The controller separates the door drive from the electrical supply in an operating mode, and an electrical energy storage (3) supplies the electrical energy. The controller connects the door drive with the electrical supply in another operating mode, and is switched into the latter operating mode when the drive motor is moved. The energy storage is supercharged in the latter operating mode.

Description

Die vorliegende Erfindung betrifft einen Torantrieb mit elektrisch betriebenen Komponenten, welche über einen Netzanschluß mit elektrischer Energie versorgt werden. Üblicherweise weist der Torantrieb dabei eine elektronische Steuerung sowie einen elektrischen Antriebsmotor auf, welche zu ihrem Betrieb elektrische Energie benötigen.The present invention relates to a door drive with electrically operated components, which are supplied via a network connection with electrical energy. Usually, the door drive has an electronic control and an electric drive motor, which require electrical energy for their operation.

Der Antrieb und dessen Steuerung sind bei bekannten Antrieben üblicherweise permanent mit dem Stromnetz verbunden, so dass ständig Leistung aufgenommen wird. Insbesondere wenn ein Transformator zum Einsatz kommt, um sowohl den Elektromotor als auch die Steuerung mit elektrischer Energie zu versorgen, ist dieser jedoch auf die Leistungsaufnahme während der Betriebszeiten des Elektromotors ausgelegt. Wird der Elektromotor nicht betrieben, wird damit häufig Energie verschwendet.The drive and its control are usually permanently connected to the power supply in known drives, so that power is constantly being absorbed. In particular, when a transformer is used to supply both the electric motor and the controller with electrical energy, but this is designed for the power consumption during the operating times of the electric motor. If the electric motor is not operated, energy is often wasted.

Die aktiven Betriebszeiten von Torantrieben, d.h. die Betriebszeiten des Elektromotors des Antriebs, betragen aber fast immer nur wenige Minuten, wobei ein Öffnungszyklus häufig auch nur zwanzig Sekunden benötigt. Während der übrigen inaktiven Betriebszeiten wird dagegen lediglich elektrische Energie für die Steuerung benötigt, während der erheblich größere Energieverbrauch für den Antriebsmotor wegfällt.The active operating times of gate drives, ie the operating times of the electric motor of the drive, but almost always only a few minutes, with an opening cycle often requires only twenty seconds. During the remaining inactive operating times, however, only electrical energy for the controller needed while the significantly greater energy consumption for the drive motor is eliminated.

Zur Reduzierung der Energieverluste während der inaktiven Betriebsphasen werden häufig zwei Transformatoren, einer für den inaktiven Modus und ein zweiter zuschaltbarer für den aktiven Betriebsmodus eingesetzt. Als Sonderform kann auch wie in EP 6 256 26 beschrieben ein besonderer Transformator mit zwei Wicklungen für die jeweiligen Betriebsarten eingesetzt werden.To reduce energy losses during inactive operating phases, two transformers are often used, one for the inactive mode and a second switchable for the active operating mode. As a special form can also as in EP 6 256 26 described a special transformer with two windings for the respective operating modes are used.

Solche Lösungen sind jedoch konstruktiv aufwendig und können den Energieverbrauch während der inaktiven Betriebsphasen dennoch nicht auf ein zufriedenstellendes Niveau senken.However, such solutions are structurally complex and can not reduce the energy consumption during the inactive operating phases yet to a satisfactory level.

Aufgabe der vorliegenden Erfindung ist es daher, einen Torantrieb mit reduziertem Energieverbrauch insbesondere während der inaktiven Betriebszeiten zur Verfügung zu stellen. Vorteilhafterweise soll dies auf einfache und kostengünstige Weise gelöst werden.The object of the present invention is therefore to provide a door drive with reduced energy consumption, in particular during inactive operating times. Advantageously, this should be solved in a simple and cost-effective manner.

Erfindungsgemäß wird diese Aufgabe von einem Torantrieb gemäß Anspruch 1 gelöst. Ein solcher Torantrieb mit elektrisch betriebenen Komponenten, welche über einen Netzanschluß mit elektrischer Energie versorgt werden, weist erfindungsgemäß eine Steuerung und einen elektrischen Energiespeicher auf, wobei in einem ersten Betriebsmodus die Steuerung den Torantrieb vom Netz trennt und der elektrische Energiespeicher die elektrische Energie bereitstellt und in einem zweiten Betriebsmodus die Steuerung den Torantrieb mit dem Netz verbindet. Erfindungsgemäß läßt sich so die Leistungsaufnahme des Torantriebs nochmals erheblich vermindern, wobei Messungen gegenüber herkömmlichen Lösungen mit zwei Transformatoren eine Reduktion auf ein Zehntel des üblicherweise benötigten Jahresverbrauchs an Energie belegen.According to the invention, this object is achieved by a door drive according to claim 1. Such a door drive with electrically operated components, which are supplied via a network connection with electrical energy, according to the invention has a controller and an electrical energy storage, in a first operating mode, the control separates the door drive from the network and the electrical energy storage provides the electrical energy and in a second operating mode, the controller connects the door drive with the network. According to the invention, the power consumption of the door drive can be significantly reduced again, with measurements over conventional solutions with two transformers occupying a reduction to one-tenth of the energy consumption usually required per year.

Durch den integrierten Energiespeicher besteht dabei nämlich die Möglichkeit, den Antrieb zeitweise komplett vom Stromnetz zu trennen. Während dieser Zeit wird keine Energie aus dem Stromnetz benötigt, da diese von dem Energiespeicher zur Verfügung gestellt wird. Der integrierte Energiespeicher kann dabei optimal auf den inaktiven Modus ausgelegt werden, und zwar mit einem sehr viel besseren Wirkungsgrad als ein Netzteil.Because of the integrated energy storage, it is possible to temporarily disconnect the drive completely from the power grid. During this time will be no energy from the power grid needed, as it is provided by the energy storage. The integrated energy storage can be optimally designed for the inactive mode, with a much better efficiency than a power supply.

Weiterhin vorteilhafterweise wird dabei der Torantrieb in Phasen, in welchen der Antriebsmotor nicht bewegt wird, im ersten Betriebsmodus betrieben. Der erste Betriebsmodus entspricht damit dem inaktiven Betriebsmodus des Torantriebs, bei welchem lediglich die Steuerung mit Energie versorgt werden muß, nicht aber der Antriebsmotor, da das Tor nicht bewegt wird. Der in dieser Phase sehr viel kleinere Energieverbrauch kann nun problemlos durch den elektrischen Energiespeicher bereitgestellt werden, ohne dass der Torantrieb mit dem Netz verbunden sein müßte.Furthermore advantageously, the door drive is operated in phases in which the drive motor is not moved in the first operating mode. The first operating mode thus corresponds to the inactive operating mode of the door drive, in which only the controller must be supplied with energy, but not the drive motor, since the gate is not moved. The much smaller energy consumption in this phase can now be easily provided by the electrical energy storage, without the door drive would have to be connected to the network.

Weiterhin vorteilhafterweise schaltet die Steuerung in den zweiten Betriebsmodus, wenn der Antriebsmotor bewegt wird. So kann der erheblich größere Energieverbrauch des Antriebsmotors über den Netzanschluß bereit gestellt werden.Further advantageously, the controller switches to the second operating mode when the drive motor is being moved. Thus, the much greater power consumption of the drive motor can be provided via the power supply.

Weiterhin vorteilhafterweise wird der elektrische Energiespeicher dabei im zweiten Betriebsmodus aufgeladen. Der Energiespeicher kann damit während der Betriebszyklen des Antriebsmotors, während welchen der Torantrieb ohnehin mit dem Netz verbunden ist, aufgeladen werden.Further advantageously, the electrical energy store is charged in the second operating mode. The energy storage can thus be charged during the operating cycles of the drive motor, during which the door drive is already connected to the network anyway.

Weiterhin vorteilhafterweise weist der Torantrieb zudem eine Ladesteuerung auf, welche unabhängig vom Betriebszustand des Antriebsmotors in den zweiten Betriebsmodus schaltet, um den elektrischen Energiespeicher aufzuladen. Hierdurch kann der Energiespeicher kurzfristig nachgeladen werden; wenn die aktiven Betriebsphasen des Torantriebs für die Ladung des Energiespeichers nicht ausreichen. Die Ladesteuerung schaltet dann in den zweiten Betriebsmodus, in welchem der Torantrieb mit dem Netz verbunden ist, und lädt den Energiespeicher auf.Further advantageously, the door drive also has a charging control, which switches independently of the operating state of the drive motor in the second operating mode to charge the electrical energy storage. As a result, the energy storage can be recharged at short notice; if the active operating phases of the door drive are insufficient for charging the energy store. The charging controller then switches to the second operating mode, in which the door drive is connected to the mains, and charges the energy store.

Vorteilhafterweise schaltet die Ladesteuerung dabei in Abhängigkeit vom Ladezustand des elektrischen Energiespeichers in den zweiten Betriebsmodus. Die Ladesteuerung umfaßt also eine Überwachung des Ladezustands des Energiespeichers und lädt diesen nach, wenn der Ladezustand unter einen gewissen Wert gefallen ist. Das Laden des elektrischen Energiespeichers erfolgt damit als Funktion des Ladezustandes.Advantageously, the charge controller switches in dependence on the state of charge of the electrical energy storage in the second operating mode. The charging control thus includes a monitoring of the state of charge of the energy storage and recharges this when the state of charge has fallen below a certain value. The charging of the electrical energy storage is thus carried out as a function of the state of charge.

Alternativ kann die Ladesteuerung auch in Abhängigkeit von der seit dem letzten Ladezyklus verstrichenen Zeitspanne in den zweiten Betriebsmodus schalten. Da der maximale Energiebedarf im inaktiven Betrieb bekannt ist (worst case), läßt sich die minimale Zeitdauer ohne Nachladen des Energiespeichers bestimmen. Wird während dieser Zeit nicht ohnehin in den zweiten Betriebsmodus geschaltet, weil der Antriebmotor bewegt wird, so schaltet die Ladesteuerung nach Ablauf dieser Zeitspanne unabhängig vom Betriebszustand des Antriebsmotors in den zweiten Betriebsmodus, um den Energiespeicher nachzuladen. Das Laden des elektrischen Energiespeichers erfolgt damit als Funktion der Zeit.Alternatively, the charge control may also switch to the second operating mode depending on the time elapsed since the last charge cycle. Since the maximum energy requirement in inactive operation is known (worst case), the minimum time can be determined without recharging the energy storage. If not switched to the second operating mode during this time, because the drive motor is moved, the charging control switches after this time, regardless of the operating state of the drive motor in the second operating mode to recharge the energy storage. The charging of the electrical energy storage is done as a function of time.

Weiterhin vorteilhafterweise weist der erfindungsgemäße Torantrieb ein Netzteil auf, welches mit dem Netzanschluß verbunden oder vom Netzanschluß getrennt wird, um von einem Betriebsmodus in den anderen Betriebsmodus zu schalten. Gerade für solche Torantriebe, bei welchen die elektrisch betriebenen Komponenten über ein Netzteil mit elektrischer Energie versorgt werden, ergibt die erfindungsgemäße Steuerung eine besonders große Energieeinsparung, da das Netzteil in seinem Wirkungsgrad wesentlich schlechter auf die inaktiven Betriebsphasen ausgelegt werden kann als die erfindungsgemäße Steuerung mit dem elektrischen Energiespeicher.Further advantageously, the door drive according to the invention comprises a power supply, which is connected to the power supply or disconnected from the power supply to switch from one operating mode to the other operating mode. Especially for such door drives, in which the electrically operated components are supplied via a power supply with electrical energy, the control of the invention results in a particularly large energy savings, since the power supply can be designed significantly inferior in its efficiency to the inactive operating phases as the inventive control with the electrical energy storage.

Weiterhin vorteilhafterweise kommt die erfindungsgemäße Steuerung dabei bei einem Torantrieb zum Einsatz, welcher einen elektrischen Antriebsmotor aufweist, der von dem Netzteil mit elektrischer Energie versorgt wird. Das Netzteil muß bei solchen Antrieben während der aktiven Betriebsphasen, in welchen der Antriebsmotor bewegt wird, sehr viel elektrische Energie zur Verfügung stellen, und in inaktiven Betriebsphasen, in welchen der Antriebsmotor nicht bewegt wird, nur sehr wenig. Die erfindungsgemäße Steuerung mit dem elektrischen Energiespeicher kann hier gegenüber dem Stand der Technik eine enorme Reduktion des Energieverbrauchs bewirken.Further advantageously, the control according to the invention is used in a door drive which has an electric drive motor which is supplied with electrical energy by the power supply. In such drives, the power supply must provide a great deal of electrical energy during active operating phases in which the drive motor is moved, and inactive ones Operating phases in which the drive motor is not moved, only very little. The control according to the invention with the electrical energy storage device can bring about a huge reduction in energy consumption compared to the prior art.

Die vorliegende Erfindung wird nun anhand von Ausführungsbeispielen und Zeichnungen näher dargestellt.The present invention will now be described in more detail with reference to embodiments and drawings.

Figur 1 zeigt ein Ausführungsbeispiel des erfindungsgemäßen Torantriebs, bei welchem eine Steuerung 2 und ein Antriebsmotor 10 mit elektrischer Energie versorgt werden müssen. Der Torantrieb kann hierfür mit einer Netzversorgung 1 verbunden werden, welche elektrische Energie zur Verfügung stellt. FIG. 1 shows an embodiment of the door drive according to the invention, in which a controller 2 and a drive motor 10 must be supplied with electrical energy. The door drive can be connected to a power supply 1, which provides electrical energy.

Dabei ist ein Transformator 5 vorgesehen, welcher über einen Schalter 4 mit der Netzversorgung 1 verbunden bzw. von der Netzversorgung 1 getrennt werden kann. Der Transformator 5 stellt dabei die elektrische Energie zur Verfügung, mit welcher die Steuerung 2 und der Antriebsmotor 10 betrieben werden. Der Transformator ist deshalb auf die Leistungsaufnahme während der aktiven Betriebsphasen des Torantriebs ausgelegt, während welcher der Antriebsmotor 10 das Tor bewegt.In this case, a transformer 5 is provided, which can be connected via a switch 4 to the mains supply 1 or disconnected from the mains supply 1. The transformer 5 provides the electrical energy with which the controller 2 and the drive motor 10 are operated. The transformer is therefore designed for the power consumption during the active operating phases of the door drive during which the drive motor 10 moves the door.

Um während inaktiver Betriebsphasen, währen welcher der Antriebsmotor 10 nicht bewegt wird und damit die Leistungsaufnahme des gesamten Systems erheblich niedriger liegt als die Leistungsaufnahme, auf welche der Transformator 5 ausgelegt ist, ist ein Energiespeicher 3 vorgesehen. Die Steuerung 2 trennt nun in inaktiven Phasen durch Ansteuerung des Schalters 4 den Transformator 5 vom Netz, so dass der gesamte Torantrieb von der Netzversorgung komplett getrennt ist. Während dieses ersten Betriebsmodus wird die elektrische Energie für die Steuerung über den Energiespeicher 3 zur Verfügung gestellt. Als Energiespeicher kann z.B. ein Akkumulator oder ein Kondensator verwendet werden kann.In order during inactive operating phases, during which the drive motor 10 is not moved and thus the power consumption of the entire system is considerably lower than the power consumption to which the transformer 5 is designed, an energy storage 3 is provided. The controller 2 separates now in inactive phases by driving the switch 4, the transformer 5 from the network, so that the entire door drive is completely disconnected from the mains supply. During this first operating mode, the electrical energy for the control via the energy storage 3 is provided. As energy storage, e.g. an accumulator or a capacitor can be used.

Die Steuerung 2 kann nun von diesem ersten Betriebsmodus in einen zweiten Betriebsmodus schalten, indem sie den Schalter 4 schließt und so den Transformator 5 mit der Netzversorgung 1 verbindet. Insbesondere schaltet die Steuerung 2 in diesen zweiten Betriebsmodus, wenn der Antriebsmotor 10 bewegt werden soll, um die dann erheblich höhere Leistungsaufnahme über die Netzversorgung 1 zur Verfügung zu stellen.The controller 2 can now switch from this first operating mode to a second operating mode by closing the switch 4 and thus connecting the transformer 5 to the mains supply 1. In particular, the controller 2 switches to this second operating mode when the drive motor 10 is to be moved in order to provide the then considerably higher power consumption via the mains supply 1.

Der Energiespeicher 3 ist dagegen auf den inaktiven Betrieb ausgelegt, während welchem der Antriebsmotor 10 nicht bewegt wird, so dass nur die Steuerung 2 mit Energie versorgt werden muß. Während des ersten Betriebsmodus wird damit die elektrische Energie vom Energiespeicher bereitgestellt, welcher sich hierdurch entlädt. Schaltet die Steuerung dagegen in den zweiten Betriebsmodus, weil das Tor durch den Antriebsmotor 10 bewegt werden soll, wird gleichzeitig der Energiespeicher 3 über die von der Netzversorgung 1 zur Verfügung gestellte elektrische Energie aufgeladen.The energy storage 3, however, is designed for inactive operation, during which the drive motor 10 is not moved, so that only the controller 2 must be supplied with energy. During the first operating mode, the electrical energy is thus provided by the energy store, which thereby discharges. On the other hand, if the controller switches to the second operating mode because the door is to be moved by the drive motor 10, the energy store 3 is simultaneously charged via the electrical energy provided by the mains supply 1.

Die erfindungsgemäße Steuerung 2 weist weiterhin eine Ladesteuerung auf, welche unabhängig vom Betriebszustand des Antriebsmotors 10 in den zweiten Betriebsmodus schaltet, um den elektrischen Energiespeicher aufzuladen. Hierdurch wird sichergestellt, dass der Energiespeicher auch dann geladen wird, wenn der Antriebsmotor 10 über lange Betriebszeiten nicht bewegt wird.The controller 2 according to the invention also has a charge control, which switches independently of the operating state of the drive motor 10 in the second operating mode to charge the electrical energy storage. This ensures that the energy store is also charged when the drive motor 10 is not moved over long periods of operation.

In Figuren 2 und 3 sind ein erstes und ein zweites Ausführungsbeispiel einer solchen Ladesteuerung gezeigt, bei welcher die Ladung als Funktion des Ladezustands bzw. der Zeit erfolgt. Die Grafik zeigt dabei den Ladezustand des elektrischen Energiespeichers 3, welcher z.B. anhand der vom Energiespeicher zur Verfügung gestellten Spannung bestimmt werden kann, in Abhängigkeit von der Zeit. Unterhalb des Diagramms ist zudem angezeigt, ob der Torantrieb mit der Netzversorgung verbunden ist oder nicht, d.h. ob der Torantrieb in dem ersten Betriebsmodus 6 ist, in welchem der Antrieb von der Netzversorgung getrennt ist und die elektrische Energie vom elektrischen Energiespeicher zur Verfügung gestellt wird, oder im zweiten Betriebsmodus 7, während welchem der Torantrieb mit der Netzversorgung 1 verbunden ist.In Figures 2 and 3 show a first and a second embodiment of such a charge control, in which the charge takes place as a function of the state of charge or the time. The graph shows the state of charge of the electrical energy storage device 3, which can be determined, for example, based on the voltage provided by the energy storage, as a function of time. Below the diagram is also indicated whether the door drive is connected to the mains supply or not, ie whether the door drive in the first operating mode 6, in which the drive is disconnected from the mains supply and the electrical energy is provided by the electrical energy storage, or in the second operating mode 7, during which the door drive is connected to the mains supply 1.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel der Ladesteuerung erfolgt dabei die Ladung als Funktion des Ladezustands. Fällt die Ladung des Energiespeichers unter eine Einschaltschwelle, schaltet die Ladesteuerung automatisch aus dem ersten Betriebsmodus 6 in den zweiten Betriebsmodus 7, indem sie den erfindungsgemäßen Torantrieb mit dem Netz verbindet. Hierdurch wird der elektrische Energiespeicher über die Netzversorgung 1 aufgeladen. Ist der elektrische Energiespeicher geladen, schaltet die Ladesteuerung wieder zurück in den ersten Betriebsmodus und trennt den erfindungsgemäßen Torantrieb von der Netzversorgung, so dass die elektrische Energie wieder vom elektrischen Energiespeicher zur Verfügung gestellt wird, welcher sich hierdurch wieder entlädt. Typische Ladezyklen bestehen damit aus einer langen Betriebszeit im ersten Betriebsmodus 6, an welche sich eine kurze Betriebszeit im zweiten Betriebsmodus 7 anschließt. Schaltet die Steuerung unabhängig von der eigentlichen Ladesteuerung in den zweiten Betriebsmodus, da der Antriebsmotor 10 bewegt werden soll, wird der Energiespeicher ebenfalls geladen, so dass hierdurch ein neuer Zyklus beginnt.At the in FIG. 2 illustrated embodiment of the charging control takes place while the charge as a function of state of charge. If the charge of the energy store falls below a switch-on threshold, the charge controller automatically switches from the first operating mode 6 into the second operating mode 7 by connecting the door drive according to the invention to the grid. As a result, the electrical energy storage is charged via the mains supply 1. If the electrical energy store is charged, the charge controller switches back to the first operating mode and disconnects the door drive according to the invention from the mains supply, so that the electrical energy is again made available by the electrical energy store, which thereby discharges again. Typical charging cycles thus consist of a long operating time in the first operating mode 6, which is followed by a short operating time in the second operating mode 7. Switches the controller regardless of the actual charge control in the second mode of operation, since the drive motor 10 is to be moved, the energy storage is also charged, thereby starting a new cycle.

Figur 3 zeigt nun eine alternative Ausführung der erfindungsgemäßen Ladesteuerung, bei welcher die Ladung als Funktion der Zeit erfolgt. Da der maximale Energiebedarf im inaktiven Modus bekannt ist, läßt sich die minimale Zeitdauer ohne Nachladen des Energiespeichers bestimmen. Wird während dieser Zeit der zweite Betriebsmodus, in welchem der Energiespeicher nachgeladen wird, nicht ohnehin aufgrund eines Betriebs des Antriebsmotors 10 aktiviert, so schaltet die Ladesteuerung zum Nachladen in den zweiten Betriebsmodus. Auch hierdurch kann sichergestellt werden, dass die vom Energiespeicher zur Verfügung gestellte Systemspannung eine minimal zulässige Systemspannung nicht unterschreitet. FIG. 3 now shows an alternative embodiment of the charging controller according to the invention, in which the charge takes place as a function of time. Since the maximum energy requirement in the inactive mode is known, the minimum time can be determined without recharging the energy storage. Will be the second during this time Operating mode, in which the energy storage is recharged, not already activated due to an operation of the drive motor 10, so the charging control switches to recharge in the second operating mode. This also makes it possible to ensure that the system voltage provided by the energy store does not fall below a minimum permissible system voltage.

Durch die komplette Trennung des erfindungsgemäßen Torantriebs vom Stromnetz während eines Großteils der Betriebszeit läßt sich dabei die Leistungsaufnahme des erfindungsgemäßen Torantriebs über den Zeitraum eines Jahres betrachtet auf ca. ein Zehntel der üblicherweise benötigten Energiemenge reduzieren. Hierdurch ergibt sich eine erhebliche Energiekostenersparnis und ein verbesserter Umweltschutz.As a result of the complete separation of the door drive according to the invention from the power supply during a large part of the operating time, the power consumption of the door drive according to the invention over the period of one year can be reduced to approximately one tenth of the amount of energy usually required. This results in a significant energy cost savings and improved environmental protection.

Der integrierte Energiespeicher der vorliegenden Erfindung kann dabei in seinem Wirkungsgrad optimal auf den inaktiven Modus ausgelegt werden, was während der inaktiven Betriebszeiten sehr viel effizienter ist als die Energieversorgung durch ein Netzteil. Der Energiespeicher wird dann während der aktiven Betriebszyklen, während welcher der Antriebsmotor 10 bewegt wird und der erfindungsgemäße Torantrieb ohnehin mit der Netzversorgung verbunden ist, geladen. Reicht dies nicht aus, da der Torantrieb nicht oft genug aktiviert wird, greift die erfindungsgemäße Ladesteuerung ein, welche wenn nötig den elektrischen Energiespeicher über die Netzversorgung nachlädt.The integrated energy storage of the present invention can be optimally designed in its efficiency to the inactive mode, which is much more efficient during the inactive operating times than the power supply by a power supply. The energy storage device is then charged during the active operating cycles during which the drive motor 10 is moved and the door drive according to the invention is in any case connected to the mains supply. If this is insufficient, since the door drive is not activated often enough, the charging control according to the invention intervenes, which, if necessary, recharges the electrical energy store via the mains supply.
