Embodiment Construction

[0019] The invention relates to an increase in the autonomy of self-powered roller shutters.

[0020] Such roller shutters comprise a drive with an electric motor, wherein the electric motor is connected to an autonomous power supply. The autonomous power supply also includes batteries. Preferably, the battery is designed to be rechargeable, in the form of an accumulator, such as a lithium battery or other. In addition, the device is connected to the battery to charge it, preferably by harvesting renewable energy, such as solar or wind energy, and then converting this energy into electrical current.

[0021] In this regard, such conversion and charging means are capable of charging the battery according to its charge level. Means for measuring this charge level can be provided. This means may involve, for example, sensors for measuring the voltage at the terminals of said battery in order to allow or not to charge it. The charge limit is determined in advance according to ...

Abstract

The invention relates to the recovery of the potential energy from the apron of a roller blind including driving means provided with a motor connected to autonomous supply means during the expansion or retraction phase of the apron. More particularly, during the expansion or retraction phase of the apron, the method comprises determining an energy recovery phase corresponding to a motor torque applied by the apron on the driving means. The invention also allows energy recovery without damaging the components of said blind.

Description

technical field [0001] The invention relates to the field of rolling shutters, in particular to the field of rolling shutters with autonomous power supply. Background technique [0002] Such roller shutters consist of a curtain formed by hinged panels, the side ends of which are internally slid along side rails by motorized means when the curtain is changed from an unrolled condition to a rolled condition about an axis ,vice versa. [0003] In the context of the invention, said motorization is autonomously powered by batteries. Furthermore, the battery can be designed to be rechargeable, in the form of an accumulator. Charging of the battery can take place in particular by means of renewable energy conversion sensors, such as photoelectric sensors for converting solar energy, wind sensors or others. [0004] The main difficulty of autonomously powered devices consists in optimizing their operating time while retaining high reliability. In the context of the roller shutte...
