在分布式控制系统中,采用PC机作为上位机,调度多台下位机,从而实现计算能力强,容量大的分布式控制系统.VB5.0为新一代上位机编程工具,其具有可视化编程特点,可实现良好的人机界面.该文介绍了用VB5.0实现与多台单片机通讯的原理、方法.%In a distributed control system (DCS), a PC is often used as a master unit, manipulating several Single?chip Microcomputers (slave units), and so a DCS with powerful caculation capability is formed. As a new generation of programming tools, VB5.0 has the virtues of visualizing and easily to build friendly man?machine interface. In this article, the methods and skills of constructing multi?machine communication are introduced.?
