Temperature control module and method thereof

摘要

Disclosed are a temperature control module (420) and a method thereof. An analogue input module, a PID control module, and an analogue output module are integrated as one module. The temperature control method comprises: determining a type of an analogue signal input to an input means (100) from preset parameters so as to control a temperature of an object; converting the analogue signal to a digital signal based on the type of the analogue signal; performing a PID control based on a measured temperature value of the digital signal and a predetermined target value thereby calculating a modulated value; generating a control signal of a pulse width modulation (PWM) control signal based on the modulated value and the preset parameter; and outputting the modulated value according to the PWM control signal.
