Abstract
Description
L'invention concerne un dispositif associé à un organe à fonctionnement cyclique, permettant le comptage du nombre de cycles effectués et le stockage provisoire des informations dans une mémoire statique effaçable logée dans un espace lié à l'organe principal. The invention relates to a device associated with a cyclically operating member, allowing the counting of the number of cycles carried out and the temporary storage of information in an erasable static memory housed in a space linked to the main member.
Elle comprend également un dispositif indépendant et mobile destiné à recueillir et afficher les informations contenues dans la mémoire pour permettre leur lecture. II est équipé d'organes permettant la remise à zéro de l'écran d'affichage et de la mémoire de stockage. It also includes an independent and mobile device intended to collect and display the information contained in the memory so that it can be read. It is equipped with members enabling the display screen and the storage memory to be reset to zero.
Le dispositif selon l'invention peut être associé à différents organes, comme des distributeurs d'objets divers, de billets ou de tickets, de doses de produits liquides, des portillons d'accès à des locaux protégés, etc... En fait, chaque fois qu'il faut comptabiliser le nombre d'opérations effectué par l'organe considéré et qu'il est souhaité de faire des contrôles, soit intermédiaires sans remise à zéro, soit avec remise à zéro après lecture du total affiché. The device according to the invention can be associated with different organs, such as distributors of various objects, tickets or tickets, doses of liquid products, gates for access to protected premises, etc. In fact, each time the number of operations carried out by the body in question has to be recorded and it is desired to carry out checks, either intermediate without resetting, or with resetting after reading the total displayed.
Les textes et les figures donnés à titre d'exemples non limitatifs pour l'illustration du dispositif décrivent l'adaptation à un distributeur de produits ou d'objets quelconques, mais l'association avec tout autre organe à fonctionnement cyclique correspond aux mêmes critères revendiqués pour l'invention. The texts and the figures given by way of nonlimiting examples for the illustration of the device describe the adaptation to a dispenser of any products or objects, but the association with any other organ with cyclic operation corresponds to the same claimed criteria. for the invention.
Les figures représentent les shémas, les moyens et leurs connections utilisés pour réaliser des versions de l'objet de rinvention. The figures represent the diagrams, the means and their connections used to produce versions of the object of the invention.
Dans la figure 1, L'organe à équiper est un distributeur 1 délivrant un objet ou une dose par cycle de fonctionnement exécuté par l'actionneur 2. Le microprocesseur 3, alimenté par une source d'énergie électrique extérieure raccordée à la prise 4, déclenche le cycle chaque fois que le contacteur 5 est actionné. In FIG. 1, the member to be equipped is a dispenser 1 delivering an object or a dose per operating cycle executed by the actuator 2. The microprocessor 3, supplied by an external electrical energy source connected to the socket 4, triggers the cycle each time switch 5 is pressed.
Pour chaque cycle, une information est transmise à la mémoire 6 et vient s'ajouter au total déjà comptabilisé. For each cycle, information is transmitted to memory 6 and is added to the total already recorded.
Le microprocesseur 3 est raccordé à la cellule 7 comportant une diode 8 pouvant émettre une lumière infrarouge et une cellule photoélectrique 9 sensible à la lumière infrarouge. The microprocessor 3 is connected to the cell 7 comprising a diode 8 capable of emitting infrared light and a photoelectric cell 9 sensitive to infrared light.
La figure 2 représente un lecteur mobile comprenant une cellule 10, identique ou de même nature que la cellule 7 comportant une diode 11 pouvant émettre une lumière infrarouge et une cellule photoélectrique 12 sensible à la lumière infrarouge, raccordée à un microprocesseur 13. FIG. 2 represents a mobile reader comprising a cell 10, identical or of the same kind as cell 7 comprising a diode 11 capable of emitting infrared light and a photoelectric cell 12 sensitive to infrared light, connected to a microprocessor 13.
Une source électrique 14, qui peut être une pile ou un accumulateur, assure l'alimentation après passage par l'interrupteur de mise sous tension 15. An electric source 14, which can be a battery or an accumulator, provides the power after passage through the power-on switch 15.
Le microprocesseur 13 est également raccordé à un écran d'affichage 16, qui peut être à cristaux liquides, à diodes luminescentes ou autre. The microprocessor 13 is also connected to a display screen 16, which may be liquid crystal, light emitting diodes or the like.
Lorsque l'interrupteur 15 réalise la mise sous tension qui est confirmée par l'éclairement de la diode lumineuse 17, le microprocesseur est agencé pour provoquer une émission périodique, par exemple 10 fois par seconde, d'un signal lumineux codé, par l'intermédiaire de la diode 11. When the switch 15 performs the power-up which is confirmed by the illumination of the light diode 17, the microprocessor is arranged to cause a periodic emission, for example 10 times per second, of a coded light signal, by the diode 11.
Si les cellules 7 et 10 sont mises à proximité l'une de l'autre, comme représenté sur la Figure 3, la cellule photoélectrique 9 recevra le signal codé émis par la diode 1 1 et transmettra ce signal au microprocesseur 3 programmé pour analyser ce signal et qui, après reconnaissance, fera émettre un autre signal lumineux codé à la diode 8, reçu par la cellule 12, transmis enfin au microprocesseur 13. If cells 7 and 10 are placed close to each other, as shown in Figure 3, the photoelectric cell 9 will receive the coded signal emitted by the diode 1 1 and will transmit this signal to the microprocessor 3 programmed to analyze this signal and which, after recognition, will send another light signal coded at diode 8, received by cell 12, finally transmitted to microprocessor 13.
La liaison est établie entre les deux microprocesseurs. The link is established between the two microprocessors.
Le microprocesseur 3 interroge alors la mémoire 6, recueille ses informations et les transmet au microprocesseur 13, par signaux codés émis par la diode 8 et reçus par la cellule 12. The microprocessor 3 then interrogates the memory 6, collects its information and transmits it to the microprocessor 13, by coded signals emitted by the diode 8 and received by the cell 12.
Une opération de contrôle est réalisée par le microprocesseur 13 qui renvoie ces informations au microprocesseur 3 par les mêmes chemins. Après vérification de l'identité des informations, la liaison est avalisée, et l'écran 16 reçoit du microprocesseur 13 les signaux lui permettant d'afficher en clair la valeur stockée dans la mémoire 6 et retenue par le microprocesseur 13. A control operation is carried out by the microprocessor 13 which returns this information to the microprocessor 3 by the same paths. After verifying the identity of the information, the link is endorsed, and the screen 16 receives the signals from the microprocessor 13 allowing it to display in clear the value stored in the memory 6 and retained by the microprocessor 13.
Cet état est rappelé par l'éclairement de la diode lumineuse 18, de préférence de couleur différente que celle de la diode 17. This state is recalled by the illumination of the light diode 18, preferably of a different color than that of the diode 17.
Le microprocesseur 13 est agencé de telle manière que l'affichage soit permanent sur l'écran 16, même après que le lecteur mobile soit éloigné de l'organe principal 1 et que le couplage entre les deux microprocesseurs soit rompu. The microprocessor 13 is arranged in such a way that the display is permanent on the screen 16, even after the mobile reader is distant from the main member 1 and the coupling between the two microprocessors is broken.
La remise à zéro de l'écran 16 et le retour à la position de veille du microprocesseur 13 et de la cellule 10 se font par l'action de l'interrupteur 19 relié au microprocesseur 13 programmé en conséquence. The reset of the screen 16 and the return to the standby position of the microprocessor 13 and of the cell 10 are effected by the action of the switch 19 connected to the microprocessor 13 programmed accordingly.
Le lecteur est alors prêt à effectuer une autre opération. The reader is now ready to perform another operation.
Si au lieu d'agir sur l'interrupteur 19, on coupe l'alimentation par l'interrupteur 15, on obtient les mêmes effets, mais l'état de veille ne sera rétabli que lors de la remise sous tension. If instead of acting on the switch 19, the power is cut by the switch 15, the same effects are obtained, but the standby state will not be restored until the power is restored.
Enfin, le microprocesseur 3 est agencé de telle manière que si on agit sur l'interrupteur 19 avant d'avoir rompu le contact optique entre les cellules 7 et 10, on effectue parallèlement la remise à zéro de la mémoire 6. Finally, the microprocessor 3 is arranged in such a way that if one acts on the switch 19 before having broken the optical contact between the cells 7 and 10, the memory 6 is reset to zero.
Bien entendu, on peut obtenir des résultats identiques en faisant appel à des cellules comprenant des émetteurs et des récepteurs acoustiques, ultra sonores, hertziens, magnétiques ou utilisant des diodes laser et des récepteurs apropriés. Of course, identical results can be obtained by using cells comprising acoustic, ultra-sonic, radio, magnetic transmitters and receivers or using suitable laser diodes and receivers.
La figure 4 représente une disposition particulière des dispositifs selon l'invention, où le lecteur se raccorde à l'organe principal par un cordon 20 et une fiche 21 à contacts électriques directs branchée sur une prise 22 reliée au microprocesseur 3. FIG. 4 represents a particular arrangement of the devices according to the invention, where the reader is connected to the main member by a cord 20 and a plug 21 with direct electrical contacts connected to a socket 22 connected to the microprocessor 3.
Les protocoles de liaison, de contrôle, de validation, et les processus de lecture, d'affichage et de remise à zéro sont les mêmes. The connection, control, validation protocols, and the read, display and reset processes are the same.
La figure 5 représente un lecteur suivant l'invention où l'alimentation électrique se fait par le raccordement d'une fiche 24 à une prise 23 reliée au microprocesseur 3, avec une source extérieure 25, par exemple un transformateur abaisseur de tension, associé à un redresseur de courant, branché sur une source fixe 26 du réseau de distribution. FIG. 5 represents a reader according to the invention where the electrical supply is made by the connection of a plug 24 to a socket 23 connected to the microprocessor 3, with an external source 25, for example a step-down transformer, associated with a current rectifier, connected to a fixed source 26 of the distribution network.
La figure 6 représente une version du dispositif selon l'invention particulièrement adaptée à un organe distributeur de doses de produits liquides. Le produit à distribuer est contenu dans le réservoir 27 raccordé au doseur, et la dose est calibrée par le volume précis d'une cavité 28 alternativement remplie à partir du réservoir, puis délivrée lors de l'action sur le déclencheur 5. FIG. 6 represents a version of the device according to the invention particularly suitable for a device for dispensing doses of liquid products. The product to be dispensed is contained in the reservoir 27 connected to the dispenser, and the dose is calibrated by the precise volume of a cavity 28 alternately filled from the reservoir, then delivered during the action on the trigger 5.
Un contrôleur de remplissage, relié au microprocesseur 3, est agencé pour interdire la délivrance d'une dose qui serait incomplète et donc indûment comptabilisée. Cette disposition est particulièrement intéressante pour éviter de comptabiliser le dernier écoulement de liquide du réservoir 27, dont le volume peut varier de zéro à 100 % de la dose attendue. A filling controller, connected to the microprocessor 3, is arranged to prohibit the delivery of a dose which would be incomplete and therefore unduly counted. This arrangement is particularly advantageous in order to avoid counting the last flow of liquid from the reservoir 27, the volume of which can vary from zero to 100% of the expected dose.
Une réalisation particulière, mais non exclusive, d'un contrôleur de remplissage consiste à disposer dans la cavité 28, deux électrodes 29 et 30, alimentées sous une très faible tension et associées à un détecteur de courant très sensible. L'électrode 29 étant disposée au point le plus haut de respace réservé au liquide, aucun courant ne pourra passer entre les deux électrodes tant que le niveau du liquide n'aura pas atteint le point le plus haut. Dès que l'électrode 29 sera recouverte, la conductibilité du liquide, même infime, permettra un faible courant qui sera détecté et mémorisé par le microprocesseur 3. Lors de l'action sur le déclencheur 5, le vidage de la cavité et le comptage de l'opération dans le mémoire 6 seront autorisés. A particular, but not exclusive, embodiment of a filling controller consists in placing in the cavity 28, two electrodes 29 and 30, supplied with a very low voltage and associated with a very sensitive current detector. Since the electrode 29 is placed at the highest point of the space reserved for the liquid, no current can pass between the two electrodes until the level of the liquid has reached the highest point. As soon as the electrode 29 is covered, the conductivity of the liquid, even a small one, will allow a weak current which will be detected and memorized by the microprocessor 3. During the action on the trigger 5, the emptying of the cavity and the counting of the operation in memory 6 will be authorized.
Si le niveau atteint par le liquide dans la cavité 28 n'est pas suffisant pour recouvrir l'électrode 29, une action sur le déclencheur 5 restera sans effet, ni sur le vidage de la cavité 28, ni sur la mémoire de comptage 6. If the level reached by the liquid in the cavity 28 is not sufficient to cover the electrode 29, an action on the trigger 5 will have no effect, neither on the emptying of the cavity 28, nor on the counting memory 6.
Pour éviter une consommation de courant inutile ainsi que d'éventuels effets d'électrolyse du liquide, il est possible de prévoir la coupure d'alimentation des électrodes dès la mémorisation du niveau par le microprocesseur 3, le contact étant automatiquement rétabli dès que la dose contenue dans la cavité 28 est évacuée. To avoid unnecessary current consumption as well as possible effects of liquid electrolysis, it is possible to provide for the electrodes being cut off as soon as the level is memorized by the microprocessor 3, the contact being automatically reestablished as soon as the dose contained in the cavity 28 is evacuated.
La figure 7 représente une évolution du dispositif selon l'invention, dans laquelle il est prévu un contrôle de complet remplissage et de complet vidage de la cavité de mesure 28. Dans cette version dérivée de celle représentée sur la figure 6, on dispose trois électrodes, I'électrode 29 toujours disposée au point le plus haut de la cavité 28, I'électrode 31 située au point le plus bas de la cavité 28, et l'électrode 30 disposée très légèrement au dessus de l'électrode 31. FIG. 7 represents an evolution of the device according to the invention, in which a control of complete filling and complete emptying of the measurement cavity 28 is provided. In this version derived from that represented in FIG. 6, there are three electrodes , The electrode 29 always disposed at the highest point of the cavity 28, the electrode 31 located at the lowest point of the cavity 28, and the electrode 30 disposed very slightly above the electrode 31.
L'électrode 30 est raccordée à un pôle commun à deux circuits électriques,
I'un fournissant une tension à l'électrode 29, L'autre fournissant une tension à l'électrode 31. Tant que les circuits seront sous tension et que la cavité 28 contiendra tant soit peu de liquide, il existera un courant entre les électrodes 30 et 31. On comprend aisément que l'indication de complet remplissage est obtenue, comme dans la disposition précédente, lorsque l'électrode 29 étant recouverte par le liquide, il est possible de détecter le passage d'un courant entre les électrodes 29 et 30. De même, I'indication de complet vidage sera donnée lorsque le niveau du liquide aura quitté l'électrode 30 ce qui permettra de détecter l'interruption du courant entre les électrode 30 et 31 et de mémoriser cet état dans le microprocesseur 3.The electrode 30 is connected to a pole common to two electrical circuits,
One supplying a voltage to the electrode 29, the other supplying a voltage to the electrode 31. As long as the circuits are energized and the cavity 28 contains even a little liquid, there will be a current between the electrodes 30 and 31. It is easily understood that the indication of complete filling is obtained, as in the previous arrangement, when the electrode 29 being covered by the liquid, it is possible to detect the passage of a current between the electrodes 29 and 30. Likewise, the indication of complete emptying will be given when the level of the liquid has left electrode 30, which will make it possible to detect the interruption of the current between electrodes 30 and 31 and to store this state in microprocessor 3.
Bien entendu, dans cette configuration comme dans la précédente, suivant la taille ou la nature de l'organe distributeur à équiper et rimportance de la cavité 28, toute autre réalisation d'un contrôleur de remplissage et éventuellement de vidage permettant d'envoyer un message vers le microprocesseur 3 est conforme à l'invention. On peut citer, comme exemples non limitatifs, un dispositif de flotteur avec contacts en position haute et basse, un dispositif optique utilisant la diffraction d'un rayon lumineux dans le liquide, un dispositif sensible à la pression induite par la hauteur du liquide dans la cavité de mesure et s'exerçant sur une membrane reliée à un manostat à contacts électriques, un dispositif utilisant la réflexion d'ondes ultrasonores sur la surface libre du liquide et indiquant les différents niveaux atteints, etc... Of course, in this configuration as in the previous one, depending on the size or nature of the dispensing member to be fitted and the importance of the cavity 28, any other embodiment of a filling and possibly emptying controller making it possible to send a message to microprocessor 3 is in accordance with the invention. Mention may be made, as nonlimiting examples, of a float device with contacts in the high and low position, an optical device using the diffraction of a light ray in the liquid, a device sensitive to the pressure induced by the height of the liquid in the measurement cavity and acting on a membrane connected to a pressure switch with electrical contacts, a device using the reflection of ultrasonic waves on the free surface of the liquid and indicating the different levels reached, etc ...
