分布式控制系统中PC机和单片机的串行通讯设计

Design of Serial Port Communication Between PC and Single-chip Microprocessor in DCS

单片机系统应用日益广泛,数据通讯是单片机实现自动化控制的主要方式之一。而串口通讯又是单片机的主要通讯方式,给出了分布式控制系统中上位PC机与下位单片机之间进行异步串行通信的解决方案,并进行了相关的分析和讨论。

SCM system is more widely used,Data communication is one of the main methods of SCM automation control. SCM and serial communication is the main means of communication.This paper presents a distributed control system between the PC and the SCM for asynchronous serial communication solution,and the relevant analysis and discussion.
