Abstract

The installation includes a solar protection blind (1) which can be displaced between a retracted position and a deployed position and is supported on a roller (2). A motor (3) is provided to operate the blind and is associated with a control system (4,10). The control system has a detector (10) which senses the solar radiation and provides a signal when a threshold is exceeded. The sensor is linked to a logic processing unit (4) which includes a timer that enables the system to respond when the sun's intensity changes, but without responding to every temporary change. Further sensors (11,12) provide astronomical information and detect twilight conditions in order to provide more appropriate control of operation of the blind.

Description

L'invention concerne une installation de protection solaire comprenant un élément de protection solaire déplaçable entre une position relevée et une position déployée, un moteur d'entraínement de cet élément de protection solaire et des moyens de commande de ce moteur comprenant un détecteur de seuil d'ensoleillement délivrant un signal, une unité logique de traitement dudit signal et de commande du moteur comprenant un moyen de temporisation de l'envoi d'un ordre au moteur lors de la disparition du soleil, temporisation dite "de disparition".The invention relates to a protective installation solar including a sun protection element movable between a raised position and a position deployed, a drive motor for this element of sun protection and control means of this motor comprising a threshold detector of sunshine delivering a signal, a logical unit processing said signal and controlling the motor comprising means for delaying the sending of a order to the engine when the sun disappears, so-called "disappearance" delay.

Une telle installation est notamment commercialisée par la demanderesse. Elle comporte également une temporisation d'apparition. Les temporisations d'apparition et de disparition ont pour but d'éviter des mouvements intempestifs inutiles et dérangeant de l'élément de protection solaire lors de brefs passages de nuages devant le soleil. L'ambiance est considérée comme ensoleillée si le soleil est présent pendant un temps défini et comme assombrie si le soleil disparait pendant un temps défini. Ces temporisations sont fixées en usine.Such an installation is sold in particular by the plaintiff. It also includes a appearance delay. The timers of appearance and disappearance are intended to avoid unnecessary and disturbing untimely movements the sun protection element during brief passages of clouds in front of the sun. The atmosphere is considered as sunny if the sun is present for a defined time and as darkened if the sun disappears for a defined time. These timers are fixed in the factory.

Il s'avère toutefois que de telles installations automatiques n'apportent pas le confort souhaité par l'utilisateur. En effet, en cas de ciel chargé de nuages, l'utilisateur est gêné par les mouvements inutilement fréquents de l'élément de protection solaire et il est mécontent de l'absence de réaction immédiate lors d'une première apparition du soleil au petit matin ou de sa disparition au crépuscule. Dans le premier cas, les temporisations sont donc considérées comme trop courtes et dans les autres cas comme trop longues. L'utilisateur dispose certes de la possibilité de régler le seuil d'ensoleillement, mais il se rend vite compte que quel que soit le réglage du seuil de déclenchement de l'automatisme, il a les mêmes gênes et, lassé, il préfèrera renoncer à l'automatisme en le débrayant. La durée des temporisations étant un compromis, la correction de l'une des gênes ne fera qu'augmenter l'autre et la possibilité offerte à l'utilisateur de régler le seuil d'ensoleillement ne résoud pas le problème.However, it turns out that such installations do not provide the comfort desired by the user. Indeed, in case of sky loaded with clouds, user is bothered by movement unnecessarily frequent protection element solar and he is unhappy with the lack of reaction immediately upon the first appearance of the sun at early morning or its disappearance at dusk. In the first case, the timers are therefore considered as too short and in other cases as too long. The user certainly has the possibility to adjust the sunshine threshold, but he surrenders quickly realize that whatever the threshold setting triggering the automation, it has the same genes and, weary, he would prefer to give up automation by disengaging. The duration of the timers being a compromise, the correction of one of the genes will not that increase the other and the opportunity offered to the user to adjust the sunshine threshold does not not solve the problem.

La démarche première consistait donc à identifier et poser clairement le problème et la seconde à lui apporter une solution.The first step was therefore to identify and clearly state the problem and the second to him provide a solution.

Le problème à résoudre consiste à obtenir une réaction rapide de l'automatisme, et partant de l'élément de protection solaire, lors de la première apparition du soleil, une temporisation suffisamment longue en cours de journée pour éviter des mouvements intempestifs en cas de ciel chargé de nuages et une réaction rapide lors de la disparition du soleil pour une durée prolongée, en particulier en fin de journée.The problem to solve is to get a reaction automation, and starting from the element of sun protection, when the sun, a sufficiently long time delay in progress to avoid unwanted movements during cloudy sky case and fast reaction when the sun disappears for a period prolonged, especially at the end of the day.

Afin de satisfaire ces exigences contradictoires, l'installation de protection solaire selon l'invention est caractérisée en ce que la temporisation de disparition part de l'instant où le seuil d'ensoleillement est franchi, vers le bas, c'est-à-dire descend en dessous du seuil et en ce que la durée de la temporisation de disparition varie en fonction inverse du temps d'ensoleillement écoulé depuis le dernier dépassement du seuil d'ensoleillement. In order to satisfy these conflicting requirements, the sun protection installation according to the invention is characterized in that the time delay of disappearance starts from the moment when the threshold of sunshine is crossed, down, that is to say goes below the threshold and in that the duration of the disappearance delay varies inversely the amount of sunshine since the last exceeding the sunshine threshold.

La temporisation d'apparition peut être soit supprimée, soit conservée. Dans le second cas, elle sera, de préférence, inférieure à 3 minutes.The appearance delay can be either deleted, be kept. In the second case, it will be, from preferably less than 3 minutes.

Ainsi, l'automatisme réagira pratiquement immédiatement à la première apparition du soleil, par exemple le matin d'une journée ensoleillée ou après la disparition des brouillards matinaux et plus longue a été la présence continue du soleil, moins l'automatisme attendra avant de réagir pour actionner l'élément de protection solaire lors de la disparition du soleil. Le passage consécutif de nuages, correspondant à des périodes d'ensoleillement relativement courtes, serait dès lors sans effet sur l'élément de protection solaire, qui resterait alors généralement en position déployée, alors qu'une longue période d'ensoleillement due à un ciel sans nuage et précédant la disparition du soleil pour la nuit entraínera un relevage quasi immédiat de l'élément de protection solaire.The automation will therefore react almost immediately at the first appearance of the sun, for example the morning of a sunny day or after disappearance morning mists and longer was the continuous presence of the sun, minus the automation will wait before reacting to activate the element of sun protection when the sun disappears. The consecutive passage of clouds, corresponding to relatively short periods of sunshine, would be therefore has no effect on the protective element solar, which would then generally stay in position deployed, while a long period of sunshine due to a cloudless sky and preceding the disappearance of the sun for the night will cause almost a lift the sun protection element.

L'action peut être un relevage ou un abaissement, selon l'installation concernée.The action can be a raising or lowering, depending on the installation concerned.

Il est possible d'augmenter encore le confort de l'installation en munissant celle-ci de moyens assurant dans tous les cas l'actionnement immédiat de l'élément de protection solaire au coucher du soleil.It is possible to further increase the comfort of the installation by providing it with means ensuring in all cases the immediate actuation of the element sunscreen at sunset.

Selon un mode d'exécution, l'installation est associée à une horloge astronomique et l'unité logique de traitement comprend des moyens de calcul de l'heure du coucher du soleil et d'intégration de cette heure dans le calcul de la temporisation de disparition de manière à introduire une correction de cette temporisation en fonction de l'heure, en particulier pour réduire, voire annuler, la temporisation de disparition lorsque l'heure de l'horloge astronomique est proche de l'heure du coucher du soleil.According to an embodiment, the installation is associated to an astronomical clock and the logical unit of processing includes means for calculating the time of the sunset and integrating this hour into calculating the disappearance delay so to introduce a correction of this time delay in time function, in particular to reduce or even cancel, the disappearance delay when the time on the astronomical clock is close to the time of the sunset.

Selon un autre mode d'exécution, l'installation comprend un capteur solaire fournissant une information sur la hauteur du soleil au dessus de l'horizon et l'unité logique de traitement comprend des moyens d'intégration de l'information délivrée par le capteur pour apporter une correction à la valeur de la temporisation calculée, en particulier pour réduire, voir annuler, la temporisation lorsque le soleil est sur le point de disparaítre ou disparaít.According to another embodiment, the installation includes a solar collector providing information on the height of the sun above the horizon and the logical processing unit comprises means integration of the information delivered by the sensor to make a correction to the value of the calculated delay, in particular to reduce, see cancel, the time delay when the sun is about to disappear or disappear.

Selon un autre mode d'exécution, l'installation comprend un capteur crépusculaire délivrant à l'ULT un signal lorsque la lumière atteint une valeur choisie comme représentant le crépuscule et l'ULT est programmée de manière à commander l'actionnement immédiat de l'élément de protection solaire à réception du signal du capteur crépusculaire.According to another embodiment, the installation includes a twilight sensor delivering to the ULT a signal when the light reaches a chosen value as representing twilight and the ULT is programmed to control actuation immediately of the sun protection element upon receipt of the twilight sensor signal.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution, ainsi que des variantes, de l'installation selon l'invention.The accompanying drawing shows, by way of example, a mode of execution, as well as variants, of the installation according to the invention.

La figure 1 est une vue schématique du mode d'exécution principal de l'installation, vue dans laquelle deux variantes sont également représentées et reconnaissables par des flèches en traits discontinus.Figure 1 is a schematic view of the embodiment main of the installation, view in which two variants are also shown and recognizable by arrows in broken lines.

La figure 2 représente l'organigramme du programme enregistré dans l'unité logique de traitement.Figure 2 shows the program flowchart stored in the logical processing unit.

La figure 3 est un premier exemple de fonction de la variation de la temporisation de disparition.Figure 3 is a first example of a function of the variation of the disappearance delay.

La figure 4 est un second exemple de cette même fonction.Figure 4 is a second example of this same function.

La figure 1 montre schématiquement une toile de store solaire 1 s'enroulant sur un tambour d'enroulement 2 entraíné par un moteur électrique 3. Le moteur 3 est commandé par une unité logique de traitement (ULT) 4 comprenant un calculateur 5, une horloge 6, une mémoire ROM 7 et une mémoire RAM 8 et une interface entrées/sorties 9. L'installation comprend en outre une sonde photosensible 10. Une telle sonde est largement utilisée dans les installations actuelles. Elle sert à déterminer un seuil d'ensoleillement, c'est-à-dire la présence d'un éclairage direct de la sonde par le soleil.Figure 1 shows schematically a blind fabric solar 1 winding on a winding drum 2 driven by an electric motor 3. The motor 3 is controlled by a logical processing unit (ULT) 4 comprising a computer 5, a clock 6, a memory ROM 7 and RAM 8 and interface inputs / outputs 9. The installation also includes a photosensitive probe 10. Such a probe is widely used in current installations. It is used to determine a sunshine threshold, i.e. the presence of direct lighting of the probe by the Sun.

Dans la mémoire RAM 8 de l'ULT 4, est enregistré un programme dont l'organigramme est représenté à la figure 2.In the RAM memory 8 of the ULT 4, a program whose organizational chart is shown in figure 2.

Dans le programme tel que représenté, la temporisation d'apparition est égale à zéro.In the program as shown, the timer of appearance is zero.

Le programme ayant été initialisé, l'ULT teste la présence du soleil, c'est-à-dire si le seuil d'ensoleillement a été atteint. Dans l'affirmative, l'ULT commande immédiatement le déployement de la protection solaire et inialise simultanément un comptage du temps d'ensoleillement. La présence du soleil continue à être testée. Dès que le soleil disparaít, l'ULT calcule une temporisation de disparition selon une fonction enregistrée, par exemple l'une des fonctions représentée à la figure 3 ou 4. The program having been initialized, the ULT tests the presence of the sun, i.e. if the threshold has been reached. In the affirmative, the ULT immediately orders the deployment of the sun protection and simultaneously initializes a counting of sunshine time. The presence of sun continues to be tested. As soon as the sun disappears, the ULT calculates a time delay of disappearance according to a registered function, for example one of the functions shown in Figure 3 or 4.

Quelle que soit la fonction enregistrée, dans tous les cas la durée de la temporisation de disparition varie en fonction inverse du temps d'ensoleillement écoulé depuis le dernier dépassement du seuil d'ensoleillement, c'est-à-dire du temps mesuré par le compteur. La temporisation calculée est immédiatement initialisée. Durant cette temporisation, l'ULT continue à tester la présence de l'ensoleillement. Aussi longtemps que le soleil est absent, la temporisation de disparition se poursuit. Par contre, si le soleil revient durant cette temporisation, le compteur du temps d'ensoleillement, qui venait d'être mis à zéro, recommence et le programme reprend à partir de cette nouvelle initialisation du comptage du temps d'ensoleillement.Whatever the registered function, in all case the duration of the disappearance delay varies inversely as a function of the sunshine time elapsed since the last crossing of the threshold of sunshine, i.e. the time measured by the counter. The calculated delay is immediately initialized. During this time delay, the ULT continues to test the presence of sunshine. As well as long as the sun is absent, the time delay of disappearance continues. However, if the sun returns during this time delay, the counter of sunshine time, which had just been zeroed, starts again and the program resumes from this new time count initialization of sunshine.

Si la temporisation de disparition arrive à son terme sans que le soleil soit revenu, la protection solaire est relevée et le programme recommence au début.If the disappearance timer expires without the sun coming back, sun protection is raised and the program starts again at the beginning.

Il est possible d'introduire une temporisation d'apparition dans ce programme entre la première détection de la présence du soleil (seuil d'ensoleillement) et le déploiement de la protection solaire. Par contre, cette temporisation n'a aucun effet sur le début du comptage du temps d'ensoleillement. La durée de la temporisation d'apparition est fixée en usine. Elle est inférieure à trois minutes. Comme on l'a vu, elle peut être nulle.It is possible to enter a time delay of appearance in this program between the first detection of the presence of the sun (threshold ) and the deployment of protection solar. On the other hand, this timeout has no effect on the start of time counting of sunshine. The duration of the delay appearance is fixed at the factory. It is less than three minutes. As we have seen, it can be zero.

Le seuil d'ensoleillement peut être soit ajustable par l'utilisateur soit fixé en usine. Dans le second cas, sa valeur est généralement fixée à 10 klux.The sunshine threshold can be either adjustable by the user is fixed at the factory. In the second case, its value is generally set at 10 klux.

Les fonctions donnant la valeur de la temporisation de disparition en fonction du temps d'ensoleillement mesuré depuis le dernier dépassement du seuil d'ensoleillement représentées aux figures 3 et 4 ne sont que des exemples. De telles fonctions sont aisément intégrables dans l'ULT.The functions giving the value of the time delay disappearance as a function of sunshine time measured since the last crossing of the threshold of sunshine shown in Figures 3 and 4 do are just examples. Such functions are easily integrated into the ULT.

Pour l'utilisateur, ces fonctions signifient que plus longue a été la présence du soleil, moins l'automatisme attendra avant de réagir. Lors de passages consécutifs de nuages, la temporisation de disparition sera relativement longue, de telle sorte qu'on évitera des mouvements intempestifs de la protection solaire. Par contre, en fin de journée, après une longue période d'ensoleillement, la temporisation de disparition sera très courte, de telle sorte que la protection solaire sera relevée rapidement après la disparition du soleil.For the user, these functions mean that more long was the presence of the sun, minus the automation will wait before reacting. During consecutive passages of clouds, the disappearance delay will be relatively long, so that nuisance movements of the sun protection. By against, at the end of the day, after a long period sunshine, the disappearance delay will be very short, so that the sun protection will be raised quickly after the sun disappears.

L'installation peut être encore perfectionnée en fournissant à l'ULT une information complémentaire.The installation can be further improved by providing the ULT with additional information.

Selon un premier perfectionnement, l'ULT 4 a accès à une horloge astronomique 11 qui lui permet de connaítre les heures de lever et de coucher du soleil. L'ULT peut ainsi intégrer, au moment du calcul de la durée de la temporisation de disparition, l'heure réelle de la journée. Lors du calcul de la temporisation de disparition selon une des fonctions représentées, si l'heure de la journée est proche de l'heure du coucher du soleil connue de l'horloge astronomique, la temporisation de disparition est, par exemple, réduite à une valeur inférieure à trois minutes. Par contre, en milieu de journée, lorsque le ciel est très lumineux, l'utilisateur sera beaucoup moins sensible à une variation de la luminosité ambiante et ne souhaitera pas que sa protection solaire se retire et lui donne l'impression de toujours bouger. Par conséquent, dans ce cas, la durée de la temporisation de disparition sera augmentée.According to a first improvement, the ULT 4 has access to an astronomical clock 11 which allows him to know sunrise and sunset times. The ULT can thus integrate, when calculating the duration of the disappearance delay, the actual time of the day. When calculating the time delay of disappearance according to one of the functions represented, if time of day is close to bedtime of the sun known from the astronomical clock, the disappearance delay is, for example, reduced at a value less than three minutes. However, in mid-day, when the sky is very bright, the user will be much less sensitive to a variation in ambient light and will only wish not that his sunscreen takes off and gives him the impression of always moving. Therefore, in this case the duration of the disappearance delay will be increased.

L'information fournie par l'horloge astronomique permettra en outre à l'automatisme de faire la différence, en fin de journée, entre le passage d'un nuage et le crépuscule. En outre, au crépuscule, l'automatisme pourra tenir compte de l'information reçue de l'horloge astronomique pour précipiter la remontée de la protection solaire quelle que soit la saison.Information provided by the astronomical clock will also allow the automation to do the difference, at the end of the day, between the passage of a cloud and twilight. Also, at dusk, the automation can take the information into account received from the astronomical clock to rush the rising sun protection whatever the season.

Selon un autre perfectionnement, l'ULT 4 est associée à un capteur crépusculaire 12, tel qu'utilisé, par exemple, pour enclencher un éclairage public. L'automatisme sera ainsi capable de distinguer un nuage du crépuscule et de commander immédiatement le relevage de la protection solaire au crépuscule déterminé par le capteur crépusculaire.According to another improvement, the ULT 4 is associated with a twilight sensor 12, as used, by example, to activate public lighting. The automation will be able to distinguish a cloud at dusk and immediately order the lifting of sun protection at dusk determined by the twilight sensor.

Le capteur crépusculaire peut être la sonde photosensible 10 elle-même.The twilight sensor can be the probe photosensitive 10 itself.

Le capteur crépusculaire 12 peut être remplacé par un capteur solaire capable de suivre l'élévation du soleil. De tels capteurs sont bien connus et donnent une information sur l'heure solaire dont l'ULT peut tenir compte pour modifier la durée de la temporisation de disparition.The twilight sensor 12 can be replaced by a solar collector capable of tracking the elevation of the Sun. Such sensors are well known and give information on solar time which the ULT can take into account to modify the duration of the delay of disappearance.
