ABSTRACT
 
This article introduced the electromagnetism stove principle of work and the design request, and proposed designs the electromagnetism stove with the AT90S8535 monolithic integrated circuit, and detailed introduction electromagnetism stove hardware, software realization process. The hardware mainly introduced the ventilator and the buzzer actuate the electric circuit, the electric current metering circuit, the voltage measurement electric circuit, the temperature survey electric circuit ,the IGBT tube control circuit, the host to control the board circuit analysis, finally uses Altium Designer6.5 software to simulate the hardware realization; Software partial mainly divides into the keyboard scanning, the demonstrates of kneading board control, the power control, the temperature control, the ventilator, the buzzer control, timed  control.
Key words: Electromagnetism stove; AT90S8535; Hardware; Software;
