Design of control system of multi-function jacquard knitting machine

In order to solve the problems of poor product quality,low efficiency and low level of automation confronted in the multi-function jacquard knitting machine,the working principle of the multi-function jacquard knitting machine is discussed and the operational requirements of each component during knitting is analyzed,then the structure of conventional multi-function jacquard knitting machine is simplified through substituting three servo motors for the mechanical transmission mechanism.Based on the simplified multi-function jacquard knitting machine,the new master-slave control system is developed by using the embedded industrial control computer and digital signal controller,and the control system architecture and the realizing way of both hardware and software are introduced in detail.Additionally,the logic sequence,reliability and performance in real-time are analyzed for the proposed control system,and the corresponding measures are presented from the viewpoint of hardware and software.The application demonstrates that the proposed control system is available,reasonable,stable and reliable,and has high performance and low cost.
