本文介绍了微机邮件分拣系统的工作原理和硬件与软件的设计。这是一台实时控制和信息处理的微机系统,它的特点是控制规模大,可靠性要求高,输入输出的信号线达八百多根,而且大多数是30～50米的长线,不仅在技术上有一定的难度,而且在目前的微机实时应用中也具有一定的代表性。 This article describes the working principle of microcomputer mail sorting system and hardware and software design. This is a real-time control and information processing microcomputer system, which features large-scale control, high reliability requirements, the input and output signal lines up to more than 800, and most are 30 to 50 meters of long lines, not only in Technically a certain degree of difficulty, but also in the current computer real-time applications also have some representation.
