Abstract

The lock can be opened by an authorised person carrying a device (25) which includes a passive transponder (56) and memory containing a binary authorisation code (29). The outer handle (16) of the door can act on the closure mechanism only when the code supplied from the transponder agrees with the content of the memory (28) of the lock. The transponder is interrogated (54) and the code reader (26) activated only when a periodic switching command (53) is taken up by an alarm transmitter (51), with battery (50), or in emergency when a manual switch (42) is closed.

Description

Die Erfindung betrifft ein Schloß gemäß dem Oberbegriff des Anspruches 1.The invention relates to a lock according to the preamble of claim 1.

Jenes Konzept nach dem Hauptpatent hat sich in sicherheitstechnischer und in handhabungstechnischer Hinsicht sehr bewährt. Problematisch ist lediglich die Energiebilanz in Hinblick auf einen autarken, also nicht netzbetriebenen sondern batteriebetriebenen Einsatz eines solchen Schlosses. Denn die ständige Funktionsbereitschaft des Lesegerätes und des ihm nachgeschalteten Prozessors zur Abfrage und Auswertung des Codes eines etwa in die Nähe des Schlosses gelangenden Identträgers schränkt die Lebensdauer einer Batterie sehr ein. Außerdem kann erwartet werden, daß die Marktakzeptanz eines solchen codegesicherten Schlosses sich dadurch noch steigern läßt, daß nur im Bedarfsfalle aber nicht ständig das Hochfrequenz-Lesefeld abgestrahlt wird. Aus diesen Überlegungen heraus liegt vorliegender Zusatzerfindung die technische Problematik zugrunde, ein mittels eines Identträgers berührungslos aktivierbares Schloß nach dem Hauptpatent noch funktionaler auszulegen.That concept based on the main patent has proven itself very well in terms of safety and handling. The only problem is the energy balance with regard to an autonomous, i.e. not mains-operated but battery-operated use of such a lock. This is because the permanent readiness of the reader and the processor connected to it to query and evaluate the code of an identifier that comes close to the lock greatly limits the lifespan of a battery. In addition, it can be expected that the market acceptance of such a code-secured lock can be increased even further by the fact that the high-frequency reading field is not continuously emitted only when needed. Based on these considerations, the present additional invention is based on the technical problem of designing a lock according to the main patent to be contactlessly activatable by means of an identification carrier.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß ein Schloß gemäß dem Oberbegriff des Hauptanspruches zusätzlich gemäß dessen Kennzeichnungsteil ausgestattet ist.This object is achieved in that a lock according to the preamble of the main claim is additionally equipped according to the characterizing part.

Nach dieser Lösung verharrt das elektronische Schloß normalerweise in Funktionsbereitschafis-Ruhestellung (Standby-Betrieb), in der kein Hochfrequenz-Lesefeld abgestrahlt wird und somit mangels Aufnahmemöglichkeit eines Ident-Codes auch der Auswerte- und Steuerungs-Prozessor nicht arbeiten muß. Die Antenne des Lesegerätes, die an sich dem Abstrahlen eines durch einen Transponder zu bedämpfenden Lesefeldes dient, wirkt nun als Empfangsantenne für einen Weckempfänger. 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.According to this solution, the electronic lock normally remains in the operational ready position (standby mode), in which no high-frequency reading field is emitted, and therefore the evaluation and control processor does not have to work due to the lack of an identification code. The antenna of the reading device, which in itself serves to emit a reading field to be attenuated by a transponder, now acts as a receiving antenna for one Wake-up receiver. The provides a switch-on command for the readiness of the reader and processor as soon as it has high-frequency contact via this reader antenna with a wake-up transmitter with which the identifier is equipped in addition to its code transponder. That transmitter is connected to the coupling coil of the transponder which now serves as the transmitting antenna.

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.Full operation with radiation of the reading field only begins when the wake-up transmitter of an identifier has approached the wake-up receiver in the castle up to the point of detection. The reading field that is switched on in this way switches off the alarm transmitter in the identifier. It activates the transponder in the usual way in order to transmit the identification code stored in the identification carrier to the reading device by means of amplitude modulation of the field. If this code recorded by the reading device matches a comparison code stored in the reading device, preferably in a non-volatile memory, in a predetermined manner, the processor processes an electromechanical converter for coupling the linkage of an actuating element which is accessible outside the door to the bolt-latch mechanism of the Lock released; otherwise the handle can be turned freely without mechanical action on the locking mechanism. However, it is useful to couple the triggering of a switch-on signal to the reader with the actuation of this handle in the event that the release of the external opening and closing process of the door should also be made possible by means of an identifier without an active wake-up device, for example after the wake-up transmitter has failed Exhaustion of his energy storage in the identifier.

Was die Codierung und die Funktion des Schlosses im übrigen betrifft, wird auf das Hauptpatent verwiesen.As far as the coding and the function of the lock are concerned, reference is made to the main patent.

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 developments as well as further features and advantages of this addition - the invention result from the further claims and, also taking into account the concluding explanations in the summary, from the following description of a highly abstracted in the drawing, limited to the essentials in the manner of a block diagram outlined preferred circuit implementation example for the solution according to the invention. The only figure in the drawing shows the peripheral circuitry of a processor for the operational readiness of a lock that can be activated from the identifier.

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 equipped, for example, under the cover of its fitting, with a contactlessly unlockable electronic lock 13, as explained in more detail in the main application cited at the beginning. To open the door from the outside, the latch 14 can be withdrawn from the striking plate of the door frame by means of a latch 15 if and as long as a handle 16, shown here as a rotary knob, is thus brought into rotation via an electromechanical coupling 18 in the linkage 17. The clutch 18 is preferably engaged by means of a motorized converter 19 as soon as and as long as an enable signal 23 is supplied by a microprocessor 30 to a driver circuit 31 for the operation of the converter 19. This is the case when an identification carrier 25, which a person authorized to open the door carries with him, feeds a reader 26 via an antenna 27 with an authorization code 29, which is also stored in the memory 28 for control purposes.

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 anfallt. 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.In order to conserve the capacity of a battery 38 from which the described functions of the lock 13 are fed, the lock 13 is switched off in the idle function (except for a standby state with minimal power requirement). The identification carrier 25 is equipped with an energy store 50 for operating a wake-up transmitter 51. The energy storage device 50 can be a primary cell such as a button battery or a secondary cell such as a physical or chemical charge store (capacitor or battery) powered by solar power. It can be provided to provide a switch 52 in the supply path for the wake-up transmitter 51. Then the wake-up transmitter 51 can, if necessary, for. B. be switched on by means of specific pressure exerted on the identification carrier 25 in order not to continuously load the memory 50. In any case, the wake-up transmitter 51 in operation periodically supplies a pulse-shaped switch-on command 53, which typically consists of a decaying high-frequency oscillation of approximately the same frequency as that of the reading field 54. As a result, it can be emitted via the coupling coil of the transponder 56, which is tuned to resonance, in the identification carrier and received via the coil of the reader antenna 27, which is also tuned to resonance, so that there is no additional antenna expenditure for ending the standby state. As soon as the wake-up receiver 55 has switched on the reading device 26 and consequently emits the reading field 54, the passive transponder 56 is put into operation in the identifier 25 detected by this reading field 54 by means of energy inductively extracted from the reading field 54, to switch off the wake-up transmitter 51 and then dampen the reading field 54 in the rhythm of a binary-coded identification code 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.

Wegen Einzelheiten der Codierung und der Codeüberprüfung wird wiederum auf die Darlegungen und Verweisungen in der Anmeldung zum Hauptpatent ausdrücklich und voll-inhaltlich Bezug genommen. 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 19-19 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.For details of the coding and the code review, the explanations and references in the application for the main patent are again expressly and fully referred to. In any case, the handle 15 can now be actuated by means of the handle 16 because of the engaged clutch 18 (and thus also the latch 14 when opening) if the code comparison 19-19 in the processor 30 is positive. As a precaution, the clutch driver 31 is switched back after a short period of time in order not to leave the lock 13 in operation for safety reasons; the transponder 36 must then be queried again.

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 code 29 by means of the reading field 54, the wake-up transmitter 51 is therefore switched off in order not to cause interference (for example as a result of a periodically superimposed switch-on command 53). Only when the reading field 54 emitted by the lock antenna 27 disappears, or outside of its range, ie when the transponder 56 no longer works, does the wake-up transmitter 51 in the identification carrier 25 switch on again (if necessary, with additional actuation of the switch 52). The processor 30 can also be equipped with an (internal or external) timer circuit 58 which resets the lock 13 to the standby or sleep state and thus switches off the reading field 54 if a predetermined period of time from the appearance of a radio-controlled switch-on command 53 or one manually triggered switch-on signal 57 has passed.

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 Weckenpfängers 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 24 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-up transmitter 51 is disturbed, so that the wake-up receiver 55 cannot be addressed, for example because of an exhausted memory 50 in the identification carrier 25, it is not possible in itself to emit the reading field 54 via the lock antenna 27 and by calling up the authorized person -Codes 29 to couple the handle 16 kinematically to the lock linkage 17 with latch 14 and bolt 15. In order to nevertheless put the reader 26 and the processor 30 into operation for the authorization check, an emergency switch 42 which can be operated from outside the door is provided and which supplies a switch-on signal 57 to the processor 30 instead of the alarm receiver 55 which responds to the switch-on command 53, in order to emit the reading field 54 for querying an identifier 25 that has just been brought into the vicinity. This emergency switch 24 is expediently coupled to the handle 16 to be actuated from outside the door, because someone who wants to enter through the door inevitably tries to actuate the handle 16 provided for opening the door. In the absence of a switch-on command 53 for the processor 30, the clutch 18 is not engaged, however, so that the handle 16 spins empty. In this case, however, the emergency switch 42, for example a reed switch, is actuated by a permanent magnet which can be pivoted with the handle 16, and the emergency switch-on signal 57 is thus triggered manually in order to emit the reading field 54 for querying the identifier. In this way, the lock 13 can also be operated by means of a passive identifier 25, which is not equipped with a wake-up transmitter 51 - but now not without contact, but only after the processor 30 has been activated via the manually triggered switch-on signal 57.
