| Abstract: | The method increasing the sampling frequency will be adopted to make the system become a par_continuous one, using VFC and PWM as transforming elements A/D, D/A of the system in computer temperature measure and control. Which will effectively increase the precision and reduce the cost. |

| Keywords: | par_continuous VFC (Voltage Frequency Conversion) PWM(Pulse Width Modulation) |
