两级控制模型

The Model of two classification control

利用 IBM—PC 与单板机 TP801的串行通讯,由 PC 控制单板机进而控制执行元件,实现远离现场的两级控制。文中介绍了两级控制的实用电路、串行通讯的参数设定、IBM—PC 通讯适配器的使用和编程方法。

This paper will introduce the se- rial transmission with the help of IBM-PC and TP801 computer,the achievement of two poles control far from the worksite by using the ex- ecutive-control implement in PC control single chip microcomputer,and also introduce the practical circut of two poles control,the parameter setting for the serial transmission, the use and programming of IBM-PC com- munication adapter.
