Abstract

The two photoelectric sensors are mounted in two housings on a spacing bar on the roof of a rail vehicle, and they are mounted at a fixed distance from each other form a certain angle, pref. 90 deg. and an electronic data processing unit receives signals from the two photoelectric sensing systems as in 2440085. The device can be used for continuous measurement of the thickness of the contact wire (9) by measuring the width of the shadow of the wire thrown on the photoelectric receivers, and hence the thickness of the wire in two directions 90 deg. apart is determined. The photoelectric sensors consist of arrays of photodiodes and lenses to focus images of the wire onto the arrays.

Patentanmeldung P 24 40 085.9.Patent application P 24 40 085.9.

Die Verwendungsmöglichkeit der durch die Hauptpatentanmeldung vorgeschlagenen Meßmethode soll durch Erfassung einer weiteren wesentlichen Meßgröße erweitert urid verbessert werden.The possibility of using the proposed by the main patent application The measuring method is to be expanded by the acquisition of a further essential measured variable be improved.

Die Erfindung besteht für eine Einrichtung der eingangs genannten Art nun darin, daß die Einrichtung zur vorzugsweise laufenden Bestimmung der Dicke des Fahrdrahtes einsetzbar ist. Die Messung dieses Parameters ist wichtig für die Wartung und Begutachtung des Zustandes des Fahrdrahts. Dieser ist ständigem Verschleiß unterworfen und soll nach den Bahnbestimmungen bei 20 X Abnutzung an der schlechtesten Stelle ausgetauschttwerden.The invention consists of a device of the type mentioned at the beginning Kind now is that the device for preferably ongoing determination of the thickness of the contact wire can be used. The measurement of this parameter is important for the Maintenance and assessment of the condition of the contact wire. This is constant wear and tear subject and should according to the railway regulations at 20 X wear at the worst Position to be exchanged.

In Ausbildung der Erfindung ist für die Dickenbestimmung die durch den Durchmesser des Fahrdrahtes hervorgerufene mittlere Abschattungszone, begrenzt durch die sauberen Hell-Dunkel-Übergänge im Sensor, in Verbindung mit der elektronischen Meßwertverarbeitungseinheit ausnutzbar.In an embodiment of the invention, for determining the thickness, the through the diameter of the contact wire caused middle shading zone, limited due to the clean light-dark transitions in the sensor, in connection with the electronic one Measured value processing unit can be used.

Anhand eines schematischen Ausführungsbeispiels wird im Nachstehenden die Erfindung näher erläutert.With the aid of a schematic exemplary embodiment, in the following the invention explained in more detail.

In der Zeichnungsfigur ist die auf dem Dach eines Meßwagens montierte Einrichtung angedeutet. Mit sind die jeweils in Gehäusen befindlichen fotoelektrischen Sensoren 1 bezeichnet, die durch ein Distanzstück 2, in definiertem Abstand gehalten, auf dem Dach 5 des Meßwagens befestigt sind. Der zu messende Fahrdraht ist mit 9 angegeben. Er kann sich durch Höhen- und Seitenschwankungen, hervorgerufen durch die Aufhängung oder durch Eigenbewegungen, irgendwo in dem schraffiert angedeuteten Viereck, befinden. Innerhalb dieses Vierecks muß er von den Sensoren voll erfaßbar sein, d.h. der Öffnungswinkel der Sensoren 1 muß richtig gewähltwsdyn.-Als fotoelektrische Sensoren finden vorteilhaft Diodenzeilen mit vorgesetzter Optik Verwendung. Blenden sorgen für die. bötige Tiefenschärfe. Der Durchmesser des Fahrdrahts 9 sorqt für eine mittlere Abschattungszone 10 mit zwei äußeren Hell-Dunkel-thergängen 11,12.In the drawing figure is mounted on the roof of a measuring vehicle Facility indicated. With are the photoelectric in each case Sensors 1 denotes, which are held at a defined distance by a spacer 2, are attached to the roof 5 of the measuring vehicle. The one to be measured Contact wire is indicated with 9. It can be caused by fluctuations in height and side by the suspension or by own movements, somewhere in the hatched line Square. Within this square it must be fully detectable by the sensors be, i.e. the opening angle of the sensors 1 must be selected correctly Sensors are advantageously used with rows of diodes with optics in front. Bezels take care of the. necessary depth of field. The diameter of the contact wire 9 sorqt for a middle shading zone 10 with two outer light-dark corridors 11, 12.

Aus der Anzahl bzw. dem Verhältnis der abgeschatteten oder auch belichteten Dioden zur Gesamtzahl der Dioden der Zeile ist die Dicke des Fahrdrahtes 9 errechenbar. Dies erfolgt zweckmäßig in einem Rechner, z.B. in der auch für die Höhen- und Seitenlagemessung vorgesehenen Meßwertverarbeitungseinheit, die hier nicht besonders dargestellt ist. Durch die Erfindung ist es möglich, den Fahrdraht laufend, d.h. auch während der Fahrt, an zwei Stellen des Umfangs recht genau auf seine Abnutzung zu untersuchen.From the number or the ratio of the shaded or also exposed Diodes The thickness of the contact wire 9 can be calculated in relation to the total number of diodes in the row. This is expediently done in a computer, e.g. also for the height and lateral position measurement provided measured value processing unit, which is not particularly shown here. The invention makes it possible to keep the contact wire running, i.e. also during the Drive, to examine very carefully at two points on the circumference for its wear.
