Description

La présente invention concerne d'une manière générale les systèmes de sécurité contrôlant le déplacement d'objets et le transport illicite de ceux-ci à l'extérieur d'une enceinte, et plus particulièrement les dispositifs de marquage, par exemple sous forme d'étiquettes, des objets devant être surveillés.The present invention relates generally to security systems controlling the movement of objects and the illegal transport of these outside a enclosure, and more particularly the marking, for example in the form of labels, of objects to be monitored.

La plupart des systèmes de sécurité mis en oeuvre à l'heure actuelle utilisent des dispositifs de marquage qui sont détectés au moment de leur passage dans des zones de contrôle. Ce type de système est couramment utilisé dans les magasins où les articles en vente sont munis d'étiquettes dont la présence est détectée lors du passage entre des antennes disposées le long des différents passages de sortie, y compris près des caisses.Most security systems implemented by the hour current use marking devices that are detected at the time of their passage in areas of control. This type of system is commonly used in stores where items for sale are provided of labels whose presence is detected during the passage between antennas arranged along the different exit passages, including near cash desks.

Ces systèmes ne sont pas totalement infaillibles puisqu'il suffit de détacher l'étiquette de l'article avant de sortir du magasin pour que l'article dérobé ne soit pas détecté.These systems are not completely foolproof since just peel off the item label before going out from the store so that the stolen item is not detected.

C'est pourquoi l'on voit apparaítre des dispositifs de marquage de plus en plus volumineux et de plus en plus complexes à détacher de l'objet qui les porte sans moyen spécifique et sans risquer de détériorer l'objet ainsi marqué.This is why we see appearing devices more and more voluminous marking and more and more complex to detach from the object that carries them without means specific and without risk of damaging the object as well Mark.

Par ailleurs, ces dispositifs de marquage conservent leurs propriétés de faire détecter l'objet qui les porte tant qu'ils n'ont pas été enlevés ce qui les rend détectables même lors d'un passage licite dans des zones de contrôle, c'est-à-dire après les avoir régulièrement obtenus. Nombreux sont ceux qui, ayant acheté un objet dans un magasin, vont dans un autre magasin où l'objet est détecté lors de leur sortie et provoque l'arrivée précipitée des services de surveillance.Furthermore, these marking devices retain their properties of detecting the object that carries them so much that they have not been removed which makes them detectable even during a lawful passage in control zones, that is to say after having obtained them regularly. Many people, having bought an object in a store, go to another store where the object is detected when they leave and causes the hasty arrival of surveillance services.

Il existe donc un besoin en ce qui concerne des dispositifs de marquage non pas passifs et ne pouvant répondre qu'au moment d'une interrogation spécifique, par exemple lors d'un passage entre des antennes de la zone de contrôle, mais actifs c'est-à-dire capables de faire savoir qu'ils sont détachés ou détruits, et destructibles lorsque leur rôle est achevé, c'est-à-dire lorsque l'objet a été régulièrement acheté.There is therefore a need for devices not passive marking and can only respond to time of a specific question, for example during a passage between antennas in the control area, but active that is to say capable of making known that they are detached or destroyed, and destructible when their role is completed, i.e. when the object has been regularly bought.

Il a été proposé dans le US 3 713 133 délivré à Robert L. Nathans un dispositif de marquage accroché à l'article par une épingle de nourrice qui, d'une part, peut être détecté par des dispositifs de surveillance lors de son passage dans une zone contrôlée de sortie et dont, d'autre part, l'ouverture en vue de son retrait de l'article est détectée par des moyens de surveillance disposés dans le magasin.It was proposed in US 3,713,133 issued to Robert L. Nathans a marking device attached to the article by a safety pin which, on the one hand, can be detected by surveillance devices during its passage in a controlled exit area and which, on the other hand, opening for removal of item is detected by monitoring means arranged in the store.

Ces dispositifs de marquage permettent une surveillance plus efficace puisqu'une alarme retentit dès qu'une personne non habilitée ouvre l'épingle de nourrice mais sont encore défaillants lorsque la personne désirant subtiliser l'objet est prête à le détériorer en partie, par exemple lorsqu'il s'agit d'un habit en pratiquant une fente permettant de retirer l'épingle sans l'ouvrir.These marking devices allow monitoring more effective since an alarm sounds as soon as a unauthorized person opens the safety pin but are still failing when the person desiring to steal the object is ready to partially deteriorate it, by example when it is a garment by practicing a slit allowing the pin to be removed without opening it.

La présente invention tend à proposer un dispositif de marquage tel qu'il ne puisse être désassemblé de l'article sur lequel il a été placé sans émettre de signal d'alarme.The present invention aims to provide a device for marking such that it cannot be disassembled from the article on which it was placed without emitting an alarm signal.

A cet effet, l'invention concerne un dispositif de marquage du type comportant un anneau de détection dont une caractéristique électrique est modifiée lorsque l'on tente de désolidariser le dispositif de l'objet qui le porte. To this end, the invention relates to a marking device of the type comprising a detection ring, one of which electrical characteristic is changed when trying to separate the device from the object carrying it.

L'invention propose un dispositif de marquage rendu particulièrement fiable par sa constitution.The invention provides a rendered marking device particularly reliable by its constitution.

Avantageusement, les dispositifs de marquage selon l'invention permettent également la gestion des objets portant lesdits dispositifs.Advantageously, the marking devices according to the invention also allow the management of objects carrying said devices.

L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :

  • la figure 1 représente de manière schématique un dispositif de marquage selon l'invention,
  • les figures 2a à 2e montrent les différentes étapes de fabrication du dispositif de marquage selon l'invention représenté à la figure 1,
  • la figure 3 représente schématiquement une variante de réalisation d'un dispositif de marquage suivant l'invention,
  • la figure 4représente schématiquement une seconde variante de réalisation du dispositif de marquage selon l'invention.
  • les figures 5 et 6 montrent deux exemples de réalisation du circuit électronique du dispositif de marquage.
The invention will be better understood thanks to the description which follows given by way of nonlimiting example with reference to the appended drawings in which:
  • FIG. 1 schematically represents a marking device according to the invention,
  • FIGS. 2a to 2e show the different stages of manufacturing the marking device according to the invention shown in FIG. 1,
  • FIG. 3 schematically represents an alternative embodiment of a marking device according to the invention,
  • Figure 4 schematically shows a second alternative embodiment of the marking device according to the invention.
  • Figures 5 and 6 show two embodiments of the electronic circuit of the marking device.

L'invention concerne un dispositif de marquage tel que celui représenté schématiquement à la figure 1 et comportant un module électronique 13 et un anneau de détection 15 d'une tentative de fraude.The invention relates to a marking device such as the one shown schematically in Figure 1 and comprising an electronic module 13 and a ring detection 15 of an attempted fraud.

Le module électronique est de toute forme appropriée aux commandes que l'on veut lui faire réaliser, il pourra comporter une ou plusieurs puces électroniques, et/ou des composants de surface. The electronic module is in any form suitable for commands that we want him to realize, he can have one or more electronic chips, and / or surface components.

Le conducteur 15 formant l'anneau de détection est un conducteur très fin pouvant facilement se rompre. Ce conducteur peut être de surface importante, mais d'épaisseur très faible afin qu'il soit déchirable.The conductor 15 forming the detection ring is a very thin conductor that can easily break. This conductor may be large in area, but very thin so that it is tearable.

De manière connue en soi, le module électronique 13 peut être alimenté par une source d'énergie telle qu'une pile. Suivant une variante de réalisation, le conducteur 15 permet également d'assurer l'alimentation du module électronique 13 en énergie électrique en soumettant le dispositif de marquage à un champ énergétique, de préférence un champ radio-électrique. Un tel champ créé dans la zone à surveiller induit dans le conducteur 15 un courant qui est redressé de manière connue en soi pour alimenter ledit module électronique.In a manner known per se, the electronic module 13 can be powered by an energy source such as a battery. According to an alternative embodiment, the conductor 15 also provides power to the module electronic 13 in electrical energy by submitting the energy field marking device, preferably a radio field. Such a field created in the area to be monitored induced in conductor 15 a current which is rectified in a manner known per se for supplying said electronic module.

Les dispositifs de marquage sont particulièrement mais non exclusivement destinés au marquage en vue de leur surveillance d'articles tels que des articles mis en vente exposés dans des magasins. Ils peuvent également être mis en oeuvre dans des musées ou autres lieux d'exposition.The marking devices are particularly but not exclusively intended for marking with a view to their monitoring items such as items for sale exposed in stores. They can also be put used in museums or other exhibition places.

Les zones à surveiller étant ainsi généralement des locaux fermés, il est très aisé d'y créer des champs radioélectriques assurant l'apport d'énergie aux dispositifs de marquage selon l'invention.The areas to be monitored are therefore generally local closed, it is very easy to create radio fields there ensuring the supply of energy to the marking according to the invention.

Dans le cas des magasins tels que les grandes surfaces, ou des lieux d'exposition, le champ créé par la multitude de dispositifs d'éclairage que l'on y trouve, peut suffire à alimenter les dispositifs de marquage selon l'invention et permettre de s'affranchir de la nécessité de produire spécialement des champs énergétiques en vue de l'alimentation desdits dispositifs de marquage.In the case of stores such as supermarkets, or exhibition places, the field created by the multitude of lighting devices found there, may be sufficient to supply the marking devices according to the invention and free from the need to produce specially energy fields for the supply of said marking devices.

En choisissant et en programmant convenablement le module électronique porté par le dispositif de marquage selon l'invention, l'on peut également faire dialoguer ledit dispositif avec un réseau de contrôle des stocks et/ou des prix. A cet effet, l'on met en oeuvre un module électronique capable de stocker des informations et d'émettre et/ou de recevoir des informations soit seul, soit par l'intermédiaire d'une antenne.By choosing and programming the module properly electronic carried by the marking device according to the invention, it is also possible to have said dialogue device with an inventory control network and / or price. To this end, a module is implemented electronic capable of storing information and to send and / or receive information either alone, either through an antenna.

Dans cette forme de réalisation, l'anneau de détection 15 est utilisé comme antenne.In this embodiment, the detection ring 15 is used as an antenna.

Les signaux numériques émis par le module électronique peuvent également être codés afin de les distinguer aisément d'autres signaux parasites extérieurs.Digital signals from the electronic module can also be coded to distinguish them easily other external spurious signals.

Le dispositif de marquage selon l'invention est destiné à être mis en oeuvre dans des locaux possédant des systèmes de surveillance du type usuellement mis en oeuvre dans les zones de contrôle de sortie, ainsi que des systèmes de surveillance destinés à repérer des tentatives de fraude dans le local même.The marking device according to the invention is intended for be implemented in premises with systems of the type usually used in exit control areas, as well as surveillance to identify fraud attempts in the room itself.

Ces tentatives de fraude sont constituées par le fait que l'on cherche à désolidariser le dispositif de marquage de l'objet qui le porte.These fraud attempts are made up of the fact that we seek to separate the marking device from the object that carries it.

Le circuit électronique porté par l'étiquette assure l'émission d'un signal dès qu'une personne non autorisée tente de désolidariser l'étiquette de l'objet qui la porte.The electronic circuit carried by the label ensures the emission of a signal as soon as an unauthorized person tries to dissociate the label from the object that wears it.

La détection de cette tentative de désolidarisation du dispositif de marquage est réalisée grâce à l'anneau de détection 15 et c'est à cet effet que le conducteur utilisé pour sa réalisation est de section très faible afin de le fragiliser, et de permettre que sa continuité électrique soit rompue dès que l'on tente de désolidariser le dispositif de marquage de l'article qui le porte.Detection of this attempt to dissociate the marking device is carried out thanks to the ring of detection 15 and it is for this purpose that the conductor used for its realization is of very small section in order to weaken, and allow its electrical continuity is broken as soon as an attempt is made to separate the device for marking the article carrying it.

Le dispositif de marquage suivant l'invention est réalisé sous la forme d'une étiquette adhésive destinée à être collée sur un article mis en vente ou en exposition. The marking device according to the invention is produced in the form of an adhesive label intended to be pasted on an article put on sale or in exhibition.

Le dispositif de marquage étant collé par toute sa surface sur l'article à protéger, il n'est pas envisageable de découper l'article pour enlever ledit dispositif afin de pouvoir subtiliser l'article ainsi démarqué car celui-ci serait trop détérioré pour être encore utilisable.The marking device being glued by its entire surface on the article to be protected, it is not possible to cut the article to remove said device in order to be able to steal the article thus unmarked because it would be too deteriorated to be still usable.

La seule manière de se procurer l'article sans risquer que celui-ci soit détecté dans les zones de contrôle est alors de décoller ladite étiquette.The only way to get the item without risking that this is detected in the control zones is then to take off said label.

Or pour ce faire, il est nécessaire de déformer ladite étiquette et de tirer sur celle-ci ce qui entraínera la coupure en un ou plusieurs points de l'anneau de détection 15.However, to do this, it is necessary to deform said label and pull on it which will cause the cut at one or more points of the detection ring 15.

Cette coupure de la continuité électrique de l'anneau de détection 15 est immédiatement décelée par le module électronique, ce qui l'amène à envoyer un signal qui est intercepté et interprété par les moyens de surveillance répartis dans le local.This cut in the electrical continuity of the ring of detection 15 is immediately detected by the module electronic, which causes it to send a signal which is intercepted and interpreted by surveillance means distributed in the room.

Le fil conducteur formant l'anneau de détection 15 peut être utilisé comme antenne d'émission de ce signal.The conducting wire forming the detection ring 15 can be used as the antenna for transmitting this signal.

Le service de surveillance est ainsi, grâce à l'étiquette, immédiatement prévenu de la tentative de fraude.The surveillance service is thus, thanks to the label, immediately notified of the attempted fraud.

Une fois le signal de tentative de fraude émis, le dispositif de marquage suivant la réalisation représentée à la figure 1 ne peut plus recevoir d'alimentation ce qui le rend muet dans le local.Once the attempted fraud signal is issued, the marking device according to the embodiment shown in Figure 1 can no longer receive power which mutes in the room.

L'on peut toutefois prévoir que le module électronique reste fixé à l'article après l'arrachage de l'étiquette et soit détectable par les systèmes de surveillance disposés dans les zones de sortie du magasin pour fournir une seconde possibilité d'intercepter le fraudeur croyant s'être débarrassé des moyens de marquage de l'article. It can however be provided that the electronic module remains attached to the article after removal of the label and either detectable by the monitoring systems arranged in store exit areas to provide second possibility to intercept the believing fraudster get rid of the means of marking the article.

A cet effet, l'étiquette est, suivant l'invention, réalisée en plusieurs couches pelables de manière à ce que l'anneau de détection 15 soit porté par une face externe de l'étiquette, il est ainsi d'une part très facilement rompu, et d'autre part enlevé de l'article portant le dispositif de marquage, tandis que le module électronique est solidarisé à l'adhésif et reste collé à l'article.To this end, the label is, according to the invention, produced in several peelable layers so that the ring detection 15 is carried by an external face of the label, on the one hand it is very easily broken, and on the other hand removed from the article carrying the device marking, while the electronic module is secured to the adhesive and remains glued to the article.

Les figures 2a à 2e montrent, à titre d'exemple non limitatif, les étapes de fabrication d'un tel dispositif.Figures 2a to 2e show, by way of example not limitative, the steps for manufacturing such a device.

Lors de la première étape représentée à la figure 2a, l'on découpe dans un ruban de matière 1 un premier flan 2 ayant globalement la forme de l'étiquette à réaliser, mais étant de préférence de dimensions inférieures.During the first step shown in Figure 2a, we cut from a material ribbon 1 a first blank 2 having overall the shape of the label to be produced, but being preferably of smaller dimensions.

Comme représenté à la figure 2b, l'un des coins dudit flan présente une découpe en L 4. Sur ce premier flan 2 l'on forme des portions métallisées conductrices 3, par exemple circulaires, disposées à proximité de la périphérie et l'on fixe un module électronique 13 sur le bord concave de la découpe 4.As shown in Figure 2b, one of the corners of said blank presents a cut in L 4. On this first blank 2 we forms conductive metallized portions 3, for example circular, arranged near the periphery and one fixes an electronic module 13 on the concave edge of the cutout 4.

Un second flan 6 est également découpé à partir du ruban de matière à l'étape représentée à la figure 2c.A second blank 6 is also cut from the ribbon of material in the step shown in Figure 2c.

Ce second flan 6 présente une découpe 8 dans le coin correspondant à celui dans lequel a été disposé le module électronique 13 sur le premier flan 2, ainsi que des ouvertures 7 disposées de manière à être en regard des portions métallisées 3 lorsque l'on dispose les deux flans 2 et 6 l'un sur l'autre comme représenté à la figure 2d.This second blank 6 has a cutout 8 in the corner corresponding to the one in which the module was placed electronics 13 on the first blank 2, as well as openings 7 arranged so as to be opposite the metallized portions 3 when the two blanks are placed 2 and 6 on top of each other as shown in Figure 2d.

Après avoir positionné les deux flans l'un sur l'autre avec les ouvertures 7 en regard des portions métallisées 3 et les avoir solidarisés par une couche adhésive, l'on forme l'anneau de détection 15 en positionnant sur le second flan 6, disposé sur le premier flan 2, des pistes conductrices que l'on raccorde aux portions métallisées 3 dudit premier flan 2, et au module électronique 13 par soudure. Le module électronique 13 et les soudures sont ensuite recouverts d'un vernis protecteur.After positioning the two blanks one on top of the other with the openings 7 opposite the metallized portions 3 and having joined them with an adhesive layer, we form the detection ring 15 by positioning on the second blank 6, arranged on the first blank 2, conductive tracks which are connected to the metallized portions 3 of said first blank 2, and to the electronic module 13 by welding. The module electronics 13 and the solders are then covered protective varnish.

L'on surmoule ensuite le module électronique 13 dans un pion 101, puis l'on dispose au verso de l'étiquette une couche adhésive recouverte d'une feuille protectrice.The electronic module 13 is then overmolded in a pawn 101, then we have on the back of the label a adhesive layer covered with a protective sheet.

Lesdits flans 2 et 6 sont fixés l'un à l'autre par un adhésif ayant une force d'adhésion inférieure à celle de l'adhésif utilisé au verso de l'étiquette.Said blanks 2 and 6 are fixed to each other by a adhesive with lower adhesion strength than the adhesive used on the back of the label.

Ainsi, lorsque l'étiquette 100 ainsi réalisée est collée sur un objet et que l'on tente de l'en enlever, l'on désolidarise le flan 6 disposé sur le dessus tandis que le flan 2 reste collé sur l'objet et l'on détruit la continuité de l'anneau de détection 15.Thus, when the label 100 thus produced is affixed on an object and we try to remove it, we separates the blank 6 disposed on top while the blank 2 remains stuck on the object and we destroy the continuity of the detection ring 15.

Il est possible de prévoir de marquer sur le flan 6 les données utiles telles que le prix, le code-barre, tandis que l'on réalise sur le flan inférieur 2 des impressions de décoration. L'acheteur de l'article peut alors décoller le flan supérieur 6 et laisser le flan inférieur 2 sur l'article afin de conserver les décorations.It is possible to plan to mark on the blank 6 the useful data such as price, barcode, etc. that we realize on the lower blank 2 impressions of decoration. The buyer of the article can then take off the upper blank 6 and leave lower blank 2 on the article in order to keep the decorations.

Le dispositif de marquage selon l'invention permet bien entendu à un client bien intentionné, ne cherchant pas à décoller l'étiquette, d'observer l'objet, de l'essayer s'il s'agit d'un vêtement, de le reposer, sans que le système de surveillance soit alerté.The marking device according to the invention allows well heard to a well-intentioned client, not seeking to peel off the label, observe the object, try it if it is a piece of clothing, to put it back on, without the surveillance be alerted.

Lors d'un passage licite de l'article portant une étiquette selon l'invention à une caisse du magasin, un signal électrique codé est induit dans le circuit électronique à travers l'anneau de détection fonctionnant alors à la manière d'une antenne afin de désactiver le dispositif de marquage. Ce signal peut être un signal conçu de puissance suffisante pour assurer la destruction par vaporisation d'un fusible. Ce fusible est un fusible intégré de manière connue et usuelle dans le module électronique. Ce signal de destruction peut être émis au moment de la lecture du code barre porté par l'étiquette pour définir l'objet et son prix.During a lawful passage of the article bearing a label according to the invention at a store counter, a signal coded electrical is induced in the electronic circuit to through the detection ring then operating at the way of an antenna in order to deactivate the device marking. This signal can be a designed signal of power sufficient to ensure destruction by vaporization of a fuse. This fuse is a fuse integrated so known and usual in the electronic module. This signal from destruction can be issued when reading the code bar carried by the label to define the object and its price.

Grâce à la mise en oeuvre d'un module électronique, l'on peut prévoir de contrôler la destruction effective du fusible avant de valider l'enregistrement du prix ce qui permet de s'assurer que la désactivation du dispositif de marquage selon l'invention est bien réalisée.Thanks to the implementation of an electronic module, may plan to control the actual destruction of the fuse before confirming the registration of the price which ensures that the deactivation of the marking according to the invention is well carried out.

Ainsi, l'étiquette selon l'invention est rendue inopérante après que l'article a été licitement sorti du magasin ce qui le rend indétectable par d'autres systèmes de surveillance à travers lesquels l'objet pourra être transporté après son paiement.Thus, the label according to the invention is rendered inoperative after the item was lawfully taken out of the store this which makes it undetectable by other systems of surveillance through which the object can be transported after payment.

La réserve d'énergie d'une telle étiquette peut être augmentée par la mise en oeuvre d'un condensateur dans le circuit électronique, un tel condensateur étant de préférence obtenu par impression directe ou superposition de couches conductrices.The energy reserve of such a label can be increased by the use of a capacitor in the electronic circuit, such a capacitor being of preference obtained by direct printing or overlay of conductive layers.

D'autres moyens de fragilisation tels que des lignes de fragilisation peuvent enfin être prévues dans l'étiquette de manière à aider la survenue des coupures en provoquant un déchirement de l'étiquette en plusieurs parties ce qui entraíne de manière sûre et incontournable la rupture de l'anneau de détection 15.Other means of embrittlement such as lines of embrittlement can finally be provided in the label so as to help the occurrence of cuts by causing a tear of the label into several parts which leads in a sure and unavoidable way the rupture of the detection ring 15.

Bien entendu, la description ci-dessus n'est donnée qu'à titre d'exemple, l'étiquette selon l'invention peut être utilisée pour de nombreuses autres applications telles que l'identification de personnes ou d'objets à leur passage devant des balises, la gestion de colis plus ou moins volumineux comme des paquets dans les services postaux, des bagages dans des aéroports, des bacs de déchets dans les centrales de traitement ...Of course, the above description is given only As an example, the label according to the invention can be used for many other applications such as identifying people or objects as they pass in front of tags, more or less package management bulky like packages in postal services, baggage in airports, waste bins in central processing ...

Les étiquettes selon l'invention permettraient alors à la fois l'identification des personnes ou choses, la détection de toute tentative de fraude, telle que le transfert d'une étiquette d'une personne autorisée à une personne non autorisée, l'arrachage d'étiquette afin de détourner des colis, et pourraient être rendues inopérantes lors de la sortie de la personne ou de l'objet porteur de l'étiquette à la sortie de la zone surveillée.The labels according to the invention would then allow the once identifying people or things, detecting any attempted fraud, such as the transfer of a label of a person authorized to a person not authorized, peeling of labels in order to divert parcel, and could be rendered inoperative when exit of the person or object carrying the label at the exit of the monitored area.

Le module électronique peut être pourvu d'une mémoire permettant le stockage de toute donnée utile et d'un microprocesseur pour le traitement de ces données en liaison avec des moyens externes. Les dispositifs de marquage selon l'invention peuvent ainsi être utilisés pour effectuer des tris de colis.The electronic module can be provided with a memory allowing the storage of all useful data and a microprocessor for processing this data in liaison with external means. The devices marking according to the invention can thus be used for carry out parcel sorting.

En variante, pour des besoins spécifiques, il est également envisageable de prévoir des contacts externes sur l'étiquette afin de lui conférer d'autres possibilités de dialogue avec des lecteurs adéquats à la manière des cartes à puces.Alternatively, for specific needs, it is also possible to envisage external contacts on the label in order to give it other possibilities of dialogue with suitable readers like cards flea.

Dans la variante de réalisation représentée à la figure 3, le dispositif de marquage comporte, en plus de l'anneau de détection 15, une antenne émettrice/réceptrice 14 raccordée au module électronique 13.In the variant embodiment shown in FIG. 3, the marking device comprises, in addition to the ring of detection 15, a transmitter / receiver antenna 14 connected to the electronic module 13.

Cette forme de réalisation permet de continuer à assurer l'alimentation électrique du module électronique même après la coupure de l'anneau de détection 15, tant que ladite antenne n'est pas détruite.This embodiment allows to continue to ensure the power supply of the electronic module even after the interruption of the detection ring 15, as long as said antenna is not destroyed.

Il est alors possible de continuer à dialoguer avec ledit module électronique après la détection de la tentative de fraude, par exemple pour identifier l'article et/ou pour effectuer sa recherche dans la zone surveillée.It is then possible to continue to dialogue with said electronic module after detection of the attempted fraud, for example to identify the article and / or to search in the monitored area.

De telles étiquettes seront fabriquées en ajoutant une antenne 14 dans le flan 2 au cours de la mise en oeuvre du procédé décrit aux figures 2a à 2e.Such labels will be made by adding a antenna 14 in the blank 2 during the implementation of the process described in FIGS. 2a to 2e.

Les étiquettes peuvent par exemple être réalisées à partir d'un ruban de matériau support tel que du polystyrène, du chlorure de polyvinyle ou de l'ABS. Ce ruban peut être préalablement obtenu par tout dispositif de fabrication connu tel que laminage, coulage, extrusion, ou injection ... D'autres matériaux peuvent bien entendu être utilisés pour constituer ledit ruban tels qu'un polyamide.Labels can for example be made from a ribbon of support material such as polystyrene, polyvinyl chloride or ABS. This ribbon can be previously obtained by any manufacturing device known as rolling, casting, extrusion, or injection ... Other materials can of course be used to form said tape such as a polyamide.

On forme un ruban portant des étiquettes terminées et on l'enroule avec interposition éventuelle d'un intercalaire permettant d'absorber la différence d'épaisseur entre le pion et le reste de l'étiquette.We form a ribbon with finished labels and we rolls it up with possible interposition of a spacer to absorb the difference in thickness between the pawn and the rest of the label.

Ce ruban pourra alors être utilisé dans les machines à coller de type connu.This tape can then be used in machines paste of known type.

L'utilisation d'un ruban de matière est bien entendu décrite à titre d'exemple, les étiquettes pouvant être obtenues à partir d'un support de toute autre forme telle qu'une plaque dans laquelle seraient découpées les étiquettes en une succession de colonnes.The use of a material ribbon is of course described by way of example, the labels being able to be obtained from a support of any other form such that a plate from which the labels in a succession of columns.

En variante, l'on dispose l'anneau de détection 15 en forme de huit de manière à le rendre insensible aux émissions parasites pouvant être présentes dans les locaux renfermant les objets à surveiller. Il est également possible de disposer plusieurs telles boucles en forme de huit.As a variant, the shaped detection ring 15 is placed of eight so as to make it immune to emissions parasites which may be present in the premises containing objects to watch. It is also possible to arrange several such eight-shaped loops.

La rupture de l'anneau de détection est immédiatement détectée par le module électronique et celui-ci envoie, par son antenne 14 utilisée en émission, un signal qu'interprète le réseau de surveillance interne du magasin. The rupture of the detection ring is immediately detected by the electronic module and this sends, by its antenna 14 used in transmission, a signal interpreted by the store's internal surveillance network.

Le signal émis par le module électronique d'un dispositif de marquage selon l'invention peut être un simple signal d'alarme, mais peut également être porteur d'informations donnant la nature exacte de l'objet en cause.The signal emitted by the electronic module of a device marking according to the invention can be a simple signal alarm, but can also carry information giving the exact nature of the object in question.

Dans la zone de sortie, des moyens de surveillance semblables à ceux couramment utilisés à l'heure actuelle assurent la détection de tout objet porteur d'une étiquette que celle-ci soit entière ou qu'il n'en reste plus que la partie portant le module électronique.In the exit area, surveillance means similar to those commonly used today detect any object bearing a label whether it is whole or only the part carrying the electronic module.

L'utilisation d'un module électronique avec lequel l'on peut faire dialoguer des moyens de détection permet d'éviter des détections intempestives dans les zones de sortie.The use of an electronic module with which can cause detection means to dialogue avoid untimely detections in areas of exit.

Le pion enfermant le module électronique peut être moulé dans une matière transparente afin de permettre des transmissions d'informations par signaux lumineux.The pin enclosing the electronic module can be molded in a transparent material to allow transmission of information by light signals.

De manière connue en soi dans le domaine de la fabrication par moulage d'articles en matière plastique, lesdits dispositifs de marquage peuvent être décorés au moment de leur moulage sur toute leur surface ou seulement en partie ou peuvent être décorés par la suite, à la demande, en fonction de la destination des dispositifs de marquage.In a manner known per se in the field of manufacturing by molding plastic articles, said articles marking devices can be decorated at the time of their molding over their entire surface or only in part or can be decorated later, on request, in depending on the destination of the marking devices.

La figure 4 représente une variante de réalisation d'un dispositif de marquage selon l'invention dans laquelle deux antennes réceptrices/émettrices sont prévues afin d'augmenter les chances de conserver une antenne capable de transmettre les informations après une tentative d'arrachage de l'étiquette.FIG. 4 represents an alternative embodiment of a marking device according to the invention in which two receiving / transmitting antennas are provided to increase the chances of keeping an antenna capable of transmit information after an attempt peel off the label.

Il est bien entendu possible d'augmenter le nombre desdites antennes si les dimensions de l'étiquette le permettent.It is of course possible to increase the number of said antennas if the dimensions of the label allow it.

En laminant les antennes 14 dans le corps de l'étiquette afin d'assurer que celles-ci ne soient pas rompues lors de l'arrachage, l'on améliore encore la fiabilité de l'étiquette en ce qui concerne la détection d'un arrachage.By laminating the antennas 14 in the body of the label to ensure that these are not broken during uprooting, the reliability of the label with regard to the detection of a grubbing up.

La détection peut constater la rupture de la continuité de l'anneau comme décrit ci-dessus, mais peut également constater une modification des caractéristiques électriques du circuit de détection.The detection can note the break in the continuity of the ring as described above, but can also note a change in the electrical characteristics of the detection circuit.

Le module électronique est à cet effet prévu de manière à pouvoir détecter une variation de la résistance du circuit.To this end, the electronic module is designed to ability to detect a change in circuit resistance.

L'on peut également prévoir d'examiner la conductance ou l'inductance de l'anneau de détection.One can also plan to examine the conductance or the inductance of the detection ring.

Les figures 5 et 6 montrent deux exemples de réalisation du circuit électronique pour des dispositifs de marquage selon l'invention.Figures 5 and 6 show two embodiments of the electronic circuit for marking devices according to the invention.

Sur ces dessins, le composant électronique mis en oeuvre est représenté par le cadre 53 ou 63.In these drawings, the electronic component used is represented by box 53 or 63.

Il reçoit des informations sur l'état du dispositif de marquage par l'anneau de détection 55 et est en relation avec un système de surveillance par l'antenne 54.It receives information about the status of the marking by the detection ring 55 and is related with an antenna surveillance system 54.

Dans les exemples non limitatifs de réalisation de ces figures 5 et 6, l'antenne est unique et assure la réception et l'émission de messages sur une même fréquence porteuse.In the nonlimiting examples of embodiment of these Figures 5 and 6, the antenna is unique and ensures reception and the transmission of messages on the same carrier frequency.

Dans les exemples représentés, une bobine 50 assure la fourniture en énergie du module électronique, elle peut être constituée par l'anneau de détection ou toute autre bobine comprise dans le dispositif, par exemple les antennes 14 de figures 3 et 4.In the examples shown, a coil 50 ensures the energy supply of the electronic module, it can be constituted by the detection ring or any other coil included in the device, for example antennas 14 of Figures 3 and 4.

Cette énergie est redressée et stabilisée dans le récepteur-redresseur 70.This energy is rectified and stabilized in the receiver-rectifier 70.

Un fusible 71 est disposé entre la bobine 50 et le récepteur-redresseur 70. A fuse 71 is disposed between the coil 50 and the receiver-rectifier 70.

Un circuit 72 assure la réception et la démodulation des informations captées par l'antenne 54 et envoie ces informations vers un dispositif de traitement des données 74.A circuit 72 ensures reception and demodulation of information received by antenna 54 and sends these information to a data processing device 74.

Ledit dispositif de traitement des données 74 reçoit également un signal d'horloge en provenance du circuit 75.Said data processing device 74 receives also a clock signal from circuit 75.

A partir des informations reçues soit du circuit 72 de réception et démodulation, soit de l'anneau de détection 55, ce dispositif de traitement des données 74 délivre au circuit 73 un signal qui est modulé et émis par l'antenne 54.From the information received either from circuit 72 of reception and demodulation, either of the detection ring 55, this data processing device 74 delivers to the circuit 73 a signal which is modulated and transmitted by the antenna 54.

Lorsqu'un tel dispositif passe entre les antennes émettrice/réceptrice du système de surveillance disposées à la sortie de la zone surveillée, il reçoit dudit système de surveillance un signal d'appel, par exemple sous forme d'une modulation de la fréquence porteuse.When such a device passes between the antennas surveillance system transmitter willing to leaving the monitored area, it receives from said system monitoring a call signal, for example in the form carrier frequency modulation.

Le dispositif de traitement des données 74 identifie ce signal d'appel et déclenche l'émission d'un signal de réponse par le circuit 73.The data processing device 74 identifies this call signal and triggers the emission of a signal response through circuit 73.

Ces signaux d'appel et de réponse peuvent bien entendus être codés, par exemple par l'utilisation de fréquences de modulation différentes.These call and response signals can be heard be coded, for example by the use of frequencies of different modulation.

Lorsque l'on tente d'arracher le dispositif de marquage de l'objet qui le porte, le dispositif de traitement des données 74 reçoit l'information de l'anneau de détection 55 et déclenche l'émission d'un signal.When trying to tear off the marking device the object that carries it, the device for processing data 74 receives information from detection ring 55 and triggers the emission of a signal.

Dans un troisième cas, celui au cours duquel l'article est amené en caisse par un acheteur, un apport d'énergie important est réalisé, conduisant à la destruction du fusible 71. In a third case, the one in which the article is brought in cash by a buyer, an energy contribution important is achieved, leading to the destruction of the fuse 71.

L'exemple de réalisation représenté à la figure 6 diffère de celui représenté à la figure 5 en ce qu'il comporte un module de sécurité 76 formé par un calculateur et une mémoire 77 accessible uniquement par ce module de sécurité.The embodiment shown in Figure 6 differs of that shown in Figure 5 in that it comprises a security module 76 formed by a computer and a memory 77 accessible only by this security module.

Cette forme de réalisation permet d'établir un dialogue entre le système de surveillance et l'étiquette. La mémoire peut contenir des données spécifiques au produit, au magasin, etc ...This embodiment makes it possible to establish a dialogue between the monitoring system and the label. Memory may contain data specific to the product, store, etc ...
