Abstract Aimed at the colorized glass plate production technology, a temperature control
system for glass sintering furnace is designed, in which the temperature must be changed
according to the given curve and the temperature control is multi-sectional. The system is
composed by CAN bus, industrial computer and intelligent node, which solves the puzzle of
precise control of multi-sectional temperature. In actual application, the system can control
temperature exactly for 18 ways as curve, and the difference in temperature is little, achieving the requirement of production technology completely.
