摘　　要：为解决旧式的控温器所存在的温度控制精度较差,控温效果达不到要求等问题,提出了一种利用μPD7810单片机制作温度控制系统的设计思想,设计了调温控制电路,采用PID温度控制调节方式,通过控制晶闸管的导通角来实现对温度的精密调节,并采用粗调及微调两个温度设定按钮,能方便地进行大范围温度设定,经实践证明控制效果很好,完全能满足工农业生产过程中的各类恒温需要,具有实际应用价值。To solve old type attemperators＇problems such as poor accuracy and low effects, the paper suggests a designing idea for the attemperater based on singlechip μPD7810 and devises the attemperation circuit by way of PID attemperation modulation, which realizes accurate attemperation by controlling the guiding angle of the crystal brake tube and applies the two buttons rorgh and fine tuning to attemperation in a wide range. The application has proved its good dffect. The system is able to meet various needs for constant temperatures in industrial and agricultural production processes and has practical value.
