In step S101, start and fly shuttle rotating disk, Real-time Obtaining is from the photosensitive value of photoelectric conversion device output;
In step S102, when photosensitive value is greater than sensitization upper threshold, the position of the position of more current rotating disk open-work and last rotating disk open-work, flies the rotation direction of shuttle rotating disk described in determining;
In step S103, when the value of step-by-step counter equals stepping control constant, according to described rotation direction and the velocity of rotation that flies shuttle rotating disk, formation control instruction also sends.
Fig. 8 shows the judgement flow process that flies shuttle dial rotation direction, and details are as follows.
First, obtain photosensitive value (A/D value or PWM dutycycle) Sen1, Sen2, the Sen3 of 3 photosensitive head outputs.Wherein, Sen1 is the photosensitive value of a bottom photosensitive head, the photosensitive value that Sen2 is middle photosensitive head, and Sen3 is the photosensitive value of the photosensitive head in the top.
Then, sensitization upper threshold Lon is set, if the photosensitive value of photosensitive head higher than sensitization upper threshold Lon, represents the luminous major part that this photosensitive head respective leds is sent, from open-work, appears.2 zone bit Fse1, Fse2 are set, Fse1 position of printing opacity from open-work once before representing wherein, Fse2 represent current from open-work the position of printing opacity.
Then, by Sen1, Sen2, Sen3 respectively with Lon comparison.If all lower than Lon, do not processed, continue to obtain the photosensitive value of photosensitive head.If Sen1 is higher than Lon, first the value of Fse2 is assigned to Fse1, then Fse2 is set to 1, i.e. Fse2=1, the hole that represents current printing opacity is nethermost open-work; In like manner, if Sen2>Lon, Fse1=Fse2, Fse2=2, the open-work of the hole that represents current printing opacity in the middle of being; If Sen3>Lon, Fse1=Fse2, Fse2=3, the hole that represents current printing opacity is uppermost open-work.
Finally, compare Fse1 and Fse2.If Fse1=3 and Fse2=1, or Fse1<Fse2, fly shuttle rotating disk and clockwise rotate, Vol=1; If Fse1=1 and Fse2=3, or Fse1>Fse2, fly shuttle rotating disk and rotate counterclockwise, Vol=0.
Fly the judgement of shuttle dial rotation direction and finish, continue the judgement of next round direction.
Fig. 9 shows according to flying the flow process that the instruction of shuttle dial rotation formation control is controlled, and details are as follows.
First, obtain photosensitive value Sen1, Sen2, the Sen3 of 3 photosensitive head outputs.
Sensitization Xiamen limit value Loff is set, if the photosensitive value of photosensitive head lower than sensitization Xiamen limit value Loff, represents this photosensitive head respective leds, by some or all of, is blocked.
Sen1, Sen2, Sen3 are contrasted with aforementioned sensitization upper threshold Lon respectively.
If Sen1, Sen2, Sen3 are less than Lon, then Sen1, Sen2, Sen3 are contrasted with sensitization Xiamen limit value Loff respectively.If Sen1, Sen2, Sen3 are less than Loff, represent that 3 LED lamps are all blocked, stepping zone bit Fstep is set to 0, i.e. Fstep=0.Stepping zone bit is used for indicating that LED light is in the state of appearing or is blocked state, by the variation of this two states, switches, and can judge the moving situation of rotating disk.Photosensitive value is more than or equal to sensitization upper threshold always, or while being less than or equal to sensitization Xiamen limit value always, the step-by-step counter number of ignoring, can prevent from like this controlling because of the mistake that rotating disk shake causes, such as Fstep=1, and do not change, and represented that dial rotation was not also greater than the distance in 1 hole, step-by-step counter is not counted.If Sen1, Sen2, Sen3 have, be greater than sensitization Xiamen limit value Loff, also motion does not put in place, does not process, and continues to detect photosensitive value.
Sensitization upper threshold Lon and sensitization Xiamen limit value Loff need to arrange according to system actual conditions and the adjustment of rotating disk open-work situation, if improper (such as Loff arranges too low) is set, may cause determining rotating disk motion state.
If Sen1, Sen2, Sen3 have, be greater than Lon, further judge whether Fstep equals 0, if be not equal to 0, represent that the hole of the current printing opacity of rotating disk does not also turn over the scope of LED, do not process, continue to detect photosensitive value.If equal 0, represent to proceed to LED region, rotating disk motion state changes, and stepping zone bit Fstep is put to 1, and step-by-step counter Step is added to 1.
Step-by-step counter Step and stepping control constant CSTEP contrast, wherein step-by-step counter and stepping control constant are for controlling the response speed of last adjustment.For example, when CSTEP=1, fly the distance that shuttle rotating disk often turns over a hole, all once adjust, now the fast response time of photoelectric flying shuttle control system; When CSTEP=10, fly the distance that shuttle rotating disk often turns over ten holes, just once adjust, now the response speed of photoelectric flying shuttle control system is slower.So, when Step equals CSTEP, form corresponding steering order and be sent to controlled device, control up and down or add and subtract the operations such as adjustment; If unequal, continue to detect photosensitive value.
