Abstract: Aiming at the problem of multi actuators and carding devices of jacquard pile knitting machine, complexity of the traditional control circuit and mutual interference in drive circuit, a design project of control system for jacquard pile knitting machine based on multi bus structure was proposed through the research of working principle and control requirements of pile knitting machine. The key hardware design and software development of control system, and a plan used to deal with feed, needle selection and pattern data were discussed. The extraction method of data of needle selection and feed was put forward to satisfy with jacquard fur′s weave requirement. A calculation for the feed with certain lead of carding device′s stepping motor was stated through analysis of working principle of carding device′s mechanism. The results indicate that the control system is stable in operation, and it has a reliable communication, strong anti jamming ability and good extension.

 

Key words: multi bus structure; jacquard fur; deal with data of needle selection; feed with lead
