Description

Title of the invention: Method for controlling the operation of a motorized drive device, associated motorized drive device and occulting device

[0001] The present invention relates to a method for controlling the operation of a motorized drive device.

[0002] The present invention also relates to a motorized drive device adapted to implement this control method in operation, as well as a concealment device comprising such a motorized drive device.

[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 movable closing, concealing or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter called a screen.

[0005] Document WO 2012 / 059672 A2 is already known, which describes a method for controlling the operation of a motorized drive device. The motorized drive device comprises an electromechanical actuator, an electronic control unit, and an electrical power supply device. The electromechanical actuator comprises an electric motor. The electrical power supply device comprises a battery and a photovoltaic panel. The electronic control unit and the electric motor are supplied with electrical power from the battery. The battery is supplied with electrical power by means of the photovoltaic panel. The electronic control unit comprises a microcontroller and a measuring device. The measuring device is configured to measure a value of an open-circuit voltage supplied by the photovoltaic panel. The measuring device is electrically connected to the photovoltaic panel.The microcontroller comprises an input port for reading the value of the open-circuit voltage supplied by the photovoltaic panel and measured by the measuring device. In addition, the method comprises a step of measuring the value of the open-circuit voltage supplied by the photovoltaic panel.

[0006] However, this document WO 2012 / 059672 A2 is silent regarding the fact that the photovoltaic panel is part of a predetermined list of photovoltaic panel models, where the photovoltaic panel models respectively have different technical characteristics.

[0007] In the case of a screening installation, a plurality of screening devices are arranged on the same facade of a building. Each of the screening devices is equipped with a motorized drive device, which may be, for example, of the same type as that in document WO 2012 / 059672 A2.

[0008] In such a case, for reasons of aesthetic harmony, the user wishes the same model of photovoltaic panel to be installed on each of the occultation devices.

[0009] However, the screens of these occulting devices may have different dimensions and different weights.

[0010] Therefore, the motorized drive devices are also different, since the torque to be provided by the electromechanical actuator to move the screen of each of the occulting devices is different.

[0011] One possible approach would be to electrically connect the most powerful photovoltaic panel, from the predetermined list of photovoltaic panel models, with the battery and the electromechanical actuator of each of the motorized drive devices.

[0012] On the one hand, such an approach presents a problem in terms of accounting for the voltage delivered by the photovoltaic panel to the battery.

[0013] On the other hand, this approach presents a problem for the execution of functions by the electronic control unit, since these require that operating parameters stored by the electronic control unit are consistent between an electromechanical actuator model, a battery model and a photovoltaic panel model. In the case where the operating parameters stored by the electronic control unit are not consistent, in other words are not adapted, between the electromechanical actuator model, the battery model and the photovoltaic panel model, the functions are faulty, or even non-executable.

[0014] Therefore, to ensure the correct execution of the functions by the electronic control unit, it is imperative that the operating parameters stored by the electronic control unit are those associated with an electromechanical actuator model, a battery model and a photovoltaic panel model.

[0015] Another possible approach would be to inhibit the functions as soon as the operating parameters stored by the electronic control unit are not consistent between the electromechanical actuator model, the battery model and the photovoltaic panel model, so as to prevent the electronic control unit from executing these functions.

[0016] According to this second approach, the user would be deprived of the functions available for motorized drive devices where the photovoltaic panel model would not be suitable for the battery model and the electromechanical actuator model.

[0017] The present invention aims to resolve the aforementioned drawbacks and to propose a method for controlling the operation of a motorized drive device, a motorized drive device suitable for implementing this method of controlling the operation, as well as a concealment device comprising such a motorized drive device, making it possible to verify the operational compatibility of a photovoltaic panel model, from a predetermined list of photovoltaic panel models, with the other equipment of the motorized drive device.

[0018] In this regard, the present invention aims, according to a first aspect, at a method for controlling the operation of a motorized drive device,

[0019] the motorized drive device comprising at least:

[0020] - an electromechanical actuator,

[0021] - an electronic control unit, and

[0022] - an electrical energy supply device,

[0023] the electromechanical actuator comprising at least one electric motor,

[0024] the electrical energy supply device comprising at least:

[0025] - a battery, the electronic control unit and the electric motor being powered into electrical energy from the battery, and

[0026] - a photovoltaic panel, the battery being supplied with electrical energy at photovoltaic panel means,

[0027] the electronic control unit comprising at least:

[0028] - a microcontroller, and

[0029] - a measuring device, the measuring device being configured to measure at minus one value of an open-circuit voltage supplied by the photovoltaic panel, the measuring device being electrically connected to the photovoltaic panel, the microcontroller comprising at least one input port for reading the value of the open-circuit voltage supplied by the photovoltaic panel and measured by the measuring device,

[0030] the method comprising:

[0031] - a first step of measuring at least one value of the supplied open-circuit voltage by the photovoltaic panel.

[0032] According to the invention, the photovoltaic panel is part of a predetermined list of several models of photovoltaic panels.

[0033] Furthermore, the method further comprises at least:

[0034] - a comparison step, for each photovoltaic panel model, of the value of the no-load voltage measured, during the first measurement step, with at least one predetermined range of values ​​of the no-load voltage associated with the photovoltaic panel model, and

[0035] - an identification step, depending on the result of the comparison step, of the photovoltaic panel model from the predetermined list.

[0036] Thus, the method makes it possible to verify the operational compatibility of a photovoltaic panel model, from the predetermined list, with the other equipment of the motorized drive device.

[0037] In this way, the identification of the photovoltaic panel model, from the predetermined list, makes it possible to overcome potential problems in terms of compatibility of the voltage delivered by the photovoltaic panel to the battery.

[0038] Furthermore, the identification of the photovoltaic panel model, from the predetermined list, makes it possible to guarantee the correct execution of functions by the electronic control unit.

[0039] Furthermore, the identification of the photovoltaic panel model, from the predetermined list, is implemented by measuring at least one value of the open-circuit voltage supplied by the photovoltaic panel, since this physical quantity is relatively stable with respect to lighting conditions during a day and with respect to temperature conditions for each photovoltaic panel model.

[0040] Consequently, provided that the predetermined ranges of values ​​of the open-circuit voltage associated respectively with the models of photovoltaic panels are sufficiently spaced from each other, this measurement of at least one value of the open-circuit voltage supplied by the photovoltaic panel makes it possible to identify the model of photovoltaic panel from among the models of photovoltaic panels belonging to the predetermined list, whatever the value of the illumination level of the photovoltaic panel at the time of measurement of the value of the open-circuit voltage supplied by the photovoltaic panel.

[0041] According to an advantageous characteristic of the invention, for each photovoltaic panel model, the step of comparing the value of the measured open-circuit voltage, during the first measurement step, is implemented with a single predetermined range of values ​​of the open-circuit voltage associated with the photovoltaic panel model.

[0042] According to another advantageous characteristic of the invention, for each photovoltaic panel model, the step of comparing the value of the measured open-circuit voltage, during the first measurement step, is implemented with a plurality of predetermined ranges of values ​​of the open-circuit voltage associated with the photovoltaic panel model, each predetermined range of values ​​of the open-circuit voltage also being associated with a predetermined range of values ​​of an illumination level of the photovoltaic panel.

[0043] According to another advantageous characteristic of the invention, the or each predetermined range of values ​​of the open-circuit voltage associated with the photo panel model voltaic is defined for a temperature value representative of the temperature of the photovoltaic panel.

[0044] According to another advantageous characteristic of the invention, the method further comprises, following the identification step, a step of activating functions implemented by the electronic control unit and associated with the photovoltaic panel model identified, during the identification step.

[0045] According to another advantageous characteristic of the invention, the method is implemented during a commissioning phase of the motorized drive device.

[0046] According to another advantageous characteristic of the invention, the method is implemented periodically, either during a day of commissioning of the motorized drive device, or during the lifetime of the motorized drive device.

[0066] According to an advantageous characteristic of the invention, the occulting device further comprises a winding tube. The screen can be rolled onto the winding tube. Furthermore, the winding tube is arranged so as to be driven in rotation by the electromechanical actuator.

[0073] [Fig.6] [Fig.6] is a graph illustrating curves of the current as a function of the voltage for two models of photovoltaic panels and for different values ​​of illumination level of the two models of photovoltaic panels.

[0074] First of all, with reference to Figures 1 and 2, a screening installation 100 according to an embodiment of the invention is described. This screening installation 100 comprises at least one screening device 3. This screening installation 100, installed in a building, not shown, comprises at least one opening 1, in which a window 40 or a door is arranged, which is only shown in [Fig.l]. This occultation installation 100 is equipped with at least one screen 2 belonging to the occultation device 3, in particular a motorized roller shutter. The screen 2 of the occultation device 3 serves to more or less obscure the opening 1.

[0075] A closing installation and a sun protection installation are examples of occultation installations. Similarly, a closing device and a sun protection device are examples of occultation devices.

[0076] The closing, concealing or solar protection installation is subsequently called “concealing installation” 100.

[0077] The closing, concealing or sun protection device is subsequently called “concealing device” 3. The concealing device 3 comprises the screen 2.

[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.

[0079] A roller shutter conforming to the embodiment of the invention is described with reference to Figures 1 and 2.

[0080] The occulting device 3 comprises a motorized drive device 5. The motorized drive device 5 comprises an electromechanical actuator 11 illustrated in [Fig.3].

[0081] Advantageously, the occulting device 3 further comprises a winding tube 4. The screen 2 can be wound on the winding tube 4. Furthermore, the winding tube 4 is arranged so as to be driven in rotation by the electromechanical actuator 11.

[0082] Thus, the screen 2 of the occulting device 3 is wound onto the winding tube 4 or unwound around it, the winding tube 4 being driven by the motorized drive device 5, in particular by the electromechanical actuator 11.

[0083] In this way, the screen 2 is movable between a rolled-up position, in particular high, and an unrolled position, in particular low, and vice versa.

[0084] The screen 2 of the occultation device 3 is a closing, occultation and / or solar protection screen, winding and unwinding around the winding tube 4, the internal diameter of which is greater than the external diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, during the assembly of the occultation device 3.

[0085] The electromechanical actuator 11, in particular of the tubular type, makes it possible to rotate the winding tube 4 around an axis of rotation X, so as to move, in particular unwind or wind, the screen 2 of the occulting device 3.

[0086] In a mounted state of the occulting device 3, the electromechanical actuator 11 is inserted into the winding tube 4.

[0087] In a known manner, the roller shutter, which forms the concealment device 3, comprises an apron comprising horizontal slats articulated to each other, forming the screen 2 of the roller shutter 3, and guided by two lateral slides 6, shown only in [Fig.2]. These slats are joined when the apron 2 of the roller shutter 3 reaches its lower unrolled position.

[0088] In the case of a roller shutter, the upper rolled-up position corresponds to the support of a final end blade 8, for example L-shaped, of the apron 2 of the roller shutter 3 against an edge of a box 9 of the roller shutter 3 or to the stopping of the final end blade 8 in a programmed upper end-of-travel position. 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.

[0089] Here, the screen 2 is configured to be moved, by means of the motorized drive device 5, between an open position, corresponding to the rolled-up position and which can also be called the first end-of-travel position or the upper end-of-travel position FdCH, and a closed position, corresponding to the rolled-up position and which can also be called the second end-of-travel position or the lower end-of-travel position FdCB.

[0090] Thus, the electromechanical actuator 11 is configured to drive, in other words causes, the screen 2 to move between the first end-of-travel position FdCH and the second end-of-travel position FdCB, and vice versa.

[0091] The first slat of the roller shutter 3, opposite the final end slat 8, is connected to the winding tube 4 by means of at least one articulation 10, in particular a band-shaped attachment piece.

[0156] Advantageously, the torque support 21 of the electromechanical actuator 11 is configured to fix the electromechanical actuator 11 on a frame 23, in particular on a cheek of the trunk 9.

[0157] Thus, the torque support 21 makes it possible to take up the forces exerted by the electromechanical actuator 11, in particular the torque exerted by the electromechanical actuator 11, relative to the structure of the building. The torque support 21 advantageously makes it possible to take up, in addition, forces exerted by the winding tube 4, in particular the weight of the winding tube 4, of the electromechanical actuator 11 and of the screen 2, and to ensure the take-up of these forces by the structure of the building.

[0158] The torque support 21 is configured to be fixed, in other words is fixed, to the casing 17 by means of one or more fixing elements, in particular in the assembled configuration of the electromechanical actuator 11. The fixing element(s) may be, in particular, bosses, fixing screws, elastic snap-fastening fixing elements, ribs fitted into notches or a combination of these different fixing elements.

[0159] Furthermore, the torque support 21 of the electromechanical actuator 11 can support at least part of the electronic control unit 15.

[0160] Advantageously, the electronic control unit 15 can be supplied with electrical energy by means of an electrical power supply cable 18.

[0161] Here and as illustrated in [Fig.3], the electronic control unit 15 is thus arranged, in other words is integrated, inside the casing 17 of the electromechanical actuator 11.

[0162] As a variant, not shown, the electronic control unit 15 is arranged outside the casing 17 of the electromechanical actuator 11 and, in particular, mounted on the box 9 or in the torque support 21.

[0163] Advantageously, the torque support 21 can comprise at least one button, not shown.

[0164] This or these buttons can make it possible to adjust the electromechanical actuator 11 through one or more configuration modes, to pair one or more control units 12, 13 with the electromechanical actuator 11, to reset one or more parameters, such as, for example, an end-of-travel position, to reset the paired control unit(s) 12, 13 or even to command screen movement 2.

[0168] Advantageously, the output shaft 20 of the electromechanical actuator 11 is arranged inside the winding tube 4 and at least partly outside the casing 17 of the electromechanical actuator 11.

[0169] Here, one end of the output shaft 20 projects relative to the casing 17 of the electromechanical actuator 11, in particular relative to the second end 17b of the casing 17.

[0170] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive in rotation, in other words drives in rotation, a connecting element 22. This connecting element 22 is connected to the winding tube 4, in particular in the assembled configuration of the occulting device 3. The connecting element is, in the example of the figures, produced in the form of a wheel.

[0171] When the electromechanical actuator 11 is put into operation, the electric motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11 drives the winding tube 4 in rotation via the connecting element 22.

[0172] Thus, the winding tube 4 rotates the screen 2 of the occulting device 3, so as to open or close the opening 1.

[0175] The electrical energy supply device 26 is configured to supply, in other words supplies, electrical energy to the electromechanical actuator 11 and, more particularly, to the electronic control unit 15 and the electric motor 16.

[0176] Thus, the electrical power supply device 26 makes it possible to supply electrical power to the electromechanical actuator 11, without itself being electrically connected. strictly to a mains power supply network.

[0177] Here, the photovoltaic panel 25 is electrically connected to the battery 24, by an electrical connection L24-25.

[0178] The electromechanical actuator 11 is electrically connected to the electrical energy supply device 26 and, more particularly, to the battery 24, in particular by means of the electrical power supply cable 18.

Furthermore, the battery 24 is configured to be supplied, in other words is supplied, with electrical energy by the photovoltaic panel 25.

[0180] Thus, the recharging of the battery 24 is implemented by solar energy, by means of the photovoltaic panel 25.

[0181] Here and as illustrated in [Fig.2], the battery 24 is arranged outside the trunk 9.

[0189] The motorized drive device 5, in particular the photovoltaic panel 25 and / or the electronic control unit 15, comprises loading elements configured to charge the battery 24, from the solar energy recovered by the photovoltaic panel 25. In this case, the current flows between the components 25, 24 and 15 through a wired connection, which may be separate from the electrical power supply cable 18.

[0190] Thus, the charging elements configured to charge the battery 24, from solar energy, make it possible to convert the solar energy recovered by the photovoltaic panel 25 into electrical energy.

[0191] Alternatively or additionally, the motorized drive device 5, in particular the electromechanical actuator 11, is supplied with electrical energy from the battery 24, from an auxiliary battery, not shown, or from a mains electricity supply network, in particular from the commercial AC network, in particular depending on a state of charge of the battery 24.

The battery charging elements 24 may be arranged at the level of the second electronic card.

[0194] In the case where the electronic control unit 15 comprises a first electronic card and a second electronic card, not shown, the first electronic card of the electronic control unit 15 may be arranged inside the casing 17 of the electromechanical actuator 11. Furthermore, the second electronic card may be arranged inside the torque support 21 of the electromechanical actuator 11. Furthermore, the torque support 21 may comprise a cover, not shown. Furthermore, the second electronic card may be arranged inside a housing formed between a portion of the torque support 21 and the cover.

[0195] Advantageously, the photovoltaic panel 25 can be fixed on the box 9, on a wall of the building, on one of the side slides 6, on a pane of the window 40 or on a fixed frame of the window 40.

[0196] A part of an electrical diagram of the motorized drive device 5 illustrated in FIGS. 1 to 3, in accordance with an embodiment of the invention, is now described with reference to [Fig. 4].

[0197] The photovoltaic panel 25 is configured to provide, in other words provides or delivers, a voltage Vpv, which can also be called charging voltage.

[0198] The battery 24 is configured to provide, in other words supplies or delivers, a voltage Vbat.

[0199] The electronic control unit 15 further comprises a measuring device 33. The measuring device 33 is configured to measure, in other words measure, a physical quantity supplied by the photovoltaic panel 25. Here, the physical quantity measured is the no-load voltage Vco, also called “open circuit voltage”, supplied, in other words delivered, by the photovoltaic panel 25.

[0200] Thus, the electronic control unit 15 is configured to determine at least one value of the open-circuit voltage Vco of the photovoltaic panel 25 via the measuring device 33.

[0201] Advantageously, the measurement of the no-load voltage Vco is implemented, in particular, by means of a voltage divider bridge 33a. Advantageously, the measuring device 33 further comprises a switch 33b. The switch 33b may be, for example, a MOSFET type transistor (acronym for the English term “Metal Oxide Semi-conductor Field Effect Transistor”), which can be electronically controlled, in particular by the microcontroller 31 of the electronic control unit 15. The voltage divider bridge 33a and the switch 33b belong to the electronic control unit 15 and, more particularly, to the measuring device 33. Furthermore, a value of the measurement of the no-load voltage Vco is determined through an analog-digital converter 39 and the microcontroller 31 of the electronic control unit 15.

[0202] The measuring device 33 is electrically connected to the photovoltaic panel 25.

[0203] The microcontroller 31 comprises at least one input port 38 for reading the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 and measured by the measuring device 33. In other words, the input port 38 of the microcontroller 31 is configured to read the value of the voltage Vco supplied by the photovoltaic panel 25 and measured by the measuring device 33.

[0204] Advantageously, the input port 38 of the microcontroller 31 comprises the analog / digital converter 39. In this case, the analog / digital converter 39 is integrated into the microcontroller 31.

[0205] As a variant, not shown, the input port 38 of the microcontroller 31 is electrically connected to the analog / digital converter 39. In this case, the analog / digital converter 39 is a separate element from the microcontroller 31.

[0206] Advantageously, the electrical energy supply device 26 and, more particularly, the electronic control unit 15 further comprises a diode 48. The diode 48 is electrically connected, on the one hand, to the photovoltaic panel 25 and, on the other hand, to the battery 24.

[0207] Advantageously, the diode 48 is an integral part of the electrical connection L24-25 between the photovoltaic panel 25 and the battery 24.

[0208] Here, the diode 48 is arranged between the photovoltaic panel 25 and the battery 24. The diode 48 is said to be “passing” from the photovoltaic panel 25 to the battery 24 and said to be “blocking” from the battery 24 to the photovoltaic panel 25.

[0209] Here, the diode 48 makes it possible, in particular, to avoid a return of electrical energy from the battery 24 to the photovoltaic panel 25, when the value of the voltage Vpv supplied by the photovoltaic panel 25 is lower than a value of the voltage Vbat supplied by the battery 24.

[0210] In addition, the electronic control unit 15 is configured to measure, in other words measure, a charging current Ipv of the photovoltaic panel 25, in particular of one, several or all of the photovoltaic cells 43 of the photovoltaic panel 25. The measurement of the charging current Ipv is implemented by means of another measuring device, not shown, which may comprise, in particular, a shunt resistor, not shown. The shunt resistor belongs to the electronic control unit 15 and, more particularly, to the other measuring device. A value of the measurement of the charging current Ipv is determined through an analog-digital converter, not shown, and the microcontroller 31 of the electronic control unit 15.

[0211] In addition, the electronic control unit 15 is configured to measure, in other words measure, a short-circuit current Icc of the photovoltaic panel 25, in particular of one, several or all of the photovoltaic cells 43 of the photovoltaic panel 25. The measurement of the short-circuit current Icc is implemented by means of another measuring device, not shown, which may comprise, in particular, a shunt resistor, not shown. Advantageously, the other measuring device further comprises a switch, not shown. In one case, this switch may be the same as the switch 33b of the measuring device 33. Alternatively, this switch may be distinct from the switch 33b of the measuring device 33.The switch may be, for example, a MOSFET type transistor (acronym for the English term "Metal Oxide Semiconductor Field Effect Transistor"), which can be electronically controlled, in particular by the microcontroller 31 of the electronic control unit 15. The shunt resistor and the switch belong to the electronic control unit 15 and, more particularly, to the other measuring device. A value of the measurement of the short-circuit current Icc is determined at . through an analog-digital converter, not shown, and the microcontroller 31 of the electronic control unit 15.

[0212] In addition, the electronic control unit 15 is configured to measure, in other words measure, the charging voltage Vpv, in particular of one, several or all of the photovoltaic cells 43 of the photovoltaic panel 25. The measurement of the charging voltage Vpv is implemented by means of another measuring device, not shown, which may comprise, in particular, a voltage divider bridge, not shown. The voltage divider bridge belongs to the electronic control unit 15 and, more particularly, to the other measuring device. A value of the measurement of the charging voltage Vpv is determined through an analog-digital converter, not shown, and the microcontroller 31 of the electronic control unit 15.

[0213] Advantageously, the electronic control unit 15 further comprises a control unit 4L. Furthermore, the control unit 41 is electrically connected to the electric motor 16.

[0214] Thus, the control unit 41 is configured to supply electrical energy, in other words supplies electrical energy, to the electric motor 16.

[0215] Here, the battery 24 supplies the voltage Vbat to the control unit 4L

[0216] The photovoltaic panel 25 is part of a predetermined list of models 25 a, 25b, ..., 25n of photovoltaic panels 25. The predetermined list includes a plurality of models 25a, 25b, ..., 25n of photovoltaic panels 25.

[0217] The predetermined list of models 25a, 25b, ..., 25n of photovoltaic panels 25 may also be referred to as a range of models 25a, 25b, ..., 25n of photovoltaic panels 25. Further, each model 25a, 25b, ..., 25n of photovoltaic panel 25 may also be referred to as a reference 25a, 25b, ..., 25n of photovoltaic panel 25.

[0218] Advantageously, the predetermined list of models 25a, 25b, ..., 25n of photovoltaic panels 25 is stored in a memory, not shown, of the electronic control unit 15, in particular of the microcontroller 31.

[0219] Advantageously, the predetermined list of models 25a, 25b, ..., 25n of photovoltaic panels 25 can be updated during the lifetime of the motorized drive device 5.

[0220] Advantageously, the update is implemented by means of a configuration tool, which is configured to exchange, in other words exchange, data with the electronic control unit 15, either by wired communication or by wireless communication.

[0221] Advantageously, the configuration tool is a mobile terminal, which may be, for example, a smartphone, a tablet or a computer.

[0222] Alternatively or additionally, the configuration tool may be the local control unit 12 or the central control unit 13.

[0223] Here, the models 25a, 25b, ..., 25n of photovoltaic panels 25 belonging to the predetermined list respectively have different technical characteristics, for example, in terms of size and / or in terms of power delivered.

[0224] A method of executing a method for controlling the operation of the motorized drive device 5, illustrated in FIGS. 1 to 3, is now described with reference to FIGS. 5 and 6. This method of controlling the operation is in accordance with the invention.

[0225] The graph in [Fig.6] illustrates by different curves, for two different models 25a, 25b of photovoltaic panels 25 and for different illumination level values, the evolution of the current Ipv expressed in milliamperes (mA) as a function of the voltage Vpv expressed in volts (V).

[0226] As a non-limiting example, the graph was established for a first model 25a of photovoltaic panel 25 having a peak power of the order of 2.5 watts-peak (Wp in French or Wp in English) and a second model 25b of photovoltaic panel 25 having a peak power of the order of 5.8 watts-peak. In addition, the different curves of the graph were established for each of the two models 25a, 25b of photovoltaic panels 25 with an illumination level value of the photovoltaic panel 25 of between 100 W / m2 and 1000 W / m2.

[0227] A first rectangle shown in [Fig.6] makes it possible to visualize a range of values ​​of the open-circuit voltage Vco of the first model 25a of photovoltaic panel 25, in particular for a temperature of the order of 25°C. Furthermore, a second rectangle shown in [Fig.6] makes it possible to visualize a range of values ​​of the open-circuit voltage Vco of the second model 25b of photovoltaic panel 25, in particular for the same temperature of the order of 25°C.

[0228] The operating control method according to the invention comprises a first step E30 of measuring at least one value of the open-circuit voltage Vco supplied by the photovoltaic panel 25.

[0229] Advantageously, the first measurement step E30 is implemented by the measurement device 33 and by the electronic control unit 15 and, more particularly, by the microcontroller 31.

[0230] The method comprises a comparison step E50, for each model 25a, 25b, ..., 25n of photovoltaic panel 25, of the value of the open-circuit voltage Vco measured, during the first measurement step E30, with at least one predetermined range of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0231] Furthermore, the method comprises an identification step E100, depending on the result of comparison step E50, of model 25a, 25b, ..., 25n of photovoltaic panel 25 from the predetermined list.

[0232] Thus, the method makes it possible to verify the operating compatibility of a model 25a, 25b, ..., 25n of photovoltaic panel 25, from the predetermined list, with the other equipment of the motorized drive device 5, in particular with the electromechanical actuator 11, the electronic control unit 15 and the battery 24.

[0233] In this way, the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, among the predetermined list, makes it possible to overcome potential problems in terms of compatibility of the voltage Vpv delivered by the photovoltaic panel 25 to the battery 24.

[0234] Furthermore, the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, among the predetermined list, makes it possible to guarantee the correct execution of functions by the electronic control unit 15.

[0235] Furthermore, the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, from the predetermined list, is implemented by measuring at least one value of the open-circuit voltage Vco supplied by the photovoltaic panel 25, since this physical quantity is relatively stable with respect to lighting conditions during a day, in particular between the time of sunrise and the time of sunset, and with respect to temperature conditions for each model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0236] Consequently, provided that the predetermined ranges of values ​​of the open-circuit voltage Vco associated respectively with the models 25a, 25b, ..., 25n of photovoltaic panels 25 are sufficiently spaced from each other, this measurement of at least one value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 makes it possible to identify the model 25a, 25b, ..., 25n of photovoltaic panel 25 among the models 25a, 25b, ..., 25n of photovoltaic panels 25 belonging to the predetermined list, whatever the value of the illumination level of the photovoltaic panel 25 at the time of the measurement of the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25.

[0237] During a day, in particular between the time of sunrise and the time of sunset, the value of the open-circuit voltage Vco supplied by the measured photovoltaic panel 25 changes little, in other words changes within a limited range of values, depending on the level of illumination of the photovoltaic panel 25. This change in the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 depends on the characteristics thereof, in particular the type of photovoltaic cells 43 of the photovoltaic panel 25 and the number of the latter electrically connected in series. This small change in the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 during the day makes it possible to consider that this physical quantity is relatively stable. Thus, the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25 among the models 25a, 25b, ..., 25n of photovoltaic panels 25 belonging to the predetermined list is possible during a day, in particular between the time of sunrise and the time of sunset, independently of the level of illumination of the photovoltaic panel 25 at the time of measurement of the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25.

[0238] Furthermore, the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, from the predetermined list, using the method makes it possible to dispense with a mechanical keying device at the electrical connection L24-25 between the photovoltaic panel 25 and the battery 24.

[0239] Therefore, the cost of obtaining the motorized drive device 5 is lower.

[0240] Conversely, a measurement of at least one value of the charging current Ipv or the short-circuit current Icc supplied by the photovoltaic panel 25 does not make it possible to implement the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25 from the predetermined list, because the measurement of a value of the charging current Ipv or the short-circuit current Icc evolves linearly with the level of illumination of the photovoltaic panel 25 during a day, in particular between the time of sunrise and the time of sunset.

[0241] Thus, the value of the charging current Ipv or the short-circuit current Icc supplied by the photovoltaic panel 25 changes over the course of a day and depending on the weather conditions, which prevents the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25 from the predetermined list, unless the level of illumination of the photovoltaic panel 25 is precisely determined from an additional illumination sensor, which is independent of the photovoltaic panel 25.

[0242] Consequently, such a method of identifying the model 25a, 25b, ..., 25n of photovoltaic panel 25 from the predetermined list would be complex to implement and would require a relatively precise additional illumination sensor, generating a high cost of obtaining the motorized drive device 5.

[0243] Advantageously, the comparison step E50 and the identification step E100 are implemented by the electronic control unit 15 and, more particularly, by the microcontroller 31.

[0244] Advantageously, the or each range of values ​​of the open-circuit voltage Vco associated with each of the models 25a, 25b, ..., 25n of photovoltaic panels 25 is stored in a memory of the electronic control unit 15, in particular of the microcontroller 31.

[0245] Advantageously, the method further comprises, following the identification step E100, an activation step El 10 of functions implemented by the electronic control unit 15 and associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 identified, during the identification step E100.

[0246] Here, the functions implemented by the electronic control unit 15 may be, in particular, a control of the motorized drive device 5 as a function of the level of illumination, a performance diagnosis of the motorized drive device 5, or a diagnosis of installation or commissioning of the motorized drive device 5, this diagnosis being able to consist, in particular, of checking the electrical connection of the photovoltaic panel 25 to the battery 24, to the electronic control unit 15 and / or to the electromechanical actuator 11, or of checking that the photovoltaic panel 25 is not damaged, or even broken.

[0247] Advantageously, the activation step El 10 is implemented by the electronic control unit 15 and, more particularly, by the microcontroller 31.

[0248] In a first exemplary embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25, the comparison step E50 of the value of the no-load voltage Vco measured, during the first measurement step E30, is implemented with a single predetermined range of values ​​of the no-load voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0249] In the first exemplary embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25, prior to the comparison step E50, the method comprises a reading step E40 of a single predetermined range of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0250] In a second exemplary embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25, the comparison step E50 of the value of the no-load voltage Vco measured, during the first measurement step E30, is implemented with a plurality of predetermined ranges of values ​​of the no-load voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25. Each predetermined range of values ​​of the no-load voltage Vco is also associated with a predetermined range of values ​​of an illumination level of the photovoltaic panel 25.

[0251] Thus, the division of the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 as a function of the predetermined ranges of values ​​of the illumination level of the photovoltaic panel 25 makes it possible to avoid possible overlaps between the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the different models 25a, 25b, ..., 25n of photovoltaic panels 25 and, consequently, to avoid a possible impossibility of identifying the model 25a, 25b, ..., 25n of photovoltaic panel 25, during the identification step E100.

[0252] In the second exemplary embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25 and for each predetermined range of values ​​of the illumination level of the photovoltaic panel 25, the method comprises, prior to the comparison step E50, a reading step E40 of one of the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 and with the predetermined range of values ​​of the illumination level of the photovoltaic panel 25.

[0253] Advantageously, whether in the first or in the second embodiment, the reading step E40 is implemented by the electronic control unit 15 and, more particularly, by the microcontroller 31.

[0254] In the second exemplary embodiment, the determination of the illumination level of the photovoltaic panel 25 is implemented from an additional illumination sensor, not shown. In this case, the motorized drive device 5 comprises the additional illumination sensor.

[0255] Here, the determination of the illumination level of the photovoltaic panel 25 does not require high precision when this is associated with the measurement of values ​​of the open-circuit voltage Vco to implement the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25 from the predetermined list, compared to the case where the determination of the illumination level of the photovoltaic panel 25 is associated with the measurement of values ​​of the charging current Ipv or the short-circuit current Icc. The determination of the illumination level of the photovoltaic panel 25 can be implemented approximately to determine only an order of magnitude of the illumination level of the photovoltaic panel 25.

[0256] Advantageously, the additional illumination sensor is configured to implement, in other words implements, at least one measurement of one or more physical quantities linked to the illumination level, such as, for example, the charging current Ipv and / or the short-circuit current Icc.

[0257] Here, the additional illumination sensor is independent of the photovoltaic panel 25, that is to say that this illumination sensor is distinct from the photovoltaic cells 43 of the photovoltaic panel 25.

[0258] Advantageously, the additional illumination sensor is external to the photovoltaic panel 25. Furthermore, the additional illumination sensor is configured to be electrically connected, in other words is electrically connected, to the electronic control unit 15, so as to transmit at least one signal representative of the illumination level of the photovoltaic panel 25 as a function of the measurement(s) taken.

[0259] Alternatively, the additional illumination sensor is integrated into the photovoltaic panel 25. In this case, the additional illumination sensor is a photodiode or an additional photovoltaic cell independent of the photovoltaic cells 43 of the photovoltaic panel 25, in other words an additional photovoltaic cell not electrically connected to the photovoltaic cells 43 of the photovoltaic panel 25.

[0260] Alternatively, the additional illumination sensor is a virtual illumination sensor. The determination of the virtual illumination level is implemented by interrogating, in particular, the server 28. The virtual illumination sensor is a set of means for simulating a real illumination sensor and producing data that 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.

[0261] In another variant, the determination of the illumination level of the photovoltaic panel 25 can be implemented by a measurement of one or more other physical quantities linked to the illumination level of the photovoltaic panel 25, such as, for example, the charging current Ipv and / or the short-circuit current Icc. In this case, the motorized drive device 5 is devoid of an additional illumination sensor, in other words the photovoltaic panel 25 is used as an illumination sensor.

[0262] Furthermore, the determination of the illumination level of the photovoltaic panel 25 cannot be implemented from the value of the no-load voltage Vco measured, during the first measurement step E30, given that this measurement does not make it possible to determine the illumination level of the photovoltaic panel 25 in a sufficiently precise manner.

[0263] Nevertheless, the measurement of several values ​​of the open-circuit voltage Vco at different times makes it possible to determine a strong variation, in other words a significant change, in the level of illumination of the photovoltaic panel 25, which may correspond, for example, to the time of sunrise, to the time of sunset, or to the time of a change from a cloudless illumination condition to a cloudy illumination condition, or vice versa.

[0264] In this second exemplary embodiment, the method further comprises a second step E60 of measuring a value of the illumination level of the photovoltaic panel 25.

[0265] Advantageously, whatever the physical quantity used and whatever the means used to determine the level of illumination of the photovoltaic panel 25, the method further comprises:

[0266] - another comparison step E70 of the value of the illumination level of the photovoltaic panel 25 measured, either during the first measurement step E30, or during the second measurement step E60, with predetermined threshold values ​​Sla, S 1b,, Sln, the predetermined threshold values ​​Sla, Slb,, Sln corresponding to the limits of the predetermined value ranges of the illumination level of the photovoltaic panel 25, and

[0267] - in response to the other comparison step E70, a determination step E80 of one of the predetermined ranges of values ​​of the illumination level of the photovoltaic panel 25.

[0268] Advantageously, the second measurement step E60, the other comparison step E70 and the determination step E80 are implemented prior to the comparison step E50 and, more particularly, to the reading step E40.

[0269] Advantageously, the or each predetermined range of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 is defined for a temperature value representative of the temperature of the photovoltaic panel 25.

[0270] Thus, the or each predetermined range of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 and with the temperature value makes it possible to avoid possible overlaps between the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the different models 25a, 25b, ..., 25n of photovoltaic panels 25 and, consequently, to avoid a possible impossibility of identifying the model 25a, 25b, ..., 25n of photovoltaic panel 25, during the identification step E100.

[0271] In this way, taking into account the temperature value makes it possible to identify more reliably the predetermined value ranges of the open-circuit voltage Vco associated respectively with the models 25a, 25b, ..., 25n of photovoltaic panels 25, in particular when the difference between them is close.

[0272] Advantageously, the temperature value is measured. In this case, the method further comprises, prior to the comparison step E50 and, more particularly, to the reading step E40, a third step E90 of measuring the temperature.

[0273] Advantageously, the third measurement step E90 is implemented by a temperature sensor, not shown, and by the electronic control unit 15 and, more particularly, by the microcontroller 31.

[0274] Here, the temperature value is a temperature value of the photovoltaic panel 25 and, more particularly, of the photovoltaic cells 43 of the photovoltaic panel 25.

[0275] Alternatively, not shown, the temperature value is an ambient temperature value or a temperature value internal to the electromechanical actuator 11, such as, for example, that inside the casing 17 or that of the electric motor 16. In this case, the temperature value is corrected by taking into consideration at minus a value of the illumination level of the photovoltaic panel 25, which is measured either during the first measurement step E30, or during the second measurement step E60, as described previously.

[0276] In the first exemplary embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25 and for the temperature value, the reading step E40 is implemented taking into account one of the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 and the measured temperature value, during the third measurement step E90.

[0277] In the second embodiment, for each model 25a, 25b, ..., 25n of photovoltaic panel 25, for each predetermined range of values ​​of the illumination level of the photovoltaic panel 25 and for each temperature value, the reading step E40 is implemented taking into account one of the predetermined ranges of values ​​of the open-circuit voltage Vco associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25, the range of values ​​of the illumination level of the photovoltaic panel 25 determined, during the determination step E80, and the measured temperature value, during the third measurement step E90.

[0278] Advantageously, the method further comprises:

[0279] - prior to the first measurement step E30, an initial measurement step E10 of at least one value of the charging current Ipv of the battery 24 by the photovoltaic panel 25, and

[0280] - an initial comparison step E20 of the value of the charging current Ipv measured, during the initial measurement step E10, with a predetermined threshold value of current S0.

[0281] Advantageously, the predetermined threshold value of current S0 is a zero value of charging current Ipv.

[0282] Thus, in the case where the value of the charging current Ipv measured, during the initial measurement step E10, is strictly greater than the predetermined threshold value of current S0, a value of the voltage Vpv delivered by the photovoltaic panel 25 is positive.

[0283] Furthermore, in the case where the value of the charging current Ipv measured, during the initial measurement step E10, is strictly greater than the predetermined threshold value of current S0, a value of the voltage Vpv delivered by the photovoltaic panel 25 is strictly greater than a value of the voltage Vbat delivered by the battery 24.

[0284] In this case, the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 is representative of the operation of the photovoltaic panel 25 to supply electrical energy to the battery 24 during the day, in other words between the time of sunrise and the time of sunset.

[0285] Therefore, the following steps of the method can be implemented, in par particular from the first measurement step E30, in order to identify the model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0286] Otherwise, if the value of the charging current Ipv measured, during the initial measurement step E10, is less than or equal to the predetermined threshold value of current S0, the value of the voltage Vpv delivered by the photovoltaic panel 25 is less than or equal to the value of the voltage Vbat delivered by the battery 24.

[0287] In this case, the value of the open-circuit voltage Vco supplied by the photovoltaic panel 25 is not representative of the operation of the photovoltaic panel 25 to supply electrical energy to the battery 24 during the day, in other words between the time of sunrise and the time of sunset.

[0288] This case corresponds to a measurement of the illumination level of the photovoltaic panel 25 in low light conditions, which may be either at night or in a dark environment.

[0289] Consequently, the following steps of the method cannot be implemented, in particular from the first measurement step E30, in order to identify the model 25a, 25b, ..., 25n of photovoltaic panel 25, given that the values ​​of the open-circuit voltage Vco of the different models 25a, 25b, ..., 25n of photovoltaic panels 25 are close, or even identical, and, in particular, zero.

[0290] Advantageously, in the case where the physical quantity used to determine the level of illumination of the photovoltaic panel 25, during the determination step E80, is the charging current Ipv, the second measurement step E60 and the initial measurement step E10 can be grouped together in a single step of the method.

[0291] Advantageously, the method is implemented, in particular steps E10 to E110 of the method are implemented, during a phase of commissioning of the motorized drive device 5, in particular either during the electrical connection of the photovoltaic panel 25 to the battery 24, or during the electrical activation of the electromechanical actuator 11 electrically connected to the battery 24, itself electrically connected to the photovoltaic panel 25.

[0292] Thus, following the identification step E100, the activation step E110 is implemented, so that the electronic control unit 15 selects operating parameters associated with the model 25a, 25b, ..., 25n of photovoltaic panel 25 identified, during the identification step E100.

[0293] In this way, the electronic control unit 15 is configured to execute, in other words executes, functions by applying operating parameters adapted to the model 25a, 25b, ..., 25n of photovoltaic panel 25 which is electrically connected to the electromechanical actuator 11 and which is identified, during the identification step El00.

[0294] The functions performed by the electronic control unit 15 are, for example, parameterization and / or configuration functions of the electromagnetic actuator 11 linked to the model 25a, 25b, ..., 25n of photovoltaic panel 25.

[0295] Alternatively or additionally, the method is implemented, in particular steps E10 to E110 of the method are implemented, periodically, either during the day of commissioning of the motorized drive device 5, or during the lifetime of the motorized drive device 5. In this case, the method makes it possible to verify that the model 25a, 25b, ..., 25n of photovoltaic panel 25 initially installed, either has not been changed during the day of commissioning of the motorized drive device 5, or has not been changed during the lifetime of the motorized drive device 5.

[0296] Thanks to the present invention, the method makes it possible to verify the operational compatibility of a photovoltaic panel model, from the predetermined list, with the other equipment of the motorized drive device.

[0297] Numerous modifications can be made to the embodiments described above, without departing from the scope of the invention.

[0298] As a variant, not shown, the electrical energy supply device 26 further comprises a charger. The charger is configured to be electrically connected, in other words is electrically connected, to the battery 24, either directly to the latter, or through the electromechanical actuator 11 and / or the electronic control unit 15. The charger is configured to be plugged in, in other words is plugged in, to a wall electrical outlet, so as to recharge the battery 24 from a mains electricity supply network. This charger forms an external electrical energy supply source. In the case where the charger is electrically connected to the battery 24 instead of the photovoltaic panel 25, the method described previously allowing the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, from the predetermined list, cannot be implemented.

[0299] As a variant, not shown, the electrical power supply device 26 further comprises an auxiliary battery, the auxiliary battery being configured to recharge the battery 24. The auxiliary battery is configured to be electrically connected, in other words is electrically connected, to the battery 24, either directly to the latter, or through the electromechanical actuator 11 and / or the electronic control unit 15. Thus, the battery 24 can be recharged by means of the auxiliary battery forming an external electrical power supply source, in particular in the case where the occulting device 3 is far from a wall electrical outlet. In addition, the auxiliary battery can be used to recharge a battery of other electrical equipment, in particular portable equipment, such as, for example, a mobile phone or a laptop. Furthermore, such an auxiliary battery can have at least two electrical outputs, in particular a first output delivering a voltage of 12 volts to supply electrical energy to the battery 24 and a second output delivering a voltage of 5 volts to supply electrical energy to other electrical equipment, called nomadic. In the case where the auxiliary battery is electrically connected to the battery 24 instead of the photovoltaic panel 25, the method described previously allowing the identification of the model 25a, 25b, ..., 25n of photovoltaic panel 25, from the predetermined list, cannot be implemented.

[0300] As a variant, not shown, the electromechanical actuator 11 is inserted into a rail, in particular of square or rectangular section, which can be open at one or both of its ends, in particular in the assembled configuration of the occultation device 3. Furthermore, the electromechanical actuator 11 can be configured to drive a drive shaft on which cords for moving and / or orienting the screen 2 are wound, which can, advantageously, be a slatted blind in this case.

[0301] Furthermore, the embodiments and variations contemplated may be combined to generate new embodiments of the invention, without departing from the scope of the invention.
