Abstract

The system programs the key (7) for a limited period by the pin programming system (1), in which the key is assigned an associated PIN. The key in the pref. design can communicate with the PIN system using light pulses, inductances or similar. The microprocessor chip (2) of the key (7) is limited in time, and in the pref. design the PIN is limited for a set period using a quartz timer. The key in normal use, is separated from the PIN programming system (1). ADVANTAGE - Key is suitable for limited time, outside this time key is useless for obtaining entry. Gives enhanced security.

Description

Vom gleichen Anmelder wurden bereits mehrere Schutzrechtsanmeldungen getätigt, die sich mit der Problematik von elektronischen Schließsystemen beschäftigen .Several of the same applicant have already been Property rights registrations made with the Problems with electronic locking systems employ .

Ein wesentlicher Bestandteil dieser elektronischen Schließsysteme bildet ein Schlüssel mit Mikroprozessor- Chip, der in bevorzugter Ausführungsform einen Zuordnungscode aufweist und damit die Legitimation für entsprechend programmierte Schließanlagen oder Schlösser bzw. Schließzylinder darstellt.An essential part of this electronic Locking systems form a key with microprocessor Chip that in a preferred embodiment Assignment code and thus the legitimation for appropriately programmed locking systems or Represent locks or lock cylinders.

Ein wesentlicher Nachteil ist jedoch darin zu sehen, daß der Schlüssel verlustig oder gestohlen werden kann, so daß in der Zeitspanne bis zur Umprogrammierung bzw. bis zur Löschung des Zugangscodes entsprechender Schaden von einem unlegitimierten Schlüsselbesitzer angerichtet werden kann.However, a major disadvantage is that that the key can be lost or stolen, so that in the period until reprogramming or until the access code is deleted Damage from an illegitimate key owner can be served.

Schutz gegen diesen Mißbrauch bietet die sogenannte PIN, die jedoch in normaler Verfahrensweise dem jeweiligen Anwendungsbestandteil bevorzugt mittels alpha-numerischer Tastatur eingegeben wird.Protection against this abuse is provided by the so-called PIN, which, however, in the normal procedure the respective application component preferably by means of alpha-numeric keyboard is entered.

Bei der Verwendung von Schlüsseln ist eine solche PIN- Eingabe problematisch, zumal wenn ältere Personenkreise damit konfrontiert werden.When using keys, such a PIN Entry problematic, especially when older people to be faced with it.

Sinn und Zweck der hier vorgestellten Erfindung ist es daher, eine Vorrichtung vorzustellen, die es erlaubt, mittels einfachen Knopfdrucks die PIN bevorzugt zeitbegrenzt in den Schlüssel zu übertragen und ihn damit ebenfalls zeitlich begrenzt zu legitimieren. It is the purpose of the invention presented here therefore to present a device that allows preferred the PIN by simply pressing a button time-limited in the key and transfer it legitimize it for a limited time.  

In bevorzugter Ausführungsform wird dabei eine Programmiervorrichtung, die einen Mikroprozessor-Chip simpler Ausführungsart enthält, der lediglich durch den Schlüssel kontaktiert wird und der damit seine PIN dem Schlüssel mitteilt, die bevorzugt quarzgesteuert zeitlich begrenzt funktionsbereit gestellt wird.In a preferred embodiment, a Programming device using a microprocessor chip contains a simple design that is only available through the Key is contacted and the PIN Communicates key, which is preferably quartz-controlled is provided for a limited period of time.

Unter der Voraussetzung, daß der Festspeicher-PIN-Wert der beschriebenen Vorrichtung z. B. mittels EEPROMs umprogrammierbar als Festspeicherwert abgelegt ist, kann dieser z. B. durch Energiezufuhr und damit "Wecken" des Chips abgerufen werden, so daß der Chip selbst dann die PIN überträgt und den Schlüssel, wie gesagt, zeitlich begrenzt legitimiert.Provided that the permanent PIN value the device described z. B. using EEPROMs is reprogrammable stored as a fixed memory value, can this z. B. by supplying energy and thus "Wake up" the chip can be accessed, leaving the chip even then transmits the PIN and the key like said, legitimized for a limited time.

Nach Ablauf der Zeitkomponente wird der Schlüssel für jeden Anwender nutzlos, so daß auch für den normal Zugangsberechtigten die Sicherheit besteht, daß mit dem Schlüssel selbst kein Mißbrauch zu treiben ist.After the time component expires, the key for useless every user, so that even for the normal Authorized access the security exists that with the Key itself is not to be misused.

In bevorzugter Ausführungsform wird die PIN hier digital mit Lichtimpulsen übertragen und vom Schlüssel­ mikroprozessor aufgenommen und als legitim erkannt.In a preferred embodiment, the PIN is here digitally transmitted with light impulses and from the key microprocessor recorded and recognized as legitimate.

Der Schlüssel selbst tätigt im Anschluß die in ausreichender Form beschriebenen Vorrichtungsbeispiele des Schlosses bzw. Schließzylinders.The key itself then does the in Device examples described in sufficient form of the lock or lock cylinder.

Die Erfindung wird nun anhand der Ansprüche 1-10 und der Fig. 1 näher erläutert.The invention will now be explained in more detail with reference to claims 1-10 and FIG. 1.

Dabei zeigt Fig. 1 in schematisierter Anordnung die Verbindung eines Schlüssels mit der angesprochenen PIN- Programmiervorrichtung. Here, FIG. 1 in a schematic arrangement showing the connection of a key with the PIN-mentioned teaching device.

Fig. 1 zeigt in schematisierter Anordnung die Verbindung von Schlüssel (7) mit der PIN- Programmiervorrichtung (1). Diese ist mit Mikroprozessor-Chip (2) versehen, wobei in der Anwendung dieser hier mittels LED (3) bzw. Photodiode (4) mit dem Schlüsselbartanteil (5) korrespondiert. Fig. 1 shows a schematic arrangement of the connection of key ( 7 ) with the PIN programming device ( 1 ). This is provided with a microprocessor chip ( 2 ), the use of which corresponds here to the key bit portion ( 5 ) by means of LED ( 3 ) or photodiode ( 4 ).

Dies bedeutet im Klartext, daß über die LED (3) dem Schlüssel (7) mit seinem Mikroprozessor die PIN zugespielt wird, die quarzgesteuert für einen bestimmten Zeitraum gehalten wird.This means in plain text that the key (7) is played back with its microprocessor, the PIN using the LED (3), which is crystal controlled for a certain period held.

Das Figurenmerkmal (6) dient lediglich als Drehmomentübertragungselement und hat für die eigentliche Funktion der PIN-Übertragung wenig Bedeutung.The figure feature ( 6 ) serves only as a torque transmission element and is of little importance for the actual function of the PIN transmission.
