Abstract
Fuzzy control technique used in embroidery machine belongs to the field of industry automation control. Existing main circuit board used in industry control area can control principal axis motor, X direction step motor and Y direction step motor as well as peripheral unit and screen display. With fuzzy control technique being adopted, the following new hardware and software needs to be added: isolating board and I/O board where there are isolating circuit and I/O circuit respectively. There is software on the new hardware. The control flow of software on the software is follows. (1) conventional method is used to display system status, reset and display color and speed. (2) Maximum speed is displayed by adjusting the keyboard. (3) According the requirement of designed software, movements of controlled principal axis motor, X direction step motor and Y direction step motor are adjusted and improved. So, the movement curve is smoother, the spinning is more stable and rotating speed is higher than before, thereby, the quality of needlepoint and working efficiency has been improved.
Description
(1) technical field
The invention belongs to industrial automation control field, specially refer to the application of fuzzy control technology on embroidery machine.
(2) background technology
The Intelligent Control Theory that begins the end of the seventies and the research of the theory of large scale system and application are the developing of modern control theory on the degree of depth and range, receive various countries scholar's very big concern.Since the eighties, require High Level day by day along with the complicated of automatic control system controlled device and to control performance, when arriving to a certain degree, complexity and accuracy will be repelled mutually, want accurately to describe any physical phenomenon and the motion state of complex object and system, in fact it is impossible to have become, key is how to make accurately and between simple and clear to average out, make the description of problem have practical significance, the ambiguity of this description is not only harmless to finding the solution of problem, and can make right judgement and processing to complexity expeditiously, therefore, the research of fuzzy control theory and application have consequence and meaning in modern automation field.
Along with development of computer, modern control theory also is used widely in extensive linear multivariable system,, but for complicated nonlinear system, original control strategy but is difficult to be suitable for.Fuzzy control is not only applicable on a small scale linear single-variable system, and gradually to extensive, complicated nonlinear system expansion, it have be easy to be familiar with, output quantity is continuous, reliability is high, can bring into play the advantages such as good automation effect that skilled expert operates.
The research work of China's fuzzy control theory and application facet thereof is since 1979, so far existing two times about ten years, its achievement in research is used and is mainly concentrated on the industrial furnace aspect, as annealing furnace, electric smelting furnace, cement kiln and development afterwards to the control of paper machine etc.And for the automatic control of embroidery industry, also beyond example the theory and the technology of this fuzzy control really is useful in the production practices up to now.
Computerized emboridering machine is a kind of high accuracy number electromechanical integration equipment, and its core is the computer control part, and head motor, X, Y stepping motor all are the executing agencies of computer control.Computer control constitutes embroidery pattern according to the displacement of programming style control head motor rotation and X, Y stepping motor by needle tracking.
Adopt the embroidery machine computer controller of traditional control model can only guarantee under slow-speed of revolution running higher embroidery quality is arranged, computer controller then can not guarantee the embroidery quality under high speed conditions.This mainly is because when rotating speed raise, the acceleration and deceleration control of the tension force of embroidery line, stepper motor all became very complicated, adopts traditional control algolithm to be difficult to obtain outstanding control data.Fuzzy control technology adopts the computer controller of fuzzy control technology design having stronger advantage aspect the solution complex object problem, can guarantee to have outstanding control data and separate under high rotation speed operation, thereby guarantee higher embroidery quality.
At present, domestic embroidery machine electric control system, no matter be the high-grade automatically controlled of very color big liquid crystal display, still common is economical automatically controlled, its core still adopts the Single-chip Controlling principle, improve constantly in the embroidery machine performance, today that function is constantly strengthened, want to further develop and widen and to be restricted, this research group will blur the electronic control technology developing and be applied in the embroidery machine control system, designed the fuzzy control computer software, to spindle motor, X and Y control respectively with single-chip microcomputer to stepper motor and peripheral control section, have improved spindle motor, the curve movement of stepper motor (referring to Fig. 1 a.1b), expression adopt the variation of fuzzy control technology front and back step motion curve, simultaneously, the application of fuzzy control provides the function extending space.
(3) summary of the invention
In order to solve in existing embroidery machine electric-control system, the embroidery operating efficiency is further improved and the further suffered restriction of optimization of embroidery quality, just wish to utilize the control principle of fuzzy mathematics, redesign embroidery machine electric-control system also carries out the fuzzy control of computer software, improve the curve movement of spindle motor, stepper motor, the space of function expansion is provided, optimizes the embroidery quality.For solving this purpose, realize by the following technical solutions, the application of a kind of fuzzy control technology on embroidery machine, comprise existing industrial control mainboard to spindle motor, X to stepper motor, Y to the control of stepper motor and peripheral cell and to the control of display, it is characterized in that, behind the employing fuzzy control technology, need on original hardware device, set up new hardware, be provided with mainboard, which is provided with motherboard circuit; Also set up division board and I/O plate, buffer circuit is arranged respectively on it, the I/O circuit is solidified with computer software on the adding hardware, and the control flow of this software is: according to a conventional method the display system state, reset, Show Color and speed; Regulate keyboard and show maximal rate, regulate according to design software and improve the step motion curve, move frame to smooth state; Entering back and stop embroidering the some program, enter determining program again, is then to continue back to stop embroidering a little; , then do not enter the embroidery program.
Set up a division board between described mainboard and the I/O plate and avoid the bottom top to be influenced, protected the safety of industrial control mainboard and mainboard effectively, improved the security of system because of cause specific.
The beneficial effect of the technical program is, pass through fuzzy control technology, make controlled spindle motor, X more become level and smooth to the stepper motor curve movement to stepper motor, Y, rotate more steady, under the same mechanical condition, improve rotating speed, thereby improved the mechanical operating efficiency and the quality of embroidery product.
