Definitions
- Image detector systems and image detectors for securing images attached to walls are known per se. These can be mechanical contacts that respond when trying to take a picture away. There are also capacitive image detectors in which active electrodes are generally hidden in the wall, a counterelectrode being located at the appropriate place on the image. Removal of the image causes a change in capacity, which is detected by the image reporting system and leads to an alarm. With mechanical contact, you are bound to various specifications of this facility when hanging the pictures. Capacitive image detectors, which should be as sensitive as possible, often lead to a false alarm if the viewer approaches too closely.
- the object of the invention is to provide an image detector system in which the disadvantages described above can be avoided and which operates on completely different principles.
- an image detector system which is characterized in that electrical, insulated conductors are arranged in the wall area in a matrix-like manner, to which selectively controllable transmit and receive sensors are connected in the intersection area, that at least one electronic circuit with a receive and transmitting device is arranged in the detection area of a sensor that the electronic circuit is activated by the assigned sensor and is caused to emit a specific response signal that all electrical conductors are on a control and evaluation device are connected, which regularly polls the electrical circuits, and that an alarm message is given if there is no response signal.
- electrical, insulated wires are arranged in the wall area in rows and columns, which are at a certain distance from one another, transmission and reception sensors being connected to the wires in a respective crossing area of a row and a column.
- At least one electronic circuit with a receiving and transmitting device adapted to the sensor is invisibly arranged on the image in such a way that it is located in the detection range of a sensor.
- Each of the electrical sensors activates the associated electronic circuit and causes it to emit a specific response signal.
- All electrical conductors, i.e. the row and column wires are connected to a control and evaluation device which interrogates the electrical circuits regularly, for example in a multiplexing process, with a failure to take an alarm message due to the removal or displacement of an image of the response signal.
- each of the existing electrical circuits of a wall is expediently detected by the control and evaluation device in an initialization phase and the presence of the circuit is stored on the basis of a response signal. There is therefore no electrical circuit for sensors that do not receive a response signal. The presence of the registered electrical circuits is then checked regularly with a cyclical query.
- control and evaluation device for the image reporting system can be simple but user-specific, the control and evaluation device being correspondingly programmable by means of a connected personal computer.
- the electronic circuits can be small, extremely flat integrated circuits, that is to say microchips, which are semi-active and are stimulated to emit a specific code on the basis of the query.
- a very advantageous and expedient embodiment of the invention is that the signal transmission between the transmitting and receiving sensors and the electrical circuits takes place by inductive means, both for the transmitting and receiving sensors and for the receiving and transmitting device or antenna electronic circuit induction coils are provided.
- inductive means both for the transmitting and receiving sensors and for the receiving and transmitting device or antenna electronic circuit induction coils are provided.
- no separate voltage source is advantageously required for the electronic circuit, since the chip obtains the energy required for sending the response signal from the induction field. If necessary, however, a separate energy source can also be provided for each chip.
- the entire wall area with electronic conductors and the sensors connected to them is provided for free assignment of the pictures and thus for various possibilities of picture hangings.
- only certain wall areas can also be provided with conductors or only the required sensors can be connected to the conductors, ie only for as many sensors as are necessary if a specific picture hanging is desired.
- the column and row wires with the sensors to be assigned can be inserted or applied to or on existing walls both when erecting the corresponding walls for the images and subsequently.
- the inconspicuous wires and sensors - if they are only attached to the wall - can only be overtapped.
- Such an arrangement is particularly suitable for free partition walls, which are expediently provided for traveling exhibitions.
- the electronic circuit or chip can be arranged on the picture frame and / or on the back of the picture, but several chips can also be arranged on the back of the picture for larger pictures. With an arrangement in the picture frame, the cutting out of the picture may not be detected.
- the image detector system described above can also be used for signal transmission with another transmission means, e.g. Radio frequency energy, work.
- the conductors are then expediently shielded and small RF antennas are connected to the crossing areas.
- the semi-active chip will also have a corresponding RF antenna.
- a possible embodiment of the image detector system according to the invention is shown in principle on a figure.
- the wall area WB intended for the picture suspension is provided with electrical conductors arranged in rows ZE and columns SP at predetermined intervals, all conductors leading to a control and evaluation device SAE.
- small flat induction coils S are arranged as transmit and receive sensors S either at all points or only at certain points in this exemplary embodiment.
- An image B to be secured which is shown here to the right of the wall area WB, has at least one electronic circuit IC with a connected receiving and transmitting coil ES, which is arranged, for example, on the rear side of the image B and generally also when the Image can be detected by at least one sensor S.
- the identifier can be stored in an EE-PROM in the chip.
- the chip IC switches over and emits its identifier, which is received by the sensor or the induction coil S and is controlled via the column and row wire SP / ZE - and evaluation device SAE is directed. This emits an alarm signal AL if it does not receive a response signal when queried for a chip registered as being present.
- a personal computer PC can be connected to the control and evaluation device SAE, with which this control and evaluation device can be programmed.

Description
Bildmeldersysteme und Bildmelder zur Sicherung von an Wänden angehängten Bildern sind an sich bekannt. Das können mechanische Kontakte sein, die beim Versuch, ein Bild wegzunehmen, ansprechen. Es gibt auch kapazitive Bildmelder, bei denen im allgemeinen in der Wand verborgen aktive Elektroden angeordnet sind, wobei an dem Bild sich an entsprechender Stelle eine Gegenelektrode befindet. Eine Wegnahme des Bildes verursacht eine Kapazitätsänderung, die von dem Bildmeldesystem detektiert wird und zu einer Alarmgabe führt. Bei der mechanischen Kontaktgabe ist man beim Aufhängen der Bilder an verschiedene Vorgaben dieser Einrichtung gebunden. Kapazitive Bildmelder, die möglichst empfindlich sein sollen, führen oftmals schon bei zu großer Annäherung seitens des Betrachters zu einer Fehlalarmmeldung.Image detector systems and image detectors for securing images attached to walls are known per se. These can be mechanical contacts that respond when trying to take a picture away. There are also capacitive image detectors in which active electrodes are generally hidden in the wall, a counterelectrode being located at the appropriate place on the image. Removal of the image causes a change in capacity, which is detected by the image reporting system and leads to an alarm. With mechanical contact, you are bound to various specifications of this facility when hanging the pictures. Capacitive image detectors, which should be as sensitive as possible, often lead to a false alarm if the viewer approaches too closely.
Aufgabe der Erfindung ist es, ein Bildmeldersystem zu schaffen, bei dem oben geschilderte Nachteile vermieden werden können und welches nach völlig anderen Prinzipien arbeitet.The object of the invention is to provide an image detector system in which the disadvantages described above can be avoided and which operates on completely different principles.
Diese Aufgabe wird mit einem Bildmeldersystem gelöst, welches sich dadurch auszeichnet, daß im Wandbereich matrixartig elektrische, isolierte Leiter angeordnet sind, an denen im Kreuzungsbereich gezielt ansteuerbare Sende- und Empfangs-Sensoren angeschlossen sind, daß am Bild zumindest ein elektronischer Schaltkreis mit einer Empfangs- und Sendeeinrichtung im Erfassungsbereich eines Sensors angeordnet ist, daß der elektronische Schaltkreis von dem zugeordneten Sensor aktiviert und zur Abgabe eines spezifischen Antwortsignals veranlaßt wird, daß sämtliche elektrische Leiter an einer Steuer- und Auswerteeinrichtung angeschlossen sind, die regelmäßig die elektrischen Schaltkreise abfragt, und daß beim Ausbleiben eines Antwortsignals eine Alarmmeldung abgegeben wird.This object is achieved with an image detector system which is characterized in that electrical, insulated conductors are arranged in the wall area in a matrix-like manner, to which selectively controllable transmit and receive sensors are connected in the intersection area, that at least one electronic circuit with a receive and transmitting device is arranged in the detection area of a sensor that the electronic circuit is activated by the assigned sensor and is caused to emit a specific response signal that all electrical conductors are on a control and evaluation device are connected, which regularly polls the electrical circuits, and that an alarm message is given if there is no response signal.
Bei dem erfindungsgemäßen Bildmeldersystem sind im Wandbereich in Zeilen und Spalten elektrische, isolierte Drähte angeordnet, die zueinander einen bestimmten Abstand aufweisen, wobei in einem jeweiligen Kreuzungsbereich einer Zeile und einer Spalte Sende- und Empfangssensoren an den Drähten angeschlossen sind. Am Bild ist unsichtbar zumindest ein elektronischer Schaltkreis mit einer dem Sensor angepaßten Empfangs- und Sendeeinrichtung derart angeordnet, daß sie sich im Erfassungsbereich eines Sensors befindet. Jeder der elektrischen Sensoren aktiviert den zugehörigen elektronischen Schaltkreis und veranlaßt ihn zur Abgabe eines spezifischen Antwortsignals. Dazu sind sämtliche elektrischen Leiter, d.h. die Zeilen- und Spaltendrähte, an einer Steuer- und Auswerteeinrichtung angeschlossen, die regelmäßig, beispielsweise in einem Multiplexverfahren, die elektrischen Schaltkreise abfragt, wobei ein Ausbleiben, aufgrund der Wegnahme oder des Verschiebens eines Bildes des Antwortsignals zu einer Alarmmeldung führt.In the image detector system according to the invention, electrical, insulated wires are arranged in the wall area in rows and columns, which are at a certain distance from one another, transmission and reception sensors being connected to the wires in a respective crossing area of a row and a column. At least one electronic circuit with a receiving and transmitting device adapted to the sensor is invisibly arranged on the image in such a way that it is located in the detection range of a sensor. Each of the electrical sensors activates the associated electronic circuit and causes it to emit a specific response signal. All electrical conductors, i.e. the row and column wires are connected to a control and evaluation device which interrogates the electrical circuits regularly, for example in a multiplexing process, with a failure to take an alarm message due to the removal or displacement of an image of the response signal.
Zweckmäßigerweise wird bei dem erfindungsgemäßen Bildmeldersystem in einer Initialisierungsphase jeder der vorhandenen elektrischen Schaltkreise einer Wand von der Steuer- und Auswerteeinrichtung erfaßt und aufgrund eines Antwortsignals das Vorhandensein des Schaltkreises gespeichert. Fur Sensoren, die kein Antwortsignal erhalten, ist somit kein elektrischer Schaltkreis vorhanden. Anschließend wird mit einer zyklischen Abfrage regelmäßig das Vorhandensein der registrierten elektrischen Schaltkreise überprüft.In the image detector system according to the invention, each of the existing electrical circuits of a wall is expediently detected by the control and evaluation device in an initialization phase and the presence of the circuit is stored on the basis of a response signal. There is therefore no electrical circuit for sensors that do not receive a response signal. The presence of the registered electrical circuits is then checked regularly with a cyclical query.
In einer zweckmäßigen Ausgestaltung der Erfindung kann die Steuer- und Auswerteeinrichtung für das Bildmeldesystem einfach aber anwenderspezifisch aufgebaut sein, wobei mittels eines angeschlossenen Personalcomputers die Steuer- und Auswerteeinrichtung entsprechend programmierbar ist.In an expedient embodiment of the invention, the control and evaluation device for the image reporting system can be simple but user-specific, the control and evaluation device being correspondingly programmable by means of a connected personal computer.
Die elektronischen Schaltkreise können kleine, äußerst flache integrierte Schaltkreise, also Mikrochips, sein, die halbaktiv sind und aufgrund der Abfrage angeregt werden, einen bestimmten Code abzugeben.The electronic circuits can be small, extremely flat integrated circuits, that is to say microchips, which are semi-active and are stimulated to emit a specific code on the basis of the query.
Eine sehr vorteilhafte und zweckmäßige Ausgestaltung der Erfindung besteht darin, daß die Signalübertragung zwischen den Sende- und Empfangssensoren und den elektrischen Schaltkreisen auf induktivem Weg erfolgt, wobei sowohl für die Sende- und Empfangssensoren als auch für die Empfangs- und Sendeeinrichtung bzw. -Antenne des elektronischen Schaltkreises Induktionsspulen vorgesehen sind. Dabei ist in vorteilhafter Weise für den elektronischen Schaltkreis keine eigene Spannungsquelle erforderlich, da der Chip die zum Senden des Antwortsignals erforderliche Energie aus dem Induktionsfeld bezieht. Es können aber auch erforderlichenfalls für jeden Chip eine eigene Energiequelle vorgesehen sein.A very advantageous and expedient embodiment of the invention is that the signal transmission between the transmitting and receiving sensors and the electrical circuits takes place by inductive means, both for the transmitting and receiving sensors and for the receiving and transmitting device or antenna electronic circuit induction coils are provided. In this case, no separate voltage source is advantageously required for the electronic circuit, since the chip obtains the energy required for sending the response signal from the induction field. If necessary, however, a separate energy source can also be provided for each chip.
Für eine freie Zuordnung der Bilder und damit für verschiedene Möglichkeiten der Bildhängungen ist der gesamte Wandbereich mit elektronischen Leitern und den daran angeschlossenen Sensoren vorgesehen. Es können aber auch nur bestimmte Wandbereiche mit Leitern versehen sein bzw. nur die erforderlichen Sensoren an den Leitern angeschlossen sein, d.h. nur für soviel Sensoren als nötig, wenn eine bestimmte Bilderhängung gewünscht ist.The entire wall area with electronic conductors and the sensors connected to them is provided for free assignment of the pictures and thus for various possibilities of picture hangings. However, only certain wall areas can also be provided with conductors or only the required sensors can be connected to the conductors, ie only for as many sensors as are necessary if a specific picture hanging is desired.
Bei diesem erfindungsgemäßen Bildmeldersystem können die Spalten- und Zeilendrähte mit den zuzuordnenden Sensoren sowohl beim Errichten der entsprechenden Wände für die Bilder als auch nachträglich in bzw. auf bereits vorhandene Wände ein- bzw. aufgebracht werden. Die unscheinbaren Drähte und Sensoren können - wenn sie nur auf der Wand aufgebracht sind - im einfachsten Fall nur übertapeziert sein. Eine derartige Anordnung eignet sich besonders für freie Stellwände, die für Wanderausstellungen zweckmäßigerweise vorgesehen sind.In this image detector system according to the invention, the column and row wires with the sensors to be assigned can be inserted or applied to or on existing walls both when erecting the corresponding walls for the images and subsequently. In the simplest case, the inconspicuous wires and sensors - if they are only attached to the wall - can only be overtapped. Such an arrangement is particularly suitable for free partition walls, which are expediently provided for traveling exhibitions.
Der elektronische Schaltkreis bzw. Chip kann am Bilderrahmen und/oder auf der Bildrückseite angeordnet sein, es können aber auch bei größeren Bildern mehrere Chips auf der Bildrückseite angeordnet sein. Bei einer Anordnung im Bilderrahmen kann möglicherweise das Herausschneiden des Bildes nicht detektiert werden.The electronic circuit or chip can be arranged on the picture frame and / or on the back of the picture, but several chips can also be arranged on the back of the picture for larger pictures. With an arrangement in the picture frame, the cutting out of the picture may not be detected.
Mit dem erfindungsgemäßen Bildmeldersystem können aber auch andere Objekte, die an der Wand angeordnet bzw. angebracht sind, gesichert sein, wenn das Objekt einen entsprechenden Chip aufweist.With the image detector system according to the invention, however, other objects which are arranged or attached to the wall can also be secured if the object has a corresponding chip.
Das oben geschilderte Bildmeldersystem kann für die Signalübertragung auch mit einem anderen Übertragungsmittel, z.B. Hochfrequenzenergie, arbeiten. Zweckmäßigerweise wird man dann die Leiter geschirmt ausbilden und an den Kreuzungsbereichen kleine HF-Antennen anschließen. Ebenso wird der halbaktive Chip eine entsprechende HF-Antenne aufweisen.The image detector system described above can also be used for signal transmission with another transmission means, e.g. Radio frequency energy, work. The conductors are then expediently shielded and small RF antennas are connected to the crossing areas. The semi-active chip will also have a corresponding RF antenna.
Ein mögliches Ausführungsbeispiel für das erfindungsgemäße Bildmeldersystem ist prinzipiell an einer Figur dargestellt.A possible embodiment of the image detector system according to the invention is shown in principle on a figure.
Der für die Bildaufhängung vorgesehene Wandbereich WB ist mit elektrischen Leitern versehen, die in Zeilen ZE und Spalten SP in vorgegebenen Abständen angeordnet sind, wobei sämtliche Leiter, auf eine Steuer- und Auswerteeinrichtung SAE führen. Im Bereich des Schnittpunktes der Zeilen- und Spaltendrähte sind entweder an allen Punkten oder nur an bestimmten Punkten in diesem Ausführungsbeispiel als Sende- und Empfangssensoren S kleine flache Induktionsspulen angeordnet. Ein zu sicherndes Bild B, das hier rechts vom Wandbereich WB dargestellt ist, weist zumindest eine elektronische Schaltung IC mit einer angeschlossenen Empfangs- und sendespule ES auf, die beispielsweise auf der Rückseite des Bildes B angeordnet ist und im allgemeinen auch bei einem freizügigen Aufhängen des Bildes von mindestens einem Sensor S erfaßt werden kann. Im Chip kann die Kennung in einem EE-PROM abgespeichert sein. Sobald die Empfangs- und sendespule ES des Chips IC die Anregungsenergie vom Sender S empfängt, schaltet der Chip IC Senden um und strahlt seine Kennung ab, die vom Sensor bzw. der Induktionsspule S empfangen und über den Spalten- und Zeilendraht SP/ZE zur Steuer- und Auswerteeinrichtung SAE geleitet wird. Diese gibt ein Alarmsignal AL ab, wenn sie bei der Abfrage für einen als Vorhanden registrierten Chip kein Antwortsignal erhält. Wie bereits erwähnt, ist an der Steuer- und Auswerteeinrichtung SAE ein Personalcomputer PC anschließbar, mit dem diese Steuer- und Auswerteeinrichtung programmierbar ist. Mit dem erfindungsgemäßen Bildmeldersystem werden die Bilder sowohl auf Wegnahme als auch auf ein Verschieben überwacht, weil das System auch erkennt, wenn sich die Lage des Bildes verändert hat.The wall area WB intended for the picture suspension is provided with electrical conductors arranged in rows ZE and columns SP at predetermined intervals, all conductors leading to a control and evaluation device SAE. In the area of the intersection of the row and column wires, small flat induction coils S are arranged as transmit and receive sensors S either at all points or only at certain points in this exemplary embodiment. An image B to be secured, which is shown here to the right of the wall area WB, has at least one electronic circuit IC with a connected receiving and transmitting coil ES, which is arranged, for example, on the rear side of the image B and generally also when the Image can be detected by at least one sensor S. The identifier can be stored in an EE-PROM in the chip. As soon as the receiving and transmitting coil ES of the chip IC receives the excitation energy from the transmitter S, the chip IC switches over and emits its identifier, which is received by the sensor or the induction coil S and is controlled via the column and row wire SP / ZE - and evaluation device SAE is directed. This emits an alarm signal AL if it does not receive a response signal when queried for a chip registered as being present. As already mentioned, a personal computer PC can be connected to the control and evaluation device SAE, with which this control and evaluation device can be programmed. With the image detector system according to the invention, the images are monitored both for removal and for displacement, because the system also recognizes when the position of the image has changed.
