Description

Die Erfindung betrifft einen Antrieb zum Öffnen und/oder Schließen eines beweglichen Flügels einer Tür oder eines Fensters nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a drive for opening and / or closing a movable wing of a door or a window according to the preamble of patent claim 1.

Gattungsgemäße Antriebe weisen zum Antrieb des beweglichen Flügels eine Antriebseinrichtung auf. Um den Bewegungsbereich des Flügels abzusichern, d.h. sicherzustellen, dass der Flügel rechtzeitig vor einer Kollision mit einem ein Hindernis bildenden Objekt, d.h. einer Person und/oder einem Gegenstand im Bewegungsbereich des Flügels, gestoppt oder reversiert wird, ist eine Steuerungseinrichtung vorhanden zur Ansteuerung der Antriebseinrichtung abhängig von mindestens einem Ausgangssignal einer Sensoreinrichtung, welche den Bewegungsbereich des Türflügels überwacht. Um Störungen der Sensoreinrichtung oder des Datenübertragungsweges zu erkennen und so gegebenenfalls entsprechende Sicherheitsreaktionen, beispielsweise eine Abschaltung der Antriebseinrichtung und/oder ein Alarmsignal, einleiten zu können, ist die Sensoreinrichtung ausgebildet, Statusmeldungen an die Steuerungseinrichtung abzugeben. Es sind Antriebe bekannt, deren Steuerungseinrichtung einen separaten Ausgang für ein Testsignal hat. Dies ist aufwändig.Generic drives have a drive device for driving the movable wing. To secure the range of motion of the wing, i. to ensure that the wing is punctured in time for collision with an obstacle-forming object, i. a person and / or an object in the range of movement of the wing is stopped or reversed, a control device is provided for controlling the drive device depending on at least one output signal of a sensor device which monitors the movement range of the door leaf. In order to detect disruptions of the sensor device or of the data transmission path and thus be able to initiate corresponding safety reactions, for example a shutdown of the drive device and / or an alarm signal, the sensor device is designed to output status messages to the control device. There are known drives whose control device has a separate output for a test signal. This is expensive.

Aus der DE 10 2008 013 982 A1 ist ein Verfahren zur Steuerung eines gattungsgemäßen Antriebs einer Drehflügeltür bekannt. Die Sensoreinrichtung ist mittels eines von der Steuerungseinrichtung generierten, sogenannten Abfragesignals zwischen einem Aktiv- und einem Inaktivmodus umschaltbar. Außerdem ist die Sensoreinrichtung ausgebildet, Statusmeldungen an die Steuerungseinrichtung abzugeben, wobei in einem Automatikbetrieb des Antriebs das Abfragesignal kurzzeitig als Testsignal verwendet wird.From the DE 10 2008 013 982 A1 is a method for controlling a generic drive a swing door known. The sensor device can be switched between an active and an inactive mode by means of a so-called interrogation signal generated by the control device. In addition, the sensor device is designed to send status messages to the control device in an automatic mode of the drive, the interrogation signal is briefly used as a test signal.

Ferner kann bei ähnlichen bekannten Anordnungen das Ausgangssignal der Sensoreinrichtung als Frequenzsignal ausgebildet sein. Hierdurch ist prinzipiell bereits eine hohe Zuverlässigkeit erreicht, jedoch ist es nicht auszuschließen, dass in der Praxis unerwünschte Situationen auftreten können, insbesondere dass durch einen internen Fehler und/oder eine externe Störung ein Signalbild verursacht wird, welches ein korrektes Signal "vortäuscht", was zu einem unsicheren und/oder unzuverlässigen Betriebsverhalten des Antriebs führen kann. Beispielsweise kann bei einem Leitungsbruch eine externe Störquelle eine Schwingung am Eingang der Steuerungseinrichtung anregen, deren Frequenz zumindest nahezu der korrekten Signalfrequenz entspricht. Eine tatsächliche Ansteuerung durch die Sensoreinrichtung würde dann von der Steuerungseinrichtung nicht erkannt.Furthermore, in similar known arrangements, the output signal of the sensor device may be formed as a frequency signal. As a result, a high level of reliability is already achieved in principle, but it can not be ruled out that undesired situations may occur in practice, in particular that a signal image is caused by an internal fault and / or an external fault which "simulates" a correct signal, which can lead to an unsafe and / or unreliable operating behavior of the drive. For example, in the case of a line break, an external interference source can excite a vibration at the input of the control device whose frequency corresponds at least almost to the correct signal frequency. Actual control by the sensor device would then not be recognized by the control device.

Ferner ist aus der DE 10 2007 029 648 A1 eine Sensorvorrichtung für eine automatische Türanlage bekannt. Durch eine Vereinheitlichung der Signale wird durch die Erfindung die Vielzahl von unterschiedlichen Signalvarianten, die von der Steuereinheit verarbeitbar sein müssen, auf ein einziges Signal als Analog- oder Frequenzsignal reduziert, und es sind keine weiteren Prüfanschlüsse an den Sensoren erforderlich. Vorteilhaft wird dazu ein analoges Strom- oder Spannungssignal oder ein Frequenzsignalverwendet.Furthermore, from the DE 10 2007 029 648 A1 a sensor device for an automatic door system known. By standardizing the signals, the invention reduces the multiplicity of different signal variants, which must be processable by the control unit, to a single signal as an analogue or frequency signal, and no further test connections to the sensors are required. Advantageously, an analog current or voltage signal or a frequency signal is used for this purpose.

Der Erfindung liegt die Aufgabe zugrunde, einen Antrieb mit einer Sensoreinrichtung mit einem sicheren und zuverlässigen Betriebsverhalten zu schaffen. Ferner soll der Hard- und Softwareaufwand, insbesondere bei der Steuerungseinrichtung und/oder bei der Signalübertragungsstrecke, minimiert werden.The invention has for its object to provide a drive with a sensor device with a safe and reliable performance. Furthermore, the hardware and software costs, in particular in the control device and / or in the signal transmission path to be minimized.

Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.The object is solved by the features of patent claim 1.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Im Falle einer Detektion eines Objekts wird das Ausgangssignal der Sensoreinrichtung auf eine Detektionsfrequenz umgeschaltet, wobei die Detektionssignalfrequenz signifikant von den Signalfrequenzen abweicht, beispielsweise deutlich kleiner ist als die niedrigste der Signalfrequenzen.In the case of detection of an object, the output signal of the sensor device is switched to a detection frequency, wherein the detection signal frequency deviates significantly from the signal frequencies, for example, is significantly smaller than the lowest of the signal frequencies.

Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

Die Fig. 1 zeigt einen Antrieb 1 mit einer an einer Drehflügeltüranlage montierten Antriebseinrichtung 2. Die Drehflügeltüranlage weist einen Flügel 6 auf, welcher über Scharniere 8 um eine vertikale Drehachse drehbar an einem ortsfesten Türrahmen 7 gelagert ist. Im Gehäuse der Antriebseinrichtung 2, welches im oberen horizontalen Bereich des Türrahmens 7 angeordnet ist, ist ein als Abtriebswelle ausgebildetes Abtriebsglied 3 mit vertikaler Drehachse gelagert, wobei die Enden des Abtriebsglieds 3 aus dem Gehäuse heraus ragen. Am unteren, dem Flügel 6 zugewandten Ende des Abtriebsglieds 3 ist das eine Ende eines als Gleitarm ausgebildeten Kraftübertragungselements 4 drehfest montiert. Das andere Ende des Kraftübertragungselements 4 ist mittels eines Gleiters in einer im Bereich der oberen horizontalen Kante des Flügels 6 montierten Gleitschiene 5 linear verschiebbar geführt. Eine Drehbewegung des Abtriebsglieds 3 der Antriebseinrichtung 2 bewirkt, dass das Kraftübertragungselement 4 verschwenkt wird und über den in der Gleitschiene 5 geführten Gleiter den Flügel 6 bewegt, und umgekehrt.The Fig. 1 shows a drive 1 with a mounted on a swing door system drive device 2. The swing door system has a wing 6, which is mounted on hinges 8 about a vertical axis of rotation rotatably mounted on a stationary door frame 7. In the housing of the drive device 2, which is arranged in the upper horizontal region of the door frame 7, designed as an output shaft output member 3 is mounted with a vertical axis of rotation, wherein the ends of the output member 3 protrude out of the housing. At the bottom, the wing 6 facing the end of the output member 3, the one end of a sliding arm formed as a power transmission element 4 is rotatably mounted. The other end of the power transmission element 4 is guided linearly displaceable by means of a slider in a mounted in the region of the upper horizontal edge of the blade 6 slide rail 5. A rotational movement of the output member 3 of the drive device 2 causes the power transmission element 4 is pivoted and the wing 6 is moved over the slide guided in the slide 5, and vice versa.

Die Antriebseinrichtung 2 weist eine hier nicht dargestellte Steuerungseinrichtung auf, welche den Bewegungsablauf des Antriebs 1 steuert, z.B. abhängig von Sensorsignalen und/oder manuellen Schalthandlungen. Die Steuerungseinrichtung kann eine Speichereinrichtung umfassen, in welcher die zum Betrieb des Antriebs 1 erforderlichen Parameter nichtflüchtig speicherbar sind.The drive device 2 has a control device, not shown here, which controls the movement sequence of the drive 1, for example, depending on sensor signals and / or manual switching operations. The control device may comprise a memory device in which the parameters required for operating the drive 1 can be stored non-volatilely.

Dadurch, dass das Ausgangssignal der Sensoreinrichtung erfindungsgemäß zwischen mindestens zwei Signalfrequenzen umschaltbar ist, solange an der Sensoreinrichtung keine Detektion eines Objekts vorliegt, wobei das Ausgangssignal der Sensoreinrichtung im Falle einer Detektion eines Objekts auf mindestens eine Detektionsfrequenz umschaltbar ist, wird ein sicheres und zuverlässiges Betriebsverhalten des Sensoreinrichtung gewährleistet.Due to the fact that the output signal of the sensor device can be switched over between at least two signal frequencies as long as there is no detection of an object at the sensor device, the output signal of the sensor device being switchable to at least one detection frequency in the event of detection of an object, a reliable and reliable operating behavior of the sensor Sensor device guaranteed.

Hinsichtlich der Steuerungseinrichtung wird kein zusätzlicher Aufwand benötigt, da auf separate, allein für die Testung vorgesehene Ausgänge der Steuerungseinrichtung verzichtet werden kann.With regard to the control device no additional effort is required because it can be dispensed with separate, provided solely for testing outputs of the control device.

Für die Zeitpunkte der Umschaltung zwischen den Signalfrequenzen ist eine Umschaltfrequenz vorgebbar, d.h. jeweils nach einer Umschaltperiodendauer findet periodisch eine Umschaltung des Ausgangssignals der Sensoreinrichtung zwischen den Signalfrequenzen statt.For the times of switching between the signal frequencies, a switching frequency can be predetermined, i. in each case after a switching period period, a switchover of the output signal of the sensor device between the signal frequencies takes place periodically.

Die Detektionssignalfrequenz weicht signifikant von den Signalfrequenzen ab, ist beispielsweise deutlich kleiner als die niedrigste der Signalfrequenzen.The detection signal frequency deviates significantly from the signal frequencies, for example, is significantly smaller than the lowest of the signal frequencies.

The swing door system has a wing 6, which is mounted on hinges 8 about a vertical axis of rotation rotatably mounted on a stationary door frame 7. In the housing of the drive device 2, which is arranged in the upper horizontal region of the door frame 7, designed as an output shaft output member 3 is mounted with a vertical axis of rotation, wherein the ends of the output member 3 protrude out of the housing. At the bottom, the wing 6 facing the end of the output member 3, the one end of a sliding arm formed as a power transmission element 4 is rotatably mounted. The other end of the power transmission element 4 is guided linearly displaceable by means of a slider in a mounted in the region of the upper horizontal edge of the blade 6 slide rail 5. A rotational movement of the output member 3 of the drive device 2 causes the power transmission element 4 is pivoted and the wing 6 is moved over the slide guided in the slide 5, and vice versa.

Die Antriebseinrichtung 2 weist eine hier nicht dargestellte Steuerungseinrichtung auf, welche den Bewegungsablauf des Antriebs 1 steuert, z.B. abhängig von Sensorsignalen und/oder manuellen Schalthandlungen. Die Steuerungseinrichtung kann eine Speichereinrichtung umfassen, in welcher die zum Betrieb des Antriebs 1 erforderlichen Parameter nichtflüchtig speicherbar sind.The drive device 2 has a control device, not shown here, which controls the movement sequence of the drive 1, for example, depending on sensor signals and / or manual switching operations. The control device may comprise a memory device in which the parameters required for operating the drive 1 can be stored non-volatilely.

Eine Sensoreinrichtung 9, welche in diesem Ausführungsbeispiel als im Bereich der oberen horizontalen Kante des Flügels 6 montierte Sensorleiste ausgebildet ist, dient zur Absicherung des Bewegungsbereichs des Flügels 6. Wird ein Objekt, d.h. eine Person und/oder ein Gegenstand im Bewegungsbereich erkannt, wird die Bewegung des Flügels 6 angehalten oder reversiert. Hierzu gibt die Sensoreinrichtung 9 ein das Vorhandensein eines Objekts anzeigendes Signal an die Steuerungseinrichtung der Antriebseinrichtung 2 ab. Die Signalübertragung zwischen der Sensoreinrichtung 9 und der Steuerungseinrichtung kann in bekannter Weise über eine elektrische Signalleitung erfolgen. Alternativ sind auch kabellose Signalübertragungsstrecken denkbar.A sensor device 9, which in this exemplary embodiment is designed as a sensor strip mounted in the region of the upper horizontal edge of the wing 6, serves to secure the range of movement of the wing 6. If an object, i. a person and / or an object detected in the range of motion, the movement of the wing 6 is stopped or reversed. For this purpose, the sensor device 9 outputs a signal indicating the presence of an object to the control device of the drive device 2. The signal transmission between the sensor device 9 and the control device can take place in a known manner via an electrical signal line. Alternatively, wireless signal transmission links are conceivable.

Obwohl zeitgemäße Sensoreinrichtungen 9 bereits eine enorm hohe Zuverlässigkeit aufweisen, sind Störungen der Sensoreinrichtung 9 und/oder der Signalübertragungsstrecke, welche zu einer Kollision des durch die Antriebseinrichtung 2 bewegten Flügels 6 mit einem Hindernis und somit zu Verletzungen und/oder Sachschäden führen können, in der Praxis nicht völlig auszuschließen. Um dieses Risiko zu verringern, ist es sinnvoll, Statusmeldungen der Sensoreinrichtung an die Steuerungseinrichtung zu übermitteln und dort auszuwerten. Entsprechend der zugrundeliegenden Aufgabenstellung soll jedoch eine bereits vorhandene Hardware ohne Änderungen nutzbar sein, d.h. die Steuerungseinrichtung und die Signalübertragungsstrecke sollen keine zusätzlichen Kanäle für die Testung der Sensoreinrichtung benötigen.Although contemporary sensor devices 9 already have an enormously high reliability, disturbances of the sensor device 9 and / or the signal transmission path, which can lead to a collision of the wing 6 moved by the drive device 2 with an obstacle and thus to injuries and / or property damage, in the Practice can not be completely ruled out. To reduce this risk, it makes sense to transmit status messages of the sensor device to the control device and to evaluate there. According to the underlying task, however, an already existing hardware should be usable without changes, i. the control device and the signal transmission path should not require additional channels for the testing of the sensor device.

In der Fig. 2 ist der erfindungsgemäße Ansatz anhand des zeitlichen Verlaufs des Ausgangssignals AS der Sensoreinrichtung 9 bei Nicht-Vorhandensein eines Objekts im Erfassungsbereich der Sensoreinrichtung 9 dargestellt.In the Fig. 2 the approach according to the invention is illustrated by the time profile of the output signal A S of the sensor device 9 in the absence of an object in the detection range of the sensor device 9.

Das Ausgangssignal AS der Sensoreinrichtung 9 wird periodisch zwischen zwei Signalfrequenzen fI, fII umgeschaltet, indem für die Umschaltung zwischen den beiden Signalfrequenzen fI, fII eine Umschaltfrequenz fU vorgegeben ist.The output signal A S of the sensor device 9 is periodically switched between two signal frequencies f I , f II by a switching frequency f U is specified for the switching between the two signal frequencies f I , f II .

Innerhalb einer ersten Umschaltperiodendauer TU = 1/ fU, welche von den Zeitpunkten t0 bis t1 reicht, hat das Ausgangssignal AS der Sensoreinrichtung 9 eine erste Signalperiodendauer TI und somit eine erste Signalfrequenz fI = 1/TI.Within a first switching period T U = 1 / f U , which extends from the times t 0 to t 1 , the output signal A S of the sensor device 9 has a first signal period T I and thus a first signal frequency f I = 1 / T I.

Nach Durchlaufen der ersten Umschaltperiodendauer TU, d.h. zum Zeitpunkt t1, findet eine Umschaltung des Ausgangssignals AS der Sensoreinrichtung 9 auf eine zweite Signalfrequenz fII = 1/TII statt, welche über eine weitere Umschaltperiodendauer TU bis zum Zeitpunkt t2 beibehalten wird.After passing through the first switching period T U , ie at time t 1 , a switchover of the output signal A S of the sensor device 9 takes place at a second signal frequency f II = 1 / T II , which remain over a further switching period T U until the time t 2 becomes.

Nach Durchlaufen der zweiten Umschaltperiodendauer TU, d.h. zum Zeitpunkt t2, wird das Ausgangssignal AS der Sensoreinrichtung 9 wiederum auf die erste Signalfrequenz fI umgeschaltet, welche über eine weitere Umschaltperiodendauer TU bis zum Zeitpunkt t3 beibehalten wird, und vom Zeitpunkt t3 bis zum Zeitpunkt t4 ist über eine weitere Umschaltperiodendauer TU wiederum die zweite Signalfrequenz fII wirksam, usw.After passing through the second switching period T U , ie at time t 2 , the output signal A S of the sensor device 9 is in turn switched to the first signal frequency f I , which is maintained over a further switching period T U until the time t 3 , and from the time t 3 until time t 4 , the second signal frequency f II is again active over a further switching period T U , etc.

D.h. jeweils nach einer Umschaltperiodendauer TU findet periodisch eine Umschaltung des Ausgangssignals AS der Sensoreinrichtung 9 zwischen den beiden Signalfrequenzen fI, fII statt.That is, in each case after a switching period T U is periodically a switching of the output signal A S of the sensor device 9 between the two signal frequencies f I , f II instead.

Diese beiden Signalfrequenzen fI, fII sind periodisch abwechselnd wirksam, solange an der Sensoreinrichtung 9 keine Detektion eines Objekts vorliegt.These two signal frequencies f I , f II are periodically alternately effective as long as there is no detection of an object at the sensor device 9.

Im Falle einer Detektion eines Objekts im Erfassungsbereich der Sensoreinrichtung 9 findet umgehend eine Umschaltung des Ausgangssignals AS der Sensoreinrichtung 9 auf eine Detektionssignalfrequenz fD statt, wobei die Detektionssignalfrequenz fD signifikant von den beiden Signalfrequenzen fI, fII abweicht. Wenn das Ausgangssignals AS der Sensoreinrichtung 9 mit Detektionssignalfrequenz fD erfasst wird, wird eine entsprechende Reaktion der Antriebseinrichtung 2 eingeleitet, z.B. ein Stoppen oder Reversieren des Türflügels 6.In the case of detection of an object in the detection range of the sensor device 9, a switchover of the output signal A S of the sensor device 9 to a detection signal frequency f D takes place immediately, wherein the detection signal frequency f D differs significantly from the two signal frequencies f I , f II . If the output signal A S of the sensor device 9 is detected with the detection signal frequency f D , a corresponding reaction of the drive device 2 is initiated, for example stopping or reversing of the door leaf 6.

Dieses Schema der periodischen Umschaltung zwischen den beiden Signalfrequenzen fI, fII ist in der Steuerungseinrichtung der Antriebseinrichtung 2 als Referenzschema hinterlegt. D.h. in der Steuerungseinrichtung wird das Ausgangssignal AS der Sensoreinrichtung 9 permanent dahingehend überprüft, ob mit der Umschaltfrequenz fU eine periodische Umschaltung zwischen den beiden Signalfrequenzen fI, fII stattfindet, sowie ob die Detektionssignalfrequenz fD vorliegt.This scheme of periodic switching between the two signal frequencies f I , f II is stored in the control device of the drive device 2 as a reference scheme. That is, in the control device, the output signal A S of the sensor device 9 is constantly checked to see whether with the switching frequency f U a periodic switching between the two signal frequencies f I , f II takes place, as well as whether the detection signal frequency f D is present.

Die Sensoreinrichtung 9 wird als ordnungsgemäß funktionierend eingestuft, wenn sowohl die erfasste Umschaltfrequenz fU als auch die beiden erfassten Signalfrequenzen fI, fII den hinterlegten Referenzwerten zumindest annähernd entsprechen.The sensor device 9 is classified as functioning properly if both the detected switching frequency f U and the two detected signal frequencies f I , f II at least approximately correspond to the stored reference values.

Ein Zahlenbeispiel soll dies nachfolgend verdeutlichen, wobei folgende Werte angenommen werden: erste Signalfrequenz fI = 100 Hz, zweite Signalfrequenz fII = 150 Hz, Umschaltfrequenz fU = 0,83 Hz, Detektionssignalfrequenz fD = 5 Hz.A numerical example is intended to clarify this below, the following values being assumed: first signal frequency f I = 100 Hz, second signal frequency f II = 150 Hz, switching frequency f U = 0.83 Hz, detection signal frequency f D = 5 Hz.

Falls für das Ausgangssignal AS der Sensoreinrichtung 9 eine Frequenz von weniger als 10 Hz erfasst wird, wird daraus das Vorliegen einer Detektion geschlossen, und der Türflügel 6 wird durch die Antriebseinrichtung 2 gestoppt oder reversiert. Wird für das Ausgangssignal AS der Sensoreinrichtung 9 eine Frequenz zwischen 10 Hz und 70 Hz oder von mehr als 200 Hz erfasst, so wird daraus das Vorliegen einer Störung geschlossen und die entsprechende Sicherheitsreaktion der Antriebseinrichtung 2 eingeleitet. Ebenso, wenn die Frequenz des erfassten Ausgangssignals AS der Sensoreinrichtung 9 über mehr als zwei Sekunden konstant bleibt.If a frequency of less than 10 Hz is detected for the output signal A S of the sensor device 9, the presence of a detection is concluded therefrom and the door leaf 6 is stopped or reversed by the drive device 2. If a frequency between 10 Hz and 70 Hz or more than 200 Hz is detected for the output signal A S of the sensor device 9, the presence of a fault is concluded and the corresponding safety reaction of the drive device 2 initiated. Likewise, when the frequency of the detected output signal A S of the sensor device 9 remains constant for more than two seconds.

Dagegen wird die Sensoreinrichtung 9 bei einer Frequenz des erfassten Ausgangssignals AS zwischen 70 und 200 Hz, welche innerhalb von höchstens zwei Sekunden auf einen anderen Frequenzwert ebenfalls zwischen 70 und 200 Hz wechselt, als ordnungsgemäß funktionierend, jedoch im Ruhezustand befindlich, d.h. ohne vorliegende Detektierung eines Objekts eingestuft.In contrast, the sensor device 9 at a frequency of the detected output signal A S between 70 and 200 Hz, which also within a maximum of two seconds to another frequency value between 70 and 200 Hz changes, as properly functioning, but at rest, ie without detection of an object.

Bei diesem Zahlenbeispiel sind also Toleranzbereiche definiert, um Situationen, dass eine ordnungsgemäß funktionierende Sensoreinrichtung 9 fälschlicherweise als defekt eingestuft wird, wenn die erfassten Frequenzen fI, fII, fU, fD leicht von den Referenzwerten abweichen, zu vermeiden. Die Breiten der Toleranzbereiche sind selbstverständlich auch größer oder kleiner wählbar.In this numerical example, tolerance ranges are defined in order to avoid situations in which a properly functioning sensor device 9 is erroneously classified as defective if the detected frequencies f I , f II , f U , f D deviate slightly from the reference values. The widths of the tolerance ranges are of course also larger or smaller selectable.

Abweichend von dem dargestellten Ausführungsbeispiel, welches mit zwei Signalfrequenzen fI, fII sowie einer Umschaltfrequenz fU und einer Detektionssignalfrequenz fD die einfachste Ausgestaltung der erfindungsgemäßen Idee darstellt, sind selbstverständlich auch Ausführungen denkbar, bei denen drei oder mehr verschiedene Signalfrequenzen und/oder zwei oder mehr verschiedene Umschaltfrequenzen und/oder zwei oder mehr verschiedene Detektionssignalfrequenzen, mit entsprechendem Referenzschema, verwendet werden.Notwithstanding the illustrated embodiment, which with two signal frequencies f I , f II and a switching frequency f U and a detection signal frequency f D represents the simplest embodiment of the inventive idea, are Of course, embodiments conceivable in which three or more different signal frequencies and / or two or more different switching frequencies and / or two or more different detection signal frequencies are used with a corresponding reference scheme.
