Description

The present invention relates to a control method in operation of a screening or solar protection installation.

The present invention also relates to an installation suitable for implementing this control method.

In general, the present invention relates to the field of screening devices comprising a motorized drive device that sets a screen in motion between at least a first position and at least a second position.

A motorized drive device comprises an electromechanical actuator for a movable shading or solar protection element, such as a blind, a curtain or any other equivalent material, hereinafter called a screen.

We already know the document WO 2014/102221 A1 which describes a screening or solar protection installation comprising a screening device, arranged inside a building, and a window of the building. The concealment device comprises a screen, a motorized drive device and an independent electric power supply device. The screen is configured to deploy facing the window of the building. The motor drive device includes an electromechanical actuator and an electronic control unit. The electromechanical actuator is configured to move the screen between a first end-of-travel position and a second end-of-travel position. The electromechanical actuator is electrically connected to the autonomous electric power supply device. The autonomous electrical energy supply device comprises a photovoltaic module and an electrical energy storage device. The photovoltaic module is arranged at the level of the screen. The photovoltaic module is electrically connected to the electrical energy storage device. The photovoltaic module includes a photovoltaic panel. The electrical energy storage device includes a battery.

This installation is configured to implement an operating control method comprising a step of determining a first and a second battery charging position by means of the photovoltaic panel.

However, this method of controlling this installation in operation has the drawback that the photovoltaic panel may not be exposed to a sunlight coming from outside the building through the window at least at certain times of the day, in particular in the first and second end positions of the screen. In such a position of the screen, the photovoltaic panel can, in particular, be masked by a wall of the building.

In addition, this control method in operation of this installation also has the drawback that movements of the screen to one of the charging positions are implemented while the photovoltaic panel is not exposed to a sunlight, after reaching the charging position. In such a charging position, the photovoltaic panel can be hidden by a wall of the building or a solar mask located between the sun and the window of the building or even not sunny due to the course of the sun with respect to the geographical location of the installation and/or building window orientation.

Furthermore, in the absence of direct and incident sunlight on the photovoltaic panel, i.e. the photovoltaic panel is only exposed to indirect radiation, in other words diffuse and reflected, the solar energy recovered by the photovoltaic panel is relatively low.

Consequently, these movements of the screen to one of the charging positions generate electrical energy consumption for the battery, which may not be compensated by the solar energy recovered thanks to the exposure to the sun of the photovoltaic panel in the charging position reached, following the movement of the screen.

Furthermore, in the case where the screening device is arranged above the window and the user wishes to open a leaf of the window, in particular of the casement or tilt-and-turn type, the screen can be raised to the above the window and, more particularly, at a high limit position, so that the photovoltaic panel is not exposed to sunlight coming from outside the building. In such a position of the screen, the photovoltaic panel is hidden by a wall of the building.

The object of the present invention is to solve the aforementioned drawbacks and to propose a method for controlling a screening or solar protection installation in operation, as well as a screening or solar protection installation, making it possible to guarantee sunshine. of a photovoltaic panel arranged at the level of a screen of a screening device, when the screen is moved, by means of an electromechanical actuator, into one of the positions for recharging a battery by means of the photovoltaic panel, so as to avoid displacements of the screen to one of the charging positions causing electrical energy consumption for the battery, which may not be compensated by the solar energy recovered through exposure to the sun of the photovoltaic panel in the charging position reached, following the displacement of the screen.
