Abstract

What is described is an access control device for doors which are equipped with an electrical door opener (11). To prevent an unauthorised actuation of the door opener, for example by applying a supply voltage, each door opener is activated from a central control unit (10) by means of an individual selection code. The absence of any coincidence between the transmitted selection code and a code preset in the door opener prevents the possibility of actuation. <IMAGE>

Description

Die Erfindung betrifft eine Zugangs-Kontrollvorrichtung mit einem elektrischen Türöffner einerseits, der eine Schwenkfalle, einen lösbaren Riegel für die Schwenkfalle, einen mit dem Riegel zusammenwirkenden Elektromagnet und einen Statusmelder zur Überwachung des Offen-/Geschlossen-Zustandes des betreffenden Zugangs aufweist, sowie eine Steuerzentrale andererseits, die über eine Versorgungsleitung mit dem Türöffner und über eine Signalleitung mit dem Statusmelder verbunden ist.The invention relates to an access control device with an electric door opener on the one hand, which has a swivel latch, a releasable latch for the swivel latch, an electromagnet interacting with the latch and a status indicator for monitoring the open / closed state of the access concerned, and a control center on the other hand, which is connected to the door opener via a supply line and to the status detector via a signal line.

Derartige Zugangs-Kontrollvorrichtungen werden bekanntlich zur Sicherung und Überwachung von abgeschlossenen Bereichen in Gebäuden und im Freien eingesetzt. Es soll sichergestellt werden, daß diesen Bereich nur Berechtigte betreten oder verlassen, wobei die Kontrolle ständig erfolgen oder auf bestimmte Zeitabschnitte beschränkt sein kann. Die Zu- und Ausgänge, sind zu diesem Zweck mit mechanischen Stellgliedern versehen, beispielsweise Drehkreuzen, Türen oder Tore. Deren Steuerung erfolgt durch elektrische Türöffner, die mit einer Steuerzentrale verbunden sind. Zur Überwachung des Zustandes des Stellgliedes sind ferner Rückmelder vorhanden, welche den Zustand "offen" oder "geschlossen" an die Steuerzentrale melden.Such access control devices are known to be used to secure and monitor closed areas in buildings and outdoors. It is to be ensured that only authorized persons enter or leave this area, the control being carried out continuously or being restricted to certain time segments. For this purpose, the entrances and exits are provided with mechanical actuators, for example turnstiles, doors or gates. They are controlled by electrical door openers that are connected to a control center. To monitor the status of the actuator there are also feedback devices which report the status "open" or "closed" to the control center.

Die zu diesem Zweck bekannten elektrischen Türöffner werden durch Aufschaltung einer Gleich- oder Wechselspannung freigegeben bzw. verriegelt. Hierzu stehen sie über Versorgungsleitungen mit der Steuerzentrale in Verbindung. Derartige Türöffner haben sich in der Praxis sehr gut bewährt.The electrical door openers known for this purpose are released or locked by applying a DC or AC voltage. For this purpose, they are connected to the control center via supply lines. Such door openers have proven themselves very well in practice.

Allerdings ist es erforderlich, die Versorgungsleitungen mechanisch gegen Sabotageversuche zu schützen, die darin bestehen könnten, die Leitungen an einer Stelle freizulegen und mit einer Spannung zu beaufschlagen. Auf diese Weise könnte der betreffende Türöffner betätigt werden.However, it is necessary to mechanically protect the supply lines against attempts at sabotage, which could consist of exposing the lines at one point and applying a voltage to them. In this way, the door opener in question could be operated.

Darüber hinaus ist auch bekannt, einzelne Türen oder Tore oder vorgegebene Gruppen von Türen, beispielsweise im Rahmen einer Kraftfahrzeug-Zentralverriegelung, mit Hilfe einer Fernbedienung anzusteuern. Dabei wird über eine leitungslose Übertragungsstrecke ein kodiertes Signal von einem mobilen Sender zum betreffenden Schloß übertragen. Systembedingt ist eine derartige Schließvorrichtung nicht für die vorstehend beschriebenen Zugangs-Kontrollvorrichtungen geeignet.In addition, it is also known to control individual doors or gates or predetermined groups of doors, for example in the context of a motor vehicle central locking system, using a remote control. In this case, a coded signal is transmitted from a mobile transmitter to the lock in question via a line-free transmission path. Due to the system, such a locking device is not suitable for the access control devices described above.

Der Erfindung liegt die Aufgabe zugrunde, eine Zugangs-Kontrollvorrichtung der eingangs genannten Art anzugeben, die gegen eine in Sabotageabsicht manipulierte Beaufschlagung der Versorgungsleitungen geschützt ist.The invention is based on the object of specifying an access control device of the type mentioned at the outset, which is protected against manipulation of the supply lines which is manipulated with the intention of sabotage.

Diese Aufgabe wird dadurch gelöst, daß die Steuerzentrale einen Sender zum Aussenden von kodierten Türöffner-Steuersignalen ("Türöffner freigeben" oder "Türöffner sperren") aufweist, die über die Signalleitung an den Türöffner übertragen werden, daß die Steuerzentrale ferner eine mit einer Verzögerungsanordnung zusammenwirkende Auswerteeinheit umfaßt, die eingangsseitig mit der Signalleitung zum Empfang des Statussignals verbunden ist, und welche nach dem Aussenden eines "Türöffner-freigeben"-Signals zumindest nach Ablauf einer vorgegebenen Zeit die Aussendung eines "Türöffner-sperren"-Signals bewirkt, daß der Schwenkfallen-Riegel bistabil und zur Einnahme seiner zwei Zustände ansteuerbar ist, und daß türöffnerseitig ein mit der Signalleitung verbundener Dekodierer vorhanden ist, über dessen Ausgangssignal der bistabile Riegel angesteuert wird.This object is achieved in that the control center has a transmitter for transmitting coded door opener control signals ("release door opener" or "lock door opener"), which are transmitted via the signal line to the door opener, in that the control center also interacts with a delay arrangement Includes evaluation unit, which is connected on the input side to the signal line for receiving the status signal, and which after the transmission of a "door opener release" signal, at least after a predetermined time has elapsed, the transmission of a "door opener lock" signal causes the swing latch Bolt is bistable and can be controlled to assume its two states, and that a decoder connected to the signal line is present on the door opener side, via the output signal of which the bistable bolt is controlled.

Die Erfindung hat den Vorteil, daß die Ansteuerung des Türöffners über verschlüsselte Signale erfolgt, so daß es ausgeschlossen ist, den Türöffner durch Auflegen der Versorgungsspannung freizuschalten. Es erübrigt sich daher, die Versorgungsleitung aufwendig mechanisch zu schützen. Dies gilt auch für die Signalleitungen, da in Unkenntnis des Steuerkodes eine Türöffner-Freischaltung ausgeschlossen ist, selbst wenn die Signalleitung unmittelbar zugänglich ist.The invention has the advantage that the door opener is controlled via encrypted signals, so that it is impossible to unlock the door opener by applying the supply voltage. It is therefore unnecessary to protect the supply line mechanically. This also applies to the signal lines, because if the control code is not known, the door release cannot be activated, even if the signal line is directly accessible.

Ein weiterer Vorteil ist darin zu sehen, daß keine zusätzlichen Leitungen erforderlich sind, da die herkömmliche, zur Statusmeldung verwendete Signalleitung bidirektional genutzt wird. Bereits vorhandene Systeme können daher auf einfache Weise nachgerüstet werden. Andererseits können alternativ mehrere Türöffner parallel an einen Leitungsstrang gelegt werden.Another advantage is that no additional lines are required since the conventional signal line used for status reporting is used bidirectionally. Existing systems can therefore be easily upgraded. On the other hand, several door openers can alternatively be placed in parallel on one cable run.

Die Sicherheit gegen unbefugtes Betreten der geschützten Räume ist besonders zuverlässig gewährleistet, da der Türöffner nach einer gewissen Zeit wieder gesperrt wird, wenn bis dahin die betreffende Tür nicht geöffnet bzw. der Türöffner nicht betätigt wurde.Security against unauthorized entry into the protected rooms is ensured particularly reliably, since the door opener is locked again after a certain time if the door in question has not been opened or the door opener has not been actuated by then.

Eine bevorzugte Weiterbildung der Erfindung besteht darin, daß über die Auswerteeinheit die Aussendung des "Türöffner-sperren"-Signals bewirkt wird, sobald das Statussignal "Türe bzw. Türöffner wurde betätigt" über die Signalleitung empfangen wurde. Auf diese Weise wird verhindert, daß der gesicherte Zugang von einem Unberechtigten benutzt werden kann, wenn er einem Zugangsberechtigten in kurzem Abstand nachfolgt.A preferred development of the invention consists in that the "lock release" signal is transmitted via the evaluation unit as soon as the status signal "door or lock has been actuated" has been received via the signal line. This prevents secured access from being used by an unauthorized person if he succeeds an authorized person at short intervals.

Besonders vorteilhaft ist es, daß am Dekodierer wahlweise unterschiedliche Kodes einstellbar sind. Durch diese Maßnahme kann jeder Türöffner auf die Steuerzentrale abgestimmt werden. Damit ist ausgeschlossen, daß ein bestimmter Türöffner über eine andere Steuerzentrale beeinflußt werden kann.It is particularly advantageous that different codes can optionally be set on the decoder. This measure allows each door opener to be coordinated with the control center will. This rules out the possibility that a specific door opener can be influenced via another control center.

Grundsätzlich ist es möglich, den Referenzkode des Dekodierers über die Steuerleitung zu programmieren, so daß eine Kodeänderung und gleichzeitge Abstimmung mit der Steuerzentrale bei Bedarf zu jeden Zeitpunkt vorgenommen werden kann. Besonders einfach und kostengünstig kann eine eindeutige Zuordnung von Steuerzentrale und Türöffner dadurch hergestellt werden, daß jeder Türöffner einen mechanischen Kodierschalter (DIL-Schalter) aufweist, der bei der Türöffner-Installation eingestellt wird. Die damit erzielbaren Kodevarianten sind so groß, daß zuverlässig eine unerwünschte gegenseitige Beeinflussung mehrerer Steuerzentralen ausgeschlossen wird.In principle, it is possible to program the reference code of the decoder via the control line, so that a code change and simultaneous coordination with the control center can be carried out at any time if required. A clear assignment of the control center and door opener can be made particularly simply and inexpensively in that each door opener has a mechanical coding switch (DIL switch) which is set during the door opener installation. The code variants that can be achieved in this way are so large that an undesirable mutual influence of several control centers is reliably excluded.

Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles weiter beschrieben.The invention is described below with reference to an embodiment shown in the drawing.

Die einzige Figur zeigt schematisch ein Blockschaltbild einer Zugangs-Kontrollvorrichtung.The single figure shows schematically a block diagram of an access control device.

Wie die Figur veranschaulicht, umfaßt eine Zugangs-Kontrollvorrichtung eine Steuerzentrale 10, welche eine Vielzahl von elektrischen Türöffnern steuert und überwacht. Um die Figur übersichtlich zu halten, ist lediglich ein einziger Türöffner 11 wiedergegeben. Die Steuerzentrale 10 und der Türöffner 11 sind über eine Stromversorgungsleitung 12, eine bidirektionale Signalleitung 13 sowie eine Potentialausgleichsleitung 14 verbunden.As the figure illustrates, an access control device comprises a control center 10 which controls and monitors a plurality of electric door openers. To keep the figure clear, only a single door opener 11 is shown. The control center 10 and the door opener 11 are connected via a power supply line 12, a bidirectional signal line 13 and a potential equalization line 14.

Der Türöffner 11 weist eine Schwenkfalle (nicht dargestellt) auf, die über einen bistabilen Riegel 15 gesperrt oder freigegeben werden kann. Der Riegel 15 ist als zweiarmiger Kipphebel ausgebildet, und wird über eine Anordnung von zwei Elektromagneten 16,17 betätigt. Zum Umschalten des Türöffners von der Schließstellung in die Öffnungsstellung und umgekehrt wird der betreffende Magnet 16 bzw. 17 mit einem Stromimpuls beaufschlagt, so daß der Riegel die jeweils andere Stellung einnimmt, in der er von einer Blattfeder 18 lösbar gehalten ist.The door opener 11 has a swivel latch (not shown) which can be locked or released via a bistable latch 15. The bolt 15 is a two-armed Rocker arm formed, and is actuated via an arrangement of two electromagnets 16, 17. To switch the door opener from the closed position to the open position and vice versa, the relevant magnet 16 or 17 is acted upon by a current pulse, so that the bolt assumes the other position in which it is detachably held by a leaf spring 18.

Ferner ist türöffnerseitig ein Statusmelder 19 vorhanden, der die Offen- oder Geschlossen-Stellung der mit dem Türöffner 11 verbundenen Tür (nicht dargestellt) überwacht. Alternativ dazu kann mit dem Statusmelder 19 eine Betätigung der Schwenkfalle detektiert werden. Wenn die Türe geöffnet bzw. die Schwenkfalle bei einem Öffnungsvorgang ausgelenkt wurde, erzeugt der Statusmelder 19 ein Signal, welches über die Signalleitung 13 an die Steuerzentrale 10 übertragen wird.There is also a status indicator 19 on the door opener side, which monitors the open or closed position of the door (not shown) connected to the door opener 11. As an alternative to this, actuation of the swivel trap can be detected with the status indicator 19. When the door has been opened or the swivel latch has been deflected during an opening process, the status indicator 19 generates a signal which is transmitted to the control center 10 via the signal line 13.

Die Steuerzentrale 10 umfaßt einen Rechner mit einer Auswerteeinheit 20, beispielsweise einem Mikroprozessor, der über einen Sender 21 binarkodierte Steuersignale über die Signalleitung 13 an den Türöffner 11 sendet. In umgekehrter Richtung empfängt die Auswerteeinheit 20 das Statussignal.The control center 10 comprises a computer with an evaluation unit 20, for example a microprocessor, which sends binary-coded control signals via the signal line 13 to the door opener 11 via a transmitter 21. The evaluation unit 20 receives the status signal in the opposite direction.

Die Steuersignale werden türöffnerseitig von einem Dekodierer 22 entschlüsselt. Abhängig davon, ob ein "Türöffner-freigeben"- oder "Türöffner-schließen"-Signal ordnungsgemäß empfangen wird, steuert der Dekodierer 22 einen Schalter 23 an, und dieser legt über eine Leitung 24 bzw. 25 die Versorgungsspannung an einen der Magnete 16 bzw. 17, so daß dieser kurzzeitig erregt wird und der Riegel 15 betätigt wird.The control signals are decrypted on the door opener side by a decoder 22. Depending on whether a "release door opener" or "close door opener" signal is properly received, the decoder 22 controls a switch 23, and this switches the supply voltage to one of the magnets 16 or 25 via a line 24 or 25 17, so that it is briefly energized and the bolt 15 is actuated.

Die Steuersignale enthalten einen Auswahl-Kode, der ausschließlch dem betreffenden Türöffner 11 zugeordnet und dort festgelegt ist. Dies kann irreversibel durch eine feste Verdrahtung eingeprägt oder wahlweise änderbar sein. Jeder Türöffner kann somit individuell und verschlüsselt ausgewählt werden. Bei fehlender Übereinstimmung ist eine Betätigung des Türöffners 11 ausgeschlossen.The control signals contain a selection code which is exclusively assigned to the relevant door opener 11 and is fixed there. This can be irreversible through a Fixed wiring can be stamped or optionally changed. Each door opener can thus be selected individually and encrypted. If there is no match, actuation of the door opener 11 is excluded.

Der Dekodierer 22 steht in Verbindung mit einem Kodierschalter 26 (Mini-DIL-Schalter), an welchem der für den Türöffner 11 maßgebende Kode eingestellt wird. Eine Betätigung des Türöffners bzw. eine Erregung der Magnete 16,17 erfolgt nur dann, wenn über die Signalleitung 13 ein entsprechend kodiertes Steuersignal übertragen wird. Die Kode-Abstimmung zwischen der Steuerzentrale 10 und dem Türöffner 11 erfolgt grundsätzlich bei der Installation des Türöffners 11. Falls es jedoch erforderlich ist, kann auch zu einem späteren Zeitpunkt eine Anpassung oder Änderung vorgenommen werden.The decoder 22 is connected to a coding switch 26 (mini-DIL switch), on which the code relevant for the door opener 11 is set. The door opener is actuated or the magnets 16, 17 are energized only when a correspondingly coded control signal is transmitted via the signal line 13. The code coordination between the control center 10 and the door opener 11 takes place in principle when the door opener 11 is installed. However, if it is necessary, an adjustment or change can also be made at a later time.

Nachfolgend wird die Funktion der Zugangs-Kontrollvorrichtung anhand eines Beispiels erläutert. Als Ausgangssituation wird angenommen, daß der Türöffner 11 gesperrt ist. Wenn eine Zugangsberechtigung von einem Benutzer nachgewiesen wurde, überträgt die Steuerzentrale 10 das Steuersignal "Türöffner-freigeben" zusammen mit dem Türöffner-Kode. Dies bewirkt ein kurzzeitiges (ca. 100 ms) Auflegen der Spannung an den Magneten 16 und ein Umschalten des Riegels 15.The function of the access control device is explained below using an example. As an initial situation, it is assumed that the door opener 11 is locked. If access authorization has been verified by a user, the control center 10 transmits the control signal “release door release” together with the door release code. This causes a brief (approx. 100 ms) voltage to be applied to the magnet 16 and the latch 15 to be switched.

Für eine vorgegebene Zeit wird anschließend der Statusmelder 19 von der Auswerteeinheit 20 daraufhin überwacht, ob die Türe geöffnet wurde oder nicht. Erfolgt in dieser Zeit keine Türöffnung, sendet die Steuerzentrale 10 das kodierte Steuersignal "Türöffner-sperren" aus, was eine kurzzeitige Erregung des Magneten 17 und ein Umschalten des Riegels 15 in die "geschlossen-Stellung" bewirkt.For a predetermined time, the status indicator 19 is then monitored by the evaluation unit 20 to determine whether the door has been opened or not. If there is no door opening during this time, the control center 10 transmits the coded control signal “lock door opener”, which causes a brief excitation of the magnet 17 and a switching of the bolt 15 into the “closed position”.

Wird die Tür jedoch in dieser Überwachungszeit betätigt und vom Statusmelder 19 angezeigt, so wird das Steuersignal "Türöffner-sperren" umgehend ausgesendet und der Türöffner 11 wird in den Grundzustand versetzt.However, if the door is operated during this monitoring time and displayed by the status indicator 19, the control signal becomes "Lock door opener" is sent immediately and the door opener 11 is set to the basic state.
