基于组态王的基于组 wide range of applications, in a considerable number of field,
the electric boiler performance advantages and disadvantages of the decision The
quality of the boiler control systems currently used mostly for
computer control microprocessor core technology, both to improve the automation
equipment have improved the control precision equipment.
This paper on the heating boiler control system works, selection of temperature
transmitter, PLC configurations, the configuration software design aspects were
the transformation of electric boiler control system has fast
response, good stability, high reliability, control accuracy and good features, practical
significance for industrial control.
Key words: heating boiler control system temperature control cascade control
