Emitting；
Single chip control module 1 connects motor 3 by motor drive module 2, and the rotating shaft of motor 3 is cased with the annular scraps of paper 7,
The annular scraps of paper 7 rotate with the rotating shaft of motor 3, and infrared photoelectric sensor 4 is fixed on the top of the annular scraps of paper 7, infrared photoelectric sensing
Device 4 connects single chip control module 1；Power module 5 connects single chip control module 1 and motor drive module 2；
Infrared photoelectric sensor 4, for the rotation according to the annular scraps of paper 7 being decorated with chequered with black and white candy strip, output
Analog voltage waveshape signal；
Single chip control module 1, for receiving the analog voltage waveshape signal of infrared photoelectric sensor 4 output, through undue
Analysis is calculated corresponding impulse waveform, and the umber of pulse further according to impulse waveform is calculated motor 3 rotation distance, and by inspection
The high level time change surveying impulse waveform still diminishes to judge motor 3 traffic direction, thus sending to motor drive module 2 greatly
Control signal；
Motor drive module 2, for receiving the control signal of single chip control module 1, thus the work shape of controlled motor 3
State.
The stroke of electrically driven curtain that this utility model provides and hand pull starting-up direction detection device also include remote control module 6,
Remote control module 6 connects single chip control module 1 by communication.This device can also not only by remote pilot
Manually control, more convenient to use.
The corresponding radian of white stripes of the annular scraps of paper 7 is all identical, and the radian of adjacent black striped is along clockwise
Direction becomes larger or diminishes；Or,
On the annular scraps of paper 7 along clockwise direction on be decorated with the chequered with black and white striated section of at least 2 groups identicals, every group of identical is black
The radian of the adjacent black striped in alternate striated section becomes larger along clockwise direction or diminishes in vain.
When electrically driven curtain is opened, the umber of pulse that single chip control module 1 is produced when being rotated by detection determines motor 3
The distance run, when this umber of pulse is equal to the electronic journey umber of pulse setting, illustrates that curtain fully opens, single-chip microcomputer control
Molding block 1 is automatically stopped work by controlled motor drive module 2 controlled motor 3.In the same manner, when electrically driven curtain is closed, pass through
The electronic journey of setting, when completely closing, motor 3 is automatically stopped work.
When manual pulling curtain, window curtain driving motor 3 rotates, and single chip control module 1 compares impulse wave by detection
In shape, black vaginal discharge time length to be determining motor 3 direction of motion, thus start motor 3 moving towards handss pull direction.
Embodiment
As shown in figure 1, whole corresponding radian of white stripes of the annular scraps of paper 7 is all 10 °, edge on the annular scraps of paper 7
It is decorated with clockwise the chequered with black and white striated section of 3 groups of identicals successively, the chequered with black and white striated section of every group of identical includes 4 arcs
The blackstreak that degree angle becomes larger along clockwise direction or diminishes, respectively 8 ° of the corresponding radian of 4 blackstreaks,
16°、24°、32°.
When the annular scraps of paper 7 together rotate with motor 3, infrared photoelectric sensor 4 exports different analog voltages, when complete
During all black, the voltage of output is vcc, when white completely, the voltage 0 of output.
The outfan of photoelectric sensor is connected to the ad acquisition port of single chip control module 1, and single chip control module 1 gathers
Its analog voltage, using software design patterns threshold value, voltage, more than vcc/2, is shown to be motor 3 and goes to black zones, voltage is less than
Vcc/2, shows that motor 3 has gone to white area.After the collection of single chip control module 1 differentiates, form impulse waveform.Single
Piece machine control module 1 is passed through to calculate its umber of pulse, can obtain motor 3 rotation distance and electrically driven curtain range ability (stroke),
When electrically driven curtain fully opens or completely closes, motor 3 is allowed to stop by single chip control module 1 controlled motor drive module 2
Under.
Single chip control module 1 still diminishes to differentiate that motor 3 is transported greatly by detecting that the high level time of impulse waveform becomes
Line direction.When motor 3 runs towards direction a, single chip control module 1 can produce waveform as shown in Figure 4, when motor 3 is towards another
When one direction b runs, single chip control module 1 can produce waveform as shown in Figure 5.Single chip control module 1 passes through detection 4
Individual continuous high level time data d1, d2, d3, d4, to differentiate the traffic direction of motor 3, differentiate the traffic direction of motor 3
Rule is as follows:
As shown in figure 4, when the data collecting is d4 > d3 > d2 > d1, motor 3 runs towards direction a；
When the data collecting is d3 > d2 > d1 > d4, motor 3 runs towards direction a；

As shown in figure 5, when the data collecting is d1 > d2 > d3 > d4, motor 3 runs towards direction b；
When the data collecting is d4 > d1 > d2 > d3, motor 3 runs towards direction b；
When the data collecting is d3 > d4 > d1 > d2, motor 3 runs towards direction b；
When the data collecting is d2 > d3 > d4 > d1, motor 3 runs towards direction b.
When pulling dynamic curtain one segment distance, window curtain driving motor 3 rotates, wherein during a smaller segment distance, handss
Draw curtain to run can regard as at the uniform velocity.Therefore, single chip control module 1 can also by the high level that compares impulse waveform when
Between data d1, d2, d3, d4 to determine motor 3 rotation direction, so that it is determined that pulling direction, motor 3 is opened towards the side of pulling with this
To operation.Differentiate that the rule of the traffic direction of motor 3 is as follows:
As shown in figure 4, when the data collecting is d4 > d3 > d2 > d1, motor 3 pulls to direction a；
When the data collecting is d3 > d2 > d1 > d4, motor 3 pulls to direction a；
When the data collecting is d2 > d1 > d4 > d3, motor 3 pulls to direction a；
When the data collecting is d1 > d4 > d3 > d2, motor 3 pulls to direction a.
As shown in figure 5, when the data collecting is d1 > d2 > d3 > d4, motor 3 pulls to direction b；
When the data collecting is d4 > d1 > d2 > d3, motor 3 pulls to direction b；
When the data collecting is d3 > d4 > d1 > d2, motor 3 pulls to direction b；
When the data collecting is d2 > d3 > d4 > d1, motor 3 pulls to direction b.
