Description

Method of operating a concealment or solar protection installation and associated installation

The present invention relates to a method of operating a screening or solar protection installation.

The present invention also relates to an installation adapted to implement this operating method.

Generally speaking, the present invention relates to the field of concealment devices comprising a motorized drive device setting in motion a screen, between at least a first position and at least a second position.

A motorized drive device comprises an electromechanical actuator of a mobile occultation or solar protection element, such as a rolling shutter, a blind, a curtain, a swing shutter or any other equivalent material, hereinafter called screen .

We already know the document EP 3 904 630 A1 which describes a concealment or solar protection installation comprising a concealment device, a window of a building and an illuminance sensor. The concealment device comprises a screen, a motorized drive device and an electrical energy supply device. The screen is configured to move opposite the building window. The motorized drive device includes an electromechanical actuator and an electronic control unit. The electromechanical actuator is configured to move the screen. The electromechanical actuator is electrically connected to the electrical energy supply device. The electrical energy supply device comprises a photovoltaic panel and a battery. The photovoltaic panel is electrically connected to the battery.

This installation is configured to implement a method of controlling the installation in operation comprising a first step of determining a solar mask facing the photovoltaic panel and a second step of determining a position of the sun in this solar mask . This process is generally satisfactory.

However, this installation has the disadvantage that the concealment device is placed inside the building and the photovoltaic panel is fixed to the screen of the concealment device.

Consequently, the photovoltaic panel may not be exposed to direct solar radiation at least certain times of a day, because of another occultation device placed outside the building or because the photovoltaic panel may be raised above the window and it is hidden by a wall of the building.

In addition, this document EP 3 904 630 A1 is silent as to the use of the photovoltaic panel as an illuminance sensor.

Furthermore, this document EP 3 904 630 A1 is silent as to the positioning of the illuminance sensor in relation to the installation.

In the case where the illuminance sensor is fixed outside the building, in particular on a box of another occultation device placed outside the building or offset on a wall of the building, this sensor illuminance may not be exposed to direct solar radiation at least certain times of a day, due to an element of the architecture of the building and, more particularly, a window lintel, an overhang roof or balcony.

Thus, the illuminance sensor may not be relevant, at least occasionally, to authorize or prohibit movement of the screen of the concealment device by means of the electromechanical actuator, depending on the data collected by the latter and transmitted to a controller of a terminal, configured to issue control orders to the electronic control unit of the motorized drive device.

In this way, a movement of the screen of the occultation device may not be carried out by means of the electromechanical actuator, depending on the data coming from the illuminance sensor, while the window is exposed to direct solar radiation . In such a case, the illuminance sensor may be masked by an element of the building's architecture, such as, for example, a window lintel, a roof overhang or a balcony. And conversely, a movement of the screen of the occultation device can be carried out by means of the electromechanical actuator, depending on the data coming from the illuminance sensor when the latter is exposed to direct solar radiation, while the window is not exposed to direct solar radiation. Such a case can, in particular, occur when the illuminance sensor is used to control a plurality of occultation devices arranged respectively opposite a different window of the same facade of the building.

Consequently, the absence of movement of the screen of the occultation device or this or these movements of the screen of the occultation device can harm the thermal management of the building and/or the glare inside. of the building and therefore cause user dissatisfaction.

The present invention aims to resolve the aforementioned drawbacks and to propose a method of operating a concealment or solar protection installation, as well as a concealment or solar protection installation, making it possible to avoid inappropriate operation. of an electromechanical actuator for moving a screen of a concealment device opposite a window of a building, as a function of data coming from an illuminance sensor, which is generated by a location of the illuminance sensor not representative of direct solar radiation on the window.

Furthermore, depending on the result of the first comparison step, if the position of the sun determined, during the third determination step, is within the operating zone of the illuminance sensor, then the method implements carries out a first step of selecting the illuminance sensor, so as to authorize movement of the screen by means of the electromechanical actuator, as a function of data coming from the selected illuminance sensor, during the first selection step.

Thus, the method makes it possible to avoid inappropriate operation of the electromechanical actuator to move the screen of the occultation device opposite the window of the building, as a function of data coming from the illuminance sensor, which is generated by a location of the illuminance sensor not representative of direct solar radiation on the window.

More generally, the method according to the invention can be implemented on an architecture of distributed hardware and software means.

Advantageously, the method comprises a step E100 of obtaining a geographical location of the installation 100, in particular a latitude of the installation 100 and, possibly, a longitude of the installation 100.

Advantageously, the obtaining step E100 is implemented by means of the satellite positioning device 39 of the terminal 12, 13, 33.

This geographical location of installation 100 may correspond to that of terminal 12, 13, 33.

The terminal 12, 13, 33 can display, for example, the longitude, the latitude and, optionally, the altitude of the installation 100, by means of the display element(s) 34.

The method comprises a first step of determining E110 of a first solar mask M1 facing the illuminance sensor 43.

The first solar mask M1 corresponds to one or more obstacles arranged opposite the illuminance sensor 43 and capable of causing a shadow on it relative to the sun, in the assembled configuration of the installation 100, at a given time, particularly over the course of a year. This or these obstacles can be, for example, an element of the architecture of the building and, more particularly, of a lintel of the window 40, of a roof overhang or of a balcony of the building, another building, which may be, in particular, a house or a building, vegetation, which may be, in particular, a shrub or a tree, a relief of the landscape around the installation 100, which may be, in particular, a mountain. This or these obstacles defining data from the first solar mask M1 can reduce, or even stop, the production of electrical energy by the photovoltaic panel 25 as a function of energy inputs from the sun.

The first solar mask M1, also called the first shading mask, is thus a representation of elements projecting, according to the direction defined on the abscissa and on the ordinate, a shadow at a location of the illuminance sensor 43 in the installation 100.

Advantageously, the first solar mask M1 is determined by taking one or more photographs. Taking the photograph(s) can be implemented using the mobile terminal 33 and, more particularly, the camera 37 of the mobile terminal 33.

Advantageously, the first determination step E110 comprises at least:

Here, the first determination sub-step E113 makes it possible to determine an orientation of the camera 37 of the mobile terminal 33 relative to a reference R and, possibly, an inclination of the camera 37 of the mobile terminal 33 relative to the ground and/or a plate of the camera 37 of the mobile terminal 33, that is to say a rotation with respect to each of the axes X, Y, Z of a three-dimensional reference frame.

Advantageously, the first determination step E110 further comprises, following the taking sub-step E112, a second determination sub-step E114 of at least one sky area C from the photograph P, taken during the socket sub-step E112, by means of the controller 35 of the mobile terminal 33.

Advantageously, the second determination sub-step E114 comprises a first image processing.

Advantageously, the first image processing, during the second determination sub-step E114, is implemented by the controller 35 of the terminal 12, 13, 33, in particular by means of software embedded by the controller 35 of the terminal 12, 13, 33.

An example of the result of the first image processing of the photograph P is illustrated in Figure . Here, the white part of the corresponds to sky zone C.

Advantageously, the first image processing, during the second determination sub-step E114, consists of carrying out a binary segmentation of the photograph P to separate the sky C from the other elements of the photograph P.

In an exemplary embodiment, such binary segmentation of the photograph P consists of evaluating a radiometry, in particular of the RGB type (acronym for the Anglo-Saxon term Red Green Blue), of the pixels of the photograph P, so as to determine a brightness of each pixel of the photograph P, and to determine for each column of pixels of the photograph P brightness gradients. When the luminosity gradient is high and, in particular, greater than a predetermined threshold, this can correspond to a border between the sky C and another element of the photograph P.

Advantageously, the photograph P, taken during the taking sub-step E112, can be converted into a black and white image. For example, the pixels of the image representing the sky C are transformed into white pixels, corresponding to a first binary state assigned, for example, to a value “0”; and all other pixels are converted into black pixels, corresponding to a second binary state assigned, for example, to a value “1”.

Advantageously, the first determination step E110 comprises a sub-step of entering or retrieving E115 of the date and time during the capture sub-step E112.

Here, the input or recovery sub-step E115 is implemented by means of the controller 35 of the terminal 12, 13, 33.

Alternatively or in addition, the entry or recovery sub-step E115 is implemented through the selection elements 14 and display elements 34 of the terminal 12, 13, 33 and/or data transmitted by the server 28 to the second communication module 36 of the terminal 12, 13, 33.

Advantageously, the first determination step E110 comprises a second recording sub-step E116 of the date and time entered or retrieved, during the input or recovery sub-step E115, in particular in a memory of the controller 35 from terminal 12, 13, 33.

Advantageously, the date and time are updated automatically by means of a clock, in particular of the real-time clock type, commonly called RTC (acronym for the Anglo-Saxon term “Real Time Clock”). Such a clock can be integrated into the controller 35 of the terminal 12, 13, 33.

Advantageously, the first determination step E110 further comprises, following the first determination sub-step E113, a projection sub-step E117 of data from the photograph P, taken during the taking sub-step E112, in a projection mark V.

Here, the projection sub-step E117 is implemented by means of the controller 35 of the terminal 12, 13, 33.

An example of the result of projecting the data from the photograph P into the projection reference frame V is illustrated in Figure .

Advantageously, the projection sub-step E117 is implemented as a function of orientation data of the camera 37 of the mobile terminal 33, determined during the first determination sub-step E113, which may be angles defining, in particular , a precession, in other words a pitch, a nutation, in other words roll, and a proper rotation, in other words a yaw. Such angles are commonly called Euler angles.

Here, the projection sub-step E117 corresponds to a step of changing the reference of the data of the photograph P, in particular from the reference R, for example cardinal, towards the projection reference V and, more particularly, from a reference three-dimensional centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33 towards the projection mark V.

Advantageously, the projection mark V is a mark in which azimuth and elevation angular coordinates are represented. To the , the azimuth is represented on the abscissa and the elevation is represented on the ordinate, in an orthogonal Cartesian coordinate system.

Advantageously, the projection reference V of the photograph P, taken during the taking sub-step E112, is a spherical celestial vault reference.

The so-called Euler angles make it possible to express in spherical coordinates, in particular in the projection reference frame V, the orientation of an element, in particular of the camera 37 of the mobile terminal 33, relative to a Cartesian frame, in other words a three-dimensional frame, in particular the R frame, which can also be called a cardinal frame.

Here, for each direction from the location of the photovoltaic panel 25 relative to the installation 100, in the projection reference frame V, an azimuth angle is assimilated to a proper rotation angle in the reference frame R and an angle elevation is assimilated to an angle of precession in the reference R.

Advantageously, the projection sub-step E117 of the data of the photograph P, taken during the taking sub-step E112, is implemented, in addition, as a function of a focal distance of an objective of the device photographic 37 of the mobile terminal 33.

Advantageously, the projection sub-step E117 of the data of the photograph P, taken during the taking sub-step E112, is implemented, in addition, as a function of the dimensions of an image sensor of the device photographic camera 37 of the mobile terminal 33, in other words the horizontal and vertical angles of field of the camera 37 of the mobile terminal 33.

In an exemplary embodiment, the projection sub-step E117, in the projection reference frame V, comprises a first sub-step of passing data from the photograph P of a first three-dimensional reference frame centered on a midpoint of the sensor image of the camera 37 of the mobile terminal 33 to a second three-dimensional reference point centered on a focal point of the lens of the camera 37 of the mobile terminal 33. This first sub-step of the projection sub-step E117 requires previously an input sub-step and a sub-step of memorization by the controller 35 of the terminal 12, 13, 33 of the focal length of the lens of the camera 37 of the mobile terminal 33 and the dimensions of the sensor image of the camera 37 of the mobile terminal 33. This first sub-step of the projection sub-step E117 thus makes it possible to obtain a result comprising three matrices, each expressing a coordinate of each pixel of the photograph P according to the X, Y, Z axes of the second three-dimensional coordinate system. In addition, the projection sub-step E117, in the projection reference frame V, comprises a second sub-step of passing the result of the first sub-step of the projection sub-step E117 from the second three-dimensional reference frame to the projection reference frame V centered on the focal point of the lens of the camera 37 of the mobile terminal 33. This second sub-step of the projection sub-step E117 first requires determining each angle, known as the Euler angle, during the first determination sub-step E113, and to apply by means of the controller 35 of the terminal 12, 13, 33 rotation matrices, called Euler, for each of these angles. This second sub-step of the projection sub-step E117 thus makes it possible to obtain a result comprising two matrices, each expressing a coordinate of each pixel of the photograph P according to the elevation and azimuth angles of the projection reference frame V .

Advantageously, the projection sub-step E117 is implemented as a function of the determined orientation of the camera 37 of the mobile terminal 33, during the first determination sub-step E113, of the focal length of the lens of the camera 37 of the mobile terminal 33, the dimensions of the image sensor of the camera 37 of the mobile terminal 33 and at least one angle, known as the Euler angle, determined during the first sub-step determination E113. The at least one of the so-called Euler angles to be taken into consideration is, in particular, at least one of the angles called proper rotation, precession and nutation and, preferably, all of the so-called Euler angles.

Advantageously, the first determination step E110 further comprises, following the first determination sub-step E113, in particular following the projection sub-step E117, a superposition sub-step E118 of data from the photograph P, taken during the taking sub-step E112, in particular of the photograph Pp, projected during the projection sub-step E117, on a solar path diagram, illustrated in the , in the reference R, in particular in the projection reference V, so as to determine the first solar mask M1 at the location of the illuminance sensor 43.

The solar path diagram, also called a solar diagram, is a diagram showing, at different times of the year, an angular height, also called angle height or elevation, of the sun and an azimuth of the direction of the sun for a given latitude. The solar path diagram thus makes it possible to define a trajectory of the sun perceived at the location of the illuminance sensor 43 in relation to the installation 100 for different times, during the year. In this way, the solar path diagram makes it possible to define moments during which direct incident solar radiation exists at the location of the illuminance sensor 43 relative to the installation 100, in particular in meteorological conditions where the sky C is clear and in the absence of obstacles to solar radiation.

The solar path diagram is an example of a graphical representation for a given latitude and longitude. Each curve represents an apparent path of the sun as a function of time for a specific date of the year.

Here, the solar path diagram is determined in the projection frame V.

Here, the superposition sub-step E118 is implemented by means of the controller 35 of the terminal 12, 13, 33.

The superposition of the data from the photograph P, taken during the taking sub-step E112, in particular from the photograph Pp, projected during the projection sub-step E117, on the solar path diagram, in the reference R, in particular in the projection reference V, thus makes it possible to determine at any moment, in particular during the year, whether the sun is visible or not at the location of the illuminance sensor 43 in relation to the installation 100 .

In order to implement the superposition sub-step E118, the data of the photograph P, in particular of the projected photograph Pp, and the data of the solar path diagram are expressed in the same reference frame, in other words in a common reference frame.

The common reference can be, in particular, a cardinal reference, a three-dimensional reference centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33, a three-dimensional reference centered on a focal point of the objective of the the photographic camera 37 of the mobile terminal 33 or a spherical celestial vault reference, also called projection reference.

Here, the superposition sub-step E118 is implemented from data from the photograph Pp, projected during the projection sub-step E117, on the solar path diagram. Here, the data of the projected photograph Pp are obtained from the data of the photograph P, taken during the taking sub-step E112.

Advantageously, the first determination step E110 comprises a third recording sub-step E119 of data defining the photograph P, taken during the taking sub-step E112, and, possibly, the photograph Pp, projected during the sub-step -projection step E117, in a memory of controller 35 of terminal 12, 13, 33.

Here, the projection and superposition sub-steps E117, E118 are obtained by geometric operations. The projection and superposition sub-steps E117, E118 are advantageously carried out without a display illustrating these sub-steps. These sub-steps can be grouped into a single calculation sub-step making it possible to determine the first solar mask M1.

The calculation sub-steps of the first determination step E110 have been described as being implemented in the terminal 12, 13, 33. However, these calculation sub-steps can alternatively be implemented partially or entirely in the server 28.

The method further comprises a second step E120 of determining the or each obstacle A belonging to an architectural element of the building, from the first solar mask M1 facing the illuminance sensor 43, so as to determine a operating zone F of the illuminance sensor 43 in the first solar mask M1.

Thus, the second determination step E120 makes it possible to discriminate the nature of the obstacles A, B and therefore to isolate the obstacle(s) A linked to an element of the architecture of the building, for example a lintel of the window 40, an overhang roof or balcony of the building, in relation to one or more other obstacles B linked to another building, which may be, in particular, a house or a building, to vegetation, which may be, in particular, a shrub or a tree, or to a relief of the landscape around the installation 100, which may be, in particular, a mountain.

In this way, the operating zone F of the illuminance sensor 43 makes it possible to define a so-called “relevance” solar mask of the illuminance sensor 43 or a building architecture solar mask.

The operating zone F of the illuminance sensor 43 can be formed of several sections F1, F2, F3, as illustrated in Figures 7 and 8, or of a single section, depending on the number of other obstacles B linked to a other building, vegetation or landscape relief around the installation 100 of the photograph P determined, during the second determination step E120.

The obstacle(s) A linked to an element of the architecture of the building are the obstacle(s) capable of preventing direct solar radiation on the illuminance sensor 43 but not necessarily on the window 40 of the building.

The photograph P, taken during the taking sub-step E112, includes an upper edge Ph, a lower edge Pb, a left edge Pg and a right edge Pd.

The photograph P, taken during the taking sub-step E112, is made up of a plurality of pixels, as described previously, arranged in the form of a matrix comprising rows and columns.

Here, the obstacle(s) A linked to an element of the architecture of the building are considered to be the obstacle(s) located along the upper edge Ph of the photograph P, taken during the taking sub-step E112.

Advantageously, the second determination step E120 comprises a second image processing.

Advantageously, the second image processing, during the second determination step E120, is implemented by the controller 35 of the terminal 12, 13, 33, in particular by means of software embedded by the controller 35 of the terminal 12, 13, 33.

An example of the result of the second image processing of the photograph P is illustrated in Figure . Here, the white part of the corresponds to the operating zone F of the illuminance sensor 43, in other words to a so-called “relevance” zone thereof.

Advantageously, the second image processing, during the second determination step E120, consists of carrying out a binary state change of the pixels of the matrix representative of the photograph P to separate the obstacle(s) A linked to an element of the the architecture of the building in relation to one or more obstacles B linked to another building, to vegetation or to a relief of the landscape around the installation 100 of the photograph P.

In the exemplary embodiment, the second determination step E120 comprises:

- a sub-step E121 of verifying the binary state of each pixel of the matrix representative of the photograph P by scanning each column of pixels, from the upper edge Ph of the photograph P to the lower edge Pb of the photograph P, then shifting column by column;

- if the binary state of a pixel corresponds to the color black, in other words to the first binary state assigned to the value "1", this pixel is considered to be part of an obstacle A linked to an element of the architecture of the building and a conservation sub-step E122 of this first binary state of this pixel is implemented; And

- if the binary state of a pixel corresponds to the white color, in other words to the second binary state assigned to the value "0", this pixel is considered to be part of the sky C and a conversion sub-step E123 of the The set of pixels located below, in other words towards the lower edge Pb of the photograph P, and in the same column as this pixel is implemented to switch these pixels into the second binary state.

Thus, all pixels initially white, in other words associated with the second binary state, are considered to be part of the sky C and all pixels converted from black to white, in other words converted from the first binary state to the second state binary, are considered to be part of another obstacle B linked to another building, to vegetation or to a relief of the landscape around the installation 100.

In this way, the operating zone F of the illuminance sensor 43 is defined by all the white pixels, in other words associated with the second binary state, of the matrix representative of the photograph P, obtained following the second processing of 'picture.

The method comprises a third step of determining E130 a position of the sun S, in the first solar mask M1 comprising the operating zone F of the illuminance sensor 43, in other words in the so-called "relevance" solar mask of the sensor d illumination 43.

Advantageously, the third determination step E130 is implemented from the date and time entered or retrieved, in particular as this is described previously during the entry or retrieval sub-step E115, and the geographical location of the installation 100 obtained, during the obtaining step E100, in particular through the solar path diagram. Date and time retrieval can be implemented, for example, via data provided by the clock.

Advantageously, the third determination step E130 comprises sub-steps of calculating data on the position of the sun S in an ecliptic coordinate frame, converting these data into an equatorial coordinate frame then into a horizontal coordinate frame, from the date and time entered or retrieved, in particular how this is described previously during the entry or recovery sub-step E115, and from the geographical location of the installation 100 obtained, during the step d obtaining E100.

The method further comprises a first step of comparison E140 of the position of the sun S determined, during the third determination step E130, with respect to the operating zone F of the illuminance sensor 43.

Depending on the result of the first comparison step E140, if the position of the sun S determined, during the third determination step E130, is within the operating zone F of the illuminance sensor 43, as illustrated in there , then the method implements a first selection step E150 of the illuminance sensor 43, so as to authorize movement of the screen 2 by means of the electromechanical actuator 11, as a function of data coming from the illuminance sensor 43 selected, during the first selection step E150.

Thus, the method makes it possible to avoid inappropriate operation of the electromechanical actuator 11 to move the screen 2 of the concealment device 3 opposite the window 40 of the building, as a function of data coming from the sensor d illuminance 43, which is generated by a location of the illuminance sensor 43 not representative of direct solar radiation on the window 40.

In this way, a movement of the screen 2 of the concealment device 3 is authorized to be carried out by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43, given that these are considered to be consistent with the expected direct solar radiation, in other words potential, over window 40.

In other words, a movement of the screen 2 of the concealment device 3 is authorized to be executed by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43, only when the position of the sun S is inside the operating zone F of the illuminance sensor 43.

In addition, the authorization of or each movement of the screen 2 of the concealment device 3 by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43, in the case where a measurement of sunshine by the illuminance sensor 43 is considered to be representative of direct solar radiation on the window 40, makes it possible to improve the thermal management of the building and/or glare inside the building and therefore to promote user satisfaction.

Advantageously, depending on the result of the first comparison step E140, if the position of the sun S determined, during the third determination step E130, is outside the operating zone F of the illuminance sensor 43, then the method implements an inhibition step E160 of the illuminance sensor 43, so as to prohibit movement of the screen 2 by means of the electromechanical actuator 11, as a function of data coming from the illuminance sensor 43.

Thus, a movement of the screen 2 of the concealment device 3 is prohibited, in other words is not authorized to be executed, in particular temporarily, by means of the electromechanical actuator 11, depending on the data coming from the sensor d illumination 43, given that these are considered to be inconsistent with the expected direct solar radiation, in other words potential, on the window 40.

In addition, the prohibition of or each movement of the screen 2 of the concealment device 3 by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43, in the case where a measurement of sunshine by the illuminance sensor 43 is considered not to be representative of direct solar radiation on the window 40, makes it possible to avoid dissatisfaction of a user and to leave the possibility for the user to carry out a adjustment of the position of the screen 2 of the concealment device 3 by means of the electromechanical actuator 11 by issuing a manual control order, in particular from the local control unit 12, of the central control unit 13 or mobile terminal 33.

In other words, if a manual control order is issued to cause a movement of the screen 2, the data provided by the illuminance sensor 43 are not taken into consideration to define this control order.

More generally, a movement of the screen 2 of the concealment device 3 can still be carried out, without this movement being determined by data coming from the illuminance sensor 43.

In a first exemplary embodiment, the first selection step E150 of the illuminance sensor 43 is implemented only for at least a first time slot of a first predetermined period of time T1, during which the position of the sun S is inside the operating zone F of the illuminance sensor 43. In addition, the inhibition step E160 of the illuminance sensor 43 is implemented for at least a second time slot of the first period of predetermined time T1, during which the position of the sun S is outside the operating zone F of the illuminance sensor 43.

Thus, the method makes it possible to select or inhibit the illuminance sensor 43 for different time slots during the first predetermined period of time T1 to authorize or prohibit movement of the screen 2 of the concealment device 3 by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43.

In a second exemplary embodiment, the first selection step E150 of the illuminance sensor 43 is implemented for the entire duration of a first predetermined period of time T1, if the position of the sun S is inside the operating zone F of the illuminance sensor 43 at a given instant of the first predetermined time period T1. In addition, the inhibition step E160 of the illuminance sensor 43 is implemented for the entire duration of the first predetermined time period T1, if the position of the sun S is outside the operating zone F of the sensor illumination 43 for the entire duration of the first predetermined period of time T1.

Thus, the method makes it possible to select or inhibit the illuminance sensor 43 for the entire first predetermined period of time T1 to authorize or prohibit movement of the screen 2 of the concealment device 3 by means of the electromechanical actuator 11, depending on the data coming from the illuminance sensor 43.

Advantageously, the first predetermined period of time T1 is equivalent to one day, in other words to twenty-four hours.

Alternatively and in the case of the second embodiment, the first predetermined period of time T1 may be equivalent to a duration defined by a number of days, weeks or months.

In a third embodiment, following the first comparison step E140, the method further comprises a fourth determination step E170 for implementing the first selection step E150 or the inhibition step E160 of the illuminance sensor 43, as a function of a duration of a second predetermined period of time T2, during which the position of the sun S is inside the operating zone F of the illuminance sensor 43. The first selection step E150 is implemented if the duration of the second predetermined time period T2, during which the position of the sun S is inside the operating zone F of the illuminance sensor 43, is greater or equal to a first predetermined threshold value S1. In addition, the inhibition step E160 is implemented if the duration of the second predetermined time period T2, during which the position of the sun S is inside the operating zone F of the sun sensor illuminance 43, is less than the first predetermined threshold value S1.

Thus, following the fourth determination step E170, the method makes it possible to determine whether a measurement of sunshine by the illuminance sensor 43 is considered to be representative of direct solar radiation on the window 40 or not, by means of a criterion defined by the duration of the second predetermined period of time T2 during which the position of the sun S is inside the operating zone F of the illuminance sensor 43.

Advantageously, this third embodiment can be implemented during a commissioning phase of the installation 100.

Thus, the terminal 12, 13, 33 can signal to the installer that the illuminance sensor 43 is not relevant or too little relevant over the course of a year at the location planned in relation to the building and that a another location is to be tested, or even to propose another location according to data obtained in a solar mask of the differences obtained by comparison of the first solar mask M1 and a second solar mask M2.

In this way, the method is a tool to assist in the commissioning of the installation 100 comprising the illuminance sensor 43.

Advantageously, the duration of the second predetermined time period T2 corresponds to a minimum number of days during which the position of the sun S is inside the operating zone F of the illuminance sensor 43 for a minimum duration each day. Furthermore, the second predetermined time period T2 is equivalent to one year.

Advantageously, the method further comprises a fifth step of determining E180 an orientation of the window 40 of the building.

Advantageously, the fifth determination step E180 is implemented by means of the orientation detection device 38 of the terminal 12, 13, 33.

Alternatively or in addition, the fifth determination step E180 is implemented by means of the selection elements 14 and display elements 34 of the terminal 12, 13, 33 and/or data transmitted by the server 28 to the second communication module 36 from terminal 12, 13, 33.

Advantageously, the method further comprises a recording step E190 of the orientation of the window 40 of the building determined, during the fifth determination step E180, in particular in a memory of the controller 35 of the terminal 12, 13, 33.

Advantageously, the step E100 of obtaining the geographical location of the installation 100 and the fifth step of determining E180 the orientation of the window 40 of the building make it possible to obtain a virtual illuminance sensor 44, otherwise said characterize a virtual illuminance sensor 44.

Advantageously, obtaining the virtual illuminance sensor 44 is implemented by interrogating, in particular, the server 28. The virtual illuminance sensor 44 is all the means making it possible to simulate a real illuminance sensor and to produce the data that would be produced by the actual illuminance sensor installed in a given location. To do this, the means use meteorological data provided on a network such as the internet.

Advantageously, the sub-step of entering or retrieving E115 of the date and time is also part of the characterization of the virtual illuminance sensor 44.

Advantageously, the method further comprises a sixth determination step E200 of the second solar mask M2 facing the window 40 of the building.

Here, the second solar mask M2 is determined at the center of the window 40 and, more particularly, at the center of the window 42 of the window 40.

The location for determining the second solar mask M2 is not limiting and can be different, as long as it is representative of the window 40. It can, for example, be determined on an edge, in particular, upper, lower or lateral, of the window 40 and, in particular, of the window 42.

Advantageously, the sixth determination step E200 of the second solar mask M2 facing the window 40 comprises sub-steps similar to sub-steps E111, E112, E113, E114, E115, E116, E117, E118, E119 of the first step determination E110 of the first solar mask M1 facing the illuminance sensor 43. The main change is that the sixth determination step E200 is implemented for the location of the window 40 while the first determination step E110 is implemented implemented for the location of the illuminance sensor 43.

Advantageously, the sixth determination step E200 of the second solar mask M2 facing the window 40 of the building is also part of the characterization of the virtual illuminance sensor 44.

Thus, the determination of the second solar mask M2 makes it possible to improve the precision of the virtual illuminance sensor 44.

In a fourth embodiment, depending on the result of the first comparison step E140, if the position of the sun S determined, during the third determination step E130, is outside the operating zone F of the illuminance sensor 43, then the method implements a second selection step E210 of the virtual illuminance sensor 44, so as to authorize movement of the screen 2 by means of the electromechanical actuator 11, as a function of data coming from the virtual sensor lighting 44 selected, during the second selection step E210.

Thus, the method makes it possible to select the illuminance sensor 43 or the virtual illuminance sensor 44 which is the most relevant, in particular temporarily, to execute or not a movement of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11, as a function of the respective data coming from the illuminance sensor 43 or the virtual illuminance sensor 44.

In this way, the selection of the illuminance sensor 43 or the virtual illuminance sensor 44 makes it possible to take advantage of the advantages of each of them at a given moment and to improve the thermal management of the building and/or glare. inside the building and therefore promote user satisfaction.

Advantageously, the method further comprises a step of measuring E230 of at least one value of the physical quantity Ipv, Icc, Upv, Uv delivered by the photovoltaic panel 25 or the illuminance sensor 43.

Advantageously, the method further comprises a seventh determination step E220 of at least one illuminance value L obtained from the virtual illuminance sensor 44.

Thus, the seventh determination step E220 makes it possible to determine whether the sky C is clear or not as a function of the or each illuminance value L determined by the virtual illuminance sensor 44.

Advantageously, the method further comprises a second comparison step E240 of the or each measured value of the physical quantity Ipv, Icc, Upv, Uv delivered by the photovoltaic panel 25 or the illuminance sensor 43, during measuring step E230, relative to the or each illuminance value L determined by the virtual illuminance sensor 44, during the seventh determination step E220.

Advantageously, the method further comprises a third step of comparison E260 of the or each illuminance value L determined by the virtual illuminance sensor 44, during the seventh determination step E220, with respect to at least one value theoretical illuminance E in clear sky conditions C.

Here, the theoretical illuminance value E is defined in the case where the sky C is clear and can take into consideration a tolerance. The illuminance in clear sky conditions C on a horizontal plane is calculated, in particular, as a function of the solar constant, in other words the value of the solar radiation which impacts the Earth before crossing the atmosphere, the atmospheric turbidity and the position of the sun in sky C. In order to know the illuminance in clear sky conditions C on a vertical plane, in particular that of window 40, it is also necessary to know the azimuth of this vertical plane.

Thus, if the or each illuminance value L determined, during the seventh determination step E220, is equal to the theoretical illuminance value E, the sky C is considered to be clear or clear, in other words a beautiful condition. time is determined. Whereas, if the or each illuminance value L determined, during the seventh determination step E220, is less than the theoretical illuminance value E, the sky C is considered to be obstructed, in other words a bad weather condition is determined.

Advantageously:

- depending on the result of the first comparison step E140, if the position of the sun S determined, during the third determination step E130, is within the operating zone F of the illuminance sensor 43,

- depending on the result of the second comparison step E240, if the or each measured value of the physical quantity Ipv, Icc, Upv, Uv delivered by the photovoltaic panel 25 or the illuminance sensor 43, during the step of measurement E230, is less than the or each illuminance value L determined by the virtual illuminance sensor 44, during the seventh determination step E220, and

- depending on the result of the third comparison step E260, if the or each illuminance value L determined, during the seventh determination step E220, is equal to the theoretical illuminance value E in clear sky conditions C,

the method further comprises a signaling step E250 of an operation to be executed.

Advantageously, the or each illuminance value L determined by the virtual illuminance sensor 44, during the seventh determination step E220, can be corrected with a value of a tolerance. Likewise, the theoretical illuminance value E in clear sky conditions C can be corrected with a tolerance value.

Advantageously, the operation to be performed is either an operation of cleaning the photovoltaic panel 25 or the illuminance sensor 43, or an operation of verifying the operation of the photovoltaic panel 25 or the illuminance sensor 43, or a reiteration of the first, second and third determination steps E110, E120, E130, the first comparison step E140 and, optionally, the sixth determination step E200.

Thus, the method also makes it possible to determine if a malfunction or a modification in the performance of the photovoltaic panel 25 or the illuminance sensor 43 has occurred or if an evolution of the other obstacle(s) B linked to another building, which may , for example, to be constructed or destroyed, or to vegetation, which may, for example, have grown or been cut.

Advantageously, the signaling step E250 is implemented by transmitting an alert, a message or a light and/or sound signal from the terminal 12, 13, 33.

Advantageously, the first and second determination steps E110, E120, are implemented in the configuration mode of the motorized drive device 5, preferably only once in this configuration mode. Likewise, the fifth and sixth determination steps E180, E200 are implemented in the configuration mode of the motorized drive device 5, preferably only once in this configuration mode.

Advantageously, the third determination step E120, the first comparison step E140 and the first selection step E150 are implemented in the control mode of the motorized drive device 5, preferably several times and repeatedly, according to a frequency which can be fixed or variable, in this control mode, in particular as a function of a request executed by the controller 35 of the local control unit 12 or the central control unit 13. Likewise, the step inhibition E160, the fourth and seventh determination steps E170, E220 and the second selection step E210 are implemented in the control mode of the motorized drive device 5, preferably several times and repeatedly, according to a frequency which can be fixed or variable, in this control mode, in particular as a function of a request executed by the controller 35 of the local control unit 12 or the central control unit 13.

Advantageously, the first, second and third determination steps E110, E120, E130, the first comparison step E140 and the first selection step E150 are implemented by means of the controller 35 of the terminal 12, 13, 33. Likewise, the inhibition step E160, the fourth, fifth and sixth determination steps E170, E180, E200, the second selection step E210 and the second and third comparison steps E240, E260 are implemented by means of the controller 35 of the terminal 12, 13, 33.

Advantageously, the second communication module 36 of the terminal 12, 13, 33 is configured to communicate with the first communication module 27 of the electronic control unit 15, so as to authorize the movement of the screen 2 by means of the electromechanical actuator 11, as a function of data coming from the illuminance sensor 43 selected, during the first selection step E150.

Advantageously, the movements of the screen 2 by means of the electromechanical actuator 11, as a function of the data coming from the illuminance sensor 43, are implemented in the control mode of the motorized drive device 5.

Thus, the electronic control unit 15 is configured to control, in other words control, the electromechanical actuator 11 or, optionally, a plurality of electromechanical actuators 11, as a function of at least one value of at least one condition d sunshine coming from the illuminance sensor 43, following execution of the operating method, in the case where a measurement of sunshine by the illuminance sensor 43 is considered to be representative of direct solar radiation on the window 40.

In this way, if the illuminance sensor 43 was selected, during the first selection step E150, and the position of the sun S is inside the operating zone F of the illuminance sensor 43, then the movement of the screen 2 by means of the electromechanical actuator 11 is implemented.

Advantageously, the movements of the screen 2 by means of the electromechanical actuator 11, as a function of the data coming from the virtual illuminance sensor 44, are implemented in the control mode of the motorized drive device 5.

Thus, the electronic control unit 15 is configured to control, in other words control, the electromechanical actuator 11 or, optionally, a plurality of electromechanical actuators 11, as a function of at least one value of at least one condition d sunshine coming from the virtual illuminance sensor 44, following execution of the operating method, in the case where a measurement of sunshine determined by the virtual illuminance sensor 44 is considered to be representative of direct solar radiation on window 40.

In this way, if the virtual illuminance sensor 44 has been selected, during the second selection step E210, then the movement of the screen 2 by means of the electromechanical actuator 11 is implemented.

In the preceding description, Figures 5 to 9 are explanatory illustrations of the digital processing carried out. Complementary or alternative digital processing can be implemented. The method which is the subject of the invention may not implement at any time a display of one, some or all of these illustrations.

Thanks to the present invention, the method makes it possible to avoid inappropriate operation of the electromechanical actuator to move the screen of the occultation device opposite the window of the building, as a function of data coming from the sensor illuminance, which is generated by a location of the illuminance sensor not representative of direct solar radiation on the window.

Numerous modifications can be made to the exemplary embodiments described above, without departing from the scope of the invention.

Alternatively, not shown, the superposition substep E118 can be implemented according to a different process.
