Description

L'invention se rapporte au domaine des protections solaires et en particulier à la protection de celles-ci contre les effets du vent. Elle concerne en particulier des procédés d'initialisation pour la commande d'une installation comprenant au moins un dispositif motorisé présentant un élément mobile de fermeture, d'occultation ou de protection solaire, chaque dispositif motorisé étant muni d'un capteur de mesure des effets du vent sur son élément mobile. Elle concerne également des procédés de commande d'une installation initialisée selon le procédé précédent et des installations pour la mise en oeuvre de ces procédés.The invention relates to the field of solar protection and in particular to the protection thereof against the effects of wind. It relates in particular to initialization methods for controlling an installation comprising at least one motorized device having a movable closure element, occultation or sun protection, each motorized device being provided with a sensor for measuring the effects. wind on its moving element. It also relates to control methods of an installation initialized according to the preceding method and facilities for carrying out these methods.

II est de plus en plus courant de munir les protections solaires de type stores de terrasse de capteurs de vent, soleil, pluie, qui permettent à la fois leur automatisation et leur protection contre les effets néfastes des évènements climatiques.It is more and more common to provide the solar protection type terrace awnings of wind, sun, and rain sensors, which allow both their automation and their protection against the harmful effects of climatic events.

En particulier, les bourrasques de vent peuvent endommager sérieusement la structure d'un écran ou la structure porteuse et/ou causer d'importants dégâts. Divers capteurs de vent de plusieurs types, tels que les anémomètres, les accéléromètres, les détecteurs de couple ou de rotation du tube d'enroulement, sont connus.In particular, wind squalls can seriously damage the structure of a screen or the supporting structure and / or cause significant damage. Various wind sensors of several types, such as anemometers, accelerometers, torque detectors or winding tube rotors, are known.

Les accéléromètres et les détecteurs de couple ou de rotation du tube d'enroulement intégrés à la structure du store sont les plus représentatifs des efforts dus au vent, subis par l'écran. En effet, dans le cas des anémomètres par exemple, il n'est possible de mesurer qu'une vitesse de vent, en une zone déterminée. L'anémomètre est souvent placé sur une façade de bâtiment ou sur un toit, il est parfois commun pour un ensemble de protections solaires. De ce fait, les valeurs mesurées ne sont pas toujours représentatives des efforts qui sont exercés sur l'écran. En revanche, l'inconvénient majeur des capteurs directement intégrés. à la structure de l'écran est l'incapacité à fournir une information sur l'état du vent une fois l'écran rentré.The accelerometers and the winding tube torque or rotation detectors integrated into the blind structure are the most representative of the forces due to the wind, experienced by the screen. Indeed, in the case of anemometers for example, it is possible to measure only a wind speed, in a specific area. The anemometer is often placed on a building facade or on a roof, it is sometimes common for a set of solar protections. As a result, the measured values are not always representative of the forces exerted on the screen. On the other hand, the major disadvantage of directly integrated sensors. the structure of the screen is the inability to provide information on the condition of the wind once the screen returned.

II est donc nécessaire de faire un ou plusieurs essais de déroulement de l'écran, notamment lorsque celui-ci a été replié suite à une bourrasque de vent, pour savoir si la force du vent est à nouveau compatible avec une position déployée de l'écran. Cette solution est inconfortable pour l'utilisateur, d'autant plus que des temporisations sont généralement appliquées pour interdire tout déroulement après la détection d'un certain seuil de vent.It is therefore necessary to make one or more screen unwinding tests, especially when it has been folded following a wind squall, to know if the wind force is again compatible with a deployed position of the screen. This solution is uncomfortable for the user, especially since delays are generally applied to prohibit any progress after the detection of a certain wind threshold.

On connaît de la demande EP 1 134 508 une installation gérant automatiquement la climatisation de locaux. Cette installation génère un modèle de comportement des différents équipements électriques liés à la climatisation (chauffage, ventilation, etc.) en fonction de prévisions météorologiques régionales et locales, de données mesurées et de seuils. Le modèle de comportement est corrigé par les différentes données et leur comparaison.Demand is known EP 1 134 508 an installation automatically managing the air conditioning of premises. This installation generates a model of the behavior of the various electrical equipment related to air conditioning (heating, ventilation, etc.) according to regional and local weather forecasts, measured data and thresholds.

Les signaux issus de ces capteurs ne servent qu'à commander l'enroulement du store.

L'invention propose en particulier un procédé d'initialisation permettant d'une part d'améliorer la protection des écrans ou éléments mobiles contre les effets du vent par une détection précise des conditions météorologiques à risque et, d'autre part, de permettre la détection des conditions météorologiques lorsque l'élément mobile est replié afin d'autoriser ou non son déploiement.The object of the invention is to provide, for the control of an installation, means to overcome the drawbacks mentioned above and to improve the methods known from the prior art. The invention proposes in particular an initialization method making it possible, on the one hand, to improve the protection of screens or mobile elements against the effects of the wind by accurately detecting the weather conditions at risk and, on the other hand, to enable the detection of the weather conditions when the mobile element is folded in order to allow or not its deployment.

L'installation 1, représentée, comprend principalement trois dispositifs 7a1, 7a2, 7b comprenant chacun un élément mobile 2i (2a1, 2a2, 2b) de fermeture, d'occultation ou de protection solaire. Ces éléments mobiles peuvent être déplacés dans un sens de déploiement ou dans un sens de repli grâce à des actionneurs électriques 5i (5a1, 5a2, 5b) équipant les dispositifs. Les dispositifs motorisés 7ai (7a1, 7a2) et 7b sont par exemple des stores ou des volets roulants. Les dispositifs motorisés 7ai sont munis de capteurs d'efforts 3i (3a1, 3a2) permettant de détecter les efforts subis par les éléments mobiles et provoqués par le vent. Ces capteurs consistent par exemple en des capteurs de couple exercé sur le tambour d'enroulement de l'élément mobile. Ces capteurs sont de préférence embarqués sur la structure de l'élément mobile ou intégrés à la structure ou à l'actionneur. Ils sont capables de mesurer des déplacements, des vibrations ou des contraintes appliqués à l'élément mobile ou à son actionneur et générés par le vent.The installation 1, shown, mainly comprises three devices 7a1, 7a2, 7b each comprising a movable element 2i (2a1, 2a2, 2b) closing, occultation or sun protection. These movable elements can be moved in a deployment direction or in a fallback direction by means of electric actuators 5i (5a1, 5a2, 5b) fitted to the devices. The motorized devices 7ai (7a1, 7a2) and 7b are example of blinds or shutters. The motorized devices 7ai are provided with force sensors 3i (3a1, 3a2) for detecting the forces experienced by the moving elements and caused by the wind. These sensors consist for example of torque sensors exerted on the winding drum of the movable element. These sensors are preferably embedded on the structure of the movable element or integrated into the structure or the actuator. They are able to measure displacements, vibrations or stresses applied to the moving element or its actuator and generated by the wind.

L'installation 1 comprend également un dispositif 4 de mesure de la vitesse du vent tel qu'un anémomètre. Celui-ci envoie des informations de vitesse du vent à l'unité de commande par exemple par le biais d'une liaison par ondes radioélectriques. L'unité de commande peut en fonction de cette information générer et émettre un ordre de commande de certains ou de l'ensemble des dispositifs motorisés 7ai, 7b. Le dispositif 4 de mesure de vitesse de vent est placé dans l'environnement global des éléments mobiles par exemple sur le toit ou sur une façade du bâtiment. La mesure de vitesse du vent peut également être fournie par un serveur extérieur, de type station météorologique locale.The various motorized devices 7ai, 7b are controlled via a control unit 6. The control commands issued by the control unit 6 have for example the form of radio waves. The control commands are for example issued by a mobile remote control operated by a user towards the control unit and then returned to the various devices. The command orders issued by nomadic remote controls can also be received directly by the motorized devices 7ai, 7b.

The device 4 for measuring wind speed is placed in the global environment of the moving elements, for example on the roof or on a facade of the building. The wind speed measurement may also be provided by an external server, such as a local weather station.

Dans un mode de réalisation non représenté, les différents capteurs 3i et le dispositif de mesure de vitesse du vent 4 communiquent directement avec les actionneurs 5 des différents dispositifs motorisés 7ai. Dans ce cas, les signaux transmis aux actionneurs sont des ordres de commande et chaque dispositif comprend sa propre carte de commande du déplacement de son élément mobile.In an embodiment that is not shown, the various sensors 3i and the wind speed measuring device 4 communicate directly with each other. with the actuators 5 of the various motorized devices 7ai. In this case, the signals transmitted to the actuators are control commands and each device comprises its own control card of the displacement of its mobile element.

La mesure de la vitesse du vent à proximité des dispositifs motorisés 7ai, 7b apporte une information permanente sur la présence ou non de vent, ceci quelle que soit la position de l'élément mobile. Un seul dispositif de mesure de vitesse de vent peut être utilisé pour plusieurs dispositifs. En revanche, la mesure n'est pas toujours pertinente puisqu'elle n'est pas faite à l'endroit précis où se trouve l'élément mobile. De plus, la relation entre la mesure de la vitesse du vent et ses effets sur les éléments mobiles n'est pas toujours évidente à déterminer.The measurement of the wind speed near the motorized devices 7ai, 7b provides permanent information on the presence or absence of wind, regardless of the position of the movable element. A single wind speed measuring device can be used for several devices. However, the measurement is not always relevant since it is not made at the precise location where the mobile element is located. In addition, the relationship between the measurement of wind speed and its effects on moving parts is not always obvious to determine.

La mesure des effets du vent, faite directement sur l'élément mobile, permet d'obtenir une protection très précise, adaptée à chaque élément mobile. Par contre, une fois l'élément mobile replié, la mesure des effets du vent n'est plus possible et il n'y a aucun moyen de savoir si l'élément mobile peut être déroulé en toute sécurité.The measurement of the effects of the wind, made directly on the movable element, makes it possible to obtain a very precise protection adapted to each mobile element. On the other hand, once the movable element is folded, the measurement of the effects of the wind is no longer possible and there is no way of knowing whether the mobile element can be unrolled safely.

Dans le cas d'un élément mobile replié selon l'invention, la mesure de vitesse du vent est disponible et est utilisée pour déterminer si le déploiement de l'élément mobile doit ou non être autorisé.In the case of a folded mobile element according to the invention, the wind speed measurement is available and is used to determine whether or not the deployment of the mobile element is allowed.

Dans le cas d'un élément mobile déployé, la mesure de vitesse du vent ainsi que la mesure des effets du vent sont disponibles. La mesure des effets du vent peut alors être prioritaire. La mesure de la vitesse du vent peut venir également en complément pour assurer une tendance de vent. Eventuellement, celle-ci peut influer sur les seuils de repli du vent dans un procédé de commande dans lequel la mesure des effets du vent est utilisée pour valider un ordre de repli de l'élément mobile.In the case of a deployed mobile element, the wind speed measurement and the wind effect measurement are available. Measuring the effects of wind can then be a priority. The measurement of the wind speed can also come in addition to ensure a wind trend. Optionally, this can influence the wind fall thresholds in a control method in which the wind effect measurement is used to validate a folding order of the movable element.

Pour initialiser une telle installation, on la fait basculer dans un mode d'initialisation puis on enregistre, pour chaque dispositif motorisé 7ai, une valeur seuil d'effets du vent WEi permettant, lorsque le capteur 3i de mesure des effets du vent mesure une valeur supérieure à cette valeur seuil, de valider une action de repli de l'élément mobile 2i. De même, on enregistre, pour chaque dispositif motorisé 7ai, une valeur seuil de vitesse du vent WS1i permettant, lorsque l'installation mesure une vitesse du vent inférieure à cette valeur seuil, de valider une action de déploiement de l'élément mobile. Ces valeurs seuil peuvent être enregistrées dans une mémoire de l'unité de commande 6 de l'installation, dans une mémoire du dispositif de mesure de vitesse de vent 4 et/ou dans une mémoire au niveau de chacun des dispositifs motorisés 7ai. On sort ensuite du mode d'initialisation. L'installation ainsi initialisée est alors opérationnelle.To initialize such an installation, it is switched to an initialization mode and then recorded, for each motorized device 7ai, a wind effect threshold value WEi allowing, when the wind measurement sensor 3i measures a value above this threshold value, to validate a folding action of the movable element 2i. Similarly, for each motorized device 7ai, a wind speed threshold value WS1i is recorded which makes it possible, when the installation measures a wind speed below this threshold value, to validate a deployment action of the mobile element. These threshold values can be recorded in a memory of the control unit 6 of the installation, in a memory of the wind speed measuring device 4 and / or in a memory at each of the motorized devices 7ai. Then we leave the initialization mode. The installation thus initialized is then operational.

Un premier mode de fonctionnement est définit comme suit : en cas de vent dépassant les seuils fixés, un ordre de commande de repli de l'élément mobile est exécuté, et en cas de vitesse de vent inférieure aux seuils fixés, un ordre de commande de déploiement de l'élément mobile est exécuté ou un ordre de commande de déploiement de l'élément mobile est autorisé. Les valeurs seuil d'effets du vent WEi peuvent être choisies identiques pour les dispositifs motorisés de même type.A first operating mode is defined as follows: in the event of a wind exceeding the set thresholds, a folding control command of the movable element is executed, and in the event of a wind speed lower than the set thresholds, a control command of deployment of the mobile element is executed or a deployment control command of the mobile element is allowed. The wind effect threshold values Wei can be chosen identical for the motorized devices of the same type.

Les seuils de protection sont en principe choisis de manière à éviter l'endommagement de la structure ou de l'écran, le confort visuel ou sonore peut cependant conduire l'utilisateur à préférer une valeur de seuil plus basse, par exemple pour éviter des vibrations trop importantes de l'écran.The protection thresholds are in principle chosen so as to avoid damaging the structure or the screen, the visual or audible comfort may, however, lead the user to prefer a lower threshold value, for example to avoid vibrations. too important of the screen.

L'utilisation conjointe de deux dispositifs de mesure permet un apprentissage au niveau de l'élément mobile entre la mesure de vitesse de vent et les effets du vent sur l'élément mobile, éventuellement en tenant compte de la position du dispositif de mesure de vitesse de vent. Cet apprentissage peut ensuite être utilisé pour gérer les temporisations suivant les replis de l'élément mobile, les positions de repli, tout en maintenant l'élément mobile dans une position de sécurité. Il est ainsi possible d'améliorer les enseignements de dispositifs tels que décrits dans le brevet EP 0 916 161 par exemple.The joint use of two measuring devices allows a learning at the level of the movable element between the measurement of wind speed and the effects of the wind on the moving element, possibly taking into account the position of the speed measuring device. Wind. This learning can then be used to manage the delays following the folds of the movable element, the fallback positions, while keeping the movable element in a safety position. It is thus possible to improve the teachings of devices as described in the patent EP 0 916 161 for example.

L'installation peut être placée dans un mode d'apprentissage dans lequel elle enregistre pour ses différents dispositifs motorisés 7ai munis de capteurs d'effets du vent des valeurs mesurées d'effets du vent et des valeurs mesurées de vitesse du vent à des instants donnés et établit une corrélation entre ces valeurs.The installation can be placed in a learning mode in which it records for its various motorized devices 7ai equipped with wind effect sensors measured values of wind effects and measured values of wind speed at given times. and correlates these values.

Plusieurs méthodes peuvent être utilisées pour réaliser cette corrélation. On peut par exemple de manière simple enregistrer le seuil de vitesse de vent WS2i égal à la valeur de vitesse de vent WS au moment où la valeur mesurée WE par le capteur des effets du vent dépasse la valeur seuil WEi. On peut également de manière plus complexe enregistrer différentes valeurs de vitesse de vent et différentes valeurs d'effets du vent et établir une loi liant ces valeurs. Un exemple de procédure est illustré à la figure 2. Pour chaque dispositif motorisé 7ai, on enregistre au cours d'une étape d'initialisation 10, les valeurs seuil WS1i et WEi. Lorsque, lors d'une étape 11, la valeur mesurée WE par le capteur des effets du vent dépasse la valeur seuil WEi, on prend en compte la valeur de vitesse de vent WS pour définir, lors d'une étape 12, une valeur seuil de vitesse de vent WS2i en fonction de WS et éventuellement d'une valeur précédente WS2i. Une nouvelle valeur de seuil de vitesse de vent WS3i, inférieure à WS2i, peut alors être calculée, lors d'une étape 13, en fonction de WS2i.Several methods can be used to achieve this correlation. For example, it is easy to record the wind speed threshold WS2i equal to the wind speed value WS at the moment when the measured value WE by the wind effect sensor exceeds the threshold value WEi. It is also more complex to record different values of wind speed and different values of wind effects and establish a law linking these values. An example of a procedure is shown in figure 2 . For each motorized device 7ai, the threshold values WS1i and WEi are recorded during an initialization step 10. When, during a step 11, the measured value WE by the wind effect sensor exceeds the threshold value WEi, the wind speed value WS is taken into account to define, during a step 12, a threshold value wind speed WS2i according to WS and possibly a previous value WS2i. A new wind speed threshold value WS3i, lower than WS2i, can then be calculated, in a step 13, as a function of WS2i.

Cette corrélation peut également tenir compte de la position de l'élément mobile. En effet, les effets du vent subis par l'élément mobile sont fonction du vent et de la position de l'élément mobile. Une fois cette corrélation établie, l'installation sort du mode d'apprentissage.This correlation can also take into account the position of the movable element. Indeed, the effects of the wind undergone by the movable element are a function of the wind and the position of the movable element. Once this correlation is established, the installation exits the learning mode.

L'installation peut fonctionner suivant un mode schématisé en figure 3, dans lequel la valeur seuil de vitesse du vent WS2i ou WS3i permet, lorsque l'écran a été déployé lors d'une étape 14 et lorsque le dispositif de mesure de la vitesse du vent mesure une valeur WS supérieure à cette valeur seuil dans une étape de test 15, de valider une action de repli de l'élément mobile 2i lors d'une étape 16. Un ordre de repli peut être maintenu tant que la vitesse du vent WS n'est pas redescendue au-dessous d'un seuil de sécurité, par exemple WS1i comme schématisé à l'étape 17. Il peut être couplé avec une temporisation. L'ordre de repli est inhibé par une information provenant du dispositif 4, dès que la vitesse du vent est détectée en dessous du seuil de sécurité WS1 i. Les capteurs 3i servent alors, dans ce mode de fonctionnement, de double sécurité. Dans une variante, l'ordre de repli peut être assuré par les capteurs 3i et le dispositif 4, c'est-à-dire par le capteur pour lequel le dépassement de seuil intervient le plus tôt.The installation can operate in a schematic way in figure 3 , in which the wind speed threshold value WS2i or WS3i allows, when the screen has been deployed during a step 14 and when the wind speed measuring device measures a WS value higher than this threshold value in a test step 15, to validate a folding action of the movable element 2i during a step 16. A fallback order can be maintained as the wind speed WS has not fallen below a threshold security, for example WS1i as shown schematically in step 17. It can be coupled with a timer. The fallback order is inhibited by information from the device 4, as soon as the wind speed is detected below the safety threshold WS1 i. The sensors 3i then serve, in this mode of operation, double security. In a variant, the order of fallback can be provided by the sensors 3i and the device 4, that is to say by the sensor for which the threshold overrun occurs as soon as possible.

On peut prévoir également, dans ce deuxième mode de fonctionnement, que les valeurs fournies par les capteurs 3i et le dispositif 4 continuent à être enregistrées selon le mode d'apprentissage, de manière à affiner la corrélation par des mesures et/ou calculs supplémentaires.It can also be provided in this second mode of operation, that the values provided by the sensors 3i and the device 4 continue to be recorded according to the learning mode, so as to refine the correlation by additional measurements and / or calculations.

Une troisième valeur seuil de vitesse du vent WS3i, inférieure à la valeur seuil WS2i peut être enregistrée pour être utilisée comme valeur seuil déclenchant une action de repli de l'élément mobile à la place de la valeur seuil WS2i.A third wind speed threshold value WS3i, lower than the threshold value WS2i, can be recorded for use as a threshold value triggering a fallback action of the moving element in place of the threshold value WS2i.

Les valeurs seuil de vitesse du vent WS1i, WS2i, WS3i peuvent être identiques pour les dispositifs motorisés installés sur une même façade.The wind speed threshold values WS1i, WS2i, WS3i may be identical for motorized devices installed on the same facade.

Le comportement des éléments mobiles peut suivre une loi de "tout ou rien" entre leurs positions repliée et déployée, mais de préférence, les éléments mobiles sont capables d'adopter une pluralité de positions en fonction des valeurs fournies à la fois par le dispositif de mesure de vitesse de vent et le dispositif de mesure des effets du vent.The behavior of the moving elements may follow an "all or nothing" law between their folded and deployed positions, but preferably the moving elements are capable of adopting a plurality of positions depending on the values provided by both the wind speed measurement and the wind effect measuring device.

Le procédé selon l'invention trouve son application particulièrement dans les bâtiments du tertiaire, qui comprennent généralement une pluralité d'éléments mobiles, disposés sur des façades différentes et donc soumis à des contraintes dues au vent très diverses.The method according to the invention finds its application particularly in tertiary buildings, which generally comprise a plurality of movable elements, arranged on different facades and therefore subject to very diverse wind loads.

L'installation peut bien évidemment comprendre des dispositifs motorisés (7b) dépourvu de capteur et réagissant différemment aux détections de franchissement de seuils.The installation may of course include motorized devices (7b) devoid of sensors and reacting differently to threshold crossing detections.

Les différents dispositifs de mesure et capteurs peuvent être autonomes, alimentés par pile ou par source d'énergie de type photovoltaïque.The different measuring devices and sensors can be autonomous, powered by battery or by photovoltaic energy source.

L'installation peut comprendre plusieurs dispositifs 4 de mesure de la vitesse du vent. Elle peut notamment comprendre un dispositif de mesure de vitesse du vent pour chacun des dispositifs motorisés 7ai.The installation may comprise several devices 4 for measuring the wind speed. It may include a device for measuring wind speed for each of the motorized devices 7ai.

Le terme « valider » une action de repli ou une action de déploiement doit être compris comme ayant deux significations. Il peut être synonyme de « commander l'exécution » ou d'« autoriser l'exécution » d'une action de repli ou d'une action de déploiement.The term "validate" a fallback action or deployment action should be understood as having two meanings. It can be synonymous with "Order execution" or "authorize execution" of a fallback action or deployment action.
