【摘要】 SOA(Service Oriented Architecture)已广泛应用于传统信息系统领域。如何将SOA思想应用于社会上广泛存在的分布式控制系统的构建,是服务计算领域的一个新的研究课题。针对分布式控制系统的特点及面向服务的思想,提出一种可有效解决消息可靠性传输、服务实时性处理的层次化实时SOA模型,给出各层次模型的详细思路与实现机制。基于该模型,设计并实现了电力配网自动化系统的底层多网络冗余实时消息总线原型系统,并给出了相关结论。更多还原

【Abstract】 SOA(Service Oriented Architecture) has been used wildly in traditional information system area.But how to construct a distributed control system widespread used in our society with the novel idea SOA is a new issue in service computing research area.With the characteristics of distributed control system and SOA,we proposed a layered real-time SOA model which could improve message transport reliability and real-time service processing.We discussed its detailed mechanism on message model,message transportation and service processing.Based on this model,we deve-loped a multi net redundant real-time message bus prototype system for power distributed automation system and gave our results.更多还原
