Three of these (31) are individually connected to sensors, such as a proximity switch (26), and an opto-electronic detector (27) and limit switch (28) which monitor door position, etc. The other microprocessor monitors the function of the other three and, in the event of a fault, initiates an emergency action for the motor.

Description

Die Erfindung betrifft eine Steuerungseinrichtung für einen motorischen Antrieb einer Tür- oder Fensteranlage mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a control device for a motor drive a door or window system with the features of the preamble of the claim 1.

Die DE 43 02 035 A1 zeigt eine Steuerungseinrichtung für einen motorischen Antrieb einer Tür- oder Fensteranlage mit mindestens einem angetriebenen Flügel. Die Steuerungseinrichtung weist einen Rechner mit Speicher und eine Sicherungseinrichtung auf, wobei die Steuerungseinrichtung mit einem ersten und einem zweiten Mikroprozessor ausgestattet ist, die miteinander kommunizieren können. Die Signale von Sensoren und Schaltem werden jeweils beiden Mikroprozessoren zugeleitet, so dass eine doppelte Überwachung dieser Sensoren und Schalter erfolgt. Diese Anordnung ist in der Verdrahtung relativ aufinrändig und bedarf außerdem der Verwendung zweier geeigneter Mikroprozessoren, d.h. jeweils mit einer ausreichenden Anzahl von Eingängen für alle Eingangsinformationen. Eine Nachrüstbarkeit einer bestehenden Steuerungseinrichtung mit einem Mikroprozessor auf eine doppelte Überwachung der Sensoren und Schalter ist somit praktisch unmöglich.DE 43 02 035 A1 shows a control device for a motor drive a door or window system with at least one driven leaf. The control device has a computer with memory and a safety device on, wherein the control device with a first and a second microprocessor is equipped to communicate with each other can. The signals from sensors and switches are both microprocessors fed so that double monitoring of these sensors and Switch is done. This arrangement is relatively arduous in wiring and also requires the use of two suitable microprocessors, i.e. each with a sufficient number of inputs for all input information. A retrofit of an existing control device with a Microprocessor for double monitoring of sensors and switches therefore practically impossible.

Die DE 39 40 762 A1 beschreibt eine Vorrichtung zur elektronischen Steuerung einer automatischen Schiebetür, die mit einer selbstüberwachenden elektronischen Zusatzsteuerung versehen ist, die als separater Sicherheitsbaustein ausgeführt ist. Der Sicherheitsbaustein überwacht die Öffnungsbewegung der Schiebetür und testet das Arbeiten des Antriebsmotors. Bei Rettungs- und Fluchttüren aktiviert der Sicherheitsbaustein bei Funktionsstörungen eine Notlauffunktion, um die Tür zu öffnen. Bei dieser Anordnung unterbleibt eine Überwachung der elektronischen Steuerung an sich, so dass gegebenenfalls hier auftretende Fehler unerkannt bleiben könnten.DE 39 40 762 A1 describes a device for electronic control an automatic sliding door with a self-monitoring electronic Additional control is provided, which is designed as a separate safety module is. The safety module monitors the opening movement of the sliding door and tests the working of the drive motor. With rescue and escape doors the safety module activates an emergency function in the event of malfunctions to open the door. With this arrangement, the electronic is not monitored Control itself, so that any errors that occur here are not recognized could stay.

Der Erfindung liegt die Aufgabe zugrunde, eine Steuerungseinrichtung einer automatischen Türanlage zu entwickeln, die die Sicherheit der Anlage erhöht.

Der zweite Mikroprozessor dient ohne eine parallele Verarbeitung der Eingangsinformationen ausschließlich der Überwachung des mindestens einen ersten Mikroprozessors. Hierdurch ist die Steuerungseinrichtung in ihrem Aufbau unkompliziert. Außerdem besteht mit der erfindungsgemäßen Anordnung die Möglichkeit, bestehende Anlagen mit einer Steuerungseinrichtung mit mindestens einem Mikroprozessor, mit einer Sicherungseinrichtung, umfassend einen weiteren Mikroprozessor, nachzurüsten, indem der weitere Mikroprozessor an die bei Mikroprozessoren übliche Schnittstelle des anderen Mikroprozessors angeschlossen wird. Bestehende Anlage lassen sich so leicht auf eine zeitgemäßen Sicherheitsstandard bringen.The second microprocessor serves without parallel processing of the input information exclusively monitoring the at least one first microprocessor. As a result, the structure of the control device is uncomplicated. In addition, with the arrangement according to the invention, there is the possibility of existing systems with a control device with at least one microprocessor, with a safety device, comprising a further microprocessor, retrofit by adding the additional microprocessor to that of microprocessors usual interface of the other microprocessor is connected.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel handelt es sich um eine automatische Schiebetüranlage. Sie weist zwei Schiebetürflügel 1, 2 auf, die motorisch gegenläufig angetrieben sind. Die Schiebetürflügel 1, 2 sind über Roflenwagen 3 in einer horizontalen ortsfesten Laufschiene 4 verschiebbar geführt. The exemplary embodiment shown in FIG. 1 is an automatic one Sliding door system. It has two sliding door leaves 1, 2, the motor are driven in opposite directions. The sliding door leaves 1, 2 are via Roflen wagons 3 slidably guided in a horizontal stationary track 4.

Der Antrieb weist einen Elektromotor 5 auf, der mit einer elektronischen Steuereinrichtung 10 verbunden ist. Der Motor 5 treibt einen Zahnriemen 15 an, der über an der Laufschiene ortsfest gelagerte Umlenkrollen 15a, 15b umlaufend geführt ist und mit den Schiebetürflügeln 1, 2 gekoppelt ist.The drive has an electric motor 5, which is equipped with an electronic control device 10 is connected. The motor 5 drives a toothed belt 15 which is about deflection rollers 15a, 15b, which are mounted in a stationary manner on the running rail, are guided circumferentially and is coupled to the sliding door leaves 1, 2.

Hierzu ist das untere Trum des Zahnriemens 15 über einen Mitnehmer 1a mit dem Schiebeflügel 1 verbunden und das obere Trum über einen Mitnehmer 2a mit dem Schiebeflügel 2, so daß sich die Flügel 1, 2 nur in jeweils entgegengesetzten Richtungen bewegen können.For this purpose, the lower run of the toothed belt 15 via a driver 1a with the Sliding sash 1 connected and the upper run via a driver 2a with the Sliding wing 2, so that the wings 1, 2 only in opposite each other Can move directions.

Die Ansteuerung des Motors 5 erfolgt über ein mit einem elektronischen Rechner und Speicher ausgestattetes Steuer- und Regelgerät 10, das beispielsweise an der Laufschiene ortsfest gelagert ist. Durch einen nicht dargestellten externen Schalter oder einen Ansteuerungssensor werden die Schiebeflügel 1, 2 aus der in Fig. 1 dargestellten Schließlage über den Motor geöffnet und später wieder automatisch gesteuert über den Motor geschlossen.The motor 5 is controlled by means of an electronic computer and memory equipped control and regulation device 10, for example the running track is fixed in place. By an external, not shown Switch or a control sensor, the sliding sash 1, 2 from the in Fig. 1 shown closed position on the motor and later automatically again controlled closed by the motor.

Figur 2 zeigt in symbolischer Darstellung die Funktionsweise einer herkömmlichen automatischen Türanlage mit Überwachung der Steuerungseinheit 10 durch den separaten Sicherheitsbaustein 25. Der in der Steuerungseinheit enthaltene Mikroprozessor 31 erhält alle Eingangssignale, z.B. Signale aus einem Näherungsmelder 26, einer Lichtschranke 27 oder einem Endschalter 28.Figure 2 shows a symbolic representation of the operation of a conventional automatic door system with monitoring of the control unit 10 by the separate security module 25. The microprocessor contained in the control unit 31 receives all input signals, e.g. Signals from a proximity sensor 26, a light barrier 27 or a limit switch 28.

Die Signalverarbeitung erfolgt nacheinander Der Sicherheitsbaustein erhält die gleichen Eingangssignale wie die Steuerungseinheit. Steuerungseinheit und Sicherungsbaustein kommunizieren miteinander, so daß der Sicherungsbaustein eine Funktionsstörung der Steuerungseinheit erkennen kann und gegebenenfalls über den Relaisschalter 29 einen Notlauf des Motors 5 aktiviert.The signals are processed one after the other. The safety module receives the same input signals as the control unit. Control unit and fuse module communicate with each other so that the fuse block can detect a malfunction of the control unit and, if necessary An emergency operation of the motor 5 is activated via the relay switch 29.

Figur 3 zeigt eine erste Ausführung der Steuerungseinheit 10, die mehrere Mikroprozessoren 31, 32 enthält. Jeder der Mikroprozessoren 31 ist für die Signalverarbeitung nur eines der Eingangssignale - es handelt sich dabei z. B. um die o. g. Eingangssignale 26, 27 oder 28 - zuständig. Hierdurch ist eine echte parallele Signalverarbeitung (Multiprocessing) möglich, die effektiver und schneller als die herkömmliche Verarbeitungsweise ist. Der Mikroprozessor 32 kommuniziert mit den Mikroprozessoren 31 und kann so deren Funktion überwachen. Bei Funktionsstörungen kann der Mikroprozessor 31 gegebenenfalls über einen Schalter den Motor 5 zu einem Notlauf aktivieren. Ein Netzteil 33 ist vorgesehen. Die Sicherheitsfunktion übernehmen alle Mikroprozessoren gemeinsam, indem sie sich gegenseitig überwachen. Im Fehlerfall wird zuerst ein Notbetrieb aktiviert und falls dieser fehlschlägt, die Versorgungsspannung der gesamten Anlage abgeschaltet, so daß die für diesen Fall vorhandenen Sicherheitseinrichtungen zum Tragen kommen.Figure 3 shows a first embodiment of the control unit 10, the multiple microprocessors 31, 32 contains. Each of the microprocessors 31 is for signal processing only one of the input signals - it is e.g. B. the above Input signals 26, 27 or 28 - responsible. This is a real parallel Signal processing (multiprocessing) possible, which is more effective and faster than that is conventional processing. The microprocessor 32 communicates with the microprocessors 31 and can thus monitor their function. In the event of malfunctions the microprocessor 31 can optionally via a switch activate engine 5 for emergency operation. A power supply 33 is provided. The safety function take over all microprocessors together by themselves monitor each other. In the event of a fault, emergency operation is activated first and if this fails, the supply voltage of the entire system is switched off, so that the safety devices available for this case come into play come.

In Figur 4 ist eine zweite Ausführung der Steuerungseinheit 10 dargestellt, die mehrere Mikroprozessoren 31, 32 enthält. Die Steuerungseinheit 10 weist zwei Mikroprozessoren 31, 32 auf, welche beispielsweise über ein Bussystem miteinander verbunden sind. Im Unterschied zur vorhergehenden Ausführung werden alle oder fast alle Eingangssignale, z. B. die o. g. Eingangssignale 26, 27, 28, direkt dem ersten Mikroprozessor 31 zugeführt und dort verarbeitet. Der erste Mikroprozessor 31 steuert zudem den Motor 5. Der zweite Mikroprozessor 32 dient bei dem Ausführungsbeispiel ausschließlich der Überwachung des ersten Mikroprozessors 31, jedoch ohne eine parallele Verarbeitung der Eingangsinformationen. Es werden Mitteilungen über den jeweiligen Betriebsstatus zwischen beiden Einheiten 31, 32 ausgetauscht und über die Softwarefunktion eine gegenseitige Ablaufüberwachung durchgeführt. Insbesondere meldet der erste Mikroprozessor 31 jede Änderung seines Betriebsstatus an den zweiten Mikroprozessor 32, welcher eine Plausibilitätsprüfung anhand der dem Betrieb der Automatikschiebetür 1 zu Grunde liegenden Ablaufprogramme durchführt. Unter anderem wird dabei berücksichtigt, welche Betriebsstati zugelassen sind und wie deren Verkettung und zeitliche Abfolge beschaffen ist. Wird vom zweiten Mikroprozessor 32 eine Fehlfunktion des ersten Mikroprozessors 31 erkannt, so wird ein Fehlersignal generiert und einer in der Steuereinheit 10 vorhandenen Logikschaltung 34, welche im einfachsten Fall aus einem ODER-Gatter besteht, zugeführt. Der zweite Mikroprozessor 32 wird entsprechend in seiner Funktion durch den ersten Mikroprozessor 31 überwacht. Auch hier wird bei Erkennung einer Fehlfunktion oder eines Ausfalls ein Fehlersignal der Logikschaltung 34 zugeführt. Bei Vorliegen eines Fehlersignals von wenigstens einem der beiden Mikroprozessoren 31, 32 steuert die Logikschaltung 34 ein Relais 35 an, welches die Steuereinheit 10 komplett abschaltet, indem ein Schalter 35a in der Zuleitung vom Netzteil 33 zu der Steuereinheit 10 geöffnet wird. Alternativ kann bei einer Fehlfunktion des zweiten Mikroprozessors 32 dieser separat abgeschaltet werden und die Steuerungseinheit 10 allein mit dem ersten Mikroprozessor weiterbetrieben werden.FIG. 4 shows a second embodiment of the control unit 10, which contains a plurality of microprocessors 31, 32. The control unit 10 has two Microprocessors 31, 32, which are connected to one another, for example, via a bus system are connected. In contrast to the previous version all or almost all input signals, e.g. B. the above Input signals 26, 27, 28, fed directly to the first microprocessor 31 and processed there. The first Microprocessor 31 also controls motor 5. Second microprocessor 32 only serves to monitor the first in the exemplary embodiment Microprocessor 31, but without parallel processing of the input information. There are messages about the respective operating status between exchanged two units 31, 32 and a mutual via the software function Process monitoring carried out. In particular, the first microprocessor reports 31 any change in its operating status to the second microprocessor 32, which is a plausibility check based on the operation of the automatic sliding door 1 executes the underlying sequence programs. Amongst other things it is taken into account which operating statuses are permitted and how Chaining and chronological order is obtained. Is from the second microprocessor If a malfunction of the first microprocessor 31 is detected, an error signal is generated generated and a logic circuit 34 present in the control unit 10, which in the simplest case consists of an OR gate. The second Microprocessor 32 is accordingly in its function by the first microprocessor 31 monitors. Again, if a malfunction is detected or an error signal of the logic circuit 34 is supplied. If available an error signal from at least one of the two microprocessors 31, 32 controls the logic circuit 34 a relay 35 which the control unit 10 switches off completely by a switch 35a in the feed line from the power supply 33 the control unit 10 is opened. Alternatively, if the second microprocessor 32 this can be switched off separately and the control unit 10 can only be operated with the first microprocessor.

Um bestehende Anlage nachzurüsten ist es auch möglich den zweiten Mikroprozessor 32 und die Logikschaltung 34 über eine vorhandene Schnittstelle mit dem ersten Mikroprozessor 31 zu verbinden.To retrofit existing systems, it is also possible to use the second microprocessor 32 and the logic circuit 34 via an existing interface with the to connect the first microprocessor 31.

Bei den Ausführungsbeispielen der Figuren 3 und 4 ergibt sich aufgrund der kommunizierenden Mikroprozessoren eine in die Steuerungseinrichtung integrierte Sicherheitseinrichtung.In the exemplary embodiments of FIGS. 3 and 4, the result is that of communicating Microprocessors an integrated in the control device Safety device.
