Optical shade controller system for controlling a roller shade using a variable linear velocity |
摘要 |
Presented is a system for controlling a roller shade. The system includes a flexible shade material having a lower end, a roller tube windingly receiving the flexible shade material, and a reversible motor for rotating the roller tube to move the lower end of the shade material between a first and second position. The system further includes an optical sensor for capturing an image frame of the shade material at a plurality of linear positions as the lower end of the flexible shade material moves from the first position to the second position. The system further includes a motor controller for controlling the reversible motor to move the lower end of the shade material from the first position to the second position using a variable linear velocity profile in response to position information obtained from the plurality of captured image frames.
