摘要
介绍了一种标定温度计的标准恒温源,它以单片机为核心,利用单片机中比较器构造的单积分A/D模块采集温度传感器转换的温度输入信号,经单片机的脉宽调制处理输出控制信号至大功率三极管,使其发热至给定的温度。
A standard thermostat for thermometer calibration is introduced. It takes the single chip processor as the core.Input signal transformed by temperature sensor is collected with A/D module in the comparator.Through PWM of the single chip processor,output signal is given to transistor in order to gain stated temperature.
