstellung nicht wirksam beseitigen.
Ein grundsätzliches Problem derartiger Systeme, die auf eine automatisierte Auslesung
der Identifikationsmerkmale hin ausgelegt sind, besteht ferner darin, dass zwischen der
streckenseitigen bzw. ortsfesten Auslesevorrichtung und der Radsatzwelle exakte Abstände
eingehalten werden müssen. Andernfalls sind keine nennenswerten Leseabstände
zu erreichen. Die Lesefähigkeit wird durch die bei Überfahrt des Radsatzes über
eine Auslesevorrichtung ausgeführte rotatorische und / oder translatorische Bewegung
negativ beeinflusst. Befinden sich während des Lesevorganges mehrere Transponder
im Lesefeld der Auslesevorrichtung, so kann eine eindeutige Identifizierung einzelner
Radsätze nicht mehr sichergestellt werden (mangelnde Bulkfähigkeit).DE 198 17 941 discloses a transponder-based data transmission device from a rail vehicle to an interrogation device, the antenna of which encompasses the axis as a sleeve over an angle of 360 °.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Datenübertragung von einem Schienenfahrzeug an eine Abfrageeinrichtung im Nahbereich derselben mittels passiver Transponder sowie Elementen zur Befestigung von Transpondern an im wesentlichen zylindrischen Bauteilen zu entwickeln, die eine hinsichtlich der einsatzbedingten hohen Belastungen und extremen Umgebungsbedingungen robuste und dauerhafte Konstruktion aufweist. Ihre Anwendung darf keine besonderen Fertigkeiten beim Bediener voraussetzen und muss mit geringem Handhabungsaufwand innerhalb sehr kuzer Zeiten ausführbar sein. Niedrige Anschaffungs- und Instandhaltungskosten sollen dafür sorgen, dass die Vorrichtung in grosser Anzahl an allen im Betrieb befindlichen Radsätzen zum Einsatz kommen kann.The invention has for its object a device for data transmission from a rail vehicle to an interrogation device in the vicinity thereof passive transponder and elements for attaching transponders to essentially develop cylindrical components, the one in terms of use high loads and extreme environmental conditions robust and durable Construction. Your application must not have any special skills in Operator presuppose and has to be handled with very little effort short times to be executable.

Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Schutzanspruches 1 erfindungsgemäß dadurch gelöst, dass der Transponder (1) und das Befestigungselement (2) mittels einer Kunststoffvergussmasse oder einer Kunststoffschrumpfmasse (3) formschlüssig miteinander verbunden sind und das so geschaffene Komposit kraftschlüssig an einer frei wählbaren Stelle einer Achse (4) des Schienenfahrzeuges angebracht ist.This object is achieved in connection with the preamble of protection claim 1 solved in that the transponder (1) and the fastening element (2) by means of a plastic casting compound or a plastic shrink compound (3) are interconnected and the composite created in this way is non-positive is attached to a freely selectable point on an axle (4) of the rail vehicle.
Der Erfindungsgedanke wird wirksam unterstützt, wenn der Transponder innerhalb der Verguss- bzw. Schrumpfmasse auf ein versteifend wirkendes Zwischenelement aufgebracht ist. Dadurch wird verhinder, dass der Transponder während des Schrumpfvorganges bzw. durch Schwundprozesse nach dem Vergiessen durch Deformation geschädigt wird.The inventive concept is effectively supported if the transponder is within the Casting or shrinking compound applied to a stiffening intermediate element is. This prevents the transponder from shrinking or damaged by shrinkage processes after casting through deformation becomes.
Es ist für den Erfindungsgegenstand von besonderem Vorteil, wenn der Transponder auf einer auf der Fahrzeugachse aufliegenden Schicht aus einem elastisch und / oder plastisch verformbaren Material zum Ausgleichen von Unebenheiten der Oberfläche der Fahrzeugachse und / oder zum Anpassen des Transponders an unterschiedliche Achsendurchmesser aufgebracht ist.It is of particular advantage for the subject matter of the invention if the transponder on a layer lying on the vehicle axle made of an elastic and / or plastically deformable material to compensate for unevenness in the surface of the Vehicle axle and / or to adapt the transponder to different axle diameters is applied.
Eine vorteilhafte Ausgestaltung des Erfindungsgedankens sieht vor dass der Tranponder in einem frei beschreibbarem Speicherbereich Daten zur eindeutigen Identifikation des Radsatzes enthält. Hierbei handelt es sich neben einer eindeutig zuscheidbaren Bauteil-Nummer bevorzugt um eine Identifikationskennung für den Eigentümer bzw. Betreiber des Fahrzeuges sowie eine Identifikationskennung für die Bauart des vorliegenden Radsatzes. Dies ermöglicht es in bestimmten Anwendungen auf eine Online-Verbindung zu einer Datenbank, in der diese Informationen ebenfalls abgespeichert sein könnten, zumindest während des Erfassens der Radsatz-Kennungen zu verzichten. Somit sind auch autarke Anwendungen (ohne Energie- bzw. Dateninfrastruktur) im Gleisbereich ausserhalb von Werkstätten möglich.An advantageous embodiment of the inventive concept provides that the transponder data for unambiguous identification in a freely writable memory area of the wheelset contains. In addition to a clearly assignable one Component number preferably around an identification code for the owner or Operator of the vehicle and an identification code for the type of the present Wheelset. This enables an online connection in certain applications to a database in which this information is also stored could be to do without at least while capturing the wheel set identifiers. Thus, self-sufficient applications (without energy or data infrastructure) are also in the Track area possible outside of workshops.
Der Erfindungsgedanke wird anhand eines in Figur 1 (Querschnitt durch Fahrzeugachse
im Bereich der auf der Achse befestigten Datenübertragungsvorrichtung) dargestellten
Ausführungsbeispiels beschrieben.
Die Vorrichtung besteht im wesentlichen aus einem an sich bekannten, handelsüblichen
passiven Transponder (1). Dieser wird mittels eines beidseitig wirksamen Klebebandes
auf ein versteifend wirkendes Zwischenelement (5) aufgebracht. Dieses ist bezüglich
seiner Grundfläche den Abmessungen des Transponders im wesentlichen angepasst
und besteht z.B. aus dem relativ biegesteifen Werkstoff Polyamid. Transponder mit
Zwischenelement sowie der als Befestigungselement (2) dienende handelsübliche Kabelbinder,
dessen Breite 8 mm keinesfalls unterschreiten sollte, werden in ihrer relativen
Sollposition zueinander durch Verkleben fixiert und in einen Schrumpfschlauch (3)
aus Elastomer oder Polyolefin Compound (PO) eingeführt. Der Schrumpfschlauch ist
mit einem Längenmass, das den Umfang der Fahrzeugachse (4) an der vorgesehenen
Einbaustelle um circa 10% unterschreitet, derart bemessen, dass die Verschlussvorrichtung
(7) sowie die Verzurrstrecke des Kabelbinders (2) frei bleiben bzw. nicht abgedeckt
werden. In der Minimalausführung muss zumindest der Kontaktbereich des
Transponders (1) (bzw. des versteifenden Zwischenelementes (5)) mit dem Befestigungselement
(2) abgedeckt werden. Sodann werden Befestigungselement, Zwischenelement
und Transponder mittels Heissluft zu einem untrennbaren Komposit verbunden.
Alternativ zum Einsatz eines Schrumpfschlauches bietet sich auch ein Vergiessen
mit Epoxidharz und / oder Polyurethanharz oder ähnlichen Kunststoffen an. Dies kann
beispielsweise durch Eintauchen in ein Kunststoff-Heissbad erfolgen.
Natürlich sind an Stelle eines Kabelbinders auch sonstige Spannringe, bevorzugt aus
rostfreiem Edelstahl einsetzbar. Hierbei ist jedoch darauf zu achten, dass die metallischen
Kanten der Spannringe nicht die schützende und stabilisierend KunststoffUmmantelung
im Bereich des Transponders durch Scheuern etc.... schädigen.
Dieses durch Schrumpfen bzw. Vergiessen erhaltene Komposit wird schliesslich in bekannter
Weise auf der Achse des zu kennzeichnenden Radsatzes befestigt. Die Positionierung
des Transponders ist sowohl in axialer als auch in radialer Richtung auf der
Fahrzeugachse frei wählbar und frei von masslichen Randbedingungen.
Zum Auslesen der Identifikationsmerkmale an erfindungsgemäss ausgestatteten
Radsätzen führt das Bedienpersonal bei Fahrzeugstillstand ein Handlesegerät bis auf
einen Abstand von circa 2 bis 4 cm an die Datenübertragungsvorrichtung heran. The inventive concept is described with reference to an exemplary embodiment shown in FIG. 1 (cross section through the vehicle axle in the area of the data transmission device attached to the axle).
The device essentially consists of a commercially available passive transponder (1) which is known per se. This is applied to a stiffening intermediate element (5) by means of an adhesive tape effective on both sides. With regard to its base area, this is essentially adapted to the dimensions of the transponder and consists, for example, of the relatively rigid material polyamide. The transponder with intermediate element and the standard cable tie serving as a fastening element (2), the width of which should not be less than 8 mm, are fixed in their relative target position by gluing and inserted into a shrink tube (3) made of elastomer or polyolefin compound (PO). The shrink tube is dimensioned with a length dimension that is less than the circumference of the vehicle axle (4) at the intended installation point by such a way that the locking device (7) and the lashing distance of the cable tie (2) remain free or are not covered. In the minimum version, at least the contact area of the transponder (1) (or the stiffening intermediate element (5)) must be covered with the fastening element (2). The fastening element, intermediate element and transponder are then connected to an inseparable composite by means of hot air. As an alternative to using a shrink tube, it is also possible to cast with epoxy resin and / or polyurethane resin or similar plastics. This can be done, for example, by immersing it in a plastic hot bath.
Of course, other clamping rings, preferably made of stainless steel, can be used instead of a cable tie. However, it must be ensured that the metallic edges of the clamping rings do not damage the protective and stabilizing plastic sheathing in the area of the transponder by rubbing etc.
This composite obtained by shrinking or potting is finally fastened in a known manner on the axle of the wheel set to be identified. The positioning of the transponder can be freely selected in the axial as well as in the radial direction on the vehicle axis and is free from dimensional constraints.
In order to read out the identification features on wheel sets equipped according to the invention, when the vehicle is stationary, the operating personnel leads a hand-held reader up to a distance of approximately 2 to 4 cm to the data transmission device.
