Description

Die Erfindung betrifft eine Überwachungsvorrichtung mit einer Vorderwand aus insbesondere schwarzem, für sichtbares Licht undurchlässigem Kunststoff, der für Infrarotstrahlen durchlässig ist und hinter dem eine Infrarotkamera und eine Infrarotleuchte angeordnet sind.The invention relates to a monitoring device with a front wall made, in particular, of black plastic which is opaque to visible light, which is transparent to infrared rays and behind which an infrared camera and an infrared lamp are arranged.

Solche Überwachungsvorrichtungen sind bekannt. Es ist auch bekannt, diese Überwachungsvorrichtungen als Außenstation mit einer Zentralstation zu verbinden. Diese Überwachungsvorrichtungen haben sich bewährt. Tag und Nacht ist eine Observierung, unabhängig von fremder Beleuchtung, möglich.Such monitoring devices are known. It is also known to connect these monitoring devices as a remote station to a central station. These monitoring devices have proven themselves. Observation is possible day and night, regardless of external lighting.

Der Erfindung liegt die Aufgabe zugrunde, den Einsatzbereich insofern zu verbessern, als eine Aversion gegenüber solchen Überwachungsvorrichtungen beseitigt, darüber hinaus aber auch eine Ausführung geschaffen wird, die von der Überwachungsvorrichtung fortführt und eine Ausgestaltung schafft, die vergessen läßt, daß ein die Vorrichtung verwirklichender Gegenstand eine Überwachungsvorrichtung ist.The invention has for its object to improve the field of application in that an aversion to such monitoring devices is eliminated, but moreover an embodiment is created that continues from the monitoring device and creates a configuration that makes it possible to forget that an object realizing the device is a monitoring device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorderwand in Form eines Deckblattes als Ziffernanzeige für eine Uhr ausgeführt ist, deren Zahlenmarkierungen an der Vorderseite des Deckblattes sichtbar auftreten. Das Deckblatt läßt entsprechend der Vorderwand Infrarotstrahlen durch, während es für sichtbares Licht undurchlässig ist.This object is achieved in that the front wall is designed in the form of a cover sheet as a numerical display for a clock, the number marks of which appear visibly on the front of the cover sheet. The cover sheet transmits infrared rays according to the front wall, while it is opaque to visible light.

Durch eine solche Ausführung wird nicht nur eine zusätzliche Aufgabe von der Überwachungsvorrichtung übernommen, sondern es entstehen Erscheinungsformen, durch welche die Überwachungsvorrichtung auch noch einen anderen Zweck erfüllt.Such an embodiment not only takes on an additional task from the monitoring device, but also forms of appearance through which the monitoring device also fulfills another purpose.

Für diese Zweckerfüllung, die an sich bei dem für sichtbares Licht undurchlässigen Kunststoff überraschend ist, können die Zahlenmarkierungen in verschiedener Weise vorhanden sein. Sie können als Zahlenauftrag, als eingebettete Anzeigevorrichtung, insbesondere auch für Segmentanzeigen vorliegen. Wesentlich ist die Ausgestaltung einer Überwachungsvorrichtung als Uhr durch besondere Ausbildung des Deckblattes als Ziffernanzeige.The number markings can be present in various ways for this purpose, which is surprising in itself with the plastic that is impermeable to visible light. They can be present as a number order, as an embedded display device, in particular also for segment displays. What is essential is the design of a monitoring device as a clock by special design of the cover sheet as a numerical display.

Unter obigen Gesichtspunkten liegt eine vorteilhafte Ausgestaltung darin, daß die Zahlenmarkierungen als Ziffernblatt an der Vorderseite des Deckblattes angeordnet sind und vor ihnen Zeiger bewegbar sind, für welche wenigstens eine Antriebsvorrichtung an der Rückseite des Deckblattes angeordnet ist. Dieses ist eine besonders einfache, aber auch in das Auge fallende und für den Einsatz günstige Ausgestaltung.From the above points of view, an advantageous embodiment is that the numerical markings are arranged as a dial on the front of the cover sheet and pointers can be moved in front of them, for which at least one drive device is arranged on the back of the cover sheet. This is a particularly simple, but also eye-catching design that is favorable for use.

In einer anderen Ausführungsform ist das Deckblatt als Aufnahme für um ein Zentrum verteilte Ziffernanzeigen in Markierungsfeldern ausgeführt, welche nach dem jeweiligen Zeitpunkt ansteuerbar sind und Zahlenangaben liefern. Die Ansteuerbarkeit bringt zum Ausdruck, daß es nicht auf die Anordnung eines Zeigers ankommt, sondern daß die Zeitmarkierungen beispielsweise aufleuchtenIn another embodiment, the cover sheet is designed as a receptacle for numerical displays distributed around a center in marking fields, which can be activated at the respective time and provide numerical information. The controllability expresses the fact that the arrangement of a pointer is not important, but that the time markers light up, for example

Auch unter diesem Gesichtspunkt besteht eine vorteilhafte Ausgestaltung darin, daß die Vorderwand mit mehreren, insbesondere Mehr-Segmentanzeigevorrichtungen ausgestattet ist, die zeitabhängig ansteuerbar sind. Hierbei kann die Eigenschaft als Uhr in besonders günstiger Weise verwirklicht werden.From this point of view, too, there is an advantageous embodiment in that the front wall is equipped with a plurality of, in particular multi-segment, display devices which can be controlled as a function of time. Here, the property as a clock can be realized in a particularly favorable manner.

Es versteht sich, daß in einer weiteren Ausgestaltung, daß das Deckblatt ein Feld für eine Ziffernanzeige aufweist,
in welchem die jeweilige Uhrzeit anzeigbar ist. Dieses Feld kann auch am Rand des Deckblatts angeordnet sein.
It goes without saying that in a further embodiment that the cover sheet has a field for a numerical display,
in which the respective time can be displayed. This field can also be arranged on the edge of the cover page.

Die Erfindung wird im folgenden anhand vorteilhafter Ausführungsbeispiele erläutert, die in der Zeichnung dargestellt sind. In dieser zeigen:

Fig. 1
eine teilweise im Schnitt dargestellte Seitenansicht eines Gehäuses der erfindungsgemäßen Überwachungsvorrichtung mit den wesentlichen eingebrachten Teilen;
Fig. 2
eine Stirnansicht von Figur 1 von links gesehen in einer Ausführungsform;
Fig. 3
eine Stirnansicht von Figur 1 von links gesehen in einer anderen Ausführungsform.
The invention is explained below on the basis of advantageous exemplary embodiments which are illustrated in the drawing. In this show:
Fig. 1
a partially sectioned side view of a housing of the monitoring device according to the invention with the essential parts;
Fig. 2
a front view of Figure 1 seen from the left in one embodiment;
Fig. 3
a front view of Figure 1 seen from the left in another embodiment.

In allen Figuren, die für die Erfindung nicht beschränkend sind, sind gleiche Teile mit gleichen Bezugszeichen bezeichnet.In all figures, which are not restrictive to the invention, the same parts are designated by the same reference numerals.

Nach Fig. 1 hat ein Gehäuse 1, das mit Anschlußmitteln 2 zur Verbindung mit anderen Auswertvorrichtungen oder Energieeinspeisungen mit einem Kabelanschluß 3 versehen ist, eine Vorderwand 4. Diese erscheint schwarz. Sie besteht aus einem speziellen Grundstoffmaterial, das für sichtbares Licht undurchlässig ist, jedoch für IR-Strahlen durchlässig. Insofern sind auch innerhalb des Gehäuses ein Infrarotsender 5 mit einem Sendegerät 6 und ein Infrarotempfänger 7, beispielsweise als Infrarotkamera 8 mit einem Aufnahmeteil angeordnet. Dabei ist es von Bedeutung, daß nicht nur der Infrarotsender 5 vorgesehen ist, welcher eine Infrarotlichtquelle darstellt, sondern daß in diesem Zusammenhang die Teile 5 bis 8 reflektionsfrei angeordnet sind und Tag und Nacht arbeiten.1 has a housing 1, which is provided with connection means 2 for connection to other evaluation devices or energy feeds with a cable connection 3, a front wall 4. This appears black. It consists of a special base material that is opaque to visible light, but permeable to IR rays. In this respect, an infrared transmitter 5 with a transmitter 6 and an infrared receiver 7, for example as an infrared camera 8 with a receiving part, are also arranged within the housing. It is important that not only the infrared transmitter 5 is provided, which represents an infrared light source, but that in this connection the parts 5 to 8 are arranged without reflection and work day and night.

Solche Ausführungen sind im wesentlichen bekannt. Sie zeigen aber eine Vorderwand 4 mit ganz speziellen Eigenschaften, welche nämlich eine Überwachung von der Rückseite her zulassen, aber von der Vorderseite einen besonderen Einsatz ermöglichen.Such designs are essentially known. However, they show a front wall 4 with very special properties, which allow monitoring from the rear, but allow a special use from the front.

Aus diesem Grunde wird die Ausgestaltung der Vorderwand als Ziffernanzeige beansprucht. Der Ausdruck Ziffernanzeige beinhaltet in einer Ausführung wenigstens eines Zeigers an der Vorderplatte, insbesondere Vorderwand der die Frontplatte bildenden Scheibe mit den oben angegebenen Eigenschaften einer Undurchlässigkeit für sichtbares Licht, aber Durchlässigkeit für Infrarotstrahlen und letzten Endes auch als Haltebaugruppe für zusätzliche Teile, wie Leuchte, Kamera etc.For this reason, the design of the front wall as a numerical display is claimed. In one embodiment, the term numerical display includes at least one pointer on the front plate, in particular the front wall of the pane forming the front plate, with the above-mentioned properties of an opacity for visible light, but permeability for infrared rays and ultimately also as a holding assembly for additional parts, such as a lamp or camera Etc.

Aus Figur 2 ist eine Zeigeranordnung 10 erkennbar mit wenigstens einem umlaufenden Zeiger 11, gegebenenfalls auch wenigstens einem zugeordneten Zeiger 12, die nach Art eines Stunden-und Minutenzeigers umlaufen und denen ein Kranz 13 von Zeitmarkierungen zugeordnet ist.FIG. 2 shows a pointer arrangement 10 with at least one revolving pointer 11, possibly also at least one assigned pointer 12, which revolve in the manner of an hour and minute hand and to which a ring 13 of time markings is assigned.

Die Ansicht nach Figur 3 zeigt eine Vorderseite 9 mit einem rechteckigen Rand, wobei in der Vorderseite, welche von der Vorderwand des Deckblattes gebildet ist, Markierungsfelder 14 bis 16 ..., 17, 18 angeordnet sind, in denen Ziffernanzeigen zur Ausleuchtung gebracht werden können. Solche Ziffern-anzeigen können nach Figur 1 durch eine elektronische Steueranordnung 19 auslösbar sein, um dadurch unter Auswertung empfangener Signale, und zwar unter Auswertung von Signalen, die aufgrund der Infrarotlichtquellen ausgesandt und von der Kamera aufgenommen werden, eine besondere Markierung auch für die Zeitanzeige zu hinterlegen. Dieses kann in den Feldern 14 bis 18 dadurch geschehen, daß sich der Hintergrund in Abhängigkeit von den empfangenen Signalen verschieden färbt.The view according to FIG. 3 shows a front side 9 with a rectangular edge, marking fields 14 to 16... 17, 18 being arranged in the front side, which is formed by the front wall of the cover sheet, in which numerical displays can be illuminated . Such numerical displays can, according to FIG. 1, be triggered by an electronic control arrangement 19 in order to thereby also provide a special marking for the time display by evaluating received signals, specifically by evaluating signals that are emitted due to the infrared light sources and recorded by the camera deposit. This can be done in fields 14 to 18 in that the background is colored differently depending on the signals received.

Eine solche Ausführung hat bestimmte Vorteile für einen speziellen Einsatz. Es versteht sich, daß aber bei Anordnung der Ziffernanzeige in erster Linie nur beabsichtigt ist, die jeweilige Uhrzeit mitanzugeben. Dieses hat für die Überwachungsvorrichtung schon deshalb Vorteile, weil das jeweils durch die Kamera 8 aufgenommene Bild mit einer Uhrzeitmarkierung versehen werden kann. Der Vorteil liegt aber weitergehend darin, daß die Vorrichtung insgesamt nur als Uhr und nicht als Überwachungsvorrichtung erkennbar ist.Such a design has certain advantages for a special application. It goes without saying that when the numerical display is arranged, the primary intention is only to indicate the respective time. This has advantages for the monitoring device if only because the image recorded by the camera 8 can be provided with a time marker. The advantage is, however, that the device can only be recognized as a clock and not as a monitoring device.

Unter letztem Gesichtspunkt ist auch gegenüber der Figur 3 durchaus einbezogen, nur ein Sichtfeld nach Art einer Digitaluhr anzuordnen, in welcher die jeweilige Zeit mit ziffernmäßiger Anzeige abläuft.From the last point of view, it is also included with respect to FIG. 3 to arrange only one field of view in the manner of a digital clock, in which the respective time runs with a numerical display.

In den Figuren ist jeweils 4 als Vorderwand dargestellt. Diese Vorderwand bildet mit ihrer Vorderseite das Deckblatt 20, auf welchem Markierungen angeordnet oder in welches Markierungen oder Sichtfelder eingelassen sind und vor welchem gegebenenfalls Zeiger bewegbar sind.In the figures, 4 is shown as the front wall. This front wall forms with its front side the cover sheet 20, on which markings are arranged or in which markings or fields of vision are embedded and in front of which pointers can be moved if necessary.

In der Ausführung des Deckblattes als Uhr wird einbezogen, daß an der Vorderwand 4 Mehr-Segmentanzeigevorrichtungen angeordnet sind, die in diesem Fall auch wegen ihrer Anordnung mit 14 bis 18 bezeichnet sind und die jeweils auch im Hinblick auf ihre Umfangsanordnung die jeweilige Zeit in ziffernmäßiger Anzeige liefern.In the design of the cover page as a clock is included that 4 multi-segment display devices are arranged on the front wall, which in this case are also designated because of their arrangement with 14 to 18 and each also with regard to their circumferential arrangement the respective time in numerical display deliver.
