Blade angle zeroing method for louver

2013 
The invention discloses a blade angle zeroing method for a louver. The blade angle zeroing method for the louver comprises the following steps that (1) Whether the current time is in the daytime or at night is judged, (2) a zeroing signal is sent to a motor when the judgment result obtained in the step (1) shows that the current time is at night, (3) the motor lifts blades to a preset height according to the zeroing signal, puts the blades down, and the blades are closed. According to the blade angle zeroing method for the louver, zeroing processing is carried out on the turnover angles of the blades at night, and due to the fact that the zero-degree values of the blades can be inspected every day, accumulated errors caused by long-time turnover of the blades are eliminated, accuracy of turnover of the blades is improved, and the louver can play a role in sunshade and daylighting to the maximum extent.
