Motorized screen configuration and grouped control methods, automatic controller for implementing this method and home automation installation comprising such an automatic controller

1. Method of configuring a group of motorized screens, each motorized screen of the group comprising a load bar that is displaced according to a defined travel, wherein it comprises a step consisting in determining for each screen “n” of the group, a shift parameter between a first reference position of the screen and a second reference position, one of the two reference positions being a reference position common to the screens of the group of screens.

2. Configuration method according to claim 1 , wherein each screen of the group is coupled to a counting means which defines the relative position of the load bar in relation to the first reference position specific to the screen or in relation to the second reference position.

3. Configuration method according to claim 2 , wherein the second reference position is a realignment position of the counting means specific to each screen and in that the first reference position is the reference position common to the group.

4. Configuration method according to claim 1 , wherein the second reference position is the reference position common to the group of screens.

5. Configuration method according to claim 4 , wherein the first reference position of a screen to be configured is a top end-of-travel position of this screen.

6. Configuration method according to claim 1 , wherein it comprises a preliminary step consisting in defining a master screen for the group of screens, this master screen serving as a reference for the execution of the configuration method.

7. Configuration method according to claim 6 , wherein the second reference position is the first reference position of the master screen.

8. Configuration method according to claim 1 , characterized in that it comprises at least the following basic steps:

i). positioning the load bar of a selected screen from the screens of the group of screens at a common reference position of the group;

ii). recording this common reference position;

iii). positioning the load bar of the selected screen in a configuration position corresponding to a particular position of the load bars of the screens to be configured;

iv). recording this configuration position;

and, for each screen of the group,

v). positioning the load bar of the screen to be set at the configuration position of the step iii);

vi). recording this third position; and

vii). using these three recorded positions to determine the shift parameter of the screen to be configured.

9. Configuration method according to claim 1 , wherein it comprises at least the following basic steps:

a) positioning the load bar of a selected screen in a configuration position corresponding to a reference position of a screen to be configured;

b) recording this configuration position,

c) using this record to determine the shift parameter of the screen to be configured.

10. Automatic controller for controlling a group of screens incorporating means of implementing a configuration method according to claim 1 .

11. Home automation installation comprising the automatic controller according to claim 10 , wherein the motorized screens are fabric blinds or venetian blinds.

12. Grouped control method for the displacement of a group of screens comprising at least two motorized screens, each screen of the group comprising a load bar that is displaced according to a predefined travel, characterized in that to obtain, following a control command, at least the alignment of the load bars that have been displaced, this method takes into account at least a shift parameter between a first reference position of a screen and a second reference position, one of the two reference positions being a reference position common to the screens of the group of screens.

13. Grouped control method according to claim 12 , wherein it comprises at least the following steps:

a) following a command to move the group of screens, displacement of at least one load bar of a screen of the group; and

b) following a stop command, positioning the load bar of each screen of the group or of each screen whose load bar has been shifted, so as to obtain at least the alignment of the load bars that have been shifted.

14. Grouped control method according to claim 13 , wherein the movement command of the step a) is a command aiming to displace the load bar to a predefined position and in that the stop command of the step b) is then executed as soon as the predefined position is reached.

15. Grouped control method according to claim 13 , wherein the alignment of the load bars of the step b) is obtained by the displacement of the load bar of each screen to a position determined in relation to a reference position specific to each screen.

16. Automatic controller for controlling a group of screens incorporating means for implementing a grouped control method according to claim 12 .

17. Home automation installation comprising the automatic controller according to claim 16 , wherein the motorized screens are fabrics blinds or venetian blinds.
