Service-oriented design and implementation strategy of real-time distributed embedded control software

Real-time embedded Systems are core issue related to information technology and own huge application demand. This paper presents a service-oriented design methodology that reduces complexity by separating data-related computational parts and interaction among components. Architectures are composed hierarchically to manage embedded models and achieve real-time actor and architecture reuse. We introduce a notion of supervisor to manage the architecture and discuss how to aggregate individual component’s computation into a well-defined composite computation from a view of interaction semantics contract. A component-oriented hierarchically real-time quality analysis and processing control system of manufacturing data in Kunming Iron&Steel Co.Ltd.(KISC) is implemented to prove the feasibility and flexibility of our methodology.
