摘要
本文讨论一种以PC系列微机为上位机的小型分布式系统中实时通信程序的设计方法,给出了设计思路和实现过程,并讨论了所采用的TSR结构的程序设计中的几点问题及解决途径。
In this paper,an application programming method of real-time communication among upper level IBM PC compatible microcomputer and the lower level field con trollers in typical small distribute system was presented. RS-232C asynchronous communication standard was used in our system and the communication software was developed under the MS-DOS,and was written in C language. To improve the real-time performance,we used TSR programming method. The whole system had the advantage of simple structure,reliable performance, and low cost. The detail design principle and the implementation of the system was presented,and some TSR programming problem and solution was also discussed.
