本文简要地介绍一种圆柱形分布式单片微计算机控制系统的结构、软件、应用和特点。一、系统的结构本分布式控制系统采用圆柱形结构。上端面由若干个结点组成环1,下端面由若干个结点组成环2,上下两个环的结点数量相同,并把两个环上的相应结点连接起来,组成一个圆柱形结构,如图1所示。系统中的每个结点分别采用 Intel 公司的 MCS-48系列的8039单片微型计算机。每个单片机包括2K×8位 EPROM(可扩展)、128×8位 RAM(可扩展)、8位内部定时器/计数器和27根 I/O 线(可扩展),其结构框图如图2所示。
This article briefly introduces a cylindrical distributed single-chip microcomputer control system structure, software, applications and features. First, the system structure The distributed control system uses a cylindrical structure. The upper end of the ring by a number of nodes 1, the lower end of the ring by a number of nodes 2, the upper and lower rings of the same number of nodes, and the two rings of the corresponding nodes connected to form a cylindrical structure ,As shown in Figure 1. Each node in the system uses Intel Corporation’s MCS-48 series of 8039 single-chip microcomputer. Each microcontroller includes 2K × 8 EPROM (expandable), 128 × 8 RAM (expandable), 8 internal timers / counters and 27 I / O lines (expandable), the block diagram shown in Figure 2 Show.
