无缝针织内衣机的花型准备系统及数据安全

Pattern preparation system of seamless underwear knitting machine and data security

因进口花型制版系统通过加密垄断了针织无缝内衣机的工艺制版技术,为满足国内针织无缝内衣设计生产的需求,设计了一套针对无缝针织内衣机花型及链条动作的数据准备系统,并提出了一种文件数据压缩、加密、解析的算法,以解决数据安全性和大容量问题。花型准备系统分为花型子系统和链条动作子系统,花型子系统用类组织意匠位图表示织物的组织结构,用色彩位图表达编织过程中纱嘴动作;根据无缝针织内衣机的编织工艺、动作流程,为链条动作子系统设计了一系列数据结构表达链条动作文件数据。经现场制版验证,花型设计方便、快捷、高效,花型文件数据小,传输安全可靠。

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.
