Description

The present invention relates to a method for controlling the operation of a motorized drive device. The present invention also relates to a motorized drive device adapted to implement this control method in operation, as well as a blackout device comprising such a motorized drive device. 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. 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, hereafter referred to as a screen. We already know the document WO 2012/059672 A2 This method describes a control method for a motorized drive device. The motorized drive device includes an electromechanical actuator, an electronic control unit, and an electrical power supply. The electromechanical actuator includes an electric motor. The electrical power supply includes a battery and a photovoltaic panel. The electronic control unit and the electric motor are powered from the battery. The battery is powered by the photovoltaic panel. The electronic control unit includes a microcontroller and a measuring device. The measuring device is configured to measure the open-circuit voltage supplied by the photovoltaic panel. The measuring device is electrically connected to the photovoltaic panel. The microcontroller includes an input port for reading the open-circuit voltage supplied by the photovoltaic panel and measured by the measuring device. The method also includes a step for measuring the open-circuit voltage supplied by the photovoltaic panel. 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. In the case of a shading system, multiple shading devices are arranged on the same facade of a building. Each of the shading devices is equipped with a motorized drive device, which could be, for example, of the same type as that in the document WO 2012/059672 A2 . 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 shading devices. However, the screens of these blackout devices can have different dimensions and weights. Therefore, the motorized drive devices are also different, since the torque to be supplied by the electromechanical actuator to move the screen of each of the blackout devices is different. 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 electromechanical actuator of each of the motorized drive devices. On the one hand, such an approach presents a problem in terms of compatibility of the voltage delivered by the photovoltaic panel to the battery. On the other hand, this approach presents a problem for the execution of functions by the electronic control unit, since these functions require that the operating parameters stored by the electronic control unit be consistent between an electromechanical actuator model, a battery model, and a photovoltaic panel model. If the operating parameters stored by the electronic control unit are not consistent, in other words, are not appropriate, between the electromechanical actuator model, the battery model, and the photovoltaic panel model, the functions will fail or even be impossible to execute. Therefore, to ensure the correct execution of 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. 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. 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 adapted to the battery model and the electromechanical actuator model. The present invention aims to resolve the aforementioned drawbacks and to propose a method for controlling a motorized drive device in operation, a motorized drive device adapted to implement this control method in operation, and a shading device comprising such a motorized drive device, allowing verification of the operational compatibility of a photovoltaic panel model, from a predetermined list of photovoltaic panel models, with the other equipment of the motoriz
