Abstract
A process for initializing a motorized roller shutter that moves between two extreme positions includes moving the shutter in a first direction at fast speed, then moving it at slow speed, then reversing it in a second direction at fast speed followed by slow speed. The shutter is moved back in the first direction at fast speed, then at slow speed, after which the times are determined that are needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction.
Claims15
A process for initializing a device (1) comprising a screen (2) designed to move between two extreme positions, an actuator (3) capable of driving the screen at two different speeds, and a control unit (4) comprising a clock (6) that measures for how long the screen is in movement, a memory (5), and a logic processing unit (9) controlling the actuator, which process comprises at least the following steps:
- moving the screen in a first direction at fast speed for a fast speed first duration (T1) such that the screen does not reach a first extreme position, moving the screen in the first direction at slow speed until it reaches the first extreme position, and record this duration as slow speed first duration (t1), moving the screen in a second direction at fast speed for a fast speed second duration (T2) such that the screen does not reach the second extreme position, moving the screen in the second direction at slow speed until it reaches the second extreme position and record this duration as slow speed second duration (t2), moving the screen in the first direction at fast speed for the fast speed first duration (T1), moving the screen in the first direction at slow speed until it reaches the first extreme position and record this duration as slow speed third duration (t3), and calculating the times needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction using the first and second fast speed durations (T1, T2) and the recorded slow speed first, second, and third durations (t1, t2, t3), wherein the control unit (4) determines a screen position based on a duration of activation of the actuator.
A device (1) comprising a screen (2) designed to move between two extreme positions, an actuator (3) capable of driving the screen (2) at two different speeds, and a control unit (4) comprising a clock (6) that measures for how long the screen is in movement, a memory (5), and a logic processing unit (9) controlling the actuator, wherein the logic processing unit (9) executes logic comprising:
- moving the screen in a first direction at fast speed for a fast speed first duration (T1) such that the screen does not reach a first extreme position, moving the screen in the first direction at slow speed until it reaches the first extreme position and record this duration as slow speed first duration (t1), moving the screen in a second direction at fast speed for a fast speed second duration (T2) such that the screen does not reach the second extreme position, moving the screen in the second direction at slow speed until it reaches the second extreme position and record this duration as slow speed second duration (t2), moving the screen in the first direction at fast speed for the fast speed first duration (T1), moving the screen in the first direction at slow speed until it reaches the first extreme position and record this as slow speed third duration (t3), and calculating the times needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction using the first and second fast speed durations (T1, T2) and the recorded slow speed first, second, and third durations (t1, t2, t3), wherein the control unit (4) determines a screen position based on a duration of activation of the actuator.
A process for initializing time-controlled extreme positions of a device (1) comprising a screen (2) designed to move between two extreme positions, an actuator (3) capable of driving the screen at two different speeds, and a control unit (4) comprising a clock (6) that measures for how long the screen is in movement, a memory (5), and a logic processing unit (9) controlling the actuator, which process comprises at least the following steps:
- moving the screen in a first direction at fast speed for a first duration such that the screen does not reach a first extreme position, moving the screen in the first direction at slow speed until it reaches the first extreme position, moving the screen in a second direction at fast speed for a second duration such that the screen does not reach the second extreme position, moving the screen in the second direction at slow speed until it reaches the second extreme position, moving the screen in the first direction at fast speed for the first duration, moving the screen in the first direction at slow speed until it reaches the first extreme position, and using data from these movements of the screen to calculate the times needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction, wherein the control unit (4) determines a screen position based on a duration of activation of the actuator.
