Les interfaces de commande peuvent être à commande manuelle mais de plus en plus fréquemment, les interfaces sont asservies électroniquement. Les pompes telles que celles destinées à la circulation de l'eau dans les logements, en particulier pour le chauffage, sont asservies électroniquement d'une part pour réduire la consommation d'énergie dans le respect des règles de protection de l'environnement et d'autre part pour améliorer le confort acoustique des installations.The control interfaces can be manually controlled but more and more frequently, the interfaces are electronically controlled.

De la sorte, le circuit à horloge peut être monté ultérieurement ou pour un équipement moindre être retiré.The document EP1063751 discloses a pump unit which comprises a circulation pump driven by an electric motor. On the group housing, a group clock circuit is pluggable. The interface between the group and the clock circuit is arranged to make the group usable as a group designed without a clock circuit by removing the clock circuit of the group.

La solution est une interface comprenant un sélecteur, mobile entre deux positions de sélection, un emplacement pour une carte, des bornes reliées entre elles selon la position du sélecteur lorsqu'il n'y a pas de carte dans l'emplacement ou selon la carte lorsqu'une carte est dans l'emplacement.The invention provides an interface that is simple and inexpensive to manufacture. The solution is an interface comprising a selector, movable between two selection positions, a location for a card, terminals connected to each other according to the position of the selector when there is no card in the slot or according to the card when a card is in the slot.

La carte comporte un organe de mesure de la position du sélecteur.The card comprises a member for measuring the position of the selector.

Dans un mode de réalisation, lorsqu'une carte est dans l'emplacement, les bornes sont reliées entre elles également selon la position du sélecteur.In one embodiment, when a card is in the slot, the terminals are connected to each other also according to the position of the selector.

Avantageusement, l'interface peut comprendre en outre des bornes de liaison avec un réseau électrique. Le sélecteur peut être un sélecteur manuel.Advantageously, the interface may further comprise connection terminals with an electrical network. The selector can be a manual selector.

De préférence, la carte est amovible. La carte peut être une carte CMS.Preferably, the card is removable. The card can be a CMS card.

L'invention se rapporte aussi à un appareil comprenant l'interface décrit précédemment.The invention also relates to an apparatus comprising the interface described above.

De préférence, les bornes de l'interface sont reliées au bobinage de l'appareil, le bobinage de l'appareil étant sélectionné selon la liaison entre les bornes.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit des modes de réalisation de l'invention, donnés à titre d'exemple uniquement et en références aux dessins qui montrent :

    L'invention se rapporte à un système d'asservissement comprenant une interface comportant un emplacement pour une carte et des bornes qui sont reliées entre elles selon la présence ou l'absence d'une carte dans l'emplacement. L'interface autorise soit une configuration pour des appareils à commande manuelle, soit une configuration pour des appareils asservis électroniquement. Une même interface pouvant être appliquée dans les deux modes de fonctionnement, les coûts de fabrication sont donc réduits.
    La figure 1 montre un mode de réalisation de l'interface 10. L'interface comprend un sélecteur 12, mobile entre deux positions de sélection ; l'interface comprend aussi un emplacement 14 pour une carte. Des bornes 16 de l'interface 10 sont reliées entre elles selon la position du sélecteur 12 lorsqu'il n'y a pas de carte dans l'emplacement 14 ou selon la carte lorsqu'il y a une carte dans l'emplacement 14. L'interface est de conception simple permettant son adaptation sur des appareils asservis électroniquement ou non. Une pièce shunt montée à la place de la carte électronique permet de réaliser la version sans asservissement.
    L'interface 10 permet de relier un appareil, tel qu'un moteur ou une pompe, à un réseau électrique d'alimentation. L'interface 10 comprend des bornes d'entrée 15 pour établir une liaison avec le réseau électrique et des bornes de sortie 16 pour établir une liaison avec l'appareil à commander. La liaison avec le réseau électrique d'alimentation sur l'interface par les bornes 15 permet de simplifier la réalisation de l'alimentation de l'appareil et de réduire les coûts de fabrication des connexions avec le réseau électrique d'alimentation du condensateur de déphasage de l'appareil par des bornes 17, de la carte dans l'emplacement 14 et du moteur par les bornes 16.
    Le sélecteur 12 est un commutateur mobile entre deux positions de sélection. Le sélecteur 12 peut aussi être mobile entre plus de deux positions permettant une plus grande variété de sélection. Selon la figure 1, le sélecteur 12 est mobile entre trois positions référencées par les bornes de sortie P1, P2, P3 ; la borne d'entrée du sélecteur 12 est référencée P0. Le sélecteur 12 peut être manuel permettant à l'utilisateur de choisir la position du sélecteur qui convient pour le fonctionnement souhaité de l'appareil. Selon la figure 1, le sélecteur est par exemple mobile en rotation entre les positions de sélection. Le sélecteur 12 est relié aux bornes 16 de l'interface par l'intermédiaire de l'emplacement 14 ; sur la figure 1, le circuit électrique entre les bornes 16 et le sélecteur 12 est ouvert au niveau de l'emplacement 14.
    L'emplacement 14 est une prise permettant de brancher une carte permettant d'établir un contact entre les bornes 16 et le sélecteur 12. Lorsque l'interface 10 est utilisé avec un appareil non asservi, le circuit électrique entre la sortie 16 et le sélecteur 12 est fermé en reliant les bornes du sélecteur 12 directement aux bornes de sortie 16. La liaison directe est par exemple réalisée en établissant, en usine, un pontage entre les bornes du sélecteur 12 et les bornes de sortie 16, telle que représentée sur la figure 2. Lorsque l'interface 10 est utilisé avec un appareil asservi électroniquement, une carte comportant des composants électroniques est enfichée dans l'emplacement 14. Le circuit électrique entre les bornes de sortie 16 et le sélecteur 12 est fermé par l'intermédiaire de la carte et des composants électroniques. Sur la figure 1 l'emplacement 14 comporte des bornes référencées 140 à 149.
    Les bornes de sortie 16 de l'interface adaptent l'interface sur un appareil, une pompe ou un moteur par exemple. Les bornes de sorties 16 sont par exemple connectées au bobinage du rotor et/ou du stator de la pompe. Par exemple, lorsque l'interface est adaptée sur un moteur asynchrone à cage d'écureuil, les bornes de sorties 16 sont reliées au stator du moteur. Le bobinage de l'appareil est sélectionné selon la liaison entre les bornes 16. La liaison entre les bornes 16 est déterminée par la présence de la carte électronique. Lorsque l'emplacement 14 ne comporte pas de carte, la liaison entre les bornes 16 est déterminée par la sélection par l'utilisateur d'une position du sélecteur 12. Lorsque l'emplacement 14 comporte une carte, la connexion de la sortie 16 est déterminée par la carte. Toutefois, en présence d'une carte dans l'emplacement 14, la liaison entre les bornes de sortie 16 peut être non seulement déterminée par la carte mais aussi par la position du sélecteur 12. Sur la figure 1, les bornes de sortie 16 sont référencées 161, 162, 163, 164, 165.
    Dans un mode de réalisation, l'interface 10 comprend des bornes 17 pour brancher un condensateur CM de déphasage lorsque l'interface est adaptée sur un moteur asynchrone monophasé à condensateur de déphasage. Ceci permet de simplifier la réalisation de la connexion entre le condensateur et le moteur.
    La figure 2 montre l'interface 10 avec un appareil 28, par exemple une pompe, non asservie. L'interface 10 est dans une configuration pour des appareils à commande manuelle. Les caractéristiques en sortie de la pompe (débit/pression du fluide) peuvent être rendues dépendantes du branchement du bobinage de la pompe. Sur la figure 2, le bobinage de la pompe 28 est référencé 281, 282, 283. Il s'agit par exemple du bobinage du stator d'un moteur asynchrone à cage d'écureuil. La pompe 28 comprend des bornes référencées M1 à M8. L'interface 10 est connectée aux bornes de la pompe 28 par les bornes de sortie 161 à 165. L'interface 10 ne comprend pas de carte dans l'emplacement 14 et les bornes P0 à P3 du sélecteur 12 sont reliées respectivement aux bornes 161 à 164 de la sortie 16 par des pontages 19. Les pontages sont par exemple réalisés en usine. La borne de sortie 161 est reliée à la borne P0 par le pontage 191, la borne de sortie 162 est reliée à la borne P3 par le pontage 192, La borne de sortie 163 est reliée à la borne P2 par le pontage 193, la borne de sortie 164 est reliée à la borne P1 par le pontage 194.
    La liaison entre les bornes de sortie 16 est déterminée par la position du sélecteur 12 choisie par l'utilisateur. Ainsi,
  • lorsque le sélecteur 12 est dans la position correspondant à la borne P1 et grâce aux pontages 191 et 194, les bornes de sortie 161 et 164 sont reliées entre elles. Cette liaison a pour conséquence le branchement de la bobine 283 ;
  • lorsque le sélecteur 12 est dans la position correspondant à la borne P2 et grâce aux pontages 191 et 193, les bornes de sortie 161 et 163 sont reliées entre elles. Cette liaison a pour conséquence le branchement des bobines 282 et 283 ;
  • lorsque le sélecteur 12 est dans la position correspondant à la borne P3 et grâce aux pontages 191 et 192, les bornes de sortie 161 et 162 sont reliées entre elles. Cette liaison a pour conséquence le branchement des bobines 281, 282 et 283 ;
Other features and advantages of the invention will appear on reading the following detailed description of the embodiments of the invention, given by way of example only and with reference to the drawings which show:
  • figure 1 an interface according to the invention;
  • figure 2 , the interface of the figure 1 in manual mode;
  • figure 3 , an operating graph of the interface of the figure 2 ;
  • figure 4 , the interface of the figure 1 in a servo system;

  • figure 8 , a graph of operation according to the figure 7 .
    The invention relates to a servo system comprising an interface comprising a location for a card and terminals which are interconnected according to the presence or absence of a card in the slot. The interface allows either configuration for manually operated devices or configuration for electronically controlled devices. The same interface can be applied in both operating modes, the manufacturing costs are reduced.
    The figure 1 shows an embodiment of the interface 10. The interface comprises a selector 12, movable between two selection positions; the interface also includes a slot 14 for a card. Terminals 16 of the interface 10 are interconnected according to the position of the selector 12 when there is no card in the slot 14 or according to the card when there is a card in the slot 14. The interface is of simple design allowing its adaptation on electronically controlled devices or not. A shunt piece mounted in place of the electronic card allows the version without servocontrol.
    The interface 10 makes it possible to connect an apparatus, such as a motor or a pump, to an electrical supply network. The interface 10 comprises input terminals 15 for establishing a connection with the electrical network and output terminals 16 for establishing a connection with the apparatus to be controlled. The connection with the power supply network on the interface via the terminals 15 makes it possible to simplify the realization of the supply of the apparatus and to reduce the manufacturing costs of the connections with the power supply network of the phase-shift capacitor. of the apparatus through terminals 17, the board in slot 14 and the motor through terminals 16.
    The selector 12 is a switch movable between two selection positions. The selector 12 can also be movable between more than two positions allowing a greater variety of selection. According to figure 1 the selector 12 is movable between three positions referenced by the output terminals P1, P2, P3; the input terminal of the selector 12 is referenced P0. The selector 12 may be manual allowing the user to select the appropriate selector position for the desired operation of the apparatus. According to figure 1 , the selector is for example rotatable between the selection positions. The selector 12 is connected to the terminals 16 of the interface via the location 14; on the figure 1 , the circuit between the terminals 16 and the selector 12 is open at the location 14.
    The slot 14 is a socket for connecting a card making it possible to establish a contact between the terminals 16 and the selector 12. When the interface 10 is used with a non-controlled device, the electrical circuit between the output 16 and the selector 12 is closed by connecting the terminals of the selector 12 directly to the output terminals 16. The direct connection is for example made by establishing, in the factory, a bridging between the terminals of the selector 12 and the output terminals 16, as shown in FIG. figure 2 . When the interface 10 is used with an electronically controlled apparatus, a board comprising electronic components is plugged into the slot 14. The electrical circuit between the output terminals 16 and the selector 12 is closed via the card and electronic components. On the figure 1 the location 14 includes terminals 140 to 149.
    The output terminals 16 of the interface adapt the interface to a device, a pump or a motor for example. The output terminals 16 are for example connected to the winding of the rotor and / or the stator of the pump. For example, when the interface is fitted on an asynchronous squirrel cage motor, the output terminals 16 are connected to the stator of the motor. The winding of the apparatus is selected according to the connection between the terminals 16. The connection between the terminals 16 is determined by the presence of the electronic card. When the slot 14 has no card, the connection between the terminals 16 is determined by the selection by the user of a position of the selector 12. When the slot 14 comprises a card, the connection of the output 16 is determined by the map. However, in the presence of a card in the slot 14, the connection between the output terminals 16 can be determined not only by the card but also by the position of the selector 12. On the figure 1 the output terminals 16 are referenced 161, 162, 163, 164, 165.
    In one embodiment, the interface 10 comprises terminals 17 for connecting a phase-shift capacitor CM when the interface is fitted on a phase-shifter capacitor asynchronous single-phase motor. This simplifies the realization of the connection between the capacitor and the motor.
    The figure 2 shows the interface 10 with a device 28, for example a pump, not controlled. The interface 10 is in a configuration for manually operated apparatus. The output characteristics of the pump (flow / fluid pressure) can be made dependent on the connection of the pump winding. On the figure 2 , the winding of the pump 28 is referenced 281, 282, 283. This is for example the winding of the stator of an asynchronous motor squirrel cage. The pump 28 comprises terminals referenced M1 to M8. The interface 10 is connected to the terminals of the pump 28 via the output terminals 161 to 165. The interface 10 does not there is no card in the slot 14 and the terminals P0 to P3 of the selector 12 are respectively connected to the terminals 161 to 164 of the output 16 by bridging 19. The bridging is for example made in the factory. The output terminal 161 is connected to the terminal P0 by the bridging 191, the output terminal 162 is connected to the terminal P3 by the bridging 192, The output terminal 163 is connected to the terminal P2 by the bridging 193, the terminal output 164 is connected to the terminal P1 by the bridge 194.
    The connection between the output terminals 16 is determined by the position of the selector 12 chosen by the user. So,
  • when the selector 12 is in the position corresponding to the terminal P1 and thanks to the bridges 191 and 194, the output terminals 161 and 164 are interconnected. This connection results in the connection of the coil 283;
  • when the selector 12 is in the position corresponding to the terminal P2 and thanks to the bridges 191 and 193, the output terminals 161 and 163 are interconnected. This connection results in the connection of the coils 282 and 283;
  • when the selector 12 is in the position corresponding to the terminal P3 and thanks to the bridges 191 and 192, the output terminals 161 and 162 are interconnected. This connection results in the connection of the coils 281, 282 and 283;

La figure 3 montre la sélection manuelle par l'utilisateur d'une courbe hydraulique de fonctionnement de la pompe. La figure 3 montre un graphe indiquant le débit (m3/H) et la pression (mCE, mètre Colonne d'Eau) en sortie de pompe selon un branchement du bobinage de la pompe et une vitesse de rotation du rotor de la pompe. Le graphe montre trois courbes 1, 2, 3 représentant chacune un mode de fonctionnement de la pompe ; ces courbes correspondent chacune à une position du sélecteur 12. Le nombre de courbes et de positions du sélecteur 12 est donc donné à titre d'exemple. La courbe 1 correspond à la position P3 du sélecteur 12 et à la vitesse maximale de rotation du rotor ; la courbe 2 correspond à la position P2 du sélecteur 12 et à une vitesse intermédiaire de rotation du rotor ; la courbe 3 correspond à la position P1 du sélecteur 13 et à une vitesse minimale de rotation du rotor. L'utilisateur sélectionne alors manuellement la courbe hydraulique souhaitée du graphe de la figure 3 par la commutation du sélecteur 12. La sélection de la position du sélecteur 12 commute directement les bobines du moteur.The figure 3 shows the manual selection by the user of a hydraulic operating curve of the pump. The figure 3 shows a graph indicating the flow rate (m 3 / H) and the pressure (mCE, water column meter) at the pump outlet according to a connection of the pump winding and a speed of rotation of the pump rotor. The graph shows three curves 1, 2, 3 each representing a mode of operation of the pump; these curves each correspond to a position of the selector 12. The number of curves and positions of the selector 12 is therefore given by way of example. The curve 1 corresponds to the position P3 of the selector 12 and to the maximum speed of rotation of the rotor; curve 2 corresponds to the position P2 of the selector 12 and to an intermediate rotational speed of the rotor; curve 3 corresponds to the position P1 of the selector 13 and to a minimum speed of rotation of the rotor. The user then manually selects the desired hydraulic curve of the graph of the figure 3 by switching the selector 12. The selection of the position of the selector 12 directly switches the coils of the motor.

La figure 4 montre l'interface de la figure 1 dans un système d'asservissement. Sur la figure 4, le système d'asservissement comprend l'interface 10 et une carte 20 électronique. La carte 20 est enfichée dans l'emplacement 14. Le système d'asservissement permet une commutation électronique de la liaison entre les bornes 16 de l'interface 10. Le système d'asservissement est branché sur un appareil 28, tel qu'une pompe ; le système d'asservissement permet le réglage du fonctionnement de l'appareil 28.The figure 4 shows the interface of the figure 1 in a servo system. On the figure 4 the servo system comprises the interface 10 and an electronic card. The card 20 is plugged into the slot 14. The servocontrol system allows electronic switching of the link between the terminals 16 of the interface 10. The servo system is connected to a device 28, such as a pump ; the servo system allows the adjustment of the operation of the apparatus 28.

Les bornes de sortie 16 sont reliées entre elles par l'intermédiaire de l'emplacement 14 comportant la carte 20 et par l'intermédiaire du sélecteur 12. Selon la carte 20 enfichée, la liaison entre les bornes 16 varie. La carte 20 comporte un organe 22 de logique de commande. L'organe 22 permet de mesurer la position du sélecteur 12. L'organe 22 assure ensuite la fonction correspondante à la position du sélecteur 12. La fonction déterminée par l'organe 22 permet d'établir une liaison entre les bornes de sortie 16 de l'interface 10. L'organe 22 peut comporter des fonctions prédéfinies, programmées à l'avance en usine par exemple, ce qui rend la carte 20 immédiatement utilisable. L'organe 22 peut aussi comporter des fonctions définies par l'utilisateur lui-même ; la programmation de l'organe 22 par l'utilisateur lui-même permet à ce dernier d'enregistrer les fonctions qu'il souhaite voir appliquées à l'appareil asservi par l'interface 10.The output terminals 16 are interconnected via the location 14 having the card 20 and through the selector 12. According to the inserted card 20, the connection between the terminals 16 varies. The card 20 comprises a control logic member 22. The member 22 makes it possible to measure the position of the selector 12. The member 22 then performs the function corresponding to the position of the selector 12. The function determined by the member 22 makes it possible to establish a connection between the output terminals 16 of the interface 10. The member 22 may comprise predefined functions, programmed in advance in the factory for example, which makes the card 20 immediately usable. The member 22 may also include functions defined by the user himself; the programming of the member 22 by the user himself allows the latter to record the functions that he wants to be applied to the device controlled by the interface 10.

Avantageusement, la carte 20 est amovible ce qui permet à l'utilisateur d'utiliser une autre carte 20 comportant un organe 22 programmé différemment; l'utilisateur peut ainsi aisément modifier le fonctionnement de l'appareil 28, ou assurer son remplacement par une carte de rechange après-vente. Le fabricant peut aussi aisément différencier sa gamme de produits par différentes cartes montées en usine. Une même interface 10 permet de réaliser tout type de fonctions à l'aide de cartes électroniques appropriées installées sur l'interface 10.Advantageously, the card 20 is removable which allows the user to use another card 20 having a member 22 programmed differently; the user can easily change the operation of the device 28, or ensure its replacement by a spare after-sales card. The manufacturer can also easily differentiate its product range with different factory-installed cards. The same interface 10 makes it possible to perform any type of function using appropriate electronic cards installed on the interface 10.

Un exemple de schéma électrique de la carte 20 est représenté sur la figure 4. Avantageusement, la carte 20 est une carte de type CMS (Composants Montés en Surface) ; un tel type de carte est simple et peu onéreux à fabriquer. L'adaptation de l'interface à ce type de carte permet de rendre le système d'asservissement moins cher. La carte 20 telle que représentée sur la figure 4 comporte, outre l'organe 22, des bornes 200 à 209.An example of a circuit diagram of the card 20 is shown on the figure 4 . Advantageously, the card 20 is a CMS type card (Surface Mounted Components); such a type of card is simple and inexpensive to manufacture. Adapting the interface to this type of card makes it possible to make the servo system less expensive. The card 20 as represented on the figure 4 comprises, in addition to the member 22, terminals 200 to 209.

L'organe 22 est relié en entrée aux bornes d'entrée 201, 202, 204, 206 de la carte 20 par l'intermédiaire de composants électroniques R1, R2, R3, R4 tels que des résistances. Lorsque la carte 20 est dans l'emplacement 14, les bornes d'entrée 201, 202, 204, 206 de la carte 20 sont reliées aux bornes P0 à P3 du sélecteur 12 et les bornes de sortie 200, 203, 205, 207 de la carte 20 sont reliées aux bornes 16 de l'interface 10. Les composants R1, R2, R3, R4 permettent à l'organe 22 de détecter la position du sélecteur 12. La mesure de la position du sélecteur 12 par l'organe 22 est représentée sur la figure 5, qui est une vue en détail de la figure 4. La borne P0 du sélecteur 12 est reliée au zéro d'une alimentation +5V continue. La position du sélecteur 12 en P1-P2-P3 permet d'établir un niveau de tension distinct selon chaque position et qui sera interprété comme un état logique par l'unité de commande 22.The member 22 is input connected to the input terminals 201, 202, 204, 206 of the card 20 via electronic components R1, R2, R3, R4 such as resistors. When the card 20 is in the slot 14, the input terminals 201, 202, 204, 206 of the card 20 are connected to the terminals P0 to P3 of the selector 12 and the output terminals 200, 203, 205, 207 of the card 20 are connected to the terminals 16 of the interface 10. The components R1, R2, R3, R4 allow the member 22 to detect the position of the selector 12. The measurement of the position of the selector 12 by the member 22 is represented on the figure 5 which is a detailed view of the figure 4 . The terminal P0 of the selector 12 is connected to the zero of a + 5V DC supply. The position of the selector 12 in P1-P2-P3 makes it possible to establish a distinct voltage level according to each position and which will be interpreted as a logic state by the control unit 22.

L'organe 22 est relié en sortie à des triacs Y1, Y2, Y3. Les triacs sont reliés à la borne de sortie 200 et respectivement aux bornes de sortie 203, 205, 207 de la carte 20. Le nombre de bornes d'entrée et de sortie de la carte et le nombre de triacs utilisés ne sont pas limités aux nombres décrits.The member 22 is connected at the output to triacs Y1, Y2, Y3. The triacs are connected to the output terminal 200 and respectively to the output terminals 203, 205, 207 of the 20. The number of input and output terminals on the board and the number of triacs used are not limited to the numbers described.

La figure 6 est une vue en détail de la figure 4 et représente la fonction des bornes 208 et 209. Les bornes 208 et 209 de la carte 20 sont au même potentiel. La borne 209 est par exemple utilisée avec la borne 203 pour l'alimentation électrique de la carte 20. La borne 208 est par exemple utilisée avec la borne 207 pour la fonction de dégommage, c'est-à-dire l'augmentation momentanée de la valeur du condensateur de déphasage du moteur CM, à l'aide d'un condensateur additionnel en parallèle, afin d'augmenter le couple moteur.The figure 6 is a detailed view of the figure 4 and represents the function of the terminals 208 and 209. The terminals 208 and 209 of the card 20 are at the same potential. The terminal 209 is for example used with the terminal 203 for the power supply of the card 20. The terminal 208 is for example used with the terminal 207 for the function of degumming, that is to say the momentary increase of the value of the phase shift capacitor of the motor CM, with the aid of an additional capacitor in parallel, in order to increase the motor torque.

Sur la figure 4, selon la position mesurée du sélecteur 12 par l'organe 22 et selon les fonctions de l'organe 22, celui-ci active un triac. L'activation d'un triac établit une liaison entre deux bornes 16 particulières de l'interface 10 et un branchement des bobines de l'appareil 28. Ainsi :

  • l'activation du triac Y1 permet d'établir une liaison entre les bornes 161 et 162. Cette connexion a pour conséquence le branchement des bobines 281, 282 et 283 ;
  • l'activation du triac Y2 permet d'établir une liaison entre les bornes 161 et 163. Cette connexion a pour conséquence le branchement des bobines 282 et 283 ;
  • l'activation du triac Y3 permet d'établir une liaison entre les bornes 161 et 164. Cette connexion a pour conséquence le branchement de la bobine 283.
On the figure 4 , according to the measured position of the selector 12 by the member 22 and according to the functions of the member 22, it activates a triac. The activation of a triac establishes a connection between two particular terminals 16 of the interface 10 and a connection of the coils of the apparatus 28. Thus:
  • the activation of the triac Y1 makes it possible to establish a link between the terminals 161 and 162. This connection results in the connection of the coils 281, 282 and 283;
  • the activation of triac Y2 makes it possible to establish a connection between the terminals 161 and 163. This connection results in the connection of the coils 282 and 283;
  • the activation of triac Y3 makes it possible to establish a connection between the terminals 161 and 164. This connection results in the connection of the coil 283.

La figure 7 montre un exemple d'asservissement du fonctionnement de l'interface de la figure 4. La figure 7 montre un graphe comportant les courbes hydrauliques 1, 2, 3 figurant sur la figure 3 et indiquant le débit (en m3/H) et la pression (mCE, mètre Colonne d'Eau) en sortie de pompe selon la vitesse de rotation du moteur de la pompe. Le graphe montre aussi des courbes A, B et C indiquant des niveaux de hauteur manométrique suivant le mode d'asservissement programmé. Les niveaux de hauteur manométrique sont des limites de fonctionnement de l'appareil par définition de pressions limites supérieures et/ou inférieures. Dans le cas d'une pompe, son fonctionnement peut être contrôlé par la pression en sortie de la pompe. Les niveaux de hauteur manométrique, pré-définis en laboratoire par exemple, sont de telle sorte qu'à chacune des positions du sélecteur corresponde l'un de ces niveaux. Les niveaux de hauteur manométrique peuvent être à pression constante ou à pression variable ou à une combinaison des deux. Sur la figure 7, ces niveaux sont variables. Un mode de fonctionnement consiste à sélectionner un niveau de hauteur manométrique (choix d'une courbe A, B ou C) par la sélection d'une position du sélecteur 12. L'interface 10 effectue l'asservissement électronique en modifiant la liaison entre les bornes 16 de sortie, provoquant ainsi la commutation électronique des bobines de l'appareil 28 ; la commutation des bobines provoque la commutation automatique sur les courbes hydrauliques 1, 2, 3 combinées aux courbes d'asservissement A, B, C suivant les fonctions préprogrammées sur la carte 20.The figure 7 shows an example of slaving the operation of the interface of the figure 4 . The figure 7 shows a graph with the hydraulic curves 1, 2, 3 shown on the figure 3 and indicating the flow rate (in m 3 / H) and the pressure (mCE, water column meter) at the pump outlet according to the speed of rotation of the pump motor. The graph also shows curves A, B and C indicating manometric height levels according to the programmed servo mode. Manometric head levels are operating limits of the apparatus by defining upper and / or lower limit pressures. In the case of a pump, its operation can be controlled by the pressure at the outlet of the pump. The manometric height levels, pre-defined in the laboratory for example, are such that at each of the positions of the selector corresponds to one of these levels. Manometric head levels may be at constant pressure or variable pressure or a combination of both. On the figure 7 these levels are variable. One operating mode consists in selecting a manometric height level (choice of a curve A, B or C) by selecting a position of the selector 12. The interface 10 performs the electronic control by modifying the connection between the 16 output terminals, thereby causing the electronic switching of the coils of the apparatus 28; the switching of the coils causes the commutation automatic on the hydraulic curves 1, 2, 3 combined with servo control curves A, B, C according to the functions preprogrammed on the card 20.

Un exemple de fonctionnement va être donné en référence à la figure 8, l'appareil étant par exemple une pompe. Le sélecteur 12 est positionné sur une position permettant la sélection de la courbe B, par exemple la position P2. Une largeur de bande ΔB est prédéterminée avec comme axe central la courbe B et comme limites supérieure et inférieure, respectivement les courbes B1 et B2. La bande définit les limites ou seuils de permutation automatique entre les 3 courbes hydrauliques 1, 2, 3.An example of operation will be given with reference to the figure 8 , the device being for example a pump. The selector 12 is positioned at a position permitting the selection of the curve B, for example the position P2. A bandwidth ΔB is predetermined with the curve B as the central axis and the curves B1 and B2 as the upper and lower limits respectively. The band defines the limits or thresholds for automatic switching between the 3 hydraulic curves 1, 2, 3.

Au démarrage la pompe fonctionne à une vitesse minimale correspondant à la courbe hydraulique 3 dans l'exemple et est maintenue à cet état de fonctionnement pendant un court instant pour la stabilisation de l'électronique de commande et de l'information du paramètre d'asservissement. Le point de fonctionnement de la pompe dépend des pertes de charge de l'installation dans laquelle est montée la pompe. Les pertes de charge sont caractérisées par les courbes Pc1, Pc2, Pc3 d'équation y = ax2, le coefficient « a » correspondant à une valeur de perte de charge : la valeur de a augmente lorsque une vanne de l'installation est fermée, la valeur de a diminue lorsque une vanne est ouverte. Selon les pertes de charges de l'installation, le point de fonctionnement de la pompe se situe aux points Pd1, Pd2, Pd3.At startup the pump operates at a minimum speed corresponding to the hydraulic curve 3 in the example and is maintained in this operating state for a short time for the stabilization of the control electronics and the information of the servo parameter . The operating point of the pump depends on the pressure drops of the installation in which the pump is mounted. The pressure losses are characterized by the curves Pc1, Pc2, Pc3 of equation y = ax 2 , the coefficient "a" corresponding to a value of pressure loss: the value of a increases when a valve of the installation is closed , the value of a decreases when a valve is opened. According to the pressure losses of the installation, the operating point of the pump is at points Pd1, Pd2, Pd3.

Après la phase de démarrage écoulée, le système d'asservissement gère le fonctionnement de la pompe suivant le débit de celle-ci :

  • sur une augmentation du débit (diminution des pertes de charge de l'installation correspondant à une ouverture d'une vanne), le système d'asservissement permute automatiquement les courbes hydrauliques 3 vers 2 et 2 vers 1, lorsque respectivement les seuils minimaux Pmin3 et Pmin2 sont atteints ;
  • sur une diminution du débit (augmentation des pertes de charge de l'installation correspondant à une fermeture d'une vanne), le système d'asservissement permute automatiquement dans le sens inverse les courbes hydrauliques 1 vers 2 et 2 vers 3, lorsque respectivement les seuils maximaux Pmax1 et Pmax2 sont atteints.
After the startup phase has elapsed, the servo system manages the operation of the pump according to the flow thereof:
  • on an increase of the flow rate (decrease of the losses of load of the installation corresponding to an opening of a valve), the servo system automatically switches the hydraulic curves 3 towards 2 and 2 towards 1, when respectively the minimum thresholds Pmin3 and Pmin2 are affected;
  • on a reduction of the flow rate (increase of the losses of load of the installation corresponding to a closing of a valve), the servo system automatically switches in the opposite direction the hydraulic curves 1 to 2 and 2 to 3, when respectively the maximum thresholds Pmax1 and Pmax2 are reached.

Dans les plages de débit minimal (Dmin) ou de débit maximal (Dmax) la pompe fonctionne respectivement sur les courbes hydrauliques 3 ou 1.In the minimum flow (Dmin) or maximum flow (Dmax) ranges, the pump runs on hydraulic curves 3 or 1, respectively.

Le système d'asservissement permet à l'utilisateur de régler le démarrage, le fonctionnement et éventuellement l'arrêt de la pompe dans des conditions souhaitées. Ceci permet d'une part de réduire la consommation d'énergie dans les règles de protection de l'environnement, et d'autre part, d'améliorer le confort acoustique des installations.The servo system allows the user to set the starting, operation and possibly stopping of the pump under desired conditions. This allows on the one hand to reduce the energy consumption in the rules of protection of the environment and, on the other hand, to improve the acoustic comfort of the installations.

Le système ainsi défini offre la possibilité de réaliser tout type de fonctions à l'aide de cartes électroniques appropriées, connectées dans l'emplacement 14 de la même interface 10. A titre d'exemple de fonctions envisagées :

  • une fonction déblocage du moteur + deux niveaux de hauteur manométrique asservis,
  • une courbe hydraulique non asservie + deux niveaux de hauteur manométrique asservis,
  • etc...
The system thus defined offers the possibility of performing any type of function using appropriate electronic cards, connected in the slot 14 of the same interface 10. As an example of the functions envisaged:
  • an unlock function of the motor + two servo-controlled head levels,
  • a non-servocontrolled hydraulic curve + two servo-controlled head levels,
  • etc ...

Bien entendu, la présente invention n'est pas limitée aux modes de réalisations décrits à titre d'exemple; ainsi, le nombre de bornes d'entrée et de sortie de l'interface peut varier....Of course, the present invention is not limited to the embodiments described by way of example; thus, the number of input and output terminals of the interface can vary ....
