Method for adjusting the residual light gap between slats of a motorized venetian blind
View Patent ↗A method for adjusting the residual light gap between slats of a motorized blind when oriented in a set closed position of the blind, where at least one closed position of the slats is set by automatic detection using detecting means, comprising the following steps: adjusting a detection criterion of the detecting means, performing anew automatic detection of the closed position with adjusted detection criterion, recording the new value of the detection criterion.
1. A method for adjusting the residual light gap between slats of a motorized blind when oriented in a set closed position, where at least one closed position of the slats is set by automatic position detection using detecting means, comprising the following steps:
adjusting a detection criterion of the detecting means in response to a control action by a user, the control action specifying an adjustment to the orientation of slats in the closed position,
performing a new automatic detection of the closed position with adjusted detection criterion,
recording the new value of the detection criterion; and
associating the new value with the at least one closed position.
2. The method as claimed in claim 1 , wherein the method further comprises a step of receiving an acknowledgement from a user that the current position of the slats of the blind is acceptable to the user.
3. The method as claimed in claim 1 , wherein the detection criterion is a motor parameter.
4. The method of claim 3 , wherein the motor parameter is current draw.
5. The method as claimed in claim 1 , wherein the step of performing automatic detection of at least one closed position comprises driving the slats into a position where further movement requires an increase in torque, without this position being a frank physical stop.
6. The method as claimed in claim 1 , wherein the step of performing automatic detection of at least one closed position comprises controls of torque as well as of instantaneous change in torque.
7. The method as claimed in claim 1 , wherein an individual adjustment of the residual light gap is performed for each closed position.
8. The method as claimed in claim 1 , wherein recording of the closed position is added to the step of recording the new value of the detection criterion.
9. An actuator comprising hardware and software means for implementing the method as claimed in claim 1 .
10. A motorized blind with orientable slats comprising an actuator as claimed in claim 9 .
11. An installation comprising a motorized blind with orientable slats and a remote control unit comprising means to enter in a light gap adjustment mode, wherein the closed position of the slats is adjustable by means of the remote control unit, wherein the remote control can adjust the orientation of slats in the closed position of the slats, wherein the motorized blind includes a detecting means configured to set the closed position of the slats by automatic position detection, and wherein the motorized blind includes an actuator configured to perform the following steps when in the gap adjustment mode:
adjusting a detection criterion of the detecting means in response to a control action by a user, the control action specifying an adjustment to the orientation of slats in the closed position,
performing a new automatic detection of the closed position with adjusted detection criterion,
recording the new value of the detection criterion; and
associating the new value with the at least one closed position.
