Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, auf kostengünstige Art und Weise eine Vorrichtung zu schaffen, dessen Magnetfeldsensoranordnung es ermöglicht, bei besonders kompakter Bauform durch die Ermittlung der Magnetfeldausrichtung eines einzigen Magneten, beziehungsweise durch Ermittlung dessen Lage im Raum, sowohl den Status "geschlossen", den Status "aufgeschwenkt" oder den Status "aufgekippt" einer beweglichen Verschlusseinrichtung festzustellen, den festgestellten Status auszuwerten und an eine nachgelagerte Gebäudeeinrichtungen zu übertragen.The present invention is therefore an object of the invention to provide a device in a cost-effective, the magnetic field sensor arrangement allows, in a particularly compact design by determining the magnetic field orientation of a single magnet, or by determining its location in space, both the status "closed "to determine the status" swung open "or the status" tilted "of a movable locking device, to evaluate the status established and to transmit it to a downstream building facility.

Wie aus den Zeichnungen hervorgeht, ist eine solche Vorrichtung zur Lageermittlung eines einzigen Magneten 1 vorgesehen, welcher an einer beweglichen Verschlusseinrichtung einer Gebäudeöffnung angebracht ist. Die als Fenster 2 ausgeführte bewegliche Verschlusseinrichtung ist fest an einer mit dem Gebäude verbundenen Zarge 3 gelagert. Eine einzige, kompakt aufgebaute Magnetfeldsensoranordnung 4 ist zur Lageermittlung des Magneten 1 vorgesehen und zu diesem Zweck an der fest mit dem Gebäude verbundenen Zarge 3 angebracht. Die Magnetfeldsensoranordnung 4 weist eine Messeinrichtung 5 auf, welche durch Messung der Magnetfeldausrichtung in drei orthogonal zueinander angeordneten Ebenen die Lage des am Fenster 2 angebrachten Magneten 1 relativ zur Messeinrichtung 5 ermittelt. Zudem weist die Magnetfeldsensoranordnung 4 eine Auswerteeinheit 6 auf, welche die ermittelte Lage des Magneten 1 dem damit korrespondierenden Status des Fensters 2 zuordnet. Außerdem weist die Magnetfeldsensoranordnung 4 eine Sendeeinrichtung 7 auf, welche den ermittelten Status des Fensters 2 an eine nachgelagerte - der Einfachheit nicht dargestellten - Gebäudeeinrichtung übermittelt. Eine solche nachgelagerte Gebäudeeinrichtung kann zum Beispiel als Heizungssteuerung, Überwachungsanlage, Alarmanlage und so weiter ausgeführt sein. Für solche Gebäudeeinrichtungen ist die Information über den momentanen Status der beweglichen Verschlusseinrichtung (Fenster 2, Tür) wichtig, um entsprechende Maßnahmen, wie Absenken der Heiztemperatur, Beeinflussung eines Heizkörperthermostaten, Abgabe einer Warnmeldung und so weiter durchführen zu können. Als Status ist beim vorliegenden Ausführungsbeispiel von Bedeutung, ob das Fenster 2 geschlossen, verriegelt, aufgeschwenkt oder aufgekippt ist, um verschiedene Maßnahmen durchführen zu können. Beim vorliegenden Ausführungsbeispiel ist die Gebäudeeinrichtung als Steuerzentrale eines Gebäudeautomationssystems ausgeführt.As is apparent from the drawings, such a device for determining the position of a single magnet 1 is provided, which is attached to a movable closure device of a building opening. The movable closure device designed as a window 2 is fixedly mounted on a frame 3 connected to the building. A single, compact magnetic field sensor assembly 4 is provided for determining the position of the magnet 1 and attached for this purpose to the frame 3 fixedly connected to the building. The magnetic field sensor arrangement 4 has a measuring device 5, which determines the position of the magnet 1 mounted on the window 2 relative to the measuring device 5 by measuring the magnetic field orientation in three orthogonal planes. In addition, the magnetic field sensor arrangement 4 has an evaluation unit 6, which assigns the determined position of the magnet 1 to the status of the window 2 corresponding thereto. In addition, the magnetic field sensor arrangement 4 has a transmitting device 7, which transmits the determined status of the window 2 to a downstream building device, which is not shown for simplicity. Such a downstream building device can be designed, for example, as a heating control, monitoring system, alarm system and so on. For such building equipment, the information about the current status of the movable shutter (window 2, door) is important to be able to perform appropriate actions such as lowering the heating temperature, influencing a radiator thermostat, issuing a warning message and so on. As a status is important in the present embodiment, whether the window 2 is closed, locked, swung open or tipped to perform various measures can. In the present embodiment, the building device is designed as a control center of a building automation system.

Gegebenenfalls kann die Messeinrichtung 5 der Magnetfeldsensoranordnung 4 auch dazu vorgesehen sein, zusätzlich die Stärke des Erdmagnetfeldes zu erfassen, um bei Bedarf eine dreidimensionale Lageermittlung der Magnetfeldsensoreinrichtung 4 im Raum durchzuführen zu können.Optionally, the measuring device 5 of the magnetic field sensor arrangement 4 can also be provided to additionally detect the strength of the geomagnetic field in order to perform a three-dimensional position determination of the magnetic field sensor device 4 in the room if necessary.

Wie des Weiteren insbesondere aus Figur 3 hervorgeht, ist der Magnet 1 beim vorliegenden Ausführungsbeispiel an einem verstellbaren Riegelteil 8 des Fensters 2 angebracht. Im vorliegenden Fall ist der Magnet 1 als Neodym-Magnet ausgeführt und auf die Stirnseite des als Zapfens ausgeführten verstellbaren Riegelteils 8 aufgeklebt. Bei besonders kompakter Bauform des Magneten 1 ist somit nicht nur für eine besonders gut sensierbare Magnetfeldausrichtung Sorge getragen, zudem ist auch die Anbringung des Magneten 1 durch den Benutzer besonders einfach. Es ist somit eine Lösung geschaffen, welche sich auch besonders gut für eine Nachrüstung eignet.As further particularly from FIG. 3 As can be seen, the magnet 1 is attached to an adjustable latch part 8 of the window 2 in the present embodiment. In the present case, the magnet 1 is designed as a neodymium magnet and adhered to the end face of the adjustable bolt portion 8 designed as a pin. In a particularly compact design of the magnet 1 is thus not only for a particularly good sensible magnetic field alignment care, also the attachment of the magnet 1 by the user is particularly simple. It is thus created a solution which is also particularly suitable for retrofitting.

Wie insbesondere aus den Figuren 1 und 2 hervorgeht, gilt gleiches auch für die Magnetfeldsensoranordnung 4 der Vorrichtung. Diese ist ebenfalls besonders kompakt ausgeführt und lässt sich ebenfalls durch eine Verklebung und/oder Verschraubung auf einfache Art und Weise an der feststehenden Zarge 3 des Fensters 2 durch den Benutzer anbringen. Die Magnetfeldsensoranordnung 4 weist ein - der Einfachheit halber nicht dargestelltes - Gehäuse auf, welches - wie bereits erwähnt - auf einfache Art und Weise die Befestigung an der Zarge 3 ermöglicht und in welchem sowohl die Messeinrichtung 5, die Auswerteeinheit 6 und die Sendeeinrichtung 7 untergebracht sind. Zur Anordnung und Verschaltung ist lediglich eine einzige elektrische Leiterplatte vorgesehen, die neben einem Mikrokontroller und weiteren zur Funktion notwendigen elektrischen/elektronischen Bauteilen mit der Messeinrichtung 5, mit der Auswerteeinheit 6 und mit der Sendeeinrichtung 7 versehen ist. Zur Energieversorgung der zur Funktion notwendigen Bauteile steht die Leiterplatte mit einer Batterie 9 elektrisch leitend in Verbindung, welche ebenfalls im Gehäuse der Magnetfeldsensoranordnung 4 untergebracht ist.As in particular from the Figures 1 and 2 shows, the same applies to the magnetic field sensor arrangement 4 of the device. This is also made very compact and can also be attached by a bond and / or screw easily on the fixed frame 3 of the window 2 by the user. The magnetic field sensor arrangement 4 has a housing (not shown for the sake of simplicity), which-as already mentioned-enables the attachment to the frame 3 in a simple manner and in which both the measuring device 5, the evaluation unit 6 and the transmitting device 7 are accommodated , For arrangement and interconnection, only a single electrical circuit board is provided which is provided in addition to a microcontroller and other necessary for the function of electrical / electronic components with the measuring device 5, with the evaluation unit 6 and with the transmitting device 7. To supply energy to the components necessary for the function, the printed circuit board is electrically connected to a battery 9, which is likewise accommodated in the housing of the magnetic field sensor arrangement 4.

Die Messeinrichtung 5 ist beim vorliegenden Ausführungsbeispiel als dreidimensionaler Hall-Sensor ausgeführt. Dieser sensiert die Magnetfeldausrichtung des Magneten 1 in drei orthogonal zueinander stehenden Ebenen. Die Messwerte werden digitalisiert und der Auswerteeinheit 6 bereitgestellt.The measuring device 5 is designed in the present embodiment as a three-dimensional Hall sensor. This senses the magnetic field alignment of the magnet 1 in three mutually orthogonal planes. The measured values are digitized and provided to the evaluation unit 6.

Die Auswertung erfolgt in der Auswerteeinheit 6 über eine Logik in einem Mikrokontroller. Die Messwerte werden über ein digitales Interface von der Messeinrichtung 5 bereitgestellt. Liegen die Messwerte innerhalb eines zum Status zugehörigen Messwertebereichs, erfolgt die Zuordnung der Messwerte zu dem betreffenden Status des Fensters 2. Ein regelmäßiges Statusupdate und Änderungen des Status des Fensters 2 führen zum Senden des ermittelten Status an die Steuerzentrale des Gebäudeautomationssystems.The evaluation takes place in the evaluation unit 6 via a logic in a microcontroller. The measured values are provided by the measuring device 5 via a digital interface. If the measured values lie within a measured value range associated with the status, the measured values are assigned to the relevant status of window 2. A regular status update and changes to the status of window 2 lead to the transmission of the determined status to the control center of the building automation system.

Das Senden des sensierten Status der Messeinrichtung 5 erfolgt über die Sendeeinrichtung 7 mittels Funk an die Steuerzentrale des Gebäudeautomationssystems. Die Steuerzentrale verknüpft mit dem empfangenen Status programmierte Maßnahmen. Wird zum Beispiel das Fenster 2 in einem Raum geöffnet, so beeinflusst die Steuerzentrale die Heizungssteuerung, damit diese zum Beispiel in dem betreffenden Raum die Ventile der Heizkörper schließt. Des Weiteren kann die Steuerzentrale für den Benutzer zum Beispiel Informationen bereitstellen. Wird das betreffende Gebäude zum Beispiel vom Benutzer verlassen, kann dieser über eine Statusabfrage sicherstellen, ob alle Fenster 2 beziehungsweise Türen des Gebäudes beziehungsweise eines bestimmten Raumes ordnungsgemäß verschlossen sind.The transmission of the sensed status of the measuring device 5 via the transmitting device 7 by radio to the control center of the building automation system. The Control Center associates programmed actions with the received status. If, for example, the window 2 is opened in a room, the control unit influences the heating control so that it closes the valves of the radiators in the relevant room, for example. Further, the control center may, for example, provide information to the user. If the building concerned is left by the user, for example, the latter can use a status query to ensure that all windows 2 or doors of the building or a specific room are properly closed.
