Abstract:Application of PLC and inverter are introduced in this paper,in the heating boiler control
problems produced by boiler when using of PLC and frequency conversion technique can solve those
structure,working principle,operating mode,design of hardware and soft ware of this system are
discussed in this choice of PLC,inverter and sensor are included in the hardware distribution of
I/O port,the distribution of number of I/O and the control circuit diagram of system are included in the software
problems such as the serious energy dissipation of heat-supplying,
