Definitions
- the invention relates to the field of installations of motorized rollable elements. It relates more particularly to an automated control method of an installation comprising a motorized screen, or motorized roller shutter, configured to be moved between a lower position and a higher position, the motorized screen comprising an apron provided with a free end or lower blade, the installation being provided with a locking mechanism or anchoring, cooperating with the lower blade, to block the movement thereof when moving to the upper position.
- the screen installations or known motorized rolling elements generally comprise a screen, such as an apron formed of articulated and stackable blades, or an assembly comprising a fabric and a weighted load bar, the apron 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 free end of the apron or load bar of the fabric 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 a box in which the screen is wound.
- These facilities may also include locking mechanisms, such as locking means for maintaining the lower blade or the load bar of the screen in a specific position while preventing it from being raised by breaking or slamming under the actions of the wind.
- locking mechanisms such as locking means for maintaining the lower blade or the load bar of the screen in a specific position while preventing it from being raised by breaking or slamming under the actions of the wind.
- Such installations are used in particular for shutters offering a secure ventilation position, the blades being spaced from each other and being separated from the threshold of the opening.
- Other locking mechanisms allow orientation of orientable blades of a shutter, as described in the application EP2226462 or else a projection of the deck in a plane secant to their main course plan, as described in the applications FR2962759 , EP2783063 or FR2941996 .
- the locking mechanisms of such installations are configured so that when moving the motorized screen in a first direction, for example during unwinding, the final blade of the screen, that is to say the blade the bottom of the hinged leaf shutter or the load bar of a fabric, enters the locking mechanism, then, following a reverse movement, in a second direction, locks in the locking mechanism.
- An actuator is generally placed in the winding tube and responds to commands from a user via a control interface such as a remote control or a wall interface.
- the actuator comprises a motor and a gearbox and an electronic control unit comprising electric or electronic means for managing the movement of the motorized screen according to the orders received and as a function of detected events.
- These electrical or electronic means may, for this purpose, include detectors or sensors position, torque or travel time.
- EP 1,650,625 a method of learning the positions of a locking device for automatically managing the maneuvers of a motorized screen according to orders received from the user.
- the learning process defines several positions.
- a first position corresponds to the upper limit of the motorized screen
- a second position corresponds to the so-called locking position
- a third position corresponds to the position in which the movement of the motorized screen must be reversed so as to activate the locking means
- a fourth position corresponds to the so-called unlocking position below which it is necessary to move to unlock the motorized screen.
- the installer proceeds to record the value of an angular position of the selected winding tube, called the recorded reversal position.
- This position is located, in the direction of unwinding of the motorized screen, at or beyond the third position (rotation reversal position).
- the user must place the blade bottom of the shutter or the load bar of the fabric in an area marked by markings on the guide rails or the locking means.
- an input position is automatically determined in the locking mechanism which can serve as an inversion position. of rotation candidate for the automatic learning of the position of inversion of rotation. This avoids the user having to place the lower blade of the shutter or the load bar of the fabric in an area marked by markings on the guide rails or the locking mechanism.
- the steps of analyzing the parameter variations and determining the input position are implemented by the actuator.
- the input position in the locking mechanism is obtained from the determination of a reference position, the reference position being associated with the detection of a local maximum value of the parameter or the detection of a maximum local variation value of the parameter.
- the adjustment process can be performed entirely automatically, without the intervention of an installer or a user to define the reference position associated with the locking mechanism.
- the input position in the locking mechanism is obtained by an offset of a predetermined value from the reference position.
- This offset may notably be related to geometric considerations of the locking mechanism or its location in the installation.
- the input position of the locking mechanism can be defined from the reference position automatically identified.
- the parameter is the torque exerted by the actuator causing the apron to move in the second direction of movement.
- Torque is indeed a parameter whose variations can be reliably and easily detected.
- the torque is determined from a measurement of the current flowing through an electric motor of the actuator.
- the recorded reversing position is sufficiently far from the stop position in the locking mechanism to prevent the bottom blade of the flap from being prematurely abutted in the locking mechanism while the actuator is in operation, the torque detection is not yet active or operational, and to prevent the actuator thus exerts significant effort on the locking mechanism that may damage it.
- the locking mechanism in fact comprises flexible or mobile fragile parts if they are subjected to significant mechanical forces and / or repeated.
- the installation position and / or the dimensions of the locking mechanism can be variable and the activation times of the torque detections can also differ from one actuator to another. It is therefore necessary to be able to refine the settings for each installation.
- each candidate rotational inversion position is stored in a memory of a control unit of the motorized screen installation.
- the distances between the candidate rotation reversing positions and the locked position are stored. These distances can be respectively associated with the locked position and these candidate rotation inversion positions. It is thus possible, from these stored data, to easily determine an optimal rotational inversion position.
- each candidate rotation inversion position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate inversion position.
- the interruption of the iteration of the sequence a) -b) is decided by detecting an absence of obstacle during the winding of the motorized screen at the level of the locked position or for a predetermined time from the starting of the winding.

- the locked position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the locked position.
- the angular position value of the winding tube corresponding to the output position is measured by means of an apron drive torque sensor.
- the output position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the output position.

- the Figure 3a illustrates in a straight section a bay window 20 equipped with a motorized screen installation 1.
- a motorized screen installation is notably known from FR2962759 . It comprises a winding tube 4 housed inside a box 6 and around which is adapted to come wind a deck 2 consisting of blades 3 hinged together, including a lower blade 5.

- the figure 3a illustrates the motorized screen 1 in the projected position.
- This projected position can be reached from the moment when the free end 5 of the deck 2 has reached a blocking position P2 in the lock 46, 48, here via the cylinders 38, 40, in other embodiments. by pulling on arms.
- An input position P3 in the locking mechanism constituted by the lock 46, 48 can also be determined by the method according to the invention.
- the figure 3'b schematically illustrates a motorized screen installation 1, comprising an apron 2 provided with a plurality of orientable blades 3 interconnected.
- a motorized screen installation comprising an apron 2 provided with a plurality of orientable blades 3 interconnected.
- the free end 5 of the deck 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, similarly to the mechanism of latch 18 mentioned above, an input position P3 in the tilting mechanism 52.
- To cause the blades of the deck 2 to tilt it is necessary for the final blade 5 to reach the input position P3 of the tilting mechanism 52, during unwinding of the apron 2.
- a reversal of direction then comes to block the lug 50 in a blocking position P2.
- the continuation of the winding movement allows the extension of the apron 2 and the tilting opening of the blades 3.
- a movement of unwinding allows the tilting of the blades 3 in closing, then the displacement of the blade lower 5 beyond an output position of the tilting mechanism P4.
- the apron 2 can then be completely wound.
- the setting method will be triggered by the actuation of an activation device from an activation element to be actuated by the user.
- the setting process will be triggered during the installation of the roller shutter for example, by pressing a combination of keys of the user interface 8, or by simply pressing a specific key.
- this combination of keys or the pressing of a particular key will trigger a first step 80 of analyzing the variations of a parameter related to the movement of the motorized screen 1 during the movement of the motorized screen 1.
- this analysis is performed by the actuator.
- the variations of the parameter make it possible in particular to identify particular positions of the lower blade 5 of the motorized screen 1.
- the parameter is preferably the torque exerted by the actuator causing the motorized screen 1 to move during a movement climb.
- This torque is for example determined from a measurement of the current flowing through an electric motor of the actuator. In the particular embodiment described here, this analysis is performed by the actuator, in particular by the electronic control unit 7 of the actuator.
- the torque variations observed during this movement of rise (or opening) of the motorized screen 1 are schematically represented as a function of the angular position of the winding tube 4 to the figure 7 . These variations correspond to variations in the weight of the apron suspended from the winding tube 4, as well as to variations related to the winding diameter, said winding diameter increasing over the opening due to the superposition of the windings of the blades. 2 on the winding tube 4.
- the position in which the lower blade 5 is detached from the threshold of the flap can be reliably identified by the determination of a local maximum torque, in the vicinity of the locking mechanism.
- This detachment position, or reference position PMB makes it possible to determine the entry position in the locking means P3 which are spaced by a predetermined distance, which depends on the characteristics of the flap.
- the reference position PMB is determined by detecting a maximum local value of the parameter or a maximum local variation value of the parameter. In the particular embodiment described here, this determination is made by the actuator and by comparison with a torque threshold.
- the input position is determined in the locking means P3. More particularly, the input position in the locking means P3 is obtained by shifting a predetermined value from the reference position PMB. This offset takes into account, in particular, the geometry and / or the dimensions of the locking mechanism, as well as the preferred mounting position of the latter in the installation, in particular at the bottom of the guide rails.
- the determination of the reference position PMB is done in particular during an upward movement or winding of the deck.
- the adjustment process can however, to be continued, in particular to refine this input position P3 in the locking mechanism.
- other movements are then implemented by the actuator, including a descent or unwinding movement, leading the lower blade 5 in the P3 position during a unwinding movement.
- the lower blade 5 is then in the locking means and in a so-called reversal area. In this reversal zone, an inversion of the direction of movement of the lower blade 5, from a downward movement to a rising movement, causes the lower blade 5 to lock in the locking means 18. This area, reversing the direction of movement of the lower blade 5 does not produce any particular effect.
- the lower blade 5 can in particular pass through the locking means 18 in the direction of the descent as in the direction of the climb without being locked if it does not occur reversal of its direction of movement between the positions P3 and P4.
- the position P3 determined at the end of the determination step 100 is chosen as the first candidate rotation reversal position PM1. It corresponds to an angular position DM1.
- the position P3 is stored in the memory 16 of the electronic control unit 7. Then, the lower blade 5 is moved in the unwinding direction to this position P3 thus recorded.
- apron 2 is then driven in the direction of winding to the locked position P2.
- a power supply of the geared motor is controlled causing the winding of the apron 2 and therefore the rise of the lower blade 5.
- the step 104 could also follow an action of the installer.
- the second position P2 is detected by the torque sensor 12, for example by detecting an overtorque, and supplying the geared motor is cut off.
- the angular position value D2 of the winding tube 4 corresponding to the position P2 of the lower blade is then recorded in memory in the control unit 7. It should be noted that the value of P2 recorded may correspond to a position slightly lower than the locking position of the lower blade 5, so that once in the mode of use, when a user controls the locking of the apron 2, the lower blade 5 does not come into abutment by exerting great efforts on the locking means 18.
- This sequence comprises at least two steps a) and b).
- step a) the apron 2 is driven in the unwinding direction to a second candidate rotational inversion position PM2 located beyond the first rotational inversion position PM1 in the direction of the unwinding of the apron 2.
- step b can also be recorded the distance or the time of movement between the positions PM1 and P2.
- the second candidate rotational inversion position is located at a predetermined distance d from the first candidate rotational inversion position.
- the second rotational reversing position PM2 is located at a predetermined distance d from the first candidate rotation reversing position PM1.
- the motorized screen installation 1 controls the unwinding of the apron 2 in a rotation allowing the lower blade 5 to reach, from the locking position P2, the position PM1-d in the unwinding direction.
- the distance d is advantageously chosen as a function of standard general dimensions of the locking means.
- each candidate rotation inversion position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate inversion position.
- the candidate rotation reversing position PM2 defined by the electronic control unit 7 is stored in memory 16 of the control unit 7.
- step b), or 110 as shown in the diagram of the figure 5 the apron 2 is again driven in the direction of winding up to the locked position P2.
- the candidate rotation reversal position PM2 can then be associated with the distance or travel time between the positions PM2 and P2.
- the sequence a), b) is then repeated until the free end of the apron 2, namely the lower blade 5 of the apron 2, exceeds the output position P4, beyond which the locking of the motorized display 1 is no longer activated when the motorized display 1 is driven in the direction of winding.
- the apron 2 is driven in the unwinding direction to a third candidate rotational reversing position PM3 situated beyond the first rotational reversing position PM1 in the direction of unwinding of the apron 2.
- the third position of PM3 candidate rotation inversion is located at a distance d from the previous candidate inversion position PM2, that is to say at a distance 2d from the first candidate inversion position PM1.
- the position PM3 is then stored in the memory 16 of the control unit 7 and the step b) is also reproduced: the winding of the deck 2 is carried out until the lower blade 5 is in the position P2 .
- step 110 the iteration of the sequence a) -b) continues.
- the decision of the interruption of the sequence a) -b) can be taken after a predetermined time has elapsed since starting the winding.
- Interrupting the iteration sequence a) -b) after one or more iterations validates the configuration of the device.
- the angular position value D4 of the winding tube corresponding to the position P4 is then automatically defined from the last rotational reversing position, in the example above the position PM4 before the interruption of the sequence a ) -b).
- the value of the optimum position selected is used in the mode of use of the motorized screen installation 1.
- the motorized screen installation 1 first performs a rotation action of the winding tube 4 in the direction of unwinding of the apron 2.
- the position sensor 10 detects that the tube d 4 has reached the optimum position corresponding to the fact that the lower blade 5 is in the optimum position
- the motorized screen installation 1 performs an action to stop the rotational movement of the winding tube 4.
- the installation motorized screen 1 then executes immediately a rotation action of the winding tube 4 in the direction of winding until the position D2 is reached, meaning that the lower blade 5 is locked in position P2 and C nc the deck has reached the requested safe ventilation position.

Description
L'invention concerne le domaine des installations d'Ă©lĂ©ments enroulables motorisĂ©es. Elle concerne plus particulièrement un procĂ©dĂ© de rĂ©glage automatisĂ© d'une installation comprenant un Ă©cran motorisĂ©, ou volet roulant motorisĂ©, configurĂ© pour Ăªtre dĂ©placĂ© entre une position infĂ©rieure et une position supĂ©rieure, l'Ă©cran motorisĂ© comprenant un tablier muni d'une extrĂ©mitĂ© libre ou lame infĂ©rieure, l'installation Ă©tant munie d'un mĂ©canisme de blocage ou d'ancrage, coopĂ©rant avec la lame infĂ©rieure, pour bloquer le mouvement de celle-ci lors d'un dĂ©placement vers la position supĂ©rieure.The invention relates to the field of installations of motorized rollable elements. It relates more particularly to an automated control method of an installation comprising a motorized screen, or motorized roller shutter, configured to be moved between a lower position and a higher position, the motorized screen comprising an apron provided with a free end or lower blade, the installation being provided with a locking mechanism or anchoring, cooperating with the lower blade, to block the movement thereof when moving to the upper position.
Les installations d'Ă©cran ou d'Ă©lĂ©ments enroulables motorisĂ©s connues comprennent en gĂ©nĂ©ral un Ă©cran, tel qu'un tablier formĂ© de lames articulĂ©es et empilables, ou encore un ensemble comprenant une toile et une barre de charge lestĂ©e, le tablier Ă©tant enroulable autour d'un tube d'enroulement situĂ© dans la partie supĂ©rieure de l'installation, grĂ¢ce Ă des moyens d'entraĂ®nement motorisĂ©s ou actionneur. La lame finale, ou lame infĂ©rieure situĂ©e Ă l'extrĂ©mitĂ© libre infĂ©rieure du tablier ou barre de charge de la toile, est guidĂ©e par des rails situĂ©s de part et d'autre d'une ouverture Ă masquer. Cette lame infĂ©rieure peut Ăªtre dĂ©placĂ©e entre une position extrĂªme infĂ©rieure, par exemple en contact avec un seuil de l'ouverture et une position extrĂªme supĂ©rieure, par exemple au niveau d'un caisson dans lequel s'enroule l'Ă©cran. Ces installations peuvent comprendre Ă©galement des mĂ©canismes de blocage, tels que des moyens de verrouillage permettant de maintenir la lame infĂ©rieure ou la barre de charge de l'Ă©cran dans une position dĂ©terminĂ©e tout en Ă©vitant que celle-ci ne soit soulevĂ©e par effraction ou claque sous les actions du vent. De telles installations sont notamment utilisĂ©es pour des volets offrant une position de ventilation sĂ©curisĂ©e, les lames Ă©tant Ă©cartĂ©es les unes des autres et Ă©tant Ă©cartĂ©es du seuil de l'ouverture. D'autres mĂ©canismes de blocage permettent une orientation de lames orientables d'un volet roulant, telle que dĂ©crite dans la demande
A cet effet, les mécanismes de blocage de telles installations sont configurés de sorte que lors du déplacement de l'écran motorisé dans un premier sens, par exemple lors du déroulement, 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 mécanisme de blocage, puis, à la suite d'un mouvement inverse, dans un deuxième sens, se bloque dans le mécanisme de blocage.For this purpose, the locking mechanisms of such installations are configured so that when moving the motorized screen in a first direction, for example during unwinding, the final blade of the screen, that is to say the blade the bottom of the hinged leaf shutter or the load bar of a fabric, enters the locking mechanism, then, following a reverse movement, in a second direction, locks in the locking mechanism.
Ces différents déplacements 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 motorisé 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.These different displacements are preferably motorized. An actuator is generally placed in the winding tube and responds to commands from a user via a control interface such as a remote control or a wall interface. The actuator comprises a motor and a gearbox and an electronic control unit comprising electric or electronic means for managing the movement of the motorized screen according to the orders received and as a function of detected events. These electrical or electronic means may, for this purpose, include detectors or sensors position, torque or travel time.
On connaît par exemple de la demande
Au cours du procédé d'apprentissage, l'installateur procède à l'enregistrement de la valeur d'une position angulaire du tube d'enroulement choisie, dite position d'inversion de rotation enregistrée. Cette position est située, dans le sens de déroulement de l'écran motorisé, au niveau ou au-delà de la troisième position (position d'inversion de rotation). A cet effet, l'utilisateur doit placer la lame inférieure du volet ou la barre de charge de la toile dans une zone repérée par des marquages sur les rails de guidage ou les moyens de verrouillage.During the learning process, the installer proceeds to record the value of an angular position of the selected winding tube, called the recorded reversal position. This position is located, in the direction of unwinding of the motorized screen, at or beyond the third position (rotation reversal position). For this purpose, the user must place the blade bottom of the shutter or the load bar of the fabric in an area marked by markings on the guide rails or the locking means.
Cependant, cette opĂ©ration est parfois ardue pour l'utilisateur, qui doit souvent procĂ©der par tĂ¢tonnements. De plus, un risque d'erreur de positionnement existe. Enfin, il existe un besoin de conception d'installations d'Ă©cran motorisĂ© munies de mĂ©canismes de blocage, dont le rĂ©glage et la mise en service ne nĂ©cessitent plus ou peu d'intervention humaine.However, this operation is sometimes difficult for the user, who must often proceed by trial and error. In addition, a risk of positioning error exists. Finally, there is a need for the design of motorized screen installations equipped with locking mechanisms, the setting and commissioning of which require little or no human intervention.
L'invention a pour but de remédier à ces inconvénients en proposant un procédé de réglage d'une installation d'un écran motorisé comprenant un tablier enroulable sur un tube d'enroulement, un actionneur de manoeuvre du tube d'enroulement de manière à déplacer le tablier suivant un premier sens de déplacement et un deuxième sens de déplacement, et un mécanisme de blocage de l'extrémité libre du tablier définissant une position dite bloquée dans le deuxième sens de déplacement du tablier, le blocage étant activé dans le deuxième sens de déplacement du tablier si l'extrémité libre du tablier atteint préalablement au moins une position d'entrée dans le mécanisme de blocage, située au-delà de la position bloquée, dans le premier sens de déplacement du tablier, l'installation d'écran motorisé étant munie d'un moyen de mesure d'un paramètre lié au mouvement de l'écran motorisé,
caractérisé en ce qu'il comprend les étapes suivantes :
- analyse des variations du paramètre lié au mouvement de l'écran motorisé au cours d'un déplacement de l'écran motorisé ;
- détermination, à partir de cette analyse, de la position d'entrée dans le mécanisme de blocage.
characterized in that it comprises the following steps:
- analyzing variations of the parameter related to the movement of the motorized screen during a movement of the motorized screen;
- determination, from this analysis, of the entry position in the locking mechanism.
GrĂ¢ce Ă l'analyse des variations du paramètre liĂ© au mouvement de l'Ă©cran motorisĂ© au cours d'un dĂ©placement de l'Ă©cran motorisĂ©, on dĂ©termine automatiquement une position d'entrĂ©e dans le mĂ©canisme de blocage qui pourra servir de position d'inversion de rotation candidate pour l'apprentissage automatique de la position d'inversion de rotation. Ceci permet d'Ă©viter que l'utilisateur ait Ă placer la lame infĂ©rieure du volet ou la barre de charge de la toile dans une zone repĂ©rĂ©e par des marquages sur les rails de guidage ou le mĂ©canisme de blocage.Thanks to the analysis of the variations of the parameter linked to the movement of the motorized screen during a movement of the motorized screen, an input position is automatically determined in the locking mechanism which can serve as an inversion position. of rotation candidate for the automatic learning of the position of inversion of rotation. This avoids the user having to place the lower blade of the shutter or the load bar of the fabric in an area marked by markings on the guide rails or the locking mechanism.
Selon un mode de réalisation préféré de l'invention, les étapes d'analyse des variations du paramètre et de détermination de la position d'entrée sont mises en oeuvre par l'actionneur.According to a preferred embodiment of the invention, the steps of analyzing the parameter variations and determining the input position are implemented by the actuator.
Selon un mode de rĂ©alisation prĂ©fĂ©rĂ© de l'invention rendant simple la dĂ©termination de la position d'entrĂ©e dans le mĂ©canisme de blocage, la position d'entrĂ©e dans le mĂ©canisme de blocage est obtenue Ă partir de la dĂ©termination d'une position de rĂ©fĂ©rence, la position de rĂ©fĂ©rence Ă©tant associĂ©e Ă la dĂ©tection d'une valeur maximum locale du paramètre ou Ă la dĂ©tection d'une valeur de variation maximum locale du paramètre. Ainsi, le procĂ©dĂ© de rĂ©glage peut Ăªtre rĂ©alisĂ© entièrement automatiquement, sans intervention d'un installateur ou d'un utilisateur pour dĂ©finir la position de rĂ©fĂ©rence associĂ©e au mĂ©canisme de blocage.According to a preferred embodiment of the invention making it simple to determine the input position in the locking mechanism, the input position in the locking mechanism is obtained from the determination of a reference position, the reference position being associated with the detection of a local maximum value of the parameter or the detection of a maximum local variation value of the parameter. Thus, the adjustment process can be performed entirely automatically, without the intervention of an installer or a user to define the reference position associated with the locking mechanism.
De prĂ©fĂ©rence, la position d'entrĂ©e dans le mĂ©canisme de blocage est obtenue par un dĂ©calage d'une valeur prĂ©dĂ©terminĂ©e Ă partir de la position de rĂ©fĂ©rence. Ce dĂ©calage peut notamment Ăªtre liĂ© Ă des considĂ©rations gĂ©omĂ©triques du mĂ©canisme de blocage ou de sa localisation dans l'installation.Preferably, the input position in the locking mechanism is obtained by an offset of a predetermined value from the reference position. This offset may notably be related to geometric considerations of the locking mechanism or its location in the installation.
Ainsi, dans la plupart des installations, lorsque le mĂ©canisme de blocage est situĂ© Ă proximitĂ© de la position de rĂ©fĂ©rence, la position d'entrĂ©e du mĂ©canisme de blocage pourra Ăªtre dĂ©finie Ă partir de la position de rĂ©fĂ©rence repĂ©rĂ©e automatiquement.Thus, in most installations, when the locking mechanism is located near the reference position, the input position of the locking mechanism can be defined from the reference position automatically identified.
Selon un mode de rĂ©alisation prĂ©fĂ©rĂ© de l'invention, le paramètre est le couple exercĂ© par l'actionneur entraĂ®nant en mouvement le tablier dans le deuxième sens de dĂ©placement. Le couple est en effet un paramètre dont les variations peuvent Ăªtre dĂ©tectĂ©es de façon fiable et simple.According to a preferred embodiment of the invention, the parameter is the torque exerted by the actuator causing the apron to move in the second direction of movement. Torque is indeed a parameter whose variations can be reliably and easily detected.
De préférence, le couple est déterminé à partir d'une mesure du courant traversant un moteur électrique de l'actionneur.Preferably, the torque is determined from a measurement of the current flowing through an electric motor of the actuator.
Selon un mode de réalisation préféré de l'invention, après les étapes d'analyse des variations du paramètre et de détermination de la position d'entrée dans le mécanisme de blocage et une étape d'enregistrement de la position d'entrée dans le mécanisme de blocage, l'écran motorisé est positionné dans la position d'entrée par un mouvement dans le premier sens de déplacement puis entraîné dans le deuxième sens de déplacement jusqu'à la position bloquée, puis, la séquence suivante est effectuée :
- a) l'écran motorisé est entraîné dans premier sens de déplacement du tablier jusqu'à une position d'inversion de rotation candidate décalée par rapport à la position d'entrée dans le mécanisme de blocage,
- b) l'écran motorisé est entraîné dans le deuxième sens de déplacement du tablier jusqu'à la position bloquée,
- a) the motorized screen is driven in the first direction of movement of the apron to a position of rotation reversal candidate offset from the entry position in the locking mechanism,
- b) the motorized screen is driven in the second direction of movement of the deck to the locked position,
GrĂ¢ce Ă la rĂ©pĂ©tition de la sĂ©quence a)-b), il est possible de tester des positions d'inversion de rotation candidates diffĂ©rentes de celle ayant Ă©tĂ© initialement dĂ©finie par l'analyse des variations du paramètre liĂ© au mouvement de l'Ă©cran motorisĂ©. Ainsi, l'on peut choisir parmi les positions candidates celle se trouvant Ă la fois suffisamment Ă©loignĂ©e de la position de sortie et de la position de butĂ©e. Ce procĂ©dĂ© permet d'affiner les rĂ©glages obtenus automatiquement, sans nĂ©cessiter non plus d'intervention de l'installateur ou de l'utilisateur.Thanks to the repetition of the sequence a) -b), it is possible to test candidate rotation reversal positions different from that initially defined by the analysis of the variations of the parameter related to the movement of the motorized screen. Thus, one can choose from the candidate positions that is both sufficiently far from the output position and the stop position. This method makes it possible to refine the settings obtained automatically, without requiring any intervention of the installer or the user.
Ceci a son importance, car lors des cycles de dĂ©placement et d'inversions de sens dans le mĂ©canisme de blocage, on fait intervenir des dĂ©tecteurs ou capteurs de couple associĂ©s Ă l'actionneur et dont l'activation nĂ©cessite que l'actionneur ait atteint un rĂ©gime stable ou rĂ©gime nominal. Cela tient notamment au fait que le couple que doit fournir l'actionneur au dĂ©marrage est souvent plus Ă©levĂ© que des seuils prĂ©dĂ©finis caractĂ©ristiques d'un obstacle ou d'une arrivĂ©e du volet en butĂ©e, et/ou au fait que la valeur de dĂ©tection comparable au seuil est obtenue Ă partir d'un ensemble de mesures lors du fonctionnement de l'actionneur en rĂ©gime nominal. Ainsi, un dĂ©lai allant jusqu'Ă 500ms peut survenir entre un dĂ©marrage de l'actionneur et l'activation des dĂ©tecteurs de couple de l'actionneur. Par consĂ©quent, il est souhaitable que la position d'inversion de sens enregistrĂ©e soit suffisamment Ă©loignĂ©e de la position d'arrĂªt dans le mĂ©canisme de blocage pour Ă©viter que la lame infĂ©rieure du volet ne se trouve prĂ©maturĂ©ment en butĂ©e dans le mĂ©canisme de blocage alors que l'actionneur est en cours de fonctionnement, la dĂ©tection de couple n'Ă©tant pas encore active ou opĂ©rationnelle, et pour Ă©viter que l'actionneur n'exerce ainsi des efforts importants sur le mĂ©canisme de blocage pouvant l'endommager. Le mĂ©canisme de blocage comprend en effet des parties flexibles ou mobiles fragiles si elles sont soumises Ă des efforts mĂ©caniques importants et/ou rĂ©pĂ©tĂ©s.This is important because during the movement cycles and reversals of direction in the locking mechanism, sensors or torque sensors associated with the actuator are used and whose activation requires that the actuator has reached a certain point. steady state or rated speed. This is due in particular to the fact that the torque to be supplied by the actuator when starting is often higher than predefined thresholds characteristic of an obstacle or arrival of the flap in abutment, and / or the fact that the detection value comparable at the threshold is obtained from a set of measurements during operation of the actuator in nominal mode. Thus, a delay of up to 500ms can occur between a start of the actuator and the activation of the torque sensors of the actuator. Therefore, it is desirable that the recorded reversing position is sufficiently far from the stop position in the locking mechanism to prevent the bottom blade of the flap from being prematurely abutted in the locking mechanism while the actuator is in operation, the torque detection is not yet active or operational, and to prevent the actuator thus exerts significant effort on the locking mechanism that may damage it. The locking mechanism in fact comprises flexible or mobile fragile parts if they are subjected to significant mechanical forces and / or repeated.
A l'inverse, au cours de la vie du volet, les articulations reliant les lames du tablier peuvent se détendre. De ce fait, si la position d'inversion de sens enregistrée par l'utilisateur se trouve trop proche de la position de sortie du mécanisme de blocage, une partie ou toute la lame inférieure pourrait finir par sortir du mécanisme de blocage. Il est donc également souhaitable de s'assurer que la position d'inversion de sens soit choisie de sorte qu'elle soit suffisamment éloignée de la position de sortie du mécanisme de blocage.Conversely, during the life of the shutter, the joints connecting the apron blades can relax. As a result, if the user reversing direction position is too close to the exit position of the locking mechanism, a portion or the entire lower blade may eventually exit the locking mechanism. It is therefore also desirable to ensure that the reversal position is chosen so that it is sufficiently far away from the exit position of the locking mechanism.
Par ailleurs, la position d'installation et/ou les dimensions du mĂ©canisme de blocage peuvent Ăªtre variables et les durĂ©es d'activation des dĂ©tections de couple peuvent Ă©galement diffĂ©rer d'un actionneur Ă un autre. Il est donc nĂ©cessaire de pouvoir affiner les rĂ©glages pour chaque installation.Furthermore, the installation position and / or the dimensions of the locking mechanism can be variable and the activation times of the torque detections can also differ from one actuator to another. It is therefore necessary to be able to refine the settings for each installation.
Selon un mode de réalisation préféré de l'invention, chaque position d'inversion de rotation candidate est enregistrée dans une mémoire d'une unité de commande de l'installation d'écran motorisé.According to a preferred embodiment of the invention, each candidate rotational inversion position is stored in a memory of a control unit of the motorized screen installation.
De la mĂªme manière, les distances entre les positions d'inversion de rotation candidates et la position bloquĂ©e sont mises en mĂ©moire. Ces distances peuvent Ăªtre respectivement associĂ©es Ă la position bloquĂ©e et Ă ces positions d'inversion de rotation candidates. Il est ainsi possible, Ă partir de ces donnĂ©es mĂ©morisĂ©es, de dĂ©terminer facilement une position d'inversion de rotation optimale.In the same way, the distances between the candidate rotation reversing positions and the locked position are stored. These distances can be respectively associated with the locked position and these candidate rotation inversion positions. It is thus possible, from these stored data, to easily determine an optimal rotational inversion position.
Selon un mode de réalisation préféré de l'invention, afin de faciliter l'automatisation de l'itération de la séquence a)-b), chaque position d'inversion de rotation candidate d'une nouvelle itération de la séquence est située à une distance prédéterminée d de la précédente position d'inversion de rotation candidate.According to a preferred embodiment of the invention, in order to facilitate the automation of the iteration of the sequence a) -b), each candidate rotation inversion position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate inversion position.
Selon un mode de réalisation préféré de l'invention, l'interruption de l'itération de la séquence a)-b) est décidée par détection d'une absence d'obstacle lors de l'enroulement de l'écran motorisé au niveau de la position bloquée ou pendant une durée prédéterminée à partir du démarrage de l'enroulement.According to a preferred embodiment of the invention, the interruption of the iteration of the sequence a) -b) is decided by detecting an absence of obstacle during the winding of the motorized screen at the level of the locked position or for a predetermined time from the starting of the winding.
De manière à détecter la position bloquée de façon simple et rapide, la valeur de position angulaire du tube d'enroulement correspondant à la position bloquée est déterminée à l'aide d'un détecteur ou capteur de position du tube d'enroulement ou à l'aide d'un compteur de temps.In order to detect the locked position simply and quickly, the angular position value of the winding tube corresponding to the locked position is determined with the aid of a winding tube position sensor or sensor. using a time counter.
De préférence, la position bloquée est enregistrée par une mémoire d'une unité de commande de l'installation d'écran motorisé après détection de la valeur de position angulaire du tube d'enroulement correspondant à la position bloquée.Preferably, the locked position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the locked position.
De manière à détecter la position bloquée de façon simple et rapide, la valeur de position angulaire du tube d'enroulement correspondant à la position de sortie est mesurée à l'aide d'un capteur de couple d'entraînement du tablier.In order to detect the locked position in a simple and fast manner, the angular position value of the winding tube corresponding to the output position is measured by means of an apron drive torque sensor.
De préférence, la position de sortie est enregistrée par une mémoire d'une unité de commande de l'installation d'écran motorisé après détection de la valeur de position angulaire du tube d'enroulement correspondant à la position de sortie.Preferably, the output position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the output position.

Selon un mode de rĂ©alisation prĂ©fĂ©rĂ© de l'invention, de manière Ă obtenir une ergonomie simple du rĂ©glage automatique de l'installation pour l'utilisateur, l'installation comprend en outre un dispositif d'activation d'une fonction de dĂ©placement du tablier commandĂ©e par un Ă©lĂ©ment d'activation destinĂ© Ă Ăªtre actionnĂ© par un utilisateur, par exemple un bouton d'activation, dans lequel l'actionnement de l'Ă©lĂ©ment d'activation permet Ă©galement le dĂ©clenchement des Ă©tapes d'analyse des variation du paramètre et de dĂ©termination de la position d'entrĂ©e dans le mĂ©canisme de blocage.According to a preferred embodiment of the invention, so as to obtain a simple ergonomics of the automatic adjustment of the installation for the user, the installation further comprises a device for activating a function for moving the controlled deck. by an activation element intended to be actuated by a user, for example an activation button, in which the actuation of the activation element also makes it possible to trigger the steps for analyzing the variation of the parameter and for determining from the entry position in the locking mechanism.

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.

De préférence, le tablier 2 comporte un ensemble de lames empilables reliée les unes aux autres par des parties escamotables et ajourées.The motorized screen 1 may in particular consist of a closure element, occultation or sun protection. In the example shown in the figures, it is an
Les dĂ©placements du tablier 2 sont commandĂ©s par les dĂ©placements de rotation du tube d'enroulement 4, dont l'entraĂ®nement est assurĂ© par exemple Ă l'aide d'un actionneur comprenant par exemple un ensemble motorĂ©ducteur tubulaire (non reprĂ©sentĂ©) disposĂ© Ă l'intĂ©rieur du tube d'enroulement 4. L'ensemble motorĂ©ducteur comprend notamment un moteur et un rĂ©ducteur, en particulier un rĂ©ducteur Ă©picycloĂ¯dal. Le moteur peut Ăªtre de type Ă courant continu et Ă balais et collecteur, Ă courant continu et Ă commutation Ă©lectronique (Brushless Direct Current motor en langue anglaise) ou asynchrone.

On notera toutefois que d'autres sens de dĂ©placement pourraient Ăªtre envisagĂ©s pour des configurations d'installation d'Ă©cran motorisĂ© diffĂ©rentes, notamment en inversant le sens de l'enroulement et le sens du dĂ©roulement.The
L'interface utilisateur 8 peut Ăªtre reliĂ©e Ă l'unitĂ© de commande 7 par des moyens de communication filaire ou non filaire tels que des ondes radioĂ©lectriques ou des rayons infrarouges. L'interface utilisateur 8 comprend par exemple deux touches qui permettent Ă un utilisateur de commander respectivement un dĂ©placement de l'Ă©cran motorisĂ© 1 vers le haut ou vers le bas. Une combinaison de touches permet Ă©galement de dĂ©placer l'Ă©cran motorisĂ© 1 dans une position de blocage, dĂ©finie plus loin. Dans une variante, l'interface utilisateur comprend une touche spĂ©cifique dont l'activation permet le dĂ©placement de l'Ă©cran motorisĂ© 1 dans la position de blocage. L'interface utilisateur 8 est par exemple une tĂ©lĂ©commande portative.The user interface 8 may be connected to the
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
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.Note that in what follows, it is considered that the
Une première position P1 de la barre de charge ou de l'extrémité libre du tablier 2 correspond à une position d'ouverture complète du tablier 2. A cette position correspond une position angulaire D1 du tube d'enroulement 4, comme représenté à la
Le long des rails de guidage disposĂ©s de part et d'autre de l'ouverture, le l'installation 1 comprend un mĂ©canisme de blocage, reprĂ©sentĂ© ici sous forme de moyens de verrouillage 18. Le mĂ©canisme de blocage peut Ăªtre logĂ© Ă l'intĂ©rieur des rails de guidage et comprend notamment deux ensembles similaires de part et d'autre du tablier 2 de l'Ă©cran motorisĂ© 1. Les moyens de verrouillage 18 coopèrent avec les extrĂ©mitĂ©s de la lame infĂ©rieure 5, en particulier avec des ergots fixĂ©s Ă©lastiquement aux extrĂ©mitĂ©s de la lame finale (non reprĂ©sentĂ©s). Ces moyens de verrouillage 18, reprĂ©sentĂ©s Ă la
La deuxième position P2 est une position dite verrouillée dans laquelle le tablier 2 est bloqué lors d'un mouvement de montée (ou enroulement). La deuxième position P2 correspond à une position angulaire verrouillée D2 du tube d'enroulement 4.The second position P2 is a so-called locked position in which the
La troisième position P3 est une position d'entrée des moyens de verrouillage. Lorsque la lame inférieure 5 dépasse cette position P3 dans le sens du déroulement du tablier 2 et qu'ensuite un mouvement d'enroulement de l'écran motorisé 1 est commandé, le tablier 2 se retrouve bloqué sous la première rampe, la lame inférieure 5 se retrouvant en position P2 et le tube d'enroulement en position D2. Cette position P3 correspond à une position angulaire d'inversion D3 du tube d'enroulement 4.The third position P3 is an input position of the locking means. When the
La quatrième position P4 est une position dite de sortie des moyens de verrouillage en dessous de laquelle la lame infĂ©rieure 5, ayant Ă©tĂ© verrouillĂ©e, doit venir afin que le tablier 2 puisse de nouveau Ăªtre enroulĂ© jusqu'Ă atteindre sa position d'ouverture totale P1. Cette position correspond Ă une position angulaire de sortie D4 du tube d'enroulement 4. La position P4 est une position infĂ©rieure Ă la position P3, cette position P3 Ă©tant infĂ©rieure Ă la position P2.The fourth position P4 is a so-called exit position of the locking means below which the

On va maintenant décrire une procédure d'exécution du procédé de réglage selon l'invention en référence aux
De prĂ©fĂ©rence, le procĂ©dĂ© de rĂ©glage va Ăªtre dĂ©clenchĂ© par l'actionnement d'un dispositif d'activation Ă partir d'un Ă©lĂ©ment d'activation destinĂ© Ă Ăªtre actionnĂ© par l'utilisateur. Par exemple, le procĂ©dĂ© de rĂ©glage va Ăªtre dĂ©clenchĂ© lors de l'installation du volet roulant par exemple, par appui sur une combinaison de touches de l'interface utilisateur 8, ou par simple appui sur une touche spĂ©cifique.Preferably, the setting method will be triggered by the actuation of an activation device from an activation element to be actuated by the user. For example, the setting process will be triggered during the installation of the roller shutter for example, by pressing a combination of keys of the user interface 8, or by simply pressing a specific key.
En particulier, cette combinaison de touches ou l'appui sur une touche particulière va enclencher une première étape 80 d'analyse des variations d'un paramètre lié au mouvement de l'écran motorisé 1 au cours du déplacement de l'écran motorisé 1. Dans le mode de réalisation particulier décrit ici, cette analyse est réalisée par l'actionneur.In particular, this combination of keys or the pressing of a particular key will trigger a first step 80 of analyzing the variations of a parameter related to the movement of the motorized screen 1 during the movement of the motorized screen 1. In the particular embodiment described here, this analysis is performed by the actuator.
Les variations du paramètre permettent notamment d'identifier des positions particulières de la lame inférieure 5 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. Dans le mode de réalisation particulier décrit ici, cette analyse est réalisée par l'actionneur, en particulier par l'unité électronique de commande 7 de l'actionneur.The variations of the parameter make it possible in particular to identify particular positions of the
Les variations de couple observées au cours de ce mouvement de montée (ou d'ouverture) de l'écran motorisé 1 sont représentées de manière schématique en fonction de la position angulaire du tube d'enroulement 4 à la
La position dans laquelle la lame infĂ©rieure 5 est dĂ©collĂ©e du seuil du volet peut Ăªtre repĂ©rĂ©e de manière fiable par la dĂ©termination d'un maximum local de couple, au voisinage du mĂ©canisme de blocage. Cette position de dĂ©collement, ou position de rĂ©fĂ©rence PMB, permet de dĂ©terminer la position d'entrĂ©e dans les moyens de verrouillage P3 qui sont espacĂ©es par une distance prĂ©dĂ©terminĂ©e, qui dĂ©pend des caractĂ©ristiques du volet.The position in which the
Ainsi, au cours d'une deuxième étape 90 qui sera déclenchée après l'étape 80, on détermine, à partir de l'analyse réalisée à l'étape précédente, la position de référence PMB par détection d'une valeur maximum locale du paramètre ou d'une valeur de variation maximum locale du paramètre. Dans le mode de réalisation particulier décrit ici, cette détermination est réalisée par l'actionneur et par comparaison à un seuil de couple.Thus, during a
Puis, au cours d'une étape 100, on détermine la position d'entrée dans les moyens de verrouillage P3. Plus particulièrement, la position d'entrée dans les moyens de verrouillage P3 est obtenue par décalage d'une valeur prédéterminée à partir de la position de référence PMB. Ce décalage prend notamment en compte la géométrie et/ou les dimensions du mécanisme de blocage, ainsi que la position préférentielle de montage de celui-ci dans l'installation, notamment au bas des rails de guidage. En particulier, la position angulaire D3 associée à la position P3 est liée à la position angulaire DMB associée à la position de décollement par la relation suivante : D3 = DMB+360°.Then, during a
La dĂ©termination de la position de rĂ©fĂ©rence PMB se fait notamment lors d'un mouvement de montĂ©e ou d'enroulement du tablier. Le procĂ©dĂ© de rĂ©glage peut cependant Ăªtre poursuivi, notamment pour affiner cette position d'entrĂ©e P3 dans le mĂ©canisme de blocage. Ainsi, d'autres mouvements sont ensuite mis en oeuvre par l'actionneur, notamment un mouvement de descente ou de dĂ©roulement, conduisant la lame infĂ©rieure 5 dans la position P3 lors d'un mouvement de dĂ©roulement. La lame infĂ©rieure 5 se trouve alors dans les moyens de verrouillage et dans une zone dite d'inversion de sens. Dans cette zone d'inversion de sens, une inversion du sens de dĂ©placement de la lame infĂ©rieure 5, d'un mouvement de descente Ă un mouvement de montĂ©e, provoque un blocage de la lame infĂ©rieure 5 dans les moyens de verrouillage 18. Hors de cette zone, l'inversion de sens de dĂ©placement de la lame infĂ©rieure 5 ne produit pas d'effet particulier. La lame infĂ©rieure 5 peut notamment traverser les moyens de verrouillage 18 dans le sens de la descente comme dans le sens de la montĂ©e sans Ăªtre verrouillĂ©e s'il ne se produit pas d'inversion de son sens de dĂ©placement entre les positions P3 et P4.The determination of the reference position PMB is done in particular during an upward movement or winding of the deck. The adjustment process can however, to be continued, in particular to refine this input position P3 in the locking mechanism. Thus, other movements are then implemented by the actuator, including a descent or unwinding movement, leading the
La position P3 déterminée au terme de l'étape de détermination 100 est choisie comme première position d'inversion de rotation candidate PM1. Elle correspond à une position angulaire DM1.The position P3 determined at the end of the
Durant une étape 102, la position P3 est enregistrée dans la mémoire 16 de l'unité électronique de commande 7. Puis, la lame inférieure 5 est déplacée, dans le sens du déroulement, jusqu'à cette position P3 ainsi enregistrée.During a
Par la suite, au cours d'une étape 104 déclenchée de préférence automatiquement, le tablier 2 est ensuite entraîné dans le sens de l'enroulement jusqu'à la position verrouillée P2. A cet effet, une alimentation du motoréducteur est commandée provoquant l'enroulement du tablier 2 et par conséquent la montée de la lame inférieure 5. Dans une variante, l'étape 104 pourrait également faire suite à une action de l'installateur.Subsequently, during a
Une fois la lame inférieure 5 bloquée dans les moyens de verrouillage 18, au cours d'une étape 106, la deuxième position P2 est détectée par le capteur de couple 12, par exemple par détection d'un surcouple, et l'alimentation du motoréducteur est coupée. La valeur de position angulaire D2 du tube d'enroulement 4 correspondant à la position P2 de la lame inférieure est alors enregistrée en mémoire dans l'unité de commande 7. On notera que la valeur de P2 enregistrée peut correspondre à une position légèrement inférieure à la position de blocage de la lame inférieure 5, de manière à ce qu'une fois dans le mode d'utilisation, lorsqu'un utilisateur commande le verrouillage du tablier 2, la lame inférieure 5 ne vienne pas en butée en exerçant des efforts importants sur les moyens de verrouillage 18.Once the
Après enregistrement de la position P2, une séquence itérative est initiée. Cette séquence comprend au moins deux étapes a) et b).After registering the position P2, an iterative sequence is initiated. This sequence comprises at least two steps a) and b).
Au cours de l'étape a), ou 108 telle que représentée sur le schéma de la
De préférence, la deuxième position d'inversion de rotation candidate est située à une distance prédéterminée d de la première position d'inversion de rotation candidate. Ainsi, comme illustré à la
La position d'inversion de rotation candidate PM2 définie par l'unité électronique de commande 7 est mise en mémoire 16 de l'unité de commande 7.The candidate rotation reversing position PM2 defined by the
Puis, au cours de l'étape b), ou 110 telle que représentée sur le schéma de la
La séquence a), b) est ensuite répétée jusqu'à ce que l'extrémité libre du tablier 2, à savoir la lame inférieure 5 du tablier 2, dépasse la position de sortie P4, au-delà de laquelle le verrouillage de l'écran motorisé 1 n'est plus activé lorsque l'écran motorisé 1 est entraîné dans le sens de l'enroulement.The sequence a), b) is then repeated until the free end of the
Dans l'exemple d'application du mode de réalisation du procédé illustré à la
La position PM3 est alors enregistrée dans la mémoire 16 de l'unité de commande 7 et l'étape b) se reproduit également : l'enroulement du tablier 2 est effectuée jusqu'à ce que la lame inférieure 5 se retrouve dans la position P2.The position PM3 is then stored in the
Puis, dans l'exemple illustré à la
Tant qu'un obstacle est dĂ©tectĂ© au niveau de P2 lors de la remontĂ©e du tablier 2 lors de l'Ă©tape b) (Ă©tape 110), l'itĂ©ration de la sĂ©quence a)-b) se poursuit. Dans une variante, ou en complĂ©ment de l'Ă©tape 112, la dĂ©cision de l'interruption de la sĂ©quence a)-b) peut Ăªtre prise après que se soit Ă©coulĂ©e une durĂ©e prĂ©dĂ©terminĂ©e Ă partir du dĂ©marrage de l'enroulement.As long as an obstacle is detected at P2 during the ascent of the
L'interruption de l'itération séquence a)-b) après une ou plusieurs itération permet de valider la configuration du dispositif. La valeur de position angulaire D4 du tube d'enroulement correspondant à la position P4 est alors automatiquement définie à partir de la dernière position d'inversion de rotation, dans l'exemple ci-dessus la position PM4 avant l'interruption de la séquence a)-b).Interrupting the iteration sequence a) -b) after one or more iterations validates the configuration of the device. The angular position value D4 of the winding tube corresponding to the position P4 is then automatically defined from the last rotational reversing position, in the example above the position PM4 before the interruption of the sequence a ) -b).
GrĂ¢ce Ă l'enregistrement des diffĂ©rentes positions d'inversion de rotations candidates PM1, PM2, PM3, notamment associĂ©es aux distances entre ces positions et la position P2, on peut choisir parmi celles-ci la position la plus adĂ©quate ou optimale, Ă savoir n'Ă©tant ni trop proche de P2, ni trop proche de P4. Il peut par exemple s'agir dans l'exemple reprĂ©sentĂ© sur les figures de PM2. On peut Ă©galement sĂ©lectionner une position d'inversion de rotation optimale comme Ă©tant une position intermĂ©diaire entre deux positions candidates prĂ©alablement enregistrĂ©es. Alternativement, la dernière position d'inversion de rotation candidate peut Ăªtre sĂ©lectionnĂ©e comme position d'inversion de rotation optimale.By recording the different positions of inversion of candidate rotations PM1, PM2, PM3, especially associated with the distances between these positions and the position P2, one can choose among these the most appropriate or optimal position, namely n 'being neither too close to P2, nor too close to P4. It can for example be in the example shown in the figures of PM2. It is also possible to select an optimal rotation reversal position as being an intermediate position between two previously registered candidate positions. Alternatively, the last candidate rotational inversion position can be selected as the optimal rotation inversion position.
La valeur de la position optimale retenue est utilisĂ©e dans le mode d'utilisation de l'installation d'Ă©cran motorisĂ© 1. En effet, lorsque l'utilisateur envoie Ă l'installation d'Ă©cran motorisĂ© 1, en position ouverture, un ordre de positionnement en ventilation sĂ©curisĂ©e, l'installation d'Ă©cran motorisĂ© 1 exĂ©cute tout d'abord une action de rotation du tube d'enroulement 4 dans le sens du dĂ©roulement du tablier 2. Puis, lorsque le capteur de position 10 dĂ©tecte que le tube d'enroulement 4 a atteint la position optimale correspondant au fait que la lame infĂ©rieure 5 se trouve en position optimale, l'installation d'Ă©cran motorisĂ© 1 exĂ©cute une action d'arrĂªt du mouvement de rotation du tube d'enroulement 4. L'installation d'Ă©cran motorisĂ© 1 exĂ©cute alors immĂ©diatement une action de rotation du tube d'enroulement 4 dans le sens de l'enroulement jusqu'Ă ce que la position D2 soit atteinte, signifiant que la lame infĂ©rieure 5 se trouve verrouillĂ©e en position P2 et donc que le tablier a atteint la position de ventilation sĂ©curisĂ©e demandĂ©e.The value of the optimum position selected is used in the mode of use of the motorized screen installation 1. In fact, when the user sends to the motorized screen installation 1, in the open position, an order of positioning in secure ventilation, the motorized screen installation 1 first performs a rotation action of the winding tube 4 in the direction of unwinding of the
Naturellement, les exemples reprĂ©sentĂ©s sur les figures et discutĂ©s ci-dessus ne sont donnĂ©s qu'Ă titre illustratif et non limitatif. Diverses variantes sont envisageables. En particulier, la description donnĂ©e Ă titre d'exemple de moyens de verrouillage est tout Ă fait applicable Ă©galement Ă d'autres types de mĂ©canismes de blocage fonctionnant de manière similaire. Les sens de dĂ©placement pour atteindre ou quitter la position de blocage peuvent Ăªtre adaptĂ©s en fonction des types de mĂ©canismes de blocage.Naturally, the examples shown in the figures and discussed above are given for illustrative and not limiting. Various variants are conceivable. 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. The directions of movement to reach or leave the locking position can be adapted according to the types of locking mechanisms.
