摘    要：集自动控制技术、计算机技术、数字通讯技术和CRT显示技术为一体的集散控制系统,合理地吸取了仪表控制和计算机集中控制的长处,并有效地克服了二者的缺陷,代表了当前过程控制系统的发展主流。作者描述了一种简易集散系统的通讯实现方法,并从软硬件设计方面进行了深入研究,解决了主机各任务之间的冲突,实现了从机对主机的主动通讯。

Abstract: Total distributed control system(DCS)represents the main trend of process controlsystem,which incorporates automatic control technology,computer technology,digital com-munication techriology and CRT display technology.It reasonably combines the advantagesof instrument control and computer-based centralized control,and effectivelv overcomestheir disadvantages.This paper deals with the realization of communication for a simple andpractical DCS system,in which the collision among the tasks in the master is solved and theiniative communication from the slave to master is realized,and also gives the design of itshardware and software.
