The installation is mounted on a wall 2 provided with an eave 3. A base 4 fixed to the wall supports a box 5 in which is wound a fabric 6, shown in dashed lines in the box and solid line outside of the box. The free end of the fabric is attached to a load bar 8, the latter being held by arms 7 fixed to the box or wall. The arms 7 are foldable arms under the action of an elastic force. The combined action of an actuator (not shown) and arms allows the deployment and folding of the fabric in the box.
L'actionneur est muni d'un module de commande (non représenté) et est alimenté par l'intermédiaire d'une réserve d'énergie 10 placée dans le caisson ou à proximité de celui-ci. Un panneau de cellules photovoltaïques est placé sur le caisson, de manière à optimiser la connexion électrique entre le panneau et la réserve d'énergie : un simple câble 1 1 passe dans le caisson.The actuator is provided with a control module (not shown) and is supplied via a power reserve 10 placed in or near the box. A panel of photovoltaic cells is placed on the box, so as to optimize the electrical connection between the panel and the energy reserve: a simple cable 1 1 passes into the box.
On connaît par ailleurs, par exemple du document FR2823527, une installation autonome de protection solaire, pour laquelle le panneau de cellules photovoltaïques est intégré à la toile du store. Ce type d'installation présente le désavantage de ne pas offrir de recharge possible lorsque le store reste dans une position enroulée. Un autre exemple d'une telle installation de protection solaire autonome est décrit dans le document DE20000681 U : le panneau de cellules photovoltaïques est monté sur la barre de charge. L'énergie récupérée par ces cellules est accumulée dans une réserve d'énergie située dans le caisson, grâce à un câble de connexion passant de la barre de charge vers le caisson via la toile ou via les bras. Un récepteur radio permet au store d'être piloté à distance.Also known, for example FR2823527 document, an autonomous solar protection system, for which the photovoltaic cell panel is integrated into the fabric of the blind. This type of installation has the disadvantage of not offering possible charging when the blind remains in a wound position. Another example of such an autonomous solar protection installation is described in document DE20000681 U: the photovoltaic cell panel is mounted on the load bar. The energy recovered by these cells is accumulated in a power reserve located in the box, through a connection cable passing from the load bar to the box via the fabric or via the arms. A radio receiver allows the blind to be controlled remotely.
Ces constructions permettent au store d'être installé facilement, dans la mesure où tous les éléments nécessaires à son fonctionnement sont intégrés. En revanche, il n'offre pas de solution réelle lorsque l'installation de protection solaire est montée sous un avant-toit débordant ou sous un balcon. Dans ce cas, le panneau de cellules photovoltaïques est également à l'abri du rayonnement solaire direct, ce qui diminue fortement ses possibilités de génération d'énergie.These constructions allow the awning to be easily installed, insofar as all the elements necessary for its operation are integrated. On the other hand, it does not offer a real solution when the sunscreen installation is mounted under an overhanging eave or under a balcony. In this case, the photovoltaic cell panel is also protected from direct solar radiation, which greatly reduces its possibilities of energy generation.
Il est alors connu de déporter le panneau de cellules photovoltaïques sur d'autres surfaces, par exemple le mur ou la surface exposée de l 'avant- toit. L'installation perd alors ses qualités de système intégré.It is then known to deport the photovoltaic cell panel to other surfaces, for example the wall or exposed surface of the eave. The installation then loses its qualities of integrated system.
Qu'il soit sur le caisson, la barre de charge ou déporté, le panneau est assez fortement exposé aux intempéries (pluie, grêle, neige). Les dégradations qu'elles peuvent causer (salissures ou dégradations non réparables) entament les performances du panneau. Il devient donc assez réaliste de placer l'installation à l'abri d'un balcon ou d'un avant- toit, malgré les problèmes décrits ci-dessus que cela engendre.Whether on the box, the load bar or remote, the panel is strongly exposed to the weather (rain, hail, snow). The damage they can cause (dirt or damage that can not be repaired) starts the performance of the panel. It therefore becomes quite realistic to place the installation away from a balcony or eave, despite the problems described above that this entails.
Le document DE20000681 U décrit également des particularités de fonctionnement, notamment liés à la réserve d'énergie. Un premier comportement a lieu lorsqu'un ordre de déploiement de la toile du store est donné. Cet ordre est inhibé si la réserve d'énergie n'est pas suffisante pour assurer le déploiement puis le repli consécutif de la toile.The document DE20000681 U also describes operating particularities, in particular related to the energy reserve. A first behavior occurs when an order to deploy the awning fabric given. This order is inhibited if the energy reserve is not sufficient to ensure the deployment and subsequent withdrawal of the fabric.
Un deuxième comportement a lieu lorsque, la toile étant déployée, le niveau d'énergie tombe en dessous d'un certain seuil. L'électronique de commande assure alors le repli de la toile, de manière à éviter que celle- ci ne reste en position déployée.A second behavior occurs when the canvas is deployed, the energy level falls below a certain threshold. The control electronics then ensures the folding of the fabric, so as to prevent it from remaining in the deployed position.
Par ailleurs, l'utilisation de différents capteurs (vent, pluie, température) influe également sur le comportement de l'installation.In addition, the use of different sensors (wind, rain, temperature) also influences the behavior of the installation.
Le but de l'invention est de fournir un procédé de fonctionnement d'un dispositif de store remédiant aux inconvénients évoqués et améliorant les procédés de fonctionnement connus de l'art antérieur. En particulier, l'invention permet d'assurer une charge de la réserve d'énergie même dans des conditions d'installation à l'abri des rayons solaires, par exemple lorsque le store est installé sous un avant-toit ou sous un balcon, et y compris lorsque le panneau de cellules photovoltaïques n'est pas exposé lorsque la toile du store est enroulée dans le caisson.The object of the invention is to provide a method of operation of a blind device overcomes the disadvantages mentioned and improving the known operating methods of the prior art. In particular, the invention makes it possible to ensure a charge of the energy reserve even under conditions of installation sheltered from the sun's rays, for example when the blind is installed under an eave or under a balcony, and also when the photovoltaic cell panel is not exposed when the awning fabric is wound in the box.
Le procédé selon l'invention régit le fonctionnement d'une installation domotique de protection solaire motorisée comprenant : un actionneur destiné à déployer et replier une toile, comprenant un moteur et un module de commande du moteur, et - un panneau de cellules photovoltaïques fixe ou mobile sous l'effet de l'actionneur, destiné à fournir de l'énergie pour recharger une réserve d'énergie électrique alimentant l'actionneur. Le procédé de fonctionnement comprend les étapes automatiques suivantes : a) détermination d'un critère de recharge de la réserve d'énergie, b) si le critère est rempli, déplacement du panneau de cellules photovoltaïques ou de la toile jusqu'à une position de recharge dans laquelle le panneau est exposé directement ou par réflexion aux rayons solaires pour recharger la réserve d'énergie.The method according to the invention governs the operation of a motorized solar protection home automation system comprising: an actuator intended to deploy and fold up a fabric, comprising a motor and an engine control module, and a fixed photovoltaic cell panel or mobile under the effect of the actuator, for supplying energy to recharge a reserve of electrical energy supplying the actuator. The operating method comprises the following automatic steps: a) determining a criterion for recharging the energy reserve, b) if the criterion is fulfilled, moving the photovoltaic cell panel or canvas to a recharging position in which the panel is exposed directly or by solar reflection to recharge the energy reserve.
Le critère de recharge peut correspondre à : un niveau d'énergie disponible dans la réserve d'énergie inférieur à un premier seuil prédéfini, et/ou une puissance convertie par le panneau de cellules photovoltaïques lorsque le store est dans une position de repli complet, inférieure à un deuxième seuil.The recharge criterion may correspond to: a level of energy available in the energy reserve less than a first predefined threshold, and / or a power converted by the photovoltaic cell panel when the blind is in a full fallback position, less than a second threshold.
La position de recharge peut être une position de déploiement partiel du store.The recharge position may be a partial deployment position of the blind.
La toile étant en position de recharge, elle peut être repliée si le taux de variation de l'énergie emmagasinée passe en-dessous d'un troisième seuil.The canvas being in the recharging position, it can be folded if the rate of change of stored energy passes below a third threshold.
La position de recharge peut être déterminée par apprentissage automatique, en particulier par une procédure de commande de mouvements du store jusqu'à une position dans laquelle le rapport surface de panneau de cellules photovoltaïques exposée/longueur de toile déployée est maximisé.The recharging position can be determined by automatic learning, in particular by a blind motion control procedure to a position in which the exposed photovoltaic cell panel surface / deployed fabric length ratio is maximized.
La position de recharge peut être une position de repli du store en cas de vent.The charging position can be a fallback position of the awning in the event of wind.
La position de recharge peut varier en fonction des conditions d'ensoleillement et/ou en fonction de l'orientation des rayons solaires. La toile peut se déplier jusqu'à la position de recharge au cours de l'étape b) sous certaines conditions de déploiement, celles-ci étant prédéfinies automatiquement ou manuellement par un installateur.The recharging position may vary depending on the sun conditions and / or depending on the orientation of the sun's rays. The canvas can unfold to the recharging position during step b) under certain deployment conditions, these being predefined automatically or manually by an installer.
Le procédé selon l'invention régit d'une installation domotique de protection solaire motorisée, comprenant : un actionneur destiné à déployer et replier une toile, comprenant un moteur et un module de commande du moteur, et un panneau de cellules photovoltaïques fixe ou mobile sous l'effet de l'actionneur, destiné à fournir de l'énergie pour recharger une réserve d'énergie électrique alimentant l'actionneur. Le procédé de fonctionnement comprend les étapes automatiques suivantes : a) déplacement du panneau de cellules photovoltaïques ou de la toile jusqu'à une position de recharge dans laquelle le panneau est exposé directement ou par réflexion aux rayons solaires, b) utilisation d'une mesure d'énergie fournie par le panneau pour déterminer un critère d'ensoleillement, c) déploiement de la toile du store si le critère d'ensoleillement dépasse un seuil prédéfini.The method according to the invention governs a motorized solar protection home automation system, comprising: an actuator intended to deploy and fold up a fabric, comprising a motor and an engine control module, and a fixed or mobile photovoltaic cell panel under the effect of the actuator, intended to supply energy to recharge a reserve of electrical energy supplying the actuator. The method of operation comprises the following automatic steps: a) moving the photovoltaic cell panel or the fabric to a charging position in which the panel is exposed directly or by reflection to the sun, b) use of a measurement energy provided by the panel to determine a sun exposure criterion, c) deployment of the awning fabric if the sun exposure criterion exceeds a predefined threshold.
Selon l'invention, une installation domotique de protection solaire motorisée, comprend : - un actionneur destiné à déployer et replier une toile, comprenant un moteur et un module de commande du moteur, et un panneau de cellules photovoltaïques mobile sous l'effet de l'actionneur, destiné à recharger une réserve d'énergie électrique alimentant l'actionneur. Elle est caractérisée en ce qu'elle comprend des moyens matériels et logiciels de mise en œuvre du procédé de fonctionnement défini précédemment.According to the invention, a motorized solar protection home automation system comprises: an actuator intended to deploy and fold up a fabric, comprising a motor and an engine control module, and a mobile photovoltaic cell panel under the effect of actuator, for recharging a reserve of electrical energy supplying the actuator. It is characterized in that it comprises hardware and software means for implementing the operating method defined above.
Les moyens matériels et logiciels peuvent comprendre un moyen de détermination du niveau d'énergie disponible dans la réserve d'énergie et/ou un moyen de détermination de la puissance convertie par le panneau de cellules photovoltaïques.The hardware and software means may comprise a means for determining the energy level available in the energy reserve and / or a means for determining the power converted by the photovoltaic cell panel.

Les figures 8, 9 et 10 sont des schémas respectifs de troisième, quatrième et cinquième modes de réalisation d'une installation de protection solaire fonctionnant selon le procédé objet de l'invention.Figures 8, 9 and 10 are respective diagrams of third, fourth and fifth embodiments of a sun protection system operating according to the method object of the invention.
Un premier mode de réalisation d'installation 101 de protection solaire représenté à la figure 2 est monté sur un mur 102 muni d'un avant-toit 103. Un socle 104 fixé au mur soutient un caisson 105 dans lequel est enroulée une toile 106, représentée en pointillés dans le caisson et en trait plein à l'extérieur du caisson. L'extrémité libre de la toile est fixée à une barre de charge 108, celle-ci étant maintenue par des bras 107 fixés au caisson ou au mur. Les bras sont des bras dépliables sous l'action d'une force élastique assurant la tension de la toile. L'action combinée d'un actionneur (non représenté) et des bras permet le déploiement et le repli de la toile dans le caisson.A first embodiment of solar protection installation 101 shown in FIG. 2 is mounted on a wall 102 provided with an eave 103. A base 104 fixed to the wall supports a caisson 105 in which a web 106 is wound, shown in dashed lines in the box and solid line on the outside of the box. The free end of the fabric is attached to a load bar 108, the latter being held by arms 107 attached to the box or wall. The arms are foldable arms under the action of an elastic force ensuring the tension of the fabric. The combined action of an actuator (not shown) and arms allows the deployment and folding of the fabric in the box.
L'actionneur est muni d'un module de commande (non représenté) et est alimenté par l'intermédiaire d'une réserve d'énergie 1 10 placée dans le caisson ou à proximité de celui-ci. Un panneau de cellules photovoltaïques PV100 est placé sur la barre de charge. Il est relié à la réserve d'énergie notamment par un câble 1 1 1 , le câble passant par exemple le long des bras. Dans cette installation, l'ensemble tube d'enroulement de la toile, toile, barre de charge et bras constitue un store. Le panneau de cellules photovoltaïques est mobile avec la toile.The actuator is provided with a control module (not shown) and is powered via a power reserve 1 10 placed in the box or close to it. A photovoltaic cell panel PV100 is placed on the load bar. It is connected to the energy reserve in particular by a cable 1 1 1, the cable passing for example along the arms. In this installation, the winding tube assembly of the fabric, fabric, load bar and arm constitutes a blind. The photovoltaic cell panel is mobile with the canvas.
L'installation 101 est représentée dans une position dite position de recharge PR100. Cette position est décalée par rapport à une position de fin de course haute FDCH100, ou position de butée, dans laquelle la toile est complètement enroulée ou considérée comme telle. Cette position de fin de course haute peut également correspondre à la position dans laquelle la barre de charge est en contact avec le caisson du store et vient fermer celui-ci. La position de recharge est définie par exemple par une position intermédiaire déterminée ou par une longueur déterminée de déroulement de la toile.The installation 101 is represented in a position called PR100 recharge position. This position is offset with respect to a high end position FDCH100, or stop position, in which the fabric is completely wound or considered as such. This high end position can also correspond to the position in which the load bar is in contact with the awning box and closes the latter. The recharging position is defined for example by a determined intermediate position or by a determined length of unwinding of the fabric.
L'avant-toit 103 est beaucoup plus débordant que dans la figure 1. Il crée une zone d'ombre vis-à-vis des rayons solaires 1 15, représentée par des hachures horizontales, dans laquelle se situe l'installation lorsque le store est dans sa position de fin de course haute.The eave 103 is much more overflowing than in Figure 1. It creates a shadow zone vis-à-vis the sun 1 15, represented by horizontal hatching, in which the installation is located when the blind is in its high end position.
Dans la position de recharge, le panneau est préférentiellement complètement exposé au rayonnement solaire présent. Cependant, il est possible également que seule une partie utile soit exposée (au moins une partie du panneau se trouve hors de l'abri de l'avant-toit ou du balcon, c'est-à-dire hors de la zone d'ombre.In the recharging position, the panel is preferably completely exposed to the solar radiation present. However, it is also possible that only a useful part is exposed (at least part of the panel is outside the shelter of the eave or balcony, that is to say outside the area of shadow.
Le panneau de cellules photovoltaïques placé sur la barre de charge, n'est au moins partiellement hors de cette zone d'ombre que lorsque la barre de charge est déplacée au moins jusqu'à la position de recharge PR100 représentée. Cette position de recharge dépend bien entendu de l'avancée de l 'avant- toit, de la hauteur à laquelle est installé le store par rapport à l'avant-toit et de l'inclinaison des rayons solaires.The photovoltaic cell panel placed on the load bar, is at least partially out of this shadow area only when the load bar is moved at least to the PR100 recharge position shown. This recharging position of course depends on the advance of the eave, the height at which the blind is installed in relation to the eaves and the inclination of the sun's rays.
Le panneau de cellules photovoltaïques étant placé sur la barre de charge, celui-ci génère une faible quantité d'énergie lorsqu'il est situé dans la zone d'ombre. Il est ainsi beaucoup moins performant que lorsqu'il est exposé au rayonnement solaire direct en dehors de la zone d'ombre.The photovoltaic cell panel being placed on the charge bar, it generates a small amount of energy when it is located in the shadow zone. It is thus much less powerful than when it is exposed to direct solar radiation outside the shadow zone.
Toute position dans laquelle le panneau de cellules photovoltaïques est exposé au maximum au rayonnement solaire direct est ainsi une position de performance maximum. En revanche, lorsque le store est déployé, il est plus sensible aux conditions climatiques extérieures (pluie, vent, soleil, température). De plus, il faut éviter qu'un comportement de déploiement automatique de recharge soit considéré comme étrange ou perturbateur par un utilisateur.Any position in which the photovoltaic cell panel is exposed to maximum direct solar radiation is thus a position of maximum performance. On the other hand, when the awning is deployed, it is more sensitive to external climatic conditions (rain, wind, sun, temperature). In addition, it should be avoided that a behavior of automatic deployment of recharging is considered strange or disruptive by a user.
Un capteur solaire 1 16 et un anémomètre 1 17 permettent de tester les conditions climatiques relatives à la présence de vent et de soleil. L'anémomètre peut également se présenter sous la forme d'un capteur de vent fixé à l'installation de store elle-même.A solar collector 1 16 and an anemometer 1 17 make it possible to test the climatic conditions relating to the presence of wind and sun. The anemometer may also be in the form of a wind sensor attached to the blind installation itself.
Un deuxième mode de réalisation d'installation 201 de protection solaire est représenté à la figure 3. La figure 3 reprend les références précédentes relatives à la figure 2, augmentées de 100. Un panneau de cellules photovoltaïques PV200 est placé non pas sur la barre de charge, mais sur la toile à proximité de la barre de charge ; il s'étend par exemple le long de la barre de charge. Il est relié à la réserve d'énergie notamment par un câble 21 1. Sur cette figure, le panneau est volontairement représenté par un trait épais. Cependant, le panneau de cellules photovoltaïques peut être intégré dans la toile, et ne pas nécessairement former de surépaisseur par rapport au reste de la toile.A second embodiment of solar protection installation 201 is shown in FIG. 3. FIG. 3 repeats the previous references relating to FIG. 2, increased by 100. A photovoltaic cell panel PV200 is placed not on the bar of FIG. load, but on the canvas near the load bar; it extends for example along the load bar. It is connected to the energy reserve in particular by a cable 21 1. In this figure, the panel is voluntarily represented by a thick line. However, the panel of Photovoltaic cells can be integrated into the fabric, and do not necessarily form extra thickness compared to the rest of the fabric.
Le panneau de cellules photovoltaïques placé sur ou dans la toile le long de la barre de charge, ne sort de la zone d'ombre créée par l'avant-toit 203 que lorsque la barre de charge est déplacée au moins jusqu'à la position de recharge PR200 représentée.The photovoltaic cell panel placed on or in the fabric along the load bar, only comes out of the shadow zone created by the eave 203 when the load bar is moved at least to the position PR200 charging station shown.
Le panneau de cellules photovoltaïques fixé sur la toile du store n'est exposé aux rayons solaires que lorsque le store est déplacé au moins jusqu'à la position de recharge. Dans cette position de recharge, le panneau est préférentiellement complètement exposé au rayonnement solaire présent. Cependant, il est possible également que seule une partie utile soit exposée. Lorsque la toile est complètement enroulée et dans sa position de fin de course haute FDCH200, aucune énergie n'est générée par le panneau. De même que précédemment, lorsque le store est déployé, il est sensible aux conditions climatiques extérieures (pluie, vent, soleil, température). De plus, il faut éviter qu'un comportement de déploiement automatique de recharge soit considéré comme étrange par un utilisateur. Ceci s'applique également aux modes de réalisation décrits ci-dessous.The photovoltaic cell panel attached to the blind fabric is exposed to sunlight only when the blind is moved at least to the recharging position. In this charging position, the panel is preferably completely exposed to solar radiation present. However, it is also possible that only a useful part is exposed. When the fabric is fully wound and in its high end position FDCH200, no energy is generated by the panel. As before, when the awning is deployed, it is sensitive to external climatic conditions (rain, wind, sun, temperature). In addition, it should be avoided that a behavior of automatic deployment of recharge is considered strange by a user. This also applies to the embodiments described below.
Un troisième mode de réalisation d'installation 301 de protection solaire est représenté à la figure 8. La figure 8 reprend les références précédentes augmentées de 100.A third embodiment of solar protection installation 301 is shown in FIG. 8. FIG. 8 is a reference of the previous references increased by 100.
L'installation 301 de la figure 8 diffère des installations précédemment décrites en ce que le panneau de cellules photovoltaïques PV300 est mobile par rapport au caisson du store, son mouvement n'étant qu'indirectement lié aux mouvements de la toile. En particulier, le panneau de cellules photovoltaïques est lui-même monté sur des bras 309 repliables assez similaires à ceux du store. Ces bras permettent de déplacer le panneau de cellules photovoltaïques d'une première position de repli vers une deuxième position de déploiement dans laquelle le panneau de cellules photovoltaïques est exposé aux rayons solaires.The installation 301 of FIG. 8 differs from the installations previously described in that the photovoltaic cell panel PV300 is movable relative to the box of the blind, its movement being only indirectly related to the movements of the fabric. In particular, the photovoltaic cell panel is itself mounted on arms 309 folding quite similar to those of the blind. These arms make it possible to move the photovoltaic cell panel from a first retracted position to a second deployment position in which the photovoltaic cell panel is exposed to the sun's rays.
Le mouvement du panneau de cellules photovoltaïques vers la deuxième position de déploiement peut être généré sous l'effet de ressorts associés aux bras 309 lorsqu'un effort contraignant le panneau de cellules photovoltaïques dans la première position de repli est relâché. Cet effort peut être l'action d'un électroaimant piloté à partir du module de commande ou plus avantageusement, un élément mécanique de la barre de charge. Ainsi, la simple présence de la barre de charge bloque le panneau dans sa position de repli. Lorsque la barre de charge est déplacée, par déploiement de la toile, cet effort est relâché et le panneau de cellules photovoltaïques se déplie avec la toile vers la position de recharge PR300.The movement of the photovoltaic cell panel to the second deployment position can be generated under the effect of springs associated with the arms 309 when a force constraining the photovoltaic cell panel in the first retracted position is released. This effort can be the action of an electromagnet controlled from the control module or more advantageously, a mechanical element of the load bar. Thus, the mere presence of the load bar blocks the panel in its folded position. When the load bar is moved, by deployment of the fabric, this effort is released and the photovoltaic cell panel unfolds with the fabric to the PR300 recharge position.
Alternativement, le panneau pourrait coulisser le long de glissières, par exemple télescopiques, remplaçant les bras. Des ressorts dans les glissières permettent le déplacement du panneau vers la position de recharge.Alternatively, the panel could slide along slides, for example telescopic, replacing the arms. Springs in the slides allow movement of the panel to the charging position.
Le panneau de cellules photovoltaïques est avantageusement replié lors du mouvement de repli de la toile. Ainsi, la position de déploiement du panneau de cellules photovoltaïques correspond à un déploiement de la toile dans au moins une position de recharge, le panneau de cellules photovoltaïques se trouvant alors exposé aux rayons solaires en dehors de la zone d'ombre créée par l'avant-toit. Un quatrième mode de réalisation d'installation 401 de protection solaire est représenté à la figure 9. La figure 9 reprend les références précédentes augmentées de 100.The photovoltaic cell panel is advantageously folded during the folding movement of the fabric. Thus, the deployment position of the photovoltaic cell panel corresponds to a deployment of the fabric in at least one recharging position, the panel of photovoltaic cells then being exposed to solar rays outside the shadow zone created by the eave. A fourth embodiment of solar protection installation 401 is shown in FIG. 9. FIG. 9 repeats the previous references increased by 100.
L'installation 401 de la figure 9 diffère des installations précédemment décrites en ce que le panneau de cellules photovoltaïques PV400 est monté sur la structure, mais dans une position dans laquelle il ne reçoit pas directement le rayonnement solaire. Ainsi, contrairement aux installations de l'art antérieur utilisant un panneau de cellules photovoltaïques déporté, celui-ci est monté à proximité de l'installation, sans créer de problèmes de câblage. De façon avantageuse, le panneau de cellules photovoltaïques est monté sur un support 409 sous l'avant-toit 403, les cellules étant dirigées du côté de la toile du store.The installation 401 of FIG. 9 differs from the installations previously described in that the photovoltaic cell panel PV400 is mounted on the structure, but in a position in which it does not receive the solar radiation directly. Thus, unlike the prior art installations using a remote photovoltaic cell panel, it is mounted close to the installation, without creating wiring problems. Advantageously, the photovoltaic cell panel is mounted on a support 409 under the eave 403, the cells being directed towards the awning fabric side.
Le panneau de cellules photovoltaïques reçoit les rayons solaires réfléchis par une partie de la toile, lorsque celle-ci est déployée dans sa position de recharge PR400. A cet effet, la toile comprend une partie réfléchissante montée sur la toile ou intégrée dans celle-ci.The photovoltaic cell panel receives the solar rays reflected by a portion of the fabric when it is deployed in its PR400 charging position. For this purpose, the fabric comprises a reflective portion mounted on the fabric or integrated therein.
Un cinquième mode de réalisation d'installation 501 de protection solaire est représenté à la figure 10. La figure 10 reprend les références précédentes augmentées de 100. Le mode de réalisation de la figure 10 est très proche du précédent. La surface réfléchissante est celle d'un miroir par exemple monté sur la barre de charge et ainsi distincte de la toile. Ce miroir peut être monté basculant pour se ranger contre le caisson du store lorsque la toile est repliée dans sa position de fin de course haute FDCH500 et se repositionner de manière à réfléchir les rayons solaires vers le panneau lorsque la toile est dépliée dans sa position de recharge PR500. Ce mode de réalisation permet d'utiliser un panneau de cellules photovoltaïques plus petit, les rayons solaires pouvant être réfléchis et concentrés vers la surface du panneau de cellules photovoltaïques.A fifth embodiment of the solar protection installation 501 is shown in FIG. 10. FIG. 10 shows the previous references increased by 100. The embodiment of FIG. 10 is very close to the previous one. The reflecting surface is that of a mirror for example mounted on the load bar and thus separate from the fabric. This mirror can be mounted to tilt to store against the awning box when the canvas is folded into its high end position FDCH500 and reposition to reflect the sunlight to the panel when the canvas is unfolded in its position. PR500 recharge. This embodiment makes it possible to use a smaller photovoltaic cell panel, the solar rays being able to be reflected and concentrated towards the surface of the photovoltaic cell panel.
Dans les cinq modes de réalisation, le module de commande permet de piloter l'alimentation du moteur pour manœuvrer la toile du store. Le module de commande est en liaison avec tout moyen capteur utile à la mise en œuvre du procédé de fonctionnement objet de l'invention, comme par exemple un capteur solaire et un anémomètre. Le procédé prend en compte des critères, notamment des critères fournis par les moyens capteur, de manière à optimiser l'énergie disponible pour l'actionnement du store et la protection de celui-ci, sans créer un comportement vécu, par l'utilisateur, comme perturbateur.In the five embodiments, the control module makes it possible to control the power supply of the motor to maneuver the fabric of the blind. The control module is connected to any sensor means that is useful for implementing the operating method that is the subject of the invention, such as for example a solar collector and an anemometer. The method takes into account criteria, including criteria provided by the sensor means, so as to optimize the energy available for actuating the blind and the protection thereof, without creating a behavior experienced by the user, as disruptive.

Les moyens logiciels peuvent comprendre des programmes d'ordinateur.The software means may include computer programs.
Le procédé de fonctionnement de l'installation peut aussi être vu comme un procédé de commande automatique de l'installation dans la mesure où il met en œuvre des manœuvres automatiques de la toile de store. Un premier mode d'exécution du procédé de fonctionnement selon l'invention est décrit ci-après en référence à la figure 4.The operating method of the installation can also be seen as a method of automatic control of the installation insofar as it implements automatic maneuvers of the blind fabric. A first embodiment of the operating method according to the invention is described below with reference to FIG. 4.
Dans une étape E1 , le store est replié et dans un mode de fonctionnement dit mode de recharge, c'est-à-dire que l'installation cherche à recharger sa réserve d'énergie. La position repliée est de manière générale la position dans laquelle le store se trouve le plus couramment.In a step E1, the blind is folded and in an operating mode said charging mode, that is to say that the installation seeks to recharge its energy reserve. The folded position is generally the position in which the blind is most commonly.
Au cours d'une étape E2, la présence de vent est testée. En effet, il est préférable de n'intervenir dans la gestion du store, notamment chercher à recharger la réserve d'énergie, qu'en l'absence de vent (ou lorsque la vitesse du vent est inférieure à un seuil de précaution). En cas de présence de vent, aucune action n'est mise en œuvre (retour à l'étape E1 ). Le même type de test peut être mis en œuvre selon un autre paramètre climatique, notamment un paramètre surveillé pour assurer la sécurité de l'installation.During a step E2, the presence of wind is tested. Indeed, it is better not to intervene in the management of the blind, in particular to seek to recharge the energy reserve, than in the absence of wind (or when the speed of the wind is lower than a threshold of precaution). In case of presence of wind, no action is implemented (return to step E1). The same type of test can be implemented according to another climatic parameter, especially a parameter monitored to ensure the safety of the installation.
Dans le cas contraire, à intervalles prédéfinis au cours d'une étape E3, le module de commande de l'actionneur teste si la quantité d'énergie disponible dans la réserve d'énergie est suffisante (supérieure à un premier seuil) et/ou si l'apport d'énergie par le panneau de cellules photovoltaïques dans la position repliée du store est suffisant pour la recharge de la réserve d'énergie (supérieur à un deuxième seuil). Si tel est le cas, le procédé boucle sur l'étape E1 et aucune manœuvre n'est mise en œuvre. Le store reste replié.In the opposite case, at predetermined intervals during a step E3, the control module of the actuator tests whether the quantity of energy available in the energy reserve is sufficient (greater than a first threshold) and / or if the energy input by the photovoltaic cell panel in the folded position of the blind is sufficient for recharging the energy reserve (greater than a second threshold). If this is the case, the process loops on step E1 and no maneuver is implemented. The blind remains folded.
Si le niveau d'énergie n'est pas suffisant et/ou si l'apport d'énergie par le panneau de cellules photovoltaïques est faible (inférieur au deuxième seuil), le procédé poursuit vers une étape E4, au cours de laquelle l'actionneur déploie le store jusqu'à une position prédéterminée de recharge PFM 00 ; PR200 ; PR300 ; PR400 ; PR500, dans laquelle le panneau de cellules photovoltaïques est exposé au rayonnement direct. Le store est maintenu dans cette position de recharge tant que le vent reste absent et que le niveau d'énergie n'est pas complet ou n'a pas atteint un seuil, et/ou que l'apport d'énergie par le panneau photovoltaïque retombe sous le deuxième seuil.If the energy level is not sufficient and / or if the energy input by the photovoltaic cell panel is small (less than the second threshold), the process proceeds to a step E4, during which the actuator deploys the blind to a predetermined charging position PFM 00; PR200; PR300; PR400; PR500, in which the photovoltaic cell panel is exposed to direct radiation. The blind is maintained in this charging position as long as the wind is absent and the energy level is not complete or has not reached a threshold, and / or the energy input by the photovoltaic panel falls under the second threshold.
La fonction de test de vent peut également ne pas être considérée comme une fonction critique pour ce procédé. En effet, le store déployé dans sa position de recharge peut offrir peu de prise au vent et se trouver protégé du vent par l'avant-toit. L'étape E2 est donc facultative.The wind test function may also not be considered a critical function for this process. Indeed, the awning deployed in its recharging position can offer little grip wind and be protected from the wind by the eave. Step E2 is therefore optional.
Un deuxième mode d'exécution du procédé de fonctionnement selon l'invention est décrit ci-après en référence à la figure 5.A second embodiment of the operating method according to the invention is described below with reference to FIG.
Selon cet ordinogramme, dans une étape F1 , le store est replié et dans le mode de fonctionnement dit mode de recharge.According to this flow chart, in a step F1, the blind is folded and in the operating mode said charging mode.
Au cours d'une étape F2, le module de commande de l'actionneur teste si la quantité d'énergie disponible dans la réserve d'énergie est suffisante. Si tel est le cas, le procédé boucle sur l'étape F1 et aucune action n'est mise en œuvre. Le store reste replié.During a step F2, the control module of the actuator tests whether the amount of energy available in the energy reserve is sufficient. If this is the case, the process loops on step F1 and no action is implemented. The blind remains folded.
Dans le cas contraire, le module de commande teste la présence de soleil direct dans une étape F3. Cette étape F3 dépend de la présence d'un capteur solaire exposé au soleil direct.In the opposite case, the control module tests the presence of direct sun in a step F3. This step F3 depends on the presence of a solar collector exposed to direct sunlight.
Si la présence de soleil est détectée supérieure à un premier seuil si , l'actionneur déploie le store jusqu'à une position prédéterminée de recharge (étape F4), dans laquelle le panneau de cellules photovoltaïques est exposé au rayonnement direct. Le niveau d'énergie emmagasiné dans la réserve d'énergie augmente alors progressivement.If the presence of sun is detected greater than a first threshold if the actuator deploys the blind to a predetermined charging position (step F4), in which the cell panel photovoltaic is exposed to direct radiation. The level of energy stored in the energy reserve then increases gradually.
Le procédé boucle alors vers l'étape F2 de test du niveau d'énergie. Lorsque celui-ci est suffisant, le module de commande actionne un repli du store depuis la position de recharge (retour à l'étape F1 ). Sinon, le store reste dans la position de recharge tant que les paramètres climatiques (vent, soleil) conservent les mêmes valeurs ou des valeurs semblables.The process then loops to step F2 of testing the energy level. When it is sufficient, the control module actuates a folding of the blind from the charging position (return to step F1). Otherwise, the blind stays in the charging position as long as the climatic parameters (wind, sun) keep the same values or similar values.
Dans le cas où la présence de soleil direct est mesurée inférieure à un deuxième seuil s2 (étape F5), le procédé boucle vers l'étape F1. Aucun mouvement n'est actionné. Le store reste replié. Le seuil d'éclairement est trop faible pour avoir un intérêt pour la recharge de l'installation. Le seuil s2 est de préférence dépendant d'un paramètre, comme par exemple dépendant de la charge de la réserve d'énergie électrique ou de la capacité du panneau photovoltaïque à charger cette réserve. Evidemment, plus la charge de la réserve est faible, plus la valeur du seuil s2 est basse. De même, plus la capacité de charge du panneau est faible, plus la valeur du seuil s2 est basse.In the case where the presence of direct sun is measured lower than a second threshold s2 (step F5), the process loops to step F1. No movement is activated. The blind remains folded. The illumination threshold is too low to have an interest in recharging the installation. The threshold s 2 is preferably dependent on a parameter, such as for example depending on the load of the reserve of electrical energy or the capacity of the photovoltaic panel to charge this reserve. Obviously, the lower the charge of the reserve, the lower the value of the threshold s2. Similarly, the lower the load capacity of the panel, the lower the value of the threshold s2.
Si le niveau de soleil est supérieur au deuxième seuil s2, le procédé se poursuit par l'étape F4 de déploiement du store jusqu'à la position de recharge. Ainsi, même dans des conditions d'éclairement moyen (ciel blanc, présence de nuages), le store est placé dans la position préférentielle de recharge en dehors de la zone d'ombre créée par la présence de l'avant-toit.If the sun level is greater than the second threshold s2, the method continues with the step F4 of deployment of the blind to the recharging position. Thus, even in conditions of average illumination (white sky, presence of clouds), the blind is placed in the preferential position of recharge outside the shadow zone created by the presence of the eave.
Un troisième mode d'exécution du procédé de fonctionnement selon l'invention est décrit ci-après en référence à la figure 6. Dans une étape G1 , le store est replié et dans le mode de fonctionnement dit mode de recharge. A intervalles prédéfinis au cours d'une étape G2, le module de commande de l'actionneur teste si la quantité d'énergie disponible dans la réserve d'énergie est suffisante et/ou si l'apport d'énergie par le panneau de cellules photovoltaïques dans la position repliée du store est suffisant (supérieur à un deuxième seuil). Si tel est le cas, le procédé boucle sur l'étape G1 et aucune action n'est mise en œuvre. Le store reste replié.A third embodiment of the operating method according to the invention is described below with reference to FIG. In a step G1, the blind is folded and in the operating mode said charging mode. At predetermined intervals during a step G2, the control module of the actuator tests whether the quantity of energy available in the energy reserve is sufficient and / or if the energy supply by the cell panel photovoltaic in the folded position of the blind is sufficient (greater than a second threshold). If this is the case, the process loops on step G1 and no action is implemented. The blind remains folded.
Si le niveau d'énergie n'est pas suffisant et/ou si l'apport d'énergie par le panneau de cellules photovoltaïques est faible (inférieur au deuxième seuil), le procédé poursuit vers une étape G3, au cours de laquelle l'actionneur déploie le store jusqu'à une position prédéterminée de recharge, dans laquelle le panneau de cellules photovoltaïques est exposé au rayonnement direct.If the energy level is not sufficient and / or if the energy input by the photovoltaic cell panel is small (less than the second threshold), the process proceeds to a step G3, during which the actuator deploys the blind to a predetermined recharge position, wherein the photovoltaic cell panel is exposed to direct radiation.
Le module de commande lui-même teste la présence de soleil direct au cours d'une étape G4: en effet, si un rayonnement solaire direct est présent, le niveau d'énergie emmagasiné dans la réserve d'énergie augmente progressivement de manière significative. Le test de présence de soleil est réalisé alors directement par l'intermédiaire du panneau de cellules photovoltaïques et du module de commande. Cette étape G4 s'apparente à une mesure de l'évolution d'énergie emmagasinée (ou produite par le panneau de cellules photovoltaïques).The control module itself tests the presence of direct sun during a step G4: indeed, if direct solar radiation is present, the energy level stored in the energy reserve increases gradually significantly. The sun test is then performed directly via the photovoltaic cell panel and the control module. This step G4 is similar to a measurement of the energy evolution stored (or produced by the panel of photovoltaic cells).
L'étape G4 se poursuit tant que le niveau d'énergie augmente. Le store peut être replié lorsque le niveau de charge maximum est atteint ou lorsqu'un seuil est dépassé à la hausse. La récurrence des tests de niveau d'énergie de l'étape G2 peut alors être diminuée. En présence de soleil direct ou diffusé par des surfaces réfléchissantes, tel que dans une situation de ciel blanc, le niveau d'énergie emmagasiné en position de recharge est significatif. Tant qu'il représente une énergie non négligeable, par exemple dans le cas d'un store dont le panneau de cellules photovoltaïques est fixé sur la toile, celle-ci étant complètement masquée lorsque le store est enroulé, le module de commande maintient alors le déploiement du store dans la position de recharge. Ainsi, même dans des conditions d'éclairement moyen (ciel blanc, présence de nuages), le store est maintenu dans la position préférentielle de recharge en dehors de la zone d'ombre créée par la présence de l'avant-toit.Step G4 continues as the energy level increases. The blind can be folded when the maximum load level is reached or when a threshold is exceeded. The recurrence of the energy level tests of step G2 can then be decreased. In the presence of direct sun or scattered by reflective surfaces, such as in a situation of white sky, the energy level stored in the recharging position is significant. As long as it represents a significant energy, for example in the case of a blind whose photovoltaic cell panel is fixed on the canvas, the latter being completely hidden when the blind is wound, the control module then maintains the deployment of the blind in the charging position. Thus, even in conditions of average illumination (white sky, presence of clouds), the blind is maintained in the preferred position of recharge outside the shadow zone created by the presence of the eave.
Lorsque le taux d'énergie emmagasiné est mesuré en dessous d'une certaine valeur de seuil (étape G5), le store est de nouveau enroulé jusqu'à sa position de fin de course haute. Les conditions d'éclairement s'avèrent alors insuffisantes (ciel gris, nuit).When the stored energy rate is measured below a certain threshold value (step G5), the blind is rolled up again to its upper end position. The lighting conditions are then insufficient (gray sky, night).
La durée entre deux tests de niveau d'énergie peut alors être réduite pour économiser l'énergie disponible. Une durée normale peut être réinstaurée lorsqu'un ordre de commande est passé.The time between two energy level tests can then be reduced to save the available energy. A normal time can be reinstated when a command order is placed.
La position de recharge PFM 00, PR200, PR300, PR400, PR500 peut être mémorisée suite à un réglage de l'installateur ou par apprentissage automatique. Une procédure d'apprentissage automatique mise en œuvre dans une installation comportant un capteur de soleil externe exposé au soleil direct est décrite ci-après en référence à la figure 7.The PFM 00, PR200, PR300, PR400, PR500 recharge position can be memorized following an installer setting or by automatic learning. An automatic learning procedure implemented in an installation comprising an external sun sensor exposed to direct sunlight is described hereinafter with reference to FIG. 7.
Au cours d'une première étape H1 lors de l'installation ou de manière automatique tant qu'aucune position de recharge n'est en mémoire, la présence de soleil direct est détectée par le capteur déporté 1 16, 216, 316, 416, 516. Un ordre de déploiement du store est alors émis au cours d'une étape H2 et le store commence à se déployer, permettant ainsi de commencer à exposer le panneau de cellules photovoltaïques aux rayons de soleil. Ce mouvement est stoppé lors de l'étape H3, alors qu'une grandeur électrique est mesurée (courant, tension ou autre) en provenance du panneau de cellules photovoltaïques. Cet arrêt peut être déclenché par la détection d'une valeur de grandeur électrique supérieure à un seuil prédéfini. En particulier, lorsque le panneau de cellules photovoltaïques est exposé au moins partiellement aux rayons solaires, sa production en énergie devient non nulle. La grandeur électrique mesurée traduit cette production d'énergie sensible. La position de recharge correspond alors au moins au positionnement de la toile de store telle qu'une surface utile du panneau photovoltaïque est exposée.During a first step H1 during installation or automatically as long as no charging position is in memory, the presence of direct sun is detected by the remote sensor 1 16, 216, 316, 416, 516. An order of deployment of the blind is then issued during a step H2 and the blind starts to unfold, thus allowing start exposing the panel of photovoltaic cells to the sun's rays. This movement is stopped during step H3, while an electrical quantity is measured (current, voltage or other) from the photovoltaic cell panel. This stop can be triggered by the detection of an electric magnitude value greater than a predefined threshold. In particular, when the photovoltaic cell panel is exposed at least partially to solar rays, its energy production becomes non-zero. The measured electrical quantity reflects this production of sensible energy. The recharging position then corresponds at least to the positioning of the blind fabric such that a useful surface of the photovoltaic panel is exposed.
Au cours de l'étape H4, la position courante du store, ou sa position d'arrêt est mesurée et mise en mémoire comme position de recharge. En effet, lorsque le store est déployé jusqu'à cette position minimale en présence de soleil direct, la production d'énergie par la partie du panneau de cellules photovoltaïques exposée est considérée comme suffisante.During step H4, the current position of the blind, or its stopping position, is measured and stored as a charging position. Indeed, when the blind is deployed to this minimum position in the presence of direct sun, energy production by the portion of the photovoltaic cell panel exposed is considered sufficient.
Dans un autre mode de réalisation, la position de recharge n'est pas définie de manière fixe.In another embodiment, the recharge position is not fixedly defined.
En cas de soleil direct détecté par un capteur déporté, le déploiement a lieu jusqu'à une mesure significative relative à la production d'énergie par le panneau de cellules photovoltaïques. La position de recharge peut ainsi être déterminée par la détection d'une variation de tension ou de courant issus du panneau de cellules photovoltaïques supérieurs à un seuil. Cette position de recharge correspond au moins au positionnement de la toile de store telle qu'une surface utile du panneau photovoltaïque est exposée. Une fois cette variation détectée, la position de recharge peut être déterminée par une poursuite du déploiement pendant une course donnée (déploiement de 30 cm ou déroulement d'un tour d'axe d'enroulement).In case of direct sun detected by a remote sensor, the deployment takes place up to a significant measurement relative to the production of energy by the panel of photovoltaic cells. The recharging position can thus be determined by the detection of a variation of voltage or current coming from the panel of photovoltaic cells greater than a threshold. This charging position corresponds at least to the positioning of the awning fabric such that a useful surface of the photovoltaic panel is exposed. Once this variation has been detected, the recharge position can be determined by further deployment during a given stroke (30 cm deployment or unwinding of a winding axis revolution).
D'autres méthodes de détermination d'une position de recharge fixe ou variable peuvent être également envisagées. Les différents modes d'exécution du procédé ont par ailleurs été décrits en référence au store mobile avec le panneau. Cependant, ils sont également applicables aux modes d'exécution des figures 8 à 10.Other methods for determining a fixed or variable recharge position can also be envisaged. The various embodiments of the method have also been described with reference to the movable blind with the panel. However, they are also applicable to the embodiments of FIGS. 8 to 10.
Dans les différents modes d'exécution du procédé, le déplacement du panneau ou de la toile de la position repliée vers la position de recharge peut ne nécessiter qu'une très faible énergie. En effet, ce déplacement peut être entraîné par les ressorts des bras et il peut donc être nécessaire au niveau de l'actionneur que de libérer un frein. Néanmoins, l'exécution de ce déplacement peut tout de même être conditionnée au fait que la réserve d'énergie soit suffisante pour assurer ultérieurement un repli du panneau ou de la toile depuis la position de recharge.In the various embodiments of the method, moving the panel or canvas from the folded position to the recharging position may require only very low energy. Indeed, this movement can be driven by the springs of the arms and it may be necessary at the actuator to release a brake. Nevertheless, the execution of this displacement can still be conditioned to the fact that the energy reserve is sufficient to subsequently provide a fold of the panel or canvas from the recharging position.
Le store peut également être commandé vers une position dite intermédiaire prédéfinie ou choisie par l'utilisateur et indépendante de la position de recharge.The blind can also be controlled to an intermediate position predefined or chosen by the user and independent of the charging position.
Dans différents modes d'exécution, on détermine la puissance pouvant être convertie en énergie électrique par le panneau photovoltaïque. Ceci peut être assuré par différents moyens. Notamment, cette détermination peut être faite par mesure de la tension ou du courant produit aux bornes du panneau, ou par mesure de l'éclairement puis utilisation d'une table de correspondance entre la valeur d'éclairement et la puissance pouvant être convertie en énergie électrique. Dans les différents modes d'exécution et variantes, le déploiement de la toile jusqu'à la position de recharge peut se faire sous certaines conditions de déploiement, ces conditions pouvant être prédéfinies automatiquement ou manuellement par un installateur. Par exemple, ces conditions peuvent porter sur le type d'installation domotique incorporant la toile, sur l'implantation du panneau de cellules photovoltaïques sur l'installation, sur l'implantation de l'installation sur le bâtiment, notamment sa position et son orientation. Ces conditions peuvent notamment déterminer ou intervenir dans la détermination de la séquence des actions de déploiement jusqu'à la position de recharge.In different embodiments, the power that can be converted into electrical energy by the photovoltaic panel is determined. This can be done by various means. In particular, this determination can be made by measuring the voltage or current produced at the terminals of the panel, or by measuring the illumination and then using a correspondence table between the illumination value and the power that can be converted into energy. electric. In the various embodiments and variants, the deployment of the canvas to the charging position can be done under certain deployment conditions, these conditions can be predefined automatically or manually by an installer. For example, these conditions may relate to the type of home automation system incorporating the fabric, the installation of the photovoltaic cell panel on the installation, the installation of the installation on the building, in particular its position and its orientation. . These conditions can in particular determine or intervene in the determination of the sequence of deployment actions to the charging position.
La position de recharge peut être utilisée également indépendamment du critère de recharge de la réserve d'énergie et en l'absence de capteur solaire lié à l'installation, comme position de déploiement permettant de détecter la présence de soleil. Ainsi, l'invention porte également sur un procédé de détermination et/ou de mesure d'un critère ou paramètre d'ensoleillement. Le procédé comprend alors une étape de déplacement du panneau de cellules photovoltaïques ou de la toile jusqu'à une position de recharge prédéfinie dans laquelle le panneau est, en cas d'ensoleillement, exposé, directement ou par réflexion, aux rayons solaires et une étape d'utilisation d'une mesure d'énergie fournie par le panneau pour déterminer le critère ou paramètre d'ensoleillement.The recharging position can also be used regardless of the criterion of recharging the energy reserve and in the absence of a solar sensor linked to the installation, as deployment position for detecting the presence of sun. Thus, the invention also relates to a method for determining and / or measuring a criterion or parameter of sunshine. The method then comprises a step of moving the photovoltaic cell panel or the fabric to a predefined recharging position in which the panel is, in case of sunshine, exposed, directly or by reflection, to the sun's rays and a step using an energy measurement provided by the panel to determine the criterion or sun setting.
Le procédé de détermination et/ou de mesure d'un critère ou paramètre d'ensoleillement peut être intégré à un procédé de fonctionnement d'une installation domotique de protection solaire motorisée dans laquelle on commande en outre un déploiement d'une toile de store en fonction du critère ou paramètre d'ensoleillement déterminé. The method of determining and / or measuring a criterion or parameter of sunshine can be integrated into a method of operation of a motorized solar protection home automation system in which a deployment of a blind fabric is also controlled. depending on the criterion or parameter of sunshine determined.
