Title of the invention: Method for determining an operating state of a motorized drive device of a concealment device for a concealment installation

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

[0002] 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.

[0003] 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.

[0004] Document WO 2023 / 208949 A1 is already known, which describes a screening installation comprising a building, a window and a screening device. The building comprises a wall. The wall comprises an opening. The window is housed inside the opening of the wall. The screening device comprises a screen and a motorized drive device. The screen is configured to be arranged opposite the window, so as to partially or completely close the opening made in the wall. The motorized drive device comprises an electromechanical actuator, an electronic control unit and an electrical power supply device. The screen is configured to be driven in movement by the electromechanical actuator. 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 energy from the battery. The battery is supplied with electrical energy by means of the photovoltaic panel.

The method is implemented partly by means of a mobile terminal. The method comprises a step of selecting the electromechanical actuator, a step of selecting the photovoltaic panel, a step of selecting the battery, a step of determining a geographical location of the installation of occultation and a step of determining a solar mask, by means of a controller of the mobile terminal, for a location of the photovoltaic panel in relation to the opening of the wall of the building. This process is generally satisfactory.

[0006] However, this method of verifying the compatibility of the motorized drive device has the disadvantage of being silent with regard to determining an operating state of the motorized drive device and, more particularly, an autonomy of the battery, when the battery is not supplied with electrical energy by the photovoltaic panel due to zero or insufficient solar input.

[0007] Thus, this method does not make it possible to provide precise information in a simple manner about an operating state of the motorized drive device and, more particularly, about the battery life, 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 the document WO 2023 / 208949 A1, in particular a battery life value, in relation to worst-case use cases, for a range of motorized drive devices comprising respectively an electromechanical actuator, a battery and a photovoltaic panel.

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 lower than 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 rotation speed compared to a nominal rotation speed, the electric motor 16 drives the output shaft 20 in jerks or the electronic control unit 15 does not execute automatic control orders coming, for example, from the sensor 44 or the clock.

[0270] Advantageously, the fourth, fifth and sixth determination steps E200, E210, E220 are implemented iteratively through a time loop, as illustrated in [Fig.4]. The time loop is triggered from the first execution iteration of the fourth determination step E200 and is stopped when the result of the last execution iteration of the sixth determination step E220 makes it possible to simulate a failure of the drive device. motorized 5. Each iteration of the time loop is implemented according to a predetermined periodicity.

[0271] Thus, the value of the state of charge of the battery 24 determined, during the fourth determination step E200, the value of the voltage profile delivered by the battery 24 determined, during the fifth determination step E210, and the operating state of the motorized drive device 5 determined, during the sixth determination step E220, are calculated respectively at each iteration of the time loop from the value of the previous iteration.

[0272] The result of the sixth determination step E220 is independent of a periodicity of implementation of the iterations of the time loop. This periodicity can be a predetermined period of time of the order of several minutes, one or more hours or a day.

[0273] Advantageously, the number of iterations of the time loop implemented through the method according to the invention corresponds to a virtual cycling, which is representative of a cycling of the motorized drive device 5 which would be implemented in real operating conditions of the occultation device 3.

[0274] Advantageously, each iteration of the time loop is defined to correspond to the execution of a movement of the screen 2 of the occultation device 3, as defined previously.

[0275] Advantageously, the method further comprises a step E250 of determining, in other words calculating, a value of the open circuit voltage Vco of the battery 24, following each iteration of the time loop, subsequently called the seventh step of determining E250.

[0276] Advantageously, the seventh determination step E250 is implemented from at least the value of the state of charge of the battery 24 determined, during the fourth determination step E200.

[0277] Advantageously, the seventh determination step E250 is further implemented from a temperature value representative of a temperature experienced by the battery 24 and a value of an aging state of the battery 24.

[0278] Here, in order to simplify the calculation implemented during the seventh determination step E250, the temperature value is considered to be equal to a predetermined value, in other words to a constant, which may be, for example, twenty-five degrees Celsius, and the value of the aging state of the battery 24 is considered to be equal to a predetermined value, in other words to a constant, which may be, for example, that of a zero aging state corresponding to a new battery 24.

[0279] The aging state of the battery 24 corresponds to an indicator of degradation of the performance of the battery 24 over time, in particular in connection with a temperature value experienced by battery 24 during each time period of the time loop.

[0280] Advantageously, the fourth determination step E200 of a current iteration of the time loop is implemented, in addition, from the value of the open circuit voltage Vco of the battery 24 determined, during the seventh determination step E250, resulting from the previous iteration of the time loop, and from the value of the state of charge of the battery 24 determined, during the fourth determination step E200, resulting from the previous iteration of the time loop.

[0281] Advantageously, each of the first to seventh determination steps E170, E180, E190, E200, E210, E220, E250 is implemented through the controller 35 of the mobile terminal 33.

[0282] Advantageously, the method further comprises a step E230 of displaying the operating state of the motorized drive device 5 determined, during the sixth determination step E220.

[0283] Advantageously, the display step E230 is implemented through the display element(s) 34 of the mobile terminal 33.

[0284] Thanks to the present invention, the method for determining the operating state of the motorized drive device makes it possible to provide precise information in a simple manner, in particular to installers and / or users, about the operating characteristics of the motorized drive device, in particular a determination, in other words an estimation, of a battery life, when the battery is not supplied with electrical energy by the photovoltaic panel due to zero or insufficient solar input.

[0285] Numerous modifications can be made to the embodiments described above, without departing from the scope of the invention.

The charger is configured to recharge, in other words recharge, the battery 24. The charger is configured to be electrically connected, in other words is electrically connected, to the battery 24, either directly 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 into a wall outlet so as to recharge the battery 24 from a mains power supply. This charger forms an external electrical power supply source.

The auxiliary battery is configured to be electrically connected, in other words is electrically connected, to the battery 24, either directly 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, particularly portable equipment, such as, for example, a mobile phone or a laptop. Furthermore, such an auxiliary battery can have at least two electrical outputs.

[0290] 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 occulting 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. In this case, the occulting device 3 comprises a movable bar or a plurality of movable bars, which can all be moved by means of the electromechanical actuator 11.

[0291] As a variant, not shown, the fourth and sixth selection steps E140, E160 and, possibly, the fifth selection step E150 can be implemented through a single step grouping them together, instead of two or three separate steps. In this case, an assembly comprising an electromechanical actuator 11 and a battery 24 and, possibly, a photovoltaic panel 25 is selected. This step of selecting the assembly is implemented, in particular, by a choice from a list of assemblies or by an entry, in other words an input, of an identifier of the assembly. Advantageously, the method comprises a step of recording the selected assembly in a memory of the controller 35 of the mobile terminal 33.
