Abstract:

Imported pattern system almost has monopolized the pattern preparation technology of seamless underwear knitting machine through data encryption. In order to meet the requirement of domestic underwear design and manufacture, a system including pattern and action preparation for underwear knitting machine is designed, and a compression algorithm, an encryption algorithm and data analysis are used in this system for solving the problems of data security and space using. The pattern preparation system is divided into a pattern design subsystem and a chain action subsystem. In pattern subsystem, a bitmap similar to structure diagram shows the structure of knitting fabric, and a yarn finger bitmap shows the movement of yarn finger. In chain action subsystem, a series of data structures is designed according to the knitting technology and process of machine actions to express the data of chain action file. It is verified that the system is convenient, fast and efficient for design of underwear knitting. And the data file is space-saving , safe and reliable transmission.

Key words: underwear knitting machine, data analysis, compression algorithm, encryption algorithm
