Description

Die Erfindung betrifft ein Verfahren zum Überwachen des Schließzustandes eines mit einem mechanischen Schlüssel betätigbaren Drehschlosses.The invention relates to a method for monitoring the closed state of a mechanical key operated rotary lock.

Bei Schlössern, insbesondere bei Türschlössern, wie dem Schloss einer Haus- oder Wohnungstüre, stellt sich häufig das Problem, dass ein Nutzer sich nicht mehr sicher ist, ob er das Türschloss abgeschlossen hat. Um diesem Problem zu begegnen, ist es aus der Praxis bekannt, derartige Schlösser mit einem Sensor zu versehen, der den Schließzustand erfasst, also ob das Schloss abgeschlossen ist oder nicht. Ein derartiger Sensor kann ein Signal, das den Schließzustand des Schlosses angibt, an ein Empfangsgerät versenden, so dass der Nutzer über den Schließzustand des Schlosses auch dann informiert werden kann, wenn er sich nicht am Ort des Schlosses befindet. Derartige Sensoren am Schloss sind jedoch nur aufwändig installierbar und erfordern in der Regel eine Modifikation der Tür, des Beschlages und/oder des Schlosses selbst. Darüber hinaus ist häufig eine elektrische Energieversorgung erforderlich, was mitunter das Verlegen einer Verkabelung in der der Tür benachbarten Wand erfordert.In locks, especially in door locks, such as the lock of a house or apartment door, often raises the problem that a user is no longer sure whether he has completed the door lock. To cope with this problem, it is known from practice to provide such locks with a sensor which detects the closed state, that is, whether the lock is completed or not. Such a sensor can send a signal indicating the closed state of the lock to a receiving device, so that the user can be informed about the closed state of the lock even if he is not at the site of the castle. However, such sensors on the lock are only consuming to install and usually require a modification of the door, the fitting and / or the lock itself. In addition, an electrical power supply is often required, which sometimes requires laying a wiring in the door adjacent wall ,

In der DE 196 54 443 A1 sind ein Verfahren und eine Vorrichtungen beschrieben, mit denen eine Änderung des Schließzustandes eines Schlosses erfasst bzw. der Schließzustand eines Schlosses festgestellt, gespeichert und ggf. weiterverarbeitet werden kann. Im ersten Fall wird eine Drehbewegung des Schlüssels erkannt, anhand derer festgestellt werden kann, ob das in Frage stehende Schloss auf- oder zugesperrt wird. Ein entsprechendes Signal wird an einen Speicher und eine Anzeige am Schlüssel bzw. Schlüsselanhänger übermittelt. Im zweiten Fall übermittelt das Schloss seinen Schließzustand, bevorzugt drahtlos, ebenfalls an einen Speicher und/oder an eine Anzeige am Schlüssel oder Schlüsselanhänger. Zusätzlich kann ein Identifikationssignal für das Schloss übertragen werden, so dass nicht nur eines, sondern mehrere Schlösser erkannt werden können. Es kann weiter eine Verknüpfung der entsprechenden Signale mit der relativen oder absoluten Zeit erfolgen.In the DE 196 54 443 A1 a method and a device are described with which detects a change in the closed state of a castle or the closed state of a castle can be detected, stored and possibly further processed. In the first case, a rotary movement of the key is detected, by which it can be determined whether the lock in question is opened or closed. A corresponding signal is transmitted to a memory and an indicator on the key or key fob. In the second case, the lock transmits its closed state, preferably wirelessly, also to a memory and / or to a display on the key or key fob. In addition, an identification signal for the lock can be transmitted, so that not only one, but several locks can be detected. It can further be a link of the corresponding signals with the relative or absolute time.

Die US 2011/285528 A1 beschreibt ein Verfahren zur Überwachung des Zustands eines Schlosses, bei dem die Schlüssel den Zustand der von ihnen geschlossenen bzw. geöffneten Schlösser drahtlos über Mobilfunkgeräte an einen zentralen Server weiterleiten.
Ausgehend von dieser Situation ist es die Aufgabe der Erfindung, eine einfache und effektive Möglichkeit bereitzustellen, ein herkömmliches Drehschloss hinsichtlich seines Schließzustandes zu überwachen.
Diese Aufgabe wird durch den Gegenstand des Patentanspruchs 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.
Die Erfindung liegt damit in einem Verfahren zum Überwachen des Schließzustandes eines mit einem mechanischen Schlüssel betätigbaren Drehschlosses, wobei

  • der Schlüssel mit einer Sensoreinrichtung versehen ist,
  • die Sensoreinrichtung einen Drehbewegungssensor, mit dem eine Drehbewegung des Schlüssels im Drehschloss erfasst wird, und einen Orientierungssensor aufweist, mit dem die Orientierung des Schlüssels während der Drehbewegung erfasst wird, auf der Grundlage der von dem Orientierungssensor während der Drehbewegung des Schlüssels erfassten Orientierung ermittelt wird, auf welcher Seite des Drehschlosses der Schlüssel betätigt worden ist, und
in Verbindung mit der von dem Drehbewegungssensor erfassten Drehbewegung des Schlüssels der Schließzustand des Drehschlosses ermittelt wird, wobei
mit dem Orientierungssensor die Orientierung des Schlüssels relativ zum magnetischen Nordpol der Erde erfasst wird. Es ist somit ein maßgeblicher Punkt der Erfindung, dass die Sensoreinrichtung zur Erfassung des Schließzustandes des Drehschlosses vollständig an dem mechanischen Schlüssel vorgesehen ist. Diese Sensorik weist neben einem Drehbewegungssensor, mit dem eine Drehbewegung des Schlüssels erfasst wird, auch einen Orientierungssensor auf, mit dem die Orientierung des Schlüssels während dieser Drehbewegung erfasst wird. Zur Erfassung des Schließzustandes des Drehschlosses kann damit zum einen, nämlich aufgrund der Richtung der Drehbewegung des Schlüssels, erfasst werden, ob das Drehschloss abgeschlossen oder aufgeschlossen worden ist. Zusätzlich ermöglicht der Orientierungssensor, die Orientierung des Schlüssels während des Auf- bzw. Abschließens, also während der Drehbewegung, zu erfassen, so dass damit auch erkannt werden kann, von welcher Richtung her der Schlüssel in das Drehschloss eingesteckt worden ist. Damit kann festgestellt werden, ob das Drehschloss von außen oder von innen auf- bzw. abgeschlossen worden ist. Neben dem Schließzustand - offen/geschlossen - ermöglicht das erfindungsgemäße Verfahren damit auch die Angabe, von wo - von innen/von außen - das Drehschloss ab- bzw. aufgeschlossen worden ist.The US 2011/285528 A1 describes a method for monitoring the state of a lock, in which the keys forward the state of the locks they have closed or opened wirelessly via mobile devices to a central server.
Based on this situation, it is the object of the invention to provide a simple and effective way to monitor a conventional rotary lock with respect to its closed state.
This object is solved by the subject matter of patent claim 1. Preferred developments of the invention are described in the subclaims.
The invention is thus in a method for monitoring the closed state of an operable with a mechanical key rotary lock, wherein
  • the key is provided with a sensor device,
  • the sensor device has a rotation sensor, which detects a rotational movement of the key in the rotary lock, and has an orientation sensor with which the orientation of the key is detected during the rotational movement, on the basis of the orientation detected by the orientation sensor during the rotary movement of the key, on which side of the rotary lock the key has been pressed, and
in conjunction with the detected by the rotary motion sensor rotational movement of the key, the closing state of the rotary lock is determined, wherein
the orientation sensor detects the orientation of the key relative to the magnetic north pole of the earth. It is thus an important point of the invention that the sensor device for detecting the closed state of the rotary lock is completely provided on the mechanical key. This sensor has, in addition to a rotary motion sensor, with which a rotational movement of the key is detected, also an orientation sensor, with which the orientation of the key is detected during this rotational movement. For detecting the closed state of the rotary lock can thus on the one hand, namely due to the direction of rotation of the key, be detected whether the rotary lock has been completed or unlocked. In addition, the orientation sensor allows to grasp the orientation of the key during the opening or closing, that is, during the rotational movement, so that it can also be detected, from which direction the key has been inserted into the rotary lock. It can thus be determined whether the rotary lock has been opened or closed from the outside or from the inside. In addition to the closed state - open / closed - the method according to the invention thus also allows the indication of where - from inside / outside - the rotary lock has been dismantled or unlocked.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist der Schlüssel mit einer Kommunikationseinrichtung zum drahtlosen Übertragen von Daten versehen, wobei Daten zu der von dem Drehbewegungssensor erfassten Drehbewegung des Schlüssels und Daten zu der Orientierung des Schlüssels während der Drehbewegung von der Kommunikationseinrichtung drahtlos an ein Empfangsgerät übertragen werden. Auf diese Weise kann der Schlüssel frei von irgendwelchen Anzeigeeinrichtungen bzw. Auswerteeinrichtungen gehalten werden, so dass er handlich und einfach betätigbar bleibt.According to a preferred development of the invention, the key is provided with a communication device for the wireless transmission of data, wherein data on the rotational movement of the key detected by the rotary motion sensor and data on the orientation of the key during the rotational movement are transmitted wirelessly from the communication device to a receiving device. In this way, the key can be kept free of any display devices or evaluation, so that it remains handy and easy to operate.

Vorzugsweise ist in diesem Zusammenhang weiterhin vorgesehen, dass die Ermittlung des Schließzustands des Drehschlosses und die Ermittlung der Orientierung des Schlüssels auf dem Empfangsgerät erfolgt. Gemäß einer bevorzugten Weiterbildung der Erfindung ist zusätzlich oder alternativ vorgesehen, dass die Empfangseinrichtung die empfangenen Daten oder davon abgeleitete Daten an einen Cloud-Dienst überträgt. Insofern sind auch eine Ermittlung des Schließzustands des Drehschlosses und die Ermittlung der Orientierung des Schlüssels während der Drehbewegung in dem Cloud-Dienst möglich. Insbesondere in diesem Zusammenhang ist es vorzugsweise vorgesehen, dass der Schlüssel mit einem Zwischenspeicher versehen ist, insbesondere um die an den Cloud-Dienst zu übertragenen Daten zwischenspeichern zu können, vorzugsweise in derartigen Fällen, in denen temporär keine Verbindung zu dem Cloud-Dienst besteht. Ganz besonders bevorzugt werden im Übrigen der Schließzustand des Drehschlosses und die Seite des Schlosses, auf der der Schlüssel betätigt worden ist, auf dem Empfangsgerät angezeigt.Preferably, it is further provided in this context that the determination of the closed state of the rotary lock and the determination of the orientation of the key takes place on the receiving device. According to a preferred embodiment of the invention, it is additionally or alternatively provided that the receiving device transmits the received data or data derived therefrom to a cloud service. In this respect, a determination of the closed state of the rotary lock and the determination of the orientation of the key during the rotation in the cloud service are possible. Particularly in this context, it is preferably provided that the key is provided with a buffer, in particular in order to be able to buffer the data to be transmitted to the cloud service, preferably in such cases in which there is temporarily no connection to the cloud service. Incidentally, the closed state of the rotary lock and the side of the lock on which the key has been pressed are most particularly indicated on the receiving device.

Als Orientierungssensor, mit dem die Orientierung des Schlüssels während der Drehbewegung erfasst wird, ist erfindungsgemäß ein derartiger Sensor vorgesehen, mit dem die Orientierung des Schlüssels relativ zum magnetischen Nordpol der Erde erfasst wird. Auf diese Weise kann ermittelt werden, in welche Himmelsrichtung der Schlüssel während der Drehbewegung weist. Bei einem normalen Drehschloss sind die Steckrichtungen für den mechanischen Schlüssel zum Betätigen des Drehschlosses auf der Innen- bzw. auf der Außenseite in der Regel einander entgegengesetzt. Bei der Angabe der Himmelsrichtung in Grad unterscheiden sich die Steckrichtungen beim Auf- bzw. Abschließen also in der Regel um 180 Grad.As an orientation sensor with which the orientation of the key is detected during the rotational movement, such a sensor is provided according to the invention, with which the orientation of the key relative to the magnetic north pole of the earth is detected. On In this way, it can be determined in which direction the key points during the rotational movement. In a normal rotary lock, the plug-in directions for the mechanical key for actuating the rotary lock on the inside and on the outside are usually opposite to each other. When specifying the direction of the compass in degrees, the plug-in directions when connecting and disconnecting generally differ by 180 degrees.

Zusätzlich oder alternativ zur Erfassung der Orientierung des Schlüssels relativ zum magnetischen Nordpol der Erde ist vorgesehen, mit dem Orientierungssensor die Orientierung des Schlüssels relativ zum Erdmittelpunkt zu erfassen. Dies ermöglicht es, nicht nur die Orientierung des Schlüssels in einer Himmelsrichtung anzugeben, sondern auch eine Aussage über die Neigung des Schlüssels zu treffen, entsprechend einer Richtungskomponente beim Stecken des Schlüssels nach oben bzw. nach unten.Additionally or alternatively, for detecting the orientation of the key relative to the magnetic north pole of the earth is provided with the orientation sensor to detect the orientation of the key relative to the center of the earth. This makes it possible not only to indicate the orientation of the key in a cardinal direction, but also to make a statement about the inclination of the key, according to a directional component when inserting the key up or down.

Ganz besonders bevorzugt ist dabei, dass der Orientierungssensor einen Magnetsensor zur Erkennung des Erdmagnetfelds aufweist. Alternativ ist die Ausgestaltung des Orientierungssensors mit anderweitigen Kompasseinrichtungen möglich.It is very particularly preferred that the orientation sensor has a magnetic sensor for detecting the geomagnetic field. Alternatively, the embodiment of the orientation sensor is possible with other compass devices.

Der Drehbewegungssensor kann unterschiedliche Parameter der Drehbewegung des Schlüssels beim Auf- bzw. Zuschließen des Drehschlosses erfassen. Gemäß einer bevorzugten Weiterbildung der Erfindung wird mit dem Drehbewegungssensor die Drehbewegung im Hinblick auf Drehrichtung, Drehgeschwindigkeit, Anzahl der Umdrehungen und/oder Winkel der Drehachse im Raum erfasst. Dies ermöglicht unterschiedliche Auswertungen, einschließlich der Erkennung von Nutzungs- und Bewegungsmustern und daraus resultierende Ableitung über Algorithmen über den Zustand des Drehschlosses.The rotary motion sensor can detect different parameters of the rotary movement of the key when opening or closing the rotary lock. According to a preferred embodiment of the invention, the rotational movement with respect to the direction of rotation, rotational speed, number of revolutions and / or angle of the axis of rotation in space is detected with the rotary motion sensor. This enables different evaluations, including the recognition of usage and movement patterns and the resulting derivation via algorithms about the state of the rotary lock.

Der Drehbewegungssensor kann dazu unterschiedliche Arten von Sensoren aufweisen, wie zum Beispiel ein Gyroskop. Gemäß einer bevorzugten Weiterbildung der Erfindung weist der Drehbewegungssensor jedoch einen Magnetsensor zur Erkennung des Erdmagnetfelds und/oder einen Beschleunigungssensor auf. Ganz besonders bevorzugt sind dabei der Orientierungssensor und der Drehbewegungssensor als ein gemeinsamer Magnetsensor zur Erkennung des Erdmagnetfelds ausgestaltet. Die Verwendung eines derartigen gemeinsamen Magnetsensors für den Orientierungssensor und den Drehbewegungssensor reduziert den Aufwand und ermöglicht insbesondere eine sehr einfache und kompakte Ausgestaltung der an dem Schlüssel vorgesehenen Sensoreinrichtung.The rotary motion sensor can for this purpose have different types of sensors, such as a gyroscope. According to a preferred embodiment of the invention, however, the rotary motion sensor has a magnetic sensor for detecting the geomagnetic field and / or an acceleration sensor. In this case, the orientation sensor and the rotary motion sensor are very particularly preferably configured as a common magnetic sensor for detecting the earth's magnetic field. The use of such a common magnetic sensor for the orientation sensor and the rotary motion sensor reduces the effort and in particular allows a very simple and compact design of the provided on the key sensor device.

Grundsätzlich kann eine von dem Schlüssel durchgeführte Drehbewegung von der Sensoreinrichtung auf unterschiedliche Weisen erfasst werden. Gemäß einer bevorzugten Weiterbildung der Erfindung ist jedoch vorgesehen, dass die Sensoreinrichtung derart an dem Schlüssel befestigt ist, dass eine von dem Schlüssel durchgeführte Drehbewegung auch von der Sensoreinrichtung durchgeführt wird. Dabei ist es nicht erforderlich, dass diese Drehbewegung des Schlüssels zu 100 % auch von der Sensoreinrichtung durchgeführt wird. Vielmehr ist es möglich, dass die Sensoreinrichtung relativ zum Schlüssel um einen maximalen vorbestimmten Winkel verdrehbar ist, vorzugsweise reversibel verdrehbar ist. Vorzugsweise beträgt dieser Winkel maximal 20 Grad, ganz besonders bevorzugt maximal 10 Grad.In principle, a rotational movement performed by the key can be detected by the sensor device in different ways. According to a preferred embodiment of the invention, however, it is provided that the sensor device is attached to the key such that a rotational movement performed by the key is also performed by the sensor device. It is not necessary that this rotational movement of the key is performed to 100% by the sensor device. Rather, it is possible that the sensor device is rotatable relative to the key by a maximum predetermined angle, preferably reversibly rotatable. Preferably, this angle is at most 20 degrees, most preferably at most 10 degrees.

Weiterhin ist gemäß einer bevorzugten Weiterbildung vorgesehen, dass die Sensoreinrichtung auf den Schlüsselkopf des Schlüssels aufgesetzt ist, vorzugsweise in der Art, dass ein die Sensoreinrichtung aufweisendes Gehäuse den Schlüsselkopf beidseitig umgreift.Furthermore, it is provided according to a preferred development that the sensor device is placed on the key head of the key, preferably in such a way that a housing having the sensor device enclosing the key head on both sides.

Nachfolgend wird die Erfindung anhand bevorzugter Ausführungsbeispiele unter Bezugnahme auf die Zeichnungen weiter im Detail erläutert.The invention will be explained in more detail below with reference to preferred embodiments with reference to the drawings.

Diese Anordnung kann weiterhin verwendet werden, wie der Schlüssel 1 alleine, da ein Nutzer des Schlüssels 1 diesen anstatt am Schlüsselkopf 4 am Gehäuse 6 halten und den Schlüssel 1 damit betätigen kann.Within the housing 6, an electric battery 7 for electrical power supply and a sensor and communication unit 8 are also provided. Thus, an arrangement is achieved in the assembled state, as from Fig. 1b seen in the case of the housing 6 only the beard 9 of the key 1 protrudes. This arrangement can continue to be used as the key 1 alone, as a user of the key 1 can hold this instead of the key head 4 on the housing 6 and the key 1 can operate with it.

In Fig. 2 ist die Sensor- und Kommunikationseinheit 8 schematisch im Detail dargestellt. Die Sensor- und Kommunikationseinheit 8 weist eine Sensoreinrichtung 10 und eine mit dieser verbundenen Kommunikationseinrichtung 11 auf. Wie mit dem Doppelpfeil angedeutet, ist die Kommunikationseinrichtung 11 zum drahtlosen Übertragen von Daten eingerichtet. Vorliegend handelt es sich bei der Kommunikationseinrichtung 11 um ein Bluetooth-Modul nach dem Standard 4.0.In Fig. 2 the sensor and communication unit 8 is shown schematically in detail. The sensor and communication unit 8 has a sensor device 10 and a communication device 11 connected thereto. As indicated by the double arrow, the communication device 11 is set up to wirelessly transmit data. In the present case, the communication device 11 is a Bluetooth module according to the 4.0 standard.

Die Sensoreinrichtung 10 wird vorliegend von einem Magnetsensor zur Erkennung des Erdmagnetfelds gebildet. Dieser Magnetsensor dient einerseits als Drehbewegungssensor, mit dem eine Drehbewegung des Schlüssels 1 erfassbar ist. Darüber hinaus dient dieser Magnetsensor auch als Orientierungssensor, mit dem die Orientierung des Schlüssels 1 während seiner Drehbewegung erfasst werden kann. Die Daten hinsichtlich einer erfassten Drehbewegung sowie der Orientierung des Schlüssels 1 während dieser Drehbewegung können von der Sensoreinrichtung 10 an die Kommunikationseinrichtung 11 übertragen werden, die ihrerseits diese Daten drahtlos, vorliegend per Bluethooth, an eine weitere Einrichtung übermitteln kann.The sensor device 10 is presently formed by a magnetic sensor for detecting the geomagnetic field. This magnetic sensor serves on the one hand as a rotary motion sensor with which a rotary movement of the key 1 can be detected. In addition, this magnetic sensor also serves as an orientation sensor with which the orientation of the key 1 can be detected during its rotation. The data regarding a detected rotational movement and the orientation of the key 1 during this rotational movement can be transmitted from the sensor device 10 to the communication device 11, which in turn can transmit this data wirelessly, in this case via Bluethooth, to a further device.

Aus Fig. 3 ist schematisch ein Anwendungsfall gemäß einem bevorzugten Ausführungsbeispiel der Erfindung ersichtlich. Der Schlüssel 1 ist mit einer Zusatzeinrichtung 2 versehen, wie zuvor beschrieben, so dass der Nutzer den Schlüssel 1 an dem Gehäuse 6 der Zusatzeinrichtung 2 greifen und somit den Bart 9 des Schlüssels 1 in ein Drehschloss 12 einführen kann, um das Drehschloss 12 auf- oder zuzuschließen. Das Drehschloss 10 ist vorliegend in einer Türe 13 angeordnet und dient zum Abschließen derselben.Out Fig. 3 is schematically a use case according to a preferred embodiment of the invention can be seen. The key 1 is provided with an additional device 2, as described above, so that the user can grip the key 1 on the housing 6 of the additional device 2 and thus insert the beard 9 of the key 1 into a rotary lock 12 in order to mount the rotary lock 12. or close. The rotary lock 10 is presently arranged in a door 13 and serves to complete the same.

Um nun für einen Nutzer erfassen und darstellen zu können, ob das Drehschloss 10 der Tür 11 abgeschlossen oder offen ist, ist die Sensor- und Kommunikationseinheit 8 der Kommunikationseinrichtung 11 per Bluetooth mit einem Empfangsgerät 14, vorliegend einem Smartphone, verbunden. Die von dem Magnetsensor zur Drehbewegung sowie zur Lage des Schlüssels 1 während der Drehbewegung erfassten Daten werden mittels der Kommunikationseinrichtung 11 an das Empfangsgerät 14 übertragen und dort hinsichtlich der Fragen ausgewertet, ob das Drehschloss 12 der Tür 13 abgeschlossen oder verschlossen ist sowie von welcher Seite der Schlüssel 1 betätigt worden ist, also von außen oder von innen. Diese Informationen sind auf dem Empfangsgerät 14 für den Nutzer darstellbar, so dass der Nutzer auch später noch, also nachdem er mit dem Schlüssel 1 das Drehschloss 12 betätigt hat, überprüfen kann, wie der Schließzustand des Drehschlosses 12 ist.In order to be able to record and display for a user whether the rotary lock 10 of the door 11 is closed or open, the sensor and communication unit 8 of the communication device 11 is connected via Bluetooth to a receiving device 14, in the present case a smartphone. The detected by the magnetic sensor for rotational movement and the position of the key 1 during the rotation data are transmitted by the communication device 11 to the receiving device 14 and evaluated there in terms of questions whether the rotary lock 12 of the door 13 is completed or closed and from which side of the Key 1 has been pressed, ie from the outside or from the inside. This information can be displayed on the receiving device 14 for the user, so that the user later, so after he has operated the rotary lock 12 with the key 1, can check how the closed state of the rotary lock 12.

Darüber hinaus ist das Empfangsgerät 14 über eine WLAN-Verbindung mit einem Router 15 verbunden, so dass die Daten zum Schließzustand des Drehschlosses 12 sowie zu der Frage, ob das Drehschloss 12 von außen oder von innen betätigt worden ist, über das Internet 16 an einen Cloud-Dienst 17 übertragen werden kann. Dieser Cloud-Dienst 17 kann, ebenfalls über das Internet 16, über einen anderen Router 18 von einem anderen Gerät 19, wie einem PC, kontaktiert werden, um auch dort Zugriff zu den Informationen zu erhalten, wie der Schließzustand des Drehschlosses 12 ist und von welcher Seite das Drehschloss 12 betätigt worden ist.In addition, the receiving device 14 is connected to a router 15 via a WLAN connection, so that the data on the closing state of the rotary lock 12 and on the question of whether the rotary lock 12 has been actuated from the outside or from the inside via the Internet 16 to a Cloud service 17 can be transferred. This cloud service 17 can also be contacted via the Internet 16 via another router 18 from another device 19, such as a PC, to access the information there as well to obtain how the closed state of the rotary lock 12 and from which side the rotary lock 12 has been operated.

In Fig. 3 ist dargestellt, dass das andere Gerät kabelverbunden mit dem Router 18 verbunden ist. Selbstverständlich ist es auch möglich, ein weiteres mobiles Gerät 20 zu verwenden, um die Informationen zum Schließzustand und zum Ort, von wo das Drehschloss 12 betätigt worden ist, abzurufen. Darüber hinaus ist es natürlich auch möglich, andere, vorliegend nicht dargestellte Schlüssel für das Drehschloss 12 ebenfalls jeweils mit einer Sensor- und Kommunikationseinheit, wie zuvor beschrieben, auszustatten. Auf diese Weise können über den Cloud-Dienst 17 für einer Vielzahl von Nutzern die Informationen verfügbar gemacht werden, wie der aktuelle Schließzustand des Drehschlosses 12 ist und ob das Drehschloss 12 zuletzt von außen oder innen betätigt worden ist, auch wenn das Drehschloss 12 nicht von ihnen selbst betätigt worden ist.In Fig. 3 It is shown that the other device is cable connected to the router 18. Of course, it is also possible to use another mobile device 20 to retrieve the information about the closed state and the location from where the rotary lock 12 has been operated. In addition, it is of course also possible, other, not shown here key for the rotary lock 12 also each with a sensor and communication unit, as described above, equip. In this way, the information can be made available to a plurality of users via the cloud service 17, such as the current closing state of the rotary lock 12 and whether the rotary lock 12 has been actuated last from the outside or inside, even if the rotary lock 12 is not from they themselves have been operated.
