Description

Dispositif de mesure fiabilisée de la quantité de fluide circulant dans une canalisation et système fiabilisé de réception de données équipé de tel dispositifReliable measurement device for the quantity of fluid circulating in a pipeline and reliable data reception system equipped with such a device
La présente invention se rapporte au domaine de la mesure fiabilisee de quantité de fluide circulant dans des canalisationsThe present invention relates to the field of reliable measurement of the quantity of fluid flowing in pipes.
La présente invention se rapporte plus particulièrement à un dispositif de mesure fiabilisée de la quantité de fluide circulant dans au moins une canalisation, du type comportant au moins un capteur de débit muni d'au moins un fil de transmission d'information charge de transmettre l'information issue du capteur de débit vers une centrale de gestion de I informationThe present invention relates more particularly to a reliable measurement device for the quantity of fluid circulating in at least one pipe, of the type comprising at least one flow sensor provided with at least one information transmission wire responsible for transmitting the information from the flow sensor to an information management center
Une centrale de gestion de I information permet d'une manière générale de visualiser les différents paramètres concernant le débit de fluide à l'intérieur de la canalisation, et permet par exemple, de visualiser les différents paramètres concernant la consommation en eau froide et / ou en eau chaude dans un logement Cette centrale peut également permettre de déceler une fuite dans la canalisationA central information management unit generally allows the display of the various parameters relating to the fluid flow rate inside the pipe, and allows, for example, the display of the various parameters concerning the consumption of cold water and / or in hot water in a dwelling This unit can also make it possible to detect a leak in the pipe
L'art antérieur connaît plusieurs procèdes et dispositifs qui tentent de récolter des informations envoyées par un ou plusieurs capteurs de débit positionnés sur des canalisations afin de permettre une visualisation plus aisée des informations relatives au débit dans ces canalisationsThe prior art knows several methods and devices which attempt to collect information sent by one or more flow sensors positioned on pipes in order to allow easier viewing of information relating to the flow in these pipes.
L art antérieur connaît notamment la demande de brevet européen N° 661 526 qui porte sur un procède et un dispositif pour la collection d'informations en provenance d'un compteur d eauThe prior art notably knows European patent application N ° 661 526 which relates to a method and a device for the collection of information coming from a water meter.
Selon ce document, les informations collectées par le compteur électronique sont converties en pulsations logiques et sont transformées en ondes mécaniques par un émetteur situé sur la canalisation, le plus proche possible du compteur d eau Ces informations sont ensuite transmises à un receveur local ou a un receveur régional grâce à un récepteur d ondesAccording to this document, the information collected by the electronic meter is converted into logical pulses and is transformed into mechanical waves by a transmitter located on the pipe, as close as possible to the water meter. This information is then transmitted to a local receiver or to a regional receiver thanks to a wave receiver
Tous les dispositifs de l'art antérieur utilisent des capteurs à impulsion et sont, par conséquent, confrontes a un problème important le traitement des informations issues du capteur doit être opéré à proximité du capteur car dans une ambiance normale, le fil d'émission du capteur se charge rapidement de parasites qu'il est impossible de distinguer des impulsions envoyées par le capteurAll the devices of the prior art use pulse sensors and are therefore faced with an important problem the processing of information from the sensor must be operated near the sensor because in a normal environment, the transmission wire of the sensor quickly loads parasites that cannot be distinguished from the pulses sent by the sensor
Or dans la pratique pour que les informations fournies par le capteur puissent être utilisées d'une manière fiable par la société qui gère la distribution de l'eau, le capteur doit être positionné à la limite entre la canalisation qui est la propriété de la compagnie de distribution de l'eau et la canalisation qui est la propriété de l'usager, c'est à dire là où est positionné le compteur volumétπque traditionnelHowever in practice so that the information provided by the sensor can be used in a reliable manner by the company which manages the water distribution, the sensor must be positioned at the limit between the pipe which is the property of the water distribution company and the pipeline which is the property of the user, i.e. where the traditional volumetric meter is positioned
Il est évident que dans la majorité des cas la centrale de traitement de 5 l'information ne peut pas être disposée auprès du capteur car l'environnement autour du capteur, souvent très humide, est fortement défavorable à son bon fonctionnementIt is obvious that in the majority of cases the information processing center cannot be placed near the sensor because the environment around the sensor, often very humid, is strongly unfavorable for its proper functioning.
La présente invention entend remédier aux inconvénients de l'art antérieur en proposant un dispositif qui permette une transmission fiable des informations ιo fournies par un capteur de débit et en particulier, par un capteur de débit situé par exemple sur une canalisation d'eau courante, froide ou chaudeThe present invention intends to remedy the drawbacks of the prior art by proposing a device which allows reliable transmission of the information supplied by a flow sensor and in particular by a flow sensor located for example on a running water pipe, cold or hot
Le dispositif selon l'invention est remarquable en ce que préalablement à la transmission de l'information vers la centrale de gestion de I information, c'est à dire des que l'information est réalisée par le capteur de débit l'information est traitée par ι > au moins un microcontrôleur d'échantillonnageThe device according to the invention is remarkable in that, prior to the transmission of the information to the information management center, that is to say as soon as the information is produced by the flow sensor, the information is processed by ι> at least one sampling microcontroller
Le but de cette étape est de permettre la transmission de l'information, non pas sous forme d'impulsion ou de bit, mais sous forme de mot ou digitThe goal of this step is to allow the transmission of information, not in the form of pulse or bit, but in the form of word or digit
Ainsi, si un parasite apparaît dans l'information, le mot en est complètement bouleversé et il est très facile de détecter son incohérence au niveau de la centrale 0 de gestion de l'information II suffit alors d'attendre que la centrale de gestion deThus, if a parasite appears in the information, the word is completely turned upside down and it is very easy to detect its inconsistency at the level of the information management center 0 It is then sufficient to wait until the data management center
I information reçoive des informations cohérentes pour mettre à jour les données gérées par elle et les paramètres concernant la consommationI information receives consistent information to update the data managed by it and the parameters concerning consumption
De plus, la transmission de l'information émise par ledit capteur de débit n est opérée qu'après que ladite centrale de gestion de l'information l'ait demandé - auprès du microcontrôleur d'échantillonnageIn addition, the transmission of the information transmitted by said flow sensor is only carried out after said central information management has requested it - to the sampling microcontroller
Ainsi, il est possible d'économiser un certain nombre de transferts d'information et par voie de conséquence, une quantité non négligeable d'énergie, en n'opérant le transfert de l'information que lorsque cela est nécessaireThus, it is possible to save a certain number of transfers of information and consequently, a non-negligible amount of energy, by operating the transfer of information only when it is necessary
De plus, le dispositif selon l'invention est remarquable en ce qu'il comporte 0 en outre, entre la sortie du capteur de débit et ledit fil de transmission d'information, au moins un microcontrôleur d'échantillonnage et en ce que ledit capteur de débit et ledit microcontrôleur d'échantillonnage sont venus de matièreIn addition, the device according to the invention is remarkable in that it further comprises 0, between the output of the flow sensor and said information transmission wire, at least one sampling microcontroller and in that said sensor flow rate and said sampling microcontroller came from material
Ainsi, les impulsions envoyées par le capteur sont directement traitées par le microcontrôleur d'échantillonnage avant d'être transférées vers la centrale de 5 gestion de l'information En outre, le dispositif selon l'invention est remarquable en ce qu'il permet de déterminer le sens de circulation du fluide dans ladite canalisation et ainsi de soustraire le débit de retour de fluide qui s'opère dans le sens inverse du débit de consommation En outre, également, grâce au dispositif selon l'invention, le transfert de l'information peut être opéré par les fils d'alimentation du capteur de débit ce qui simplifie bien évidemment le montageThus, the pulses sent by the sensor are directly processed by the sampling microcontroller before being transferred to the information management center. In addition, the device according to the invention is remarkable in that it makes it possible to determine the direction of circulation of the fluid in said pipe and thus to subtract the return flow of fluid which takes place in the opposite direction from the consumption flow. In addition, also, thanks to the device according to the invention, the transfer of information can be carried out by the feed wires of the flow sensor, which obviously simplifies mounting.
En outre, enfin, ledit fil de transmission d'information peut être chargé de transmettre les informations issues d'au moins un autre dispositif de mesure fiabilisée selon l'invention positionnés soit en d'autres endroits sur la même canalisation, soit sur d'autres canalisationsIn addition, finally, said information transmission wire can be responsible for transmitting information from at least one other reliable measurement device according to the invention positioned either in other places on the same pipe, or on other pipes
En effet, la présente invention permet de réaliser un système complexe et important de réception et de traitement de données comportant une multitude de dispositifs selon l'invention Un autre objet de la présente invention concerne un système fiabilisé de réception de données concernant la consommation en fluide dans une pluralité de logements, caractérisé en ce qu'il comporte au moins deux dispositifs conformes à l'une quelconque des caractéristiques mentionnées ci-dessusIn fact, the present invention makes it possible to produce a complex and important system for receiving and processing data comprising a multitude of devices according to the invention. Another object of the present invention relates to a reliable system for receiving data concerning the consumption of fluid. in a plurality of housings, characterized in that it comprises at least two devices conforming to any of the characteristics mentioned above
Selon une caractéristique avantageuse, les dispositifs de mesure sont disposés sur des canalisations d'eau froide et / ou d'eau chaudeAccording to an advantageous characteristic, the measuring devices are arranged on cold water and / or hot water pipes.
Selon encore une caractéristique avantageuse, chaque centrale de gestion de l'information reçoit des informations de un ou de plusieurs dispositifs de mesure et des concentrateurs réceptionnent des informations en provenance de plusieurs centrales de gestion de I information et les informations stockées dans les concentrateurs sont régulièrement expédiées a un ou plusieurs ordinateurs, par l'intermédiaire de câbles téléphoniqueAccording to another advantageous characteristic, each information management center receives information from one or more measuring devices and concentrators receive information from several information management centers and the information stored in the concentrators is regularly shipped to one or more computers, via telephone cables
On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode de mise en oeuvre donné à titre d'exemple non limitatif, en référence aux figures annexées dans lesquelles - la figure' 1 illustre le procédé et le dispositif de mesure fiabihsee selon l'invention , les figures 2 et 3 illustrent respectivement une vue de face et une vue arrière d'un capteur de débit à double relais comportant quatre aimants , la figure 4 illustre l'angle entre deux relais positionnés croisés , - les figures 5 et 6 illustrent respectivement une vue de face et une vue de profil d'un capteur de débit à double relais , et la figure 7 illustre une vue d'ensemble du procédé et du dispositif de mesure fiabilisée selon l'inventionThe invention will be better understood with the aid of the description given below of an embodiment given by way of nonlimiting example, with reference to the appended figures in which - Figure ' 1 illustrates the process and the fiabihsee measuring device according to the invention, FIGS. 2 and 3 respectively illustrate a front view and a rear view of a flow sensor with double relay comprising four magnets, FIG. 4 illustrates the angle between two relays positioned crossed , - Figures 5 and 6 respectively illustrate a front view and a side view of a dual relay flow sensor, and FIG. 7 illustrates an overall view of the reliable measurement method and device according to the invention
Le procédé, illustré figure 1 , est un procédé de mesure fiabilisée de la quantité de fluide circulant dans au moins une canalisation (1 ), du type comportant une étape de mesure du débit à l'intérieur de ladite canalisation (1 ) à l'aide d'au moins un capteur de débit (2) et une étape de transmission de I information émise par ledit capteur de débit (2) vers au moins une centrale de gestion de l'information (3), comportant, notamment, un microcontrôleur de gestionThe method, illustrated in FIG. 1, is a reliable measurement method of the quantity of fluid circulating in at least one pipe (1), of the type comprising a step of measuring the flow rate inside said pipe (1) at the using at least one flow sensor (2) and a step of transmitting the information transmitted by said flow sensor (2) to at least one information management center (3), comprising, in particular, a microcontroller Management
Chaque centrale de gestion de l'information (3) permet par exemple, à l'utilisateur de visualiser les données concernant la ou les consommations dans la ou les canalisations ( 1 ), grâce à un écran et à une pluralité de menusEach information management center (3) allows, for example, the user to view the data relating to the consumption (s) in the pipe (s) (1), thanks to a screen and to a plurality of menus.
Le procède est caractérise en ce que préalablement a la transmission l'information est traitée par au moins un microcontrôleur d'échantillonnage (4), afin de procéder à la transmission de I information émise par le capteur de débit (2), non pas sous forme d'impulsions ou de bits, mais sous forme de mots ou digitsThe method is characterized in that, prior to transmission, the information is processed by at least one sampling microcontroller (4), in order to transmit the information transmitted by the flow sensor (2), not under in the form of pulses or bits, but in the form of words or digits
En effet il est beaucoup plus facile, pour la centrale de gestion de l'information (3) grâce à un logiciel adapté, de détecter une incohérence due par exemple à un ou plusieurs parasites, dans une information transmise sous forme de mots Le procédé est en outre caractérisé en ce que la transmission de l'information émise par ledit capteur de débit (2) n'est opérée qu'après que ladite centrale de gestion de l'information (3) l'ait demandé auprès du microcontrôleur d'échantillonnage (4)Indeed, it is much easier, for the information management center (3) thanks to a suitable software, to detect an inconsistency due for example to one or more parasites, in an information transmitted in the form of words The process is further characterized in that the transmission of the information transmitted by said flow sensor (2) is only carried out after said information management center (3) has requested it from the sampling microcontroller (4)
La centrale de gestion de I information (3) peut ainsi demander les informations au microcontrôleur d'échantillonnage (4) en utilisant un système d'adressage et peut récupérer la réponse immédiatement après, afin de procéder aux comptages et à la gestion programmésThe information management center (3) can thus request the information from the sampling microcontroller (4) using an addressing system and can retrieve the response immediately afterwards, in order to carry out the scheduled counts and management.
Ainsi la centrale de gestion de l'information (3) peut aussi demander des informations a plusieurs microcontrôleurs d'échantillonnage (4) en utilisant des systèmes d'adressage spécifiques à chaque microcontrôleur d'échantillonnage (4)Thus the information management center (3) can also request information from several sampling microcontrollers (4) by using addressing systems specific to each sampling microcontroller (4).
La présente invention se rapporte également à un dispositif (5) de mesure fiabilisée de la quantité de fluide circulant dans au moins une canalisation (1 ), permettant la mise en oeuvre du procédé selon l'invention, illustré figure 1 , du type comportant au moins un capteur de débit (2) et au moins un fil de transmission d'information (6) chargé de transmettre l'information issue du capteur de débit (2) vers une centrale de gestion de l'information (3) Le dispositif (5) est caractérisé en ce qu'il comporte en outre, entre la sortie du capteur de débit (2) et ledit fil de transmission d'information (6), au moins un microcontrôleur d'échantillonnage (4)The present invention also relates to a device (5) for reliable measurement of the quantity of fluid circulating in at least one pipe (1), allowing the implementation of the method according to the invention, illustrated in FIG. 1, of the type comprising at at least one flow sensor (2) and at least one information transmission wire (6) responsible for transmitting the information coming from the flow sensor (2) to an information management center (3) The device (5) is characterized in that it further comprises, between the output of the flow sensor (2) and said information transmission wire (6), at least one sampling microcontroller (4)
Ainsi, l'information émise par le capteur de débit, sous forme par exemple d'impulsions est immédiatement transformée par le microcontrôleur d'échantillonnage (4) en mots significatifs de l'information et susceptibles d'être interprétés par la centrale de gestion de l'information (3)Thus, the information emitted by the flow sensor, in the form for example of pulses is immediately transformed by the sampling microcontroller (4) into meaningful words of the information and capable of being interpreted by the central management of information (3)
En outre, en supprimant toute transmission par fil entre le capteur de débit (2) et le microcontrôleur d'échantillonnage (4), le risque que l'information soit modifiée par des parasites est minimiseIn addition, by eliminating any wire transmission between the flow sensor (2) and the sampling microcontroller (4), the risk that the information is modified by parasites is minimized
Dans une version préférée de I invention, ledit capteur de débit (2) est un capteur à impulsion comportant au moins deux relais (7,7'), afin de permettre de déterminer le sens de circulation du fluide dans ladite canalisation (1 ) et de décompter ainsi le débit inverse de consommation En effet, il arrive fréquemment que dans une canalisation, la circulation du fluide s'inverse surtout lorsque le flux est stoppé d'une manière brutale à l'extrémité de la canalisation Or, si ce retour de fluide est suffisant, il peut provoquer la réalisation d'une impulsion par le capteur de débit (2), alors qu'en réalité, il n'y a pas de consommation, mais une consommation inverse Grâce à cette version de l'invention les impulsions produites lors des retours de fluide sont décomptées et la fiabilité du comptage s'en trouve amélioréeIn a preferred version of the invention, said flow sensor (2) is a pulse sensor comprising at least two relays (7,7 '), in order to make it possible to determine the direction of circulation of the fluid in said pipe (1) and counting down the reverse flow of consumption In fact, it often happens that in a pipe, the circulation of the fluid is reversed especially when the flow is stopped abruptly at the end of the pipe Or, if this return of fluid is sufficient, it can cause a pulse to be produced by the flow sensor (2), when in reality there is no consumption, but reverse consumption. Thanks to this version of the invention, the pulses produced during fluid returns are counted and the reliability of metering is improved
Pour ce faire, lesdits relais (7 7 ) sont de préférence disposés croisés l'un par rapport à l'autre et l'un au-dessus de l'autre, comme illustré figures 2 et 3, afin de capter alternativement le champ crée par deux aimants (8) successifs et d'occuper le moins d'espace possibleTo do this, said relays (7 7) are preferably arranged crossed with respect to one another and one above the other, as illustrated in FIGS. 2 and 3, in order to alternately pick up the field created by two successive magnets (8) and occupy as little space as possible
Les relais (7,7') sont positionnes symétriquement par rapport une verticale V, décales d'un angle A égal en degrés à 360 / [(nombre d'aimants (8) du capteur de débit) x 4], comme illustré figure 4The relays (7,7 ') are positioned symmetrically with respect to a vertical V, shifts of an angle A equal in degrees to 360 / [(number of magnets (8) of the flow sensor) x 4], as illustrated in the figure 4
Par exemple, lorsque le nombre d'aimants (8) est égal à 4, l'angle A est égal à 22,5°For example, when the number of magnets (8) is equal to 4, the angle A is equal to 22.5 °
Les figures 5 et 6 illustrent un exemple d'agencement de deux relais (7,7') dans un dispositif (5) selon l'inventionFigures 5 and 6 illustrate an example of arrangement of two relays (7,7 ') in a device (5) according to the invention
