Abstract

The automatic guidance control system for trackless vehicles uses induced signals based upon a conductor inset in the ground surface. A facility is included for a change in vehicle direction at a junction. At the junction the guide conductor (1) divides into two separate paths (2, 3). A group of parallel conductors (2a, 2b, 2c, 2d and 3a, 3b, 3c, 3d) are coupled over connected contacts (4, 5), such that one contact is open when the other is closed. When one contact is open (5) and the other closed (4) the field on one side is more pronounced than on the other. The onboard detectors provide a signal difference to control the steering gear.

Es ist bekannt, ein Fahrzeug, das nicht schienengebunden ist, längs einer Strecke mit Hilfe eines Leitkabels zu führen. In das Leitkabel wird ein Wechselstrom eingespeist, dessen magnetisches Wechselfeld eine Spannung in am Fahrzeug befindliche Antennen speist. Insbesondere dient als Antenne eine Ferritantennenanordnung, bestehend aus zei senkrecht zueinanderstehenden induktiven Koppelspulen mit Ferritkernen, wobei die eine Spule waagerecht zum Fahrzeugboden, die andere senkrecht zum Fahrzeugboden am Fahrzeug angebracht ist. Eine solche Einrichtung und eine Auswertung der in die beiden Spulen induzierten Spannungen mittels einer Brückenschaltung ist in der DU-PS 12 75 291 dargestellt.It is known to have a vehicle that is not rail-bound longitudinally to guide a route with the help of a guide cable. An alternating current is fed into the guide wire fed, whose alternating magnetic field generates a voltage in the vehicle Antennas feeds. In particular, a ferrite antenna arrangement, consisting of, serves as the antenna from two perpendicular inductive coupling coils with ferrite cores, with one coil horizontal to the vehicle floor, the other perpendicular is attached to the vehicle floor on the vehicle. Such a facility and an evaluation of the voltages induced in the two coils by means of a bridge circuit shown in the DU-PS 12 75 291.

Es ist ferner bekannt, bei Abzweigungen durch Umschaltung des eingespeisten Stroms auf die gewünschte Abzweigung die Fahrtrichtung zu steuern, vergl. die DT-OS 25 ovo 792, Fig. 2 mit Beschreibung. Damit wird aber der gesamte Abschnitt hinter dem Abzweig, der nicht befahren werden soll, stromlos und damit für das induktive Lenken der sich dort befindlichen Fahrzeuge und für den Datenaustausch mit ihnen unbrauchbar.It is also known to switch the fed in at branches Current to control the direction of travel on the desired junction, see the DT-OS 25 ovo 792, Fig. 2 with description. But this leaves the entire section behind the branch that is not to be driven on, de-energized and thus for the inductive Steering the vehicles located there and exchanging data with them unusable.

Es sind ferner Weichensteuerungen bekannt, die vor den Weichen diese charakterisierende Codiermittel enthalten, die vom Fahrzeug gelesen, dort ausgewertet und dann zur Steuerung des Fahrweges benutzt werden (DU-PS 14 81 482, DT-AS 19.04 377, D?-AS 21 37 864, DT-OS 22 57 081, D?-hS 24 30 378). Diese Weichensteuerung ist aber sehr aufwendig. Ähnlich aufwendig ist eine bekannte Einrichtung, bei der das Fahrzeug signalgebende Einrichtungen besitzt, deren Signale vor den Weichen aufgenommen werden und dann zur Weichensteuerung dienen (DT-OS 18 06 756).There are also switch controls known that this before the switches contain characterizing coding means that are read by the vehicle and evaluated there and then used to control the route (DU-PS 14 81 482, DT-AS 19.04 377, D? -AS 21 37 864, DT-OS 22 57 081, D? -HS 24 30 378). This point control but is very complex. A known device in which the vehicle has signaling devices whose signals are in front of the points and then used to control points (DT-OS 18 06 756).

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Steuern der Fahrtrichtung anzugeben ohne zusätzliche Lese- und Auswertmittel auf dem Fahrzeug, die von den obengenannten Nachteilen frei ist.The invention is based on the object of a device for controlling indicate the direction of travel without additional reading and evaluation equipment on the vehicle, which is free from the above-mentioned disadvantages.

Ein Ausführungsbeispiel für die Einrichtung gemäß der Erfindung wird nachstehend an Hand der Zeichnung näher erläutert.An embodiment for the device according to the invention is explained in more detail below with reference to the drawing.

In der Figur ist mit 1 ein Leitkabel bezeichnet, das sich am Entscheidungspunkt W verzweigt, und zwar in das Leitkabel 2 (linker Weichenstrang) und in das Leitkabel 3 (rechter Weichenstrang). In kurzer Entfernung nach dem Entscheidungspunkt sind parallel zum Leitkabel 2 mit bestimmter Länge Leiter 2a, 2b, 2c und 2d verlegt, die bestimmte Abstände vom Leitkabel aufweisen. Diese sind in Abzweigrichtung miteinander und dem Leitkabel verbunden. In Richtung zum Verzweigungspunkt sind die parallelen Leiter ebenfalls miteinander verbunden und führen auf einen Schalter 4, der mit dem Leitkabel 2 unmittelbar nach dem Entscheidungspunkt verbunden ist.In the figure, 1 denotes a guide cable, which is located at the decision point W branches into the guide cable 2 (left turnout line) and the guide cable 3 (right turnout line). Are a short distance after the decision point laid parallel to guide cable 2 with a certain length of conductors 2a, 2b, 2c and 2d, which have certain distances from the guide wire. These are in the branching direction with each other and the guide wire connected. Towards the branch point are the parallel ones Head also connected to each other and lead to a switch 4, which with connected to the guide wire 2 immediately after the decision point.

Entsprechend sind parallel zum Leitkabel 3 Leiter 3a, 3b, 3c, 3d verlegt, in Abzweigrichtung mit diesem verbunden und in Richtung zum Entscheidungspunkt über einen Schalter 5 mit dem Leitkabel 3 verbunden. Die Schalter 4 und 5 schließen und öffnen wechselseitig.Correspondingly, 3 conductors 3a, 3b, 3c, 3d are laid parallel to the guide cable, connected to this in the branching direction and towards the decision point connected to the guide cable 3 via a switch 5. Switches 4 and 5 close and open alternately.

Die Wirkung der Einrichtung ist folgende: in der in der Figur dargestellten Schalterstellung (Schalter 4 geschlossen, Schalter 5 geöffnet) wird eine Lenkfeldschwächung durch die seitliche Ausbreitung des magnetischen Feldverlaufes erreicht. Ein auf die Weiche zufahrendes Fahrzeug orientiert sich nach dem nicht verzweigten Strom. Es fährt also längs 3 des Leitkabelsweiter.The effect of the device is as follows: in the one shown in the figure Switch position (switch 4 closed, switch 5 open) is a steering field weakening achieved by the lateral spread of the magnetic field. One on the vehicle approaching the switch is based on the non-branched flow. So it continues along 3 of the guide wire.

Bei entgegengesetzter Schaltstellung der Schalter 4 und 5 fährt ein Fahrzeug dagegen in Richtung des Leitkabels 2.In the opposite switch position, switches 4 and 5 retract Vehicle, however, in the direction of the guide wire 2.

Nach Durchfahren der Weiche wird durch das stationäre magnetische Wechselfeld immer ein Lenksignal breitgesellt,After passing the switch, the stationary magnetic Alternating field always provides a steering signal,
