8031单片机多机系统的实时通信

Real Time Communication of Multimachine System Based on 8031 Single-chip Microcomputer

本文讨论了由8031单片机构成的多机系统间的实时串行数据通信。由于采用了中断方式和字符格式进行多机通信，解决了奇偶校验位与地址／数据位（TBS）间的矛盾、提高了系统的可靠性和实时性。文章还给出了通信程序的流程图。

In this paper,the real time communication multimachine system based on 8031 single - chip microcomputer is introduced. The contradiction between parity bit and address/data bit is solved as the interruption and character mode are used in the system. The reliability and the realizability of the multimachine system are both improved. The flowchart of communication program is also given in the paper.
