Curtain adaptive adjusting method

Abstract

The invention discloses a curtain adaptive adjusting method; the curtain comprises a cord fabric, a rotary shaft, a photosensitive sensor, and a stepping motor; the top of the cord fabric is connected with the rotary shaft; the output end of the stepping motor is connected with the rotary shaft; the photosensitive sensor is arranged in the room; in adjustment, firstly light intensity value in the room is obtained, and compared with a preset object light intensity value; if the real value is bigger than the preset value, the difference value is obtained; if the difference value is bigger than a preset light difference threshold, the stepping motor is controlled to drop the cord fabric until the difference value is smaller than or equal to the preset light difference threshold; if the real light intensity value is smaller than the preset object light intensity value, the difference value is obtained, and if the difference value is bigger than the preset light threshold, the stepping motor is controlled to raise the cord fabric until the difference value is smaller than or equal to the preset light difference threshold. The curtain adaptive adjusting method is simple in structure, convenient in usage, can automatically adjust the opening level of the curtain, and no manual adjusting is needed.
