Realization Of Software Bus And Scheduling Of Open Control System

With the continuous development of science and technology, Automatization has becoming more and more important in industry and people. So research on real-time control system special open real-time control system is becoming more and more popular.Current commercial robot control systems are basically used the independent structure based on their own development, using special-purpose computers, special machine language, specific operating systems and microprocessor-specific features. This paper introduces a light weight service-oriented architecture (LSOA) .based open control system, which is loosely coupled, with flexibility of reconstruction. The system is based on a software bus core, which grantee the flexibility of reconstruction of the system.This paper proposed the whole framework of the control system based on LSOA firstly. The design and realization of the core components of the system will be describe in detail, which is software bus. The software bus is providing a mechanism to manage the service component in the system, monitor the status of the services and provide communicating support to services.Among all the features in the software bus, providing a operation flow control mechanism as a mediation between client and server and the real-time scheduling module are the most important parts. We discuss the theory basis the realization based on windows real time extension of this two parts in detail.Finally, a experiment with the PMAC and Servo Electromotor will be conducted to test the functionality and performance of the software bus.
