Definitions
- the invention relates to a lock according to the preamble of claim 1, such as from FR 2 628 471 A is known.
- a transmitter contained in the lock is activated when a person wants to use the lock and therefore a handle operated.
- a touch sensor responds to touching the handle or Motion sensor on the movement of the handle, which activates the transmitter to activate an electronic key that the person operating the lock Person carries with him. This turns on a transmitter in the key, and the The lock's antenna is switched to reception.
- the present invention is therefore based on the technical problem, a means of an identifier non-contact activatable lock of the generic type to be more functional.
- the electronic lock normally remains in the operational standby position, in a standby mode in which no high-frequency reading field is emitted.
- the evaluation and Control processor in the lock does not work at first.
- the antenna of the Reader in the castle which in itself is emitted by a transponder in the Identifier to be damped reading field, now acts according to the present invention So first as a receiving antenna for a work receiver.
- The provides a switch-on command for the operational readiness of Reader and processor as soon as it has high frequency contact via this reader antenna to a wake-up transmitter, with which the identifier in addition to his Code transponder is equipped. That transmitter is now on the transmitter antenna serving coupling coil of the transponder connected.
- the full operation with blasting of the reading field only starts when the Wake-up transmitter of an identifier to the wake-up receiver in the castle up to the point of detection approximated.
- the reading field that is switched on in this way switches the Alarm clock off. It activates the transponder in the usual way, to the in the Ident code stored identity code by amplitude modulation of the field to be transferred to the reader. If this code recorded by the reader with one stored in the reader, preferably in a non-volatile memory Comparison code in a predetermined manner, is the processor an electromechanical transducer for coupling the linkage to an outside the door accessible actuator to the latch-latch mechanism of the Lock released; otherwise the handle can be operated without mechanical action on the locking mechanism, turn freely.
- a door leaf is, for example, under the cover of its fitting, with a non-contact unlockable electronic lock 13 equipped, as in the above Main application explained in more detail.
- the latch 14 withdrawn from the striking plate of the door frame by means of a bolt 15 be when and as long as a handle 16 shown here as a knob brought into rotation in the linkage 17 via an electromechanical coupling 18 is.
- the clutch 18 is preferably engaged by means of a motor Converter 19, as soon as and as long as an enable signal 23 from a microprocessor 30 is supplied to a driver circuit 31 for the operation of the converter 19 becomes. This is the case when an identifier 25, one for opening the Authorized person carries a reading device 26 via an antenna 27 with a authorization code 29 stored in the memory 28 for control purposes becomes.
- Identifier 25 has an energy store 50 for operating a wake-up transmitter 51 equipped.
- the energy store 50 can be a primary cell like a button battery or around a secondary cell like a solar powered one physical or chemical charge storage (capacitor or Battery). It can be provided in the supply path for the wake-up transmitter 51 to provide a switch 52.
- the wake-up transmitter 51 can then be used as needed e.g. B. switched on by means of specific pressure on the identifier 25 in order not to continuously load the memory 50.
- the wake-up transmitter 51 in operation periodically sends a pulsed switch-on command 53, typically each from a decaying high-frequency oscillation of approximately the same frequency as that of the reading field 54. This can it via the resonance-tuned coupling coil of the transponder 56 in the identifier radiated and via the resonance coil of the reader antenna 27 are received, so that for the termination of the standby state there is no additional antenna effort.
- a pulsed switch-on command 53 typically each from a decaying high-frequency oscillation of approximately the same frequency as that of the reading field 54.
- the wake-up receiver 55 As soon as the wake-up receiver 55 has switched on the reading device 26 and consequently emits the reading field 54, becomes the passive transponder in the identifier 25 detected by this reading field 54 56 put into operation by means of energy inductively taken from the reading field 54, to switch off the alarm transmitter 51 and then the reading field 54 in rhythm with one dampen binary-coded identification codes 29 stored in the identification carrier 25. This is demodulated by the reading device 26 as amplitude modulation of the reading field 54 and fed into the processor 30 as the current identification code 29.
- the wake-up transmitter is 51 therefore switched off in order to avoid interference (for example as a result of a periodic superimposed switch-on commands 53). Only when it disappears of the reading field 54 radiated by the lock antenna 27, or outside of it Range, so when the transponder 56 is no longer working, the switches Wake-up transmitter 51 in the identification carrier 25 again (if necessary when the Switch 52).
- the processor 30 can also be equipped with an (internal or external) Timer 58 may be equipped, the lock 13 back into standby or Reset sleep state and thus the reading field 54 turns off when a predetermined Time span from the appearance of a radio-controlled activation command 53 or a manually triggered switch-on signal 57 has passed.
- Wake-up receiver 55 supplies a switch-on signal 57 to processor 30, around the reading field 54 for querying an identifier just brought into the vicinity 25 to be emitted.
- This emergency switch 42 is expediently connected to that of handle 16 to be operated outside the door because someone who is by wants to enter the door, inevitably tries to open the door Handle 16 to operate. If there is no switch-on command 53 for the Processor 30, clutch 18 is not engaged, however, so that handle 16 sympatheticed out empty. However, the emergency switch 42, such as a reed switch, is now used actuated by a permanent magnet pivotable with the handle 16 and thus manually triggered the emergency switch-on signal 57 to read field 54 To emit identification carrier query. In this way, the lock 13 is also by means of a passive identifier 25, namely not equipped with a wake-up transmitter 51 operable - but now not contactless, but only after activating the Processor 30 via the manually triggered switch-on signal 57.

Abstract
Description
Die Erfindung betrifft ein Schloß gemäß dem Oberbegriff des Anspruches 1, wie es etwa aus der FR 2 628 471 A bekannt ist. Dort ist eine Inbetriebnahme aus einem leistungsarmen Standby-Betrieb dadurch realisiert, daß ein im Schloß enthaltener Sender aktiviert wird, wenn eine Person das Schloß benutzen will und dafür eine Handhabe betätigt. Ein Berührungssensor spricht auf das Berühren der Handhabe oder ein Bewegungssensor auf die Bewegung der Handhabe an, wodurch der Sender aktiviert wird, um einen elektronischen Schlüssel zu aktivieren, den die das Schloß betätigende Person bei sich trägt. Dadurch wird nun ein Sender im Schlüssel eingeschaltet, und die Antenne des Schlosses wird auf Empfang umgeschaltet. Wenn der Schlüssel auf diese vom Schloß ausgehende Abfrage jetzt mit dem, in Bezug auf eine Vorgabe im Schloß, korrekten Codesignal antwortet, wird im Schloß eine mechanische Kupplung elektrisch aktiviert, um nun über weitere Betätigung der Handhabe den Sperrmechanismus des Schlosses manuell öffnen zu können. Nachteilig bei dieser Lösung ist allerdings vor allem der handhabungstechnische Aufwand, die Handhabe des Schlosses erst definiert betätigen zu müssen, damit das Schloß zunächst Sendekontakt zum Schlüssel aufnehmen und danach zur Verarbeitung der dann vom Schlüssel ausgesendeten Identinformation auf Empfang umschalten kann.The invention relates to a lock according to the preamble of claim 1, such as from FR 2 628 471 A is known. There is a commissioning from one Low-power standby mode realized in that a transmitter contained in the lock is activated when a person wants to use the lock and therefore a handle operated. A touch sensor responds to touching the handle or Motion sensor on the movement of the handle, which activates the transmitter to activate an electronic key that the person operating the lock Person carries with him. This turns on a transmitter in the key, and the The lock's antenna is switched to reception. If the key is on this query from the castle now with the, regarding a specification in the castle, correct code signal replies, a mechanical coupling becomes electrical in the lock activated in order to activate the locking mechanism of the To be able to open the lock manually. The main disadvantage of this solution, however, is the handling effort that defines the handling of the lock have to be actuated so that the lock first makes contact with the key and then for processing the identification information then sent out by the key can switch to reception.
Ein ähnliches Schloß mit Identträger-Aktivierung ist in der nicht-vorveröffentlichten DE 44 38 832 A beschrieben. Dort schränkt allerdings eine ständige Funktionsbereitschaft des Lesegerätes und des ihm nachgeschalteten Prozessors zur Abfrage und Auswertung des Codes eines etwa in die Nähe des Schlosses gelangenden Identträgers die Lebensdauer einer für den Betrieb des Schlosses erforderlichen Batterie stark ein, wenn das Schloß nicht autark, also nicht netzbetrieben sondern batteriebetrieben arbeitet. Außerdem kann erwartet werden, daß die Marktakzeptanz eines solchen codegesicherten Schlosses sich dadurch noch steigern läßt, daß nur im Bedarfsfalle - also nicht ständig - ein Hochfrequenz-Lesefeld vom Schloß abgestrahlt wird. A similar lock with identification activation is in the unpublished DE 44 38 832 A. However, there is a constant readiness to function there of the reading device and the processor connected to it for querying and evaluation of the code of an identifier who comes close to the castle Lifespan of a battery required for the operation of the lock strongly, if the lock is not self-sufficient, that is to say it does not operate on mains, but on batteries. In addition, it can be expected that the market acceptance of such a code-secured The lock can be increased by the fact that only when needed - not always - a high-frequency reading field is emitted from the castle.
Vorliegender Erfindung liegt deshalb die technische Problematik zugrunde, ein mittels eines Identträgers berührungslos aktivierbares Schloß gattungsgemäßer Art noch funktionaler auszulegen.The present invention is therefore based on the technical problem, a means of an identifier non-contact activatable lock of the generic type to be more functional.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß ein Schloß nach dem Oberbegriff des Hauptanspruches zusätzlich gemäß dessen Kennzeichnungsteil ausgelegt ist.This object is achieved in that a lock after The preamble of the main claim is additionally designed in accordance with its labeling part is.
Im Rahmen dieser Lösung, die dann im Patentanspruch 2 noch näher konkretisiert ist, verharrt das elektronische Schloß normalerweise in Funktionsbereitschafts-Ruhestellung, also in einem Standby-Betrieb, in welchem kein Hochfrequenz-Lesefeld abgestrahlt wird. Mangels Aufnahmemöglichkeit eines Ident-Codes muß somit auch der Auswerte- und Steuerungs-Prozessor im Schloß zunächst noch nicht arbeiten. Die Antenne des Lesegerätes im Schloß, die an sich dem Abstrahlen des durch einen Transponder im Identträger zu bedämpfenden Lesefeldes dient, wirkt gemäß vorliegender Erfindung nun also zunächst als Empfangsantenne für einen Wekkempfänger. Der liefert ein Einschaltkommando für die Funktionsbereitschaft von Lesegerät und Prozessor, sobald er über diese Lesegerät-Antenne Hochfrequenzkontakt zu einem Wecksender hat, mit dem der Identträger zusätzlich zu seinem Code-Transponder ausgestattet ist. Jener Sender ist an die nun als Sendeantenne dienende Koppelspule des Transponders angeschlossen.In the context of this solution, which is then further specified in claim 2, the electronic lock normally remains in the operational standby position, in a standby mode in which no high-frequency reading field is emitted. In the absence of an identification code, the evaluation and Control processor in the lock does not work at first. The antenna of the Reader in the castle, which in itself is emitted by a transponder in the Identifier to be damped reading field, now acts according to the present invention So first as a receiving antenna for a work receiver. The provides a switch-on command for the operational readiness of Reader and processor as soon as it has high frequency contact via this reader antenna to a wake-up transmitter, with which the identifier in addition to his Code transponder is equipped. That transmitter is now on the transmitter antenna serving coupling coil of the transponder connected.
Der volle Betrieb mit Abstrahlen des Lesefeldes setzt also erst ein, wenn sich der Wecksender eines Identträgers dem Weckempfänger im Schloß bis auf Auffaßnähe angenähert hat. Das dadurch eingeschaltete Lesefeld schaltet im Identträger den Wecksender ab. Es aktiviert in gewohnter Weise den Transponder, um den in den Identträger eingespeicherten Ident-Code durch Amplitudenmodulation des Feldes an das Lesegerät zu übertragen. Wenn dieser vom Lesegerät aufgenommene Code mit einem beim Lesegerät, vorzugsweise in einem nicht-flüchtigen Speicher, abgelegten Vergleichscode in vorgegebener Weise übereinstimmt, wird vom Prozessor ein elektromechanischer Wandler zum Ankuppeln des Gestänges eines außerhalb der Tür zugänglichen Betätigungselementes an die Riegel-Fallen-Mechanik des Schlosses freigegeben; andernfalls läßt die Handhabe sich, ohne mechanische Einwirkung auf den Schließmechanismus, frei durchdrehen. Allerdings ist es zweckmäßig, mit der Betätigung dieser Handhabe das Auslösen eines Einschaltsignales zum Lesegerät für den Fall zu koppeln, daß die Freigabe des externen Öffnungs- und Schließvorganges der Tür auch mittels eines Identträgers ohne aktive Weckeinrichtung ermöglicht werden soll, beispielsweise nach Ausfall des Wecksenders wegen Erschöpfung seines Energiespeichers im Identträger.The full operation with blasting of the reading field only starts when the Wake-up transmitter of an identifier to the wake-up receiver in the castle up to the point of detection approximated. The reading field that is switched on in this way switches the Alarm clock off. It activates the transponder in the usual way, to the in the Ident code stored identity code by amplitude modulation of the field to be transferred to the reader. If this code recorded by the reader with one stored in the reader, preferably in a non-volatile memory Comparison code in a predetermined manner, is the processor an electromechanical transducer for coupling the linkage to an outside the door accessible actuator to the latch-latch mechanism of the Lock released; otherwise the handle can be operated without mechanical action on the locking mechanism, turn freely. However, it is advisable triggering a switch-on signal when this handle is actuated to the reader in the event that the release of the external opening and the closing process of the door also by means of an identifier without an active alarm device should be possible, for example after the alarm transmitter fails due to exhaustion of its energy storage in the identifier.
Was die Codierung und die Funktion des Schlosses im übrigen betrifft, wird auf DE 44 38 832 A verwiesen.As far as the coding and the function of the lock is concerned, is on DE 44 38 832 A referenced.
Zusätzliche Alternativen und Weiterbildungen sowie weitere Merkmale und Vorteile dieser Zusatz - der Erfindung ergeben sich aus den weiteren Ansprüchen und, auch unter Berücksichtigung der abschließenden Darlegungen in der Zusammenfassung, aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das Wesentliche nach Art eines Blockschaltbildes stark abstrahiert skizzierten bevorzugten schaltungstechnischen Realisierungsbeispiels zur erfindungsgemäßen Lösung. Die einzige Figur der Zeichnung zeigt die periphere Beschaltung eines Prozessors für die vom Identträger aus aktivierbare Funktionsbereitschaft eines Schlosses. Additional alternatives and further training as well as further features and advantages this addition - the invention result from the further claims and, also taking into account the final explanations in the summary, from the following description of one in the drawing under restriction sketched in a highly abstracted manner to the essentials in the manner of a block diagram preferred circuit implementation example for the invention Solution. The only figure in the drawing shows the peripheral wiring a processor for the operational readiness that can be activated from the identifier of a castle.
Ein Türblatt ist, etwa unter der Blende seines Beschlages, mit einem berührungslos
freischaltbaren elektronischen Schloß 13 ausgestattet, wie in der eingangs zitierten
Hauptanmeldung näher erläutert. Zum Öffnen der Tür von außen kann die Falle 14
mittels eines Riegels 15 aus dem Schließblech des Türrahmens zurückgezogen
werden, wenn und solange eine hier als Drehknopf dargestellte Handhabe 16 damit
über eine elektromechanische Kupplung 18 im Gestäge 17 in Drehverbindung gebracht
ist. Das Einrücken der Kupplung 18 erfolgt vorzugsweise mittels eines motorischen
Wandlers 19, sobald und solange ein Freigabesignal 23 von einem Mikro-Prozessor
30 an eine Treiberschaltung 31 für den Betrieb des Wandlers 19 geliefert
wird. Das ist der Fall, wenn von einem Identträger 25, den eine zum Öffnen der
Tür befugte Person bei sich trägt, ein Lesegerät 26 über eine Antenne 27 mit einem,
zur Kontrolle auch im Speicher 28 abgelegten, Autorisierungs-Code 29 gespeist
wird.A door leaf is, for example, under the cover of its fitting, with a non-contact
unlockable
Um die Kapazität einer Batterie 38, aus der die beschriebenen Funktionen des
Schlosses 13 gespeist werden, zu schonen, ist das Schloß 13 in der Ruhefunktion
(bis auf einen Standby-Zustand minimalen Leistungserfordernisses) abgeschaltet.
Der Identträger 25 ist mit einem Energiespeicher 50 zum Betrieb eines Wecksenders
51 ausgestattet. Beim Energiespeicher 50 kann es sich um eine Primärzelle
wie eine Knopfbatterie oder um eine Sekundärzelle wie einen solarstromgespeisten
physikalischen oder chemischen Ladungsspeicher (Kondensator bzw.
Batterie) handeln. Es kann vorgesehen sein, im Versorgungsweg für den Wecksender
51 einen Schalter 52 vorzusehen. Über den kann dann der Wecksender 51 bedarfsweise
z. B. mittels spezifischer Druckausübung auf den Identträger 25 eingeschaltet
werden, um den Speicher 50 nicht ständig zu belasten. Jedenfalls liefert der
in Betrieb befindliche Wecksender 51 periodisch ein impulsförmiges Einschaltkommando
53, das typisch jeweils aus einer abklingenden Hochfrequenzschwingung
von etwa gleicher Frequenz wie der des Lesefeldes 54 besteht. Dadurch kann
es über die auf Resonanz abgestimmte Koppelspule des Transponders 56 im Identträger
abgestrahlt und über die ebenfalls auf Resonanz abgestimmte Spule der Lesegerät-Antenne
27 empfangen werden, so daß für die Beendigung des Standby-Zustandes
kein zusätzlicher Antennenaufwand anfällt. Sobald der Weckempfänger
55 das Lesegerät 26 eingeschaltet hat und jenes folglich das Lesefeld 54 abstrahlt,
wird im von diesem Lesefeld 54 erfaßten Identträger 25 der passive Transponder
56 mittels aus dem Lesefeld 54 induktiv entnommener Energie in Betrieb gesetzt,
um den Wecksender 51 abzuschalten und das Lesefeld 54 dann im Rhythmus eines
in den Identträger 25 eingespeicherten binärcodierten Ident-Codes 29 zu bedämpfen.
Das wird vom Lesegerät 26 als Amplitudenmodulation des Lesefeldes 54 demoduliert
und als aktueller Ident-Code 29 in den Prozessor 30 eingespeist.To the capacity of a battery 38 from which the described functions of
Castle 13 are fed, to protect the
Wegen Einzelheiten der Codierung und der Codeüberprüfung wird wiederum auf
DE 44 38 832 A verwiesen.
Jedenfalls kann man nun mittels der
Handhabe 16 wegen eingerückter Kupplung 18 den Riegel 15 (und damit beim
Öffnen auch die Falle 14) betätigen, wenn der Code-Vergleich 29-29 im Prozessor
30 positiv verläuft. Der Kupplungs-Treiber 31 wird allerdings vorsorglich nach
kurzer Zeitspanne zurückgeschaltet, um sicherheitshalber das Schloß 13 nicht in
Funktion zu belassen; danach muß erneut eine Abfrage des Transponders 36 erfolgen.Because of details of coding and code verification, turn on
DE 44 38 832 A referenced.
Anyway, you can now use the
Handle 16 due to engaged
Während jeden Auslesens eines Codes 29 mittels des Lesefeldes 54 ist der Wecksender
51 also abgeschaltet, um keine Störungen (etwa infolge eines periodisch
überlagerten Einschaltkommandos 53) entstehen zu lassen. Erst bei Verschwinden
des von der Schloß-Antenne 27 abgestrahlten Lesefeldes 54, bzw. außerhalb dessen
Reichweite, wenn also der Transponder 56 nicht mehr arbeitet, schaltet der
Wecksender 51 im Identträger 25 wieder ein (ggf. bei zusätzlicher Betätigung des
Schalters 52). Der Prozessor 30 kann ferner mit einer (internen oder externen)
Zeitschaltung 58 ausgestattet sein, die das Schloß 13 wieder in den Standby- oder
Schlafzustand rückversetzt und damit das Lesefeld 54 abschaltet, wenn eine vorgegebene
Zeitspanne ab Erscheinen eines über Funk ausgelösten Einschaltkommandos
53 oder eines manuell ausgelösten Einschaltsignales 57 verstrichen ist.During each reading of a
Wenn die Funktion des Wecksenders 51 gestört ist, so daß der Weckempfänger 55
nicht angesprochen werden kann, etwa wegen erschöpften Speichers 50 im Identträger
25, ist es an sich nicht möglich, das Lesefeld 54 über die Schloß-Antenne 27
abzustrahlen und durch Abrufen des Berechtigten-Codes 29 die Handhabe 16 kinematisch
an das Schloßgestänge 17 mit Falle 14 und Riegel 15 anzukoppeln. Um
dennoch das Lesegerät 26 und den Prozessor 30 für die Berechtigungs-Überprüfung
in Betrieb zu setzen, ist ein von außerhalb der Tür bedienbarer Notschalter
42 vorgesehen, der anstelle des auf das Einschaltkommando 53 ansprechenden
Weckempfängers 55 ein Einschaltsignal 57 an den Prozessor 30 liefert,
um das Lesefeld 54 zum Abfragen eines gerade in die Nähe verbrachten Identträgers
25 abzustrahlen. Zweckmäßigerweise ist dieser Notschalter 42 mit der von
außerhalb der Tür zu betätigenden Handhabe 16 gekoppelt, weil jemand, der durch
die Tür eintreten will, zwangsläufig versucht, diese zum Öffnen der Tür vorgesehene
Handhabe 16 zu betätigen. Bei fehlendem Einschaltkommando 53 für den
Prozessor 30 ist die Kupplung 18 aber nicht eingerückt, so daß die Handhabe 16
leer durchdreht. Dabei wird jedoch nun der Notschalter 42, etwa ein Reed-Schalter
von einem mit der Handhabe 16 verschwenkbaren Permanentmagneten, betätigt
und so manuell das Not-Einschaltsignal 57 ausgelöst, um das Lesefeld 54 zur
Identträger-Abfrage abzustrahlen. Auf diese Weise ist das Schloß 13 auch mittels
eines passiven, nämlich nicht mit Wecksender 51 ausgestatteten, Identträgers 25
bedienbar - nun allerdings nicht berührungslos, sondern erst nach Aktivierung des
Prozessors 30 über das nun manuell ausgelöste Einschaltsignal 57.If the function of the wake-

it normally assumes the idle stand-by position, in which its reading device (26) does not radiate a high-frequency read field (54) by way of its antenna (27) for releasing an identification code in the identification carrier (25), and in which consequently an evaluating and control processor (30) in the lock (13) does not work either; meanwhile the reading device's antenna (27) serves as receiving antenna for a possible switch-on command (53) from the ringing transmitter (51) in the identification carrier (25) to the ringing receiver (55) in the lock (13). - Lock according to Claim 2,
characterized in that
the ringing receiver (55) is connected to the same antenna (27) as a reading device (26) for the authorization code (29) stored in the identification carrier (25). - Lock according to Claim 2 or 3,
characterized in that
the ringing transmitter (51) is connected to the coupling coil of the reading device (26). - Lock according to Claim 2, 3 or 4,
characterized in that
the ringing transmitter (51) is switched off with the presence of the identification carrier (25) in the read field (54). - Lock according to one of Claims 2 to 5,
characterized in that
the switch-on command (53) is a periodically emitted, dying-out high-frequency pulse with approximately the same basic frequency as that of the read field (54). - Lock according to Claim 6,
characterized in that
the ringing transmitter (51) switches off when, after dying-out of its periodically emitted switch-on command (53), the high frequency from the read field (54) is still present at the coupling coil of the identification carrier's transponder (56). - Lock according to one of the preceding claims,
characterized in that
the release of a switch-on signal (57) is provided for by way of a manually operated emergency switch (42). - Lock according to Claim 8,
characterized in that
the emergency switch (42) is functionally in operative connection with the handle (16). - Lock according to one of the preceding claims,
characterized in that
the processor (30) is fitted with a time circuit (58) for switching the read field (54) off again.
