Description

L'invention concerne le domaine des installations d'éléments enroulables motorisées. Elle concerne plus particulièrement un procédé de commande automatisée d'une installation comprenant un élément enroulable motorisé, ou volet roulant motorisé.The invention relates to the field of installations of motorized winding elements. It relates more particularly to a method of automated control of an installation comprising a motorized rolling element, or motorized roller shutter.

Les installations d'écran ou d'éléments enroulables motorisés connues comprennent en général un élément enroulable ou écran, tel qu'un tablier formé de lames articulées et empilables, ou encore un ensemble comprenant une toile et une barre de charge lestée, l'écran étant enroulable autour d'un tube d'enroulement situé dans la partie supérieure de l'installation, grâce à des moyens d'entraînement motorisés ou actionneur. La lame finale, ou lame inférieure située à l'extrémité inférieure du tablier ou barre de charge de la toile, est guidée par des rails situés de part et d'autre d'une ouverture à masquer. Cette lame inférieure peut être déplacée entre une position extrême inférieure, par exemple en contact avec un seuil de l'ouverture et une position extrême supérieure, par exemple au niveau d'un caisson dans lequel s'enroule l'écran. Ces installations peuvent comprendre également des positions particulières de la barre de la lame inférieure ou de la barre de charge de l'écran, associées à des positions particulières en mémoire de l'actionneur. Ces positions particulières sont par exemple une ou plusieurs positions intermédiaires entre les deux positions extrêmes, une position de verrouillage, une position d'orientation, pour des écrans à lames orientables, ou une position de projection, pour des volets roulants disposant d'un mécanisme leur permettant d'être déplacés dans un plan sécant à leur plan de déroulement principal.Known screen installations or motorized roll-up elements generally comprise a roll-up element or screen, such as an apron formed of articulated and stackable blades, or else an assembly comprising a canvas and a weighted load bar, the screen being rollable around a winding tube located in the upper part of the installation, by means of motorized drive means or actuator. The final blade, or lower blade located at the lower end of the apron or load bar of the canvas, is guided by rails located on either side of an opening to be masked. This lower blade can be moved between a lower extreme position, for example in contact with a threshold of the opening, and an upper extreme position, for example at the level of a box in which the screen is wound. These installations can also include particular positions of the bar of the lower blade or of the load bar of the screen, associated with particular positions in the memory of the actuator. These particular positions are for example one or more intermediate positions between the two extreme positions, a locking position, an orientation position, for screens with adjustable slats, or a projection position, for rolling shutters having a mechanism. allowing them to be moved in a plane secant to their main unwinding plane.

Des moyens de commande spécifiques sont généralement prévus pour permettre le déplacement de l'écran jusqu'à une position particulière. Ces moyens de commande spécifiques sont par exemple un bouton dédié sur une unité de commande à distance telle qu'une télécommande ou une ergonomie dédiée, par exemple un appui plus long sur une touche, l'appui court sur cette même touche ayant déjà une autre fonction de commande.Specific control means are generally provided to allow movement of the screen to a particular position. These specific control means are for example a dedicated button on a remote control unit such as a remote control or a dedicated ergonomics, for example a longer press on a key, the short press on this same key already having another control function.

Une position particulière est par exemple une position de verrouillage, l'installation comprenant alors des moyens de verrouillage permettant de maintenir la lame inférieure ou la barre de charge de l'écran dans une position déterminée tout en évitant que celle-ci ne soit soulevée par effraction ou ne claque sous les actions du vent.A particular position is for example a locking position, the installation then comprising locking means making it possible to maintain the lower blade or the load bar of the screen in a determined position while preventing the latter from being lifted by break-in or slam under the actions of the wind.

A cet effet, les moyens de verrouillage de telles installations sont configurés de sorte que lors du déroulement de l'écran, la lame finale de l'écran, c'est à dire la lame inférieure du volet à lames articulées ou la barre de charge d'une toile, entre dans le moyen de verrouillage, puis, à la suite d'un mouvement inverse d'enroulement, se bloque dans le moyen de verrouillage. Pour déverrouiller et ouvrir de nouveau le volet, il est nécessaire de d'abord déplacer la lame finale dans le sens du déroulement jusqu'à une certaine position avant de pouvoir enrouler l'écran.For this purpose, the locking means of such installations are configured so that when the screen is unwinding, the final slat of the screen, that is to say the lower slat of the hinged slat shutter or the load bar of a canvas, enters the locking means, then, following a reverse winding movement, becomes blocked in the locking means. To unlock and reopen the shutter, it is necessary to first move the final slat in the unwinding direction to a certain position before being able to roll up the screen.

De manière assez similaire, un volet roulant à lames orientables peut comprendre un mécanisme de basculement des lames, configuré de sorte que lors du déplacement du tablier dans un premier sens, par exemple lors d'un déroulement du tablier, la lame inférieure du volet entre dans le mécanisme de basculement puis, à la suite d'un mouvement inverse, dans un deuxième sens, se bloque dans le mécanisme de basculement. La poursuite du mouvement dans le deuxième sens, par exemple l'enroulement, permet l'orientation des lames, qui sont autrement en position fermée. Pour dégager le tablier du mécanisme de basculement, il est nécessaire de d'abord déplacer le tablier dans le premier sens, en déroulement, jusqu'à une certaine position, ce qui a pour effet de refermer les lames avant de dégager la lame finale du mécanisme de basculement. Une telle installation est par exemple décrite dans le document EP2226462 .Rather similarly, a roller shutter with adjustable slats may include a slat tilting mechanism, configured so that when moving the apron in a first direction, for example when unwinding the apron, the lower slat of the shutter enters. in the tilting mechanism and then, following a reverse movement, in a second direction, locks in the tilting mechanism. Continuing movement in the second direction, eg winding, allows orientation of the blades, which are otherwise in the closed position. To release the apron from the tilting mechanism, it is necessary to first move the apron in the first direction, unwinding, to a certain position, which has the effect of closing the slats before releasing the final slat from the tilting mechanism. Such an installation is for example described in the document EP2226462 .

Un autre exemple de réalisation d'installation comprenant une position particulière est celui du volet roulant à projection, par exemple tel que décrit dans les documents FR2942051 A1 , FR2962759 , FR2941996 ou EP2783063 . L'installation d'écran comprend alors un mécanisme de projection de sorte que lors du déplacement dans un premier sens, par exemple lors d'un déroulement du tablier dans un premier plan, la lame inférieure du tablier entre dans le mécanisme de projection puis, à la suite d'un mouvement dans un deuxième sens inverse, se bloque dans le mécanisme. La poursuite du mouvement dans le deuxième sens permet l'actionnement d'un bras de projection et le déploiement d'un cadre de l'écran dans un plan sécant au premier plan.Another example of an installation embodiment comprising a particular position is that of the rolling shutter with projection, for example as described in the documents FR2942051 A1 , FR2962759 , FR2941996 or EP2783063 . The screen installation then comprises a projection mechanism so that during movement in a first direction, for example during an unwinding of the apron in a first plane, the lower blade of the apron enters the projection mechanism then, as a result of a movement in a second opposite direction, hangs in the mechanism. The Further movement in the second direction allows the actuation of a projection arm and the deployment of a screen frame in a plane intersecting the foreground.

Les moyens de verrouillage, les mécanismes de basculement ou les mécanismes de projection peuvent être qualifiés collectivement de mécanismes d'ancrage ou de blocage, et sont associés à des positions particulières.The locking means, the tilting mechanisms or the projection mechanisms can be referred to collectively as anchoring or locking mechanisms, and are associated with particular positions.

D'autres positions particulières, telles que des positions particulières, ne sont associées à aucun mécanisme, mais nécessitent également d'être réglées individuellement, par une ergonomie de réglage spécifique.Other particular positions, such as particular positions, are not associated with any mechanism, but also need to be adjusted individually, by specific adjustment ergonomics.

Les différents déplacements de l'écran sont de préférence effectués de manière motorisée. Un actionneur est généralement placé dans le tube d'enroulement et répond à des ordres émanant d'un utilisateur par l'intermédiaire d'une interface de commande telle qu'une télécommande ou une interface murale. L'actionneur comprend un moteur et un réducteur ainsi qu'une unité électronique de commande comprenant des moyens électriques ou électroniques de gestion du mouvement de l'écran en fonction des ordres reçus et en fonction d'événements détectés. Ces moyens électriques ou électroniques peuvent, pour ce faire, comprendre des détecteurs ou des capteurs de position, de couple ou de temps de parcours.The various movements of the screen are preferably carried out in a motorized manner. An actuator is usually placed in the winding tube and responds to commands from a user through a control interface such as a remote control or a wall interface. The actuator comprises a motor and a reducer as well as an electronic control unit comprising electrical or electronic means for managing the movement of the screen as a function of the orders received and as a function of detected events. These electrical or electronic means can, to do this, comprise detectors or sensors of position, torque or travel time.

Le réglage de ces positions particulières n'est généralement pas facile, même si de plus en plus, celui-ci peut être réalisé partiellement automatiquement. Dans un mode de réglage, l'installateur lance généralement une procédure de réglage de cette position intermédiaire, en pilotant éventuellement manuellement les déplacements nécessaires pour atteindre ces positions ou en provoquant manuellement l'enregistrement de certaines positions atteintes par la lame inférieure du tablier.The adjustment of these particular positions is generally not easy, although more and more, this can be done partially automatically. In an adjustment mode, the installer generally initiates a procedure for adjusting this intermediate position, possibly manually controlling the movements necessary to reach these positions or by manually causing the recording of certain positions reached by the lower blade of the apron.

Au cours de la procédure de réglage, l'installateur doit procéder à une pluralité de réglages, qui diffèrent selon les installations. Ces réglages sont expliqués sur des notices et les ergonomies nécessaires pour réaliser chaque opération doivent être minutieusement reproduits. Ainsi, un risque d'erreur existe. Il existe donc un besoin de conception d'installations d'écran motorisé dont le réglage et la mise en service ne nécessitent plus ou peu d'intervention humaine, ou en tous cas une intervention la plus aisée possible.During the adjustment procedure, the installer must make a number of adjustments, which differ according to the installations. These settings are explained in the instructions and the ergonomics required to perform each operation must be carefully reproduced. Thus, a risk of error exists. So there is a need to design motorized screen installations whose adjustment and commissioning require little or no human intervention, or in any case the easiest possible intervention.

L'invention a pour but de remédier à ces inconvénients en proposant un procédé de commande d'une installation d'écran motorisé comprenant un écran enroulable sur un tube d'enroulement et un actionneur de manœuvre du tube d'enroulement, ledit actionneur comprenant une unité électronique de commande, le procédé comprenant une étape d'activation, par un utilisateur, d'un élément de commande de déplacement de l'écran motorisé jusqu'à une position cible prédéterminée,
caractérisé en ce qu'il comprend, après l'étape d'activation et grâce à l'unité électronique de commande, une étape de vérification de la mise en mémoire de la position cible prédéterminée, puis :

  1. a) si la mise en mémoire de la position cible a été préalablement effectuée, une étape de déplacement de l'écran motorisé vers la position cible, et
  2. b) si la mise en mémoire de la position cible n'a pas été préalablement effectuée, la séquence suivante d'étapes est effectuée :
    • détermination d'au moins un prérequis de paramétrage par une séquence préétablie de déplacements d'une l'extrémité libre (5) de l'écran ou d'activations de l'actionneur de l'écran motorisé, et
    • détermination de la position cible à l'aide des prérequis de paramétrage ainsi obtenus.
The object of the invention is to remedy these drawbacks by proposing a method for controlling a motorized screen installation comprising a screen which can be rolled up onto a winding tube and an actuator for operating the winding tube, said actuator comprising a winding tube. electronic control unit, the method comprising a step of activating, by a user, an element for controlling movement of the motorized screen to a predetermined target position,
characterized in that it comprises, after the activation step and thanks to the electronic control unit, a step of verifying the storage of the predetermined target position, then:
  1. a) if the target position has been stored beforehand, a step of moving the motorized screen to the target position, and
  2. b) if the target position has not been previously stored, the following sequence of steps is performed:
    • determination of at least one parameterization prerequisite by a pre-established sequence of movements of a free end (5) of the screen or of activations of the actuator of the motorized screen, and
    • determination of the target position using the configuration prerequisites thus obtained.

Grâce à l'étape de vérification de la mise en mémoire de la position cible déterminée et à la détermination de la positon cible à l'aide de prérequis de paramétrage lorsque cette dernière n'a pas été préalablement enregistrée, l'installation d'écran motorisé pourra, de façon automatique, sans intervention de l'utilisateur autre que l'activation de l'élément de commande de déplacement de l'extrémité libre de l'écran, soit déterminer la position cible, soit y déplacer l'extrémité libre de l'écran.Thanks to the step of verifying the storage of the determined target position and the determination of the target position using the prerequisites for parameterization when the latter has not been previously recorded, the screen installation motor vehicle can, automatically, without user intervention other than the activation of the control element for moving the free end of the screen, either determine the target position or move the free end of it there. the screen.

Ainsi, lors d'une première utilisation de l'écran motorisé, par exemple lors de son installation, l'utilisateur déclenchera le procédé de réglage par activation de l'élément de commande, ce qui permettra la détermination automatique de la position cible avant le déplacement par apprentissage via l'acquisition de prérequis de paramétrage. Puis, lors d'utilisations ultérieures, l'activation de l'élément de commande permettra le déplacement de l'extrémité libre de l'écran vers la position cible. De ce fait, l'activation d'un seul et même élément de commande permet le réglage de l'écran et le déplacement de son extrémité libre vers la position cible, ce qui simplifie grandement les manipulations à mettre en œuvre par l'utilisateur, qui active le même élément de commande que l'installation d'écran motorisé soit déjà réglée ou non. Par activation d'un élément de commande ou par activation d'un élément de commande de déplacement de l'extrémité libre de l'écran motorisé jusqu'à une position cible prédéterminée, on entend une activation particulière, par un utilisateur, d'un moyens physique, l'effet de l'activation particulière étant le déplacement du tablier vers la position cible lorsque celle-ci est connue et en mémoire de l'actionneur. Ainsi, l'activation d'un seul et même élément de commande équivaut à une même activation particulière, par un utilisateur, d'un moyen physique.Thus, during a first use of the motorized screen, for example during its installation, the user will trigger the adjustment process by activating the control element, which will allow the automatic determination of the target position before movement by learning via the acquisition of parameter setting prerequisites. Then, during subsequent uses, the activation of the control element will allow the displacement of the free end of the screen towards the target position. As a result, the activation of one and the same control element allows the adjustment of the screen and the displacement of its free end towards the target position, which greatly simplifies the operations to be carried out by the user, which activates the same control element whether or not the motorized screen installation is already set. By activation of a control element or by activation of a control element for moving the free end of the motorized screen to a predetermined target position, is meant a particular activation, by a user, of a physical means, the effect of the particular activation being the displacement of the apron towards the target position when this is known and in the memory of the actuator. Thus, the activation of one and the same control element is equivalent to the same particular activation, by a user, of a physical means.

De préférence, ledit au moins un prérequis de paramétrage est le sens de rotation de l'actionneur.Preferably, said at least one parameterization prerequisite is the direction of rotation of the actuator.

De préférence, ledit au moins un prérequis de paramétrage est une position extrême de l'extrémité libre de l'écran motorisé dans le sens de déroulement de l'écran.Preferably, said at least one parameterization prerequisite is an extreme position of the free end of the motorized screen in the direction of unwinding of the screen.

Selon un mode de réalisation particulier de l'invention, le procédé comprend en outre une étape de mise en mémoire de la position cible.According to a particular embodiment of the invention, the method further comprises a step of storing the target position.

Selon un mode de réalisation particulier de l'invention, le procédé comprend une étape de déplacement de l'extrémité libre de l'écran ou d'activations de l'actionneur de l'écran motorisé comprenant une succession de mouvements dans des sens différents.According to a particular embodiment of the invention, the method comprises a step of moving the free end of the screen or activating the actuator of the motorized screen comprising a succession of movements in different directions.

Selon un mode de réalisation particulier de l'invention, l'écran comprenant un tablier muni d'une une pluralité de lames orientables et l'installation comprenant un mécanisme de basculement de l'orientation des lames, la position cible est une position dite d'orientation, un basculement de l'orientation des lames orientables étant activé dans un deuxième sens, notamment le sens de l'enroulement, si l'extrémité libre du tablier atteint préalablement au moins une position d'entrée dans le mécanisme de basculement lors d'un déplacement dans un premier sens.According to a particular embodiment of the invention, the screen comprising an apron provided with a plurality of orientable slats and the installation comprising a mechanism for tilting the orientation of the slats, the target position is a so-called d position. 'orientation, a tilting of the orientation of the orientable slats being activated in a second direction, in particular the direction of winding, if the free end of the apron previously reaches at least one entry position in the tilting mechanism during a movement in a first direction.

Selon un mode de réalisation particulier de l'invention, l'écran comprenant un tablier apte à être déployé dans un plan sécant à son plan d'enroulement et l'installation comprenant un mécanisme de projection du tablier de manière à le déployer dans un plan sécant à un plan de déroulement principal, la position cible est une position dite de projection, la projection du tablier étant activée dans un deuxième sens, notamment le sens de l'enroulement, si l'extrémité libre du tablier atteint préalablement au moins une position d'entrée dans le mécanisme de projection lors d'un déplacement dans un premier sens.According to a particular embodiment of the invention, the screen comprising an apron capable of being deployed in a plane secant to its winding plane and the installation comprising a mechanism for projecting the apron so as to deploy it in a plane. secant to a main unwinding plane, the target position is a so-called projection position, the projection of the apron being activated in a second direction, in particular the direction of winding, if the free end of the apron previously reaches at least one position entry into the projection mechanism when moving in a first direction.

Selon un mode de réalisation particulier de l'invention, l'installation comprenant des moyens de verrouillage de l'extrémité libre de l'écran, la position cible est une position dite verrouillée dans un deuxième sens de déplacement, notamment le sens de l'enroulement, le verrouillage étant activé dans le deuxième sens si l'extrémité libre du tablier atteint préalablement au moins une position d'entrée dans les moyens de verrouillage, située au-delà de la position verrouillée dans un premier sens, notamment le sens du déroulement du tablier.According to a particular embodiment of the invention, the installation comprising means for locking the free end of the screen, the target position is a so-called locked position in a second direction of movement, in particular the direction of movement. winding, the locking being activated in the second direction if the free end of the apron previously reaches at least one entry position in the locking means, located beyond the locked position in a first direction, in particular the direction of unwinding apron.

Selon un mode de réalisation préféré de l'invention rendant simple la détermination de la position d'entrée dans le mécanisme de basculement, le mécanisme de projection ou les moyens de verrouillage, la position d'entrée dans le mécanisme de basculement, le mécanisme de projection ou les moyens de verrouillage est obtenue par l'intermédiaire d'une position de référence, la position de référence étant associée à la détection d'une valeur maximum d'un paramètre lié au mouvement de l'écran motorisé.According to a preferred embodiment of the invention making it simple to determine the entry position in the tilting mechanism, the projection mechanism or the locking means, the entry position in the tilting mechanism, the locking mechanism. projection or the locking means is obtained by means of a reference position, the reference position being associated with the detection of a maximum value of a parameter linked to the movement of the motorized screen.

De préférence, la position d'entrée dans le mécanisme de basculement, le mécanisme de projection ou les moyens de verrouillage est obtenue par un décalage d'une valeur prédéterminée à partir de la position de référence. Ce décalage peut notamment être lié à des considérations géométriques du mécanisme de blocage ou de sa localisation dans l'installation.Preferably, the entry position in the tilting mechanism, the projection mechanism or the locking means is obtained by an offset of a predetermined value from the reference position. This offset may in particular be linked to geometric considerations of the locking mechanism or of its location in the installation.

Ainsi, dans la plupart des installations, lorsque le mécanisme de blocage est situé à proximité de la position de référence, la position d'entrée du mécanisme de blocage pourra être définie à partir de la position de référence repérée automatiquement.Thus, in most installations, when the locking mechanism is located close to the reference position, the entry position of the locking mechanism can be defined from the automatically marked reference position.

Selon un mode de réalisation préféré de l'invention, l'étape de vérification de la mise en mémoire de la position cible prédéterminée, de détermination d'au moins un prérequis de paramétrage et de détermination de la position cible à l'aide des prérequis de paramétrage ainsi obtenus sont mises en œuvre par l'actionneur.According to a preferred embodiment of the invention, the step of verifying the storage of the predetermined target position, of determining at least one parameterization prerequisite and of determining the target position using the prerequisites parameters thus obtained are implemented by the actuator.

De préférence, afin d'obtenir une ergonomie particulièrement simple pour l'utilisateur, l'élément de commande de déplacement de l'extrémité libre de l'écran motorisé est une touche spécifique d'une télécommande de déplacement de l'extrémité libre de l'écran motorisé. Cette touche spécifique est différente de touches de la télécommande permettant d'activer des déplacements du tablier vers l'une ou l'autres des positions extrêmes.Preferably, in order to obtain particularly simple ergonomics for the user, the control element for moving the free end of the motorized screen is a specific button on a remote control for moving the free end of the screen. motorized screen. This specific key is different from the remote control keys enabling movement of the apron to one or other of the extreme positions.

Une installation d'écran motorisé 1 est représentée à la figure 1. Cette installation comprend un tablier 2, par exemple un tablier de volet roulant composé d'une pluralité de lames articulées 3. De préférence, le tablier 2 est constitué de lames 3 empilables, les lames 3 étant reliées entre elles par des parties ajourées escamotables dès que les lames 3 reposent les unes sur les autres. Le tablier 2 est lié, à une de ses extrémités, dite extrémité supérieure, à un tube d'enroulement 4. A l'autre extrémité libre du tablier 2, dite extrémité inférieure, une lame inférieure 5 est guidée par des rails de guidage disposés de part et d'autre d'une ouverture dans un bâtiment, le tablier 2 étant destiné à recouvrir l'ouverture lorsqu'il est fermé. Le tube d'enroulement 4 est de préférence monté au-dessus de l'ouverture que le tablier 2 est destiné à recouvrir. Le tablier 2 vient de préférence s'enrouler dans un caisson 6 destiné à le protéger.A motorized screen installation 1 is shown in figure 1 . This installation comprises an apron 2, for example a roller shutter apron composed of a plurality of articulated slats 3. Preferably, the apron 2 consists of stackable slats 3, the slats 3 being interconnected by retractable openwork parts as soon as possible. that the blades 3 rest on each other. The apron 2 is linked, at one of its ends, called the upper end, to a winding tube 4. At the other free end of the apron 2, called the lower end, a lower blade 5 is guided by guide rails arranged on either side of an opening in a building, the apron 2 being intended to cover the opening when it is closed. The winding tube 4 is preferably mounted above the opening that the apron 2 is intended to cover. The apron 2 is preferably rolled up in a box 6 intended to protect it.

L'écran motorisé 1 peut notamment consister en un élément de fermeture, d'occultation ou de protection solaire. Dans l'exemple représenté sur les figures, il s'agit d'un tablier 2 composé de lames articulées 3, mais il pourrait également s'agir d'une toile. Dans ce cas, la lame inférieure 5 est remplacée par une barre de charge. De préférence, le tablier 2 comporte un ensemble de lames empilables reliées les unes aux autres par des parties escamotables et ajourées.The motorized screen 1 may in particular consist of a closing, concealment or sun protection element. In the example shown in the figures, it is an apron 2 composed of articulated blades 3, but it could also be a canvas. In this case, the lower blade 5 is replaced by a load bar. Preferably, the apron 2 comprises a set of stackable slats connected to each other by retractable and perforated parts.

Les déplacements du tablier 2 sont commandés par les déplacements de rotation du tube d'enroulement 4, dont l'entraînement est assuré par exemple à l'aide d'un actionneur comprenant par exemple un ensemble motoréducteur tubulaire (non représenté) disposé à l'intérieur du tube d'enroulement 4. L'ensemble motoréducteur comprend notamment un moteur électrique et un réducteur, en particulier un réducteur épicycloïdal. Le moteur électrique peut être de type à courant continu et à balais et collecteur, à courant continu et à commutation électronique (Brushless Direct Current motor en langue anglaise) ou asynchrone. Le moteur est piloté par une unité électronique de commande 7, celle-ci étant également reliée à une interface utilisateur 8 par le biais de laquelle un utilisateur peut commander les mouvements du tablier 2. L'interface utilisateur 8 peut être reliée à l'unité de commande 7 par des moyens de communication filaire ou non filaire tels que des ondes radioélectriques ou des rayons infrarouges. L'interface utilisateur 8 est par exemple munie de deux touches qui permettent à un utilisateur de commander respectivement un déplacement de l'écran motorisé 1 vers le haut (enroulement) ou vers le bas (déroulement). Une combinaison de touches permet également de déplacer l'écran motorisé 1 vers une position cible, définie plus loin. Dans une variante, l'interface utilisateur comprend une touche spécifique dont l'activation permet le déplacement de l'écran motorisé 1 dans la position cible. L'interface utilisateur 8 est par exemple une télécommande portative.The movements of the apron 2 are controlled by the rotational movements of the winding tube 4, the drive of which is ensured for example by means of an actuator comprising for example a tubular geared motor assembly (not shown) arranged at the inside the winding tube 4. The geared motor assembly comprises in particular an electric motor and a reduction gear, in particular an epicyclic reduction gear. The electric motor can be of direct current and brush and collector type, direct current and electronically commutated (Brushless Direct Current motor) or asynchronous. The motor is driven by a unit control electronics 7, the latter also being connected to a user interface 8 by means of which a user can control the movements of the apron 2. The user interface 8 can be connected to the control unit 7 by means of wired or wireless communication such as radio waves or infrared rays. The user interface 8 is for example provided with two keys which allow a user to respectively control a movement of the motorized screen 1 upward (winding) or downward (unwinding). A combination of keys also makes it possible to move the motorized screen 1 to a target position, defined below. In a variant, the user interface comprises a specific key whose activation allows the movement of the motorized screen 1 in the target position. The user interface 8 is for example a portable remote control.

L'unité électronique de commande 7 comprend un ou plusieurs moyens de détection 9 de la variation d'un paramètre lié au mouvement de l'écran motorisé 1. Dans le mode de réalisation illustré ici, l'unité de commande comprend un détecteur ou capteur 10 de position angulaire du tube d'enroulement 4, et un détecteur ou capteur de couple 12 exercé par l'actionneur pour détecter des obstacles et/ou les fins de course. Par détecteur ou capteur de position ou de couple, on entend tout moyen matériel et/ou logiciel de détermination de la position ou du couple. L'unité de commande 7 comprend notamment une unité logique de traitement 14 et une mémoire 16.The electronic control unit 7 comprises one or more means 9 for detecting the variation of a parameter linked to the movement of the motorized screen 1. In the embodiment illustrated here, the control unit comprises a detector or sensor. 10 for the angular position of the winding tube 4, and a torque detector or sensor 12 exerted by the actuator to detect obstacles and / or limit switches. The term “position or torque detector or sensor” means any hardware and / or software means for determining the position or the torque. The control unit 7 comprises in particular a logic processing unit 14 and a memory 16.

Le long des rails de guidage disposés de part et d'autre de l'ouverture, l'installation 1 comprend un mécanisme de blocage, par exemple des moyens de verrouillage 18. Ces moyens de verrouillage 18 peuvent être logés à l'intérieur des rails de guidage et comprennent notamment deux ensembles similaires de part et d'autre du tablier 2 de l'écran motorisé 1. Les moyens de verrouillage 18 coopèrent avec les extrémités de la lame inférieure 5, en particulier avec des ergots fixés élastiquement aux extrémités de la lame finale (non représentés). Ces moyens de verrouillage 18 déterminent une position d'entrée dans les moyens verrouillage PEV, telle que lorsque la lame inférieure 5 dépasse cette position dans le sens du déroulement de l'écran 1, la lame inférieure 5 est bloquée dans les moyens de verrouillage 18 lors d'un mouvement de montée. Un mouvement de descente au-delà d'une position de sortie des moyens de verrouillage 18 est nécessaire pour que la lame inférieure 5 puisse remonter au-delà de la position d'entrée PEV. Le fonctionnement de tels moyens de verrouillage 8, connus de l'art antérieur, est notamment décrit, en référence à la figure 3, dans le deuxième mode de réalisation de la demande de brevet FR 3 009 577 .Along the guide rails arranged on either side of the opening, the installation 1 comprises a locking mechanism, for example locking means 18. These locking means 18 can be housed inside the rails. guide and include in particular two similar assemblies on either side of the apron 2 of the motorized screen 1. The locking means 18 cooperate with the ends of the lower blade 5, in particular with lugs elastically fixed to the ends of the final blade (not shown). These locking means 18 determine an entry position in the PEV locking means, such that when the lower blade 5 exceeds this position in the direction of the unwinding of the screen 1, the lower blade 5 is blocked in the locking means 18 during an upward movement. A movement of descent beyond an exit position of the locking means 18 is necessary so that the lower blade 5 can rise beyond the entry position PEV. The operation of such locking means 8, known from the prior art, is described in particular, with reference to the figure 3 , in the second embodiment of the patent application FR 3 009 577 .

On notera que dans ce qui suit, on considère que le tablier 2 se déroule vers le bas, notamment sous l'effet de son propre poids. Dans le cas d'un store, il se déroule sous l'effet du poids de sa barre de charge. D'autres configurations sont toutefois évidemment possibles.It will be noted that in what follows, it is considered that the apron 2 unwinds downwards, in particular under the effect of its own weight. In the case of a blind, it unrolls under the effect of the weight of its load bar. Other configurations are however obviously possible.

On a représenté aux figures 2 et 3 deux autres installations d'écran motorisé 1 nécessitant la détermination de positions cibles pouvant être commandée par le procédé de commande selon l'invention.We represented at figures 2 and 3 two other motorized screen installations 1 requiring the determination of target positions which can be controlled by the control method according to the invention.

La figure 2 illustre en coupe droite une baie vitrée 20 équipée d'une installation d'écran motorisé 1. Une telle installation est notamment connue du document FR2962759 . Elle comporte un tube d'enroulement 4 logé à l'intérieur d'un caisson 6 et autour duquel est apte à venir s'enrouler un tablier 2 constitué de lames 3 articulées entre elles, dont une lame inférieure 5. L'installation d'écran motorisé 1 comprend de plus deux coulisses latérales 26, 28 solidaires du caisson 6 disposées en regard l'une de l'autre, dans lesquelles les deux bordures latérales opposées 30, 32 du tablier 2 sont engagées et peuvent coulisser. Le caisson 6 est monté pivotant autour du tube d'enroulement 4 avec les coulisses latérales 26, 28. La baie 20 présente deux montants latéraux opposés 34, 36 équipés respectivement d'un vérin à gaz 38, 40 reliant les coulisses latérales 26, 28 au moyen d'une chape 42, 44. Par ce biais, les coulisses latérales 26, 28 et le tablier 2 qui s'étend entre elles, peuvent être disposés dans une position de basculement écartée des montants latéraux 34, 36. Les montants latéraux 34, 36 sont équipés respectivement d'un mécanisme de projection comprenant un verrou 46, 48, permettant de maintenir les coulisses latérales 26, 28 contre leur montant latéral respectif 34, 36 et donc le tablier 2 dans une position de projection PJ dans laquelle il est déployé dans un plan sécant au plan de son enroulement 2. La figure 2 illustre l'écran motorisé 1 en position de projection PJ. Cette position de projection PJ peut être atteinte à partir du moment où l'extrémité libre 5 du tablier 2 a atteint une position de blocage P2 dans le mécanisme de blocage, ici par le biais des vérins 38, 40, ou, dans d'autres modes de réalisation, par traction sur des bras. Une position P3 d'entrée dans le mécanisme de blocage constitué par le verrou 46, 48 peut également être déterminée par le procédé selon l'invention.The figure 2 illustrates in straight section a bay window 20 equipped with a motorized screen installation 1. Such an installation is in particular known from the document FR2962759 . It comprises a winding tube 4 housed inside a box 6 and around which is suitable for winding an apron 2 consisting of blades 3 articulated together, including a lower blade 5. The installation of motorized screen 1 further comprises two lateral slides 26, 28 integral with the box 6 arranged opposite one another, in which the two opposite lateral edges 30, 32 of the apron 2 are engaged and can slide. The box 6 is mounted to pivot around the winding tube 4 with the side slides 26, 28. The bay 20 has two opposite side uprights 34, 36 respectively equipped with a gas spring 38, 40 connecting the side slides 26, 28 by means of a yoke 42, 44. By this means, the lateral slides 26, 28 and the apron 2 which extends between them, can be arranged in a tilting position separated from the lateral uprights 34, 36. The lateral uprights 34, 36 are respectively equipped with a projection mechanism comprising a lock 46, 48, making it possible to hold the side slides 26, 28 against their respective lateral upright 34, 36 and therefore the apron 2 in a projection position PJ in which it is deployed in a plane secant to the plane of its winding 2. The figure 2 illustrates the motorized screen 1 in the projection position PJ. This projection position PJ can be reached from the moment when the free end 5 of the apron 2 has reached a locking position P2 in the locking mechanism, here by means of the jacks 38, 40, or, in other embodiments, by pulling on the arms. An entry position P3 in the locking mechanism constituted by the latch 46, 48 can also be determined by the method according to the invention.

La figure 3 illustre schématiquement une installation d'écran motorisé 1, comprenant un tablier 2 muni d'une pluralité de lames orientables 3 liées entre elles. Une telle installation est notamment connue du document EP2226462 . L'extrémité libre 5 du tablier 2 comporte, sur chacune des deux extrémités, dont une seule est représentée, un ergot 50 prévu pour coopérer avec un mécanisme de basculement 52 disposé le long de la glissière 54 correspondante. Le passage de la lame inférieure 5 dans le mécanisme de basculement 52 définit, de manière similaire aux moyens de verrouillage décrits plus hauts, une position d'entrée P3 dans le mécanisme de basculement 52. Pour provoquer le basculement des lames 3 du tablier 2, il est nécessaire que la lame finale 5 atteigne la position d'entrée P3 du mécanisme de basculement 52, lors d'un déroulement du tablier 2. Une inversion de sens vient ensuite bloquer l'ergot 50 dans la position de blocage P2. La poursuite du mouvement d'enroulement permet l'extension du tablier 2 et le basculement en ouverture des lames 3. La lame inférieure 5 est alors dans une position d'orientation PO des lames orientables 3. Pour enrouler de nouveau le tablier 2, un mouvement de déroulement permet le basculement des lames 3 en fermeture, puis le déplacement de la lame inférieure 5 au-delà de la position de sortie du mécanisme de basculement P4. Le tablier 2 peut ensuite être complètement enroulé.The figure 3 schematically illustrates a motorized screen installation 1, comprising an apron 2 provided with a plurality of orientable slats 3 linked together. Such an installation is in particular known from the document EP2226462 . The free end 5 of the apron 2 comprises, on each of the two ends, only one of which is shown, a lug 50 provided to cooperate with a tilting mechanism 52 disposed along the corresponding slide 54. The passage of the lower blade 5 in the tilting mechanism 52 defines, in a manner similar to the locking means described above, an entry position P3 in the tilting mechanism 52. To cause the tilting of the blades 3 of the apron 2, it is necessary for the final blade 5 to reach the input position P3 of the tilting mechanism 52, during an unwinding of the apron 2. A reversal of direction then locks the lug 50 in the locking position P2. The continuation of the winding movement allows the extension of the apron 2 and the opening tilting of the slats 3. The lower slat 5 is then in a position of orientation PO of the orientable slats 3. To wind the apron 2 again, unwinding movement allows the tilting of the blades 3 in closing, then the displacement of the lower blade 5 beyond the output position of the tilting mechanism P4. The apron 2 can then be completely rolled up.

On va maintenant décrire le procédé de commande selon l'invention en référence à la figure 4.The control method according to the invention will now be described with reference to the figure 4 .

Au cours d'une première étape d'activation 100, un utilisateur active un élément de commande de déplacement de l'extrémité libre de l'écran motorisé 1 jusqu'à une position cible prédéterminée. La position cible peut être une position de blocage dans un mécanisme de blocage, telle que la position verrouillée PV, la position de projection PJ ou la position d'orientation PO, selon le type d'installation d'écran motorisé 1. L'élément de commande est ici une touche de l'interface utilisateur 8 de déplacement de la lame inférieure 5.During a first activation step 100, a user activates a control element for moving the free end of the motorized screen 1 to a predetermined target position. The target position can be a locking position in a locking mechanism, such as the PV locked position, the PJ projection position or the PO orientation position, depending on the type of motorized screen installation 1. The element command is here a user interface button 8 for moving the lower blade 5.

Après activation par l'utilisateur, une étape de vérification 102 s'enclenche, durant laquelle l'on vérifie que la position cible a été enregistrée ou non dans la mémoire 16 de l'unité de commande 7. Si la mise en mémoire de la position cible PV, PJ ou PO a été préalablement effectuée, une étape de déplacement 104 de l'extrémité libre de l'écran motorisé vers la position cible PV, PJ, PO est effectuée.After activation by the user, a verification step 102 is triggered, during which it is verified whether the target position has been recorded or not in the memory 16 of the control unit 7. If the storage of the target position PV, PJ or PO has been performed beforehand, a step 104 of moving the free end of the motorized screen towards the target position PV, PJ, PO is performed.

Dans le cas contraire, si la mise en mémoire de la position cible n'a pas été préalablement effectuée, on détermine au moins un prérequis de paramétrage par une séquence préétablie de déplacements de l'extrémité libre 5 du tablier 2 ou d'activations de l'actionneur de l'écran motorisé 1. La détermination de ce ou ces prérequis de paramétrage permettra la détermination de la position cible PV, PJ ou PO comme le verra plus loin.Otherwise, if the target position has not been previously stored in memory, at least one parameterization prerequisite is determined by a pre-established sequence of movements of the free end 5 of the apron 2 or of activations of the motorized screen actuator 1. Determining this or these parameter setting prerequisites will allow the determination of the target position PV, PJ or PO as will be seen later.

Dans le mode de réalisation préféré de l'invention illustré à la figure 4, au moins un des prérequis de paramétrage est le sens de rotation de l'actionneur.In the preferred embodiment of the invention illustrated in figure 4 , at least one of the parameter setting prerequisites is the direction of rotation of the actuator.

Ainsi, au cours d'une étape 106, l'on vérifie que le sens de rotation de l'actionneur est déjà connu (mis en mémoire dans la mémoire 16 de l'unité de commande 7). Si tel n'est pas le cas, au cours d'une étape 108, on met en œuvre une séquence de mouvements, comprenant par exemple une succession de mouvements dans des sens différents, tout en surveillant des paramètres de l'actionneur, tel que le courant ou la tension. Cette étape 108 permet, de façon connue de l'art antérieur avec diverses méthodes, de déterminer automatiquement le sens de rotation de l'actionneur.Thus, during a step 106, it is verified that the direction of rotation of the actuator is already known (stored in the memory 16 of the control unit 7). If this is not the case, during a step 108, a sequence of movements is implemented, comprising for example a succession of movements in different directions, while monitoring parameters of the actuator, such as current or voltage. This step 108 makes it possible, in a manner known from the prior art with various methods, to automatically determine the direction of rotation of the actuator.

Une fois l'étape 108 réalisée ou si le sens de rotation de l'actionneur était préalablement enregistré dans la mémoire 16, l'on vérifie, lors d'une étape 110, si une position extrême inférieure FDCB est connue, c'est-à-dire si elle a été préalablement enregistrée dans la mémoire 16. Si tel n'est pas le cas, au cours d'une étape 112, un ou plusieurs mouvements dans le sens du déroulement sont effectués. Cette étape 112 permet, de façon connue de l'art antérieur, de déterminer la position extrême inférieure FDCB de l'écran 1.Once step 108 has been carried out or if the direction of rotation of the actuator was previously recorded in memory 16, it is checked, during a step 110, whether a lower extreme position FDCB is known, that is that is, if it has been previously recorded in the memory 16. If this is not the case, during a step 112, one or more movements in the direction of unwinding are carried out. This step 112 makes it possible, in a manner known from the prior art, to determine the extreme lower position FDCB of the screen 1.

Une fois l'étape 112 réalisée ou si la position extrême inférieure FDCB était préalablement enregistrée dans la mémoire 16, l'on détermine, au cours d'une étape 114, une position de référence permettant de déterminer la position cible. On notera ici que l'étape 114 est optionnelle, la position cible pouvant dans certains cas être déterminée sans passer par la détermination d'une position de référence intermédiaire.Once step 112 has been performed or if the lower extreme position FDCB was previously recorded in memory 16, a reference position is determined during a step 114, making it possible to determine the target position. It will be noted here that step 114 is optional, the target position being able in certain cases to be determined without going through the determination of an intermediate reference position.

Dans le cas de la recherche d'une position cible telle que la position de blocage dans un mécanisme de blocage, par exemple la position de verrouillage PV, l'étape 114 est effectuée. En particulier, cette étape permet de déterminer une position de référence PMB, par exemple correspondant au décollement de la lame inférieure 5 du tablier 2 d'une position en contact avec un seuil de l'ouverture, lors d'un mouvement d'enroulement du tablier 2.In the case of searching for a target position such as the locking position in a locking mechanism, for example the PV locking position, step 114 is performed. In particular, this step makes it possible to determine a reference position PMB, for example corresponding to the separation of the lower blade 5 of the apron 2 from a position in contact with a threshold of the opening, during a winding movement of the apron 2.

Cette position PMB est associée à la détection d'une valeur maximum d'un paramètre lié au mouvement de l'écran motorisé 1. Le paramètre est de préférence le couple exercé par l'actionneur entraînant en mouvement l'écran motorisé 1 au cours d'un mouvement de montée. Ce couple est par exemple déterminé à partir d'une mesure du courant traversant un moteur électrique de l'actionneur.This PMB position is associated with the detection of a maximum value of a parameter linked to the movement of the motorized screen 1. The parameter is preferably the torque exerted by the actuator driving the motorized screen 1 in motion during 'an upward movement. This torque is for example determined from a measurement of the current flowing through an electric motor of the actuator.

La position dans laquelle la lame inférieure 5 est décollée du seuil du volet peut être repérée de manière fiable par la détermination d'un maximum local de couple, au voisinage du mécanisme de blocage.The position in which the lower blade 5 is detached from the threshold of the shutter can be reliably identified by determining a local maximum of torque, in the vicinity of the locking mechanism.

L'obtention de cette position de décollement, ou position de référence PMB, permet de déterminer la position d'entrée dans les moyens de verrouillage PEV par un décalage d'une valeur prédéterminée à partir de la position de référence PMB. En effet, la position d'entrée dans les moyens de verrouillage PEV et la position de décollement PMB sont espacées par une distance prédéterminée, qui dépend des caractéristiques de l'installation et notamment du mécanisme de blocage et de sa localisation par rapport aux rails de guidage de l'installation. La position d'entrée P3 dans le mécanisme de projection ou les positions d'entrée P3 dans le mécanisme de basculement peuvent être déterminée de manière analogue via la connaissance de la position de décollement PMB.Obtaining this detachment position, or reference position PMB, makes it possible to determine the entry position in the locking means PEV by an offset by a predetermined value from the reference position PMB. Indeed, the entry position in the PEV locking means and the PMB detachment position are spaced by a predetermined distance, which depends on the characteristics of the installation and in particular on the locking mechanism and its location relative to the rails. installation guidance. The entry position P3 in the throwing mechanism or the entry positions P3 in the tilting mechanism can be determined analogously through the knowledge of the peel position PMB.

A partir de la détermination position d'entrée dans les moyens de verrouillage PEV, la position de verrouillage PV peut être obtenue par diverses manières connues en soi, par exemple par un procédé d'apprentissage tel que celui décrit dans EP 1 650 625 . La position de projection PJ ou d'orientation PO peut être déterminée de manière analogue via la connaissance, respectivement, de la position P3 d'entrée dans le mécanisme de projection ou de la position d'entrée P3 dans le mécanisme de basculement.From the determination of the entry position in the PEV locking means, the PV locking position can be obtained by various ways known per se, for example by a learning method such as that described in EP 1,650,625 . The projection position PJ or orientation PO can be determined analogously through the knowledge, respectively, of the entry position P3 in the projection mechanism or the entry position P3 in the tilting mechanism.

Ainsi, au cours d'une étape 116, la position cible est déterminée à l'aide des prérequis de paramétrage obtenus au cours des étapes 106 et 110, et éventuellement à l'aide de la position de référence PMB.Thus, during a step 116, the target position is determined using the parameterization prerequisites obtained during steps 106 and 110, and possibly using the reference position PMB.

Dans le mode de réalisation préféré de l'invention illustré à la figure 4, l'étape 102 de vérification de la mise en mémoire de la position cible prédéterminée, de détermination d'u ou des prérequis de paramétrage 106, 108 et de détermination de la position cible 116 à l'aide des prérequis de paramétrage ainsi obtenus sont mises en œuvre par l'actionneur.In the preferred embodiment of the invention illustrated in figure 4 , the step 102 of verifying the storage of the predetermined target position, of determining one or more parameterization prerequisites 106, 108 and of determining the target position 116 using the parameterization prerequisites thus obtained are implemented by the actuator.

Enfin, la position cible est mise en mémoire au terme de l'étape 116 de détermination de cette position cible et la lame inférieure 5 du tablier 2 est déplacée vers la position cible au cours de l'étape 104.Finally, the target position is stored at the end of step 116 for determining this target position and the lower blade 5 of the apron 2 is moved to the target position during step 104.

Naturellement, les exemples représentés sur les figures et discutés ci-dessus ne sont donnés qu'à titre illustratif et non limitatif. Diverses variantes sont envisageables. En particulier, la description donnée à titre d'exemple de moyens de verrouillage est tout à fait applicable également à d'autres types de mécanismes de blocage fonctionnant de manière similaire. En outre, la détermination et le déplacement vers d'autres position cibles que celles évoquées peuvent être effectuées à l'aide du procédé de commande selon l'invention. Les sens de déplacement pour atteindre ou quitter la position de blocage peuvent être adaptés en fonction des types de mécanismes de blocage.Of course, the examples shown in the figures and discussed above are given only by way of illustration and are not limiting. Various variants are possible. In particular, the description given by way of example of locking means is quite applicable also to other types of locking mechanisms operating in a similar manner. Furthermore, the determination and the displacement towards other target positions than those mentioned can be carried out using the control method according to the invention. The directions of movement to reach or leave the blocked position can be adapted depending on the types of blocking mechanisms.
