异构CAD系统协同构架研究

Collaborative design framework upon heterogeneous CAD systems

针对异构CAD系统间上层操作指令和底层数据结构存在的差异性,在细胞元语义特征造型技术的基础上,提出了一种全新的支持异构CAD系统间同步协同设计的体系结构,并通过一种优先调度机制有效地解决了异构CAD系统间的"写冲突"问题,提高了实时响应性。该思想初步应用在HUST-CAIDS与AutoCAD间的异构协同设计中,证明了其可行性。

Aimed at the differences of operating instructions and data structure upon heterogeneotis CAD systems, and based on the technology of semantic feature modeling, this paper proposed a kind of new architecture which could support the collaborative design of heterogeneous CAD systems. It solved the problem of ＂writing eonflict＂ between heterogeneous CAD systems effectively by a kind of new scheduling policy, improved the efficiency of real-time response. The preliminary applications in the collaborative design between HUST-CAIDS and AutoCAD were introduced to prove the feasibility of the theories above.
