摘要
介绍了一种供干炉温度自动控制系统．该系统的特点是：由单片８０３１作为ＣＰＵ，８２５５作为接口芯片，由８位ＬＥＤ组成显示器，通过ＭＣ１４４３３对温度信号采样，由双向可控硅控制执行电路，采用分段脉冲式控制方式来提高控温度精度。
This paper describes an oven temperature control system. The system consists of a CPU 8031, a parallel interface 8255, an 8-bit LED display and a temperature sampling interface MC14433. The executive circuit is controlled by a two-way SCR. Stepwise pulsed heating is used and the control precision is increased.
