Curtain control system, curtain having the same, and curtain control method

Abstract

A curtain control system, installed in a curtain, comprises a sensing module, a processing module, and a motor control module. When a processing unit of the processing module determines that a rotation angle common to a plurality of panel holders falls within a specific range or that a change in the rotation angle reaches a specific value, and the rotation angle is not equal to a preset angle, the motor control module drives a travel motor and a tilt motor to operate simultaneously.
