Description

Die Erfindung betrifft einen Schlüssel mit einem Transponderchip und mit einer mit dem Transponderchip verbundenen Antenne zur Absendung von schlüsselspezifischen elektronischen Signalen.The invention relates to a key with a transponder chip and with an antenna connected to the transponder chip for sending key-specific electronic signals.

Ein solcher Schlüssel ist beispielsweise aus der DE 199 06 578 A1 bekannt. Bei diesem Schlüssel ist ein einzelner Codegeber in einem Schaft angeordnet. Der Schlüssel lässt sich in einen Schließkanal eines Schließzylinders einführen. Der Schließzylinder weist einen Codeempfänger mit einer Antenne auf. Die Antenne ist vor dem Codegeber des in den Schließkanal eingeführten Schlüssels angeordnet. Hierdurch kann der Codegeber des Schlüssels durch ein von der Antenne des Codeempfängers erzeugte elektromagnetische Feld mit elektrischer Energie versorgt und ausgelesen werden.Such a key is for example from the DE 199 06 578 A1 known. In this key, a single encoder is arranged in a shaft. The key can be inserted into a closing channel of a lock cylinder. The lock cylinder has a code receiver with an antenna. The antenna is arranged in front of the code transmitter of the key inserted into the lock channel. As a result, the code transmitter of the key can be supplied with electrical energy and read out by an electromagnetic field generated by the antenna of the code receiver.

Solche Codegeber weisen üblicherweise eine Antenne und einen Transponderchip auf, welche mit dem von der Antenne des Codeempfängers erzeugten elektromagnetischen Feld einen Schwingkreis bilden, über den elektrische Signale, wie einem auf dem Codegeber abgespeicherten Code, übertragen werden können. Die Antenne des bekannten Codegebers ist durch ihre Größe und Ausrichtung ausgelegt, um von einem Schließzylinder ausgelesen zu werden.Such code transmitters usually have an antenna and a transponder chip, which form a resonant circuit with the electromagnetic field generated by the antenna of the code receiver, via which electrical signals, such as a code stored on the code transmitter, can be transmitted. The antenna of the known encoder is designed by its size and orientation to be read by a lock cylinder.

Heutige Schließanlagen weisen neben Schließzylindern zum Einführen eines Schlüssels auch elektronische Sperreinrichtungen auf, die von einem Lesegerät angesteuert werden. Für solche Lesegeräte sind in Schlüsselanhängern und Scheckkarten angeordnete Codegeber bekannt geworden. Versucht man solche Lesegeräte mit Codeempfängern eines bekannten Schlüssels anzusteuern, hat dies den Nachteil, dass der Leseabstand sehr klein ist. Der Schlüssel muss daher mit der sehr kleinen, im Schaft befindlichen Antenne genau in der vorgesehenen Position des Lesegerätes gehalten werden. Dies ist jedoch sehr unkomfortabel.Today's locking systems have in addition to locking cylinders for inserting a key and electronic locking devices that are controlled by a reader. For such readers are in key fobs and Check cards arranged code transmitter become known. Attempting to drive such readers with code receivers of a known key, this has the disadvantage that the reading distance is very small. The key must therefore be held with the very small, located in the shaft antenna exactly in the intended position of the reader. However, this is very uncomfortable.

Man könnte daran denken, den Schlüssel mit einer großen und einer kleinen Antenne auszustatten. Dies führt jedoch dazu, dass sich bei einer gleichzeitigen Anregung beider Antennen deren Signale gegenseitig stören und bei einseitiger Anregung gegenseitig dämpfen.One might think of equipping the key with a large and a small antenna. However, this leads to the fact that their signals interfere with each other at a simultaneous excitation of both antennas and mutually attenuate in one-sided excitation.

Der Erfindung liegt das Problem zugrunde, einen Schlüssel der eingangs genannten Art so weiter zu bilden, dass er vielseitige Möglichkeiten zum Auslesen durch verschiedene Codeempfänger aufweist.The invention is based on the problem of further developing a key of the type mentioned at the beginning in such a way that it has versatile possibilities for reading out by different code receivers.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass eine zweite Antenne zur Absendung der schlüsselspezifischen elektronischen Signale mit dem Transponderchip verbunden ist, wobei die Antennen unterschiedliche Größen und/oder Ausrichtungen aufweisen und wobei der Transponderchip ausschließlich über eine der Antennen auslesbar ist.This problem is inventively solved in that a second antenna for sending the key-specific electronic signals is connected to the transponder chip, wherein the antennas have different sizes and / or orientations and wherein the transponder chip is exclusively readable via one of the antennas.

Durch diese Gestaltung lässt sich der Schlüssel zum Auslesen durch die verschiedenen Codeempfänger anpassen. Dabei kann, wenn es gefordert ist, eine dritte und weitere Antennen mit dem Transponderchip verbunden sein. Durch die unterschiedlichen Größen und Ausrichtungen kann eine der Antennen zum Vorhalten vor ein Lesegerät und die andere der Antennen zum Einführen in einen Schließzylinder ausgebildet sein. Im einfachsten Fall könnten die Antennen als Richtantennen ausgebildet sein oder sich in Art und Aufbau unterscheiden, so dass in Abhängigkeit von der Gestaltung des Lesegerätes automatisch die eine oder die andere Antenne angeregt wird. Selbstverständlich kann zwischen den Antennen auch eine Abschirmung zur Erzeugung der vorgesehenen unterschiedlichen Ausrichtungen der Antennen angeordnet sein.This design allows the key to be read by the various code receivers. In this case, if required, a third and further antennas may be connected to the transponder chip. Due to the different sizes and orientations, one of the antennas may be designed to be held in front of a reading device and the other of the antennas to be inserted into a locking cylinder. In the simplest case, the antennas could be designed as directional antennas or art and structure differ so that automatically one or the other antenna is excited depending on the design of the reader. Of course, a shield for generating the intended different orientations of the antennas may be arranged between the antennas.

Gegenseitige Störungen oder Dämpfungen der über die Antennen abgestrahlten Signale lassen sich gemäß einer vorteilhaften Weiterbildung der Erfindung besonders zuverlässig vermeiden, wenn der Transponderchip ausschließlich über eine der Antennen auslesbar ist.Mutual interference or attenuation of the signals radiated via the antennas can be particularly reliably avoided according to an advantageous development of the invention, if the transponder chip can be read exclusively via one of the antennas.

Die von einem äußeren Feld angeregte Antenne wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung selbständig mit dem Transponderchip verbunden, wenn zwischen dem Transponderchip und den Antennen jeweils eine elektronische Schaltung angeordnet ist und wenn die elektronischen Schaltungen zur ausschließlichen Verbindung der Energie führenden Antenne mit dem Transponderchip ausgebildet ist. Durch diese Gestaltung lassen sich herkömmliche Transponderchips einsetzen. Die nicht angeregte Antenne wird dank der Erfindung nicht mit dem Transponderchip verbunden, wodurch die Störung des Signals der anderen Antenne vermieden wird.The excited by an external field antenna is independently connected to the transponder chip according to another advantageous embodiment of the invention, when between the transponder chip and the antennas each an electronic circuit is arranged and when the electronic circuits for exclusive connection of the energy-carrying antenna formed with the transponder chip is. This design allows conventional transponder chips to be used. The non-excited antenna is not connected thanks to the invention with the transponder chip, whereby the interference of the signal of the other antenna is avoided.

Der bauliche Aufwand zum wahlweisen Auslesen des Transponderchips über die eine oder die andere Antenne lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn der Transponderchip für jede der im Schlüssel vorhandenen Antennen einen separaten Gleichrichter aufweist. Durch diese Gestaltung sind die Bauteile zur Versorgung des Transponderchips mit elektrischem Strom und zur ausschließlichen Verbindung des Transponderchips mit der jeweiligen Antenne in dem Transponderchip selbst integriert. Dies führt zudem zu einer hohen Reichweite zum Auslesen des Transponderchips, weil externe elektronische Bauteile hierdurch vermieden werden.The structural complexity for selectively reading out the transponder chip via the one or the other antenna can be kept particularly low according to another advantageous development of the invention, if the transponder chip has a separate rectifier for each of the existing in the key antennas. As a result of this configuration, the components for supplying the transponder chip with electric current and for the exclusive connection of the transponder chip to the respective antenna are integrated in the transponder chip itself. This also leads to a high range for reading the transponder chip, because external electronic components are thereby avoided.

Die Unterschiede der Größe und Ausrichtung der Antennen lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach herstellen, wenn eine der Antennen als Ferritantenne ausgebildet und die andere Antenne großflächig gestaltet ist.The differences in the size and orientation of the antennas can be easily produced according to another advantageous embodiment of the invention, when one of the antennas is designed as a ferrite antenna and the other antenna is designed over a large area.

Häufig werden bei elektronischen Schließanlagen Lesegeräte eingesetzt, bei welchen der Transponderchip über große Entfernungen ausgelesen werden soll und Schließzylinder, bei welchen der Transponderchip nur ausgelesen wird, wenn der Schlüssel in einen Schließkanal eingeführt wird. Der Schlüssel eignet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung für unterschiedliche Anwendungsumgebungen, wenn eine der Antennen in einem zum Einführen in einen Schließkanal eines Schließzylinders vorgesehenen Schaft und die andere der Antennen in einer zum Greifen mit der Hand vorgesehenen Reide angeordnet ist.Frequently electronic readers are used in which the transponder chip is to be read over long distances and lock cylinder, in which the transponder chip is only read when the key is inserted into a lock channel. The key is according to another advantageous embodiment of the invention for different application environments, when one of the antennas is arranged in a provided for insertion into a lock channel of a lock cylinder shaft and the other of the antennas in a gripping hand intended Reide.

An seinen Stirnseiten weist der Kern 3 jeweils einen Schließkanal 5 zum Einführen eines Schlüssels 6 auf. Der Schließzylinder 1 hat eine elektromagnetische Sperreinrichtung 7 zur wahlweisen Blockierung oder Freigabe der Bewegung des Kerns 3 gegenüber dem Gehäuse 2. In einem von der Stirnseite des Schließzylinders 1 entfernten Bereich des Gehäuses 2 ist eine Empfangsantenne 8 angeordnet. Die Empfangsantenne 8 ist mit einer Steuereinrichtung 9 verbunden, welche die elektromagnetische Sperreinrichtung 7 ansteuert. In dem Gehäuse 2 ist zudem ein als Knopfzelle ausgebildeter Energiespeicher 10 angeordnet. Der Energiespeicher 10 versorgt die Steuereinrichtung 9 und die Sperreinrichtung 7 mit elektrischer Energie. FIG. 1 shows a lock cylinder 1 with a rotatably mounted in a housing 2 core 3. The core 3 is rotatably connected to a cam 4. At its end faces, the core 3 each have a closing channel 5 for insertion of a key 6. The lock cylinder 1 has an electromagnetic locking device 7 for selectively blocking or releasing the movement of the core 3 relative to the housing 2. In a remote from the end face of the lock cylinder 1 region of the housing 2, a receiving antenna 8 is arranged. The receiving antenna 8 is connected to a control device 9, which controls the electromagnetic locking device 7. In the housing 2 also designed as a coin cell energy storage 10 is arranged. The energy storage device 10 supplies the control device 9 and the blocking device 7 with electrical energy.

Der Schlüssel 6 hat einen dem Schließkanal 5 entsprechend gestalteten Schaft 11 und eine Reide 12 als Handgriff. Im Schaft 11 des Schlüssels 6 ist ein Codegeber 13 angeordnet. Der Codegeber 13 hat einen Transponderchip 14 mit zwei daran angeschlossenen Antennen 15, 16. Eine erste Antenne 15 hat kleine Abmessungen und ist in dem Schaft 11 angeordnet. Diese Antenne 15 steht der im Schließzylinder 1 angeordneten Empfangsantenne 8 gegenüber. Die erste Antenne 15 hat damit die Größe und die Ausrichtung, mit der Empfangsantenne 8 im Schließzylinder 1 zusammen zu wirken. Eine zweite Antenne 16 des Schlüssels 6 weist große Abmessungen auf und ist in der Reide 12 angeordnet. Diese zweite Antenne 16 wird nicht angeregt, wenn der Transponderchip 14 über die erste Antenne 15 ausgelesen wird. Die in dem Schaft 11 angeordnete Antenne 15 kann beispielsweise als Ferritantenne ausgebildet sein, während die in der Reide 12 angeordnete Antenne 16 großflächig gestaltet ist.The key 6 has a closing channel 5 correspondingly shaped shaft 11 and a Reide 12 as a handle. In the shaft 11 of the key 6, a code transmitter 13 is arranged. The code transmitter 13 has a transponder chip 14 with two antennas 15, 16 connected thereto. A first antenna 15 has small dimensions and is arranged in the shaft 11. This antenna 15 is opposite to the arranged in the lock cylinder 1 receiving antenna 8. The first antenna 15 thus has the size and the orientation to act together with the receiving antenna 8 in the lock cylinder 1. A second antenna 16 of the key 6 has large dimensions and is arranged in the Reide 12. This second antenna 16 is not excited when the transponder chip 14 is read out via the first antenna 15. The arranged in the shaft 11 antenna 15 may be formed, for example, as a ferrite antenna, while arranged in the Reide 12 antenna 16 is designed over a large area.

Diese Leseeinrichtung 17 steuert eine schematisch dargestellte Zutrittskontrollanlage 19 an. Bewegt man den Schlüssel 6 in die Nähe und damit in den Empfangsbereich der Leseeinrichtung 17, wird zunächst die die großen Abmessungen aufweisende und in Figur 1 dargestellte zweite Antenne 16 des Schlüssels 6 angeregt. Damit wird der Transponderchip 14 über die zweite Antenne 16 des Schlüssels 6 ausgelesen. FIG. 1a schematically shows the key 6 from FIG. 1 in front of a reading device 17 with a large receiving antenna 18.
