Abstract

The system has each locked door provided with a read/write station, which verifies an entered key code to allow automatic opening of the door, at least one of the read/write stations coupled to a network, for interchange of information between the read/write terminals and/or an evaluation device, e.g. a personal computer. The network may be provided by a longtalk protocol network used for allowing synchronisation of the rolling codes, provided by different bit code patterns.

Description

Die Erfindung betrifft ein Türöffnungssystem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a door opening system according to the Preamble of claim 1.

Schlüssellose Türöffner-Systeme sind im Stand der Technik bekannt, vgl. dazu das in der Zeitschrift EAM 6/95 beschrie­ bene easy key (eingetragene Marke) -Türöffner-System. Durch diese Bezugnahme ist die Beschreibung dieses Türöffner-Sys­ tems in die Offenbarung der vorliegenden Anmeldung mitauf­ genommen.Keyless door opener systems are state of the art known, cf. this is described in the magazine EAM 6/95 bene easy key (registered trademark) door opener system. By this reference is the description of this door opener system tems in the disclosure of the present application taken.

Insbesondere ein aus Sicherheitsgründen erstrebenswerter Einsatz von sogenannten Wechselcodes (hopping codes, rolling codes) ist bei mehreren unabhängigen Schreib/Lesestationen eines Gebäudes mit mehreren zutrittsbeschränkten Bereichen dahingehend problematisch, daß nach dem erfolgreichen Passieren eines Bereichs der Wechselcode nicht mit einer anderen Schreib/Lesestation synchronisiert ist. Daher muß der Benutzer, wenn er in einen anderen Bereich eintreten will, seinen Code mit der entsprechenden Schreib/Lesestation synchronisieren.In particular, one that is desirable for security reasons Use of so-called change codes (hopping codes, rolling codes) is with several independent read / write stations of a building with several restricted areas problematic in that after the successful Do not pass an area of the change code with one other read / write station is synchronized. Therefore the user when he enter another area wants his code with the appropriate read / write station synchronize.

Der Erfindung liegt daher die Aufgabe zugrunde, die Nach­ teile des Standes der Technik zu vermeiden, und insbesondere neue Anwendungsgebiete und mehr Flexibilität für ein Tür­ öffner-System, insbesondere unter Verwendung von Wechselco­ des, zu schaffen.The invention is therefore based on the object to avoid parts of the prior art, and in particular new areas of application and more flexibility for one door opener system, especially using Wechselco of creating.

Insbesondere bei einem Einsatz von Wechselcodes kann durch entsprechende Datenübertragung durch das Netzwerk erreicht werden, daß jede Schreib/Lesestation den aktuellen zum Zu­ gang berechtigenden Code kennt.In particular, when using alternating codes, Appropriate data transmission through the network achieved be that each read / write station the current to the Zu knows the code that authorizes access.

Die erfindungsgemäße Aufgabe wird bei einem Türöffnungssys­ tem der eingangs genannten Art durch das im kennzeichnenden Teil des Anspruchs 1 enthaltene Merkmal gelöst. The object of the invention is in a door opening system tem of the type mentioned at the beginning by the in the characterizing Feature contained part of claim 1 solved.  

Bevorzugte Ausführungsformen der Erfindung sind in den ab­ hängigen Patentansprüchen offenbart.Preferred embodiments of the invention are in the ab pending patent claims disclosed.

Die Erfindung sowie weitere Ausgestaltungen und Vorteile derselben wird bzw. werden nachfolgend anhand von Aus­ führungsbeispielen unter Bezugnahme auf die Zeichnung er­ läutert. In der Zeichnung zeigt:The invention and further refinements and advantages the same will be based on Aus management examples with reference to the drawing he purifies. The drawing shows:

Fig. 1 ein Ausführungsbeispiel des Einsatzes des erfindungs­ gemäßen Türöffnungssystems; und Figure 1 shows an embodiment of the use of the door opening system according to the Invention. and

Fig. 2 eine schematische Darstellung eines Ausführungsbei­ spiels einer Schreib/Lese-Station des erfindungsge­ mäßen Türöffnungssystems. Fig. 2 is a schematic representation of an exemplary embodiment of a read / write station of the door opening system according to the invention.

In Fig. 1 ist ein Ausführungsbeispiel des Einsatzes des er­ findungsgemäßen Türöffnungssystems schematisch dargestellt. In einzelnen Abteilungen (Geschäftsleitung, Controlling, Entwicklung, Fertigung . . .) eines Betriebs sind an den Ein­ gangstüren Terminals (vgl. Fig. 2 und die zugehörige Be­ schreibung) angebracht. Die Terminals weisen die für den berührungslos arbeitenden Türöffner nötigen Komponenten auf. Außerdem sind die Terminals mittels einer LON-Schnittstelle über die 230 V Netzleitung miteinander verbunden und kommu­ nizieren miteinander oder mit weiteren LONTALK-Knoten über das sogenannte LONTALK-Protokoll. Ein PC mit LON-Schnitt­ stelle und Datenbank ist zur Auswertung und Ansteuerung der Terminals sowie weiterer Aktoren und Stellglieder vorge­ sehen. Der PC dient beispielsweise zur Zeiterfassung der Mitarbeiter. Die notwendige Identifizierung der Mitarbeiter wird dabei durch den beim Zugang durch einen Transponder be­ reitgestellten Code geliefert (vgl. EAM 6/95) und die erfaß­ ten Daten werden in der Datenbank des PC gespeichert.In Fig. 1 an embodiment of the use of the inventive door opening system is shown schematically. In individual departments (management, controlling, development, production ...) of a company, terminals are attached to the entrance doors (cf. Fig. 2 and the associated description). The terminals have the components required for the contactless door opener. In addition, the terminals are connected to each other by means of a LON interface via the 230 V mains cable and communicate with each other or with other LONTALK nodes using the so-called LONTALK protocol. A PC with LON interface and database is provided for evaluating and controlling the terminals as well as other actuators and actuators. The PC is used, for example, to record employee time. The necessary identification of the employees is provided by the code provided upon access by a transponder (cf. EAM 6/95) and the data recorded are stored in the PC database.

Ferner kann der PC weitere Funktionen durchführen, wie z. B. individuelle Zutrittsberechtigungen zu erstellen oder aufzu­ heben, oder Licht oder weitere Geräte beim Betreten eines Raumes ein- oder auszuschalten. Furthermore, the PC can perform other functions, such as. B. create or open individual access authorizations lift, or light or other devices when entering one Switch room on or off.  

In Fig. 2 ist eine schematische Darstellung eines Aus­ führungsbeispiels einer Schreib/Lese-Station des erfindungs­ gemäßen Türöffnungssystems gezeigt. Das Terminal 1 weist neben den für das berührungslose Türöffnungssystem notwendi­ gen stationären Komponenten (vgl. EAM 6/95) eine numerische Tastatur 2 und eine Anzeige 3 auf. Über die Anzeige 3 oder einen (nicht dargestellten) Summer können anwenderbezogene Nachrichten an eine eintretende Person nach deren Identi­ fikation übermittelt werden oder anwenderbezogene Hand­ lungen, z. B. Einschalten eines Geräts, das für den Anwender bestimmt ist und dessen Identifikation verlangt, veranlaßt werden.In Fig. 2 is a schematic representation of an exemplary embodiment from a read / write station of the door opening system according to the Invention is shown. In addition to the stationary components necessary for the contactless door opening system (see EAM 6/95), Terminal 1 has a numeric keyboard 2 and a display 3 . Via the display 3 or a (not shown) buzzer, user-related messages can be transmitted to an incoming person after their identification, or user-related actions, e.g. B. switching on a device that is intended for the user and requires identification.

Die Erfindung wurde anhand bevorzugter Ausführungsbeispiele erläutert. Dem Fachmann sind jedoch zahlreiche Abwandlungen und Ausgestaltungen möglich, ohne daß dadurch der der Erfin­ dung zugrundeliegende Gedanke verlassen wird.The invention was based on preferred exemplary embodiments explained. However, numerous modifications are known to the person skilled in the art and configurations possible, without thereby the inventor underlying thought is left.
