Description

ETIQUETTE DESTINEE A ETRE ASSOCIEE A UN PRODUIT OU ARTICLE POUR PERMETTRE D'EN CONTROLER LA PRESENCE LABEL TO BE ASSOCIATED WITH A PRODUCT OR ARTICLE TO ENABLE TO CONTROL THE PRESENCE
L'invention se rapporte à une étiquette destinée à être associée à un produit ou article pour, en combinaison svec au moins un moyen extérieur, permettre d'en ccr.trδier ia présence et donc incidemment celle du produit ou article en un lieu choisi tel la sortie d'un point de vente.The invention relates to a label intended to be associated with a product or article in order, in combination with at least one external means, to make it possible to create a presence and therefore incidentally that of the product or article in a chosen place such leaving a point of sale.
Elle se rapporte également à chacun des moyens pouvant être combinés avec au moins une telle étiquette dans une installation de surveillance de la présence d'au moins un produit et notamment des moyens en vue :It also relates to each of the means that can be combined with at least one such label in an installation for monitoring the presence of at least one product and in particular means for:
- de son activation et de sa désactivation,- its activation and deactivation,
- de sa détection en un lieu où cela est anormal.- its detection in a place where this is abnormal.
- de la signalisation, visuelle et/ou sonore, de ces anomalies.- visual and / or audible signaling of these anomalies.
On connaît déjà, ainsi combinées à des moyens extérieurs remplissant de sembabies fonctions de telles étiquettes (GB-A-1129761 ) accrochables sur des vêtements, desquels ensuite elles ne peuvent en principe être ôtées, sans détérioration, que par un outil spécial.It is already known, thus combined with external means filling sembabies with the functions of such labels (GB-A-1129761) which can be hung on clothes, from which they can in principle only be removed, without deterioration, by a special tool.
Ces étiquettes connues comprennent :These known labels include:
- un circuit en plusieurs tronçons qui assure la liaison entre les éléments de l'étiquette, incluant éventuellement une source de courant électrique qui donc est intégrée à l'étiquette,- a circuit in several sections which ensures the connection between the elements of the label, possibly including a source of electric current which therefore is integrated into the label,
- un moyen d'émission d'un signal à destination d'un récepteur porté par un moyen extérieur donnant l'alarme,a means of transmitting a signal to a receiver carried by an external means giving the alarm,
- un récepteur qui, lorsqu'il est à portée d'un émetteur porté par un moyen extérieur et qu'il capte le signal de ce t émetteur agit sur un dispositif, porté par l'étiquette, coinma.ndant l'action du moyen d'émission.- a receiver which, when it is within range of a transmitter carried by an external means and that it receives the signal from this t transmitter acts on a device, carried by the label, coinma.ndant the action of the means resignation.
Dans ces dispositifs connus, le récepteur consiste en un circuit résonnant sous une première fréquence tandis que le moyen d'émission consiste en un second circuit résonnant sous une autre fréquence et qui, après correction de la fréquence du signal capté par le récepteur, assure simplement et systématiquement la réémission du signal ainsi capté.In these known devices, the receiver consists of a circuit resonating at a first frequency while the transmission means consists of a second circuit resonating at another frequency and which, after correction of the frequency of the signal picked up by the receiver, simply ensures and systematically the retransmission of the signal thus received.
Il s'agit donc d'un circuit passif en ce sens qu'il peut opérer avec ia seule énergie du signal capté et que l'adjonction éventuelle d'une source de courant électrique n'a pour but que d'amplifier le signal réémis et non par exemple d'alimenter un émetteur autonome, générant un signal indépendant de celui reçu.It is therefore a passive circuit in the sense that it can operate with only the energy of the signal picked up and that the possible addition of a source of electric current is only intended to amplify the re-transmitted signal and not for example to supply a stand-alone transmitter, generating a signal independent of that received.
Quant au moyen en vue de son activât ion et de sa désactivation, il consiste en un élément non conducteur mais magnétisable, tel une ferrite, logé près du circuit résonnant de réception et qui :As for the means for its activation and deactivation, it consists of a non-conductive but magnetizable element, such as a ferrite, housed near the resonant reception circuit and which:
- lorsqu'il n'est pas magnétisé, n'a pas d'effet mais qui, - lorsqu'il est magnétisé, crée avec le champs électromagnétique du signal capté par le récepteur, une interférence qui interdit le fonctionnement du réémetteur.- when it is not magnetized, has no effect but which, - when it is magnetized, creates with the electromagnetic field of the signal picked up by the receiver, interference which prohibits the operation of the re-emitter.
Toutefois, indépendamment de cette ferrite, ces étiquettes peuvent également subir des interférences d'autres circuits ou être inhibées par des corps qui, entre l'étiquette et au moins l'un des moyens extérieurs d'émission et de réception, forment des masques.However, independently of this ferrite, these labels can also be subject to interference from other circuits or be inhibited by bodies which, between the label and at least one of the external transmission and reception means, form masks.
De ce fait elles se sont révélées d'une efficacité aléatoire. E-lles ont également pour inconvénient de pouvoir, par quiconque et sans précaution spéciale, être ôtées, certes en détériorant l'étiquette, mais sans -pour cela déclencher l'alarme.As a result, they have proved to be of random effectiveness. They also have the disadvantage of being able, by anyone and without any special precaution, to be removed, certainly by damaging the label, but without doing this to raise the alarm.
Par ailleurs, lorsque l'alarme est déclenchée, elle s'arrête généralement aussitôt que l'étiquette quitte la zone du passage entre les points d'émission et de réception des signaux susceptibles d'être captés puis mis en forme et réémis par l'étiquette qui en elle-même reste passive et ne peut donc à elle seule générer le signal de commande de l'alarme.Furthermore, when the alarm is triggered, it generally stops as soon as the label leaves the zone of passage between the points of emission and reception of the signals likely to be picked up then formatted and re-emitted by the label which in itself remains passive and therefore cannot on its own generate the alarm control signal.
Un résultat que l'invention vise à obtenir est une étiquette du type cité plus haut, dont l'efficacité est certaine et qui, de plus, ne peut être dissociée de l'article qu'elle protège sans déclencher un signal visuel et/ou sonore.One result which the invention aims to obtain is a label of the type mentioned above, whose effectiveness is certain and which, moreover, cannot be dissociated from the article which it protects without triggering a visual signal and / or sound.
Un autre résultat que l'invention vise à obtenir est une étiquette susceptible d'être adaptée de manière à ne répondre qu'à un code précis, modifiable. Est également un résultat que l'invention vise à obtenir une telle étiquette dont la présence peut être aisément détectée sans nécessiter son encadrement par des moyens extérieurs d'émission et de réception et donc efficace même au delà du moyen extérieur d'émission et, donc par exemple, encore après la sortie d'un point de vente, à l'aide d'un seul poste émetteur-récepteur extérieur portatif.Another result which the invention aims to obtain is a label capable of being adapted so as to respond only to a precise, modifiable code. Is also a result that the invention aims to obtain such a label whose presence can be easily detected without requiring its supervision by external means of emission and reception and therefore effective even beyond the external means of emission and, therefore for example, even after leaving a point of sale, using a single portable outdoor transceiver station.
A cet effet, l'invention a pour objet une étiquette du type cité plus haut, notamment caractérisée en ce que le moyen d'émission porté par l'étiquette est un émetteur autonome qui, pour émettre, doit essentiellement être raccordé à la source de courant électrique et en ce que, à cet effet, l'étiquette comprend un circuit, dit principal scindé en plusieurs tronçons successifs par au moins un commutateur principal relié à au moins un moyen de commande.To this end, the subject of the invention is a label of the type mentioned above, in particular characterized in that the emission means carried by the label is an autonomous transmitter which, in order to transmit, must essentially be connected to the source of electric current and in that, for this purpose, the label comprises a circuit, called main divided into several successive sections by at least one main switch connected to at least one control means.
Elle a également pour objet chacun des moyens extérieurs pouvant être combinés avec au moins une telle étiquette dans une installation de surveillance de la présence d'au moins un produit ou article ainsi que l'installation correspondante.It also relates to each of the external means which can be combined with at least one such label in an installation for monitoring the presence of at least one product or article as well as the corresponding installation.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schémati quement :The invention will be better understood with the aid of the description below given by way of nonlimiting example, with reference to the attached drawing which schematically represents:

Dans ce dessin, le circuit principal a été représenté en trait plus fort que les éléments des circuits auxiliaires de commande. En se reportant à ce dessin, on voit que l'installation de surveillance comprend au moins une étiquette 1 comprenant :In this drawing, the main circuit has been shown in a stronger line than the elements of the auxiliary control circuits. Referring to this drawing, it can be seen that the monitoring installation comprises at least one label 1 comprising:
- un circuit en plusieurs tronçons 17 à 20 qui assure la liaison entre les éléments de l'étiquette et inclue une source de courant électrique 21 qui donc est intégrée à l'étiquette.- a circuit in several sections 17 to 20 which ensures the link between the elements of the label and includes an electric current source 21 which is therefore integrated into the label.
- un moyen d'émission 7 d'un signal 6 à destination d'un récepteur 5 d'un moyen extérieur 4 donnant l'alarme,a means 7 for transmitting a signal 6 to a receiver 5 of an external means 4 giving the alarm,
- un récepteur 11 qui, lorsqu'il est à portée d'un émetteur 9 d'un moyen extérieur 3 et qu'il capte le signal 10 de cet émetteur 9 agit sur un dispositif 30 commandant l'action du moyen d'émission. Elle est donc combinée avec au moins un moyen extérieur- A receiver 11 which, when it is within range of a transmitter 9 of an external means 3 and that it picks up the signal 10 from this transmitter 9 acts on a device 30 controlling the action of the transmission means. It is therefore combined with at least one external means
2, 3, 4 dont notamment : d'une part, au moins un moyen 4 comprenant un récepteur 5 d'un signal 6 reçu d'un moyen d'émission 7 porté par l'étiquette, lequel récepteur 5 commande au moins une alarme 8 et,2, 3, 4 including in particular: on the one hand, at least one means 4 comprising a receiver 5 of a signal 6 received from a transmission means 7 carried by the label, which receiver 5 controls at least one alarm 8 and,
- d'autre part, au moins un moyen 3 qui comprend un émetteur 9 d'un signal 10 qui, lorsqu'il est capté par un récepteur 11 porté par l'étiquette 1, fait agir le dispositif de commande 30 porté par la dite étiquette pour lui faire émettre le signal 6 attendu par le moyen extérieur cité ci-dessus pour assurer à son tour la commande de l'alarme 8.- on the other hand, at least one means 3 which comprises a transmitter 9 of a signal 10 which, when picked up by a receiver 11 carried by the label 1, activates the control device 30 carried by said label to make it emit the signal 6 expected by the external means mentioned above to in turn ensure control of the alarm 8.
L'étiquette peut comprendre également un organe 13, sensible à un signal extérieur 14, qui est apte à mettre la dite étiquette alternativement en repos ou en état de fonctionner.The label can also include a member 13, sensitive to an external signal 14, which is capable of placing said label alternately in rest or in working order.
Cette étiquette est alors également combinée avec au moins un moyen extérieur 12 supplémentaire communiquant avec cet organe sensible 13 porté par l'étiquette.This label is then also combined with at least one additional external means 12 communicating with this sensitive member 13 carried by the label.
Selon une caractéristique essentielle de l'invention, le moyen d'émission 7 porté par l'étiquette est un émetteur autonome qui, pour émettre, doit essentiellement être raccordé à la source 21 de courant électrique et, à cet effet, l'étiquette porte un circuit dit principal scindé en plusieurs tronçons successifs 17 à 20 par au moins un commutateur principal 30 relié à au moins un moyen de commande.According to an essential characteristic of the invention, the transmission means 7 carried by the label is a stand-alone transmitter which, in order to transmit, must essentially be connected to the source 21 of electric current and, for this purpose, the label carries a so-called main circuit divided into several successive sections 17 to 20 by at least one main switch 30 connected to at least one control means.
Selon une autre caractéristique de l'invention, l'éventuel organe sensible 13 qui, à réception d'un signal extérieur 14 est apte à mettre l'étiquette alternativement en repos ou en état de fonctionner, pilote un commutateur 16 scindant en plusieurs tronçons successifs 17, 18, 19, 20 le circuit principal d'alimentation de l'émetteur 7 du signal 6 commandant le moyen d'alarme 4.According to another characteristic of the invention, the possible sensitive member 13 which, upon reception of a signal outside 14 is able to put the label alternately in rest or in working order, controls a switch 16 dividing into several successive sections 17, 18, 19, 20 the main supply circuit of the transmitter 7 of the signal 6 controlling the alarm means 4.
La communication entre le moyen extérieur 12 et cet organe sensible 13 peut s'opérer par tout moyen connu tel que par ultrasons, ondes radio et/ou de préférence par un signal codé de manière à être porteur d'une information sur le prix et/ou la référence du produit particulier appelé à recevoir l'étiquette.The communication between the external means 12 and this sensitive member 13 can take place by any known means such as by ultrasound, radio waves and / or preferably by a coded signal so as to carry information on the price and / or the reference of the particular product called to receive the label.
Ce moyen qui pourra être logé dans un boîtier pourra en outre être lui-même commandé manuellement ou automatiquement par tout moyen connu et ce, par exemple, par l'intermédiaire de la caisse enregistrant le paiement du produit protégé par l'étiquette et/ou par l'ordinateur contrôlant la concordance entre code de l'étiquette lu par la caisse enregistreuse et le prix du produit tel que rentré dans les données de l'ordinateur comme correspondant à la référence du dit produit, pour n'autoriser la mise en repos de l'étiquette qu'après paiement de l'article à son juste prix.This means which can be housed in a box can also be itself controlled manually or automatically by any known means and this, for example, through the cash register registering the payment for the product protected by the label and / or by the computer checking the concordance between the code of the label read by the cash register and the price of the product as entered in the computer data as corresponding to the reference of the said product, in order to authorize the rest of the label only after payment of the article at its fair price.
Le commutateur 16 piloté par cet organe sensible peut par exemple faire partie d'un ensemble 15 comprenant en outre un organe 22 déterminant l'état de ce commutateur 16. Dans l'exemple de réalisation, objet de la figure 2, ce commutateur 16 consistera en au moins un transistor 23 aux collecteur 24 et émetteur 25 duquel sont raccordées les extrémités en vis à vis des deux tronçons correspondants 17, 18 du circuit d'alimentation de l'émetteur 7. Par définition, un transistor est passant de son collecteur à son émetteur et correspond donc à un commutateur fermé lorsque sa base 26 est alimentée par une tension de commande équivalente à celle reçue au collecteur 24 alors qu'il se bloque et correspond donc à un commutateur ouvert lorsque sa base 26 reçoit une tension de commande de l'ordre du zéro.The switch 16 controlled by this sensitive member can for example be part of an assembly 15 further comprising a member 22 determining the state of this switch 16. In the embodiment, object of FIG. 2, this switch 16 will consist in at least one transistor 23 at the collector 24 and emitter 25 of which are connected the opposite ends of the two corresponding sections 17, 18 of the supply circuit of the emitter 7. By definition, a transistor is passed from its collector to its transmitter and therefore corresponds to a closed switch when its base 26 is supplied with a control voltage equivalent to that received at the collector 24 while it is blocked and therefore corresponds to an open switch when its base 26 receives a control voltage from the order of zero.
Le transistor 23 de ce commutateur 16 peut bien entendu être combiné à au moins un autre transistor 23' fonctionnant de même manière du fait que son collecteur 24' est raccordé au collecteur 24 du précédent alors que son émetteur 25' est raccordé à la base 26 du précédent pour lui fournir sa tension de commande lorsque celui-ci reçoit une telle tension à sa base 26'.The transistor 23 of this switch 16 can of course be combined with at least one other transistor 23 'operating in the same way of the fact that its collector 24 'is connected to the collector 24 of the previous one while its transmitter 25' is connected to the base 26 of the previous one to supply it with its control voltage when the latter receives such a voltage at its base 26 '.
Qu'il comprenne un ou plusieurs transistors, un tel commutateur 16 demande alors à être raccordé à l'organe 22 déterminant son état par une ligne 27 recevant alternativement du dit organe 22 soit une tension de l'ordre du zéro soit une tension de l'ordre de celle de la source d'alimentation 21.Whether it includes one or more transistors, such a switch 16 then needs to be connected to the member 22 determining its state by a line 27 alternately receiving from the said member 22 either a voltage of the order of zero or a voltage of l of the power source 21.
Pour cela l'organe 22 consiste par exemple en une bascule à commande par transition réglée de manière à fournir en sortie 29 alternativement l'une ou l'autre des tensions évoquées plus haut en réponse à chaque signal reçu et qui, après un éventuel décodage, est validé par le récepteur 13 auquel il est associé par une ligne d'entrée 28.For this, the member 22 consists for example of a flip-flop with transition control adjusted so as to provide at output 29 alternately one or the other of the voltages mentioned above in response to each signal received and which, after a possible decoding , is validated by the receiver 13 with which it is associated by an input line 28.
Bien entendu, en l'absence de décodeur, pour garder un contrôle facile de l'état final de l'étiquette, il est préférable de n'adresser au récepteur 13 qu'une seule impulsion par commande.Of course, in the absence of a decoder, to keep easy control of the final state of the label, it is preferable to send the receiver 13 only one pulse per command.
Qu'elle soit imposée par la construction ou qu'elle résulte de la commande par l'éventuel organe sensible 13, il ne faut évidemment pas que la seule mise en état de fonctionner de l'étiquette détermine systématiquement et sans autre raison l'alimentation de l'émetteur 7, porté par l'étiquette, qui commande le moyen extérieur d'alarme 4.Whether it is imposed by the construction or whether it results from the command by the possible sensitive member 13, it is obviously not necessary that the mere setting in working order of the label systematically and without other reason determines the feeding. of the transmitter 7, carried by the label, which controls the external alarm means 4.
C'est pourquoi, comme indiqué plus haut, entre deux tronçons 19, 20 du circuit d'alimentation de cet émetteur 7 est intercalé le commutateur 30 relié à au moins un moyen de commande 11, 34.This is why, as indicated above, between two sections 19, 20 of the supply circuit of this transmitter 7 is interposed the switch 30 connected to at least one control means 11, 34.
Dans le cas où l'étiquette comprend un organe sensible 13 et son commutateur 16 plaçant l'étiquette en état de repos ou de fonctionner, le commutateur 30 et le commutateur 16 peuvent être confondus, comme c'est par exemple le cas dans la variante de réalisation représentée à la figure 4 et qui sera décrite plus loin.In the case where the label comprises a sensitive member 13 and its switch 16 placing the label in a state of rest or of functioning, the switch 30 and the switch 16 can be merged, as is for example the case in the variant of embodiment shown in Figure 4 and which will be described later.
Il peut également s'agir de commutateurs séparés. Dans ce cas, le commutateur 30 consistera par exemple en un thyristor qui, par définition, pour devenir passant et correspondre donc à un commutateur fermé, doit recevoir à sa gâchette 31 un courant suffisant. Un intérêt essentiel que présente un thyristor pour constituer ce commutateur 30 est qu'après avoir été amorcé par la réception de ce courant suffisant, ce thyristor reste passant même si le courant de commande disparaît, sauf bien entendu en cas de coupure du circuit principal 19, 20 par exemple, par action d'un autre commutateur 16.They can also be separate switches. In this case, the switch 30 will consist for example of a thyristor which, by definition, to become on and therefore correspond to a closed switch, must receive at its trigger 31 a sufficient current. An essential advantage of a thyristor for constituting this switch 30 is that after having been initiated by the reception of this sufficient current, this thyristor remains on even if the control current disappears, except of course in the event of a break in the main circuit 19 , 20 for example, by the action of another switch 16.
Grâce à cette particularité dès que le thyristor sera passant et que, via l'émetteur 7 et le moyen extérieur 4, l'alarme sera actionnée, celle-ci persistera même si les causes de l'amorçage disparaissent. Pour cet amorçage, la gâchette du thyristor est relié à au moins un moyen de commande par une ligne 32.Thanks to this feature as soon as the thyristor is on and when, via the transmitter 7 and the external means 4, the alarm is activated, it will persist even if the causes of the ignition disappear. For this priming, the trigger of the thyristor is connected to at least one control means by a line 32.
L'un de ces moyens est par exemple intégré au récepteur 11 porté par l'étiquette.One of these means is for example integrated into the receiver 11 carried by the label.
Il est de tout type apte à envoyer à la gâchette 31 le courant d'amorçage lorsqu'il est à portée d'un signal convenable 10 fournit par au moins un moyen extérieur 3 tel un émetteur portatif ou une borne fixe situé de manière à émettre dans une zone où l'on veut déceler la présence d'étiquette en état de fonctionner. Outre le contrôle de l'alarme, le rôle d'interrupteur du thyristor a également pour avantage de limiter la consommation du circuit de l'étiquette à celle juste nécessaire à ses propres moyens récepteurs 11, 13 et émetteur 7 de liaison avec les moyens extérieurs 2, 3, 4. Pour son association à l'article 35 à protéger, l'étiquette comprend des moyens 46 à 48, tels une agrafe 36.It is of any type suitable for sending the trigger 31 the priming current when it is within range of a suitable signal 10 supplied by at least one external means 3 such as a portable transmitter or a fixed terminal situated so as to transmit in an area where you want to detect the presence of a working label. In addition to controlling the alarm, the role of thyristor switch also has the advantage of limiting the consumption of the tag circuit to that just necessary for its own receiver means 11, 13 and transmitter 7 for connection with external means 2, 3, 4. For its association with article 35 to be protected, the label includes means 46 to 48, such as a clip 36.
Selon une caractéristique de l'invention, on pourra utiliser comme agrafe 36 une plaquette 46 pourvue d'un doigt 47 traversant le produit 35 s'engageant et se verrouillant dans un orifice 48 de l'étiquette.According to a characteristic of the invention, it is possible to use as a clip 36 a plate 46 provided with a finger 47 passing through the product 35 engaging and locking in an orifice 48 of the label.
Ces moyens d'association à l'article sont combinés à un organe 34 pilotant le commutateur 30 intercalé entre les tronçons successifs du circuit principal d'alimentation de l'émetteur 7 de manière à fermer le circuit et donc à permettre l'émission en cas de dissociation de l'étiquette de son article 35.These means of association with the article are combined with a member 34 controlling the switch 30 interposed between the successive sections of the main supply circuit of the transmitter 7 so as to close the circuit and therefore to allow transmission in the event of dissociation of the label from its article 35.
Par exemple, cet organe 34, contrôlant l'association de l'étiquette 1 et du produit 35, comprend principalement un contact placé entre les bornes 42, 43 d'un circuit de commande 44 et des moyens de commande 49, 50 qui, selon que l'étiquette reste associée au produit ou en est séparée, font que ce contact est fermé ou ouvert. Par exemple, outre ce contact, cet organe comprendra un transistor 37 monté de manière à ce que, d'une part, son collecteur 38 soit directement ou par une faible résistanceFor example, this member 34, controlling the association of the label 1 and of the product 35, mainly comprises a contact placed between the terminals 42, 43 of a control circuit 44 and control means 49, 50 which, according to that the label remains associated with the product or is separated from it, means that this contact is closed or open. For example, in addition to this contact, this member will include a transistor 37 mounted so that, on the one hand, its collector 38 is directly or by a low resistance
39, relié au tronçon 18 du circuit principal et que, d'autre part, son émetteur 40 soit relié à la ligne 32 d'amorçage de la gâchette 31 du thyristor 30.39, connected to the section 18 of the main circuit and that, on the other hand, its transmitter 40 is connected to the line 32 for initiating the trigger 31 of the thyristor 30.
Comme le transistor 23 du premier commutateur 16, le présent transistor 37 est passant et ferme donc le circuit permettant l'amorçage lorsque sa base 41 reçoit un courant suffisant alors que dans le cas contraire il laissera ce circuit ouvert et ne permettra pas l'amorçage.Like the transistor 23 of the first switch 16, the present transistor 37 is conducting and therefore closes the circuit allowing the priming when its base 41 receives a sufficient current whereas in the contrary case it will leave this circuit open and will not allow the priming .
Le contact 42, 43 intervient afin de donner à la base 41, soit le courant suffisant dès qu'on la retire du produit, soit un courant insuffisant dans le cas contraire.The contact 42, 43 intervenes in order to give the base 41 either the sufficient current as soon as it is removed from the product, or an insufficient current in the opposite case.
La ligne 44 sur laquelle est intercalé le contact est reliée entre la base 41 et l'émetteur 40 du transistor 37 dont la dite base 41 est par ailleurs reliée au tronçon 18 du circuit principal par une résistance 45 choisie suffisamment forte pour que le courant qui la traverse ne permette pas d'amorcer le thyristor 30 mais suffisamment faible pour rendre passant le transistor 37.The line 44 on which the contact is inserted is connected between the base 41 and the emitter 40 of the transistor 37, the said base 41 of which is also connected to the section 18 of the main circuit by a resistor 45 chosen to be strong enough for the current which the cross-member does not allow the thyristor 30 to be started but is weak enough to make transistor 37 pass.
Tant que l'agrafe 36 sera bien positionnée, il y aura alors court-circuit entre la base 41 et l'émetteur 40 du transistor 7 et celui-ci restera donc bloqué, par contre, si on enlève l'agrafe , on ouvre ce court circuit et on débloque le transistor 37.As long as the clip 36 is correctly positioned, there will then be a short circuit between the base 41 and the emitter 40 of the transistor 7 and the latter will therefore remain blocked, on the other hand, if we remove the clip, we open this short circuit and the transistor 37 is turned on.
Le transistor présente de surcroît l'avantage de jouer le rôle d'amplificateur ; aussi, le courant émetteur essentiellement dû au courant collecteur est alors suffisant pour exciter la gâchette 31 du thyristor 30 et via l'émetteur 7 commander l'alarme, ce qui implique évidemment que la résistance 39 éventuellement prévue côté collecteur soit suffisamment faible par rapport à celle 45 obligatoirement prévue du côté base.The transistor also has the advantage of playing the role of amplifier; also, the emitter current essentially due to the collector current is then sufficient to excite the trigger 31 of the thyristor 30 and via the transmitter 7 control the alarm, which obviously implies that the resistance 39 possibly provided on the collector side is sufficiently low compared to that 45 necessarily provided on the base side.
Dans une variante de réalisation (figure 4), parmi les éléments de commande de l'étiquette que sont :In an alternative embodiment (FIG. 4), among the control elements of the label that are:
- l'organe 34 de contrôle de l'association de l'étiquette et du produit, - le moyen extérieur 3 contrôlant les passages protégés,the member 34 for controlling the association of the label and the product, the external means 3 controlling the protected passages,
- le moyen extérieur 12 plaçant l'étiquette en état de repos ou de fonctionner par exemple lors du passage régulier en caisse, au moins deux d'entre eux interviennent sur un même commutateur 30 intercalé entre deux des tronçons 17 à 20 du circuit principal par l'intermédiaire de la susdite ligne 32 et de circuits 60, 67, l'un (60) de décodage de l'ordre reçu de ces moyens extérieurs et l'autre (67) de validation de la commande de l'alarme.- The external means 12 placing the label in a state of rest or operating for example during the regular checkout, at least two of them operate on the same switch 30 interposed between two of the sections 17 to 20 of the main circuit by via the above-mentioned line 32 and circuits 60, 67, one (60) for decoding the order received from these external means and the other (67) for validating the alarm command.
Les signaux 10 et 14 envoyés à leur récepteur respectifs 11, 13 ou commun attaquent un décodeur 60 par exemple constitué de circuits intégrés CMOS dont : un compteur 60a. qui analyse le code dont est porteur le signal reçu pour le comparer à un code préalablement rentré à son étage 61 de préréglage et des bascules 60b , 60c propres à chaque type de moyens extérieurs.The signals 10 and 14 sent to their respective receiver 11, 13 or common drive a decoder 60 for example consisting of CMOS integrated circuits including: a counter 60 a . which analyzes the code which carries the received signal to compare it with a code previously returned to its preset stage 61 and flip-flops 60 b , 60 c specific to each type of external means.
L'organe 34 de contrôle de l'association de l'étiquette 1 et de l'article 35 ainsi que les lignes 62 à 65 , 72, 73, 77 et 75/62 raccordées aux sorties du décodeur attaquent le circuit 67 de validation de l'alarme en sortie duquel est raccordée la ligne 32 pilotant le commutateur principal 30 mais aussi un circuit 66 de remise à zéro.The organ 34 for controlling the association of the label 1 and of the article 35 as well as the lines 62 to 65, 72, 73, 77 and 75/62 connected to the outputs of the decoder attack the circuit 67 for validation of the alarm at the output of which is connected the line 32 controlling the main switch 30 but also a reset circuit 66.
Le circuit de validation 67 est constitué de deux portes logiques "OU" 52, 53 et d'une porte logique "NAND" 54. Les entrées 68, 69 de la porte "NAND" 54 sont reliées aux sorties des portes "OU" 52, 53.The validation circuit 67 consists of two "OR" logic gates 52, 53 and a "NAND" logic gate 54. The inputs 68, 69 of the "NAND" gate 54 are connected to the outputs of the "OR" gates 52 , 53.
L'une (53) des portes "OU" est à ses entrées 80, 81 raccordée aux sorties 72 et 77 du décodeur 60, chacune sur l'un des circuits intégrés 60b , 60c précités affectés par exemple, l'un 60b a la mise en état de repos ou de fonctionner, l'autre 60c au contrôle en sortie. L'autre porte "OU" 52 est à ses entrées 82, 83 raccordée à la sortie de l'organe 34 et à la sortie 73 du circuit intégré 60b de mise en état.One (53) of the "OR" doors is at its entrances 80, 81 connected to the outputs 72 and 77 of the decoder 60, each on one of the aforementioned integrated circuits 60 b , 60 c for example, one 60 b in the idle or operating state, the other 60 c in the output control. The other "OR" gate 52 is at its inputs 82, 83 connected to the output of the member 34 and to the output 73 of the integrated circuit 60 b of readiness.
Dans cette variante de réalisation, le fonctionnement de l'étiquette est le suivant : Lorsque le doigt 47 de la plaquette est enfoncé dans l'étiquette (position de ce dernier lorsque l'étiquette est solidaire de l'article) un niveau logique "1" est présent sur une entrée de la porte "OU" 52 imposant un niveau logique "1" sur une des deux entrées de la porte "NAND" 54 ; la seconde entrée de la porte "NAND" 54 se trouvera au niveau logique "1" tant que le code émis soit par la caisse, soit par le portillon de sortie, sera inférieur ou égal au code programmé dans l'étiquette,In this variant embodiment, the operation of the label is as follows: When the finger 47 of the wafer is pressed into the label (position of the latter when the label is integral with the article) a logical level "1 "is present on an input of the gate" OR "52 imposing a logic level" 1 "on one of the two inputs of the gate" NAND "54; the second input of the "NAND" door 54 will be at logic level "1" as long as the code transmitted either by the cash register or by the exit gate, is less than or equal to the code programmed in the label,
Dans cette configuration la sortie de la porte "NAND" 54 sera au niveau logique "0", interdisant la mise sous tension de l'émeteur 7 porté par l'étiquette.In this configuration, the output of the "NAND" door 54 will be at logic level "0", preventing powering up of the transmitter 7 carried by the label.
Le fait d'enlever l'étiquette et donc le doigt 47 imposera un niveau logique "0" sur une entrée de la porte "OU" 52 ; sa sortie passera alors au niveau "0" qui, appliqué sur l'entrée de la porte "NAND" 54, fera basculer la sortie de cette dernière à "1" mettant par conséquence l'émetteur 7 en fonctionnement, d'où la commande de l'alarme.Removing the label and therefore finger 47 will impose a logic level "0" on an input of the "OR" door 52; its output will then go to level "0" which, applied to the input of the door "NAND" 54, will switch the output of the latter to "1" consequently putting the transmitter 7 in operation, hence the command of the alarm.
L'arrêt de l'alarme pourra se faire par la remise en place du doigt ce qui par un composant 51 d'un circuit 66 assure la remise à zéro des circuits intégrés 60b et 60c.The alarm stop can be done by replacing the finger by which a component 51 of a circuit 66 ensures the resetting of the integrated circuits 60 b and 60 c.
La détection de la présence de l'étiquette lors du passage à travers le portillon de sortie, impose en sortie de la porte "OU" 53 un niveau logique "0" qui, présenté sur une entrée de la porte "NAND" 54, imposera un niveau logique "1" en sortie de cette même porte "NAND" 54 provoquant la mise en service de l'émetteur 7.The detection of the presence of the label during the passage through the exit gate, imposes at the output of the "OR" gate 53 a logic level "0" which, presented on an input of the "NAND" gate 54, will impose a logic level "1" at the output of this same "NAND" gate 54 causing the commissioning of the transmitter 7.
Dans cette variante, les circuits 60a, 60b , 60c constituent le décodeur dont le rôle est de : a) reconnaître qu'il y a émission par un moyen extérieur (la sortie 73 du circuit 60b sera alors positionnée à "1") et, b) reconnaître si le code émis est correct ou non (c'est à dire s'il correspond au code pour lequel a été préréglée l'étiquette).In this variant, the circuits 60 a , 60 b, 60 c constitute the decoder whose role is to: a) recognize that there is emission by an external means (the output 73 of the circuit 60 b will then be positioned at "1") and, b) recognize if the transmitted code is correct or not (ie s' it corresponds to the code for which the label has been preset).
Sur le premier front montant de la donnée arrivant à l'entrée 70 du circuit 60b, la sortie de ce circuit 60b sera positionnée à "1" et gardera ce niveau tant qu'une remise à zéro n'aura pas été effectuée par la présence d'un niveau "1" sur son entrée 71 reliée au circuit 66 de remise à zéro. Le circuit 60c est identique au circuit 60b . Sa sortie 77 restera à "1" tant que le code émis ne sera pas strictement supérieur au code de préréglage. Dans ce dernier cas, cette sortie 77 basculera à "0" provoquant du même coup, la mise sous tension de l'émetteur 7 d' alarme.On the first rising edge of the data arriving at the input 70 of the circuit 60 b , the output of this circuit 60 b will be positioned at "1" and will keep this level until a reset has not been carried out by the presence of a level "1" on its input 71 connected to the reset circuit 66. Circuit 60 c is identical to circuit 60 b . Its output 77 will remain at "1" as long as the code issued is not strictly greater than the preset code. In the latter case, this output 77 will switch to "0" causing, at the same time, the powering of the alarm transmitter 7.
Cette mise sous tension sera limitée dans le temps par les composants 55 à 59 du circuit de remise à zéro 66. En effet, la détection d'une émission (passage de "0" à "1" de la sortie 73 du circuit 60b ) provoque la charge de la capacité 56 à travers la résistance 55.This power-up will be limited in time by the components 55 to 59 of the reset circuit 66. Indeed, the detection of an emission (passage from "0" to "1" of the output 73 of the circuit 60 b ) causes the charging of the capacitor 56 through the resistor 55.
Lorsque la charge de la capacité 56 correspond à un niveau logique "1" ce même niveau sera transmis sur les entrées 71, 79 des circuits intégrés 60b, 60c provoquant une remise à zéro du décodeur 60 ayant pour effet d'arrêter l'alarme. Ceci donne une excellente immunité aux parasites. Une seule configuration empêchera la remise à zéro du décodeur : elle correspond au cas où le code émis est égal au code programmé.When the load of the capacity 56 corresponds to a logic level "1", this same level will be transmitted on the inputs 71, 79 of the integrated circuits 60 b , 60 c causing a reset of the decoder 60 having the effect of stopping the alarm. This gives excellent immunity to parasites. A single configuration will prevent the reset of the decoder: it corresponds to the case where the transmitted code is equal to the programmed code.
En effet, lorsque les codes émis et programmé sont identiques, la sortie 75 du circuit 60a est positionnée à "0" imposant alors à la sortie de la porte "NAND" 57, un niveau logique "1" quelque soit l'état de charge de la capacité 56. Dans ce cas et seulement dans ce cas, le rétrait du doigt 47 ne provoquera pas la mise en service de l'émetteur 7.Indeed, when the transmitted and programmed codes are identical, the output 75 of the circuit 60 a is positioned at "0" then imposing at the output of the gate "NAND" 57, a logic level "1" whatever the state of charging of the capacity 56. In this case and only in this case, the withdrawal of the finger 47 will not cause the commissioning of the transmitter 7.
Bien entendu, d'autres modes de réalisation sont pos sibles sans pour cela sortir du cadre de l'invention.Of course, other embodiments are pos sibles without departing from the scope of the invention.
Cette étiquette trouve application non seulement dans des systèmes de détection de vols mais aussi dans tout système nécessitant la détection d'une présence et, par exemple, pour déterminer l'existence en stock d'articles donnés où le comptage d'articles qui défilent, par exemple un dispositif interroge l'étiquette qui transmet ses informations qui permettent de gérer le contrôle en cours. This label finds application not only in theft detection systems but also in any system requiring the detection of a presence and, for example, for determining the existence in stock of given items or the counting of items that pass by, for example a device interrogates the label which transmits its information which makes it possible to manage the control in progress.
