Description

Dispositif pour l'interrogation de transpondeurs Device for interrogating transponders
Domaine de l'inventionField of the invention
La présente invention concerne l'utilisation de transpondeurs RFID et plus particulièrement l'interrogation de tels transpondeurs au moyen d'un lecteur formé par un émetteur-récepteur dans des conditions normalement défavorables à l'interrogation.The present invention relates to the use of RFID transponders and more particularly the interrogation of such transponders by means of a reader formed by a transceiver under conditions normally unfavorable to the interrogation.
Etat de la technique En général, l'interrogation d'un transpondeur nécessite une proximité du lecteur, respectivement de son antenne si celle-ci est distante du lecteur, typiquement de l'ordre de quelques centimètres, faute de quoi, la lecture n'est plus possible. Il existe de nombreuses applications où le transpondeur ne peut être aisément approché par le lecteur et/ou de son antenne, par exemple lorsqu'il se trouve sur une face d'un objet alors que l'accès audit objet ne peut se faire que du côté d'une face opposée.State of the art In general, the interrogation of a transponder requires a proximity of the reader, respectively of its antenna if the latter is distant from the reader, typically of the order of a few centimeters, otherwise reading does not occur. is no longer possible. There are many applications where the transponder can not be easily approached by the reader and / or its antenna, for example when it is on a face of an object while access to said object can be done only from the side of an opposite side.
Objectifs de l'inventionObjectives of the invention
L'invention vise à pouvoir communiquer avec un transpondeur à une distance supérieure à la distance normalement possible.The invention aims to be able to communicate with a transponder at a distance greater than the distance normally possible.
Plus précisément, l'invention vise à pouvoir interroger un transpondeur disposé sur un objet, métallique ou non, par exemple une bouteille de gaz, à partir de n'importe quel point situé sur le pourtour de l'objet.More specifically, the invention aims to interrogate a transponder disposed on an object, metal or not, for example a gas cylinder, from any point on the periphery of the object.
Résumé de l'inventionSummary of the invention
A cet effet, l'invention concerne un dispositif pour l'interrogation de transpondeurs associés à des objets, à partir d'un lecteur comprenant un émetteur-récepteur, ledit dispositif comprenant un fil conducteur de couplage formant une boucle fermée qui est adaptée pour être disposée dans l'environnement d'un objet tout en étant solidaire de cet objet, ladite boucle étant par ailleurs adaptée pour être placée en regard d'un l'émetteur-récepteur et couplée inductivement à l'antenne de celui-ci; ladite boucle comprenant en outre une portion formant un enroulement constitué d'au moins une spire; ledit enroulement étant adapté de manière à pouvoir être couplé inductivement avec un transpondeur.To this end, the invention relates to a device for interrogating transponders associated with objects, from a reader comprising a transceiver, said device comprising a coupling conductor wire forming a closed loop which is adapted to be disposed in the environment of an object while being integral with this object, said loop being further adapted to be placed opposite a transceiver and inductively coupled to the antenna thereof; said loop further comprising a portion forming a winding consisting of at least one turn; said winding being adapted to be inductively coupled with a transponder.
Dans le présent texte, par "boucle", on entend un fil conducteur dont les extrémités se rejoignent. La boucle peut avoir n'importe quelle géométrie, p.ex. circulaire, ovale, croissant, présenter des angles aigus ou obtus, etc.. La boucle peut également se conformer ou pas à l'objet qui lui est associé. Plus généralement, la boucle peut être confondue dans une surface plane ou courbe.In the present text, "loop" means a conductive thread whose ends meet. The loop may have any geometry, eg circular, oval, crescent, have sharp or obtuse angles, etc. The loop may also conform or not to the object associated with it. More generally, the loop can be confused in a flat or curved surface.
Le fil conducteur et la boucle qu'il forme peuvent être qualifié respectivement de fil et boucle de couplage. Par effet inductif entre le transpondeur et l'enroulement, un signal électromagnétique peut être transmis entre la boucle et le transpondeur.The conducting wire and the loop that it forms can be described respectively as a wire and a coupling loop. By inductive effect between the transponder and the winding, an electromagnetic signal can be transmitted between the loop and the transponder.
La configuration selon l'invention permet d'interroger un transpondeur en disposant le lecteur, respectivement son antenne si elle est distante du lecteur, à proximité du fil conducteur.The configuration according to the invention makes it possible to interrogate a transponder by arranging the reader, respectively its antenna if it is distant from the reader, close to the conducting wire.
Selon un premier mode de réalisation de l'invention, l'enroulement est spirale de manière à pouvoir entourer un transpondeur du type "métal rod". Par "métal rod", on entend un transpondeur formé d'un bobinage qui entoure un barreau métallique, p.ex. en ferrite, le tout étant de préférence encapsulé dans du verre.According to a first embodiment of the invention, the winding is spiral so as to surround a transponder of the "metal rod" type. By "metal rod" is meant a transponder formed of a coil which surrounds a metal bar, eg ferrite, the whole being preferably encapsulated in glass.
Selon un deuxième mode de réalisation de l'invention, l'enroulement se présente sous la forme d'un anneau adapté de manière à être couplé inductivement avec l'antenne d'un transpondeur de type "air coil".According to a second embodiment of the invention, the winding is in the form of a ring adapted to be coupled inductively with the antenna of an "air coil" type transponder.
L'anneau peut être formé d'une ou plusieurs spires.The ring may be formed of one or more turns.
Par "air coil", on entend une configuration où la boucle du transpondeur se situe approximativement dans un plan parallèle à celui dans lequel se trouve l'enroulement. Dans ce cas, l'enroulement n'entoure donc pas le transpondeur mais se trouve à proximité de celui-ci, à une distance autorisant le couplage inductif entre les deux éléments. Selon une variante de l'invention, la boucle est adaptée pour contacter directement ledit objet.By "air coil" is meant a configuration where the transponder loop is approximately in a plane parallel to that in which the winding is located. In this case, the winding therefore does not surround the transponder but is close to it, at a distance allowing the inductive coupling between the two elements. According to a variant of the invention, the loop is adapted to directly contact said object.
Selon une autre variante, la boucle est adaptée pour être maintenue à une certaine distance de l'objet, la distance se situant de préférence entre 2 et 8 mm.According to another variant, the loop is adapted to be maintained at a distance from the object, the distance preferably being between 2 and 8 mm.
Selon un mode de réalisation particulièrement avantageux de l'invention, la boucle est adaptée pour entourer une portion de l'objet auquel est associé le transpondeur, cette portion pouvant par exemple être le col d'une bouteille de gaz.According to a particularly advantageous embodiment of the invention, the loop is adapted to surround a portion of the object which is associated with the transponder, this portion may for example be the neck of a gas cylinder.
La boucle peut entourer complètement ou partiellement la portion de l'objet.The loop can completely or partially surround the portion of the object.
L'invention concerne également un ensemble constitué d'une boucle telle que définie précédemment et d'un transpondeur.The invention also relates to an assembly consisting of a loop as defined above and a transponder.
Si le transpondeur est du type "métal rod", l'enroulement se présente de préférence sous forme de spirale qui entoure le transpondeur.If the transponder is of the "metal rod" type, the winding is preferably in the form of a spiral which surrounds the transponder.
Si le transpondeur est du type "air coil", l'enroulement se présente de préférence sous la forme d'un anneau disposé selon un plan parallèle à celui dans lequel se trouve l'antenne du transpondeur, les deux éléments étant disposés coaxialement et ayant sensiblement le même diamètre.If the transponder is of the "air coil" type, the winding is preferably in the form of a ring disposed in a plane parallel to that in which the antenna of the transponder is located, the two elements being arranged coaxially and having substantially the same diameter.
L'invention concerne également une bouteille, avantageusement une bouteille de gaz, qui comprend un dispositif tel que défini précédemment et un transpondeur rendu solidaire de la bouteille au niveau de son col, le transpondeur étant disposé de manière à pouvoir être couplé inductivement avec l'enroulement.The invention also relates to a bottle, advantageously a gas bottle, which comprises a device as defined above and a transponder secured to the bottle at its neck, the transponder being arranged so as to be inductively coupled with the winding.
Selon une première variante, boucle entoure complètement le col.According to a first variant, the loop completely surrounds the neck.
Selon une deuxième variante, la boucle entoure partiellement le col. Selon un mode de réalisation particulièrement intéressant, la bouteille comprend une couronne partiellement ouverte qui entoure partiellement le col, la couronne étant formée de préférence d'un matériau composite et incorpore la boucle et le transpondeur.According to a second variant, the loop partially surrounds the neck. According to a particularly advantageous embodiment, the bottle comprises a partially open crown which partially surrounds the neck, the ring being preferably formed of a composite material and incorporates the loop and the transponder.
L'invention concerne enfin une méthode d'interrogation d'un transpondeur rendu solidaire d'un objet. Le méthode se caractérise en ce que l'interrogation est réalisée par l'intermédiaire d'une boucle telle que définie précédemment.The invention finally relates to a method of interrogating a transponder made integral with an object. The method is characterized in that the interrogation is carried out via a loop as defined above.
De préférence, le transpondeur et le fil conducteur sont logés dans une protection en matière plastique, p.ex. une gaine, afin de résister aux chocs et aux conditions d'exploitation de l'objet. La protection est fixée sur l'objet.Preferably, the transponder and the conductive wire are housed in a plastic protection, eg a sheath, in order to withstand shocks and operating conditions of the object. The protection is fixed on the object.

La figure 1 présente un conteneur 1 , métallique ou non, p.ex. une bouteille de gaz, qui comprend un epaulement 7 et un col 2 comportant une bride, le col 2 étant surmonté d'une vanne à gaz (non-illustrée) protégée par un couvercle 3. Un transpondeur de type "métal rod" 4, connu en soi, est fixé sur le col 2. Un fil conducteur 5 formant une boucle est disposé autour du col 2. Autour du transpondeur 4, le fil conducteur 5 forme un enroulement spirale 6.FIG. 1 shows a container 1, metallic or not, eg a gas bottle, which comprises a shoulder 7 and a neck 2 comprising a flange, the neck 2 being surmounted by a gas valve (not shown) protected by a cover 3. A transponder of "metal rod" type 4, known per se, is fixed on the neck 2. A conductive wire 5 forming a loop is arranged around the neck 2. Around the transponder 4, the conductive wire 5 forms a spiral winding 6.
Le fil conducteur 5 est également fixé à la bouteille. De préférence, le fil conducteur 5 et le transpondeur 4 sont logés dans une protection plastique (non illustrée).The conductive wire 5 is also attached to the bottle. Preferably, the conducting wire 5 and the transponder 4 are housed in a plastic cover (not shown).
Il n'existe pas de contact mécanique entre l'enroulement spirale 6 et le transpondeur 4. Cependant, ces deux éléments étant relativement proches, un signal électromagnétique peut être transmis d'un élément à l'autre par effet inductif.There is no mechanical contact between the spiral winding 6 and the transponder 4. However, these two elements being relatively close, an electromagnetic signal can be transmitted from one element to another by inductive effect.
Il est dès lors possible d'interroger le transpondeur 4 en disposant un lecteur, voire son antenne si celle-ci est distante du lecteur, à proximité du fil conducteur 5, en un endroit relativement éloigné du transpondeur 4. Le mode de réalisation illustré sur la figure 2 est très similaire à celui de la figure 1 , il diffère uniquement en ce que le transpondeur est du type "air coil". Le transpondeur est constitué d'un chip 9 et d'une antenne de forme annulaire 8, le tout étant fixé sur le col 2 de la bouteille.It is therefore possible to interrogate the transponder 4 by arranging a reader, or even its antenna if it is distant from the reader, near the conductor wire 5, at a location relatively remote from the transponder 4. The embodiment illustrated in FIG. 2 is very similar to that of FIG. 1, it differs only in that the transponder is of the "air coil" type. The transponder consists of a chip 9 and an annular antenna 8, the whole being attached to the neck 2 of the bottle.
La boucle 5 comporte un enroulement formant un anneau 10 constitué d'une ou plusieurs spires. L'anneau 10 et l'antenne 8 du transpondeur sont disposés dans des plans parallèles. En outre, ces deux éléments se situent sur même axe.The loop 5 comprises a winding forming a ring 10 consisting of one or more turns. The ring 10 and the antenna 8 of the transponder are arranged in parallel planes. In addition, these two elements are on the same axis.
La figure 3 illustre un exemple où l'ensemble constitué par la boucle 5 et le transpondeur 4 (de type "métal rod" dans cet exemple) sont intégrée dans une couronne 11 qui entoure partiellement une valve 13 disposée sur le col d'une bouteille de gaz. La couronne 11 comporte deux orifices 12 formant des poignées.FIG. 3 illustrates an example where the assembly formed by the loop 5 and the transponder 4 (of the "metal rod" type in this example) are integrated in a ring 11 which partially surrounds a valve 13 disposed on the neck of a bottle gas. The ring 11 has two orifices 12 forming handles.
A noter que la boucle peut en fait être formée de plusieurs boucles, chacune d'entre elles partant du transpondeur.Note that the loop may in fact be formed of several loops, each of them starting from the transponder.
Il va de soi que l'invention ne se limite pas aux exemples précités. Le transpondeur peut par exemple se situer ailleurs que sur le col, p.ex. sur l'épaulement, sur le couvercle ou sur la face latérale de la bouteille.It goes without saying that the invention is not limited to the above examples. The transponder may for example be located elsewhere than on the neck, eg on the shoulder, on the lid or on the side face of the bottle.
De même, l'invention peut également être utilisée avec d'autres objets et/ou dans d'autres domaine que le stockage du gaz. Likewise, the invention can also be used with other objects and / or in other fields than gas storage.
