Definitions
- 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.
- Such an installation is described in the document FR-A-2 544 887. It also includes a appearance delay.
- the timers of appearance and disappearance are intended to avoid unnecessary and disturbing untimely movements of 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.
- the first step therefore consisted in identifying and clearly state the problem and the second to him provide a solution.
- 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.
- 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.
- the appearance delay can be either deleted, be kept. In the second case, it will be, from preferably less than 3 minutes.
- 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 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 almost lift the sun protection element.
- the action can be a raising or lowering, depending on the installation concerned.
- 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.
- 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.
- the installation includes a twilight sensor delivering to the ULT a signal when the light reaches a selected 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.
- 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.
- Figure 2 shows the program flowchart stored in the logical processing unit.
- Figure 3 is a first example of a function of the variation of the disappearance delay.
- Figure 4 is a second example of this same function.
- FIG. 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.
- ULT logical processing unit
- 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 illumination of the probe by the Sun.
- 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.
- 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.
- the ULT continues to test the presence of sunshine. Also 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 set to zero, starts again and the program resumes from this new time count initialization sunshine.
- this timeout has no effect on the start of time counting 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.
- the sunshine threshold can be either adjustable by the user is fixed at the factory. In the second case, its value is generally fixed at 10 klux.
- these functions mean that more long was the presence of the sun, minus the automation will wait before reacting.
- the disappearance delay will be relatively long, so that nuisance movements of the sun protection.
- the disappearance delay will be very short, so that the sun protection will be raised quickly after the sun disappears.
- the installation can be further improved by providing the ULT with additional information.
- 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.
- the disappearance delay is, for example, reduced at a value less than three minutes.
- the duration of the disappearance delay will be increased.
- 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.
- 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.
- the twilight sensor can be the probe photosensitive 10 itself.
- 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.
