Definitions

  • the invention relates to a gas distribution assembly comprising a gas cylinder, in particular a medical gas cylinder, a valve block, with or without an integrated expansion system fixed on the gas cylinder, a protective casing arranged around the valve block for protection against shock and dirt and a wireless information transmission system comprising a transmitting and / or receiving antenna integrated in the cowl body.
  • Gas containers typically gas cylinders with pressures greater than 100 bar absolute, generally between 200 and 350 bar abs or more, equipped with a valve block, with or without built-in expansion valve, ie a simple open / closed type faucet or an integrated pressure reducer valve, also called RDI, to control the flow and pressure of the delivered gas.
  • RDI integrated pressure reducer valve
  • Cowlings of this type are described in particular by the documents EP-A-629812 , DE-A-10057469 , US-2004/020793 and EP-A-2586481 .
  • the high-pressure gas exiting the container must therefore be expanded before it can be used, that is to say its pressure must be reduced to a lower operating pressure, called low pressure, for example a pressure less than 20 bar abs, or even often less than 10 bar abs.
  • low pressure for example a pressure less than 20 bar abs, or even often less than 10 bar abs.
  • the expansion of the gas can be done either directly in the valve block itself, when it is a built-in pressure regulator valve block, also called RDI, or downstream of the valve block by means of a pressure reducer device. gas.
  • valve block When it is desired to know the pressure of the gas (before expansion) or the residual quantity of gas in the bottle, the valve block is fitted with a device for indicating pressure or gas autonomy which is preferably of electronic nature in a manner to be able to transmit to another device, such as a computer or a remote computer server for example, and / or, conversely, to receive information transmitted by another device.
  • a device for indicating pressure or gas autonomy which is preferably of electronic nature in a manner to be able to transmit to another device, such as a computer or a remote computer server for example, and / or, conversely, to receive information transmitted by another device.
  • a transmitter / receiver system comprising an antenna adapted to and designed to transmit and / or receive information, in particular measurements of pressure or gas autonomy resulting from measurements carried out by the indicator device of pressure or autonomy in gas.
  • the congestion constraint does not allow the integration in these transmitter / receiver systems of an antenna of sufficient size to obtain a satisfactory transmission / reception quality.
  • the invention further relates to a use of a gas distribution assembly according to the invention for storing or dispensing a gas or gas mixture, preferably a gas or medical gas mixture.
  • a gas or gas mixture is chosen from oxygen, air, N 2 O / O 2 , He / O 2 or NO / nitrogen
  • a protective cover 2 commonly called “hat” arranged around a valve block 9, namely a valve with or without built-in regulator, itself attached to the neck of a gas cylinder 1, preferably the valve block is of type RDI.
  • the lower part, also called the lower part, of the cowling 2 is located at the level of the bottle 1.
  • the fixing around the valve block on the neck of the gas cylinder 1 is done by screwing either directly on the tap itself via a complementary and / or adapted geometry.
  • the gas cylinder 1 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).
  • the protective cover 2 protects the valve block 9 against shocks. To do this, it comprises a cowling body 10 forming a protective shell around an internal volume sized to receive the valve block 9.

Description

L'invention porte sur un ensemble de distribution de gaz comprenant une bouteille de gaz, en particulier de gaz médical, un bloc robinet, avec ou sans système de détente intégré fixé sur la bouteille de gaz, un capotage de protection agencé autour du bloc robinet pour le protéger des chocs et des salissures et un système de transmission d'informations sans fil comprenant une antenne émettrice et/ou réceptrice intégrée au corps de capotage.The invention relates to a gas distribution assembly comprising a gas cylinder, in particular a medical gas cylinder, a valve block, with or without an integrated expansion system fixed on the gas cylinder, a protective casing arranged around the valve block for protection against shock and dirt and a wireless information transmission system comprising a transmitting and / or receiving antenna integrated in the cowl body.

Les gaz industriels et médicaux sont couramment conditionnés à haute pression dans des récipients de gaz, typiquement des bouteilles de gaz supportant des pressions supérieures à 100 bar absolus, en général entre 200 et 350 bar abs ou plus, équipés d'un bloc robinet, avec ou sans détendeur intégré, à savoir un robinet simple de type ouvert/fermé ou un robinet à détendeur intégré, encore appelé RDI, permettant de contrôler débit et pression du gaz délivré.Industrial and medical gases are commonly packaged at high pressure in gas containers, typically gas cylinders with pressures greater than 100 bar absolute, generally between 200 and 350 bar abs or more, equipped with a valve block, with or without built-in expansion valve, ie a simple open / closed type faucet or an integrated pressure reducer valve, also called RDI, to control the flow and pressure of the delivered gas.

Il est courant d'agencer autour dudit bloc robinet, un capotage de protection formant coque protectrice autour du corps du robinet. Un tel capotage est couramment appelé « chapeau ». Des capotages de ce type sont décrits notamment par les documents EP-A-629812 , DE-A-10057469 , US-A-2004/020793 et EP-A-2586481 .It is common to arrange around said valve block, a protective cover forming a protective shell around the valve body. Such a cowling is commonly called "hat". Cowlings of this type are described in particular by the documents EP-A-629812 , DE-A-10057469 , US-2004/020793 and EP-A-2586481 .

Le gaz à haute pression sortant du récipient doit donc être détendu avant de pouvoir être utilisé, c'est-à-dire que sa pression doit être réduite jusqu'à une pression d'utilisation plus basse, appelée basse pression, par exemple une pression inférieure à 20 bar abs, voire même souvent inférieure à 10 bar abs. La détente du gaz peut se faire soit directement dans le bloc robinet lui-même, lorsqu'il s'agit d'un bloc robinet à détendeur intégré, encore appelé RDI, soit en aval du bloc robinet au moyen d'un dispositif détendeur de gaz.The high-pressure gas exiting the container must therefore be expanded before it can be used, that is to say its pressure must be reduced to a lower operating pressure, called low pressure, for example a pressure less than 20 bar abs, or even often less than 10 bar abs. The expansion of the gas can be done either directly in the valve block itself, when it is a built-in pressure regulator valve block, also called RDI, or downstream of the valve block by means of a pressure reducer device. gas.

Lorsque l'on souhaite connaître la pression du gaz (avant détente) ou la quantité résiduelle de gaz dans la bouteille, on équipe le bloc robinet d'un dispositif indicateur de pression ou d'autonomie en gaz qui est préférentiellement de nature électronique de manière à pouvoir émettre vers un autre appareil, tel un ordinateur ou un serveur informatique distant par exemple, et/ou, à l'inverse, recevoir des informations transmises par un autre appareil.When it is desired to know the pressure of the gas (before expansion) or the residual quantity of gas in the bottle, the valve block is fitted with a device for indicating pressure or gas autonomy which is preferably of electronic nature in a manner to be able to transmit to another device, such as a computer or a remote computer server for example, and / or, conversely, to receive information transmitted by another device.

Ceci se fait généralement au moyen d'un système émetteur/récepteur comprenant une antenne apte à et conçue pour émettre et/ou recevoir des informations, en particulier des mesures de pressions ou d'autonomie en gaz provenant de mesures opérées par le dispositif indicateur de pression ou d'autonomie en gaz.This is generally done by means of a transmitter / receiver system comprising an antenna adapted to and designed to transmit and / or receive information, in particular measurements of pressure or gas autonomy resulting from measurements carried out by the indicator device of pressure or autonomy in gas.

Or, il a été constaté en pratique que la contrainte d'encombrement ne permet pas l'intégration dans ces systèmes émetteurs/récepteurs, d'une antenne de taille suffisante pour obtenir une qualité d'émission/réception satisfaisante.However, it has been found in practice that the congestion constraint does not allow the integration in these transmitter / receiver systems of an antenna of sufficient size to obtain a satisfactory transmission / reception quality.

En d'autres termes, avec les dispositifs existants et les ensembles bouteille/bloc robinet/capotage existants, il se pose des problèmes de fiabilité de transmission d'information, c'est-à-dire d'émission ou de réception, du fait de la limitation de la taille de l'antenne du système émetteur/récepteur.In other words, with the existing devices and the existing cylinder / tap / cowl assemblies, there are problems of reliability of transmission of information, that is to say of emission or reception, because of limitation of the antenna size of the transmitter / receiver system.

La solution de l'invention est alors un ensemble de distribution de gaz comprenant :

  • un récipient de gaz équipé d'un bloc robinet comprenant un passage interne de gaz,
  • un capotage de protection comprenant un corps de capotage entourant tout ou partie dudit bloc robinet,
  • au moins un capteur de pression agencé de manière à mesurer la pression de gaz au sein dudit passage interne de gaz du bloc robinet,
  • des moyens de traitement d'informations reliés audit au moins un capteur de pression,
  • un système de transmission d'informations sans fil comprenant une antenne émettrice et/ou réceptrice, et
  • au moins une source d'énergie électrique alimentant électriquement ledit au moins un capteur de pression, lesdits moyens de traitement d'informations et ledit système de transmission d'informations,
caractérisé en ce que ladite antenne émettrice et/ou réceptrice est intégrée audit corps de capotage.The solution of the invention is then a gas distribution assembly comprising:
  • a gas container equipped with a valve block comprising an internal gas passage,
  • a protective cowling comprising a cowling body surrounding all or part of said valve block,
  • at least one pressure sensor arranged to measure the gas pressure within said internal gas passage of the valve block,
  • information processing means connected to said at least one pressure sensor,
  • a wireless information transmission system comprising a transmitting and / or receiving antenna, and
  • at least one source of electrical energy electrically supplying said at least one pressure sensor, said information processing means and said information transmission system,
characterized in that said transmitting and / or receiving antenna is integrated with said casing body.

Conformément à la présente invention, intégrer l'antenne au corps du capotage est avantageux car cela permet de :

  • utiliser une antenne de plus grandes dimensions, donc d'améliorer les émissions et réceptions, c'est-à-dire la fiabilité de transmission d'informations,
  • protéger l'antenne contre les chocs et les détériorations puisqu'aucune antenne ne dépasse du capotage,
  • ne pas augmenter l'encombrement général de l'ensemble.
According to the present invention, integrating the antenna to the casing body is advantageous because it allows:

L'invention va maintenant être mieux comprise grâce à la description détaillée suivante, faite à titre illustratif mais non limitatif, en référence aux figures annexées parmi lesquelles :

  • la Figure 1 est un schéma de principe d'un ensemble bouteille/bloc robinet/capotage selon l'invention,
  • la Figure 2 représente un mode de réalisation d'un ensemble bouteille/bloc robinet/capotage selon l'invention,
  • la Figure 3 illustre l'architecture des moyens de traitement d'informations et du système de transmission d'informations sans fil, et
  • la Figure 4 schématise le principe de la chaine de traitement et d'envoi des informations ou données à un appareil distant.
The invention will now be better understood thanks to the following detailed description, given by way of illustration but without limitation, with reference to the appended figures among which:
  • the Figure 1 is a block diagram of a cylinder / valve block / cowl assembly according to the invention,
  • the Figure 2 represents an embodiment of a cylinder / valve block / cowl assembly according to the invention,
  • the Figure 3 illustrates the architecture of the information processing means and the wireless information transmission system, and
  • the Figure 4 schematizes the principle of the chain of processing and sending information or data to a remote device.

Plus précisément, on voit sur les Figures annexées, un capotage de protection 2, couramment appelé « chapeau », agencé autour d'un bloc robinet 9, à savoir un robinet avec ou sans détendeur intégré, lui-même fixé sur le col d'une bouteille de gaz 1, de préférence le bloc robinet est de type RDI.More specifically, we see in the accompanying Figures, a protective cover 2, commonly called "hat", arranged around a valve block 9, namely a valve with or without built-in regulator, itself attached to the neck of a gas cylinder 1, preferably the valve block is of type RDI.

La partie inférieure, encore appelée partie basse, du capotage 2 est située au niveau de la bouteille 1. La fixation autour du bloc de robinet sur le col de la bouteille de gaz 1 se fait par vissage soit directement sur le robinet lui-même via une géométrie complémentaire et/ou adaptée.The lower part, also called the lower part, of the cowling 2 is located at the level of the bottle 1. The fixing around the valve block on the neck of the gas cylinder 1 is done by screwing either directly on the tap itself via a complementary and / or adapted geometry.

La bouteille de gaz 1 a typiquement un corps cylindrique en acier et une taille entre 10 et 150 cm, et une contenance de 0,5 à 20 litres (en équivalent eau).The gas cylinder 1 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).

Le capotage de protection 2 permet de protéger le bloc robinet 9 contre les chocs. Pour ce faire, il comprend un corps de capotage 10 formant une coque protectrice autour d'un volume interne dimensionné pour recevoir le bloc robinet 9.The protective cover 2 protects the valve block 9 against shocks. To do this, it comprises a cowling body 10 forming a protective shell around an internal volume sized to receive the valve block 9.

Le capotage 2 comprend par ailleurs une poignée de portage 7 conçue pour être prise en main par un utilisateur. La poignée de portage 7 est formée d'un matériau rigide, tel un polymère ou un métal ou alliage métallique, et est solidaire du corps 10 de capotage. Elle est préférentiellement agencée horizontalement, c'est-à-dire perpendiculairement ou quasi-perpendiculairement par rapport à l'axe vertical de la bouteille 1 et du capotage 2. La poignée de portage 7 a une forme longiligne, qu'elle soit rectiligne ou incurvée, typiquement une longueur inférieure à 20 cm, typiquement de 6 à 15 cm.The cowling 2 further comprises a carrying handle 7 designed to be handled by a user. The carrying handle 7 is formed of a rigid material, such as a polymer or a metal or metal alloy, and is integral with the body 10 cowl. It is preferably arranged horizontally, that is to say perpendicularly or almost perpendicular to the vertical axis of the bottle 1 and the cowling 2. The handle of port 7 has an elongated shape, whether rectilinear or curved, typically a length less than 20 cm, typically 6 to 15 cm.

Dans tous les cas, le corps du capotage 2 est typiquement en un matériau de type polymère et/ou métal, préférentiellement en matériau plastique, tel que PVC, PE, PET, PP, PMMA, PU, PA...In all cases, the casing body 2 is typically made of a polymer and / or metal type material, preferably made of plastic material, such as PVC, PE, PET, PP, PMMA, PU, PA ...

Par ailleurs, le corps de robinet du bloc robinet 9 comprend classiquement un système de fixation, par exemple une portion filetée conique, tronconique ou cylindrique, permettant de fixer le bloc robinet 9 au récipient de gaz 1, par exemple par vissage. Cette portion filetée comprend un orifice d'entrée de gaz par lequel le gaz contenu dans le récipient 1 peut pénétrer dans le corps de robinet 9.Furthermore, the valve body of the valve block 9 conventionally comprises a fastening system, for example a conical, frustoconical or cylindrical threaded portion, for fixing the valve block 9 to the gas container 1, for example by screwing. This threaded portion comprises a gas inlet orifice through which the gas contained in the container 1 can penetrate into the valve body 9.

Le bloc robinet comprend par ailleurs un orifice de sortie de gaz porté par un raccord de sortie de gaz par lequel le gaz peut ressortir du corps de robinet 9. Un passage interne de gaz relie fluidiquement l'orifice d'entrée de gaz à l'orifice de sortie de gaz.The valve block further comprises a gas outlet port carried by a gas outlet connection through which the gas can emerge from the valve body 9. An internal gas passage fluidly connects the gas inlet port to the gas outlet port.

Un capteur de pression fixé au corps de robinet permet de mesurer la pression du gaz dans le passage interne de gaz, de préférence en amont du site où le gaz est détendu, lorsque le bloc robinet 9 est de type RDI et intègre donc un système de réduction de pression, par exemple un clapet de détente coopérant avec un siège de clapet. Ce capteur permet de déterminer la pression du gaz, ladite pression étant ensuite utilisée par des moyens de traitement d'informations pour en déduire éventuellement une autonomie en gaz de la bouteille 1.A pressure sensor attached to the valve body makes it possible to measure the pressure of the gas in the internal gas passage, preferably upstream of the site where the gas is expanded, when the valve block 9 is of the RDI type and therefore integrates a system of pressure reduction, for example a relief valve cooperating with a valve seat. This sensor makes it possible to determine the pressure of the gas, said pressure being then used by information processing means to possibly deduce a gas autonomy of the bottle 1.

De façon classique, un organe 8 de commande du débit de gaz, tel ici un volant rotatif, permet à l'utilisateur de contrôler le débit du gaz traversant le bloc robinet 9. Cet organe 8 de commande du débit de gaz coopère avec un système de contrôle de passage de gaz agencé sur le passage interne de gaz, c'est-à-dire dans le bloc robinet 9.In a conventional manner, a gas flow control member 8, such as a rotary handwheel, allows the user to control the flow rate of the gas passing through the valve block 9. This gas flow control member 8 cooperates with a system gas flow control device arranged on the internal gas passage, that is to say in the valve block 9.

Afin de permettre l'accroche ou l'arrimage de l'ensemble bouteille/bloc robinet/capotage à un support, tel un barreau de lit d'hôpital ou de brancard, le capotage de protection 2 peut comprendre, du côté de sa face arrière, un dispositif d'accrochage fixe ou mobile, par exemple translatif ou pivotant entre une position dite « de repos », c'est-à-dire la position adoptée par le dispositif d'accrochage lorsqu'il est rangé et en contact ou quasi-contact du corps du capotage 2, et une position dite « d'accrochage », c'est-à-dire la position adoptée par le dispositif d'accrochage lorsqu'il est complètement sorti et peut être accroché à un support, tel un barreau de lit ou analogue.In order to allow the hooking or stowage of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective cover 2 may comprise, on the side of its rear face a fixed or movable attachment device, for example translatable or pivoting between a so-called "rest" position, that is to say the position adopted by the attachment device when it is stored and in contact or almost -contact the body of the cowling 2, and a so-called "hooking" position, that is to say the position adopted by the hooking device when it is completely out and can be hooked to a support, such a bed rail or the like.

De façon générale, les mesures opérées par le capteur de pression 15 sont traitées, comme expliqué ci-après, par des moyens de traitement d'informations 11, 12, par exemple au moins un microprocesseur 12 associé à un ou plusieurs algorithmes, puis éventuellement stockées au sein d'une mémoire de stockage d'informations.In general, the measurements made by the pressure sensor 15 are processed, as explained hereinafter, by information processing means 11, 12, for example at least one microprocessor 12 associated with one or more algorithms, and then possibly stored in an information storage memory.

Une source électrique, par exemple une ou plusieurs batteries ou piles électriques, rechargeable ou non, alimente en courant électrique les moyens de traitement d'informations 11, 12 et le système de transmission d'informations 3. La source d'énergie électrique est fixée au corps de robinet 9 ou dans un logement aménagé dans la paroi du corps 10 de capotage 2, par exemple un compartiment dédié.An electrical source, for example one or more rechargeable batteries or electric batteries, supplies electric power to the information processing means 11, 12 and the information transmission system 3. The source of electrical energy is fixed to the valve body 9 or in a housing provided in the wall of the body 10 of the cowling 2, for example a dedicated compartment.

La Figure 2 illustre une architecture possible des moyens de traitement d'informations et du système de transmission d'informations sans fil.The Figure 2 illustrates a possible architecture of the information processing means and the wireless information transmission system.

D'une manière générale, une carte électronique 11 principale embarque un module de calcul comprenant un microprocesseur 12, et un module de communication 13 qui comprend un moyen de traitement de l'information apte à émettre/recevoir des informations, tel un module RF, un modem GSM, un module Wifi, un module Bluetooth ou autre, et une antenne 5 reliée électriquement, via une liaison électrique et/ou un connecteur dédié 16, à la carte électronique 11 principale portant le module de communication 13 du système de transmission d'informations 3.In general, a main electronic card 11 embeds a calculation module comprising a microprocessor 12, and a communication module 13 which comprises an information processing means capable of transmitting / receiving information, such as an RF module, a GSM modem, a WiFi module, a Bluetooth module or the like, and an antenna 5 electrically connected, via an electrical connection and / or a dedicated connector 16, to the main electronic card 11 carrying the communication module 13 of the transmission system. information 3.

Dans le mode de réalisation présenté sur la Figure 2, les moyens de traitement d'informations 11, 12 et le système de transmission d'informations 3 sont portés par une même carte électronique 11 principale. Toutefois, le module de communication formant tout ou partie du système de transmission d'informations 3 pourrait aussi être ou comprendre ou être porté par une carte électronique supplémentaire reliée à la carte électronique 11 principale.In the embodiment presented on the Figure 2 , the information processing means 11, 12 and the information transmission system 3 are carried by one and the same main electronic card 11. However, the communication module forming all or part of the information transmission system 3 could also be or understand or be carried by an additional electronic card connected to the main electronic card 11.

Les moyens de traitement d'informations 11, 12 comprennent donc une carte électronique 11 comprenant un organe calculateur 12, tel un microprocesseur, ladite carte électronique 11 étant fixée sur le robinet ou dans un logement aménagé dans la paroi du capotage 2, et reliée électriquement au capteur de pression fixé sur le corps de robinet 9, via une liaison électrique et/ou un connecteur dédié 14.The information processing means 11, 12 thus comprise an electronic card 11 comprising a calculator member 12, such as a microprocessor, said electronic card 11 being fixed on the tap or in a housing provided in the wall of the casing 2, and electrically connected. the pressure sensor fixed on the valve body 9, via an electrical connection and / or a dedicated connector 14.

L'alimentation électrique du capteur 15 se fait donc via la carte électronique 11.The power supply of the sensor 15 is therefore via the electronic card 11.

Les moyens de traitement d'informations 11, 12 sont en outre reliés au système de transmission d'informations sans fil 3 comprenant l'antenne émettrice et/ou réceptrice 5 agencée dans le corps 10 du capotage 2, de manière à pouvoir transmettre des informations, notamment de pression et/ou d'autonomie en gaz, à un appareil distant, via l'antenne 5.The information processing means 11, 12 are furthermore connected to the wireless information transmission system 3 comprising the transmitting and / or receiving antenna 5 arranged in the body 10 of the cowling 2, so as to be able to transmit information , in particular pressure and / or gas autonomy, to a remote device via the antenna 5.

En d'autres termes, le système de transmission d'informations 3 sans fil est apte à et conçu pour émettre et/ou recevoir des informations, i.e., toute type de donnée ou d'ordre. L'émission d'informations se fait vers un appareil distant, alors qu'à l'inverse, la réception par le système de transmission d'informations 3 comprend la récupération d'informations provenant d'un appareil distant.In other words, the wireless information transmission system 3 is adapted to and designed to transmit and / or receive information, i.e., any type of data or order. The transmission of information is to a remote device, while conversely, the reception by the information transmission system 3 includes the retrieval of information from a remote device.

L'appareil distant peut être un ordinateur, un serveur informatique, un téléphone intelligent, une tablette tactile.... ou tout autre appareil dédié ou non.The remote device can be a computer, a computer server, a smartphone, a touch pad .... or any other dedicated device or not.

De façon générale la transmission d'informations se fait via l'antenne 5 émettrice et/ou réceptrice qui est reliée par au moins un fil électrique 4 ou analogue au système de transmission d'informations 3.In general, the transmission of information is via the transmitting and / or receiving antenna 5 which is connected by at least one electrical wire 4 or the like to the information transmission system 3.

L'antenne 5 est choisie de manière à pouvoir rayonner, c'est-à-dire émettre, et/ou capter, c'est-à-dire recevoir, des informations sous forme d'ondes électromagnétiques, donc capable d'effectuer une conversion dans un sens ou dans l'autre entre une puissance électrique et une puissance électromagnétique.The antenna 5 is chosen so as to be able to radiate, that is to say emit, and / or pick up, that is to say receive, information in the form of electromagnetic waves, thus capable of performing a conversion in one direction or the other between electrical power and electromagnetic power.

La Figure 4 illustre le principe de la chaîne de traitement des informations recueillies par le capteur 15 et ensuite émises via l'antenne 5.The Figure 4 illustrates the principle of the processing chain of the information collected by the sensor 15 and then transmitted via the antenna 5.

A titre illustratif mais non limitatif, on prendra ci-après l'exemple d'une donnée de pression mesurée par le capteur 15 dans le passage interne du robinet 9 équipant la bouteille 1.By way of illustration but without limitation, the following will be taken as an example of a pressure data measured by the sensor 15 in the internal passage of the valve 9 fitted to the bottle 1.

Dans ce cas, la chaîne de traitement des informations comprend schématiquement les étapes suivantes :

  • Etape A : Acquisition d'une (ou plusieurs) donnée(s) par le capteur 15 fixé au robinet, à savoir ici une donnée de pression.
  • Etape B : Traitement (i.e. calculs) de la donnée par le module calculateur 12 à microprocesseur au sein des moyens de traitement d'informations 11, 12 et mise en forme de la donnée ou du résultat des calculs pour une transmission subséquente de celle-ci par le module de communication 13.
  • Etape C : transmission sans fil de la (ou des) donnée par le module de communication 13 du système de transmission d'informations 3, via l'antenne 5 située dans le montant-support 4 de la poignée 3.
  • Etape D : Réception de ou des données par un appareil distant 20, par exemple un ordinateur, un serveur informatique, un téléphone intelligent, une tablette tactile ou autre. Cet appareil distant 20 peut alors les afficher, les mémoriser, les traiter, les éditer, les utiliser....
In this case, the information processing chain schematically comprises the following steps:
  • Step A: Acquisition of one (or more) data (s) by the sensor 15 attached to the valve, namely here a pressure data.
  • Step B: Processing (ie calculations) of the data by the microprocessor calculator module 12 within the information processing means 11, 12 and formatting of the data or the result of the calculations for a subsequent transmission thereof by the communication module 13.
  • Step C: wireless transmission of the (or) data by the communication module 13 of the information transmission system 3, via the antenna 5 located in the support-upright 4 of the handle 3.
  • Step D: Receiving data from a remote device 20, for example a computer, a computer server, a smartphone, a touch pad or the like. This remote device 20 can then display them, memorize them, process them, edit them, use them.

Les étapes A à C sont mises en oeuvre par l'ensemble de distribution de gaz selon l'invention, c'est-à-dire sont opérées au niveau de la bouteille 1.Steps A to C are implemented by the gas distribution assembly according to the invention, that is to say are operated at the level of the bottle 1.
