[0001] The present invention relates to a method for determining the operating state of a motorized drive device of a blackout device for a blackout installation, as well as a mobile terminal adapted to implement this method for determining the operating state of the motorized drive device.

[0002] In general, the present invention relates to the field of blackout devices comprising a motorized drive device moving a screen, between at least a first position and at least a second position.

[0003] A motorized drive device includes an electromechanical actuator of a movable closing, obscuring or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter referred to as a screen.

[0004] EP 3 904 630 A1, which describes a shading system comprising a building, a window, and a shading device, is already known. The building includes a wall. The wall includes an opening. The window is housed within the opening in the wall. The shading device includes a housing, a screen, and a motorized drive system. The screen is configured to be positioned opposite the window so as to partially or completely block the opening in the wall. The motorized drive system includes an electromechanical actuator, an electronic control unit, and an electrical power supply. The screen is configured to be driven in motion by the electromechanical actuator. The electromechanical actuator includes an electric motor. The electrical power supply system includes a battery and a photovoltaic panel.The electronic control unit and the electric motor are powered by the battery.

[0005] Document EP 3 904 630 A1 also describes a method for controlling the operation of the shading system. The method is implemented partly using a mobile terminal. The method includes a step of determining the geographical location of the shading system, a step of determining the orientation of the window, and a step of determining a solar shading, using a controller on the mobile terminal, for a given location. of the photovoltaic panel in relation to the opening in the building wall. This method is generally satisfactory.

[0006] However, this method of controlling the operation of the shading system has the disadvantage of being silent on determining the operating state of the motorized drive device and, more particularly, the operating time of the battery.

[0007] Thus, this method does not allow for the provision of precise and simple information about the operating state of the motorized drive device and, more particularly, about the operating time of the battery or the battery autonomy, when the battery is not supplied with electrical energy by the photovoltaic panel due to zero or insufficient solar input.

[0008] In addition, some manufacturers present the characteristics of their motorized drive devices, such as those described in document EP 3 904 630 Al, in particular a battery life value or a battery autonomy value, in relation to the worst use cases, for a geographical area and for a range of motorized drive devices comprising respectively an electromechanical actuator, a battery and a photovoltaic panel.

[0009] Furthermore, other manufacturers present the characteristics of their motorized drive devices in relation to the most advantageous use cases.

In this case, the orientation and, more particularly, the azimuth is provided by an application software of the mobile terminal 33 using signals delivered by the orientation detection device 38 of the mobile terminal 33.

[0270] Alternatively, the orientation and, more specifically, the azimuth of wall W of building B with respect to the cardinal reference frame is entered directly by the user, using the selection elements 14 and display 34 of the mobile terminal 33, when the mobile terminal 33 is not equipped with the orientation detection device 38 or for the purpose of redundancy, so as to confirm the orientation and, more specifically, the azimuth of wall W provided by the mobile terminal 33. Advantageously, this confirmation can compensate for poor calibration and / or low accuracy of the orientation detection device 38 of the mobile terminal 33 and / or a measurement error due to the presence of an element interfering with the measurement of the Earth's magnetic field by the orientation detection device 38 of the mobile terminal 33, such as a magnet or any other magnetic element.

[0271] In another embodiment, the second communication module 36 of the mobile terminal 33 queries, via a communication protocol, a web service on the server 28, so as to obtain one or more data points relating to the orientation and, more specifically, the azimuth of wall W of building B with respect to the cardinal direction. This or these data points relating to the orientation and, more specifically, the azimuth of wall W may originate, for example, from signals delivered by the positioning device 39 of the mobile terminal 33 or from location data entered by the user, such as a city name and / or a city postal code. In return, the second communication module 36 of the mobile terminal 33 may receive data representing a satellite view corresponding to the data relating to the orientation and, more specifically, the azimuth of wall W, and transmit them to the display element 34 of the mobile terminal 33.Following the display of the satellite view on the display element 34 of the mobile terminal 33, the user is prompted to indicate the geographical location of the shading installation 100 and to select a house and a wall W of that house, including the opening 1 and the window 40. This selection can, for example, be made from the satellite view by drawing a line on a representation of the wall W of building B on the display element 34 of the mobile terminal 33, using their finger or a stylus. In turn, the controller 35 of the mobile terminal 33 calculates the orientation and, more specifically, the azimuth of the wall W with respect to the cardinal direction. Advantageously, this variant can allow the orientation and, more specifically, the azimuth of the wall W to be obtained automatically using the mobile terminal 33, which may not include the orientation detection device 38. Furthermore, this variant can be used to verify data. provided by the orientation detection device 38 or, possibly, to calibrate it.

[0272] Advantageously, the method further comprises an eighth substep of recording E211 the orientation of the wall W of the building B determined, in particular in a memory of the controller 35 of the mobile terminal 33.

[0273] The method further includes a determination step E220 of a solar mask M, using the controller 35 of the mobile terminal 33, for the location of the photovoltaic panel 25 relative to the opening 1 of the wall W of the building B, hereafter referred to as the third determination step E220. The solar mask M for the location of the photovoltaic panel 25 can be called the first solar mask.

[0274] Advantageously, the solar mask M is determined from one or more obstacles arranged opposite the photovoltaic panel 25 and capable of causing a shadow on it with respect to the sun, in particular in the assembled configuration of the shading installation 100, at a given moment, in particular during a year.

[0275] This or these obstacles may be, for example, a building, which may be, in particular, a house or an apartment building, vegetation, which may be, in particular, a shrub or a tree, and / or a landscape feature around the shading installation 100, which may be, in particular, a mountain.

[0276] This or these obstacles defining the solar mask M can reduce, or even stop, the production of electrical energy by the photovoltaic panel 25, from energy inputs from the sun.

[0277] The solar mask M, which can also be called a shading mask, is thus a representation of elements projecting, according to the direction defined in abscissa and ordinate, a shadow at the location of the photovoltaic panel 25 relative to the shading installation 100.

[0278] Here, the location of the photovoltaic panel 25 in relation to the shading installation 100 corresponds to a location from which the solar mask M is to be determined in order to allow a compatibility check of the motorized drive device 5 according to the solar energy inputs supplied to the photovoltaic panel 25 at a given time and, more particularly, during the year.

[0279] In other words, the location of the photovoltaic panel 25 in relation to the shading installation 100 corresponds to a location where the photovoltaic panel 25 is to be positioned in the shading installation 100 to allow a supply of electrical energy to the motorized drive device 5 and, more particularly, to the battery 24 and the electromechanical actuator 11.

[0280] Advantageously, the third determination step E220 includes a substep of positioning E221 of the mobile terminal 33 at the location of the photovoltaic panel 25 relative to the opening 1 of the wall W of the building B. In addition, following the positioning substep E221, the third determination step E220 includes a substep of taking E222 at least one photograph P, using the camera 37 of the mobile terminal 33.

[0281] Thus, the positioning substep E221 consists of placing the mobile terminal 33 at the location where the photovoltaic panel 25 is to be installed, in the assembled configuration of the shading installation 100.

[0282] Advantageously, the photograph P capture substep E222 includes at least one determination substep E2221 of an orientation of the camera 37 of the mobile terminal 33, by means of the orientation detection device 38 and the controller 35 of the mobile terminal 33.

[0283] Here, the determination substep E2221 allows determining an orientation of the camera 37 of the mobile terminal 33 with respect to a frame R and, possibly, an inclination of the camera 37 of the mobile terminal 33 with respect to the ground and / or a plating 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 frame.

[0284] Advantageously, the third determination step E220 further includes a first sub-determination step E223 of at least one sky area C from the photograph P taken, during the capture sub-step E222, by means of the controller 35 of the mobile terminal 33.

[0285] Advantageously, the first substep of determination E223 includes image processing.

[0286] Advantageously, image processing, during the first determination substep E223, is implemented by the controller 35 of the mobile terminal 33, in particular by means of software embedded by the controller 35 of the mobile terminal 33.

[0287] Advantageously, the image processing, during the first substep of determination E223, consists of performing a binary segmentation of the photograph P to separate the sky C from the other elements of the photograph P, as illustrated in [Fig.5].

[0288] In one embodiment, such binary segmentation of the photograph P consists of evaluating a radiometry, in particular of the RGB (Red Green Blue) type, of the pixels of the photograph P, so as to determine a brightness of each pixel of the photograph P, and to determine brightness gradients for each column of the photograph P. When the gradient of brightness is high and, in particular, above a predetermined threshold, this can correspond to a boundary between the sky C and another element of the photograph P.

[0289] Advantageously, the photograph taken P, during the substep of taking E222, 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 and all other pixels are converted into black pixels.

[0290] Advantageously, the third determination step E220 includes a second sub-step E224 of the date and time determination during the taking sub-step E222.

[0291] Here, the second sub-step of determination E224 is implemented by means of the controller 35 of the mobile terminal 33.

[0292] Alternatively or in addition, the second determination substep E224 is implemented through the selection elements 14 and display 34 of the mobile terminal 33 and / or data transmitted by the server 28 to the second communication module 36 of the mobile terminal 33.

[0293] Advantageously, the third determination step E220 further comprises, in particular following the first determination substep E223 and, possibly, the second determination substep E224, a projection substep E225 of data from the photograph taken P, during the taking substep E222, into a projection frame V.

[0294] Here, the E225 projection substep is implemented by means of the controller 35 of the mobile terminal 33.

[0295] An example of the result of the projection of the data from the photograph P into the projection frame V is illustrated in [Fig.6].

[0296] The projection substep E225 is implemented based on orientation data from the camera 37 of the mobile terminal 33, determined during the determination substep E2221, which may be angles defining, in particular, a precession, i.e. pitch, a nutation, i.e. roll, and a proper rotation, i.e. yaw. Such angles are commonly called Euler angles.

[0297] Here, the projection substep E225 corresponds to a change of reference frame step 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 centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33 to the projection reference frame V.

[0298] Advantageously, the projection frame V is a frame in which angular coordinates of azimuth and elevation are represented. In [Fig. 7], the azimuth is represented on the x-axis and the elevation is represented on the y-axis, in an orthogonal Cartesian coordinate system.

[0299] Advantageously, the projection frame V of the photograph taken P, during the sub-step of taking E222, is a spherical celestial vault frame.

[0300] The angles, known as Euler angles, allow the orientation of an element, in particular of the camera 37 of the mobile terminal 33, to be expressed in spherical coordinates, in particular in the projection frame V, with respect to a Cartesian frame, in other words a three-dimensional frame, in particular the frame R, which can also be called the cardinal frame.

[0301] Here, for each direction from the location of the photovoltaic panel 25 relative to the shading installation 100, in the projection frame V, an azimuth angle is assimilated to a proper rotation angle in the frame R and an elevation angle is assimilated to a precession angle in the frame R.

[0302] Advantageously, the projection substep E225 of the data from the photograph taken P, during the taking substep E222, is further implemented as a function of a focal length of a lens of the camera 37 of the mobile terminal 33.

[0303] Advantageously, the projection substep E225 of the data from the photograph taken P, during the taking substep E222, is further implemented according to the dimensions of an image sensor of the camera 37 of the mobile terminal 33, in other words the horizontal and vertical field angles of the camera 37 of the mobile terminal 33.

[0304] In one embodiment, the projection substep E225, in the projection frame V, comprises a first substep 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 the focal point of the lens of the camera 37 of the mobile terminal 33. This first substep of the projection substep E225 requires prior input substep and a storage substep by the controller 35 of the mobile terminal 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 substep of the E225 projection substep thus yields a result comprising three matrices, each expressing a coordinate of each pixel of the photograph P along the X, Y, and Z axes of the second three-dimensional coordinate system. Furthermore, the E225 projection substep, in the projection coordinate system V, includes a second substep that transforms the result of the first substep of the E225 projection substep from the second three-dimensional coordinate system into the projection coordinate system. V is centered on the focal point of the camera lens 37 of the mobile terminal 33. This second substep of the projection substep E225 requires prior determination of each angle, known as the Euler angle, during the determination substep E2221, and application, using the controller 35 of the mobile terminal 33, of rotation matrices, known as Euler angles, for each of these angles. This second substep of the projection substep E225 thus yields 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 frame V.

[0305] Advantageously, the projection substep E225 is implemented according to the determined orientation of the camera 37 of the mobile terminal 33, during the determination substep E2221, 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, known as the Euler angle, determined during the determination substep E2221. The at least one of the angles, known as the 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 the angles, known as the Euler angles.

[0306] Advantageously, the third determination step E220 further comprises, in particular following the projection substep E225, a superposition substep E226 of data from the photograph taken P, during the taking substep E222, in particular from the projected photograph Pp, during the projection substep E225, onto a solar path diagram D, in the frame R, in particular in the projection frame V.

[0307] Here, the solar path diagram D is determined in the projection frame V.

[0308] The solar path diagram D, also called the solar diagram, is a diagram indicating, at different times of the year, the angular height, also called the angle height or elevation, of the sun and an azimuth of the sun's direction for a given latitude. The solar path diagram D thus makes it possible to define a path of the sun as perceived at the location of the photovoltaic panel 25 relative to the shading installation 100 for different times during the year. In this way, the solar path diagram D makes it possible to define times when direct incident solar radiation exists at the location of the photovoltaic panel 25 relative to the shading installation 100, particularly under weather conditions where the sky C is clear and in the absence of obstacles to solar radiation.

[0309] The solar path diagram D illustrated in [Fig. 7] is an example of a graphical representation for a given latitude and longitude. Each curve represents the apparent path of the sun as a function of time for a given date of the year.

[0310] Here, the E226 overlay substep is implemented by means of the controller 35 of the mobile terminal 33.

[0311] The superposition of the data of the photograph P taken, during the sub-step of taking E222, in particular of the projected photograph Pp, during the sub-step of projection E225, on the solar path diagram D, in the frame R, in particular in the projection 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 photovoltaic panel 25 with respect to the shading installation 100.

[0312] In order to implement the superposition substep E226, the data of the photograph P, in particular of the projected photograph Pp, and the data of the solar path diagram D are expressed in the same frame, in other words in a common frame.

[0313] The common frame can be, in particular, a cardinal frame, a three-dimensional frame centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33, a three-dimensional frame centered on the focal point of the lens of the camera 37 of the mobile terminal 33 or a spherical celestial vault frame, also called a projection frame.

[0314] Here, the superposition substep E226 is implemented from data of the projected photograph Pp, during the projection substep E225, on the solar path diagram D. Here, the data of the projected photograph Pp are obtained from the data of the photograph P taken, during the taking substep E222.

[0315] An example of the result of superimposing the data from the projected photograph Pp onto the solar path diagram D is illustrated in [Fig.7].

[0316] Advantageously, the third determination step E220 includes a data storage substep E227 defining the photograph taken P, during the taking substep E222, and, optionally, the projected photograph Pp, during the projection substep E225, in a memory of the controller 35 of the mobile terminal 33.

[0317] Here, the projection and superposition substeps E225, E226 are illustrated by geometric operations. Advantageously, the projection and superposition substeps E225, E226 are carried out without displaying any illustration of these substeps. These substeps can be grouped into a single calculation substep for determining the solar mask M.

[0318] The calculation substeps of the third determination step E220 have been described as being implemented locally in the mobile terminal 33. However, These calculation substeps can alternatively be implemented partially or fully in server 28.

[0319] In the preceding description, Figures 5 to 7 are an explanatory illustration of the digital processing performed. Additional or alternative digital processing may be implemented. The method of the invention may not at any time involve the display of the illustration, some of it, or a set of illustrations.

[0320] Advantageously, in the case where the battery 24 is not positioned opposite the photovoltaic panel 25, in other words the photovoltaic panel 25 is offset relative to the battery 24, by means of a vertical offset and / or a lateral offset relative to the opening 1 of the wall W of the building B, parallel to the plane along which the wall W extends, the method further comprises a step E350 of determining a solar shading, not shown, by means of the controller 35 of the mobile terminal 33, for a location of the battery 24 relative to the opening 1 of the wall W of the building B, hereafter referred to as the fifteenth determination step E350. The solar shading for the location of the battery 24 can be called the second solar shading.

[0321] The fifteenth determination step E350 is implemented in a similar manner to the third determination step E220 and includes, in particular, the same substeps E221 to E227 of the third determination step E220, for the location of the battery 24 instead of the location of the photovoltaic panel 25.

[0322] The offset of the photovoltaic panel 25 from the battery 24 along the wall W of the building B, according to the height and / or the width of the wall W, may be necessary, in particular, in the case where the window 40 is located under a balcony of the building B or in a loggia of the building B, or in the case where the window 40 is located opposite a significant obstacle to solar radiation, such as, for example, a tree or another building.

[0323] Thus, the incident illumination of the sun on the photovoltaic panel 25 is different from that on the battery 24, in particular on the box 9 or on the housing containing the battery 24.

[0324] Advantageously, the process further includes a determination step E240, in other words, a calculation step, of a value of a global inclined irradiance level, hereafter referred to as the sixth determination step E240. The inclined irradiance level corresponds to the total radiation received on a surface whose inclination and azimuth are defined.

[0325] Advantageously, the sixth determination step E240 is implemented starting from at least the value of the overall horizontal irradiance level determined during the fifth determination step E200, the orientation and, more particularly, the azimuth of wall W of building B determined during the second step of determination E210, the first solar mask M determined, during the third determination step E220, and, possibly, the second solar mask determined, during the fifteenth determination step E350.

[0326] Advantageously, the process further includes a determination step E250, in other words a calculation step, of a current value delivered by the photovoltaic panel 25, hereafter referred to as the seventh determination step E250.

[0327] Advantageously, the seventh determination step E250 is implemented from at least the value of the global inclined irradiance level determined, during the sixth determination step E240, an ambient temperature value read, during the reading step E190, a value of a voltage supplied by the selected battery 24, during the sixth selection step El60, and a value of at least one parameter of the selected photovoltaic panel 25, during the fifth selection step El50.

[0328] The or one of the parameters of the photovoltaic panel 25 is an electrical characteristic of the photovoltaic panel 25 and can be, for example, a short-circuit current, a current at the maximum power point, an open-circuit voltage or a voltage at the maximum power point of the photovoltaic panel 25.

[0329] The seventh determination step E250 corresponds to a modelling step of the photovoltaic panel 25.

[0330] Advantageously, the value of the voltage supplied by the battery 24 corresponds to that which is available at the terminals of the battery 14 when the latter is electrically disconnected from a load to be supplied with electrical energy, in particular from the electromechanical actuator 11. In other words, it is the open circuit voltage Vco, also called no-load voltage, of the battery 24.

[0331] Advantageously, the process includes a determination step E320, in other words a recovery step, of a value of energy consumed in standby by the motorized drive device 5, hereafter referred to as the thirteenth determination step E320.

[0332] Advantageously, the thirteenth determination step E320 is implemented from at least the electromechanical actuator 11 selected, during the fourth selection step El40.

[0333] In one embodiment, the standby energy consumption value of the motorized drive device 5 is determined, during the thirteenth determination step E320, by reading a table comprising at least as input data the electromechanical actuator 11 selected during the fourth selection step El40. Here, the table reading is implemented by means of the mobile terminal 33.

[0334] Advantageously, the process includes a determination step E330, in other words a calculation step, of a value of energy consumed by the motorized drive device 5 during a movement of the screen 2 of the occulting device 3, hereafter referred to as the fourteenth determination step E330.

[0335] Advantageously, the fourteenth determination step E330 is implemented from at least the electromechanical actuator 11 selected, during the fourth selection step El40, the battery 24 selected, during the sixth selection step El60, and the current consumption profile determined, during the fourth determination step El70.

[0336] In one embodiment, the energy value consumed by the motorized drive device 5 during a movement of the screen 2 of the occulting device 3 is determined, during the fourteenth determination step E330, by reading a table comprising at least as input data the electromechanical actuator 11 selected, during the fourth selection step E140, and the battery 24 selected, during the sixth selection step E160. Here, the reading of the table is implemented by means of the mobile terminal 33.

[0337] Advantageously, the energy consumed by the motorized drive unit 5 during a movement of the screen 2 of the shading device 3 is determined, in the fourteenth determination step E330, by multiplying the current consumption profile determined in the fourth determination step El70 by a voltage value supplied by the battery 24 selected in the sixth selection step El60, so as to obtain a power consumption profile. By integrating this power consumption profile over a time period corresponding to that of a movement of the screen 2 of the shading device 3, the energy consumed by the motorized drive unit 5 during a movement of the screen 2 of the shading device 3 is determined, in the fourteenth determination step E330.

[0338] Advantageously, the value of the voltage supplied by the battery 24 corresponds to that which is available at the terminals of the battery 14 when the latter is electrically connected to a load to be supplied with electrical energy, in particular the electromechanical actuator 11. In other words, it is the average voltage delivered by the battery 24.

[0339] Advantageously, the fourteenth determination step E330 is implemented, in addition, from a value of one or more parameters of the selected battery 24, during the sixth selection step El60.

[0340] In one embodiment, the value of the or each parameter of battery 24 is determined by reading a table comprising at least as input data Battery 24 was selected during the sixth selection step El60. Here, the table reading is implemented using the mobile terminal 33.

[0341] Advantageously, the method further comprises a selection step E360 of a use value of the motorized drive device 5, hereafter referred to as the seventh selection step E360.

[0342] The usage value corresponds to a number of movements performed by the motorized drive device 5 during a predetermined period of time, which may be, for example, a day.

[0343] Advantageously, the seventh selection step E360 of the use value of the motorized drive device 5 is implemented, in particular, by a choice from a list of values ​​or by an entry, in other words an input, of a value.

[0344] Advantageously, the method further includes a ninth substep of recording E361 the usage value of the motorized drive device 5 selected in a memory of the controller 35 of the mobile terminal 33.

[0345] Advantageously, the seventh selection step E360 is implemented, in addition, from the value of one or more parameters of the selected battery 24, during the sixth selection step El60.

[0346] In one embodiment, the value of the parameter or each parameter of the battery 24 is determined by reading a table including at least the selected battery 24 as input data, during the sixth selection step El60. Here, the table reading is implemented using the mobile terminal 33.

[0347] The method further includes a determination step E260, in other words a calculation step, of a value of a state of charge of the battery 24, hereafter referred to as the eighth determination step E260.

[0348] Advantageously, the eighth determination step E260 is implemented from at least the current value delivered by the photovoltaic panel 25 determined, during the seventh determination step E250, the energy value consumed in standby by the motorized drive device 5 determined, during the thirteenth determination step E320, the energy value consumed by the motorized drive device 5 during a movement of the screen 2 of the shading device 3 determined, during the fourteenth determination step E330, and the usage value of the motorized drive device 5 selected, during the seventh selection step E360.

[0349] The eighth determination step E260 corresponds to an energy modeling step of the motorized drive device 5.

[0350] The method further comprises at least one determination step E270, in other words a calculation step, of a temperature value which is representative of a temperature experienced by battery 24, subsequently called the ninth determination stage E270.

[0351] Advantageously, the ninth determination step E270 is implemented from at least the value of the global inclined irradiance level determined, during the sixth determination step E240, the value of the ambient temperature read, during the reading step E190, and, optionally, a value of at least one parameter related to the chest 9 or the housing containing the battery 24.

[0352] In one embodiment, the temperature value determined during the ninth determination step E270 is calculated from a mathematical relationship where the temperature value determined during the ninth determination step E270 is proportional to the ambient temperature value read during the reading step E190.

[0353] Alternatively, the temperature value determined during the ninth determination step E270 is calculated from a thermodynamic model applied to the chest 9 or to the housing containing the battery 24.

[0354] Thus, the ninth determination step E270 allows the value of the temperature experienced by the battery 24 to be determined at each instant for the geographical location determined, during the first determination step E180, for the orientation and, more particularly, the azimuth determined, during the second determination step E210, for the value of the ambient temperature read, during the reading step E190, and for the first solar mask M determined, during the third determination step E220, or the second solar mask determined, during the fifteenth determination step E350, in the case where the battery 24 is not arranged opposite the photovoltaic panel 25.

[0355] The ninth determination step E270 corresponds to a step of modelling the temperature value representative of the temperature undergone by the battery 24.

[0356] Advantageously, the method further includes a selection step E280 of a value of at least one parameter related to the chest 9 or the housing containing the battery 24, hereafter referred to as the eighth selection step E280.

[0357] The parameter or one of the parameters relating to the box 9 or the housing containing the battery 24 may be, for example, a colour, a material, a thermal characteristic of the box 9 or the housing, in particular in the case where the box 9 or the housing is visible from outside the building B, or even a method of installing the box 9 or the housing.

[0358] By way of non-limiting example, the method of installation of the box 9 or the casing may be a method of installation against an external face of the wall W of the building B or a method of installation under a lintel of the opening 1 made in the wall W of the building B.

[0359] Advantageously, the eighth selection step E280 of the value of the parameter related to the trunk 9 or the housing containing the battery 24 is implemented, in particular, by a choice from a list of values ​​of the parameter linked to the safe 9 or the box or by an entry, in other words an input, of an identifier of the value of the parameter linked to the safe 9 or the box.

[0360] Advantageously, the method further includes a tenth substep of recording E281 the value of the parameter related to the chest 9 or the housing containing the battery 24 selected in a memory of the controller 35 of the mobile terminal 33.

[0361] Advantageously, at least one or each of the first, second, third, fourth, fifth, sixth, seventh and eighth selection steps E100, E10, E120, E140, E150, E160, E360, E280 is implemented through the selection elements 14 and display 34 of the mobile terminal 33 or by reading an optical label, such as, for example, a barcode or a QR code (acronym for the Anglo-Saxon term "Quick Response"), by means of the camera 37 of the mobile terminal 33, or by receiving a radio tag, by means of the second communication module 36 of the mobile terminal 33, such as, for example, an RFID (acronym for the Anglo-Saxon term "Radio Frequency Identification") or NFC (acronym for the Anglo-Saxon term "Near Field Communication") tag.

[0362] Advantageously, each list is stored in a memory of the controller 35 of the mobile terminal 33 or in a memory of the server 28 configured to communicate with the mobile terminal 33.

[0363] Advantageously, the data retrieved during the first, second, third, fourth, fifth, sixth, seventh and eighth selection steps E100, E10, E120, E140, E150, E160, E360, E280 and during the first, second, third, thirteenth and fifteenth determination steps E180, E210, E220, E320, E350 are input data of the process, in other words constants.

[0364] Advantageously, the value of the torque profile developed, during the development step El30, the value of the current profile consumed determined, during the fourth determination step E170, and the value of energy consumed by the motorized drive device 5 determined, during the fourteenth determination step E330, are calculated only once during the execution of the process.

[0365] The method further includes at least one determination step E290, in other words a calculation step, of a value of a battery aging state 24, hereafter referred to as the tenth determination step E290.

[0366] The tenth determination step E290 is implemented from the temperature value determined during the ninth determination step E270, and, more particularly, by carrying out an integration operation of the latter over a predetermined period of time.

[0367] In other words, the tenth determination step E290 includes a calculation substep from a set of temperature values ​​determined, during the ninth determination step E270, over a predetermined period of time.

[0368] The tenth determination step E290 corresponds to a step of modelling the aging state of battery 24.

[0369] In other words, the tenth determination step E290 is a determination step of the value of the cumulative aging state of the battery 24 over time as a function of the temperature experienced by the battery 24.

[0370] The aging state of the battery 24 corresponds to an indicator of the degradation of the performance of the battery 24 over time, in particular in relation to a temperature value experienced by the battery 24 during each period of time of the predetermined time period.

[0371] The method further includes at least one determination step E300, in other words a calculation step, of a voltage profile delivered by the battery 24 during a movement of the screen 2 of the occulting device 3, hereafter referred to as the eleventh determination step E300.

[0372] The eleventh determination step E300 is implemented from at least the current consumption profile determined during the fourth determination step E170, the value of one or more parameters of the selected battery 24 during the sixth selection step E160, the value of the state of charge of the battery 24 determined during the eighth determination step E260, the temperature value determined during the ninth determination step E270, and the value of the state of aging of the battery 24 determined during the tenth determination step E290.

[0373] The eleventh determination step E300 corresponds to a dynamic battery modeling step 24.

[0374] In one embodiment, the value of the parameter or each parameter of the battery 24 is determined by reading a table including at least the selected battery 24 as input data, during the sixth selection step El60. Here, the table reading is implemented using the mobile terminal 33.

[0375] Advantageously, the voltage profile delivered by the battery 24 during a movement of the screen 2 of the occulting device 3 is defined by the open circuit voltage Vco of the battery 24 from which is subtracted the product of an internal resistance of the battery 24 and the current profile consumed during a movement of the screen 2 of the occulting device 3 determined, during the fourth determination step El70.

[0376] The method further includes at least one determination step E310, in other words a calculation step, of the operating state of the motorized drive device 5, hereafter referred to as the twelfth determination step E310.

[0377] The twelfth determination step E310 is implemented from at least the voltage profile delivered by the battery 24 determined, during the eleventh determination step E300, and a cut-off voltage value of the motorized drive device 5.

[0378] Advantageously, the twelfth determination step E310 includes at least one sub-step of comparison E311 of the voltage profile delivered by the battery 24 determined, during the eleventh determination step E300, to a predetermined threshold value of the cut-off voltage of the motorized drive device 5.

[0379] The predetermined cutoff voltage threshold value of the motorized drive device 5 corresponds to a low battery value.

[0380] The predetermined threshold value of the cut-off voltage of the motorized drive device 5 can be defined, in particular, either by a limit operating voltage value of the electronic control unit 15, in particular through its components or by a voltage value to be supplied at the start of the electric motor 16, or by a software operating value of the electronic control unit 15, to prevent a malfunction of the electromechanical actuator IL

[0381] In the event that the value of the voltage profile delivered by the battery 24 is strictly less than the predetermined low battery threshold value, a command to stop the electric motor 16 of the electromechanical actuator 11 would be issued by the electronic control unit 15.

[0382] The twelfth determination step E310 corresponds to a modeling step of the electromechanical actuator 11.

[0383] Thus, the method for determining the operating state of the motorized drive device 5 makes it possible to provide precise and simple information, in particular to installers and / or users, about the operating characteristics of the motorized drive device 5, in particular a determination, in other words an estimate, of an operating time of the battery 24, for defined installation conditions, such as at least the geographical location of the shading installation 100, the orientation of the wall W of the building B and the solar mask M for the location of the photovoltaic panel 25 in relation to the opening 1 of the wall W of the building B.

[0384] In this way, the information provided highlights the robustness of the characteristics of the motorized drive device 5, rather than providing information relating to the characteristics of the drive device motorized 5 corresponding to the worst use cases or the most advantageous use cases.

[0385] Here, the operating state of the motorized drive device 5 is the battery operating time 24.

[0386] Alternatively, the operating state of the motorized drive device 5 is the battery autonomy 24, regardless of the operating mode of the electromechanical actuator 11.

[0387] In another embodiment, the operating state of the motorized drive device 5 is a battery 24 autonomy for a predetermined operating mode of the electromechanical actuator 11. The operating mode of the electromechanical actuator 11 is preferably a nominal operating mode or, possibly, a degraded operating mode, such as, for example, an operating mode where the battery 24 has a state of charge value strictly below a predetermined threshold value. By way of non-limiting examples, in the degraded operating mode, the electric motor 16 drives the output shaft 20 at a reduced rotational speed compared to a nominal rotational speed, the electric motor 16 drives the output shaft 20 intermittently, or the electronic control unit 15 does not execute automatic control commands from, for example, the sensor 44 or the clock.

[0388] Advantageously, the sixth, seventh, eighth, ninth, tenth, eleventh, and twelfth determination steps E240, E250, E260, E270, E290, E300, E310 are implemented iteratively through a time loop, as illustrated in [Fig. 4]. The time loop is triggered from the first execution iteration of the sixth determination step E240 and is stopped when the result of the last execution iteration of the twelfth determination step E310 allows for the simulation of a failure of the motorized drive device 5. Each iteration of the time loop is implemented according to a predetermined periodicity.

[0389] Thus, the value of the overall inclined irradiance level determined during the sixth determination step E240, the value of the current delivered by the photovoltaic panel 25 determined during the seventh determination step E250, the value of the state of charge of the battery 24 determined during the eighth determination step E260, the temperature value representing the temperature experienced by the battery 24 determined during the ninth determination step E270, the value of the state of aging of the battery 24 determined during the tenth determination step E290, the value of the voltage profile delivered by the battery 24 determined during the eleventh determination step E300, and the operating state of the motorized drive device 5 determined during the twelfth determination step E310, are calculated respectively at each iteration of the time loop from the value of the previous iteration.

[0390] The predetermined periodicity of the time loop is dependent on the sampling period of the meteorological data read, during the reading step El90.

[0391] Advantageously, the method further includes a determination step E370, in other words a calculation step, of a value of the open circuit voltage Vco of the battery 24, following each iteration of the time loop, hereafter referred to as the sixteenth determination step E370.

[0392] Advantageously, the sixteenth determination step E370 is implemented from at least the value of the state of charge of the battery 24 determined, during the eighth determination step E260, the temperature value determined, during the ninth determination step E270, and the value of the state of aging of the battery 24 determined, during the tenth determination step E290.

[0393] Advantageously, the eighth determination step E260 of an ongoing iteration of the time loop is implemented, furthermore, from the value of the open circuit voltage Vco of the battery 24 determined, during the sixteenth determination step E370, from the previous iteration of the time loop, and from the value of the state of charge of the battery 24 determined, during the eighth determination step E260, from the previous iteration of the time loop.

[0394] Advantageously, the eighth determination step E260 is implemented, furthermore, from the value of the state of charge of the battery 24 determined, during the previous iteration of the eighth determination step E260, and from the value of the open circuit voltage Vco of the battery 24 determined, during the previous iteration of the sixteenth determination step E370.

[0395] Advantageously, each of the fourth to sixteenth determination steps E170, E200, E240, E250, E260, E270, E290, E300, E310, E320, E330, E350, E370 is implemented through the controller 35 of the mobile terminal 33.

[0396] Advantageously, the method further includes a display step E340 of the operating state of the motorized drive device 5 determined during the twelfth determination step E310.

[0397] Advantageously, the display step E340 is implemented through the display element(s) 34 of the mobile terminal 33.

[0398] Thanks to the present invention, the method for determining the operating state of the motorized drive device makes it possible to provide precise and simple information, particularly to installers and / or users, about the operating characteristics of the motorized drive device, in particular a determination, or rather an estimate, of the battery's operating time under certain conditions defined installation details, such as at least the geographical location of the shading installation, the orientation of the building wall and the solar mask for the location of the photovoltaic panel in relation to the opening in the building wall.

[0399] Numerous modifications can be made to the embodiment examples described above, without departing from the scope of the invention.

[0400] In an alternative, not shown, the electrical power supply device 26 further comprises a charger. The charger is configured to recharge the battery 24. The charger is configured to be electrically connected to the battery 24, either directly or via the electromechanical actuator 11 and / or the electronic control unit 15. The charger is configured to be plugged into a wall outlet so as to recharge the battery 24 from a mains power supply. This charger constitutes an external electrical power supply.

[0401] In an alternative, not shown, the electrical power supply device 26 further comprises an auxiliary battery, the auxiliary battery being configured to recharge, i.e., recharges, the battery 24. The auxiliary battery is configured to be electrically connected, i.e., is electrically connected, to the battery 24, either directly or via the electromechanical actuator 11 and / or the electronic control unit 15. Thus, the battery 24 can be recharged by means of the auxiliary battery, which forms an external power supply, particularly when the shading device 3 is located far from a wall outlet. Furthermore, the auxiliary battery can be used to recharge the battery of other electrical equipment, particularly portable devices, such as, for example, a mobile phone or a laptop computer.Furthermore, such an auxiliary battery can have at least two electrical outputs.

[0402] Alternatively, not shown, the electromechanical actuator 11 is inserted into a rail, particularly one with a square or rectangular cross-section, which can be open at one or both ends, particularly in the assembled configuration of the shading device 3. Furthermore, the electromechanical actuator 11 can be configured to drive a drive shaft around which cords for moving and / or tilting the screen 2 are wound. The screen 2 can advantageously be a slatted blind in this case. In this case, the shading device 3 comprises one or more movable bars, all of which can be moved by means of the electromechanical actuator 11.

[0403] Alternatively, not shown, the fourth, fifth and sixth selection steps E140, E150, E160 can be implemented through a single step grouping these steps together, instead of three separate steps. In this case, an assembly comprising an electromechanical actuator 11, a photovoltaic panel 25, and a battery 24 is selected. This assembly selection step is implemented, in particular, by choosing from a list of assemblies or by entering, in other words, inputting, an identifier for the assembly. Advantageously, the method includes a step of saving the selected assembly in a memory of the controller 35 of the mobile terminal 33.

[0404] Alternatively, and not shown, the overlay substep E226 can be implemented according to a different process. In such a case, the third determination step E220 comprises, prior to the overlay substep E226, a substep for determining the solar path diagram D in the spherical celestial vault frame. Then, the overlay substep E226 comprises a first substep for transferring data from the solar path diagram D from the spherical celestial vault frame to the three-dimensional frame centered on the focal point of the camera lens 37 of the mobile terminal 33, which can also be called the first three-dimensional frame.The overlay substep E226 includes a second substep for transferring the result of the first substep of the overlay substep E226 to the three-dimensional coordinate system centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33, which can also be called the second three-dimensional coordinate system. Furthermore, the overlay substep E226 includes a third substep for transferring the data from the photograph P taken during the capture substep E222 onto the previously determined solar path diagram D, in the three-dimensional coordinate system centered on a midpoint of the image sensor of the camera 37 of the mobile terminal 33, also called the common coordinate system and which can also be called the cardinal coordinate system.The second substep of the E226 overlay substep requires prior input substep and memorization substep by the controller 35 of the mobile terminal 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. In this case, the E226 overlay substep, in particular the first and second substeps of the E226 overlay substep, are implemented according to the focal length of a lens of the camera 37 of the mobile terminal 33 and / or the dimensions of the image sensor of the camera 37 of the mobile terminal 33.

[0405] Alternatively, not shown, in order to improve the determination of the sky area C, during the first determination substep E223, from the photograph taken P, during the capture substep E222, the capture substep E222 comprises a substep for optimizing at least one parameter of the image capture process for photograph P, and more specifically, for the camera 37 of the mobile terminal 33. The parameter(s) of image capture for photograph P could be, for example, the contrast or white balance of the image P. Advantageously, the optimization substep could include, for example, a first substep of capturing a test photograph and a second substep of determining at least one optimum parameter for capturing photograph P, based on the test photograph. Advantageously, the optimization substep is implemented following the positioning substep E221. Thus, the photograph P is taken, during the capture substep E222, by applying the optimum parameter(s) determined during the optimization substep.

[0406] In another variant, not shown, in order to improve the determination of the sky area C, during the first determination substep E223, from the photograph taken P, during the taking substep E222, the third determination step E220 may include a substep of positioning a cursor on the one or one of the display elements 34 of the mobile terminal 33, in particular a touch screen of the mobile terminal 33, at the level of a sky area C visible on the photograph P, by means of the one or one of the selection elements 14 of the mobile terminal 33.

[0407] Alternatively, not shown, the solar mask or each solar mask M determined during the third determination step E220 or the fifteenth determination step E350 can be implemented using data from server 28, which were obtained, in particular, from radar-type means to define a digital surface model, in other words a map, of a geographical area of ​​the Earth, in place of the photograph or each photograph P taken during the sub-taking step El22.

[0408] Furthermore, the envisaged embodiments and variants can be combined to generate new embodiments of the invention, without departing from the scope of the invention.

[0409] In [Fig.4] and in the description associated with this figure, the different stages of the The methods for determining the operating state of the motorized drive device 5 are presented in a specific order. This order is just one example, and many other sequences of steps ordered in different ways, defining as many variants, can be implemented. The only limitation is that some steps must be ordered chronologically when a second step uses the result of a first step.
