为克服现有纬编针织物计算机辅助设计(CAD)系统只能在局域网或单机上运行的不足,结合互联网技术和数据库技术,采用C#语言、Javascript语言以及HTMNL5,通过数学建模,开发面向针织产品设计制造全过程的纬编针织物CAD系统.实现了花型意匠图,工艺编织图的在线设计,并能够自动计算生成三角配置图.利用结构化查询语言数据库建立产品数据库高效地存储和管理海量的针织产品数据资源.该系统采用浏览器/服务器结构,并将Web站点和数据存储服务部署到服务器上,客户端零安装、零维护,用户可直接通过电脑或移动智能终端访问Web站点.随时随地在线设计针织物.同时以提花组织设计为例进行了大量实验,结果表明该系统操作方便,数据信息存储更新高效快捷,满足了用户在线设计的需求.%Aiming at the defects of existing computer-aided design( CAD) systems for weft knitted fabric of can only run on a single unit or local area network, a weft knitted fabric CAD system was developed to the needs of the overall process of weft knitted products from design to manufacture by combining the network technology with database technology and adopting the technology of C #, Javascript and HTMNL5. Pattern drafted patterns and the online design of weaving graphs realized, and the arrangement of cams were automatically calculated and generated. And strutured query language( SQL) database was used to efficiently store and manage vast amounts of data resources of knitted products. The browser/server mode, the Web sites and data storage services were all deployed to the server, zero client installation, and zero maintenance were achieved, users can design knitted fabrics online anywhere by accessing the Web sites by a computer or a mobile intelligent terminal. And the fabric weave design was used as an example in the practical test, the test results showed that it is convenient for operation, and the data information storage and updating is efficient and quickly, thereby meeting the needs of online design of users well.
