Description

System for winding / development of awnings, blinds and curtains.

Object of the invention

The present invention relates to a system which has been specially designed to control the winding / development of awnings, blinds and curtains of automatically

The object of the invention is to provide a device that allows to regulate very precisely the positioning of the mentioned awnings, blinds and curtains.

It is also the object of the invention to provide a system by which the modification of the parameters of awning pickup / extension automatically can be easily varied, without having to access the electronics associated with the engine of winding / development.

Background of the invention

In the practical scope of the invention, that is, the winding / unwinding systems
Rolling awnings, blinds and curtains are known systems that by means of an electric motor allow regulating through the corresponding controls the positioning of said awnings or windows, incorporating said systems means light and wind detectors that allow automatically control the positioning of the said awnings, blinds and curtains before excessive wind or solar intensity, carrying out the winding or development of said elements depending on the specific case, without the need for the user to be aware of such climatic changes.

These types of devices have a problematic that focuses primarily on two aspects:

First of all it should be noted that the regulation positional of the aforementioned awnings, blinds and curtains is performed by controlling mechanical limit switches, which prevents a continuous positional regulation, said regulation being discrete positional, that is limited by the steps defined in the pinion teeth of the corresponding mechanism, which is translates into a regulation of the position of the awning or blind staggered, with amplitudes that although tend to be small, do not allow intermediate positions between these staggering

As for the means of automatic control of rise and fall of blinds or awnings in the face of excessive wind or a strong solar irradiation, it should be noted that they come factory preprogrammed, so if you want to vary these parameters, it is necessary to access the electronic control of the same, established next to the drive motor of the corresponding mechanism, with the consequent and difficult accessibility that this implies, due to the disposition that these elements occupy within the house in which they remain installed.

Description of the invention

The system for winding / development of awnings, blinds and curtains that the invention proposes resolves in a fully satisfactory manner the problematic previously exposed, allowing to carry out a millimeter adjustment of the positioning of said awnings and / or blinds, as well as incorporating a control knob through the that the automatic programming parameters can be modified of the system without having to access the electronics associated with the drive motor of the corresponding mechanisms.

For this, the system that is recommended is constituted from three independent elements, a module engine, a remote control module and a wind / sun sensor module, that communicate with each other through radio frequency signals, although as many motor modules as possible can be established necessary, all of them controlled by the control module remote.

More specifically, the engine module incorporates an electronic tubular motor, associated with a microprocessor, motor powered by alternating current, which has a extremely compact structuring, designed to be introduced and conveniently solidarity within the corresponding rotary tube that coils the blind, awning or curtain that is treat, said motor being associated with a radio frequency receiver  by which it is activated remotely through the module  control.

The control module materializes in a command radio-control, with an internal electronics that allows the graduation of the exit and closing races of the Installed item, changing direction for upload buttons and down in command, so that these are always in your correct position regardless of whether the engine is installed at right or left of the element, allowing to control high number of engine modules with the same command, regardless of whether These are awnings, blinds and / or curtains.

Each of the modules of the three types previously described will incorporate an 8-bit microprocessor programmed in assembly language, which allows efficient use, minimizing the time needed to perform each operation, allowing to carry out regulations and graduations previously described, and providing a resolution of high precision movement, less than 5 millimeters, which makes such regulation is practically continuous.

Finally, the wind / sun sensor module is it materializes in a weather station equipped with an anemometer and a photosensitive plate, associated with a control electronics that through a radiofrequency module like the ones above described sends a signal to the control module when the speed of wind exceeds a predetermined value, or when the intensity solar also exceeds a certain level, so that the control knob, through an easy-to-use interface and Programming allows you to reprogram the security program using which acts automatically on the elements installed before  strong wind situations, also allowing to select between different programs depending on the season in which we let's find.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example of practical realization of it, is accompanied as an integral part of said description, a single sheet of plans in which with illustrative and non-limiting nature and in its only figure, it has represented a perspective view of the different elements or modules that participate in a system for winding / development of awnings, blinds and the like performed in accordance with the object of the present invention.

Preferred Embodiment of the Invention

In view of the review figure you can observe how in the system of the invention three participate fundamental elements, a motor module (1) a control module (2) and a wind / sun sensor module (3), being able to participate up to twenty one motor modules (1), as will be seen later.

Each module (1), (2), (3) incorporates a 8-bit microprocessor with programming software that allows, among others, the direction of rotation of the engines, independent programming of origin / end of career, a movement resolution of installed elements less than five millimeters, in addition to the possibility of generating frames for simultaneous control of several motor modules (1) through control module (2).

To do this, the different modules (1), (2), (3) communicate with each other through radio frequency signals from amplitude modulated in the 868.35 MHz frequency band, which allows interference reduction and improved link radio with respect to the old 433MHz band. Cited radio frequency circuits will be based on technology SAW

All the aforementioned modules (1-2-3) will present a design compact, which makes the system easily implantable even in conditions of reduced space.
