Abstract: Aiming at the characteristics and requirements of the complex industrial process modeling and simulation design, a suit of visual real-time simulation system for the typical process control was established and realized. The system integrates the functions of configuration, simulation and monitor, consists of the foreground user operations, the middle data communication and the background simulation. According to the concepts of oriented objects and modular design, the system integrates configuration and principle interface with Simulink model by VC++ programming, and thus realizes the visualization of process configuration graph and schematic, simulation, curve display and real-time communication with PLC, etc. Therefore, the system can be used to simulate the production process, set parameters, realize semi-physical simulation and learn process, etc. The experimental results show that this system has many advantages such as simple operation, beautiful interface, strong currency and convenient secondary development.  

Key words: visualization process control, configuration graph, schematic diagram, real-time simulation
