The network controller 14 receives a command of the logic controller 13 to effect switching between the first operating state and the second operating state. The first working state is as follows: the network controller 14 directly forwards the flue gas system data from the logic controller to the DCS control system, and the DCS control system controls the flue gas system; the second working state is as follows: the network controller 14 sends the flue gas system data from the logic controller 13 to the simulation server, the simulation server performs simulation calculation or optimization calculation, the simulated or optimized data is returned to the logic controller 13 through the network controller 14, and the logic controller 13 performs logic judgment to generate process control data of the flue gas system and transmits the process control data to the flue gas system so as to realize control of the flue gas system.

The simulation data refer to various data representing the flue gas system obtained by performing simulation calculation on the state data of the flue gas system, and the optimization data refer to various data representing the flue gas system in an optimized state obtained by further processing the simulation data. It can be seen that the simulation server 11 has both simulation and system optimization functions. By establishing various suitable simulation models, real-time simulation calculation can be carried out on various flue gas systems, and optimization data can be generated in real time. The optimization data is in turn returned to the logic controller 13 for generating data for the flue gas system process control, thereby enabling a convenient and efficient optimization control.
