Design And Development Of DCS System Management Program

The thesis mainly studies the characteristics and structure of the Distributed Control System, analyzing the data communications between the monitoring layers, and network communications between the monitoring layers and Process control layer. The design of the system management program includes two parts: real-time database systems and network communication systems. In the development process of the real-time database, the thesis proposes the way of using shared memory file system for data communication, and using Windows Sockets function program for network communication, which is simple, reliable, and easy to implement.In program design and development process, object-oriented thinking has been brought into full play. This not only improves the efficiency of the system development, but also ensures the reliability of the program, so that software maintenance and modification become even more convenient.System Management program which provides data services for DCS monitoring layer software, is the bridge between the monitoring layer and control layer. The research and design of the system management program real-time data plat has the practical significance and value for the optimization of DCS system.
