Description

Die Erfindung betrifft einen Torantrieb, insbesondere für Industrietore, Garagentore und/oder Tore für Einfriedungen, mit einem Antriebsaggregat zum Öffnen und/oder Schließen des Tores, einer Steuereinrichtung zum Steuern des Antriebsaggregats und einer der Steuereinrichtung zugeordnete Zutrittskontrolleinrichtung zum Durchführen einer Identifikation einer Einlaß begehrenden Person oder eines Einlaß begehrenden Fahrzeugs und zum automatischen Einleiten einer Toröffnungsbewegung, wenn die Identifikation die Person bzw. das Fahrzeug als berechtigt ausweist, wobei die Zutrittskontrolleinrichtung eine dem Motorantriebsaggregat zugeordnete stationäre Einheit und eine der Person oder dem Fahrzeug zugeordnete mobile Einheit umfaßt und die Personen- bzw. Fahrzeugidentifikation über Senden und Empfangen von codierten Signalen zwischen diesen Einheiten erfolgt.The invention relates to a door operator, in particular for industrial gates, Garage doors and / or gates for fencing, with a drive unit to open and / or close the gate, a control device for Control of the drive unit and one assigned to the control device Access control device for performing identification of an inlet desiring person or a vehicle desiring admission and to automatic initiation of a gate opening movement when the identification identifies the person or vehicle as authorized, the Access control device assigned to the motor drive unit stationary unit and one assigned to the person or the vehicle includes mobile unit and the person or vehicle identification via Sending and receiving coded signals between these units he follows.

Solche Torantriebe sind im Stand der Technik weit verbreitet. Um eine bequeme Ansteuerung des Torantriebs z.B. vom Fahrerplatz eines Fahrzeugs aus durchführen zu können, weisen nahezu alle derzeit auf dem Markt befindliche Torantriebe die Möglichkeit einer Funkfernbedienung auf. Dabei ist dem Fahrzeug eine mobile Einheit in Form eines Handfunksenders oder eines in oder an dem Fahrzeug installierten Senders zugeordnet. Wird eine Taste an diesem Sender gedrückt, so sendet er ein codiertes Signal aus, das von einer dem Torantrieb zugeordneten stationären Einheit in Form eines Funkempfängers empfangen wird. Paßt der Code des gesendeten Signals mit einem in dem Empfänger gespeicherten Code zusammen, so wird automatisch die Toröffnungsbewegung eingeleitet. Durch Drücken einer Taste eines berechtigten Senders wird somit der Fahrer oder sein Fahrzeug als berechtigt identifiziert. Diese Art und Weise der Torantriebssteuerung ist bereits sehr komfortabel. Jedoch muß der Fahrer bisher zur Torantriebssteuerung die Taste am Sender drücken, weshalb er seine Hand vom Lenkrad nehmen muß und kurzzeitig vom Verkehrsgeschehen abgelenkt ist. Dies kann unter Umständen bei Toreinfahrten, wozu man sich eventuell einordnen muß und den Blinker betätigen muß und auf entgegenkommenden und nachfolgenden Verkehr achten muß, zu gefährlichen Situationen führen.Such gate drives are widely used in the prior art. To one convenient control of the door operator e.g. from the driver's seat of a vehicle almost all of them are currently on the market door drives located on the possibility of a radio remote control. It is the vehicle has a mobile unit in the form of a handheld radio transmitter or assigned in or installed on the vehicle transmitter. Will a key on pressed on this transmitter, it sends out a coded signal from a the stationary unit assigned to the door drive in the form of a Radio receiver is received. Does the code of the transmitted signal match? a code stored in the receiver the door opening movement is automatically initiated. By pressing a button of an authorized transmitter, the driver or his vehicle is thus legitimately identified. This way the door operator control is already very comfortable. However, the driver has to date Door operator control press the button on the transmitter, which is why he put his hand must take off the steering wheel and briefly distracted from the traffic is. Under certain circumstances, this may be the case when entering gates, which you may consider must classify and operate the turn signal and on oncoming and following traffic must lead to dangerous situations.

Es ist daher Aufgabe der Erfindung, einen Torantrieb der eingangs genannten Art derart weiterzubilden, daß er bei äußerst komfortabler Bedienung solche gefährlichen Situationen vermeiden hilft.It is therefore an object of the invention to provide a door drive of the type mentioned Art to develop in such a way that it is extremely comfortable to use avoid dangerous situations.

Dies wird erfindungsgemäß dadurch gelöst, daß die Zutrittskontrolleinrichtung eine Näherungserfassungseinrichtung zum automatischen Erfassen eines Annäherns einer Person oder eines Fahrzeugs aufweist und derart ausgebildet ist, daß sie bei Erfassen eines solchen Annäherns automatisch die Identifikation durchführt, wodurch bei Annähern einer Person oder eines Fahrzeugs, der bzw. dem die mobile Einheit zugeordnet ist, automatisch eine Toröffnung erfolgt.This is achieved according to the invention in that the access control device a proximity detection device for automatically detecting a Has approaching a person or a vehicle and such is designed so that it automatically detects such an approach carries out the identification, whereby when a person or person approaches Vehicle to which the mobile unit is assigned automatically one The gate is opened.

Durch diese Maßnahmen ist ein vollautomatischer Torantrieb geschaffen, bei dem ein eine Toreinfahrt begehrender Fahrer zum Ansteuern überhaupt nicht mehr tätig werden muß. Durch die Näherungserfassungseinrichtung wird also sein Annähern bzw. das seines Fahrzeugs automatisch erfaßt. Dennoch ist der Torantrieb gegen unbefugten Zutritt gesichert, denn die Torantriebssteuerung erfolgt erst, nachdem eine Identifizierung über Senden und Empfangen von Codesignalen durchgeführt worden ist. Diese Personenidentifikation bzw. Fahrzeugidentifikation wird bei durch die Näherungserfassungseinrichtung erfaßtem Annähern vollkommen automatisch durchgeführt.These measures create a fully automatic door operator, at a driver who desires to enter the gate does not want to go at all must do more. By means of the proximity detection device his approaching or that of his vehicle is automatically detected. Still is the door drive is secured against unauthorized access, because the door drive control only takes place after identification via send and Receiving code signals has been performed. This Personal identification or vehicle identification is carried out by the Proximity detection device detects approaching completely automatically carried out.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Subclaims.

So kann die Näherungserfassungseinrichtung in Form eines die Toreinfahrt überwachenden Bewegungssensors vorliegen. Ein solcher Bewegungssensor könnte z. B. derart ausgelegt sein, daß er nicht irgendeiner Bewegung eines z.B. wärmeausstrahlenden Gegenstands bzw. einer wärmeaustrahlenden Person erfaßt, sondern tatsächlich nur dann ein Annäherungssignal abgibt, wenn sich der Gegenstand bzw. die Person in Richtung auf das Tor zu bewegt. Die gleiche Funktion können auch eine oder mehrere Lichtschranken, oder eine oder mehrere Kontaktschwellen, Kontaktmatten oder dergleichen im Toreinfahrtsbereich am Boden befindliche Kontakteinrichtungen erfüllen. Die Näherungserfassungseinrichtung kann mit einem oder auch mit mehreren solcher Näherungssensoren versehen sein. Bei einer alternativen vorteilhaften Ausgestaltung kommt die Näherungserfassungs-einrichtung auch ohne solche separat anzubringenden Näherungssensoren aus. Dabei ist vorgesehen, daß die Näherungserfassungseinrichtung mit der mobilen und/oder stationären Einheit verbunden ist und wenigstens eine der beiden Einheiten zum ständigen oder in bestimmten Abständen erfolgenden Senden eines Meßsignals veranlaßt, wobei die andere Einheit zum Empfangen und Erkennen des Meßsignals ausgebildet ist und eine Signalauswerteeinrichtung aufweist, die anhand des empfangenen Meßsignals oder anhand eines in zeitlichen Abständen erfolgenden mehrfachen Empfangs des Meßsignals - insbesondere anhand der Signalstärke und/oder anhand von Dopplereffekten - ein relatives Annähern der das Meßsignal sendenden Einheit erfaßt. Die stationäre Einheit ist bevorzugt ein Funkempfänger oder Funksendeempfänger. Die mobile Einheit umfaßt vorzugsweise einen Handfunksender, eine Funkfernbedienung oder einen mobilen Funksendeempfänger. So the proximity detection device in the form of a gate entrance monitoring motion sensor. Such a motion sensor could e.g. B. be designed so that it does not cause any movement e.g. heat radiating object or a heat radiating Person is detected, but actually only emits an approach signal, if the object or person is towards the gate emotional. One or more light barriers, or one or more contact thresholds, contact mats or the like in Contact devices located on the floor meet the gate entrance area. The Proximity detection device can have one or more such proximity sensors. In an alternative advantageous The proximity detection device also comes without one proximity sensors to be attached separately. It is provided that the proximity detection device with the mobile and / or stationary Unit is connected and at least one of the two units for constant or at certain intervals sending a Measurement signal causes, the other unit for receiving and Detection of the measurement signal is formed and a signal evaluation device has, which on the basis of the received measurement signal or on the basis of a time intervals of multiple reception of the measurement signal - especially based on the signal strength and / or based on Doppler effects - a relative approach of the unit sending the measurement signal is detected. The stationary unit is preferably a radio receiver or radio transceiver. The mobile unit preferably comprises a hand-held radio transmitter, a radio remote control or a mobile radio transceiver.

Die Funktion des in Figur 1 stilisiert dargestellten Torantriebs 10 in der ersten Ausführungsform wird im folgenden näher erläutert. Der stationäre Sendeempfänger sendet in bestimmten Abständen, z.B. alle 15 Sekunden, ein Meßsignal 26 aus. Dieses Meßsignal 26 wird von dem sich mit dem Fahrzeug 20 nähernden mobilen Sendeempfänger 24 empfangen. Der mobile Sendeempfänger 24 umfaßt eine Signalauswerteschaltung (A), die Teil einer Näherungserfassungseinrichtung 28 ist. Die Signalauswerteschaltung (A) vergleicht die Feldstärke mehrerer nacheinander empfangener Meßsignale 26 und gibt, wenn sich die Feldstärke erhöht, ein Näherungssignal an den mobilen Sendeempfänger 24 aus. Der mobile Sendeempfänger 24 sendet daraufhin ein Codesignal 30, das der stationäre Sendeempfänger 22 empfängt. Bei passendem Code des Codesignals 30 wird daraufhin durch die Steuerschaltung 16 der Motor 14 zum Öffnen des Tores 12 angesteuert. Vielfältige Abwandlungen dieser Ausführungsform sind möglich, die alle das Grundprinzip enthalten, anhand von gesendeten und empfangenen Signalen - die gleichzeitig auch als Codesignale zum Öffnen des Tores verwendbar sind - eine Relativbewegung zwischen jeweiligem Sender und Empfänger 22, 24, nämlich ein Annähern derselben, festzustellen, verwirklichen. Dies wäre auch z.B. über das Feststellen von Frequenzverschiebungen (Dopplereffekt) denkbar.The function of the door drive 10 shown stylized in FIG. 1 in the first Embodiment is explained in more detail below. The stationary Transceiver transmits at certain intervals, e.g. every 15 seconds, on Measurement signal 26 off. This measurement signal 26 is different from that with the vehicle 20 approaching mobile transceiver 24 received. The mobile Transceiver 24 comprises a signal evaluation circuit (A) which is part of a Proximity detector 28 is. The signal evaluation circuit (A) compares the field strength of several successively received measurement signals 26 and, when the field strength increases, gives a proximity signal to the mobile transceiver 24 from. The mobile transceiver 24 is transmitting thereupon a code signal 30 which the stationary transceiver 22nd receives. If the code of the code signal 30 is suitable, the Control circuit 16 of the motor 14 controlled to open the gate 12. Various modifications of this embodiment are possible, all of which Basic principle included, based on sent and received signals - Which can also be used as code signals to open the gate a relative movement between the respective transmitter and receiver 22, 24, namely to bring them closer, to realize them. That would be too e.g. via the detection of frequency shifts (Doppler effect) conceivable.

Die Toreinfahrt nach Figur 2 unterscheidet sich von derjenigen nach Figur 1 durch eine der Toreinfahrt 34 zugeordnete Näherungserfassungseinrichtung 32. Die Näherungserfassugnseinrichtung 32 weist eine Lichtschranke 36, eine Kontaktschwelle 38 oder einen Bewegungsmelder 40 auf, wobei in dem dargestellten Beispiel zur Darstellungszwecken der Einfachheit halber aller diese Einrichtungen gezeigt sind, auch wenn in praktisch realisierten Ausführungen eine dieser Einrichtungen 36, 38, 40 ausreichend sein mag.The gate entrance according to FIG. 2 differs from that according to FIG. 1 by a proximity detection device assigned to the gate entrance 34 32.

Die Lichtschranke 36, die Kontaktschwelle 38 und der Bewegungsmelder 40 sind jeweils dazu ausgelegt, ein Annähern eines Fahrzeugs (oder einer Person) zu dem Tor 12 festzustellen und bei einer solchen Annäherung ein Signal an die Steuerschaltung 16 abzugeben. Die Steuerschaltung 16 veranlaßt daraufhin den stationären Sendeempfänger 22, ein Codeabfragesignal 42 in den Bereich der Toreinfahrt 34 hinein abzusenden. Befindet sich der berechtigte mobile Sendeempfänger 24 im Bereich der Toreinfahrt, so empfängt er das Codeabfragesignal 42 und sendet ein passendes Codeantwortsignal 44, bei dessen Empfang die Steuerschaltung 16 eine Toröffnungsbewegung über den Motor 14 einleitet.The light barrier 36, the contact threshold 38 and the motion detector 40 are each designed to approach a vehicle (or a vehicle) Person) to the gate 12 and at such an approach To deliver signal to the control circuit 16. The control circuit 16 then causes the stationary transceiver 22, a To send the code query signal 42 into the area of the gate entrance 34. The authorized mobile transceiver 24 is in the range of Entrance, he receives the code request signal 42 and sends one matching code response signal 44, upon receipt of which the control circuit 16 initiates a door opening movement via the motor 14.

Es können verschiedene Zusatzmaßnahmen vorgesehen sein, um ein ersehentliches Öffnen bei Annähern eines nichtberechtigten Fahrzeugs und Vorhandenseins des mobilen Sendeempfängers 24 in der Nähe der Toreinfahrt 34 zu vermeiden. Diese Maßnahmen können z.B. darin bestehen, daß Richtfunkeinrichtungen feststellen, von wo her das Codeantwortsignal 44 gesendet wird und eine Toröffnungsbewegung verhindern, wenn das Codeantwortsignal 44 nicht aus dem unmittelbaren Bereich der Toreinfahrt 34 heraus erfolgt. Andererseits könnten die beiden Ausführungsformen miteinander kombiniert sein, so daß nur dann eine Toröffnung erfolgt, wenn gleichzeitig eine Relativbewegung der mobilen und der stationären Einheit durch die Signalauswerteschaltung A festgestellt wird. Schließlich könnte der mobile Sendeempfänger 24 an das Bordnetz des Fahrzeugs 20 und insbesondere an dessen Zündung angeschlossen sein, so daß nur dann ein Codeantwortsignal 44 abgegeben wird, wenn die Zündung des Fahrzeugs eingeschaltet ist. Vorteilhaft kann auch ein Codesignalaustausch über andere Medien als Funk sein, z.B. über Lichtsignale, die nur bei passender Ausrichtung des Fahrzeugs 20 in der Toreinfahrt 34 empfangbar sind.Various additional measures can be provided in order to accidental opening when an unauthorized vehicle approaches and Presence of the mobile transceiver 24 near the Avoid gate entrance 34. These measures can e.g. consist in that directional radio devices determine from where the code answer signal 44 is sent and prevent a gate opening movement if that Code response signal 44 not from the immediate area of the gate 34 done out. On the other hand, the two embodiments could be combined with each other so that the door only opens when at the same time a relative movement of the mobile and the stationary unit is determined by the signal evaluation circuit A. After all, the mobile transceiver 24 to the vehicle electrical system 20 and in particular, be connected to its ignition, so that only then Code response signal 44 is emitted when the ignition of the vehicle is switched on. A code signal exchange via others can also be advantageous Media as radio, e.g. via light signals that only match Alignment of the vehicle 20 can be received in the gate entrance 34.
