Embodiment
[0032] like figure 1 As shown, the radian angles corresponding to all the white stripes of the ring-shaped paper 7 are 10°, and the ring-shaped paper 7 is sequentially drawn with 3 groups of identical black and white stripes in a clockwise direction, and each group of the same black and white stripes The top includes 4 black stripes whose radian angles gradually increase or decrease along the clockwise direction, and the corresponding radian angles of the 4 black stripes are 8°, 16°, 24°, and 32° respectively.
[0033] When the annular paper 7 rotates together with the motor 3, the infrared photoelectric sensor 4 outputs different analog voltages. When it is completely black, the output voltage is VCC, and when it is completely white, the output voltage is 0.
[0034] The output terminal of the photoelectric sensor is connected to the AD acquisition port of the single-chip microcomputer control module 1, and the single-chip microcomputer control module 1 collects its analog vo...

The invention provides a route and hand-pulling start direction detection device of an electric curtain. The detection device comprises a single chip microcomputer control module, a motor drive module, a motor, annular paper pieces drawn with black-white-alternating stripe patterns, an infrared photoelectric sensor and a power module, and the black-white-alternating stripes drawn on the annular paper pieces are in a radiation shape with the annular circle center as the center. The single chip microcomputer control module is connected with the motor through the motor drive module, a motor rotating shaft is sleeved with the annular paper pieces, the annular paper pieces rotate along with the motor rotating shaft, the infrared photoelectric sensor is fixed to the position above the annular paper pieces, and the infrared photoelectric sensor is connected with the single chip microcomputer control module; the power module is connected with the single chip microcomputer control module and the motor drive module. The route and hand-pulling start direction detection device of the electric curtain is easy to mount, low in cost and high in route accumulation precision.
Description
technical field [0001] The invention belongs to the technical field of electric curtains, and in particular relates to a detection device for the stroke of electric curtains and the direction of manual start. Background technique [0002] With the continuous improvement of living standards, electric curtains are also continuously used in some high-end hotels and villas. Electric curtains can be controlled in a variety of ways, including wired switch control or wireless remote control to control its automatic switch. When the electric curtain is opened, it can automatically stop when it is fully opened through the set electronic stroke. When the electric curtain is closed, it can automatically stop when it is completely closed through the set electronic stroke. The electric curtain can be measured by measuring the number of revolutions of the motor itinerary. When the curtain is pulled by hand, the curtain drives the motor to rotate, and some methods can be used to detect t...
