为降低生产成本,提高机台效率,完善管理考核手段,我们研制了用于卷烟机数据采集处理的两级微机系统。本文介绍系统的概况及硬件、软件的设计概要。一、系统组成及主要功能本系统由 Z-80系列的单板机构成前级机,TRS-80系列的系统机作为后级机,从而组成两级微机系统,实现对多台设备进行实时数据采集处理。其原理框图如图1所示。前级机选用 CMC-80型单板机,中央处理器为 Z-80,时钟频率2MHz,内存容量16K,其中8K ROM,8K RAM,I/O 接口有 CTC 一片,PIO 两片,SIO 一片,由高到低构成 CTC→PIO→
In order to reduce the production cost, improve the machine efficiency and improve the management and examination methods, we have developed a two-level computer system for the data acquisition and processing of cigarette machines. This article describes the system overview and hardware, software design summary. First, the system components and main functions The system consists of Z-80 series veneer machine into a former machine, TRS-80 series of system machines as a post-class machine, thus forming a two-tier computer system to achieve real-time data on multiple devices Acquisition and processing. The block diagram shown in Figure 1. CMC-80 front-end machine selection of single-board machine, the central processor for the Z-80, the clock frequency of 2MHz, the memory capacity of 16K, of which 8K ROM, 8K RAM, I / O interface CTC a PIO two, SIO one, From high to low form CTC → PIO →
