Network Based On Com / Dcom Middleware Platform For Distributed Computing And Its Implementation

With the development of Power Industry and Information Technology, in order to consummate Power Unit Control System, the research of power unit system become wider and wider.The work in this thesis is a part the "Power U.E.A Studio". Explore heterogeneous data mutual-operation technology and realization of distributed database, realize COM/DCOM structure, integration control, data communication and information resource share of the "Power U.E.A Studio".The research work of this thesis mainly includes:1) Discuss architecture of distributed database and physics realization, realize distributed heterogeneous data accessing through COM/DCOM; Analyze architecture of Mobile Agent and distributed database accessing based on Mobile Agent; Analyze distributed multiplayer application based on COM/DCOM, bring forward a network model of heterogeneous data mutual-operation.2) Discuss and realize the structure of distributed compute middleware; Analyze communication protocol of distributed compute middleware, and bring forward a model of self-determinated communication, realize the algorithmic design of communication; Analyze related security and fault tolerance.3) Discuss real-time data manipulate in Power Unit and definition of data accessing component interface; Design and realize distributed real-time database system in Power Unit; realize heterogeneous data mutual-operation based on COM/DCOM with Delphi; Analyze security in Power Unit data processing.Through the research of this project, having accumulated experience for designing platform of distributed heterogeneous data real-time manipulate.
