Design of Yarn Tension System and Jacquard Knitting Machine

In view of high fault rates of tension control system in the traditional circular knitting machine, this paper proposes and develops one kind of monolithic integrated circuit yarn tension control system. By using the FTA method to analysis systematically each kind of trouble cause in yarn tension system, and analysis influencing reliable factor of real-time control system, established fault tree the circular knitting machine tension control system. Based on the MCU technology, the sensor network in the program is constituted by ordinary sensor node, the sink node and network coordinator, and responsible for acquiring and transmitting condition information of circular knitting machines. The tension control system has been entered experiment movement with good performance, it is indicated that the this study is benefit to enhance the reliability of yarn tension system.
