Procedure for controlling motor-driven darkening devices, especially for positioning of lamellae of Venetian blind

摘要

A procedure for controlling motor-driven darkening devices, especially for the positioning of lamellae of a Venetian blind (1), has full-wave control used for the motor (3). Preferred Features: A phase detection of the supply voltage is undertaken. An adjustment position is specified and this is controlled by a set point-actual value comparison. The change of position takes place at variable speed. For the set point-actual value comparison, at least one signal of at least one sensor is used. The control takes place via a microprocessor. A matching to different motor types and/or sensor types takes place by changing the control program. There is also a programmable program store, a power end stage and a voltage supply.
