Abstract:

In view of problems of existing jacquard circular knitting machines' problems now, such as low patterns' safety and no intuitive display on production field and so on, this paper has a research on patterns' encryption and decryption based on RSA algorithm and proposes a design which is an embedded display system of jacquard circular knitting machine's pattern. This paper discusses patterns' encryption and decryption algorithm, the design and realization of converting pattern data to bitmap on Windows CE embedded operating system and the design of pattern's display system. Proved by production field's using, the jacquard circular knitting machine's pattern's embedded display system can display patterns intuitively and ensure the safety of pattern file transfer by encryption algorithm, which solves the problems which are security of new sample cloth pattern file and display on machine on production field.

Key words: jacquard circular knitting machine, RSA algorithm, pattern intuitive display, encryption algorithm
