摘　　要：本文针对基于Web3D的协同设计系统中多用户协作冲突处理、设计操作实时同步显示和交互过程即时通讯3个关键问题进行研究。针对3个问题分别提出基于控制权限及优先级处理的冲突操作解决方案,基于约定语义规则库进行设计操作格式化与数据解析和基于node.js+socket.io即时通信框架的客户端与服务器通讯方案,从而实现基于Web3D的协同设计系统中操作与数据的一致性与即时性。Multi-user collaboration conflict management,real-time synchronous display of design and operation and instant messaging of interactive process are three key issues for the research of Web 3 D-based co-design system. According to the three problems, the paper proposes conflict operation solution based on control authority and priority,respectively. Based on the agreed semantic rule base,the paper designs and formats operation and data analysis and client/server communication scheme based on node.js ＋ socket. io instant messaging framework. The consistency and immediacy of operation and data in Web 3 D-based collaborative design system is achieved.
