Abstract
The invention provides a fuzzy control system of an automatic photoelectric weft straightener. The system mainly comprises a PC machine, an RS232 interface unit, a host processing unit, a drive circuit, a motor control circuit, a photoelectric detection head, a signal processing circuit, a multi-path simulation switch and a mechanical execution part. The PC machine connects with the host processing unit through the RS232 interface unit. An ADC interface in the host processing unit connects with the multi-path simulation switch, and the multi-path simulation switch connects with the signal processing circuit. The signal processing circuit connects with the photoelectric detection head which is provided at a fabric position and is used for detecting fabric. The fuzzy control system of the automatic photoelectric weft straightener in the invention employs adaptive fuzzy PID control. Practice shows that the system can carry out automatic detection on skew of weft and bend of weft of thin type, medium thick type cotton or blending fabric and dyed fabrics, automatic weft straightening is realized, and weft straightening precision reaches a requirement of a national-standard excellent product.
Description
Technical field
The present invention relates to the Fuzzy control system of the employed automatic photoelectricity weft straightener of a kind of textile machine.
Background technology
Weft straightener be correct textile in dyeing and finishing process because the weft yarn that technological factor produces is out of shape indispensable equipment.In the textile dyeing and finishing technology; Because the distortion of fabric in operational process is to become in uncertain, nonlinear, time; And performances such as different fabric elasticities, friction factor are different; There are shortcomings such as poor stability, varietal adaptation difference in the weft straightener of domestic production at present, and whole latitude precision can not satisfy industry requirement fully.To textile the distortion in operational process be non-linear, the time characteristics that become, the present invention proposes a kind of Fuzzy control system of automatic photoelectricity weft straightener.
Summary of the invention
The technical matters that the present invention will solve is to overcome the problem that the weft straightener that has domestic production now exists poor stability, varietal adaptation difference, and a kind of Fuzzy control system of automatic photoelectricity weft straightener is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The Fuzzy control system of automatic photoelectricity weft straightener; Mainly comprise PC, RS232 interface unit, Main Processor Unit, driving circuit, circuit for controlling motor, Photoelectric Detection head, signal processing circuit, multiway analog switch and mechanical operating part composition; Wherein the chip model of Main Processor Unit employing is the TMs320LF2407A chip; PC is connected with Main Processor Unit through the RS232 interface unit; ADC interface in the Main Processor Unit is connected with said multiway analog switch, and said multiway analog switch is connected with signal processing unit, and said signal processing unit is connected to the Photoelectric Detection head; And said Photoelectric Detection head is arranged on the fabric position, in order to detect fabric; Said Main Processor Unit is connected with driving circuit simultaneously; Said driving circuit is connected to circuit for controlling motor; And control the drive motor of the curved apparatus for correcting of skew of weft apparatus for correcting and latitude respectively by said circuit for controlling motor, constitute mechanical operating part together by curved apparatus for correcting of said drive motor, skew of weft apparatus for correcting and latitude and fabric; Native system is mainly become by Pc mechanism with Pc machine processes and displays part, accomplishes parameter setting, shows fabric running status etc. in real time; The machinery operating part mainly is made up of DC servo-motor and apparatus for correcting.
The Fuzzy control system of automatic photoelectricity weft straightener of the present invention adopts high performance TMs320LF2407A chip as Main Processor Unit, adopts adaptive Fuzzy PID Control.Practice shows, this system can to slim, medium-thick type is textile or the skew of weft of blend fabric and dyed fabric thereof and latitude is curved detects automatically, and realizes abb finishing automatically, the high-class product requirement that is up to state standards of whole latitude precision.
