摘要： 动态数据交换是实现网络协同设计的关键技术，在协同设计中每一步的设计信息都进行实时交换必然导致在动态数据交换中包含不必要的数据。为了解决这个问题，该文提出基于ECA规则的动态数据交换技术。建立基于ECA规则的动态数据交换系统结构，并定义动态数据交换中的ECA规则和动态数据更新中事件间的基本关系。应用该技术实现了跨平台异构CAD系统之间动态数据的实时交互和一致性。

Abstract: The dynamic data exchange is the key technique to realize the Internet supported collaborative design. But the information of each step designing in collaborative design needs to exchange real timely, so many unnecessary data must be contained in dynamic data exchange format. To resolve the problem, the dynamic data exchange technique based on ECA is proposed. The system structure of dynamic data exchange based on ECA is constructed. The ECA rule in dynamic data exchange and the basic relation of events are defined. The dynamic data exchange technique based on ECA is applied to realize the real-time exchange and consistency of the dynamic data between the heterogeneous platforms and CAD systems.

Key words: network-based collaborative design, dynamic data exchange, Event-Condition-Action (ECA)
