A device for supplying power to and controlling several electrically operated model vehicles (7) on one circuit (8) using a stationary control circuit (5) which transmits the control pulses to the circuit (1) in the form of positive and negative pulses and, at the same time, provides the electrical energy to be supplied to the model vehicles (7) in those pulses, characterized in that the pulses separated from one another by pulse intervals are delivered to the circuit (1) via one or more capacitors (6) to permit the simultaneous operation of conventional d.c.-operated model vehicles (4) ; in that, in those periods when no information is being transmitted, power is supplied to the model vehicles (7) in the form of the alternately positive and negative pulses transmitted at the transmission frequency ; and in that the pulse frequency selected is so high that the inductance of the conventional d.c.-operated electric motors of the model vehicles (4) represents such a high resistance to the pulse sequences transmitted that the model vehicles (4) are not affected by those pulse sequences of which the energy consumption is minimal.

Description

Die Erfindung betrifft ein Verfahren zur gleichzeitigen selektiven übertragung von digitaler Information und elektrischer Leistung auf mehrere elektrische Modellfahrzeuge (z.B. Modelleisenbahnen oder Autos auf Modellrennbahnen), bei dem mehrere Fahrzeuge zusammen mit konventionellen gleichspannungs- oder netzfrequent-gesteuerten Fahrzeugen betrieben und gesteuert werden. Diese Aufgabenstellung liegt in der Spielwarentechnik vor. Bei dem Betrieb einer Modelleisenbahn ist beispielsweise dasrgleichzeitige voneinander unabhängige Fahren mehrerer Züge erwünscht. Bisherige Lösungen erreichen dieses Ziel nur mit Einschränkungen. In einer konventionellen Modellbahnanlage wird das Fahrverhalten der Modellzüge über eine Niedervoltspannung, die mittels eines Leiters (Schienen und/oder Oberleitung) den Antriebsmotoren zugeführt wird, geregelt. Sollen mehrere Züge in der Modellanlage unabhängig voneinander fahren, müssen diese sich auf verschiedenen, voneinander isolierten Stromkreisen befinden.The invention relates to a method for the simultaneous selective transmission of digital information and electrical power to several electric model vehicles (e.g. model trains or cars on model racetracks), in which several vehicles are operated and controlled together with conventional DC voltage or network frequency controlled vehicles. This task is in toy technology. When operating a model railroad, for example, simultaneous independent driving of several trains is desirable. Previous solutions only achieve this goal with restrictions. In a conventional model railroad system, the driving behavior of the model trains is regulated via a low voltage, which is fed to the drive motors by means of a conductor (rails and / or overhead line). If several trains in the model system are to run independently of one another, they must be on different, isolated circuits.

Ein häufig verwendetes Prinzip zum Steuern eines zusätzlichen Zuges auf ein und demselben Stromkreis bedient sich einer dem konventionellen Gleichstromkreis überlagerten Wechselspannung. Diese liefert die vom zweiten Zug benötigte Energie und steuert durch Variieren der Amplitude und Phasenlage gleich- ) zeitig die Geschwindigkeit des zweiten Zuges. Bei der Verwendung von Netzfrequenz (50 Hz bzw. 60 Hz) treten jedoch unerwünschte Leistungsminderung und zusätzliche mechanische und thermische Belastungen der Fahrmotoren auf. Nachteilig ist außerdem die Beschränkung auf nur zwei Züge auf einem Stromkreis.A frequently used principle for controlling an additional train on one and the same circuit uses an AC voltage superimposed on the conventional DC circuit. This delivers the energy required by the second train and simultaneously controls the speed of the second train by varying the amplitude and phase position. When using mains frequency (50 Hz or 60 Hz), however, undesirable performance degradation and additional mechanical and thermal loads on the traction motors occur. Another disadvantage is the restriction to only two trains on one circuit.

Einige moderne Vorschläge benutzen die Trennung zwischen Energiezufuhr und Steuerung der Fahrmotoren. Die Energie wird zumeist mit konstanter Wechselspannung über den Stromkreis zugeführt. Jedes Modell mit einem Fahrmotor enthält eine elektrische Empfänger- und Steuerschaltung, die von einem Bedienteil selektiv angesprochen wird und die Fahrenergie für den Fahrmotor aus der anliegenden Wechselspannung in geeigneter Weise dosiert und durch Gleichrichterschaltung in Gleichstrom umwandelt, der für Gleichstrommodellbahnmotoren geeignet ist.Some modern proposals use the separation between energy supply and control of the drive motors. The energy is mostly supplied with constant AC voltage via the circuit. Each model with a traction motor contains an electrical receiver and control circuit, which is addressed selectively by a control panel and doses the driving energy for the traction motor from the applied AC voltage in a suitable manner and converts it into direct current by means of a rectifier circuit, which is suitable for DC model railroad motors.

Neben diesem ferngesteuerten Betrieb ist zum Teil gleichzeitig ein konventioneller Betrieb mit gleich- oder netzfrequentem Wechselstrom möglich, bei dem das Fahrzeug durch die Spannung der zugeführten Energie gesteuert wird. In diesem Fall sind passive Siebglieder zum selektiven Empfang nötig, die unerwünschten Platzbedarf und Kosten sowie eine Justage erfordern. Andere Systeme, die diesen Nachteil nicht aufweisen, lassen wiederum den konventionellen Betrieb nicht zu. 'Gelegentlich werden auch Schaltungen benutzt, die eine Pulslängenmodulation aufweisen und passive Zeitglieder erfordern, die sich schlecht in integrierte Schaltungen umsetzen lassen.In addition to this remote-controlled operation, conventional operation with AC or DC frequency is also possible, in which the vehicle is controlled by the voltage of the energy supplied. In this case, passive screening elements are required for selective reception, which require undesired space and costs as well as adjustment. Other systems that do not have this disadvantage in turn do not allow conventional operation. 'Circuits are sometimes used that have a pulse length modulation and require passive timers that are difficult to convert into integrated circuits.

Erfindungsgemäß werden die Nachteile der bekannten Verfahren dadurch gelöst, daß

  • ein besonderes Verfahren zur gleichzeitigen Übertragung von Energie und digitaler Information zum Betrieb der Fahrzeuge angewendet wird
  • und daß über einen oder mehrere Trennkondepsatoren in zeitlicher Folge Impulse mit jeweil's einer kurzen Pause dazwischen auf den Stromkreis gelegt werden und daß die mit den Impulsen gelieferte Energie zum Betrieb der ferngesteuerten Fahrzeuge benutzt wird
  • und daß der Gleichstrommittelwert der Impulsfolge verschwindet und die Impulsfrequenz so hoch ist, daß konventionelle Gleichstrommotoren infolge ihrer Induktivität einen hohen.Widerstand für die Impulsfolge darstellen und weder konventionelle Gleichstrommotoren durch die Impulsfolge noch das Senden der Impulsfolge durch konventionelle Gleichstrommotoren gestört werden
  • und daß die Impulse verschiedenen Vorzeichens von den Empfängern.als entgegengesetzte logische Werte aufgefaßt werden
  • und daß die Trennung zweier Impulse mit Hilfe der zwischen Ihnen vorhandenen Impulspause erfolgt
  • und daß ein Fahrzeug, dessen zwei Anschlüsse durch Umdrehen auf der Schiene vertauscht werden, was ein Invertieren der Impulsfolge bezüglich des Empfängers bewirkt, trotzdem eine gültige Information erhält
  • und daß.- wenn keine Information übertragen werden soll - eine Folge von Null- und Eins-Impulsen zur Speisung der Fahrzeuge gesendet wird.
According to the invention, the disadvantages of the known methods are solved in that
  • a special procedure for the simultaneous transmission of energy and digital information is used to operate the vehicles
  • and that one or more isolating capacitors are used to place pulses with a short pause in between on the circuit, and that the energy supplied with the pulses is used to operate the remote-controlled vehicles
  • and that the DC mean value of the pulse train disappears and the pulse frequency is so high that conventional DC motors, due to their inductance, represent a high resistance to the pulse train and neither conventional DC motors are disturbed by the pulse train nor the transmission of the pulse train by conventional DC motors
  • and that the impulses of different signs are interpreted by the receivers as opposite logical values
  • and that the separation of two impulses takes place with the aid of the impulse pause between them
  • and that a vehicle whose two connections are reversed by reversing on the rail, which causes the pulse train to be inverted with respect to the receiver, nevertheless receives valid information
  • and that - if no information is to be transmitted - a sequence of zero and one pulses is sent to feed the vehicles.

Weitere Einzelheiten ergeben sich aus einem Ausführungsbeispiel nach Figur 1.Further details result from an exemplary embodiment according to FIG. 1.

An ein stromleitendes Schienenpaar 1 wird eine konventionelle, einstellbare, umpolbare Gleichstromquelle 2 in Reihe mit einer Drossel 3 angeschlossen. Die Drossel 3 bildet für Gleichstrom einen kleinen, für. auf der Schiene überlagerten Wechselstrom jedoch einen großen Widerstand. Hierdurch wird ein Abfließen von Wechselströmen über die Gleichstromquelle vermieden. Diese Anordnung reicht bereits aus zum Betrieb eines konventionell gleichstrombetriebenen Zuges 4.A conventional, adjustable, reversible polarity direct current source 2 is connected in series with a choke 3 to a current-conducting pair of rails 1. The inductor 3 forms a small one for direct current. over the rail however, AC stored a large resistance. As a result, an outflow of alternating currents via the direct current source is avoided. This arrangement is already sufficient to operate a conventionally DC train 4.

Zur Erzeugung einer Impulsfolge zur Steuerung und gleichzeitigen Energieversorgung eines oder mehrerer zusätzlicher ferngesteuerten Züge ist eine Impulsquelle 5 in Reihe mit einem Trennkondensator 6 parallel auf das Schienenpaar 1 geschaltet. Der Trennkondensator 6 verhindert, daß die Impulsquelle 5 von Gleichstrom oder netzfrequentem Wechselstrom durchflossen wird. Die Impulsfrequenz liegt in diesem Ausführungsbeispiel über der menschlichen Hörgrenze. Gegenüber dieser Frequenz bilden die Fahrmotoren einen so großen Widerstand, daß sie nur von einem vernachlässigbar geringen Wechselstrom durchflossen werden, der weder eine zusätzliche Erwärmung noch eine mechanische Beanspruchung bewirkt.In order to generate a pulse train for the control and simultaneous supply of energy to one or more additional remote-controlled trains, a pulse source 5 is connected in series with a separating capacitor 6 in parallel on the pair of rails 1. The isolating capacitor 6 prevents the pulse source 5 from being flowed through by direct current or mains frequency alternating current. In this exemplary embodiment, the pulse frequency is above the human hearing limit. The traction motors form such a large resistance to this frequency that only a negligible alternating current flows through them, which causes neither additional heating nor mechanical stress.

Figur 2 zeigt den prinzipiellen Aufbau der Impulsquelle 5. Die Information über den gewünschten Fahrzustand stellt der Bediener über Stellknöpfe ein, von denen je einer einem Zug zugeordnet ist. Die Einstellung wird von einer logischen Schaltung 9 in ein Datenwort umgewandelt, das in einer Folge von Nullen und Einsen eine Information trägt, welchem der Züge diese Information zugeordnet ist und ob dieser Zug vorwärts oder rückwärts fahren soll. Der Parallel-Seriell-Wandler 10 wandelt das Datenwort in eine serielle Impulsfolge um, indem er über die vier Schalter 12, 13, 14 und 15 das Schienenpaar 1 über den Kondensator 6 wechselseitig an die Spannungsquelle 11 legt, so daß eine Folge von positiven und negativen Impulsen an dem Schienenpaar entsteht. Zwischen zwei Impulsen wird durch das Schließen der Schalter 13 und 14 für kurze Zeit eine Nullspannung erzeugt.FIG. 2 shows the basic structure of the pulse source 5. The operator sets the information about the desired driving state using control buttons, one of which is assigned to a train. The setting is converted by a logic circuit 9 into a data word which, in a sequence of zeros and ones, carries information as to which of the trains this information is associated with and whether this train should travel forwards or backwards. The parallel-to-serial converter 10 converts the data word into a serial pulse sequence by mutually connecting the pair of rails 1 to the voltage source 11 via the capacitor 6 via the four switches 12, 13, 14 and 15, so that a sequence of positive and negative impulses arise on the pair of rails. A zero voltage is briefly generated between two pulses by closing switches 13 and 14.

Figur 3 zeigt eine typische Folge von Impulsen zur Übertragung der Information an Fahrzeuge.FIG. 3 shows a typical sequence of pulses for transmitting the information to vehicles.

Das Impulsdiagramm besteht aus sechzehn Impulsen. Diese enthalten Information darüber, welche Empfängerschaltung gemeint ist, die Adresse, und ob vorwärts oder rückwärts gefahren werden soll. Empfängt ein Fahrzeug eine gültige, d.h. an deren Empfänger adressierte Information, wird der Fahrstrom für eine feste Zeit auf den Motor geschaltet. Ein gleichmäßiges Fahren wird durch periodisches Ansprechen des Fahrzeugs bewirkt. Die Frequenz bestimmt die Fahrgeschwindigkeit.The pulse diagram consists of sixteen pulses. These contain information about which receiver circuit is meant, the address, and whether to drive forward or backward. If a vehicle receives a valid, i.e. information addressed to its receiver, the travel current is switched to the motor for a fixed time. Smooth driving is achieved by periodically responding to the vehicle. The frequency determines the driving speed.

In diesem Ausführungsbeispiel ist die gesendete Information in folgender Weise aufgebaut: Das Impulsdiagramm beginnt mit einer Folge aus acht Impulsen, die stets in der wahren oder invertierten Form gesendet werden. Die wahre Folge wird in allen Empfängern als Information "vorwärts", die invertierte Folge als "Rückwärts" dekodiert und vorgemerkt.' Gleichzeitig ist das Ende dieser Folge, die im folgenden "Sync-Zeichen" genannt wird, das Zeichen, daß die folgenden 8 Impulse als Adresse.gelten. Diese wird mit einer der Empfängerschaltung eingeprägten Impulsfolge verglichen. Bei Obereinstimmung wird die bei Erscheinen des Sync-Zeichens vorgemerkte Fahrtrichtung gültig und der Fahrstrom für. eine feste Zeit durchgeschaltet.In this exemplary embodiment, the transmitted information is structured as follows: The pulse diagram begins with a sequence of eight pulses, which are always sent in the true or inverted form. The true sequence is decoded and noted as information "forward" in all receivers, the inverted sequence as "backward". ' At the same time, the end of this sequence, which is referred to below as the "sync character", is the sign that the following 8 pulses are to be considered as addresses. This is compared with a pulse train impressed on the receiver circuit. If there is agreement, the direction of travel noted when the sync symbol appears and the current for. switched through a fixed time.

Die gesendete Information wird von dem Fahrzeug über die Schienen abgenommen. Durch die Möglichkeit, dieses in zwei verschiedenen Fahrtrichtungen auf die Schiene zu setzen, wird die Zuordnung zwischen den Empfängeranschlüssen und den Schienen unbestimmt. Hierdurch wird ein Impulstelegramm entweder in seiner wahren oder in seiner invertierten Form aufgenommen. Damit ein Fahrzeug sicher angesprochen wird, sendet die Impulsquelle 5 die Adresse nacheinander in wahrer und invertierter Form jeweils geführt durch ein Sync-Zeichen.The information sent is taken from the vehicle via the rails. The possibility of placing this on the rail in two different directions of travel means that the assignment between the receiver connections and the rails is undetermined. As a result, a pulse telegram is recorded either in its true or in its inverted form. To ensure that a vehicle is addressed safely, the pulse source 5 sends the address one after the other in true and inverted form, each guided by a sync symbol.

Der Benutzer der Anlage kann wählen, ob er die Fahrtrichtung in Bezug auf das Fahrzeug bestimmen möchte. Dann wird zunächst das zur Fahrtrichtung gehörende Sync-Zeichen mit der wahren Adresse und anschließend beides invertiert gesendet. Oder er kann die Fahrtrichtung schienenbezogen wählen. Dann wird ein und dasselbe Sync-Zeichen mit der wahren und der invertierten Adresse nacheinander gesendet. Neben dem hier beschriebenen Ausführungsbeispiel ist auch die Lösung möglich, daß das Fahrzeug die wahre und die invertierte Adresse gleichzeitig erkennen kann. Dabei ergibt sich die Wahl der..Fahrtrich- tungszuordnung nicht.The user of the system can choose whether he wants to determine the direction of travel in relation to the vehicle. Then the sync symbol belonging to the direction of travel is sent with the true address and then both are inverted. Or he can choose the direction of travel based on the rail. Then one and the same sync character with the true and the inverted address is sent in succession. In addition to the exemplary embodiment described here, the solution is also possible that the vehicle can recognize the true and the inverted address at the same time. The choice of direction of travel does not result.

Figur 4 zeigt die Erkennung von.gesendeten positiven und negativen Impulsen aus dem Impulsdiagramm.FIG. 4 shows the detection of transmitted positive and negative pulses from the pulse diagram.

Mit Hilfe zweier Schwelloperationen gemäß der in Figur 4 dargestellten Schwellen wird bei Oberschreiten der Schwelle 15 das Signal S15 gleich 1 und bei überschreiten der Schwelle 16 das Signal S16 gleich 1. Wird dem Impulsdiagramm eine Gleichspannung zum Betrieb eines konventionellen Modellfahrzeugs überlagert, werden die. Schwellen mitgeführt, so daß die Schwelle.15 immer oberhalb und die Schwelle 16 immer unterhalb des Gleichspannungsmittelwertes liegt. - With the help of two threshold operations according to the thresholds shown in FIG. 4, the signal S 15 becomes 1 when the threshold 15 is exceeded and the signal S 16 becomes 1 when the threshold 16 is exceeded. If a DC voltage for operating a conventional model vehicle is superimposed on the pulse diagram, . Thresholds carried so that the threshold 15 is always above and the threshold 16 is always below the DC voltage mean. -

Figur 5 zeigt eine Schaltung zur Umwandlung der aus positiven und negativen Impulsen entstandenen Schwellensignale S15 und S16 in eine logische Folge.FIG. 5 shows a circuit for converting the threshold signals S 15 and S 16 resulting from positive and negative pulses into a logical sequence.

An dem logischen Gatter 17 entsteht genau dann eine logische 1, wenn S15 = 0 und S16 = 1 ist. Ein übergang von der logischen 0 zur 1 entsteht am Ausgang am Ende eines positiven oder negativen Impulses auf der Schiene. Der Ausgang des Gatters 17 ist mit dem dynamischen Takteingang des bistabilen Speichers 18 verbunden, der auf steigende Flanken reagiert. Der vorbereitende Dateneingang des Speichers ist mit dem Signal S15 verbunden. Während eines positiven Impulses ist S15 = 1. An dem Speicher 18 wird die logische 1 vorbereitet. Am Ende des positiven Impulses entsteht die positive Flanke am Takteingang des Speichers, so daß die 1 am Ausgang des Speichers erscheint.A logical 1 arises at the logic gate 17 if and only if S 15 = 0 and S 16 = 1. A transition from logic 0 to 1 occurs at the output at the end of a positive or negative pulse on the rail. The output of the gate 17 is connected to the dynamic clock input of the bistable memory 18, which responds to rising edges. The preparatory data input of the memory is connected to the signal S 15 . S15 = 1 during a positive pulse. Logical 1 is prepared at memory 18. At the end of the positive pulse, the positive edge is created at the clock input of the memory, so that 1 appears at the output of the memory.

Während eines negativen Impulses ist S15 = 0, so daß die logische Null vorbereitend an den Speicher gelegt wird. Am Ende des negativen Impulses erzeugt der übergang von Null auf Eins des Schwellensignals S16 die Taktflanke zum Abspeichern der Null im Speicher 18.During a negative pulse, S 15 = 0, so that the logical zero is preparatively applied to the memory. At the end of the negative pulse, the transition from zero to one of the threshold signal S 16 generates the clock edge for storing the zero in the memory 18.

Dem Speicher 18 ist ein seriell-parallel wapdelndes Schieberegister 19 nachgeschaltet, das mit dem gleichen Takt beaufschlagt wird wie der Speicher 18. Am Ausgang des Schieberegisters steht die gesendete Impulsfolge als paralleles Datenwort zur Verfügung.The memory 18 is followed by a serial-parallel, shifting shift register 19, to which the same clock is applied as the memory 18. At the output of the shift register, the pulse train sent is available as a parallel data word.

In einer Schaltungsvariante ist der Speicher 18 mit dem ersten Speicherelement.des Schieberegisters identisch.In one circuit variant, the memory 18 is identical to the first memory element of the shift register.
