船舶生产设计供图管理软件开发

Software Development of the Supply Management of Drawings for Ship's Production Design

针对船舶建造过程中缺乏形象直观的设计供图软件,采用word等软件编辑时需用手工计算修改多个日期值的现状,设计自定义扩展属性的日期节点及连接线组件,构造并实现图形对象拾取算法、关联对象联动排版布局算法及对象干涉检测算法等,以vb.net语言为开发工具,构建船舶生产设计过程中的大节点排程及图纸文档进度的可视化管理软件系统,实现日期节点排程联动计算等功能。采用FTP文件存储结构提高了设计图纸文档的存储效率,并采用在中间层加/解密的处理方法,既保证了图纸文档的信息安全,又减少了对访问文档对象效率的影响。

During the shipbuilding process,a lack of drawings provision software makes the workers always use the Word to create and edit drawings provision schedule and modify the dates manually. So a date and connection-line assembly with customized properties is designed,and the algorithms to obtain graphic object,layout related objects with linkage and check out the collisions between objects are constructed to realize a visual management system to develop main nodes schedule which includes the needed drawings and documents during ship production by vb. net programming language. The system stores files by FTP technique to improve storage efficiency,and introduces encryption method on middleware to assure information security and reduce the influence on documents access.
