摘要
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．
The temperature control of the producing process of a planar carrier catalytic element has been operated manually so far, which has influence on both identity and productivity of the element. Therefore, an automatic temperature control system based on microcomputer is proposed in this paper. The system consists of PC386 microcomputer, A/D converter, D/A converter and V/I conversion circuit. A new variable integral coefficient algorithm is also put forward. Both the objective temperature curve and the practical temperature curve can be displayed on the CRT at the same time. The experiments show that they coincide each other very well over the process.
