Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Überwachung des Stromkreises einer Schutzeinrichtung an durch einen Antrieb bewegbaren Schließkanten von insbesondere auto matisch betätigbaren miteinander zusammenwirkenden Türen, wobei in den Schließkanten als Druckleisten ausgebildete Elektroden angeordnet sind, die mit einer Versorgungsspan nung versehen am Ende elektrisch miteinander verbunden sind.The invention relates to a device for monitoring of the circuit of a protective device by a Drive movable closing edges in particular auto interlocking doors that can be actuated mechanically, being formed in the closing edges as pressure strips Electrodes are arranged with a supply chip provided electrically connected at the end are.
Die gattunggemäße Schutzeinrichtung ist in der US- PS 37 54 176 und eine spezielle Ausführung und Verbes serung dieser Einrichtung in dem deutschen Patent 27 19 438 näher beschrieben.The generic protective device is in the US PS 37 54 176 and a special version and verb This device is included in the German patent 27 19 438 described in more detail.
Eine derartige Schutzeinrichtung weist an einer durch einen Antrieb bewegbaren Schließkante wenigstens zwei sich über die Länge der Schließkante erstreckende und im Abstand voneinander angeordnet eine Schaltleiste bil dende Elektroden auf.Such a protective device has one a drive movable closing edge at least two extending over the length of the closing edge and in At a distance from each other a safety edge bil electrodes.
Die Elektroden können gegen elastische Kräfte einander genähert und in Berührung gebracht werden sowie mit ihren Enden an eine Spannungsquelle und an ein Steuergerät ange schlossen und derart verbunden werden, daß bei Nichtberüh ren der Elektroden ein Ruhestrom fließt. Das entsprechende Steuergerät löst sowohl beim Anstoßen eines Hindernisses an die Schließkanten als auch bei einer Unterbrechung der Elektroden ein Steuersignal zum Anhalten oder Reversieren des Antriebes aus, wobei die Elektroden an ihrem einen Ende durch einen Meßwiderstand überbrückt sind und das Steuergerät mit der Spannungsquelle an das andere Ende der Elektroden angelegt ist.The electrodes can counter each other against elastic forces to be approached and brought into contact with her Ends to a voltage source and to a control unit closed and connected in such a way that when not in contact a quiescent current flows. The corresponding Control unit triggers both when hitting an obstacle to the closing edges as well as when the Electrodes a control signal for stopping or reversing of the drive, with the electrodes on their one Are bridged by a measuring resistor and that Control unit with the voltage source at the other end of the Electrodes is applied.
Die praktische Funktion einer derartigen Schutzeinrichtung wird in nachteiliger Weise dann in Frage gestellt, wenn die in der Anwendung verhältnismäßig langen Anschluß leitungen zwischen Steuergerät und Elektroden, durch Ver schleiß und Bruch bedingt, Kriechströme oder Nebenströme zulassen, die einen Widerstand bilden. Ein solch geschlos sener Kreis simuliert unter falschen Bedingungen die Funk tionsfähigkeit der Schutzüberwachungseinrichtung und das Steuergerät reagiert nicht auf fälschlich auftretende Be rührungen oder Kontakte der sogenannten Schaltleisten.The practical function of such a protective device is adversely questioned if the connection which is relatively long in use cables between control unit and electrodes, by Ver wear and breakage, leakage currents or secondary currents allow that form a resistance. Such a closed Its circuit simulates radio under the wrong conditions ability of the protective monitoring device and Control unit does not respond to incorrectly occurring loads Stirrings or contacts of the so-called safety edges.
Demgegenüber liegt der Erfindung die Aufgabe zu grunde, eine Überwachungseinrichtung zu schaffen, die die oben ge nannten Fehler ausschließt und die in zuverlässiger Weise eine ständige Selbstüberwachung der Schutzeinrichtung ge währleistet. In contrast, the invention is based on the object to create a monitoring device that the above ge excludes named errors and that in a reliable manner constant self-monitoring of the protective device ensures.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Druckleisten beidseitig über einen aktiven Abschluß in Form eines Frequenzgenerators, miteinander verbunden sind, und daß zur Überwachung der Frequenz eine Auswerteeinheit vorgesehen ist.This object is achieved in that the Print strips on both sides via an active termination in Form of a frequency generator, are interconnected, and that for monitoring the frequency an evaluation unit is provided.
Der als aktiver Abschluß zu bezeichnende Frequenzgenerator bringt eine ständige Frequenz als Ausgangssignal für die Überwachung. Diese Frequenz ist der Versorgungsspannung überlagert und kann in Grenzen nach oben und unten ständig überprüft werden, so daß ein selektives Erkennen möglich ist. Ein Kriech- oder Nebenstrom würde die Frequenz er kennbar ändern oder sogar ausfallen lassen. In jedem Fall ist eine ständige Überwachung der Schutzeinrichtung vor handen.The frequency generator to be called an active termination brings a constant frequency as an output signal for the Monitoring. This frequency is the supply voltage overlays and can move up and down within limits be checked so that selective recognition is possible is. A leakage or bypass would increase the frequency noticeably change or even drop out. In any case is a constant monitoring of the protective device act.
Der aktive Abschluß wird innerhalb der Auswerteeinheit über eine Konstantspannungsversorgung und eine Entkopplung mit einer aufbereiteten Spannung über die Druckleisten versorgt. Der benötigte Strom wird im Rhythmus der Fre quenz über eine innerhalb der Auswerteeinheit angeordnete Frequenzauswertung überwacht. Bei Berühren oder Kontakt der Druckleisten kommt es zu einer Frequenzänderung, die über den, der Frequenzauswertung nachgeschalteten Mono- Flopp erkennbar ist. Ein entsprechendes Steuerrelais bzw. Leistungstreiber beaufschlagt die Motorsteuerung. Inner halb der Auswerteeinheit ist zusätzlich eine Leitungsüber wachung mit einem Leuchtmelder, in Form einer Lampe, ange ordnet. Diese Leitungsüberwachung wirkt zusätzlich auf das Steuerrelais bzw. auf den Leistungstreiber. The active completion is within the evaluation unit via a constant voltage supply and decoupling with a prepared tension across the pressure bars provided. The electricity required is in the rhythm of Fre sequence via an arranged within the evaluation unit Frequency evaluation monitored. When touched or in contact the pressure bars there is a frequency change that via the mono downstream of the frequency evaluation Flopp is recognizable. A corresponding control relay or Power driver acts on the engine control. Inner There is also a line over the evaluation unit monitoring with an indicator light, in the form of a lamp arranges. This line monitoring also affects the Control relay or on the power driver.
Vorteilhafterweise erfolgt die Frequenzauswertung über eine Elektronik, die das Signal für ein nachtriggerbares Mono-Flopp aufbereitet. Das bereits erwähnte Mono-Flopp benötigt einen gleichmäßigen Impuls. Bei Änderung oder Ausbleiben des Impulses reagiert das Mono-Flopp.The frequency evaluation is advantageously carried out via electronics that provide the signal for a retriggerable Processed mono flop. The aforementioned mono flop needs a steady impulse. In case of change or The mono-flop reacts when there is no pulse.
Ein Ausführungsbeispiel der Erfindung ist anhand eines Blockschaltbildes in der Zeichnung dargestellt und wird im Nachfolgenden näher erläutert.An embodiment of the invention is based on a Block diagram shown in the drawing and is in The following explains in more detail.

Leistungstreiber zum Ansteuern der nicht dargestellten Motorsteuerung. Zusätz lich befindet sich in der Auswerteeinheit 5 eine Leitungs überwachung 8, die mit einem Leuchtmelder 12 gekoppelt ist und zusätzlich über das Steuerrelais 11 bzw. Leistungs treiber auf die nicht dargestellte Motorsteuerung wirkt.The usual and required supply voltage 4 is supplied from a supply source, not shown, to the evaluation unit 5 .
