Description

Die Erfindung betrifft einen elektronisch aktivierbaren Sperrmechanismus für eine Schließeinrichtung mit einer Antenne zum Empfang von Signalen eines Transponders eines Datenträgers und zur Erzeugung von elektrischen, dem Transponder entsprechenden Signalen, mit einer Steuerelektronik zur Auswertung der Signale der Antenne und zur Ansteuerung eines Sperrriegels in Abhängigkeit von den Daten des Transponders und mit einer Signalerfassungseinrichtung zur Erfassung des Signals der Antenne und mit einer Datenerfassungseinrichtung zur Erfassung und Auswertung der Daten-Signale des Transponders, wobei die Signalerfassungseinrichtung und die Datenerfassungseinrichtung unabhängig voneinander aktivierbare Baugruppen aufweisen, dass die Baugruppen miteinander verbunden sind und dass die Baugruppe der Datenerfassungseinrichtung im Grundzustand inaktiv ist und durch ein Signal der Signalerfassungseinrichtung aktivierbar ist.The invention relates to an electronically activatable locking mechanism for a locking device with an antenna for receiving signals of a transponder of a data carrier and for generating electrical signals corresponding to the transponder, with an electronic control unit for evaluating the signals of the antenna and for controlling a locking bolt in dependence on the Data of the transponder and with a signal detection device for detecting the signal of the antenna and with a data acquisition device for detecting and evaluating the data signals of the transponder, wherein the signal detection device and the data acquisition device have independently activatable modules, that the modules are interconnected and that the module the data acquisition device is inactive in the ground state and can be activated by a signal of the signal detection device.

Solche Sperrmechanismen werden beispielsweise bei so genannten elektronischen Schließzylindern oder bei Schließanlagen für Kraftfahrzeuge eingesetzt. Der Transponder und der Datenträger dienen zum Nachweis einer Person zur Berechtigung der Ansteuerung des Sperrmechanismus. Befindet sich der Transponder im Empfangsbereich der Antenne, wird der Datenträger ausgelesen und von der Steuerelektronik die Berechtigung zur Aktivierung des Sperrmechanismus ermittelt. Eine ständige Bereitschaft der Steuerelektronik hat jedoch den Nachteil eines sehr hohen Stromverbrauchs. Ein hoher Stromverbrauch führt insbesondere bei batteriebetriebenen Schließeinrichtungen, wie elektronischen Schließzylindern, zu einer kurzen Lebensdauer der Batterie und damit zu einem hohen Wartungsaufwand des Sperrmechanismus.Such locking mechanisms are used for example in so-called electronic locking cylinders or locking systems for motor vehicles. The transponder and the data carrier serve as proof of a person to authorize the activation of the locking mechanism. If the transponder is located in the reception area of the antenna, the data carrier is read out and the authorization of the control electronics to activate the blocking mechanism determined. However, a constant readiness of the control electronics has the disadvantage of a very high power consumption. A high power consumption leads in particular with battery-operated locking devices, such as electronic locking cylinders, to a short life of the battery and thus to a high maintenance of the locking mechanism.

Daher ist aus der DE 198 32 203 A1 eine Schaltungsanordnung für eine Schließanlage eines Kraftfahrzeuges bekannt geworden, bei der zum Einschalten eines elektronisch betriebenen, Strom verbrauchenden Bauelementes ein Empfänger für eine bestimmte Zeit aktiviert wird. An dem Empfänger ist eine Antenne angeschlossen, so dass beide Bauteile gleichzeitig angesteuert werden. Dies hat einen hohen Stromverbrauch zur Folge.Therefore, from the DE 198 32 203 A1 a circuit arrangement for a locking system of a motor vehicle has become known, in which a receiver for a certain time is activated to switch on an electronically operated power-consuming component. An antenna is connected to the receiver so that both components are controlled simultaneously. This results in a high power consumption.

Zur Verringerung des Stromverbrauchs bei einem so genannten Bereitschaftsbetrieb ist es aus der EP 1 235 190 A1 beispielsweise bekannt, der Steuerelektronik einen kapazitiven Sensor vorzuschalten. Bei Annäherung einer Person an den Sperrmechanismus aktiviert der kapazitive Sensor die Steuerelektronik. Anschließend wird die Datenabfrage gestartet. Der kapazitive Sensor verursacht jedoch einen sehr hohen konstruktiven Aufbau des Sperrmechanismus. Weiterhin aktiviert der Sensor die Steuerelektronik bei jeder Annäherung einer Person, eines Tieres und gegebenenfalls eines Metallteils oder bei Regen, was zu einem hohen Stromverbrauch führt.To reduce the power consumption in a so-called standby mode, it is from the EP 1 235 190 A1 For example, known to precede the control electronics a capacitive sensor. When a person approaches the locking mechanism, the capacitive sensor activates the control electronics. Then the data query is started. However, the capacitive sensor causes a very high structural design of the locking mechanism. Furthermore, the sensor activates the control electronics with each approach of a person, an animal and possibly a metal part or in the rain, which leads to a high power consumption.

Weiterhin ist aus der DE 101 45 026 A1 ein Sperrmechanismus bekannt, bei dem eine zweite Antenne als Annäherungssensor vorgesehen ist. Der Annäherungssensor aktiviert die Datenabfrage. Diese zweite Antenne verursacht jedoch einen beträchtlichen baulichen Aufwand und hat einen großen Platzbedarf. Bedingt durch den hohen Platzbedarf lässt sich die zweite Antenne nur schwer in einem Schließzylinder anordnen.Furthermore, from the DE 101 45 026 A1 a locking mechanism is known in which a second antenna is provided as a proximity sensor. The proximity sensor activates the data query. However, this second antenna causes considerable structural complexity and has a large footprint. Due to the high space requirement the second antenna is difficult to arrange in a lock cylinder.

Der Erfindung liegt das Problem zugrunde, einen Sperrmechanismus der eingangs genannten Art so weiterzubilden, dass er einen möglichst geringen Stromverbrauch hat und ein hoher baulicher Aufwand weitgehend vermieden wird.The invention is based on the problem, a locking mechanism of the type mentioned in such a way that it has the lowest possible power consumption and high structural complexity is largely avoided.

Dieses Problem wird erfindungsgemäß gelöst, durch der Merkmale des Anspruchs 1.This problem is solved according to the invention by the features of claim 1.

Durch diese Gestaltung muss im Grundzustand ausschließlich die Signalerfassungseinrichtung zyklisch aktiv sein. Da die Signalerfassungseinrichtung keine Erfassung von Daten-Signalen des Transponders betreibt, erfordert diese einen besonders geringen Strombedarf. Die Signalerfassungseinrichtung erfasst erfindungsgemäß, ob sich überhaupt ein Transponder in der Nähe der Antenne befindet. Erst wenn irgendein Transponder erfasst ist, wird die Datenerfassungseinrichtung gestartet, die Daten aus dem Datenträger ausgelesen und die Berechtigung zum Ansteuern des Sperrmechanismus festgestellt. Weiterhin benötigt der erfindungsgemäße Sperrmechanismus keine weiteren Sensoren zum Start der Datenerfassungseinrichtung, da die Datenerfassungseinrichtung von der die Signale des Transponders empfangenden Signalerfassungseinrichtung aktiviert wird. Der erfindungsgemäße Sperrmechanismus ist daher besonders einfach aufgebaut und weist einen geringen Strombedarf auf. Eine ständige Empfangsbereitschaft der Antenne wird vermieden, wenn die Signalerfassungseinrichtung einen Impulsgeber und eine erste, für die Dauer eines Impulses ansteuerbare Schaltstufe aufweist und wenn die erste Schaltstufe die Antenne während des Impulses mit einer Stromquelle verbindet. Dies trägt zur weiteren Verringerung des Stromverbrauchs der Steuerelektronik bei.Due to this design, only the signal detection device must be cyclically active in the basic state. Since the signal detection device operates no detection of data signals of the transponder, this requires a particularly low power consumption. According to the invention, the signal detection device detects whether there is even a transponder in the vicinity of the antenna. Only when any transponder is detected, the data acquisition device is started, the data read from the disk and the authorization to control the locking mechanism detected. Furthermore, the locking mechanism according to the invention requires no further sensors for starting the data acquisition device, since the data acquisition device is activated by the signal detection device receiving the signals of the transponder. The locking mechanism according to the invention is therefore particularly simple and has a low power consumption. A constant readiness to receive the antenna is avoided if the signal detection means comprises a pulse generator and a first, for the duration of a pulse controllable switching stage and if the first switching stage, the antenna during the pulse with a Power source connects. This contributes to the further reduction of power consumption of the control electronics.

Eine schnelle Erfassung eines im Empfangsbereich der Antenne befindlichen Transponders bei gleichzeitig geringem Stromverbrauch des erfindungsgemäßen Sperrmechanismus lässt sich einfach erreichen, wenn der Impulsgeber Impulse mit einer an die Antennencharakteristik angepassten Dauer liefert. Zur schnellen Erfassung eines Transponders im Empfangsbereich genügen häufig vier Impulse in der Sekunde.A rapid detection of a transponder located in the receiving region of the antenna with simultaneously low power consumption of the locking mechanism according to the invention can be easily achieved if the pulse generator pulses with a matched to the antenna characteristic Duration delivers. For rapid detection of a transponder in the reception area, four pulses per second are often sufficient.

Die Datenerfassungseinrichtung lässt sich bei Empfang eines Signals über die Antenne gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach aktivieren, wenn die Datenerfassungseinrichtung eine dritte Schaltstufe zu ihrer Aktivierung hat und wenn die dritte Schaltstufe von der Signalerfassungseinrichtung ansteuerbar ist. Bei Ausbleiben eines Signals der Antenne verharrt die Datenerfassungseinrichtung im inaktiven Zustand und vermeidet daher unnötigen Stromverbrauch bei Bereitschaft ohne Signal der Antenne.The data acquisition device can be easily activated upon receipt of a signal via the antenna according to another advantageous development of the invention, when the data acquisition device has a third switching stage for their activation and when the third switching stage is controlled by the signal detection device. In the absence of a signal of the antenna, the data acquisition device remains in the inactive state and therefore avoids unnecessary power consumption in standby without a signal of the antenna.

Das Erfassen des Transponders erfordert gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders geringen Stromverbrauch, wenn die zweite Schaltstufe bis zu 100µs im aktiven Zustand verharrt.The detection of the transponder requires according to another advantageous embodiment of the invention, a particularly low power consumption when the second switching stage remains up to 100μs in the active state.

Zur weiteren Verringerung des Stromverbrauchs des erfindungsgemäßen Sperrmechanismus trägt es bei, wenn eine Datenerfassungseinrichtung mit der dritten Schaltstufe verbunden ist. Die Erkennung durch die Signalerfassungseinrichtung ob ein Signal vorliegt, benötigt wesentlich weniger elektrische Energie als die Erkennung, welche Daten vorliegen. Durch die Anordnung der Datenerfassungseinrichtung ausschließlich nach der dritten Schaltstufe lässt sich der Stromverbrauch für die Datenerfassungseinrichtung besonders gering halten.To further reduce the power consumption of the locking mechanism according to the invention, it contributes, when a data acquisition device is connected to the third switching stage. The detection by the signal detection means whether there is a signal requires much less electrical energy than the detection of which data is present. The arrangement of the data acquisition device exclusively after the third switching stage, the power consumption for the data acquisition device can be kept very low.

Der erfindungsgemäße Sperrmechanismus ist besonders kompakt aufgebaut, wenn die Signalerfassungseinrichtung und die Datenerfassungseinrichtung einen gemeinsamen Mikroprozessor aufweisen.The locking mechanism according to the invention is designed to be particularly compact when the signal detection device and the data acquisition device have a common microprocessor.

Zwischen der Steuerelektronik und einem Aktuator des Sperrriegels ist eine vierte Schaltstufe angeordnet. Die vierte Schaltstufe lässt sich einfach ansteuern, wenn die Datenerfassungseinrichtung die Signale des Transponders ausgewertet hat und den Sperrmechanismus freigibt. Ohne Freigabeberechtigung unterbleibt die Ansteuerung der vierten Schaltstufe, so dass der Sperrriegel stromlos in seiner den Schließzylinder blockierenden Stellung verharrt.Between the control electronics and an actuator of the locking bar, a fourth switching stage is arranged. The fourth switching stage can be easily controlled if the data acquisition device has evaluated the signals of the transponder and releases the locking mechanism. Without authorization to release the control of the fourth switching stage is omitted, so that the locking latch remains de-energized in its blocking the locking cylinder position.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt in

The invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in

Fig.2

Figur 1 zeigt schematisch eine Schnittdarstellung durch einen Schließzylinder 1 mit einem in einem Gehäuse 2 drehbaren Kern 3 und einem elektronisch aktivierbaren Sperrmechanismus 4 zur wahlweisen Blockierung oder Freigabe der Bewegung des Kerns 3. Der Sperrmechanismus 4 hat eine mit einem Aktuator 5 verbundene Steuerelektronik 6. Der Aktuator 5 dient zum Halten oder Freigeben der Bewegung eines in eine Ausnehmung 7 des Kerns 3 vorgespannten Sperrriegels 8. Die Steuerelektronik 6 ist mit einer Antenne 9 verbunden und wird von einer Batterie 10 als Stromquelle mit elektrischem Strom versorgt. Der Kern 3 weist einen Schließkanal 11 zur Aufnahme eines Schaftes eines Schlüssels 12 auf. Der Schlüssel 12 hat einen mit einem Transponder 13 verbundenen Datenträger 14. Wird der Schlüssel 12 in die Nähe der Antenne 9 bewegt, empfängt diese Signale des Transponders 13. Die Steuerelektronik 6 liest den Datenträger 14 aus und ermittelt aus diesen Daten eine Schließberechtigung des Schließzylinders 1. Damit wird in Abhängigkeit von den Daten des Datenträgers 14 der Aktuator 5 wahlweise angesteuert oder die Ansteuerung unterbleibt. FIG. 1 schematically shows a sectional view through a lock cylinder 1 with a rotatable in a housing 2 core 3 and an electronically activated locking mechanism 4 for selectively blocking or releasing the movement of the core 3. The locking mechanism 4 has an actuator connected to 5 control electronics 6. The actuator. 5 serves to hold or release the movement of a biased into a recess 7 of the core 3 locking bolt 8. The control electronics 6 is connected to an antenna 9 and is powered by a battery 10 as a power source with electrical power. The core 3 has a closing channel 11 for receiving a shank of a key 12. The key 12 has a data carrier 14 connected to a transponder 13. If the key 12 moves in the vicinity of the antenna 9, it receives signals of the transponder 13. The control electronics 6 reads the data carrier 14 and determines from these data a locking authorization of the lock cylinder 1 Thus, depending on the data of the data carrier 14, the actuator 5 is selectively activated or the control is omitted.

Figur 2 zeigt einen Schaltplan des Sperrmechanismus 4 aus Figur 1 mit dem Datenträger 14 und dem Transponderschwingkreis 13 des Schlüssels. Die Steuerelektronik 6 hat eine Signalerfassungseinrichtung 15 zum Empfang der Signale der Antenne 9 und eine Datenerfassungseinrichtung 16 zum Auslesen des Datenträgers 14 und zur Ermittlung der Schließberechtigung. Die Signalerfassungseinrichtung 15 und die Datenerfassungseinrichtung 16 haben einen gemeinsamen Mikroprozessor 17 und unabhängig voneinander aktivierbare Baugruppen. Eine Baugruppe der Signalerfassungseinrichtung 15 weist einen Impulsgeber 18 und eine erste Schaltstufe 19 auf. In Abhängigkeit von den Signalen des Impulsgebers 18 wird die erste Schaltstufe 19 angesteuert und die Antenne 9 mit der Batterie 10 verbunden. Hierdurch wird in der Antenne 9 ein magnetischer Impuls gebildet. Sofern sich ein Transponder 13 im Empfangsbereich der Antenne 9 befindet, ergeben sich in der Antenne 9 Rückwirkungen aufgrund des magnetischen Pulses. Durch Aktivierung der zweiten Schaltstufe 20 der Signalerfassungseinrichtung 15 wird die Batterie 10 mit dem Verstärker 21 verbunden. Damit werden die Rückwirkungen in der Antenne 9 erfasst und dem Mikroprozessor 17 zur Signalauswertung weitergeleitet. Der Mikroprozessor 17 erkennt den im Empfangsbereich der Antenne 9 vorhandenen Transponder 13 und aktiviert daraufhin die dritte Schaltstufe 25 und verbindet so die Datenerfassungseinrichtung 16 mit der Batterie 10. Ein Trägergenerator 28 bestromt die Antenne 9 periodisch. Die Antenne 9 sendet dadurch ein magnetisches Wechselfeld, das den Transponder 13 in ihrem Empfangsbereich mit Energie versorgt, und der Transponder 13 sendet daraufhin seine Daten aus. Diese werden aus dem Signal der Antenne von einem Demodulator 26 und einem Verstärker 27 erfasst und an den Mikroprozessor 17 zur Auswertung weitergeleitet. Der Mikroprozessor 17 ist mit einer vierten Schaltstufe 22 verbunden, welche den in Figur 1 dargestellten Aktor 5 ansteuert. FIG. 2 shows a circuit diagram of the locking mechanism 4 from FIG. 1 with the data carrier 14 and the transponder resonant circuit 13 of the key. The control electronics 6 has a signal detection device 15 for receiving the signals of the antenna 9 and a data acquisition device 16 for reading the data carrier 14 and for determining the locking authorization. The signal detection device 15 and the data acquisition device 16 have a common microprocessor 17 and independently activatable modules. An assembly of the signal detection device 15 has a pulse generator 18 and a first switching stage 19. In response to the signals of the pulse generator 18, the first switching stage 19 is driven and the antenna 9 is connected to the battery 10. As a result, a magnetic pulse is formed in the antenna 9. If a transponder 13 is located in the reception area of the antenna 9, reverberations due to the magnetic pulse result in the antenna 9. By activating the second switching stage 20 of the signal detection device 15, the battery 10 is connected to the amplifier 21. Thus, the repercussions are detected in the antenna 9 and forwarded to the microprocessor 17 for signal evaluation. The microprocessor 17 detects the present in the reception area of the antenna 9 transponder 13 and then activates the third Switching stage 25 and thus connects the data acquisition device 16 with the battery 10. A carrier generator 28 energizes the antenna 9 periodically. The antenna 9 thereby transmits an alternating magnetic field which supplies energy to the transponder 13 in its reception area, and the transponder 13 then transmits its data. These are detected from the signal of the antenna by a demodulator 26 and an amplifier 27 and forwarded to the microprocessor 17 for evaluation. The microprocessor 17 is connected to a fourth switching stage 22, which corresponds to the in FIG. 1 actuator 5 shown controls.

Bei Abwesenheit eines Transponders 13 von dem Empfangsbereich der Antenne 9 erhält in Abhängigkeit von den Signalen des Impulsgebers 18 die erste Schaltstufe einen periodischen Anregungsimpuls. Damit wird die Wicklung der Antenne 9 bestromt. Es bildet sich in der Antennennähe ein magnetisches Feld, welches wegen der Kürze des Impulses wieder zusammenbricht. Nach dem Impuls entsteht damit in der Antenne 9 keine periodische Spannungsänderung als Rückwirkung durch den Impuls, was zur Folge hat, dass die dritte Schaltstufe 25 nicht angesteuert wird und die Datenerfassung nicht eingeschaltet wird.In the absence of a transponder 13 from the receiving area of the antenna 9 receives in response to the signals of the pulse generator 18, the first switching stage a periodic excitation pulse. Thus, the winding of the antenna 9 is energized. A magnetic field forms close to the antenna, which collapses because of the short pulse. After the pulse thus arises in the antenna 9 no periodic voltage change as a reaction by the pulse, which has the consequence that the third switching stage 25 is not driven and the data acquisition is not turned on.

Befindet sich irgendein Transponder 13 mit seinem Schwingkreis im Empfangsbereich der Antenne 9, wird bei Aussendung des Impulses des Impulsgebers 18 ein Teil der vom Transponder 13 empfangenen magnetischen Energie in elektrische Energie induziert und an einen Resonanzkondensator 23 des Transponders weitergegeben. Durch die stoßförmige Anregung des Schwingkreises im Transponder 13 stellt sich nach dem Impuls eine abklingende, periodische Schwingung gemäß der Resonanzcharakteristik des Antennenkreises ein. Eine Transponderantenne 24 erzeugt im Rhythmus der Schwingung ein relativ schwaches magnetisches Feld. Die Antenne 9 empfängt das Feld und gibt es als Wechselspannungssignal an den Verstärker 21 der Signalerfassungseinrichtung 15 weiter. Der Mikroprozessor 17 steuert nach Auswertung der Impulsfolge die dritte Schaltstufe 25 für die Datenerfassungseinrichtung 16 an.If any transponder 13 with its resonant circuit is in the reception range of the antenna 9, when the pulse of the pulse generator 18 is emitted, part of the magnetic energy received by the transponder 13 is induced into electrical energy and transmitted to a resonant capacitor 23 of the transponder. Due to the pulse-shaped excitation of the resonant circuit in the transponder 13, a decaying, periodic oscillation arises in accordance with the resonance characteristic of the antenna circuit after the pulse. A transponder antenna 24 generates a relatively weak magnetic in rhythm with the vibration Field. The antenna 9 receives the field and passes it as an AC signal to the amplifier 21 of the signal detection means 15 on. The microprocessor 17 controls after evaluation of the pulse train, the third switching stage 25 for the data acquisition device 16 at.
