Abstract
In the initialization process for the control of the movement of a motorized roller shutter, the travel of the shutter between its two extreme positions is divided into different segments and each segment end is allocated a duration of shutter movement in a first direction between this segment end and a first reference position and a duration of shutter movement in a second direction between this segment end and a second reference position.
Claims11
An initialization process, for determining the position of a screen and for the control of the movement of said screen (2) designed to move between two extreme positions, the screen being associated with a control unit (4) which comprises a clock (6), a memory (5) and a logic processing unit (9) and which controls an actuator (3) driving the screen (2), in which process
- the travel of the screen between the two extreme positions is divided into different segments and
- each segment end is allocated a duration of screen movement in a first direction between the segment end and a first reference position and a duration of screen movement in a second direction between the segment end and a second reference position,
- wherein each position of the screen is determined by the duration separating the screen from at least a reference position.
A screen device (1) designed to move between two extreme positions, a control unit (4) for controlling which comprises a clock (6), a memory (5) and a logic processing unit (9) and controls an actuator (3) driving the screen (2), in which device the logic processing unit executes logic comprising:
- dividing travel of the screen between the two extreme positions into different segments;
- and
- allocating to each segment end a duration of screen movement in a first direction between the segment end and a first reference position and a duration of screen movement in a second direction between the segment end and a second reference position,
- wherein each position of the screen is determined by the duration separating the screen from at least a reference position.
