Provided is an automatic blind system including an elevation rope configured to elevate the wings of a blind; a rotary drum on which an angle adjustment rope configured to adjust an angle of the wings of the blind and the elevation rope are wound; an angle adjustment drum disposed on one side of the rotary drum; and an electric motor having a shaft on which the rotary drum and the angle adjustment drum are axially installed and configured to selectively rotate the rotary drum or the angle adjustment drum; and the blind system including: a sensor unit (10) configured to detect insolation of sunlight; an accumulative calculation unit (20) electrically connected to the sensor unit (10) and configured to accumulatively calculate insolation of the sunlight detected by the sensor unit (10); an accumulative limit measurement unit (30) electrically connected to the accumulative calculation unit (20) and configured to measure an accumulative limit amount of sunlight calculated by the accumulative calculation unit (20); and a control unit (40) electrically connected to the accumulative limit measurement unit (30) and the electric motor and configured to drive the electric motor to fold or unfold the blind when the accumulated insolation of the sunlight measured by the accumulative limit measurement unit (30) exceeds a limit. Accordingly, when the accumulated insolation of the sunlight is calculated and the accumulated insolation exceeds the limit, the electric motor of the blind is driven to solve the problems such as the increase of a vehicle′s temperature due to the heat of the sunlight during the summertime, excessive supply of the sunlight to a flower pot, or the likes. In addition, as a window to which the direction of sunlight shined is automatically shaded, it is possible to adjust the insolation of the sunlight to where it is excessively shined. |
