摘要
实时协同设计是网络 CAD发展的关键技术之一。网络带宽和实时性限制了 CSCW技术在工程 CAD中的应用。本文提出了网络环境下实现工程 CAD实时协同的一种模式。首先以现有的成熟软件实现远程呼叫和语音交互 ,然后设计一个触发器 ,通过事件驱动同步和定时连续同步 ,以插件共享方式和中性文件方式实现 Auto CAD信息的实时同步。实践证明 。
The real-time cooperative design is one of the key techniques in network-based CAD. The application of CSCW in CAD in engineering is limited within the bandwidth of network and real-time display. This paper presents a model for real-time cooperation of CAD in engineering over network.. First, the function of long-distance calling and mutual speech is realized by existing software. Then a trigger is designed with the function of event-driven synchronization(an operation for the trigger to cause relative events happen after a certain event or events happen) and timing-sequence synchronization(an operation to cause a series of events to be regularly and continuously performed).. Finally, the trigger is used to implement the real-time synchronization of mutual AutoCAD information through two ways: plug-in share and neutral files. Experiments show that our model is effective.
