CAN bus-based modular control system for carriage of flat knitting machine

In order to meet the networking,modular and high-speed requirements of the development of computerized flat knitting machine,a control system of the carriage of flat knitting machine based on CAN bus was designed.Through analyzing feasibility of CAN multi-node communication,CAN network topology structure of the carriage control system was proposed.It used bus node priority scheduling method to improve the real-time property of CAN.According to loop-forming mechanism,modular design was adopted.It made a control module be a CAN node in the CAN communication network.The CAN driver and the main programming based on commands parsing were presented.The control system running indicated that it had a reliable communication,and easy scalability.
