Design And Realization Of The Integrated System Of Automatic Computerized Flat Knitting Machine

Full-automatic Computerized flat knitter is high technology equipment in knitting industry, which integrates Computer Numerical Control (CNC), electron technology, mechanical design, motor driver technology, knitting process and software engineering. Computerized flat knitter can knit a lot of complex tissue, which cannot be done by manual knitting machine. Two aspect of knowledge are necessary for successful development of full-automatic computerized knitting machine. Knowing about the trait of knitting industry, the process of knitting and the configuration of the machine are the first point, and using software technology and related control theory is the second. Combining the two aspects tightly can produce computerized knitting machine with perfect performance. Therefore, the main task of the dissertation is to develop the new full-automatic Computerized flat knitter and the control system.This dissertation includes two important parts. The first emphasis of the dissertation is search and realization of the new pattern preparation system of Computerized flat knitter; the second is the design of the controller of Computerized flat knitter.At first, the paper expatiates on domestic and foreign present situations of Full-automatic Computerized flat knitter, explains relative concept of Computerized flat knitter, and gives the goal of this paper and the main content of the paper.Secondly, the paper analyzes the function of the pattern preparation system, synthesizes the latest new-tech and textile technics of the world, adopts the object-oriented design method to make the whole project of the pattern preparation system. Form the analysis of the above, detailed introduction of the key and important modules is given.The objects which are to be controlled are complex and time- restricted, so after analyzing the requirement in control and I/O interface of the system, the dissertation proposes a design of an embedded control system based on ARM,FPGA and Linux for the flat knitter. Moreover, this paper proposes s doable software design on the existed hardware platform,and finishes the software coding. This system was provided with perfect knitter control function.
