远程产品设计类实时协同模型研究

NOMINAL REAL-TIME COOPERATION OF DISTANT PRODUCT DESIGN

在 Internet网上由于网络带宽限制等多方面的原因 ,远程产品协同设计实时交互是无法达到的 .为此 ,基于现有的软硬件环境及实际需要 ,我们提出了一个“类实时协同”模型 .实践表明 ,该模型便于跨平台工作 。

It is impossible to achieve the real time intercommunion in distant product design because of the limitation of network bandwidth and other reasons over Intemet.A model of 'Nominal Real Time Cooperation(NRTC)'is presented,of which synchronization based on event and time is applied to easily work in different platforms with quicken intercommunion and real time cooperation of effective information through neutral files.There are three mainly contents in NRTC:First,the function of remote calling and mutual speech is realized by existing software.Second,there is a trigger designed for event driver synchronization(an operation for the trigger to cause relative events happen after a certain event or events happens)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 design information through two ways;plug in share and neutral files.By analyzing the experiments,it is indicated the model presented is completely capable.
