Production control parameter includes common yarn production control parameter and section length, pitch, multiplying power, train coefficient, endless form, section coloured yarn life
Production control parameter includes Duan Caiping yarns production control parameter and section color bunchy yarn production control parameter, Duan Caiping yarns production control ginseng
Number includes common yarn production control parameter and the colored regular roving feeding of feeding, section coloured silk coefficient, and section color bunchy yarn produces control parameter packet
Include slub production control parameter and the colored regular roving feeding of feeding, section coloured silk coefficient；The section coloured silk coefficient refers to that section coloured yarn is prized
The lenth ratio of yarn section and white yarn section.
12. a kind of control method of RING SPINNING Numerical control system according to claim 9, it is characterised in that：The step
（3）It is middle calculate first motor, the second motor, third motor, the 4th motor, the 5th motor speed mode be：
When carrying out the production of common yarn, calculated first according to the regular roving feeding of the feeding of input and the spun yarn of production are the ratio between quantitative
To total drafting multiple, proparea drawing-off then is calculated in the drafting multiple of total drafting multiple divided by the first break draft area of input
The linear velocity of front roller is calculated according to the design twist of the spun yarn of input and main shaft spindle rotating speed for multiple, then before
Front roller rotating speed is calculated in roller diameter, and the rotating speed of third motor, root are then directly obtained according to the speed ratio of third gearbox
Middle roller rotating speed is calculated according to front roller rotating speed and proparea drafting multiple, is then directly obtained according to the speed ratio of the second gearbox
Rear roller rotating speed is calculated according to middle roller rotating speed and back zone drafting multiple in the rotating speed of second motor, then becomes according to first
The speed ratio of fast case directly obtains the rotating speed of first motor, and turning for the 4th motor is directly obtained according to the main shaft spindle rotating speed of input
The rotating speed of the 5th motor is calculated according to the main shaft spindle rotating speed of input for speed；
When carrying out fancy yarn production, slub is produced, third motor, the 4th motor, the 5th motor rotating speed with it is common
Yarn is consistent when producing, when first motor, the rotating speed of the second motor and common yarn produce when the production of base yarn section in slub
It is consistent, using first motor, the second motor while speedup when the production of ring section in slub, and according to the bamboo inputted
Section multiplying power be calculated first motor at this time, the second motor rotating speed；For Duan Caiping yarns produce, wherein one feeding it is thick
Yarn is fed by middle roller, and another colored rove is fed by rear roller, and at this time by the quantification of general of the rove of middle roller feeding
The regular roving feeding of the feeding inputted when logical yarn production is determined by the quantification of feeding colour rove of the colored rove of rear roller feeding
Amount, when being produced for the white yarn section in section coloured yarn, rear roller stops operating at this time, then proparea drafting multiple is equal to total draft times
Number, middle roller rotation is calculated in proparea drafting multiple according to front roller rotating speed and at this time, then according to the second gearbox
Speed ratio directly obtains the rotating speed of the second motor, when being produced for the color yarn section in section coloured yarn, at this time according to by middle roller feeding
Yarn that rove is obtained through the drawing-off of front draft zone it is quantitative with the color yarn rove fed by rear roller through front draft zone and after before lead
It is quantitative to stretch the sum of the quantitative spun yarn for being equal to inputted production of yarn that the drawing-off in area obtains, calculate separately to obtain first motor,
The rotating speed of second motor；Section color bunchy yarn is produced, when being produced for the base yarn section in section color bunchy yarn, rear roller stops at this time
Rotation stop is dynamic, then proparea drafting multiple is equal to total draft multiple, then the proparea drafting multiple meter according to front roller rotating speed and at this time
Calculation obtains middle roller rotation, the rotating speed of the second motor is then directly obtained according to the speed ratio of the second gearbox, in section coloured yarn
The production of ring section when, at this time according to the yarn that is obtained through the drawing-off of front draft zone of rove by middle roller feeding it is quantitative with after
The color yarn rove of roller feeding through front draft zone and after front draft zone the obtained yarn of drawing-off it is the sum of quantitative be equal to inputted
The spun yarn of production is quantitatively multiplied by inputted ring multiplying power, calculate separately to obtain first motor, the second motor rotating speed.
