摘要
对总线结构的分布式测控系统中主从式和竞争式这两种基本通信方式作了介绍，并对单片机易直接实现的竞争方式所设计的一种新的解决方案进行了详细的讨论．描述了ＰＣ机作为上位机时与单片机通信接口的模拟问题．
Two basic communication models,master slave model and race model,used in distributed measure and control system based on bus organized structure,are introduced,and a new method designed for race model,which is difficultly implemented by single chip microprocessors directly,is discussed in detail.Simulation of communication interface between PC used as up processing machine and single chip microprocessors is also described.
