虚拟装配系统开发中参数化模型表达与交互意图识别研究

The Parametric Model Expression and Interactive Intention Recognition in the Virtual Assembly System

  • 摘要: 面向教育培训的虚拟装配系统开发经常涉及多同类型任务、多培训模式、多显示终端的任务需求,传统开发方式往往是逐个定制开发. 为了提高重复性开发工作的效率和解决通用性问题,文章凝练了虚拟拆装操作的共性要素,提出了由任务要素、静态要素和动作要素构建的装配序列参数化表达模型,并设计了基于XML数据格式的参数化表达方法;基于此表达方法,研究了装配操作-交互意图的识别机理,实现了演示、练习和考核3种培训模式的人机交互操作的逻辑解析. 减速器虚拟装配案例表明了基于XML数据格式的参数化表达方法可以提高虚拟装配系统开发的效率.

     

    Abstract: The development of the virtual assembly system oriented to education and training usually involves similar tasks, multiple training modes and many terminals, which are usually customized. In order to improve the efficiency and universality of development, the common elements of virtual assembly operations are summarized and a parametric model that includes task elements, static elements and action elements is proposed to describe the assembly operation process. A parametric presentation method based on XML is designed. The recognition mechanism of assembly operation-interactive intention is studied. Based on it, the logical expression and analysis of the three training modes of demonstration, practice and examination is realized. The example for a reducer virtual assembly shows that the parametric presentation method based on XML can improve the efficiency of virtual assembly system development.
