Abstract
Description
Die Erfindung bezieht sich auf ein Feldgerät der Prozessautomatisierung. Bei dem Feldgerät handelt es sich beispielsweise um ein Messgerät, einen Aktor, ein Datenaufzeichnungsgerät oder um eine Anzeigeinheit.The The invention relates to a field device of process automation. In the field device For example, it is a measuring device, an actuator, a data recorder or a display unit.
Feldgeräte der modernen Prozess- und Automatisierungstechnik erfordern üblicherweise eine Vorortbedienung, bei welcher beispielsweise Drucktasten zur Eingabe von Daten oder zur Steuerung der Geräte verwendet werden. Je nach dem Anwendungsgebiet sind auch entsprechende Schutzarten zu beachten. Im Stand der Technik sind beispielsweise Folientastaturen, kapazitive Tastaturen, magnetische Tastaturen oder optische Tastaturen über die Anwendung von Reflexion bzw. Lichtschranken bekannt.Field devices of the modern Process and automation usually require on-site operation, in which, for example, push buttons for entering data or for controlling the devices be used. Depending on the field of application are also appropriate Degree of protection must be observed. For example, in the prior art Membrane keyboards, capacitive keyboards, magnetic keyboards or optical keyboards over the application of reflection or photocells known.
Der Erfindung liegt die Aufgabe zugrunde, eine alternative Möglichkeit zur Bedienung eines Feldgerätes vorzuschlagen.Of the Invention is based on the object, an alternative possibility for operating a field device propose.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass mindestens ein Sensorelement vorgesehen ist, welches ausgehend von mindestens einem auf das Sensorelement auftreffenden optischen Signal mindestens ein Steuerungssignal zur Bedienung des Feldgerätes erzeugt. Das optische Signal wird dabei vorzugsweise von einer vom Feldgerät abgesetzten und vorzugsweise selbständigen Einheit erzeugt. Dadurch lässt sich im Vergleich zu den im Stand der Technik bekannten optischen Tasten die erforderliche Energie z. B. für die Lichtschranken beim Feldgerät einsparen. Weiterhin ist eine Bedienung auch durch ein Glas hindurch möglich. Gleichzeitig findet durch die Bedienung der Tastatur keine Beeinflussung des Feldgerätes in Bezug auf Dichtigkeit statt. Im erfindungsgemäßen Feldgerät befindet sich somit ein Sensorelement, welches in dem Fall, dass es ein optisches Signal empfängt, ein Steuersignal erzeugt. Bei dem Sensorelement handelt es sich somit beispielsweise um eine Photodiode oder allgemein um eine Photozelle.The The object is achieved in that at least one sensor element is provided, which starting from at least one incident on the sensor element optical signal generates at least one control signal for operating the field device. The optical signal is preferably from a remote from the field device and preferably self-employed Unit generated. By doing so leaves in comparison to the known in the art optical Keys the required energy z. B. save for the photocells in the field device. Furthermore, an operation is also possible through a glass. simultaneously does not affect the operation of the keyboard field device in terms of tightness instead. In the field device according to the invention is thus a sensor element, which in the case that it receives an optical signal, a Control signal generated. The sensor element is thus for example, a photodiode or generally a photocell.
Eine Ausgestaltung sieht vor, dass mindestens eine Elektronikeinheit vorgesehen ist, welche mindestens durch das Steuerungssignal bedienbar ist.A Embodiment provides that at least one electronic unit is provided, which is operable at least by the control signal.
Eine Ausgestaltung beinhaltet, dass das Sensorelement in Abhängigkeit von der Frequenz des optischen Signals das Steuerungssignal erzeugt. Durch die Auswahl der Frequenz und/oder eines Frequenzbandes lässt sich beispielsweise realisieren, dass die Bedienung nur durch eine spezielle Lichtquelle möglich ist. Bei unpassenden Frequenzen findet somit beispielsweise keine unerwünschte bzw. unerlaubte Bedienung des Feldgerätes statt. Weiterhin werden in einer Ausgestaltung über die Frequenz des optischen Signals jeweils unterschiedliche Steuersignale erzeugt, so dass über ein Sensorelement unterschiedliche Bedienungen vorgenommen werden.A Embodiment includes that the sensor element in dependence from the frequency of the optical signal generates the control signal. By the selection of the frequency and / or a frequency band can be For example, realize that the operation only by a special Light source possible is. For inappropriate frequencies thus, for example, no undesirable or unauthorized operation of the field device instead. Continue to be in an embodiment about the frequency of the optical signal respectively different control signals generated, so over a sensor element different operations are made.
Eine Ausgestaltung sieht vor, dass mindestens ein vom Feldgerät abgesetztes Steuerungselement vorgesehen ist, welches mindestens ein optisches Signal erzeugt, dessen Auftreffen auf das Sensorelement dazu führt, dass das Sensorelement das Steuerungssignal erzeugt. Das Steuerungselement ist somit eine Lichtquelle, welche sich vom Feldgerät entfernen lässt und insbesondere räumlich davon getrennt ist.A Embodiment provides that at least one remote from the field device Control element is provided which at least one optical Signal generated, the impact of which on the sensor element causes that the sensor element generates the control signal. The control element is thus a light source, which can be removed from the field device and especially spatially is separated from it.
Eine Ausgestaltung beinhaltet, dass das Steuerungselement in der Art eines Laserpointers ausgestaltet ist.A Embodiment includes that the control element in the Art a laser pointer is designed.
Eine Ausgestaltung sieht vor, dass mindestens eine Anzeigeeinheit zur Darstellung von Daten vorgesehen ist.A Embodiment provides that at least one display unit for Representation of data is provided.
Eine Ausgestaltung beinhaltet, dass mindestens eine Sensoreinheit zur Bestimmung und/oder Überwachung mindestens einer Prozessgröße vorgesehen ist.A Embodiment includes that at least one sensor unit for Determination and / or monitoring provided at least one process variable is.
Eine Ausgestaltung sieht vor, dass mindestens drei Sensorelemente vorgesehen sind, welche jeweils ein ihnen zugeordnetes Steuerungssignal erzeugen. In dieser Ausgestaltung werden somit die üblichen drei Tasten: Plus, Minus und Bestätigen realisiert.A Embodiment provides that at least three sensor elements provided are each generating a control signal associated therewith. In this embodiment, therefore, the usual three buttons: Plus, Minus and confirm realized.
