Design of the Monitoring Interface of Combustion Control System for Small-size Circulation Fluidized Bed Boiler

摘要

The combustion control system for small-size circulation fluidized bed boiler is a three-tier distributed control system. The system consists of host computer, master station and slave station. Master station synergizes slave station to complete control tasks, and sends process variables to host computer. Host computer functions as a friendly man-machine interface and shows running status. This paper completed the PC monitoring interface design for the small-size boiler combustion control system. The monitoring interface is based on MCGS touch screen. It mainly includes real-time parameter display, failure alarm, device control, parameter setting and real-time/history curve display.
