Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings:

a portable curtain based on Bluetooth intelligent automatic control comprises a track 1, a transmission box A2, a transmission box B3, a rotating shaft A4, a rotating shaft B5, an annular belt 6, a pulley A7, a pulley B8 and pulleys 9, wherein the transmission box A2 and the transmission box B3 are respectively inserted into two sides of the track 1, an annular belt 6 is arranged between a rotating shaft A4 on the transmission box A2 and a rotating shaft B5 on the transmission box B3, the pulley A7 is fixed in front of the annular belt 6, and the pulley B8 is fixed at the back of the annular belt 6; more than two pulleys 9 are placed in the track 1 between the gaps of the front and the back of the annular belt 6; the lower part of a rotating shaft A4 on the transmission box A2 is meshed and connected with a 12V small-sized stepping motor 11; the pulley A7, the pulley 9, the pulley B8 and the pulley 9 are respectively hung with a curtain cloth 12 through a hook; wall fixing devices 10 fixed with a wall are arranged on two sides of the track 1; the 12V small stepping motor 11, the 12V direct-current stabilized power supply 15 and the voltage reduction circuit 16 are connected in series, and the 12V small stepping motor 11, the photosensitive sensor 13, the Bluetooth module 14 and the voltage reduction circuit 16 are connected in parallel with the STC89C52 single chip microcomputer 17. When the value of the sunlight received by the photosensitive sensor 13 is lower than the set value, the photosensitive sensor determines that the sunlight cannot be irradiated, and drives the 12V small-sized stepping motor 11, so that the curtain is opened. When the sunlight cannot irradiate, the curtain is still not pulled open, and the Bluetooth module 14 can be connected through the mobile phone to open the curtain.
