平面型载体催化元件制作过程的温度控制一直沿用手工操作，从而使元件的一致性与成品率受到较大影响．为此，研制了一种以微机为基础的温度自动控制系统．整个系统由ＰＣ３８６微机、Ａ／Ｄ、Ｄ／Ａ及Ｖ／Ｉ转换电路构成．在控制算法中，还提出了一种新的变积分系数的控制方法．目标温度曲线与实际温度曲线能同时显示在屏幕上．实验表明，两者能很好吻合，使元件制作达到了预期的效果．
Flat-type catalyst catalytic element manufacturing process temperature control has been followed by manual operation, so that the consistency of the components and the yield is greatly affected. To this end, developed a computer-based temperature control system. The entire system consists of PC386 microcomputer, A / D, D / A and V / I conversion circuit. In the control algorithm, a new control method of variable coefficient is also proposed. The target temperature curve and the actual temperature curve can be displayed on the screen at the same time. Experiments show that the two can be well matched, so that the production of components to achieve the desired results.
