Abstract: In order to realize the conversion from computer flat knitting machine design pattern to control data, a kind of control system data preparation method in development of computerize flat knitting machine is introduced by this paper. This method has five parts, including of PAT data, CNT data, SYS data, KSD data, FKD data. This paper illustrates the function of all the data documents and data definition, and give the FKD data conversion algorithm. Most existing pattern of design software flat knitting machine process files can be compatible by this method. FKD data conversion algorithm has small burden of data to control system. FKD data transmission is compact and can be quickly applied in all kinds of master-slave type of computer knitting machine control system. This design has applied to computerize flat knitting machine controller with stability of processing data and excellent performance.
