Computerized flat knitting machine the current sweater production industry models . Its main function is braided in claim input signal and the synchronization signal from the machine , issued various control instructions in a timely manner , in order to achieve various specific actions required by the knitting , auto-complete weave . It combines the technology of computer numerical control , software engineering , and the development direction of the knitting machine industry . In this paper , the development of computerized flat knitting machine technology and domestic development status , the analysis of the structure and function of the system of computerized flat knitting machines , ATmega128 MCU - based low-cost solutions for computerized flat knitting machine control system . The system consists of hardware and software components , two . Hardware using the ATmega128 ATMEL Corporation in the United States for the CPU core and peripheral circuit modular design , including the the ATmega128 minimum system module , keyboard and display modules , head motor module , the nose position detection module , needle selection module , yarn guide and turn cloth module , combined with the CAN-BUS interface and SPI interface , easy to operate , and is conducive to the software debugging and development . Software part based CodeVisionAVR C compiler developed , modular design concept , designed mainly include document management , basic device driver , set of part detection, motion control , process parameters , process monitoring function modules . Given detailed circuit schematic and PCB diagram of the control system and circuit diagram to make a principle of interpretation of anti-jamming circuit . Combination of the VVVF thought , to optimize the hardware , the software , site commissioning , and achieved good control effect . Computerized flat knitting machine control system based on embedded or IPC , the computerized flat knitting machine targeted , high integration , and has a higher cost and practicality .
