Description

Die Erfindung betrifft eine durch ein 3-Punkt-Stellsignal ansteuerbare Antriebsvorrichtung zum Antreiben von Stellgliedern gemäß der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a controllable by a 3-point control signal drive device for driving actuators according to the type specified in the preamble of claim 1.

Bei den anzutreibenden Stellgliedern handelt es sich beispielsweise um sogenannte 3-Wege-Ventile, wie sie in Anlagen der Haus- oder Verfahrenstechnik zu Steuerung von Fluidströmen zum Einsatz kommen können. Derartige Stellglieder und ihre Verwendung sind dem Fachmann bekannt und werden daher an dieser Stelle nicht näher erläutert.The actuators to be driven, for example, are so-called 3-way valves, as they can be used in systems of domestic or process engineering for controlling fluid flows. Such actuators and their use are known in the art and are therefore not explained in detail here.

Bekannte durch ein 3-Punkt-Stellsignal ansteuerbare Antriebsvorrichtungen zum Antreiben von Stellgliedern sind nur von einem für sie passend ausgelegten 3-Punkt-Stellsignal ansteuerbar, denn die bekannten Antriebsvorrichtungen sind nur für ein bestimmtes 3-Punkt-Stellsignal einer bestimmten Spannungsart, einer bestimmten Spannungshöhe (und/oder Stromhöhe) und einer bestimmten Frequenz des Signals ausgelegt.Known by a 3-point control signal controllable drive devices for driving actuators can only be controlled by a suitably designed for them 3-point control signal, because the known drive devices are only for a specific 3-point control signal of a certain voltage, a certain voltage level (and / or current level) and a specific frequency of the signal designed.

Da unterschiedliche Spannungsnetze existieren, beispielsweise in anderen Ländern (z.B. Deutschland/Europa AC, 230V, 50 Hz oder USA AC, 120V, 60 Hz), ergeben sich an unterschiedlichen Einsatzorten u.U. unterschiedliche 3-Punkt-Stellsignale. Besteht also die Anforderung, die bekannten Antriebsvorrichtungen durch verschiedene 3-Punkt-Stellsignale anzusteuern, so müssen verschiedene, an das jeweilige 3-Punkt-Stellsignal angepasste Antriebsvorrichtungen verwendet werden.Since different voltage networks exist, for example in other countries (for example Germany / Europe AC, 230V, 50 Hz or USA AC, 120V, 60 Hz), u.U. different 3-point control signals. So there is the requirement to control the known drive devices by various 3-point control signals, so different, adapted to the respective 3-point control signal drive devices must be used.

Die bekannten Antriebsvorrichtungen sind also mit dem Nachteil behaftet, dass sie nur für ein bestimmtes 3-Punkt-Stellsignal ausgelegt sind. Demzufolge müssen für unterschiedliche 3-Punkt-Signale verschiedene Antriebsvorrichtungen eingesetzt werden. Dies ist mit einem hohen wirtschaftlichen Aufwand verbunden.The known drive devices are therefore subject to the disadvantage that they are designed only for a specific 3-point control signal. As a result, different drive devices must be used for different 3-point signals become. This is associated with a high economic outlay.

Das Dokument DE 411 1 039 beschreibt einen Antrieb mit 3-Punkt-Stellsignalen zum Betrieb an Wechsel- oder Gleichspannung mit unterschiedlicher Höhe.The document DE 411 1 039 describes a drive with 3-point control signals for operation on AC or DC voltage with different heights.

Demgemäss ist es die Aufgabe der Erfindung, eine Antriebsvorrichtung zu schaffen, welche die geschilderten Probleme behebt.Accordingly, it is the object of the invention to provide a drive device which overcomes the problems described.

Die Erfindung löst die Aufgabe mit einer Antriebsvorrichtung mit den Merkmalen des Anspruches 1.The invention solves the problem with a drive device having the features of claim 1.

Erfindungsgemäß weist die Antriebsvorrichtung eine Anpassungsschaltung zur Anpassung der Antriebsvorrichtung an unterschiedliche 3-Punkt-Stellsingnale entsprechend vorgebbarer Parameter auf. Dadurch wird eine Antriebsvorrichtung geschaffen, die durch sich hinsichtlich Spannungsart, Spannungs- und/oder Stromhöhe, Frequenz unterscheidenden 3-Punkt-Signale angesteuert werden kann, so dass es nicht mehr notwendig ist, verschiedene Antriebsvorrichtungen bereit zu halten.According to the invention, the drive device has a matching circuit for adapting the drive device to different 3-point actuating inputs according to predefinable parameters. As a result, a drive device is provided which can be controlled by three-point signals which differ in terms of voltage type, voltage and / or current height, frequency, so that it is no longer necessary to keep various drive devices ready.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the dependent claims.

Die Erfindung wird nachfolgend in Verbindung mit der beiliegenden Zeichnung anhand eines Ausführungsbeispiels näher erläutert. Es zeigt:

Weiterhin ist ein mit dem Antrieb 3 über eine Drehachse 4 verbundenes und antreibbares Stellglied 5 mit einem Getriebe 6 und einem Ventil 7 dargestellt. Fig. 1 shows an inventive controllable by a 3-point control signal drive device 1, which has a matching circuit 2 according to the invention and a drive 3. Furthermore, a connected to the drive 3 via a rotation axis 4 and driven actuator 5 with a gear 6 and a valve 7 is shown.

Ggf. für die Funktion von Stellgliedern erforderliche Endschalter oder ähnliche Einrichtungen sind aus Gründen der Übersichtlichkeit nicht dargestellt. Derartige Einrichtungen und die Funktionsweise dieser Einrichtungen sind dem Fachmann bekannt und werden daher in der vorliegenden Offenbarung nicht weiter beschrieben.Possibly. For the function of actuators required limit switches or similar devices are not shown for reasons of clarity. Such devices and the operation of these devices are known in the art and are therefore not further described in the present disclosure.

Die Antriebsvorrichtung 1 ist weiterhin über Anschlüsse, hier einen Eingangklemmenblock 11, mittels elektrischer Verbindungen (nicht dargestellt) mit einer Schaltungsanordnung 8 zur Erzeugung von DC (Gleichspannungs-) 3-Punkt-Stellsignalen oder von AC (Wechselspannungs-) 3-Punkt-Stellsignalen verbunden. Die Schaltungsanordnung 8 weist eine Gleichspannungsquelle (DC, + / -), einen Gleichspannungsumschalter 9, eine Wechselspannungsquelle (AC, L / N) und einen Wechselspannungsumschalter 10 auf.The drive device 1 is further connected via connections, here an input terminal block 11, by means of electrical connections (not shown) to a circuit arrangement 8 for generating DC (DC) 3-point actuating signals or AC (AC voltage) 3-point actuating signals , The circuit arrangement 8 has a DC voltage source (DC, + / -), a DC voltage changeover switch 9, an AC voltage source (AC, L / N) and an AC voltage changeover switch 10.

Die Schaltungsanordnung 8 ist derart ausgestaltet, dass der Eingangsklemmenblock 11 der Antriebsvorrichtung 1 entweder mit einem DC- oder mit einem AC- 3-Punkt-Stellsignal beaufschlagt werden kann, nicht jedoch gleichzeitig mit einem AC und einem DC Signal.The circuit arrangement 8 is designed in such a way that the input terminal block 11 of the drive device 1 can be supplied with either a DC or an AC 3-point actuating signal, but not simultaneously with an AC and a DC signal.

Die dargestellte Schaltungsanordnung 8 dient der Erläuterung der Funktionsweise der vorliegenden Erfindung und ist nicht Bestandteil derselben.The illustrated circuit arrangement 8 serves to explain the operation of the present invention and is not part of the same.

Im Folgenden wird die Funktion der erfindungsgemäßen Antriebsvorrichtung 1 erläutert.The function of the drive device 1 according to the invention is explained below.

Wie bereits ausgeführt, ist die Antriebsvorrichtung 1 derart ausgestaltet, dass sie mir Wechselspannungs- und mit Gleichspannungs-3-Punkt-Stellsignalen angesteuert werden kann.As already stated, the drive device 1 is designed such that it can be driven by AC voltage and with DC 3-point actuating signals.

Unter einem 3-Punkt-Stellsignal wird i.A. ein Signal zur Ansteuerung von Stellgliedern verstanden, die 3 Zustände kennen: Öffnen, Schließen und Stop.Under a 3-point control signal i.A. a signal for controlling actuators, which know 3 states: open, close and stop.

Bei einem Stellglied, das durch einen Motor angesteuert wird entsprechen diese Zustände den Signalen Linkslauf (beispielsweise: zu), Rechtslauf (beispielsweise: auf) und keine Bewegung, d.h. das Stellglied verharrt in der augenblicklichen Stellung (beispielsweise in einer Mittelstellung).For an actuator that is controlled by a motor, these states correspond to the signals counterclockwise (for example: closed), clockwise (for example: on) and no movement, ie the actuator remains in the current position (for example in a middle position).

Zur Ansteuerung der Antriebsvorrichtung 1 mit Gleichspannungs-3-Punkt-Stellsignalen werden die mit (+) L↑ und mit (-) L↓ bezeichneten Einzelklemmen des Klemmenblocks 11 mit einer Gleichspannung beaufschlagt. Die mit N bezeichnete Einzelklemme des Klemmenblocks 11 bleibt in diesem Fall unbelegt und somit ohne Funktion.To control the drive device 1 with DC 3-point control signals designated with (+) L ↑ and with (-) L ↓ individual terminals of the terminal block 11 are subjected to a DC voltage. The designated individual terminal of the terminal block 11 11 remains unoccupied in this case and thus without function.

Zur Anpassung von Gleichspannungs-3-Punkt-Stellsignalen weist die Anpassungsschaltung 2 einen Gleichspannungsbaustein 12 auf, dieser schaltet nur Gleichspannung (unabhängig von deren Polarität) auf einen Motortreiber 13 durch und wandelt die durchgeschaltete Gleichspannung in einen von dem Motortreiber 12 verarbeitbaren Wert entsprechend vorgebbarer Parameter, wie beispielsweise Spannungshöhe, um. Der Motortreiber 13 erkennt die Polarität der an die Einzelklemmen (+) L↑ und (-) L↓ und dann durch den Gleichspannungsbaustein 12 gewandelten Gleichspannung und steuert den Antrieb 3 entsprechend an (Linkslauf, Rechtslauf).For adaptation of DC 3-point actuating signals, the matching circuit 2 has a DC component 12, which only switches DC voltage (regardless of its polarity) to a motor driver 13 and converts the switched DC voltage into a value that can be processed by the motor driver 12 in accordance with predefinable parameters , such as voltage level, um. The motor driver 13 detects the polarity of the direct voltage to the individual terminals (+) L ↑ and (-) L ↓ and then through the DC voltage component 12 and controls the drive 3 accordingly (counterclockwise, clockwise).

Zur Anpassung von Wechselspannungs-3-Punkt-Stellsignalen weist die Anpassungsschaltung 2 zwei Gleichrichter 14, zwei Standard-Optokoppler 15, zwei Richtungsanzeige-Optokoppler 16, einen Konstantstromregler 17, sowie einen Wechselspannungs/Gleichspannungswandlernetzteil 18 auf.For matching AC 3-point actuating signals, the matching circuit 2 has two rectifiers 14, two standard optocouplers 15, two directional display optocouplers 16, a constant current regulator 17, and an AC / DC converter power supply 18.

Zur Ansteuerung der Antriebsvorrichtung 1 mit Wechselspannungs-3-Punkt-Stellsignalen werden entweder die mit (+) L↑ und mit N bezeichneten Einzelklemmen des Klemmenblocks 11 oder die mit (-) L↓ und mit N bezeichneten Einzelklemmen des Klemmenblocks 11 mit einem Wechselspannungssignal beaufschlagt.To control the drive device 1 with AC three-point control signals either the (+) L ↑ and N designated individual terminals of the terminal block 11 or (-) L ↓ and N designated individual terminals of the terminal block 11 are supplied with an AC signal ,

In beiden Fällen wird die zwischen (+) L↑ und N oder (-) L↓ und N angelegte Wechselspannung von dem mit dem entsprechenden Eingang verbundenen Gleichrichter 14 gleichgerichtet. Durch den mit dem jeweiligen Eingang (+) L↑ oder (-) L↓ verbundenen Standard-Optokoppler 15 wird das Netzteil 18 mit Wechselspannung versorgt. Das Netzteil 18 wandelt die angelegte Wechselspannung entsprechend vorgebbarer Parameter in eine von dem Motortreiber 13 verarbeitbare Gleichspannung zur Speisung des Antriebs 3 um.In both cases, the AC voltage applied between (+) L ↑ and N or (-) L ↓ and N is rectified by the rectifier 14 connected to the corresponding input. By the with the respective input (+) L ↑ or (-) L ↓ connected standard optocoupler 15, the power supply 18 with AC voltage supplied. The power supply 18 converts the applied AC voltage according to specifiable parameters in a processable from the motor driver 13 DC voltage to power the drive 3.

Über die mit dem jeweiligen Eingang (+) L↑ oder (-) L↓ verbundenen (in Serie mit dem Gleichrichter 14 und dem Standard-Optokoppler 15) Richtungsanzeige-Optokoppler 16 wird dem Motortreiber 13 die jeweilige Drehrichtung über dessen mit ↑ und ↓ bezeichneten Eingängen signalisiert.Directional display optocoupler 16 (in series with the rectifier 14 and the standard optocoupler 15) connected to the respective input (+) L ↑ or (-) L ↓ the motor driver 13, the respective direction of rotation via its designated by ↑ and ↓ Inputs signaled.

Zum Schutz der mit den Bezugszeichen 14, 15 und 16 bezeichneten Bauelemente gegen Überströme wird der durch diese fließende Strom mittels des Konstantstromreglers 17 auf einen für diese Bauelemente unschädlichen Wert begrenzt.To protect the components denoted by the reference numerals 14, 15 and 16 against overcurrents, the current flowing through them is limited by means of the constant current regulator 17 to a harmless value for these components.

Werden die beiden Eingänge (+) L↑ und (-) L↑ unzulässigerweise mit einem Wechselstromsignal beaufschlagt, so begrenzt der Konstantstromregler 17 den durch die mit den Bezugszeichen 14, 15 und 16 bezeichneten Bauelemente fließenden Strom auf einen Wert, der verhindert, dass beide Standard-Optokoppler 15 durchschalten und sich so undefinierte Schaltungszustände einstellen.If the two inputs (+) L ↑ and (-) L ↑ impermissibly acted upon by an AC signal, the constant current regulator 17 limits the current flowing through the components denoted by the reference numerals 14, 15 and 16 to a value which prevents both Switch through standard optocouplers 15 and thus set undefined circuit states.

Die Erfindung ist nicht auf die beschriebenen Ausführungsbeispiele beschränkt, die auf vielfache Weise abgewandelt werden können.The invention is not limited to the described embodiments, which can be modified in many ways.

So kann die Antriebsvorrichtung 1 einen Antrieb 3 aufweisen, der beim Start ein höheres Losbrechmoment hat.Thus, the drive device 1 may have a drive 3, which has a higher breakaway torque at startup.

Die Antriebsvorrichtung 1 kann weiterhin Mittel aufweisen, die eine Drehzahländerung und/oder eine Drehmomentbegrenzung des Antriebs 3 ermöglichen.The drive device 1 may further comprise means for enabling a speed change and / or a torque limitation of the drive 3.

Weiterhin kann die Antriebsvorrichtung 1 Überlastmittel aufweisen, die eine Überhitzung und Beschädigung durch zu hohe Temperaturen des Antriebs 3 verhindern. Dies kann beispielsweise durch eine Überwachung einer Antriebstemperatur und durch eine Abschaltung des Antriebs 3 im Falle einer zu hohen Antriebstemperatur erreicht werden.Furthermore, the drive device 1 may have overloading means which prevent overheating and damage due to excessive temperatures of the drive 3. This can be done, for example, by monitoring a drive temperature and by switching off the drive 3 in the event of a high drive temperature can be achieved.

In der dargestellten Ausführungsform der Erfindung überträgt das 3-Punkt-Stellsignal sowohl auf der Eingangseite wie auch auf der Ausgangsseite der Anpassungsschaltung 2 Energie und Information mit demselben Signal. Es ist jedoch denkbar, diese Einheit aufzutrennen und getrennte Signale und/oder Übertragungswege zu verwenden. So kann beispielsweise Energie kabelgebunden übertragen werden und (Richtungs)-Information beispielsweise drahtlos.In the illustrated embodiment of the invention, the 3-point actuating signal, both on the input side and on the output side of the matching circuit 2, transmits energy and information with the same signal. However, it is conceivable to separate this unit and to use separate signals and / or transmission paths. For example, energy can be transmitted by cable and (direction) information, for example, wirelessly.

Die offenbarte Anpassungsschaltung 2 kann auch für durch Hydraulik- oder Pneumatikantriebe angetriebene Stellglieder verwendet werden. Es versteht sich, dass in diesem Fall durch elektrische Signale der Anpassungsschaltung 2 schalt- und steuerbare Zwischenglieder, wie beispielsweise Hydraulik- oder Pneumatikventile, zwischengeschaltet sind.The disclosed matching circuit 2 can also be used for actuators driven by hydraulic or pneumatic drives. It is understood that in this case by electrical signals of the matching circuit 2 switchable and controllable intermediate members, such as hydraulic or pneumatic valves, are interposed.
