Description

Die Erfindung betrifft eine Ansteuerelektronik für einen mit Gleichstrom betriebenen Türöffner, eine Versorgungseinheit für einen mit Gleichstrom betriebenen Türöffner und ein Verfahren zum Ansteuern eines mit Gleichstrom betriebenen Türöffners.The invention relates to control electronics for a direct current operated door opener, a supply unit for one with direct current operated door opener and a method for controlling a direct current operated door opener.

Allgemein können elektrische Türöffner mit Gleichstrom oder mit Wechselstrom angesteuert werden. Bei einer Ansteuerung mit Wechselstrom entsteht ein Brummton, der als störend empfunden wird, insbesondere wenn die angesteuerte Tür für eine längere Zeit, z. B. mehrere Stunden, entriegelt werden soll. Bei einer Ansteuerung mit Gleichstrom führt schon eine sehr geringe Vorlast auf die Türöffner-Falle dazu, dass sich der Türöffner verklemmt und die Tür nicht freigegeben wird. Schon die durch eine Türdichtung hervorgerufene Vorlast kann ausreichen, den Türöffner zu verklemmen, was dazu führt, dass die Tür nicht geöffnet wird.In general, electric strikes can be operated with direct current or with alternating current can be controlled. When activated with alternating current a humming sound that is perceived as disturbing, especially when the controlled door for a long time, e.g. B. unlocked for several hours shall be. When controlled with direct current, one leads very low preload on the door opener latch causing the door opener jammed and the door is not released. Already through a door seal caused preload can be sufficient to jam the door opener, which results in the door not opening.

Es ist daher die der Erfindung zugrunde liegende Aufgabe, eine Ansteuerung für einen Türöffner bereitzustellen, bei dem die zuvor beschriebenen Nachteile nicht existieren.It is therefore the task underlying the invention, a control to provide for a door opener in which the previously described Disadvantages do not exist.

Diese Aufgabe wird erfindungsgemäß durch eine Ansteuerelektronik für einen mit Gleichstrom betriebenen Türöffner nach dem Patentanspruch 1 gelöst. Vorteilhafte Weiterbildungen finden sich in den diesen nachgeordneten Unteransprüchen. Weiter wird diese Aufgabe durch eine im Patentanspruch 15 definierte Versorgungseinheit für einen mit Gleichstrom betriebenen Türöffner und ein Verfahren zum Ansteuern eines mit Gleichstrom betriebenen Türöffners gelöst, wie es im Patentanspruch 16 angegeben ist. Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind in den diesen nachgeordneten Unteransprüchen angegeben.This object is achieved by control electronics for a door opener operated with direct current according to claim 1 solved. Advantageous further developments can be found in the subordinate ones Dependent claims. This object is further achieved by a claim 15 defined supply unit for one operated with direct current Door opener and a method for controlling one with direct current operated door opener solved, as specified in claim 16 is. Advantageous further developments of the method according to the invention are specified in the subordinate claims.

Eine Ansteuerelektronik für einen mit Gleichstrom betriebenen Türöffner weist erfindungsgemäß eine Bestromungsvorrichtung auf, die eine an den Türöffner angelegte Gleichspannung zumindest während eines bestimmten Zeitabschnittes der Bestromung des Türöffners pulst oder pulsen kann.Control electronics for a door opener operated with direct current According to the invention has an energization device which is connected to the Door opener applied DC voltage at least during a certain one Period of the energization of the door opener pulses or pulses can.

Dementsprechend weist ein erfindungsgemäßes Verfahren zum Ansteuern eines mit Gleichstrom betriebenen Türöffners ein zumindest während eines bestimmten Zeitabschnittes der Bestromung des Türöffners erfolgendes oder mögliches Pulsen einer an den Türöffner angelegten Gleichspannung auf.Accordingly, an inventive method for driving of a door opener operated with DC at least during a certain period of time for energizing the door opener or possible pulsing of a DC voltage applied to the door opener on.

Damit wird erfindungsgemäß die mögliche Vorlast bei mit Gleichstrom betriebenen Türöffnern erhöht, ohne dass ein entsprechend einer Wechselstrombestromung entstehender Brummton auftritt.Thus, according to the invention, the possible preload when operated with direct current Door openers increased without a corresponding AC power humming sound occurs.

Nach der Erfindung liegt der bestimmte Zeitabschnitt vorteilhafter Weise am Anfang der Bestromung.According to the invention, the certain period of time advantageously lies at the beginning of the current supply.

Alternativ oder zusätzlich dauert der bestimmte Zeitabschnitt nach der Erfindung vorteilhaft etwa zwischen 0,2 Sekunden und 10 Sekunden, vorzugsweise etwa zwischen 0,2 Sekunden und 5 Sekunden, weiter vorzugsweise etwa 1,5 Sekunden an. Alternatively or additionally, the specific time period according to the invention lasts advantageously between about 0.2 seconds and 10 seconds, preferably about between 0.2 seconds and 5 seconds, more preferably about 1.5 seconds.

Insbesondere bietet eine Kombination dieser beiden vorteilhaften Ausgestaltungen der Erfindung den Vorteil, dass der Türöffner auch bei einer erhöhten Vorlast sofort sicher öffnet, wonach die Vorlast nicht mehr berücksichtigt zu werden braucht und durch den Gleichstrombetrieb ein sehr ruhiger Betrieb erreicht wird.In particular, a combination of these two advantageous configurations offers the invention has the advantage that the door opener even with a increased preload immediately opens, after which the preload is no longer taken into account needs to be and by the DC operation a very quiet operation is achieved.

Die gepulste Bestromung kann jedoch erfindungsgemäß z. B. auch erst dann erfolgen, wenn die Ansteuerelektronik ein Blockieren des Türöffners festgestellt hat, wodurch erfindungsgemäß ein Gleichstrombetrieb ohne Pulsen erfolgen kann, wenn dieser zum Öffnen der Tür ausreicht.The pulsed energization can, however, according to the invention, for. B. also first then take place when the control electronics block the door opener has determined, according to the invention, a direct current operation without Pulse can occur if this is sufficient to open the door.

Es ist aber auch möglich, dass ein gepulster Betrieb immer erfolgt, jedoch nicht direkt am Anfang der Bestromung, sondern erst nachdem ein bestimmter Zeitabschnitt verstrichen ist, in dem ein Benutzer eine Tür, deren Türöffner nicht verklemmt ist, bereits passiert hätte. Auf diese Weise wird der durchschnittliche Benutzer, der keine zu frühe Vorspannung auf die Tür ausübt, nicht mit dem durch das Pulsen der Gleichspannung eventuell entstehenden kurzen Brummgeräusche belästigt, da dieses erst erfolgt. nachdem die Tür passiert wurde. Weiterhin wird aber auch dem eiligen Benutzer, der schon zu früh eine Vorspannung auf die Tür ausgeübt hat. eine erneute Anforderung einer Öffnung der Tür erspart.However, it is also possible that pulsed operation always takes place, however not directly at the beginning of the current supply, but only after a certain one Period of time has passed in which a user has a door whose Door opener is not jammed, would have already happened. That way the average user who has no early bias on the Door, not with the pulsing of the DC voltage arising short hum hum because this only occurs. after the door was passed. But also the hurried will User who has preloaded the door too early. no need to open the door again.

Erfindungsgemäß erfolgt das Pulsen der Gleichspannung vorteilhafter Weise mit einer Frequenz etwa zwischen 10 Hz und 200 Hz, vorzugsweise etwa zwischen 10 Hz und 100 Hz, weiter vorzugsweise etwa von 50 Hz oder 60 Hz. Diese Frequenzen sichern, dass der erfindungsgemäß angesteuerte Türöffner nicht verklemmt und insbesondere bietet die weiter vorzugsweise Ausführungsform den Vorteil, dass ein Benutzer kein ihm ungewohntes Brummen oder Pfeifen hört, sondern einen dem üblichen Netzbrummen entsprechenden Ton. According to the invention, the pulsing of the DC voltage takes place more advantageously Way with a frequency between about 10 Hz and 200 Hz, preferably about between 10 Hz and 100 Hz, more preferably about 50 Hz or 60 Hz. These frequencies ensure that the one controlled according to the invention Door opener is not jammed and in particular it offers the more preferred Embodiment has the advantage that a user is not unfamiliar to him Hums or whistles, but the usual Net hum corresponding sound.

Vorteilhafter Weise wird erfindungsgemäß eine zugeführte Versorgungsspannung für den Türöffner während eines bestimmten Zeitabschnittes gepulst und sonst unverändert an den Türöffner weitergeleitet, insbesondere durch die Bestromungsvorrichtung. In dieser vorteilhaften Ausgestaltung der Erfindung kann die Ansteuerelektronik nach der Erfindung einfach zwischen eine herkömmliche Stromversorgung und einen herkömmlichen Türöffner geschaltet werden und wird durch die herkömmliche Ansteuerung aktiviert, wonach die erfindungsgemäßen Vorteile ohne weiteres Dazutun erreicht werden.According to the invention, a supply voltage supplied is advantageous for the door opener during a certain period of time pulsed and otherwise passed on unchanged to the door opener, in particular through the lighting device.

In dieser Konfiguration schwingt der Oszillator bei dem Anlegen einer Versorgungsspannung an den invertierenden Schmitt-Trigger S3 mit einer durch den Widerstand R4 und den Kondensator C3 sowie die Hysterese und die Schwellenspannungen des invertierenden Schmitt-Triggers S3 bestimmten Frequenz und steuert so den MOSFET T1 so an, dass dieser den Türöffner TÖ gepulst bestromt, wenn eine positive Versorgungsspannung UBT des Türöffners angelegt ist.In this configuration, when a supply voltage is applied to the inverting Schmitt trigger S 3, the oscillator oscillates at a frequency determined by the resistor R 4 and the capacitor C 3 as well as the hysteresis and the threshold voltages of the inverting Schmitt trigger S 3 and thus controls the MOSFET T 1 so that it energizes the door opener TÖ pulsed when a positive supply voltage U BT of the door opener is applied.

Der Eingang des invertierenden Schmitt-Triggers S3 ist über eine Diode D2, deren Anode mit dem Eingang des invertierenden Schmitt-Triggers S3 verbunden ist, mit einem zweiten Zeitglied verbunden, dessen Ausgang der Ausgang eines invertierenden Schmitt-Triggers S2 ist, zwischen dessen Eingang und Masse ein Kondensator C2 geschaltet ist, aufgrund der höheren Speicherleistung vorzugsweise ein Elektrolytkondensator, und zwischen dessen Eingang und der Versorgungsspannung UBA der Ansteuerelektronik ein Widerstand R3 geschaltet ist. Das zweite Zeitglied bestimmt die Dauer der gepulsten Bestromung des Türöffners TÖ, da der Ausgang des invertierenden Schmitt-Triggers S2 den Eingang des invertierenden Schmitt-Triggers S3 auf Masse zieht, wenn der Kondensator C2 über den Widerstand R3 über die Schwelleneinschaltspannung des invertierenden Schmitt-Triggers S2 aufgeladen ist.The input of the inverting Schmitt trigger S 3 is connected via a diode D 2 , the anode of which is connected to the input of the inverting Schmitt trigger S 3 , to a second timer whose output is the output of an inverting Schmitt trigger S 2 , A capacitor C 2 is connected between its input and ground, preferably an electrolytic capacitor due to the higher storage capacity, and a resistor R 3 is connected between its input and the supply voltage U BA of the control electronics. The second timer determines the duration of the pulsed energization of the door opener TÖ, since the output of the inverting Schmitt trigger S 2 pulls the input of the inverting Schmitt trigger S 3 to ground when the capacitor C 2 via the resistor R 3 above the threshold switch-on voltage of inverting Schmitt trigger S 2 is charged.

In dieser Konfiguration ist die Dauer der gepulsten Bestromung durch den Widerstand R3 und den Kondensator C2 sowie die Schwellenspannungen des invertierenden Schmitt-Triggers S2 bestimmt.In this configuration, the duration of the pulsed energization through the resistor R 3 and the capacitor C 2 and the threshold voltages of the inverting Schmitt trigger S 2 are determined.

Der Eingang des invertierenden Schmitt-Triggers S2 ist über eine Reihenschaltung einer Diode D1 und eines Widerstandes R2, deren Anode mit dem Eingang des invertierenden Schmitt-Triggers S2 verbunden ist, mit einem ersten Zeitglied verbunden, dessen Ausgang der Ausgang eines ersten invertierenden Schmitt-Triggers S1 ist, zwischen dessen Eingang und Masse ein Widerstand R1 geschaltet ist und zwischen dessen Eingang und der Versorgungsspannung UBA der Ansteuerelektronik ein Kondensator C1 geschaltet ist. Das erste Zeitglied bestimmt den Anfang der gepulsten Bestromung des Türöffners TÖ, da der Ausgang des invertierenden Schmitt-Triggers S1 den Eingang des invertierenden Schmitt-Triggers S2 auf Masse zieht und so den Kondensator C2 entlädt bzw. entladen hält, bis der Kondensator C1 über den Widerstand R1 soweit aufgeladen ist, dass die über dem Widerstand R1 abfallende Spannung unter die Schwellenausschaltspannung des invertierenden Schmitt-Triggers S1 abgesunken ist.The input of the inverting Schmitt trigger S 2 is connected via a series circuit of a diode D 1 and a resistor R 2 , the anode of which is connected to the input of the inverting Schmitt trigger S 2 , to a first timing element, the output of which is the output of a first is inverting Schmitt trigger S 1 , between the input and ground of which a resistor R 1 is connected and between the input and the supply voltage U BA of the control electronics, a capacitor C 1 is connected. The first timer determines the start of the pulsed energization of the door opener TÖ, since the output of the inverting Schmitt trigger S 1 pulls the input of the inverting Schmitt trigger S 2 to ground and thus discharges or keeps the capacitor C 2 discharged until the capacitor is charged as far as C 1 via the resistor R 1 so that the voltage drop across the resistor R 1 voltage has fallen below the Schwellenausschaltspannung of the inverting Schmitt trigger S1.

In dieser Konfiguration ist der Anfang der gepulsten Bestromung durch den Widerstand R1 und den Kondensator C1 sowie die Schwellenspannungen des invertierenden Schmitt-Triggers S1 bestimmt.In this configuration, the beginning of the pulsed energization is determined by the resistor R 1 and the capacitor C 1 and the threshold voltages of the inverting Schmitt trigger S 1 .

In einer bevorzugten Ausführungsform ist das erste Zeitglied so eingestellt, dass der Kondensator C2 des zweiten Zeitgliedes möglichst schnell entladen und direkt danach zum Aufladen über den Widerstand R3 freigegeben wird, wodurch ein gepulster Betrieb des Türöffners TÖ am Anfang des Betriebes des Türöffners TÖ mit einer nachfolgenden Dauerbestromung erfolgt.In a preferred embodiment, the first timing element is set such that the capacitor C 2 of the second timing element is discharged as quickly as possible and released immediately afterwards for charging via the resistor R 3 , as a result of which pulsed operation of the door opener TÖ at the beginning of the operation of the door opener TÖ a subsequent permanent current supply.

Die Versorgungsspannung UBA der Ansteuerelektronik wird z. B. von einem Spannungsregeler erzeugt, der aus einer zwischen der Versorgungsspannung UBT des Türöffners TÖ und Masse geschalteten Reihenschaltung eines Widerstandes R6 und einer Zenerdiode ZD1, wobei die Anode der Zenerdiode ZD1 an Masse liegt, einem NPN-Transistor T2, dessen Kollektor an der Versorgungsspannung UBT des Türöffners TÖ liegt und dessen Basis an dem Verbindungspunkt des Widerstandes R6 und der Zenerdiode ZD1 liegt, und einem Widerstand R7 besteht. der zwischen den Emitter des NPN-Transistors T2 und Masse geschaltet ist. Die Versorgungsspannung UBT der Ansteuerelektronik liegt in diesem Fall an dem Emitter des NPN-Transistors T2 an. Der Spannungsregeler kann als zu der Ansteuerelektronik zugehörig betrachtet werden.The supply voltage U BA of the control electronics is, for. B. generated by a voltage regulator, which consists of a series connection of a resistor R 6 and a Zener diode ZD 1 connected between the supply voltage U BT of the door opener TÖ and ground, the anode of the Zener diode ZD1 being connected to ground, an NPN transistor T 2 , the Collector is at the supply voltage U BT of the door opener TÖ and whose base is at the connection point of the resistor R 6 and the Zener diode ZD 1 , and there is a resistor R 7 . which is connected between the emitter of the NPN transistor T 2 and ground. In this case, the supply voltage U BT of the control electronics is present at the emitter of the NPN transistor T 2 . The voltage regulator can be regarded as belonging to the control electronics.

Liegt also die Versorgungsspannung UBT des Türöffners TÖ an der erfindungsgemäßen Ansteuerelektronik an, so erfolgt automatisch die erfindungsgemäße Bestromung des Türöffners TÖ über den Schalttransistor, hier den MOSFET T1.If the supply voltage U BT of the door opener TÖ is present at the control electronics according to the invention, then the door opener TÖ is automatically energized via the switching transistor, here the MOSFET T 1 .

Die Figur 3 zeigt im oberen Teil einen beispielhaften Verlauf einer Eingangsspannung der Ansteuerelektronik, hier die Versorgungsspannung UBT des Türöffners TÖ, und im unteren Teil den Verlauf der korrespondierenden Ausgangsspannung der Ansteuerelektronik, d. h. der am Türöffner TÖ tatsächlich anliegenden Spannung, mit einem gepulsten Betrieb am Anfang.3 shows in the upper part an example of a profile of an input voltage of the control electronics, here the supply voltage U BT of the door opener TÖ, and in the bottom part the profile of the corresponding output voltage of the control electronics, i.e. the voltage actually applied to the door opener TÖ, with a pulsed operation on Beginning.

Die erfindungsgemäße Ansteuerelektronik ist vom Bauraumbedarf klein gehalten und kann mit einem Netzteil zusammengefasst sein. Vorteilhafter Weise wird die Eingangs- und Ausgangsspannung durch aufsteckbare Anschlussklemmen an eine die Ansteuerelektronik enthaltende Platine angelegt, die bevorzugt verpolungssicher ausgelegt sind.
