摘　　要：本文提出一种在分布式单片机控制系统中多机间进行高性能串行通讯的方案。采用RS-422标准及两级单片机主从式结构,实现了低成本、高速率、远距离、抗干扰性强的通讯。可应用于大多数进行多电机传动及协调控制的分布式单片机电气传动控制系统中多机实时通讯。A kind of high performance multi-computer serial communication scheme for distributed singlechip microcomputer control system is proposed. With RS-422 standard and two grade master-slave structure,advantages of low cost,high transmiting rate,long communicating distance and strong anti-disturbance are obtained. It can be applied to real-time multi-microcomputer communication in most of distributed single-chip microcomputer electric drive control systems which control and coordinate the drive speeds of all sections in the system.
