It is therefore important that several times per second the environment of the lock cylinder is queried for the presence of a transponder. In the prior art, it has therefore already been proposed to detect the approach of an object with a proximity switch.

Description

Die Erfindung betrifft eine Einrichtung zur Kommunikation mit einem Transponder, die bspw. als Schloss oder als Schließzylinder verkörpert sein kann.The invention relates to a device for communication with a transponder, which may be embodied, for example, as a lock or as a lock cylinder.

Die DE 19859 344 A1 beschreibt eine Kommunikationseinrichtung mit einem Sender und mit einer Empfängereinrichtung. Die Empfängereinrichtung besitzt zwei Antennen. Eine dieser Antennen soll ein Startsignal aussenden. Mit dem Startsignal wird an den Transponder Energie übertragen. Der Transponder korrespondiert dann mit der Empfangseinrichtung. Die Sendeenergie wird induktiv, also über eine magnetische Kopplung übertragen.The DE 19859 344 A1 describes a communication device with a transmitter and with a receiver device. The receiver device has two antennas. One of these antennas should emit a start signal. With the start signal energy is transferred to the transponder. The transponder then corresponds to the receiving device. The transmission energy is transmitted inductively, that is via a magnetic coupling.

Aus der US 2005/0204787 ist ein Hotelsafe bekannt, der über eine Funkverbindung schließtechnische Daten zwecks Abrechnung übertragen kann.From the US 2005/0204787 is a hotel safe known, which can transmit via a wireless connection locking data for the purpose of billing.

Die DE 100 45 631 A1 beschreibt einen Schließzylinder, der ein Gehäuse besitzt, in welchem sich ein elektrisch betätigbares Sperrglied und eine Antenne zum Empfang eines elektromagnetischen Signals zur Freigabe des Sperrelementes befindet. Die Antenne wirkt mit einer Sende-Empfangseinrichtung zusammen, welche von einer Steuereinrichtung in Intervallen von 5 - 500 ms bevorzugt zwei bis viermal pro Sekunde jeweils für kurze Zeit bestromt wird. Dabei baut die Antenne im Umfeld des Schließzylinders ein elektromagnetisches Wechselfeld auf, welches eine Frequenz aufweist, die der Arbeitsfrequenz des Transponders entspricht. Letztere liegt typischerweise bei 13,56 MHz oder 125 kHz. Befindet sich innerhalb dieses Erregerfeldes ein Transponder, so koppelt das elektromagnetische Wechselfeld induktiv mit der Antennenspule des Transponders. Dort wird eine Spannung induziert, die nach einer Gleichrichtung als Energieversorgung für den Transponder dient. Der Transponder besitzt einen Mikrochip, auf dem eine eindeutige Seriennummer und ggf. auch Daten gespeichert sind. Der Mikrochip erhält über die magnetisch eingekoppelte Wechselspannung Energie und sendet über seine Antennenspule die Seriennummer bzw. Daten. Diese werden von der Antennenspule der Sende-Empfangseinrichtung des Schließzylinders empfangen und von einer Auswerteeinrichtung ausgewertet. Besitzt der Transponder eine Seriennummer, die als schließberechtigt hinterlegt ist, bzw. wird nach Auswertung anderweitiger Daten von der Auswerteeinrichtung eine Schließberechtigung festgestellt, wird ein Sperr- oder Kopplungsglied des Schließzylinders betätigt, so dass das Schließglied vom Betätigungsglied betätigbar ist.The DE 100 45 631 A1 describes a lock cylinder having a housing in which an electrically actuable locking member and an antenna for receiving an electromagnetic signal for releasing the blocking element is located. The antenna cooperates with a transceiver, which is energized by a control device at intervals of 5 - 500 ms, preferably two to four times per second each for a short time. In this case, the antenna builds an electromagnetic alternating field in the vicinity of the lock cylinder, which has a frequency corresponding to the operating frequency of the transponder. The latter is typically 13.56 MHz or 125 kHz. If a transponder is located within this exciter field, then the electromagnetic alternating field inductively couples with the antenna coil of the transponder. There, a voltage is induced, which serves as a power supply for the transponder after a rectification. The transponder has a microchip on which a unique serial number and possibly also data are stored. The microchip receives energy via the magnetically coupled alternating voltage and transmits the serial number or data via its antenna coil. These are received by the antenna coil of the transceiver of the lock cylinder and evaluated by an evaluation device. If the transponder has a serial number which is stored as authorized to close, or if a closing authorization is determined by the evaluation device after evaluation of other data, a blocking or coupling element of the locking cylinder is actuated, so that the closing element can be actuated by the actuating element.

Derartige Schließzylinder sind üblicherweise batteriebetrieben. Bei der Konstruktion einer Kommunikationseinrichtung mit dem Schließzylinder und einem Transponder ist deshalb auf eine minimale Gesamtenergieaufnahme zu achten. Andererseits muss aber sichergestellt werden, dass der Schließzylinder jederzeit durch Annäherung eines Transponders entsperrt wird. Es ist also wichtig, dass mehrmals pro Sekunde das Umfeld des Schließzylinders nach dem Vorhandensein eines Transponders abgefragt wird. Im Stand der Technik hat man deshalb bereits vorgeschlagen, die Annäherung eines Gegenstandes mit einem Näherungsschalter zu detektieren. Nachteilhaft an der Verwendung eines Näherungsschalters ist aber dessen Sensibilität auf jegliche Art von Metallen, so dass die Sende-Empfangseinrichtung auch dann bereits aktiviert wird, wenn lediglich ein Metallteil oder sich die Hand eines Benutzers dem Schließzylinder nähert. Es kommt zu einer Vielzahl von unnötigen Sende-Empfangsversuchen, die eine erhebliche Energie der Batterie des Schließzylinders entziehen. Beispielsweise kann eine ungünstige Anordnung von Metallteilen im Bereich eines Schließzylinders bereits dazu führen, dass permanent oder auch bei jedem x-beliebigen Öffnen der Tür von der Rauminnenseite her eine Aktivierung der Sende-Empfangseinrichtung erfolgt.Such lock cylinders are usually battery operated. In the construction of a communication device with the lock cylinder and a transponder is therefore to pay attention to a minimum total energy consumption. On the other hand, it must be ensured that the lock cylinder is unlocked at any time by approaching a transponder. It is therefore important that several times per second the environment of the lock cylinder is queried for the presence of a transponder. In the prior art, it has therefore already been proposed to detect the approach of an object with a proximity switch. A disadvantage of the use of a proximity switch but is its sensitivity to any kind of metals, so that the transceiver is also already activated when only a metal part or a user's hand approaches the lock cylinder. There are a variety of unnecessary transmission-reception attempts, which withdraw a significant amount of energy from the battery of the lock cylinder. For example, an unfavorable arrangement of metal parts in the region of a lock cylinder can already lead to an activation of the transceiver device occurring permanently or also every time the door is opened arbitrarily from the interior side of the room.

Einen Schließzylinder mit Schlüssel, bei dem das Schließgeheimnis in einem Transponder steckt, beschreibt auch die DE 10 2005 019 170 A1 .A lock cylinder with a key, in which the locking secret is in a transponder, also describes the DE 10 2005 019 170 A1 ,

Des Weiteren sind Kraftfahrzeugtürgriffe bekannt, in denen eine Antenne und eine Sensoranordnung angeordnet ist. Bei der Sensoranordnung handelt es sich um einen kapazitiven Sensor, der die Annäherung einer Person feststellt. Wird die Annäherung einer Person festgestellt, so wird eine Sende-Empfangseinrichtung in Betrieb genommen, um in der oben beschriebenen Weise mit einem Transponder zu kommunizieren.Furthermore, motor vehicle door handles are known in which an antenna and a sensor arrangement is arranged. The sensor assembly is a capacitive sensor that detects the approach of a person. If the approach of a person is detected, then a transceiver is put into operation to communicate with a transponder in the manner described above.

Der Erfindung liegt die Aufgabe zugrunde, den elektrischen Energieverbrauch einer Kommunikationseinrichtung zu reduzieren.The invention has for its object to reduce the electrical energy consumption of a communication device.

Gelöst wird die Aufgabe durch die im Anspruch 1 angegebene Kommunikationseinrichtung.The object is achieved by the specified in claim 1 communication device.

Bei der erfindungsgemäßen Kommunikationseinrichtung bildet die zweite Antenne eine induktive Sensoranordnung, die, von der Steuereinrichtung gesteuert, in vorgegebenen Intervallen kurzzeitig ein elektromagnetisches Sensorfeld aufbaut, dessen Frequenz im Wesentlichen der Arbeitsfrequenz der ersten Antenne und damit der Resonanzfrequenz der Antenne des Transponders entspricht. Beim Annähern des Transponders wird das Sensorfeld vom Schwingkreis des Transponders beeinflusst. Die Sende-Empfangseinrichtung sendet erst dann das Aktivierungssignals ab, wenn die Beeinflussung des Sensorfeldes einen vorgegebenen Schwellwert über- bzw. unterschreitet. Die das elektromagnetische Sensorfeld erzeugende Antenne bildet einen Schwingkreis, dessen Frequenz im Wesentlichen dieselbe ist, mit der die Sende-Empfangseinrichtung arbeitet. Der induktive Sensor ist von einem energiesparenden Typ. Er kann einen separaten Hochfrequenz-Schaltkreis enthalten. Die periodische Ansteuerung des Sensors und die Auswertung des Ausgangssignals des Sensors erfolgt durch einen Mikroprozessor. Die Detektion eines Transponders wird durch einen Schwellwertvergleich realisiert. Die Sende-Empfangseinrichtung zum Aussenden des Aktivierungssignals wird nur dann eingeschaltet, wenn sicher die Annäherung eines Transponders detektiert wurde. Die Energie zum Betrieb der induktiven Sensoranordnung ist erheblich geringer als die Energie, die erforderlich ist, um mittels der Sende-Empfangseinrichtung ein Aktivierungssignal auszusenden. Die induktive Sensoranordnung arbeitet dabei mit dem Schwingkreis des Transponders zusammen. Es werden somit nur solche Transponder detektiert, deren Resonanzfrequenz nahe bei der Arbeitsfrequenz der induktiven Sensoranordnung liegt. Ein Annähern von Personen oder Metallen wird somit nicht detektiert. Dadurch kann auch ein fehlerhaftes Einschalten der Sende-Empfangseinrichtung minimiert werden. Auch dies führt zu einer Einsparung von elektrischer Energie. Das Sensorfeld wird bevorzugt von einer an einen Frequenzgenerator gekoppelten Antenne erzeugt. Bei der Antenne kann es sich um eine Induktionsspule handeln. Die Antennenspule wird vom Frequenzgenerator in Intervallen, die im Bereich zwischen 5 - 500 msec liegen können, kurzzeitig mit einer Wechselspannung beaufschlagt. Die Beaufschlagung erfolgt über einige Hundert Schwingungsperioden. Beträgt de Arbeitsfrequenz des Transponders 13,56 MHz, so haben die Pulse eine Dauer von 10 - 50 µs. Beträgt die Arbeitsfrequenz des Transponders 125 KHz, so sind die Pulse entsprechend länger und liegen zwischen 1 und 5 ms. Die Sendeleistung dieser Antenne ist erheblich geringer als die Sendeleistung der Antenne, die von der Sende-Empfangseinrichtung mit Spannung versorgt wird. An der Antenne der induk-tiven Sensoranordnung wird die Antennenspannung abgegriffen. Dies erfolgt bevorzugt hochohmig. Die Steuereinrichtung besitzt einen Analog-Digitalwandler, der die abgegriffene Antennenspannung in einen Digitalwert umwandelt. Die Steuereinrichtung besitzt darüber hinaus einen Schwellwert-Vergleicher, welcher als Softwaremodul ausgebildet sein kann. Dieser Schwellwert-Vergleicher vergleicht die digitalisierte Antennenspannung mit einem oberen und einem unteren Schwellwert. Der obere und der untere Schwellwert bilden ein Fenster aus. Liegt die Antennenspannung innerhalb des Fensters, bedeutet dies, dass kein Transponder in der Nähe der Antenne ist. Liegt die Antennenspannung außerhalb dieses Fensters, also oberhalb des oberen Schwellwertes oder unterhalb des unteren Schwellwertes, so ist davon auszugehen, dass sich ein Transponder im Lesebereich der Kommunikationseinrichtung befindet. In diesem Falle wird die Sende-Empfangseinrichtung in Betrieb genommen. Sie sendet das Aktivierungssignal in Form eines elektromagnetischen Wechselfeldes und empfängt vom Transponder die zurückgesandten Daten. Besitzt der Transponder Schließberechtigung, so wird ein entsprechendes Ausgangssignal bereitgestellt, mit dem ein Sperrglied oder ein Kupplungsglied betätigt werden kann. Die das elektromagnetische Sensorfeld erzeugende Antenne wird bevorzugt mit einer Frequenz betrieben, die im Bereich der Arbeitsfrequenz des Transponders liegt. Sie kann etwas größer oder etwas kleiner sein. Auf Grund von herstellungstechnischen Toleranzen liegen die Frequenzen der zu detektierenden Transponder nicht immer exakt bei 13,56 MHz. Die Arbeitsfrequenzen der Transponder dieser Klasse können bis zu 18 MHz betragen. Insofern reicht es, wenn die Frequenz des elektromagnetischen Wechselfeldes der Sensoreinrichtung auch in diesem Toleranzfeld liegt. Die Frequenz des Sensorfeldes muss auch nicht stabilisiert sein. Es ist nicht nur zulässig, wenn die Frequenz des Sensorfeldes um die Arbeitsfrequenz des Transponders bzw. um die Arbeitsfrequenz der Sende-Empfangseinrichtung schwankt bzw. driftet. Dies kann sogar vorteilhaft sein. Der Frequenzgenerator kann ein L-C-Schwingkreis sein. Bevorzugt wird der Frequenzgenerator aber von einem R-C-Glied ausgebildet. Die Kommunikationseinrichtung bezitzt zwei Antennen. Eine erste Antenne ist der Sende-Empfangeinrichtung zugeordnet und eine zweite Antenne der induktiven Sensoranordnung. Da beide Antennen auf nur wenig voneinander verschiedenen Frequenzen arbeiten, liegt ein stark gekoppeltes Spulensystem vor. Trotz der parasitären Effekte der jeweils anderen Spule und der daran angeschlossenen Bauelemente, besitzt jede Spule aber die gewünschten Eigenschaften in Bezug auf Resonanzfrequenz und Feldstärke. Die Sendeleistung der induktiven Sensoranordnung braucht höchstens 10% der Sendeleistung der Sendeempfangseinrichtung zur Erzeugung des Aktivierungssignals betragen. Mit der erfindungsgemäß ausgestalteten Kommunikationseinrichtung lassen sich gemittelte Versorgungsstromstärken in der passiven Phase der Kommunikationseinrichtung von unter 10 Mikroampere realisieren. Zudem wird mit der erfindungsgemäßen Dimensionierung der Sensoranordnung die Anzahl der vergeblichen Sende- und Empfangsversuche mit einem Transponder erheblich reduziert. Diese Stromstärken von 100 Milliampere erfordernden Datenaustausch-Kommunikationsversuche finden in der Regel nur dann statt, wenn tatsächlich ein Transponder in unmittelbarer Nähe vor der Antennenanordnung liegt. Diese, insgesamt geringe Stromaufnahme führt zu einer längeren Batterielebensdauer. Es ist ferner von Vorteil, wenn die Sensorspule eine gewickelte Luftspule ist und etwa gleich viele Windungen aufweist, wie die von einer spiralförmigen Leiterbahn ausgebildete Lesespule. Letztere kann rückwärtig der Sensorspule in einem Gehäuse angeordnet sein. Vor der gewickelten Luftspule befindet sich dann die Detektionszone. Die beiden Antennenspulen können zur Optimierung der magnetischen Kopplung koaxial zueinander angeordnet sein und einen gleichen Durchmesser aufweisen. Es reicht grundsätzlich aber aus, wenn die beiden Spulen sich lediglich bereichsweise magnetisch gekoppelt sind.In the case of the communication device according to the invention, the second antenna forms an inductive sensor arrangement which, controlled by the control device, temporarily builds up an electromagnetic sensor field at predetermined intervals, the frequency of which essentially corresponds to the operating frequency of the first antenna and thus to the resonance frequency of the antenna of the transponder. When approaching the transponder, the sensor field is influenced by the resonant circuit of the transponder. The transmitting-receiving device does not transmit the activation signal until the influencing of the sensor field exceeds or falls below a predetermined threshold value. The electromagnetic sensor field generating antenna forms a resonant circuit whose frequency is substantially the same with which the transceiver operates. The inductive sensor is of an energy-saving type. It can contain a separate high-frequency circuit. The periodic control of the sensor and the evaluation of the output signal of the sensor takes place through a microprocessor. The detection of a transponder is realized by a threshold value comparison. The transceiver for transmitting the activation signal is only turned on when the approach of a transponder has been detected. The energy for operating the inductive sensor arrangement is considerably lower than the energy required to emit an activation signal by means of the transceiver. The inductive sensor arrangement works together with the resonant circuit of the transponder. Thus, only those transponders are detected whose resonant frequency is close to the operating frequency of the inductive sensor arrangement. An approach of persons or metals is thus not detected. As a result, an erroneous switching on of the transceiver device can be minimized. This also leads to a saving of electrical energy. The sensor field is preferably generated by an antenna coupled to a frequency generator. The antenna may be an induction coil. The antenna coil is acted upon by the frequency generator at intervals, which may be in the range between 5 - 500 msec, for a short time with an alternating voltage. The admission takes place over several hundred oscillation periods. If the working frequency of the transponder is 13.56 MHz, then the pulses have a duration of 10 - 50 μs. If the operating frequency of the transponder is 125 KHz, the pulses are correspondingly longer and lie between 1 and 5 ms. The transmission power of this antenna is considerably lower than the transmission power of the antenna, which is supplied by the transceiver with voltage. At the antenna of the inductive Sensor arrangement, the antenna voltage is tapped. This is preferably done with high impedance. The control device has an analog-to-digital converter, which converts the tapped antenna voltage into a digital value. The control device also has a threshold comparator, which can be designed as a software module. This threshold comparator compares the digitized antenna voltage with an upper and a lower threshold. The upper and lower thresholds form a window. If the antenna voltage lies within the window, this means that there is no transponder near the antenna. If the antenna voltage lies outside this window, ie above the upper threshold value or below the lower threshold value, then it can be assumed that a transponder is located in the reading area of the communication device. In this case, the transceiver is put into operation. It sends the activation signal in the form of an alternating electromagnetic field and receives the returned data from the transponder. If the transponder has locking authorization, a corresponding output signal is provided with which a blocking member or a coupling member can be actuated. The electromagnetic sensor field generating antenna is preferably operated at a frequency which is in the range of the operating frequency of the transponder. It can be a bit bigger or smaller. Due to manufacturing tolerances, the frequencies of the transponder to be detected are not always exactly at 13.56 MHz. The operating frequencies of the transponders of this class can be up to 18 MHz. In this respect, it is sufficient if the frequency of the electromagnetic alternating field of the sensor device is also in this tolerance field. The frequency of the sensor field also does not have to be stabilized. It is not only permissible if the frequency of the sensor field fluctuates or drifts about the operating frequency of the transponder or about the operating frequency of the transceiver. This can even be beneficial. The frequency generator may be an LC resonant circuit. However, the frequency generator is preferred by an RC element educated. The communication device has two antennas. A first antenna is associated with the transceiver and a second antenna of the inductive sensor array. Since both antennas operate at frequencies that are only slightly different from each other, there is a strongly coupled coil system. Despite the parasitic effects of the other coil and the components connected to it, each coil has the desired properties in terms of resonance frequency and field strength. The transmission power of the inductive sensor arrangement needs to be at most 10% of the transmission power of the transceiver device for generating the activation signal. With the inventively designed communication device can average supply currents in the passive phase of the communication device of less than 10 microamps realize. In addition, with the inventive dimensioning of the sensor arrangement, the number of futile transmitting and receiving attempts with a transponder is considerably reduced. These currents of 100 milliamps requiring data exchange communication attempts usually take place only when a transponder is actually in close proximity to the antenna array. This, overall low power consumption leads to a longer battery life. It is also advantageous if the sensor coil is a wound air-core coil and has approximately the same number of turns as the read coil formed by a spiral-shaped conductor track. The latter can be arranged at the rear of the sensor coil in a housing. The detection zone is then located in front of the wound air-core coil. The two antenna coils can be arranged coaxially with each other to optimize the magnetic coupling and have a same diameter. It is basically sufficient, however, if the two coils are only partially magnetically coupled.

Ein Ausführungsbeispiel wird nachfolgend anhand beigefügter Zeichnungen erläutert. Es zeigen:

Fig.

grobschematisch einen Schließzylinder mit einer derartigen Komm unikationseinrichtung.
An embodiment will be explained below with reference to accompanying drawings. Show it:
FIG.
1 is a block diagram of the communication device, and
Fig. 2
roughly schematically a lock cylinder with such a comm Unikationseinrichtung.

Der in Fig. 2 dargestellte Schießzylinder besitzt ein Zylindergehäuse mit einer Gehäusebohrung, in welcher ein Zylinderkern 22 steckt. Der Zylinderkern 22 kann mit einer Handhabe, beispielsweise einem Schlüssel betätigt werden. Der Zylinderkern 22 kann darüber hinaus auch einen Drehknauf besitzen. Der Zylinderkern 22 ist mit einem Schließglied 21 gekoppelt. Mit dem Schließglied 21 kann ein Schließmechanismus eines Schlosses betätigt werden. Der Schließzylinder 20 ist bevorzugt ein Normschließzylinder und lässt sich in Türen einbauen. Innerhalb des Schließzylinders oder in einem Knauf befindet sich auch eine Batterie zur Stromversorgung.The in Fig. 2 shown shooting cylinder has a cylinder housing with a housing bore in which a cylinder core 22 is inserted. The cylinder core 22 can be operated with a handle, such as a key. The cylinder core 22 may also have a knob beyond. The cylinder core 22 is coupled to a closing member 21. With the closing member 21, a closing mechanism of a lock can be actuated. The lock cylinder 20 is preferably a standard lock cylinder and can be installed in doors. Within the lock cylinder or in a knob is also a battery for power supply.

Innerhalb des Flanschabschnittes des Schließzylinders 20 befindet sich ein mit der Bezugsziffer 23 angedeutetes Sperrglied, welches die Drehbarkeit des Zylinderkerns 22 sperren kann. Das Sperrglied 23 ist elektrisch betätigbar. Bei einer elektrischen Betätigung des Sperrgliedes 23 wird die Drehbarkeit des Zylinderkernes 22 entsperrt, so dass das Schließglied 21 von einer Handhabe betätigt werden kann.Within the flange portion of the lock cylinder 20 is an indicated by the reference numeral 23 locking member which can lock the rotation of the cylinder core 22. The locking member 23 is electrically actuated. In an electrical actuation of the locking member 23, the rotatability of the cylinder core 22 is unlocked, so that the closing member 21 can be actuated by a handle.

Alternativ dazu kann das Betätigungsglied 22 aber auch über ein Kupplungsglied mit dem Schließglied 21 gekuppelt sein. Im nicht-betätigten Zustand des elektrischen Kupplungsgliedes ist dann das Betätigungsglied nicht mit dem Schließglied gekuppelt. Erst bei elektrischer Betätigung des Kupplungsgliedes besteht eine drehfeste Verbindung zwischen Schließglied 21 und Betätigungsglied 22.Alternatively, the actuator 22 may also be coupled via a coupling member with the closing member 21. In the non-actuated state of the electric coupling member then the actuator is not coupled to the closing member. Only upon electrical actuation of the coupling member is there a rotationally fixed connection between closing member 21 and actuator 22nd

Das elektrische Signal zum Betätigen des Sperrgliedes oder des Kupplungsgliedes liefert eine Kommunikationseinrichtung, wie sie beispielsweise in der Figur 1 dargestellt ist. Mit der Bezugsziffer 11 ist dort der Schaltausgang dargestellt, der mit dem Sperr- oder Kupplungsglied verbunden ist. Die Bezugsziffer 10 deutet die Betriebsspannungsversorgung einer Steuereinrichtung 1 an. Bei der Steuereinrichtung 1 kann es sich um einen Mikrocontroller handeln. Innerhalb des Mikrocontrollers befinden sich eine Auswerteeinrichtung 4, ein Zeitgeber 19, ein Analogdigitalwandler 8 und ein Komparator 9. Die Kommunikationseinrichtung besitzt darüber hinaus eine Sende-Empfangseinrichtung 2, an der eine Antenne 3 angeschlossen ist. Des Weiteren besitzt die Kommunikationseinrichtung eine induktive Sensorschaltung 6, die ebenfalls mit einer Antenne 7 verbunden ist. Die Antenne 3 und die Sensorantenne 7 können von Spulen ausgebildet sein.The electrical signal for actuating the locking member or the coupling member provides a communication device, as shown for example in the FIG. 1 is shown. With the reference numeral 11, the switching output is shown there, which is connected to the locking or coupling member. The reference numeral 10 indicates the operating voltage supply to a control device 1. The control device 1 may be a microcontroller. Within the microcontroller are an evaluation device 4, a timer 19, an analog-digital converter 8 and a comparator 9. The communication device also has a transceiver 2, to which an antenna 3 is connected. Furthermore, the communication device has an inductive sensor circuit 6, which is likewise connected to an antenna 7. The antenna 3 and the sensor antenna 7 may be formed by coils.

Die Kommunikationseinrichtung kommuniziert mit einem Transponder 5. Der Transponder 5 kann in der Raide eines Schlüssels oder in einem Gehäuse in Form einer Münze angeordnet sein. Der Transponder 5 besitzt eine Transponderantenne 12, die mit einer Transponderschaltung 13 in Form eines Mikrochips verbunden ist. In der Transponderschaltung 13 ist eine Seriennummer gespeichert. Gegebenenfalls sind in der Transponderschaltung 13 auch weitere Daten gespeichert. Die Energieversorgung des Transponders 5 erfolgt durch induktive Ankopplung der Transponderantenne 12 an ein elektromagnetisches Wechselfeld von 13,56 MHz. Die in der Transponderantenne 12 eingekoppelte Wechselspannung wird gleichgerichtet und liefert die Betriebsspannung für die Transponderschaltung 13. Sobald diese mit ausreichender Energie versorgt ist, sendet sie über die Transponderantenne 12 auf der Trägerfrequenz 13,56 MHz Daten und insbesondere die eindeutige Seriennummer.The communication device communicates with a transponder 5. The transponder 5 may be arranged in the shape of a key or in a housing in the form of a coin. The transponder 5 has a transponder antenna 12, which is connected to a transponder circuit 13 in the form of a microchip. In the transponder circuit 13, a serial number is stored. Optionally, further data are stored in the transponder circuit 13. The energy supply of the transponder 5 is effected by inductive coupling of the transponder antenna 12 to an electromagnetic alternating field of 13.56 MHz. The coupled in the transponder antenna 12 AC voltage is rectified and provides the operating voltage for the transponder circuit 13. Once this is supplied with sufficient energy, it sends via the transponder antenna 12 on the carrier frequency 13.56 MHz data and in particular the unique serial number.

Das zuvor erwähnte elektromagnetische Wechselfeld zur Aktivierung des Transponders 5 wird von der Sende-Empfangseinrichtung 2 über die Antenne 3 erzeugt. Hierzu erhält die Sende-Empfangseinrichtung 2 über die mit der Bezugsziffer 14 gezeichnete Leitung ein Aktivierungssignal. Das Datensignal 15 wird von einer von der Sende-Emfangseinrichtung ausgebildeten Auswerteeinrichtung 4 ausgewertet. Besitzt der Transponder und insbesondere dessen eindeutige Seriennummer eine Schließberechtigung, so wird über den Schaltausgang 11 das Schaltsignal abgegeben.The aforementioned electromagnetic alternating field for activating the transponder 5 is transmitted by the transceiver 2 via the antenna 3 generated. For this purpose, the transceiver 2 receives an activation signal via the line indicated by the reference numeral 14. The data signal 15 is evaluated by an evaluation device 4 formed by the transmitting-receiving device. If the transponder and in particular its unique serial number has a locking authorization, the switching signal is output via the switching output 11.

Um das Aktivierungssignal 14 nur dann abzugeben, wenn mit hoher Wahrscheinlichkeit auch der Transponder im Empfangsbereich der Antenne 3 liegt, ist die Sensorschaltung 6 mit zugehöriger Sensorantenne 7 vorgesehen. Der von der Steuereinrichtung 1 ausgebildete Zeitgeber 19 liefert in Intervallen etwa zwei bis viermal pro Sekunde jeweils für kurze Zeiten (ca. 10 - 50 µs) eine Versorgungsspannung 16 für die Sensorschaltung 6. Die Versorgungsspannung 16 so lange geliefert, dass etwa 100 - 500 Amplituden gesendet werden. Die Amplitude liegt bei etwa 3 bis 10 V (Spitze - Spitze).In order to deliver the activation signal 14 only when the transponder is also located in the reception range of the antenna 3 with high probability, the sensor circuit 6 with associated sensor antenna 7 is provided. The timer 19 formed by the control device 1 supplies a supply voltage 16 for the sensor circuit 6 at intervals of approximately two to four times per second for short times (approximately 10 to 50 μs). The supply voltage 16 is supplied so long that approximately 100 to 500 amplitudes are produced be sent. The amplitude is about 3 to 10 V (peak to peak).

Die Sensorschaltung 6 besitzt einen Frequenzgenerator 18, der von einem R-C-Glied ausgebildet ist. Über ein oder mehrere Koppelkondensatoren und ein oder mehrere Koppelwiderstände wird die vom Frequenzgenerator 18 erzeugte Wechselspannung in die Sensorantenne 7 eingekoppelt. Die Frequenz der vom Frequenzgenerator 18 erzeugte Sensorfrequenz liegt im Wesentlichen auf der Arbeitsfrequenz des Transponders. Sie kann geringfügig oberhalb der Arbeitsfrequenz oder unterhalb der Arbeitsfrequenz des Transponders liegen. Wesentlich ist jedoch, dass eine Resonanzkopplung mit der Antenne 3 der Sende-Empfangseinrichtung 2 stattfindet. Dies führt zu einer gewollten Abschwächung der Detektionsleistung der Sensoranordnung und dazu, dass der Detektionsbereich auf den Bereich unmittelbar vor der Antennenanordnung beschränkt wird.The sensor circuit 6 has a frequency generator 18 which is formed by an RC element. About one or more coupling capacitors and one or more coupling resistors generated by the frequency generator 18 AC voltage is coupled into the sensor antenna 7. The frequency of the sensor frequency generated by the frequency generator 18 is substantially at the operating frequency of the transponder. It may be slightly above the working frequency or below the operating frequency of the transponder. It is essential, however, that a resonance coupling with the antenna 3 of the transceiver 2 takes place. This leads to a deliberate weakening of the detection performance of the sensor arrangement and to the fact that the detection area is limited to the area immediately in front of the antenna arrangement.

Befindet sich kein Transponder in der Nähe, so liegt die Antennenspannung in einem, von einem unteren und einem oberen Schwellwert gebildeten Fenster.If there is no transponder in the vicinity, the antenna voltage lies in a window formed by a lower and an upper threshold value.

Über einen hochohmigen Widerstand 24 wird die Antennenspannung der Sensorantenne 7 ausgekoppelt und mit einer AM-Demodulationsstufe gleichgerichtet. Die Antennenspannung 17 wird in einem Analog-Digitalwandler 8 in einen Digitalwert umgewandelt. Der Digitalwert entspricht der Amplitude der Sensorantenne 7.Via a high-impedance resistor 24, the antenna voltage of the sensor antenna 7 is coupled out and rectified with an AM demodulation stage. The antenna voltage 17 is converted into a digital value in an analog-to-digital converter 8. The digital value corresponds to the amplitude of the sensor antenna 7.

Mit der Bezugsziffer 9 ist ein Komparator bezeichnet, der im Mikrokontroller aber auch von einem Software-Modul ausgebildet sein kann. Im Komparator 9 wird das digitale Ausgangssignal des Analog-Digitalwandlers 8 mit einem abgespeicherten unteren und einem abgespeicherten oberen Schwellwert verglichen. Liegt der Digitalwert innerhalb des von den beiden Schwellwerten definierten Fensters, befindet sich kein Transponder im Empfangsbereich der Kommunikationseinrichtung.The reference numeral 9 denotes a comparator, which may be formed in the microcontroller but also by a software module. In the comparator 9, the digital output signal of the analog-to-digital converter 8 is compared with a stored lower and a stored upper threshold value. If the digital value lies within the window defined by the two threshold values, no transponder is located in the receiving area of the communication device.

Wird ein Transponder 5 in den Empfangsbereich der Kommunikationseinrichtung gebracht, also in den Wirkbereich der induktiven Sensoranordnung 6, 7, so wird dadurch das elektromagnetische Wechselfeld der induktiven Sensoranordnung 6, 7 beeinflusst. Wegen der Quasi-Resonanz kann es sich um eine Felddämpfung oder um eine Feldverstärkung handeln. Eine Felddämpfung führt zu einer Verminderung der Amplitude der Sensorantenne 7. Eine Feldverstärkung führt zu einer Erhöhung dieser Amplitude. Es sind in der Regel die geometrischen Eigenschaften der angenäherten Transponder, die dafür verantwortlich sind, ob es sich um eine Spannungsreduktion oder eine Spannungserhöhung handelt. Relevant ist aber die Resonanzankopplung, die verhindert, dass das bloße Annähern von Metallteilen oder der Hand eines Benutzers zu keiner signifikanten Änderung der Amplitude führt. Der aus der Antennenspannung 17 gewonnene Digitalwert muss also außerhalb eines Fensters liegen, um das Ausgangssignal abzugeben. Überschreitet der vom Digitalwandler 8 gewonnene Digitalwert den oberen Schwellwert, oder unterschreitet er den unteren Schwellwert, so gibt der Komparator 9 ein Ausgangssignal ab, welches die Abgabe eines Aktivierungssignals 14 von der Steuereinrichtung 1 und der Empfangsein-richtung 2 zur Folge hat. Erst jetzt baut die Sende-Empfangseinrichtung 2 mit Hilfe der Antenne 3 das elektromagnetische Wechselfeld auf der Arbeitsfrequenz des Transponders 5 auf, um induktiv mit der Antenne 12 des Transponders 5 zu koppeln und die Transponderschaltung 3 dazu anzuregen, in der oben beschriebenen Weise Daten und insbesondere die Seriennummer zu senden. Der Datenaustausch dauert ca. 50 - 100 ms. Die Belastung ist also mehr als zehnmal so hoch, wie die Belastung bei der Absendung des Detektionssignals.If a transponder 5 is brought into the reception area of the communication device, ie into the effective range of the inductive sensor arrangement 6, 7, the alternating electromagnetic field of the inductive sensor arrangement 6, 7 is thereby influenced. Because of the quasi-resonance, it may be a field attenuation or a field enhancement. A field attenuation leads to a reduction in the amplitude of the sensor antenna 7. Field amplification leads to an increase in this amplitude. It is usually the geometric properties of the approximated transponder that are responsible for whether it is a voltage reduction or a voltage increase. What is relevant, however, is the resonance coupling, which prevents the mere approach of metal parts or the hand of a user from leading to any significant change in the amplitude. The digital value obtained from the antenna voltage 17 must therefore lie outside a window, to deliver the output signal. Exceeds the digital value obtained from the digital converter 8, the upper threshold, or below the lower threshold, the comparator 9 outputs an output signal, which has the output of an activation signal 14 from the control device 1 and the Empfangsein-direction 2 result. Only now builds the transceiver 2 by means of the antenna 3, the electromagnetic alternating field on the operating frequency of the transponder 5 to inductively couple with the antenna 12 of the transponder 5 and the transponder circuit 3 to stimulate in the manner described above, data and in particular to send the serial number. The data exchange takes approx. 50 - 100 ms. The load is thus more than ten times as high as the load when sending the detection signal.

In einem nicht dargestellten Ausführungsbeispiel kann die induktive Sensorschaltung selbst aber auch einen Schwingkreis aufweisen. Es kann sich dabei um einen selbstanschwingenden Schwingkreis handeln, der durch Annähern des Schwingkreises 12 des Transponders 5 gedämpft, verstärkt oder verstimmt wird oder anfängt zu schwingen oder aufhört zu schwingen. Wird der Schwingkreis der Sensorschaltung 6 verstimmt, so kann das Sensorausgangssignal 17 anstelle eines Amplitudenwertes auch ein Frequenzwert sein, welcher in einen Digitalwert umgewandelt wird und dann mit Schwellwerten verglichen wird.In an embodiment not shown, the inductive sensor circuit itself but also have a resonant circuit. It may be a self-oscillating resonant circuit that is attenuated, amplified or detuned by approaching the resonant circuit 12 of the transponder 5 or begins to oscillate or stop oscillating. If the resonant circuit of the sensor circuit 6 is detuned, then instead of an amplitude value, the sensor output signal 17 can also be a frequency value which is converted into a digital value and then compared with threshold values.

Anstelle einer digitalen Bearbeitung des Ausgangssignals 17 des induktiven Sensors 6 kann aber auch eine Analogschaltung festgelegt werden.Instead of a digital processing of the output signal 17 of the inductive sensor 6 but also an analog circuit can be defined.

Die Versorgungsspannung des induktiven Sensors 6, 7 wird auch bei den zuvor nur erwähnten Ausführungsbeispielen periodisch von einem Mikroprozessor ein- und ausgeschaltet. Nach dem Einschalten der Versorgungsspannung beginnt ein Frequenzgenerator 18 mit einer Frequenzerzeugung, wobei die erfolgte Frequenz nahe bei der Arbeitsfrequenz des Transpondersystems liegt. An der Antenne des induktiven Sensors entsteht ein elektromagnetisches Wechselfeld. Dieses elektromagnetische Wechselfeld wird mit einem AM-Demodulator gleichgerichtet. Das gleichgerichtete Signal bildet das Ausgangssignal des induktiven Sensors. Ist kein Transponder in der Reichweite der Antenne, so stellt sich nach einer bestimmten Einschwingdauer von wenigen hundert Perioden ein bestimmter Spannungspegel als Ausgangsspannung ein. Diese Ausgangsspannung entspricht bei nicht im Feld befindlichem Transponder dem Ruhezustand. Bei sich im Feld befindlichen Transponder verändert sich der Spannungspegel des induktiven Sensors. Ab einem bestimmten Schwellwert kann sicher angenommen werden, dass sich ein Transponder ins Feld des induktiven Sensors genähert hat. Erst dann wird die eigentliche Kommunikation mit dem Transponder eingeschaltet.The supply voltage of the inductive sensor 6, 7 is also periodically switched on and off in the previously mentioned embodiments by a microprocessor. After switching on the supply voltage starts a frequency generator 18 with a frequency generation, which took place Frequency is close to the working frequency of the transponder system. An electromagnetic alternating field is created at the antenna of the inductive sensor. This alternating electromagnetic field is rectified with an AM demodulator. The rectified signal forms the output signal of the inductive sensor. If no transponder is within range of the antenna, then after a certain settling time of a few hundred periods, a certain voltage level arises as the output voltage. This output voltage corresponds to the idle state when the transponder is not in the field. When the transponder is in the field, the voltage level of the inductive sensor changes. From a certain threshold, it can be safely assumed that a transponder has approached the field of the inductive sensor. Only then is the actual communication with the transponder switched on.

Die von der Sensorantenne 7 erzeugten Feldstärken sind erheblich geringer, als die von der Antenne 3 aufgebauten Feldstärken.The field strengths generated by the sensor antenna 7 are considerably lower than the field strengths built up by the antenna 3.
