【Abstract】 Textile industry is one of Chinese traditional industries. Research on the automaticmachines in Textile industry is of great significance. The automatic knitting machine is anew type of machine in Textile industry. It is a product of mechanical and electricalintegration which is involved in mechanical design, computer technology, electronic drive,automatic control, knitting process, etc. The main content of this paper is the research onthe control system for the embedded automatic knitting machine.Firstly, the background and the significance of the research are stated. Thedevelopment trend and the current research situation of the computer flat knitting machineare introduced in detail. The research contents and the structure of this paper are presented.The composition of the main components for the automatic knitting machine is introduced.The knitting processes and the function requirement of the control system are analysed indetail. Then the control system scheme based on embedded ARM for the automaticknitting machine is proposed.Secondly, the hardware scheme for the control system for the automatic knittingmachine is raised. Host computer using ARM to drive LCD screen as real-time terminalcontroller, the next-bit machine is divided into main control and head control as motordrive controllers.1Mbps high-speed CAN controller is used for data communicationsamong them.Thirdly, the general design of the software for the automatic knitting machine isproposed. Several key problems in the software design are studied and the specificsolutions for them are put forward. The analytical function of the process, the prospectivefunction of the process, the deceleration control for the stepping motor to realize theaccurate positioning and the algorithm for the positions of multiple yarns ensuring that theposition of each yarn is kept at a reasonable value in the knitting process are studied.Finally, the system function test for the embedded automatic knitting machine is done.The study contents and conclusions of the research have been summarized and the further research works have been forecast.更多还原
