针对当前设备远程监测与故障诊断系统日趋复杂的业务逻辑和功能需求，本文提出了一种基于SOA的设备远程监测与故障诊断系统的体系结构，依据面向SOA的设计思想，通过对远程监测与故障诊断系统的业务逻辑和功能需求进行不同层次、不同粒度的抽象和划分，建立了一个松散耦合的Web服务系统，并给出了各个核心功能模块的设计和实现方案。最后，本文设计并实现了一套演示系统验证了整个体系结构的可行性。

On the basis of analysis for increasingly complex of services logic and functional requirements for the equipment remote monitoring and fault diagnosis system, a new system architecture based on SOA is proposed for the remote monitoring and diagnosis system in this paper. According to the design principles of SOA, different levels and different granularity of services logic and functional requirements for remote monitoring and diagnosis system is divided, and a loosely coupled web services system is built. The design and implement methods of core function models about the proposed architecture is given in this paper. Finally, a demo system is used to validate the feasibility of the proposed architecture.
