| Abstract: | Application of PLC and inverter are introduced in this paper,in the heating boiler control system.The problems produced by boiler when working.The using of PLC and frequency conversion technique can solve those problems.The structure,working principle,operating mode,design of hardware and soft ware of this system are discussed in this paper.The choice of PLC,inverter and sensor are included in the hardware design.The distribution of I/O port,the distribution of number of I/O and the control circuit diagram of system are included in the software design.The problems such as the serious energy dissipation of heat-supplying,the poor stability,the labor intensity and the low automation are solved well in the new system.The stability,reliability,flexibility and the quality of heat-supplying are improved.and the effect of energy saving is obvious. |
