Description

Title of the invention: Method of operating a solar screening or protection installation and associated installation

[0001] The present invention relates to a method of operating a solar screening or protection installation.

[0002] The present invention also relates to an installation suitable for implementing this operating method.

[0003] Generally, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and at least a second position.

[0004] A motorized drive device comprises an electromechanical actuator of a mobile occultation or solar protection element, such as a roller shutter, a blind, a curtain, a hinged shutter or any other equivalent material, hereinafter called a screen.

[0005] Document EP 3 904 630 A1 is already known, which describes a solar shading or protection installation comprising a shading device, a window of a building and a lighting sensor. The shading device comprises a screen, a motorized drive device and an electrical power supply device. The screen is configured to move opposite the window of the building. The motorized drive device comprises 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 power supply device. The electrical power supply device comprises a photovoltaic panel and a battery. The photovoltaic panel is electrically connected to the battery.

[0006] This installation is configured to implement a method for controlling the operation of the installation 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 method is generally satisfactory.

[0007] However, this installation has the disadvantage that the occultation device is arranged inside the building and that the photovoltaic panel is fixed to the screen of the occultation device.

[0008] Therefore, the photovoltaic panel may not be exposed to direct solar radiation at least at certain times of a day, because of another shading device arranged outside the building or because the photovoltaic panel can be raised above the window and that it is hidden by a wall of the building.

[0009] Furthermore, this document EP 3 904 630 A1 is silent as to the use of the photovoltaic panel as an illumination sensor.

[0010] Furthermore, this document EP 3 904 630 A1 is silent as to the positioning of the illumination sensor in relation to the installation.

[0011] In the case where the illumination sensor is fixed to the exterior of the building, in particular on a box of another occultation device arranged outside the building or in a remote manner on a wall of the building, this illumination sensor may not be exposed to direct solar radiation at at least certain times of a day, because of an element of the architecture of the building and, more particularly, a window lintel, a roof overhang or a balcony.

[0012] Thus, the illumination sensor may not be relevant, at least occasionally, to authorize or prohibit a movement of the screen of the occultation 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.

[0013] In this way, a movement of the screen of the occulting device may not be executed 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 architecture, such as, for example, a window lintel, a roof overhang or a balcony. And conversely, a movement of the screen of the occulting device may be executed 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 may, in particular, occur when the illumination sensor is used to control a plurality of occultation devices arranged respectively opposite a different window of the same facade of the building.

[0014] 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 the building and therefore cause dissatisfaction of a user.

[0015] The present invention aims to solve the aforementioned drawbacks and to propose a method for operating a blackout or solar protection installation, as well as a blackout or solar protection installation, making it possible to avoid inappropriate operation of an electromechanical actuator for moving a screen of a blackout device opposite a window of a building, based on data from an illuminance sensor, which is generated by a location of the illuminance sensor not representative of direct solar radiation on the window.

[0016] In this regard, the present invention aims, according to a first aspect, at a method of operating a solar occultation or protection installation,

[0023] - a motorized drive device,

[0024] the motorized drive device comprising at least:

[0025] - an electromechanical actuator, the electromechanical actuator being configured to move the screen, and

[0026] - an electronic control unit.

[0027] The method comprises, at least, a first step of determining a first solar mask facing the illumination sensor.

[0028] According to the invention, the method further comprises at least:

[0029] - a second step of determining a second solar mask facing the window of the building,

[0030] - a third step of determining a solar mask of the differences, from of the first solar mask determined, during the first determination step, and of the second solar mask determined, during the second determination step, so as to determine an operating zone of the illumination sensor,

[0031] - a fourth step of determining a position of the sun, in the mask solar of differences, and

[0032] - a first step of comparing the position of the sun determined, during the fourth step of determination, in relation to the operating area of ​​the illumination sensor.

[0033] Furthermore, depending on the result of the first comparison step, if the position of the sun determined, during the fourth determination step, is within the operating zone of the illumination sensor, then the method implements a first step of selecting the illumination sensor, so as to authorize a movement of the screen by means of the electromechanical actuator, depending on data coming from the illumination sensor selected, during the first selection step.

[0034] Thus, the method makes it possible to avoid inappropriate operation of the electromechanical actuator for moving the screen of the occultation device opposite the window of the building, as a function of data coming from the illumination sensor, which is generated by a location of the illumination sensor not representative of direct solar radiation on the window.

[0035] In this way, a movement of the screen of the occulting device is allowed to be executed by means of the electromechanical actuator, depending on the data coming from the illumination sensor, given that these are considered to be consistent with the expected direct solar radiation, in other words potential, on the window.

[0036] According to an advantageous characteristic of the invention, the electronic control unit comprises a first communication module. The installation further comprises a terminal. The terminal comprises at least one controller and a second communication module.

Furthermore, the second communication module of the terminal is configured to communicate with the first communication module of the electronic control unit, so as to authorize the movement of the screen by means of the electromechanical actuator, according to data coming from the selected illumination sensor, during the first selection step.

[0037] According to another advantageous characteristic of the invention, depending on the result of the first comparison step, if the position of the sun determined, during the fourth determination step, is outside the operating zone of the illumination sensor, then the method implements a first step of signaling non-adaptation of the illumination sensor, while implementing the first step of selection of the illumination sensor, so as to authorize a movement of the screen by means of the electromechanical actuator, depending on data coming from the selected illumination sensor, during the first selection step.

[0038] According to another advantageous characteristic of the invention, depending on the result of the first comparison step, if the position of the sun determined, during the fourth determination step, is outside the operating zone of the illumination sensor, then the method implements a step of inhibiting the illumination sensor, so as to prohibit movement of the screen by means of the electromechanical actuator, depending on data coming from the illumination sensor.

[0039] According to a first exemplary embodiment of the invention, the first step of selecting the illumination sensor is implemented only for at least one first time slot of a first predetermined time period, during which the position of the sun is within the operating zone of the illuminance sensor. Furthermore, the step of inhibiting the illuminance sensor is implemented for at least a second time slot of the first predetermined time period, during which the position of the sun is outside the operating zone of the illuminance sensor.

[0040] According to a second exemplary embodiment of the invention, the first step of selecting the illumination sensor is implemented for the entire duration of a first predetermined period of time, if the position of the sun is inside the operating zone of the illumination sensor at a given instant of the first predetermined period of time. Furthermore, the step of inhibiting the illumination sensor is implemented for the entire duration of the first predetermined period of time, if the position of the sun is outside the operating zone of the illumination sensor for the entire duration of the first predetermined period of time.

[0041] According to a third exemplary embodiment of the invention, following the first comparison step, the method further comprises a fifth step of determining the implementation of the first selection step or the step of inhibiting the illumination sensor, as a function of a duration of a second predetermined time period, during which the position of the sun is within the operating zone of the illumination sensor. The first selection step is implemented if the duration of the second predetermined time period, during which the position of the sun is within the operating zone of the illumination sensor, is greater than or equal to a first predetermined threshold value.Furthermore, the inhibition step is implemented if the duration of the second predetermined time period, during which the position of the sun is within the operating area of ​​the illuminance sensor, is less than the first predetermined threshold value.

[0042] Alternatively, the method further comprises at least:

[0043] - a step of obtaining a geographical location of the installation, and

[0044] - a sixth step of determining an orientation of the building window, the obtaining step and the sixth determination step allowing the obtaining of a virtual illumination sensor.

[0045] Furthermore, depending on the result of the first comparison step, if the position of the sun determined, during the fourth determination step, is outside the operating zone of the illumination sensor, then the method implements a second step of selection of the virtual illumination sensor, so as to authorize a movement of the screen by means of the electromechanical actuator, depending on data from the selected virtual illuminance sensor, during the second selection step.

[0046] According to another advantageous characteristic of the invention, the electronic control unit of the motorized drive device or a controller of the illumination sensor comprises a device for measuring a physical quantity delivered by the illumination sensor, the physical quantity being representative of sunlight of the illumination sensor.

[0047] The method further comprises at least:

[0048] - a step of measuring at least one value of the physical quantity delivered by the illumination sensor,

[0049] - a seventh step of determining at least one illumination value by the virtual illumination sensor, and

[0050] - a second step of comparing the or each measured value of the quantity physical delivered by the illumination sensor, during the measurement step, in relation to the or each illumination value determined by the virtual illumination sensor, during the seventh determination step, and

[0051] - a third step of comparing the or each illumination value completed by the virtual illuminance sensor, during the seventh determination step, in relation to at least one theoretical illuminance value in clear sky conditions.

[0052] Furthermore,

[0053] - depending on the result of the first comparison step, if the position of the sun determined, during the fourth determination step, is within the operating area of ​​the illumination sensor,

[0054] - depending on the result of the second comparison step, if the or each value measured value of the physical quantity delivered by the illumination sensor, during the measurement step, is less than the or each illumination value determined by the virtual illumination sensor, during the seventh determination step, and

[0055] - depending on the result of the third comparison step, if the or each value of illumination determined, during the seventh determination step, is equal to the theoretical value of illumination in clear sky conditions,

[0076] Advantageously, the window 42 can either be mounted in the fixed frame 41, in the case where it is fixed relative to the fixed frame 41, or mounted in a frame of the opening, in the case where it is movable relative to the fixed frame 41, in particular according to a rotational movement, in particular in the case of a tilting or swinging window, or according to a translational movement, in particular in the case of a sliding window in a horizontal or vertical direction, or according to two rotational movements, in particular in the case of a tilt-and-turn window.

[0077] The closing, concealing or solar protection device 3 is hereinafter called a “concealing device”. The concealing device 3 comprises the screen 2. The screen 2 is configured to move opposite the window 40 of the building, i.e. to cover the window 40 in a deployed configuration.

[0078] The occultation device 3 may be a roller shutter, a canvas blind or one with adjustable slats, a rolling gate, a grille, a door or even a hinged shutter. The present invention applies to all types of occultation device.

In addition, the lower unrolled position corresponds to the support of the final end blade 8 of the apron 2 of the roller shutter 3 against a threshold 7 of the opening 1 or to the stopping of the final end blade 8 in a programmed lower end-of-travel position.

[0256] - a sub-step El 11 of positioning the mobile terminal 33 at the location of the illumination sensor 43 compared to installation 100,

[0257] - following the positioning sub-step El 11, a taking sub-step El 12 of at least at least one photograph P, using the camera 37 of the mobile terminal 33, and

[0258] - a first sub-step of determining El 13 an orientation of the camera topographic 37 of the mobile terminal 33, during the sub-step E1 12 of taking the photograph P, by means of the orientation detection device 38 and the controller 35 of the mobile terminal 33.

[0259] Here, the first determination sub-step E1 13 makes it possible to determine an orientation of the camera 37 of the mobile terminal 33 relative to a reference frame R and, possibly, an inclination of the camera 37 of the mobile terminal 33 relative to the ground and / or an attitude of the camera 37 of the mobile terminal 33, i.e. a rotation relative to each of the axes X, Y, Z of a three-dimensional reference frame.

[0260] Advantageously, the first determination step El 10 further comprises, following the taking sub-step El 12, a second determination sub-step El 14 of at least one sky zone C from the photograph P, taken during the taking sub-step El 12, by means of the controller 35 of the mobile terminal 33.

[0261] Advantageously, the second determination sub-step E1 14 comprises a first image processing.

[0262] Advantageously, the first image processing, during the second determination sub-step E1 14, is implemented by the controller 35 of the terminal 12, 13, 33, in particular by means of software embedded in the controller 35 of the terminal 12, 13, 33.

[0263] An example of the result of the first image processing of photograph P is illustrated in [Fig.5]. Here, the white part of [Fig.5] corresponds to the sky area C.

[0264] Advantageously, the first image processing, during the second determination sub-step E1 14, consists of carrying out a binary segmentation of the photograph P to separate the sky C from the other elements of the photograph P.

[0265] In an exemplary embodiment, such a binary segmentation of the photograph P consists of evaluating a radiometry, in particular of the RGB type (acronym for the English 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 brightness gradient is high and, in particular, greater than a predetermined threshold, this may correspond to a boundary between the sky C and another element of the photograph P.

[0266] Advantageously, the photograph P, taken during the taking sub-step El 12, 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 the other pixels are converted into black pixels, corresponding to a second binary state assigned, for example, to a value “1”.

[0267] Advantageously, the first determination step El 10 comprises a sub-step El 15 of entering or retrieving the date and time during the taking sub-step El 12.

[0268] Here, the input or recovery sub-step El 15 is implemented by means of the controller 35 of the terminal 12, 13, 33.

[0269] Alternatively or in addition, the entry or retrieval sub-step E1 15 is implemented through the selection 14 and display 34 elements 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.

[0270] Advantageously, the first determination step El 10 comprises a second sub-step El 16 of recording the date and time entered or retrieved, during the entry or retrieval sub-step El 15, in particular in a memory of the controller 35 of the terminal 12, 13, 33.

[0271] 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 English term “Real Time Clock”). Such a clock can be integrated into the controller 35 of the terminal 12, 13, 33.

[0272] Advantageously, the first determination step El 10 further comprises, following the first determination sub-step El 13, a projection sub-step El 17 of data from the photograph P, taken during the taking sub-step El 12, in a projection reference frame V.

[0273] Here, the projection sub-step El 17 is implemented by means of the controller 35 of the terminal 12, 13, 33.

[0274] An example of the result of the projection of the data of the photograph P into the projection frame V is illustrated in [Fig.6].

[0275] Advantageously, the projection sub-step El 17 is implemented as a function of orientation data of the camera 37 of the mobile terminal 33, determined during the first determination sub-step El 13, which may be angles defining, in particular, a precession, in other words a pitch, a nutation, in other words a roll, and a proper rotation, in other words a yaw. Such angles are commonly called Euler angles.

[0276] Here, the projection sub-step El 17 corresponds to a step of changing the reference frame of the data of the photograph P, in particular from the reference frame R, for example cardinal, to the projection reference frame V and, more particularly, from a three-dimensional reference frame mental centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33 towards the projection mark V.

[0277] Advantageously, the projection reference frame V is a reference frame in which angular coordinates of azimuth and elevation are represented. In [Fig.6], the azimuth is represented on the abscissa and the elevation is represented on the ordinate, in an orthogonal Cartesian reference frame.

[0278] Advantageously, the projection reference mark V of the photograph P, taken during the taking sub-step E1 12, is a spherical reference mark of the celestial vault.

[0279] The angles, 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 photographic apparatus 37 of the mobile terminal 33, relative to a Cartesian reference frame, in other words a three-dimensional reference frame, in particular the reference frame R, which can also be called a cardinal reference frame.

[0280] 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 elevation angle is assimilated to a precession angle in the reference frame R.

[0281] Advantageously, the sub-step El 17 of projecting the data of the photograph P, taken during the sub-step El 12 of taking, is implemented, in addition, as a function of a focal length of a lens of the photographic apparatus 37 of the mobile terminal 33.

[0282] Advantageously, the sub-step El 17 of projecting the data of the photograph P, taken during the sub-step El 12 of taking, is implemented, in addition, as a function of the dimensions of an image sensor of the photographic apparatus 37 of the mobile terminal 33, in other words the horizontal and vertical field angles of the photographic apparatus 37 of the mobile terminal 33.

[0283] In an exemplary embodiment, the projection sub-step El 17, in the projection frame V, comprises a first sub-step of passing the data of the photograph P from a first three-dimensional frame centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33 to a second three-dimensional frame 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 El 17 requires beforehand 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 image sensor of the camera 37 of the mobile terminal 33.This first sub-step of the projection sub-step El 17 thus makes it possible to obtain a result comprising three matrices, each expressing a coordinate of each pixel of the photograph P. along the X, Y, Z axes of the second three-dimensional reference frame. In addition, the projection sub-step El 17, 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 El 17 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 El 17 requires first determining each angle, called Euler angle, during the first determination sub-step El 13, and applying 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 El 17 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.

[0284] Advantageously, the projection sub-step El 17 is implemented as a function of the determined orientation of the camera 37 of the mobile terminal 33, during the first determination sub-step El 13, of the focal length of the lens of the camera 37 of the mobile terminal 33, of the dimensions of the image sensor of the camera 37 of the mobile terminal 33 and of at least one angle, called Euler angle, determined, during the first determination sub-step El 13. The at least one of the angles, called Euler angles, to be taken into consideration is, in particular, the at least one of the angles called proper rotation, precession and nutation and, preferably, the set of angles, called Euler angles.

[0285] Advantageously, the first determination step El 10 further comprises, following the first determination sub-step El 13, in particular following the projection sub-step El 17, a superposition sub-step El 18 of data from the photograph P, taken during the taking sub-step El 12, in particular from the photograph Pp, projected during the projection sub-step El 17, on a solar path diagram, in the reference frame R, in particular in the projection reference frame V, so as to determine the first solar mask M1 at the location of the illumination sensor 43.

[0286] The solar path diagram, also called a solar diagram, is a diagram indicating, at different times of the year, an angular height, also called an angle or elevation height, 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 illumination sensor 43 relative to the installation 100 for different times, during the year. In this way, the solar path diagram makes it possible to define times during which direct incident solar radiation exists at the location of the illumination 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.

[0287] 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 given date of the year.

[0288] Here, the solar path diagram is determined in the projection frame V.

[0289] Here, the superposition sub-step El 18 is implemented by means of the controller 35 from terminal 12, 13, 33.

[0290] The superposition of the data of the photograph P, taken during the taking sub-step El 12, in particular of the photograph Pp, projected during the projection sub-step El 17, on the solar path diagram, in the reference frame R, in particular in the projection reference frame V, thus makes it possible to determine at each instant, in particular during the year, whether the sun is visible or not at the location of the illumination sensor 43 relative to the installation 100.

[0291] In order to implement the superposition sub-step El 18, 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 frame of reference, in other words in a common frame of reference.

[0292] The common reference point may be, in particular, a cardinal reference point, a three-dimensional reference point centered on a midpoint of the image sensor of the photographic camera 37 of the mobile terminal 33, a three-dimensional reference point centered on a focal point of the lens of the photographic camera 37 of the mobile terminal 33 or a spherical reference point of the celestial vault, also called a projection reference point.

[0293] Here, the superposition sub-step El 18 is implemented from data of the photograph Pp, projected during the projection sub-step El 17, onto 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 El 12.

[0294] Advantageously, the first determination step El 10 comprises a third sub-step El 19 of recording data defining the photograph P, taken during the taking sub-step El 12, and, possibly, the photograph Pp, projected during the projection sub-step El 17, in a memory of the controller 35 of the terminal 12, 13, 33.

[0295] Here, the projection and superposition sub-steps El 17, El 18 are obtained by geometric operations. The projection and superposition sub-steps El 17, El 18 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 ML

[0296] The calculation sub-steps of the first determination step E1 10 have been described as being implemented in the terminal 12, 13, 33. However, these calculation sub-steps may alternatively be implemented partially or fully. in server 28.

[0297] The method further comprises a second step E120 of determining a second solar mask M2 facing the window 40 of the building.

[0298] Here, the second solar mask M2 is determined at the center of the window 40 and, more particularly, at the center of the glass 42 of the window 40.

[0299] The location for determining the second solar mask M2 is not limiting and may be different, as long as it is representative of the window 40. It may, for example, be determined on an edge, in particular, upper, lower or lateral, of the window 40 and, in particular, of the window 42.

[0300] Advantageously, the second step of determining El20 the second solar mask M2 facing the window 40 comprises sub-steps similar to the sub-steps El 11, El 12, El 13, El 14, El 15, El 16, El 17, El 18, El 19 of the first step of determining El 10 the first solar mask M1 facing the illumination sensor 43. The main change is that the second step of determining E120 is implemented for the location of the window 40 while the first step of determining El 10 is implemented for the location of the illumination sensor 43.

[0301] The method further comprises a third step E130 of determining a solar mask of the differences Ml-2, from the first solar mask Ml determined, during the first step of determination El 10, and from the second solar mask M2 determined, during the second step of determination El20, so as to determine an operating zone F of the illumination sensor 43.

[0302] The photograph P taken during the taking sub-step El 12 during the first determination step El 10, as well as that taken during the taking sub-step during the second determination step E120 consists of a plurality of pixels, as described previously, arranged in the form of a matrix comprising rows and columns.

[0303] Advantageously, the third determination step El30 comprises a second image processing consisting of combining the first solar mask M1 determined, during the first determination step El 10, and the second solar mask M2 determined, during the second determination step El20.

[0304] Advantageously, the second image processing, during the third determination step E130, is implemented by the controller 35 of the terminal 12, 13, 33, in particular by means of software embedded in the controller 35 of the terminal 12, 13, 33.

[0305] An example of the result of the second image processing is illustrated in [Fig.9]. Here, the gray part of [Fig.9] corresponds to the operating zone F of the illumination sensor 43, in other words to a so-called “relevance” zone thereof.

[0306] Advantageously, the second image processing, during the third determination step El30, consists of determining a binary state of the pixels of the matrix forming the solar mask of the differences Ml-2 from the first solar mask Ml and the second solar mask M2.

[0307] In the exemplary embodiment, the third determination step E130 comprises:

[0308] - a comparison sub-step E131 of the binary state of each pixel of the matrix representative of the first solar mask M1 and of the matrix representative of the second solar mask M2, by scanning each line of pixels;

[0309] - if the binary state of the same pixel of the matrix representing the first mask solar Ml, as illustrated in [Fig.6], and the matrix representative of the second solar mask M2, as illustrated in [Fig.8], is identical, this pixel is assigned to a first binary state, that is to say to a value “1”, in other words to a black color, during an assignment sub-step E132. This pixel is considered to be part of the operating zone F of the illumination sensor 43, as illustrated in [Fig.9]; and

[0310] - if the binary state of the same pixel of the matrix representing the first mask solar mask M1 and the matrix representing the second solar mask M2 is different, this pixel is assigned to a second binary state, that is to say to a value “0”, in other words to the color gray, during the assignment sub-step El32. This pixel is considered to be outside the operating zone F of the illumination sensor 43, in other words not forming part of the operating zone F of the illumination sensor 43.

[0311] Thus, all the black-colored pixels, in other words associated with the first binary state, are considered as being part of the operating zone F of the illumination sensor 43 and all the gray-colored pixels, in other words associated with the second binary state, are considered as not being part of the operating zone F of the illumination sensor 43.

[0312] In this way, the operating zone F of the illumination sensor 43 is defined by the set of black pixels, in other words associated with the first binary state, of the matrix representing the solar mask of the differences Ml-2, obtained following the second image processing.

[0313] The second image processing for obtaining the solar mask of the differences Ml-2 makes it possible, in particular, to take into consideration the occurrence of situations where, even if the illumination sensor 43 is not directly illuminated by the sun, the data provided by the illumination sensor 43 can be used to define commands for controlling the movement of the screen 2.

[0314] The method comprises a fourth step E140 of determining a position of the sun S, in the solar mask of the differences Ml-2.

[0315] Advantageously, the fourth determination step E140 is implemented from the date and time entered or retrieved, in particular as described previously during the entry or retrieval sub-step E115, and from the geographical location of the installation 100 obtained, during the obtaining step E100, in particular through the solar path diagram. The recovery of the date and time can be implemented, for example, via the data provided by the clock.

[0316] Advantageously, the fourth determination step E140 comprises sub-steps of calculating data on the position of the sun S in an ecliptic coordinate frame, of converting this data into an equatorial coordinate frame and then into a horizontal coordinate frame, from the date and time entered or retrieved, in particular as described previously during the entry or retrieval sub-step E115, and from the geographical location of the installation 100 obtained, during the obtaining step E100.

[0317] The method further comprises a first comparison step E150 of the position of the sun S determined, during the fourth determination step E140, with respect to the operating zone F of the illumination sensor 43.

[0318] Depending on the result of the first comparison step E150, if the position of the sun S determined, during the fourth determination step E140, is within the operating zone F of the illumination sensor 43, as illustrated in [Fig. 10], then the method implements a first selection step E160 of the illumination sensor 43, so as to authorize a movement of the screen 2 by means of the electromechanical actuator 11, depending on data coming from the illumination sensor 43 selected, during the first selection step El60.

[0319] Thus, the method makes it possible to avoid inappropriate operation of the electromechanical actuator 11 to move the screen 2 of the occultation device 3 opposite the window 40 of the building, as a function of data coming from the illumination sensor 43, which is generated by a location of the illumination sensor 43 not representative of direct solar radiation on the window 40.

[0320] In this way, a movement of the screen 2 of the occulting device 3 is allowed to be executed by means of the electromechanical actuator 11, depending on the data coming from the illumination sensor 43, given that these are considered to be consistent with the expected direct solar radiation, in other words potential, on the window 40.

[0321] In other words, a movement of the screen 2 of the occulting device 3 is allowed to be executed by means of the electromechanical actuator 11, depending on the data coming from the illumination sensor 43, only when the position of the sun S is inside the operating zone F of the illumination sensor 43.

[0322] Furthermore, the authorization of the or each movement of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11, as a function of the data coming from the illumination sensor 43, in the case where a measurement of sunlight by the illumination 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 the glare inside the building and therefore to promote user satisfaction.

[0323] Furthermore, depending on the result of the first comparison step E150, if the position of the sun S determined, during the fourth determination step E140, is outside the operating zone F of the illumination sensor 43, in other words in a zone of difference between the first and second solar masks M1, M2, that is to say where the pixel or pixels of the matrix representative of the solar mask of the differences M1-2 are associated with the second binary state, then the illumination sensor 43 is considered as irrelevant at this given instant and for this position of the sun S, to authorize a movement of the screen 2 by means of the electromechanical actuator 11, depending on data coming from the illumination sensor 43.

[0324] Advantageously, depending on the result of the first comparison step E150, if the position of the sun S determined, during the fourth determination step E140, is outside the operating zone F of the illumination sensor 43, then the method implements a first signaling step E170 of non-adaptation of the illumination sensor 43, while implementing the first selection step E160 of the illumination sensor 43, so as to authorize a movement of the screen 2 by means of the electromechanical actuator 11, depending on data coming from the illumination sensor 43 selected, during the first selection step E160.

[0325] Alternatively, depending on the result of the first comparison step E150, if the position of the sun S determined, during the fourth determination step E140, is outside the operating zone F of the illumination sensor 43, then the method implements a step of inhibition E180 of the illumination sensor 43, so as to prohibit a movement of the screen 2 by means of the electromechanical actuator 11, depending on data coming from the illumination sensor 43.

[0326] Thus, a movement of the screen 2 of the occultation device 3 is prohibited, in other words is not authorized to be executed, in particular temporarily, by means of the electromechanical actuator 11, according to the data coming from the illumination sensor 43, given that these are considered to be inconsistent with the expected direct solar radiation, in other words potential, on the window 40.

[0327] Furthermore, the prohibition of the or each movement of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11, depending on the data from the illumination sensor 43, in the case where a measurement of sunlight by the illumination 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 to the user to carry out an adjustment of the position of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11 by the emission of a manual control order, in particular from the local control unit 12, the central control unit 13 or the mobile terminal 33.

[0328] In other words, if a manual control order is issued to cause a movement of the screen 2, the data provided by the illumination sensor 43 are not taken into consideration to define this control order.

[0329] More generally, a movement of the screen 2 of the occultation device 3 can still be executed, without this movement being determined by data coming from the illumination sensor 43.

[0330] In a first exemplary embodiment, the first selection step E160 of the illumination sensor 43 is implemented only for at least a first time slot of a first predetermined time period T1, during which the position of the sun S is inside the operating zone F of the illumination sensor 43. Furthermore, the inhibition step E180 of the illumination sensor 43 is implemented for at least a second time slot of the first predetermined time period T1, during which the position of the sun S is outside the operating zone F of the illumination sensor 43.

[0331] Thus, the method makes it possible to select or inhibit the illumination sensor 43 for different time slots during the first predetermined time period T1 to authorize or prohibit a movement of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11, depending on the data coming from the illumination sensor 43.

[0332] In a second exemplary embodiment, the first selection step E160 of the illumination sensor 43 is implemented for the entire duration of a first predetermined time period T1, if the position of the sun S is inside the operating zone F of the illumination sensor 43 at a given instant of the first predetermined time period T1. Furthermore, the inhibition step E180 of the illumination 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 illumination sensor 43 for the entire duration of the first predetermined time period T1.

[0333] Thus, the method makes it possible to select or inhibit the illumination sensor 43 for the entire first predetermined time period T1 to authorize or prohibit a movement of the screen 2 of the occultation device 3 by means of the electromechanical actuator 11, as a function of the data coming from the illumination sensor 43.

[0334] Advantageously, the first predetermined period of time T1 is equivalent to one day, in other words to twenty-four hours.

[0335] Alternatively and in the case of the second exemplary embodiment, the first predetermined time period T1 may be equivalent to a duration defined by a number of days, weeks or months.

[0336] In a third exemplary embodiment, following the first comparison step E150, the method further comprises a fifth determination step E190 of implementation of the first selection step E160 or of the inhibition step E180 of the illumination sensor 43, as a function of a duration of a second predetermined time period T2, during which the position of the sun S is within the operating zone F of the illumination sensor 43. The first selection step E160 is implemented if the duration of the second predetermined time period T2, during which the position of the sun S is within the operating zone F of the illumination sensor 43, is greater than or equal to a first predetermined threshold value SI.Furthermore, the inhibition step E180 is implemented if the duration of the second predetermined time period T2, during which the position of the sun S is within the operating zone F of the illumination sensor 43, is less than the first predetermined threshold value SI.

[0337] Thus, following the fifth determination step E190, the method makes it possible to determine whether a measurement of sunshine by the illumination 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 time period T2 during which the position of the sun S is inside the operating zone F of the illumination sensor 43.

[0338] 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 within the operating zone F of the illumination sensor 43 for a minimum duration each day. Furthermore, the second predetermined time period T2 is equivalent to one year.

[0339] Advantageously, this third exemplary embodiment can be implemented during a commissioning phase of the installation 100.

[0340] Thus, the terminal 12, 13, 33 can signal to the installer that the illumination sensor 43 is not relevant or not relevant enough over the course of a year at the location planned in relation to the building and that another location is to be tested, or even to suggest another location to him based on the data obtained in the solar mask of the differences Ml-2.

[0341] In this way, the method is a tool for assisting in the commissioning of the installation 100 comprising the illumination sensor 43.

[0342] Advantageously, the method further comprises a sixth step E200 of determining an orientation of the window 40 of the building.

[0343] Advantageously, the sixth determination step E200 is implemented by means of the orientation detection device 38 of the terminal 12, 13, 33.

[0344] Alternatively or in addition, the sixth determination step E200 is implemented by means of the selection 14 and display 34 elements 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.

[0345] Advantageously, the method further comprises a step E210 of recording the orientation of the window 40 of the building determined, during the sixth determination step E200, in particular in a memory of the controller 35 of the terminal 12, 13, 33.

[0346] Advantageously, the step E100 of obtaining the geographical location of the installation 100 and the sixth step E200 of determining the orientation of the window 40 of the building make it possible to obtain a virtual illumination sensor 44, in other words characterize a virtual illumination sensor 44.

[0347] Advantageously, obtaining the virtual illumination sensor 44 is implemented by interrogating, in particular, the server 28. The virtual illumination sensor 44 is the set of means making it possible to simulate a real illumination sensor and to produce the data which would be produced by the real illumination sensor installed in a given location. To do this, the means use meteorological data provided on a network such as the Internet.

[0348] Advantageously, the sub-step E1 15 of entering or retrieving the date and time is also part of the characterization of the virtual illumination sensor 44.

[0349] Advantageously, the second step of determining El20 of the second solar mask M2 facing the window 40 of the building is also part of the characterization of the virtual illumination sensor 44.

[0350] Thus, the determination of the second solar mask M2 makes it possible to improve the precision of the virtual illumination sensor 44.

[0351] In a fourth exemplary embodiment, depending on the result of the first comparison step E150, if the position of the sun S determined, during the fourth determination step El20, is outside the operating zone F of the illumination sensor 43, then the method implements a second selection step E220 of the virtual illumination sensor 44, so as to authorize a movement of the screen 2 by means of the electromechanical actuator 11, depending on data coming from the virtual illumination sensor 44 selected, during the second selection step E220.

[0352] Thus, the method makes it possible to select the illumination sensor 43 or the virtual illumination 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, according to the respective data coming from the illumination sensor 43 or the virtual illumination sensor 44.

[0353] In this way, the selection of the illumination sensor 43 or the virtual illumination sensor 44 makes it possible to take advantage of the benefits of each of them at a given moment and to improve the thermal management of the building and / or the glare inside the building and therefore to promote user satisfaction.

[0354] Advantageously, the method further comprises a step E230 of measuring at least one value of the physical quantity Ipv, Icc, Upv, Uv delivered by the photovoltaic panel 25 or the illumination sensor 43.

[0355] Advantageously, the method further comprises a seventh step E250 of determining at least one illumination value L obtained from the virtual illumination sensor 44.

[0356] Thus, the seventh determination step E250 makes it possible to determine whether the sky C is clear or not as a function of the or each illumination value L determined by the virtual illumination sensor 44.

[0357] 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 illumination sensor 43, during the measurement step E230, with respect to the or each illumination value L determined by the virtual illumination sensor 44, during the seventh determination step E250.

[0359] Here, the theoretical illumination value E is defined in the case where the sky C is clear and can take into consideration a tolerance. The illumination 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 the sky C. In order to know the illumination in clear sky conditions C on a vertical plane, in particular that of the window 40, it is also necessary to know the azimuth of this vertical plane.

[0360] Thus, if the or each illumination value L determined, during the seventh step of determination E250, is equal to the theoretical illuminance value E, the sky C is considered to be clear or unobstructed, in other words a good weather condition is determined. Whereas, if the or each illuminance value L determined, during the seventh determination step E250, is lower than the theoretical illuminance value E, the sky C is considered to be obstructed, in other words a bad weather condition is determined.

[0361] Advantageously:

[0362] - depending on the result of the first comparison step El50, if the position of the sun S determined, during the fourth determination step E140, is within the operating zone F of the illumination sensor 43,

[0364] - depending on the result of the third comparison step E260, if the or each illumination value L determined, during the seventh determination step E250, is equal to the theoretical illumination value E in clear sky conditions C,

[0365] the method further comprises a second step E270 of signaling an operation to be executed.

[0366] Advantageously, the or each illumination value L determined by the virtual illumination sensor 44, during the seventh determination step E250, can be corrected with a tolerance value. Similarly, the theoretical illumination value E in clear sky conditions C can be corrected with a tolerance value.

[0367] Advantageously, the operation to be performed is either an operation of cleaning the photovoltaic panel 25 or the illumination sensor 43, or an operation of verifying the operation of the photovoltaic panel 25 or the illumination sensor 43, or a reiteration of the first, second, third and fourth determination steps E110, E120, E130, E140 and of the first comparison step E150.

[0368] Thus, the method also makes it possible to determine whether a malfunction or a modification in the performance of the photovoltaic panel 25 or of the illumination sensor 43 has occurred or whether a change in the obstacle(s) linked to another building, which may, for example, be built or destroyed, or to vegetation, which may, for example, have grown or been cut.

Similarly, the inhibition step E160, the fifth and seventh determination steps E190, E250 and the second selection step E220 are implemented in the control mode of the motorized drive device 5, preferably several times and repeatedly, according to a frequency that 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 of the central control unit 13..

[0372] Advantageously, the first, second, third and fourth determination steps E110, E120, E130, E140, the first comparison step E150 and the first selection step E160 are implemented by means of the controller 35 of the terminal 12, 13, 33. Similarly, the inhibition step E180, the fifth, sixth and seventh determination steps E190, E200, E250, the second selection step E220 and the third comparison step E260 are implemented by means of the controller 35 of the terminal 12, 13, 33.

[0373] 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 selected illumination sensor 43, during the first selection step E160.

[0374] Advantageously, the movements of the screen 2 by means of the electromechanical actuator 11, as a function of the data coming from the illumination sensor 43, are implemented in the control mode of the motorized drive device 5.

[0376] In this way, if the illumination sensor 43 has been selected, during the first selection step E160, and the position of the sun S is within the operating zone F of the illumination sensor 43, then the movement of the screen 2 by means of the electromechanical actuator 11 is implemented.

[0377] Advantageously, the movements of the screen 2 by means of the electromechanical actuator 11, as a function of the data coming from the virtual illumination sensor 44, are implemented in the control mode of the motorized drive device 5.
