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