La bouteille 6 de fluide sous pression représentée schématiquement et partiellement à la figure 1 comprend classiquement un orifice dans lequel est monté un robinet 7.The pressurized fluid bottle 6 shown diagrammatically and partially in figure 1 Conventionally comprises an orifice in which a valve 7 is mounted.

Le robinet 7 abrite un circuit 17 de fluide comprenant au moins une vanne.The valve 7 houses a fluid circuit 17 comprising at least one valve.

La bouteille 6 comporte de plus un chapeau 1 de protection du robinet 7 monté sur l'extrémité supérieure de la bouteille 6. Le chapeau 1 comprend une structure rigide délimitant un volume de protection autour du robinet 7. Cette structure rigide comprend une extrémité inférieure 4 fixée sur l'extrémité supérieure de la bouteille 6 (par exemple par vissage ou serrage) et une première paroi 2 formant une portion tubulaire centrale.The bottle 6 further comprises a protective cap 1 for the tap 7 mounted on the upper end of the bottle 6. The cap 1 comprises a rigid structure defining a protective volume around the tap 7. This rigid structure comprises a lower end 4 fixed to the upper end of the bottle 6 (for example by screwing or tightening) and a first wall 2 forming a central tubular portion.

Cette portion tubulaire, par exemple cylindrique, s'étend entre d'une part l'extrémité inférieure 4 et, d'autre part, une extrémité supérieure 12 ouverte délimitant un orifice 5 supérieur d'accès au volume interne de la portion tubulaire et abritant le robinet 7.This tubular portion, for example cylindrical, extends between on the one hand the lower end 4 and, on the other hand, an open upper end 12 delimiting an upper orifice 5 for access to the internal volume of the tubular portion and housing the tap 7.

La portion tubulaire délimitée par la première paroi 2 peut être ajourée ou non.The tubular portion delimited by the first wall 2 may or may not be perforated.

Le chapeau 1 peut être constitué de métal et/ou de fonte et/ou de plastique...The cap 1 can be made of metal and / or cast iron and / or plastic ...

La bouteille 6 est munie également d'au moins un organe 10 électronique de communication et de stockage de données interrogeable à distance sans fil. Cet organe 10 électronique de communication est de préférence disposé dans le chapeau 1.The bottle 6 is also provided with at least one electronic device 10 for communication and storage of data that can be interrogated wirelessly. This electronic communication device 10 is preferably placed in the cap 1.

Selon une particularité avantageuse, cet organe 10 électronique comprend par exemple une antenne 11 annulaire disposée concentriquement à l'ouverture 3 dans la bordure circulaire de l'extrémité supérieure 12 de la première paroi 2. C'est-à-dire que l'antenne 11 peut être circulaire et située au niveau de l'extrémité de la première paroi 2 de façon concentrique à l'ouverture 5 (dans la bordure circulaire délimitant l'ouverture 5).According to an advantageous feature, this electronic member 10 comprises for example an annular antenna 11 arranged concentrically with the opening 3 in the circular edge of the upper end 12 of the first wall 2. That is to say that the antenna 11 may be circular and located at the end of the first wall 2 concentrically with the opening 5 (in the circular border defining the opening 5).

De cette façon l'antenne 11 est aisément accessible notamment pour un organe qui viendrait se raccorder sur le robinet 7 au travers de l'ouverture 5 (cf. ci-après en référence notamment à la figure 5).In this way, the antenna 11 is easily accessible, in particular for a member which would be connected to the valve 7 through the opening 5 (see below with particular reference to the figure 5 ).

De préférence, l'antenne 11 comprend par exemple un bobinage classique de fil conducteur. L'antenne 11 peut comprendre un fil conducteur isolé et/ou un circuit imprimé souple ou rigide. De plus, de préférence également l'organe 10 électronique de communication et de stockage de données comprend une puce 15 électronique comprenant notamment une mémoire de données, la puce 15 étant raccordée à l'antenne 11 (cf. figure 2).Preferably, the antenna 11 comprises for example a conventional coil of conductive wire. The antenna 11 may include an insulated conductor wire and / or a flexible or rigid printed circuit. In addition, also preferably the electronic device 10 for communication and data storage comprises an electronic chip 15 comprising in particular a data memory, the chip 15 being connected to the antenna 11 (cf. figure 2 ).

La puce 15 électronique peut comporter une zone de mémoire dans laquelle sont stockés un ou plusieurs identifiants de la bouteille 6, par exemple du type alphanumériques. Bien entendu, cette mémoire peut également contenir d'autres informations concernant la bouteille 6 et/ le gaz qu'elle contient (pression de service, volume nominal, date de ré-épreuve, nature du gaz...).The electronic chip 15 may include a memory area in which are stored one or more identifiers of the bottle 6, for example of the alphanumeric type. Of course, this memory can also contain other information concerning the bottle 6 and / the gas it contains (operating pressure, nominal volume, date of retest, nature of the gas, etc.).

La puce 15 peut être alimentée en énergie par le champ magnétique généré/capté par le bobinage 11. Cette puce 15 est configurée également pour assurer le décodage de l'information envoyée ou reçue sans fil (véhiculée par les modulations du champ magnétique par exemple).The chip 15 can be supplied with energy by the magnetic field generated / picked up by the coil 11. This chip 15 is also configured to ensure the decoding of the information sent or received wirelessly (conveyed by the modulations of the magnetic field for example) .

Selon une particularité avantageuse, l'antenne 11 et la puce 15 sont logées dans un boîtier annulaire 14 (de préférence en plastique) et sont noyées dans de la résine de maintien coulée liquide et qui est durcie pour figer l'ensemble.According to an advantageous feature, the antenna 11 and the chip 15 are housed in an annular casing 14 (preferably made of plastic) and are embedded in liquid cast holding resin which is hardened to fix the assembly.

Cet agencement assure la tenue mécanique de l'antenne 11 et permet de réduire le couplage électrique et magnétique entre cette dernière et son environnement. De préférence le boîtier 14 présente de préférence une ouverture permettant de le positionner au niveau de l'extrémité supérieure du chapeau 1.This arrangement ensures the mechanical strength of the antenna 11 and makes it possible to reduce the electrical and magnetic coupling between the latter and its environment. Preferably, the housing 14 preferably has an opening allowing it to be positioned at the level of the upper end of the cap 1.

Cet organe 10 électronique de communication et de stockage de données est logé de préférence dans une rainure 140 conjuguée (circulaire dans cet exemple) formée au niveau de l'extrémité supérieure 12 de la première paroi 2. En position montée, de préférence l'organe 10 électronique de communication affleure ou est en retrait par rapport à cette extrémité supérieure de la première paroi 2. Ce positionnement permet à la fois une bonne aptitude à la communication et une protection mécanique et électrique de l'organe 10 électronique de communication.This electronic communication and data storage member 10 is preferably housed in a mating groove 140 (circular in this example) formed at the upper end 12 of the first wall 2. In the mounted position, preferably the member 10 communication electronics are flush with or are set back with respect to this upper end of the first wall 2. This positioning allows both good communication capability and mechanical and electrical protection of the electronic communication device 10.

Comme illustré à la figure 6 ou à la figure 4, la rainure 140 peut être délimitée au moins en partie par une bague 22 de maintien assemblée sur l'extrémité supérieure de la première paroi 2 du chapeau 1.As shown in figure 6 or at the figure 4 , the groove 140 may be delimited at least in part by a retaining ring 22 assembled on the upper end of the first wall 2 of the cap 1.

Comme illustré aux figures 3, 4 et 6, l'organe 10 électronique de communication et de stockage de données peut être bloqué transversalement et verticalement dans la rainure 140 via des butées respectives (les directions verticales et transversales font référence aux axes du robinet lorsqu'il est monté sur une bouteille disposée verticalement).As shown in figures 3 , 4 and 6 , the electronic communication and data storage unit 10 can be blocked transversely and vertically in the groove 140 via respective stops (the vertical and transverse directions refer to the axes of the valve when it is mounted on a bottle arranged vertically) .

Dans la réalisation de la figure 6, la rainure 140 est délimitée par deux demi-coques 20, 22 assemblées dans plan de l'organe 10. C'est-à-dire que les deux demi-coques 20 peuvent comporter respectivement des demi-rainures creusées en arc de cercle qui viennent accueillir respectivement les deux moitiés de l'anneau formé par l'organe 10. Ces deux demi-coques peuvent former tout ou partie de la première paroi 2 du chapeau 1.In carrying out the figure 6 , the groove 140 is delimited by two half-shells 20, 22 assembled in the plane of the member 10. That is to say that the two half-shells 20 may respectively comprise half-grooves hollowed out in an arc of a circle which respectively receive the two halves of the ring formed by the member 10. These two half-shells can form all or part of the first wall 2 of the cap 1.

Lors de l'assemblage l'organe 10 électronique de communication peut être scellé dans le corps du chapeau 1. Par exemple, l'organe 10 électronique possède une section en forme de L ou de T et les logements correspondants présentent un profil complémentaire.During assembly, the electronic communication device 10 can be sealed in the body of the cap 1. For example, the electronic device 10 has an L-shaped or T-shaped section and the corresponding housings have a complementary profile.

Dans la configuration des figures 1 et 4 (pas de dispositif raccordé sur le robinet 7), le positionnement de l'organe 10 électronique est tel qu'il est possible de lui approcher un dispositif muni d'un système de communication sans fil (NFC notamment), par exemple un téléphone portable ou un lecteur industriel, à son contact ou à quelques millimètres (par exemple 30 mm). Ce dispositif (téléphone ou autre) permet d'échanger de l'information avec l'organe 10 électronique via un couplage magnétique adéquat. L'organe 10 électronique et/ou le chapeau 1 peuvent comprendre une ou de inclusions de matériau(x) à forte perméabilité magnétique (par exemple un matériau à base de ferrite, c'est-à-dire ayant une bonne perméabilité et étant relativement mauvais conducteur) pour concentrer les lignes de champ magnétique vers l'antenne 24 de lecture d'un organe de communication conjugué extérieur (cf. ci-après) et pour limiter l'effet des courants de Foucault dans le métal environnant. Ces inclusions pourront avantageusement avoir une forme de logement dont la section transverse forme un U ouvert vers la direction de communication (c'est-à-dire vers l'extérieur et vers le haut lorsque le chapeau est dans une position verticale selon la figure 1 notamment).In the configuration of figures 1 and 4 (no device connected to the tap 7), the positioning of the electronic device 10 is such that it is possible to bring a device equipped with a wireless communication system (NFC in particular), for example a mobile phone, to it. or an industrial reader, in contact with it or within a few millimeters (for example 30 mm). This device (telephone or other) makes it possible to exchange information with the electronic device via an adequate magnetic coupling. The electronic organ and / or the cap 1 may comprise one or more inclusions of material (s) with high magnetic permeability (for example a material based on ferrite, i.e. having good permeability and being relatively poor conductor) to concentrate the magnetic field lines towards the reading antenna 24 of an external conjugate communication device (see below) and to limit the effect of eddy currents in the surrounding metal. These inclusions may advantageously have a housing shape, the cross section of which forms a U open towards the direction of communication (that is to say towards the outside and upwards when the cap is in a vertical position according to the figure 1 especially).

Ceci facilite l'écoulement des lignes de champ vers l'antenne de lecture 24 adjacente avec laquelle la communication est réalisée. Le fil de l'antenne est placé avantageusement à l'intérieur du U.This facilitates the flow of the field lines to the adjacent read antenna 24 with which communication is made. The antenna wire is advantageously placed inside the U.

La figure 5 illustre un exemple de coopération d'un tel organe 10 de communication avec un organe 24 de communication conjugué d'un appareil (robinet ou autre) sélectivement raccordable au robinet 7 de la bouteille 6.The figure 5 illustrates an example of cooperation of such a communication member 10 with a communication member 24 combined with a device (valve or other) selectively connectable to the valve 7 of the bottle 6.

Cet appareil constitue par exemple un organe de remplissage et/ou soutirage comprenant un corps 20 connectable de manière amovible au robinet 7 de la bouteille 6. Ce corps 20 abrite un organe 123 pousse-clapet mobile (pour ouvrir le circuit 17 c'est-à-dire pour ouvrir au moins une vanne de ce circuit 17).This apparatus constitutes for example a filling and / or withdrawal member comprising a body 20 which can be connected in a removable manner to the valve 7 of the bottle 6. This body 20 houses a movable valve pushing member 123 (to open the circuit 17 that is that is to say to open at least one valve of this circuit 17).

Le corps 20 abrite également un circuit 23 de fluide destiné à être raccordé au circuit 17 du robinet 7 de la bouteille 6.The body 20 also houses a fluid circuit 23 intended to be connected to the circuit 17 of the valve 7 of the bottle 6.

Le corps 20 de l'organe de remplissage et/ou soutirage comprend une extrémité munie d'une tête 21 de raccordement comprenant des organes d'accrochage conjugués de l'extrémité du robinet 7 pour coopérer en accrochage (connexion rapide notamment) avec ce dernier. Le corps 20 comprend en outre un organe 24 électronique de communication et éventuellement de stockage de données interrogeable à distance sans fil. Par exemple, la tête 21 de raccordement fait saillie sur l'extrémité du corps 20 par rapport un organe 24 électronique.The body 20 of the filling and / or withdrawal member comprises an end provided with a connection head 21 comprising coupling members coupled to the end of the valve 7 to cooperate in hooking (particularly rapid connection) with the latter. . The body 20 further comprises an electronic member 24 for communication and possibly for storing data that can be interrogated wirelessly. For example, the connection head 21 projects from the end of the body 20 relative to an electronic member 24.

L'organe 24 électronique de communication est situé concentriquement autour de ladite tête 21 de raccordement de sorte que, lorsque l'organe de remplissage et/ou de soutirage est raccordé sur le robinet, les organes 24, 10 électroniques de communication (antennes conjuguées) sont disposés en vis à vis dans deux plans parallèles espacés d'une distance comprise entre 0,5cm et 5cm. De cette façon, l'échange sans fil de données peut être réalisé entre le robinet 7 et l'organe de remplissage et/ou de soutirage. De préférence, l'organe 24 électronique de communication 24 est une antenne circulaire qui a un diamètre proche ou identique au diamètre de l'organe 10 de communication (antenne 11 conjuguée) du chapeau 1. En position raccordée de l'organe de remplissage sur le robinet ces deux antennes 10 24 sont très proches et notamment superposées pour assurer un bon couplage magnétique (0,1 à 2cm par exemple).The electronic communication member 24 is located concentrically around said connection head 21 so that, when the filling and / or withdrawal member is connected to the valve, the electronic communication members 24, 10 (conjugate antennas) are arranged opposite each other in two parallel planes spaced at a distance between 0.5cm and 5cm. In this way, the wireless exchange of data can be carried out between the tap 7 and the filling and / or withdrawal member. Preferably, the electronic communication member 24 is a circular antenna which has a diameter close to or identical to the diameter of the communication member 10 (conjugate antenna 11) of the cap 1. In the connected position of the filling member on the tap, these two antennae 10 24 are very close and in particular superimposed to ensure good magnetic coupling (0.1 to 2 cm for example).

L'organe 24 électronique de communication peut comporter une carte 25 électronique qui peut être alimentée par une source d'énergie propre, comme une batterie ou une pile, ou être connectée à une source d'énergie distante. La carte 25 électronique peut-être reliée au bobinage 21 par un câblage dont la longueur est de préférence limitée à une dizaine de centimètres. Cette organe 24 électronique (et notamment sa carte) peut être configuré pour générer un courant électrique modulé dans le bobinage 11 pour créer un champ magnétique modulé assurant la communication d'information et d'énergie avec l'antenne 11 de la bouteille 6 par couplage magnétique.The electronic communication device 24 can include an electronic card 25 which can be powered by a clean energy source, such as a battery or a cell, or be connected to a remote energy source. The electronic card 25 may be connected to the coil 21 by a wiring whose length is preferably limited to about ten centimeters. This electronic member 24 (and in particular its card) can be configured to generate a modulated electric current in the coil 11 to create a modulated magnetic field. providing information and energy communication with the antenna 11 of the bottle 6 by magnetic coupling.

Par ailleurs l'organe électronique 24 (antenne) peut être réalisé soit sous la forme d'un circuit imprimé, soit sous la forme d'au moins une bobine de fil métallique isolé, soit sous forme d'un circuit imprimé souple. Dans ces trois cas, ladite antenne 24 peut avantageusement être surmoulée dans une pièce plastique de protection et d'aspect. Dans le cas d'une antenne sur circuit souple, ledit circuit peut comporter une partie allongée permettant la connexion sur la carte électronique 25. Le cheminement du circuit est de préférence alterné pour limiter le couplage magnétique avec l'extérieur.Furthermore, the electronic device 24 (antenna) can be produced either in the form of a printed circuit, or in the form of at least one coil of insulated metal wire, or in the form of a flexible printed circuit. In these three cases, said antenna 24 can advantageously be overmolded in a protective plastic part and appearance. In the case of an antenna on a flexible circuit, said circuit may include an elongated part allowing connection to the electronic card 25. The path of the circuit is preferably alternated in order to limit the magnetic coupling with the outside.

Comme décrit précédemment pour l'organe 10 électronique du chapeau 1, l'organe 24 électronique de communication et/ou le corps 20 peut comprendre également une ou de inclusions de matériau(x) à forte perméabilité magnétique pour concentrer les lignes de champ magnétique vers l'antenne 10 et pour limiter l'effet des courants de Foucault dans le métal environnant. Ces inclusions pourront également avoir une forme de logement dont la section transverse forme un U ouvert vers la direction de communication (vers le bas lorsque le corps 20 est en position verticale notamment selon la figure 5). L'ouverture du U est ainsi tournée vers l'organe 10 électronique (antenne) avec la communication est réalisée).As previously described for the electronic component 10 of the cap 1, the electronic communication component 24 and / or the body 20 may also include one or more inclusions of material (s) with high magnetic permeability to concentrate the magnetic field lines towards antenna 10 and to limit the effect of eddy currents in the surrounding metal. These inclusions may also have a housing shape, the cross section of which forms a U open towards the direction of communication (downwards when the body 20 is in a vertical position, in particular according to the figure 5 ). The opening of the U is thus turned towards the electronic device (antenna) with the communication being carried out).

Comme précédemment, ceci facilite l'écoulement des lignes de champ vers l'antenne de lecture 10 adjacente avec laquelle la communication est réalisée. Le fil de l'antenne est placé avantageusement à l'intérieur du U.As before, this facilitates the flow of the field lines to the adjacent read antenna 10 with which communication is effected. The antenna wire is advantageously placed inside the U.

Ce dispositif 24, 25 électronique assure également le décodage et le stockage de l'information envoyée sans fil par l'organe 10 électronique du chapeau 1. De préférence, cet organe 24 électronique est configuré pour réaliser une communication bidirectionnelle d'information avec d'autres cartes électroniques présentes dans le chapeau 1.This electronic device 24, 25 also ensures the decoding and storage of the information sent wirelessly by the electronic device 10 of the cap 1. Preferably, this electronic device 24 is configured to carry out a two-way communication of information with other electronic boards present in cap 1.

En position raccordée, les deux organes 10, 24 de communication (antennes conjuguées adjacentes) permettent une détection/lecture/communication sans fil qu'elle que soit l'orientation relative angulaire du corps 20 par rapport au chapeau 1 autour d'un axe vertical central de la bouteille.In the connected position, the two communication members 10, 24 (adjacent conjugate antennas) allow wireless detection / reading / communication regardless of the angular relative orientation of the body 20 with respect to the cap 1 about a vertical axis central of the bottle.

Cet organe 24 électronique peut comporter notamment un module d'affichage graphique, un module de télécommunication,...This electronic member 24 may in particular include a graphic display module, a telecommunications module, etc.

L'organe 10 électronique de communication et de stockage de données de la bouteille 6 peut être configuré pour communiquer selon une au moins des déclinaisons suivantes de la technologie de communication radio-fréquence RFID (« Radio-Frequency Identification) : RFID Ultra-Haute Fréquence (« RFID UHF »), RFID Haute-Fréquence (« RFID HF »), suivant un des standards NFC dédiés aux Communications en Champ Proche (« RFID NFC » : « Near Field Communication », par exemple selon la norme ISO 15693).The electronic communication and data storage device 10 of the bottle 6 can be configured to communicate according to at least one of the following variations of the radio-frequency communication technology RFID ("Radio-Frequency Identification): Ultra-High Frequency RFID ("UHF RFID"), High-Frequency RFID ("HF RFID"), according to one of the NFC standards dedicated to Near Field Communications ("NFC RFID": "Near Field Communication", for example according to the ISO 15693 standard).

La technologie « NFC » désigne ici au sens large une communication par couplage en champ proche dans les bandes HF ou UHF notamment, mais pas exclusivement celui des normes ISO 14443 et ISO 15693. Le « NFC » est un standard ISO 14443 qui est une des technologies RFID. Bien entendu, l'invention peut concerner d'autres fréquences et/ou standards. L'invention peut concerner des fréquences de quelques KHz à 1 GHz“NFC” technology here in the broad sense designates near-field coupling communication in the HF or UHF bands in particular, but not exclusively that of the ISO 14443 and ISO 15693 standards. “NFC” is an ISO 14443 standard which is one of the standards. RFID technologies. Of course, the invention can relate to other frequencies and / or standards. The invention may relate to frequencies from a few KHz to 1 GHz

La technologie RFID est une technologie de communication sans fil entre un dispositif interrogateur, ou lecteur, et un appareil interrogateur, ou « tag » (transpondeur). Dans son principe général, le lecteur apporte de l'énergie et de l'information au « tag » sous forme d'un champ électrique, magnétique ou électromagnétique modulé ; le « tag » renvoie de l'information au lecteur en modulant les caractéristiques de son couplage avec le champ généré par le lecteur, ce qui induit un retour d'énergie vers le lecteur, modulé en fonction de l'information à transmettre.RFID technology is a wireless communication technology between an interrogator device, or reader, and an interrogator device, or "tag" (transponder). In general, the reader brings energy and information to the "tag" in the form of a modulated electric, magnetic or electromagnetic field; the “tag” returns information to the reader by modulating the characteristics of its coupling with the field generated by the reader, which induces a return of energy to the reader, modulated according to the information to be transmitted.

La déclinaison UHF se caractérise par une bande de fonctionnement entre 860 et 960 MHz, une distance maximale entre le lecteur et le tag de l'ordre de 10m, l'émission par le lecteur d'une onde électromagnétique se propageant entre autres vers le « tag », et rétrodiffusée par celui-ci par adaptation de ses paramètres d'antenne. Cette déclinaison est bien adaptée à la logistique de lots d'objets.The UHF variation is characterized by an operating band between 860 and 960 MHz, a maximum distance between the reader and the tag of the order of 10m, the emission by the reader of an electromagnetic wave propagating among others towards the " tag ”, and backscattered by it by adapting its antenna parameters. This variation is well suited to the logistics of batches of objects.

La déclinaison HF se caractérise par une bande de fonctionnement centrée sur 13.56 MHz, pour une distance maximale entre le lecteur et le tag de l'ordre de quelque dizaine de centimètres à quelques mètres. Le couplage entre le lecteur et le « tag » se fait en général au moyen d'un champ magnétique, typiquement au moyen de deux bobinages adaptés en impédance, l'un sur le « tag » et l'autre sur le lecteur, le « tag » pouvant adapter son impédance pour transmettre de l'information au lecteur par modification du couplage entre les deux dispositifs. Cette déclinaison est bien adaptée à la logistique objet par objet, et aux transactions sécurisées (identification, payement...) car l'information se propage peu autour du système lecteur-« tag » grâce au couplage théoriquement purement magnétique.The HF variation is characterized by an operating band centered on 13.56 MHz, for a maximum distance between the reader and the tag of the order of ten centimeters to a few meters. The coupling between the reader and the "tag" is generally done by means of a magnetic field, typically at means of two coils adapted in impedance, one on the “tag” and the other on the reader, the “tag” being able to adapt its impedance to transmit information to the reader by modifying the coupling between the two devices. This variation is well suited to object-by-object logistics, and to secure transactions (identification, payment, etc.) because information does not propagate much around the reader-“tag” system thanks to the theoretically purely magnetic coupling.

Le « tag » est en général un dispositif passif, puisque toute son énergie est apportée par le lecteur. Des systèmes dits « semi-passifs » ou « semi-actifs » existent, dans lequel le « tag » embarque une source d'énergie utilisée pour alimenter son électronique embarquée, mais la communication se fait toujours par adaptation/désadaptation du canal de couplage, sans émission d'énergie par le tag. Enfin, il existe des tags « actifs » qui sont capables, au moyen d'une source d'énergie embarqué, d'émettre un rayonnement à destination du lecteur (où d'agir à la fois comme « tag » et lecteur).The “tag” is generally a passive device, since all of its energy is contributed by the reader. So-called “semi-passive” or “semi-active” systems exist, in which the “tag” embeds an energy source used to supply its on-board electronics, but communication is always done by adaptation / mismatching of the coupling channel, without energy emission by the tag. Finally, there are “active” tags which are capable, by means of an onboard energy source, of emitting radiation to the reader (or of acting both as “tag” and reader).

En plus des moyens permettant la réalisation de la communication en champ proche (NFC), l'organe électronique 24 du dispositif de remplissage et/ou soutirage peut également comporter une radio étiquette utilisant un protocole de communication de plus longue portée, par exemple « RFID » fonctionnant dans la bande de 868 MHz, associé à la même puce ou non électronique que celle pour le champ proche.In addition to the means enabling near-field communication (NFC) to be carried out, the electronic component 24 of the filling and / or tapping device can also include a radio tag using a longer range communication protocol, for example “RFID »Operating in the 868 MHz band, associated with the same chip or not electronic as that for the near field.

Les dispositifs 10, 24 électroniques peuvent former un système de détection de la position connectée du dispositif de remplissage/soutirage sur le robinet 7 de la bouteille 6.The electronic devices 10, 24 can form a system for detecting the connected position of the filling / withdrawing device on the valve 7 of the bottle 6.

Cette détection peut être réalisée au moyen d'un contacteur électrique placé sur le corps 20, contacteur qui est actionné lorsque le corps est raccordé sur le robinet de la bouteille 6. Alternativement ou cumulativement, un contacteur peut être placé dans un organe de connexion haute pression du corps 20, et actionné par le mouvement de pièces mobiles de dispositif qui se produit lors du raccordement sur le robinet 7 de la bouteille 6 (et/ou lors d'un actionnement/déplacement d'un organe de commande d'une vanne).This detection can be carried out by means of an electrical switch placed on the body 20, a switch which is actuated when the body is connected to the valve of the bottle 6. Alternatively or cumulatively, a contactor can be placed in a high connection member. body pressure 20, and actuated by the movement of moving parts of the device which occurs during connection to the valve 7 of the bottle 6 (and / or during an actuation / movement of a control member of a valve ).

La détection du raccordement peut aussi être réalisée au moyen d'un capteur inductif ou capacitif placé sur le corps et qui est sensible à la proximité de la masse métallique du robinet 7 et/ou de la bouteille 6. De même, la détection du raccordement peut être réalisée en plaçant sur ou dans le dispositif électronique de communication du chapeau 1 une piste magnétique ou au moins un aimant (cf. réf. 17 figure 2), destiné à coopérer avec un micro-contacteur électrique situé sur le corps 20 et sensible à la présence de ces éléments magnétiques (par exemple un interrupteur « reed »). Par exemple, la piste magnétique ou l'aimant est disposé dans l'organe électronique 10 (Tag ou autre) et coopère dans ce cas avec un contacteur ou interrupteur (Switch par exemple) à commande magnétique (par exemple du type « ampoule reed ») disposée dans le bas du corps 20, notamment à proximité immédiate de l'organe électronique 24 (antenne) (cf. ci-après).Connection detection can also be achieved by means of an inductive or capacitive sensor placed on the body and which is sensitive to the proximity of the metal mass of the valve 7 and / or of the bottle 6. Likewise, the connection can be detected by placing on or in the electronic communication device of the cap 1 a magnetic strip or at least one magnet (cf. ref. 17 figure 2 ), intended to cooperate with an electric microswitch located on the body 20 and sensitive to the presence of these magnetic elements (for example a “reed” switch). For example, the magnetic track or the magnet is arranged in the electronic device 10 (Tag or other) and in this case cooperates with a contactor or switch (Switch for example) with magnetic control (for example of the “reed bulb” type. ) arranged in the lower part of the body 20, in particular in the immediate vicinity of the electronic component 24 (antenna) (see below).

L'information de présence ou d'absence de raccordement à un robinet 7 de la bouteille 6 peut être stockée dans une mémoire centrale de l'organe 24 électronique du corps 20.The information on the presence or absence of connection to a valve 7 of the bottle 6 can be stored in a central memory of the electronic organ 24 of the body 20.

Cette information permet de déclencher automatiquement ou non une tentative de lecture des informations portées par l'organe 10 électronique du chapeau 1.This information makes it possible to automatically or not automatically trigger an attempt to read the information carried by the electronic component 10 of the cap 1.

Selon une autre particularité possible, l'organe 10 électronique (antenne ou autre) peut être activé brièvement de manière périodique pour mesurer son impédance. Cette dernière serait commutée en mode de communication prolongée uniquement si l'impédance mesurée a varié suffisamment, indiquant qu'on s'approche d'un organe de communication extérieur.According to another possible particularity, the electronic device (antenna or other) can be activated briefly periodically to measure its impedance. The latter would be switched to extended communication mode only if the measured impedance has varied sufficiently, indicating that one is approaching an external communication device.

Dans l'exemple non limitatif des figures 3 et 5, le chapeau 1 comprend une seconde paroi 3 disposée concentriquement de façon espacée autour de la première paroi 1 et délimitant une zone de protection de la première paroi 2. La seconde paroi 3 comprend par exemple une portion annulaire 13 disposée concentriquement autour de la première paroi 2 et reliée à la première paroi via plusieurs bras 23 de liaison.In the non-limiting example of figures 3 and 5 , the cap 1 comprises a second wall 3 arranged concentrically in a spaced manner around the first wall 1 and delimiting a protection zone of the first wall 2. The second wall 3 comprises for example an annular portion 13 arranged concentrically around the first wall 2 and connected to the first wall via several connecting arms 23.

De préférence, selon une direction verticale s'étendant entre l'extrémité inférieure 4 du chapeau 1 et l'extrémité supérieure du chapeau, l'extrémité supérieure 12 de la première paroi 2 délimitant l'orifice 5 d'accès fait saillie au-dessus de la seconde paroi 3. C'est-à-dire que l'organe 10 électronique de communication et de stockage de données est disposé au-dessus de la seconde paroi 3 (par exemple à une distance verticale de quelques centimètres 0-10cm au-dessus de la seconde paroi 3).Preferably, in a vertical direction extending between the lower end 4 of the cap 1 and the upper end of the cap, the upper end 12 of the first wall 2 delimiting the access orifice 5 protrudes above of the second wall 3. That is to say that the electronic device 10 for communication and data storage is arranged above the second wall 3 (for example at a vertical distance of a few centimeters 0-10cm above the second wall 3).

De plus, au moins une partie de la surface périphérique de la première paroi 2 peut comporter un organe 9 d'affichage d'une information représentative de la quantité de fluide contenue dans la bouteille sur laquelle le chapeau est monté. Dans l'exemple des figures 3 et 4 cet organe 9 d'affichage comprenant un écran digital, par exemple un papier électronique (« e-paper »). Bien entendu, tout autre organe approprié peut être envisagé et notamment un manomètre. Cet organe 9 d'affichage peut être relié et commandé par l'organe 10 électronique de communication et de stockage du chapeau 1 ou celui 24 du dispositif de remplissage/soutirage et/ou par un capteur de pression dans la bouteille 6.In addition, at least part of the peripheral surface of the first wall 2 may include a member 9 for displaying information representative of the quantity of fluid contained in the bottle on which the cap is mounted. In the example of figures 3 and 4 this display member 9 comprising a digital screen, for example an electronic paper ("e-paper"). Of course, any other suitable member can be envisaged and in particular a pressure gauge. This display unit 9 can be connected and controlled by the electronic unit 10 for communication and storage of the cap 1 or that 24 of the filling / withdrawal device and / or by a pressure sensor in the bottle 6.

Cet organe 9 d'affichage peut être du type également papier électronique (« e-paper ») ou « LCD cholesterique ». Une solution possible comprendrait une série de petits afficheurs (au moins trois par exemple) comprenant par exemple une échelle de type « graphique à barres » (« bar graph »), mis en parallèle et commandés par la puce électronique.This display member 9 may also be of the electronic paper (“e-paper”) or “cholesteric LCD” type. A possible solution would include a series of small displays (at least three for example) comprising, for example, a scale of the “bar graph” type, placed in parallel and controlled by the electronic chip.
