在1800kVA硅铁电炉上采用MDK-Ⅲ微型电子计算机控制供电系统(以下简称“微机控制系统”),是我厂与冶金部自动化研究所合作,共同研制并运用于过程控制的一项新技术。根据整机设计思想,我厂微控系统分为上、下两位机。上位机选用“苹果”微型机新型产品APPLE-Ⅱe,内存容量64kB,配14时CRT彩色显示器一台,5时磁盘驱动器两只,80行点阵打字机一台。下位机主要由电流、电压、功率变送器及功能模板等组成。上位机的主要功能是:上位机程序包括
In the 1800kVA ferrosilicon furnace using MDK-Ⅲ microcomputer control power supply system (hereinafter referred to as “microcomputer control system”), I plant and the Ministry of Metallurgical Institute of Automation, co-developed and applied to process control of a new technology. According to the whole design idea, our factory micro-control system is divided into upper and lower two machines. The host computer uses APPLE-IIe, a new product called “Apple” mini-computer, with a memory capacity of 64kB, a CRT color monitor with 14 hours, two disk drives at 5 hours and a dot matrix typewriter with 80 lines. Lower computer mainly by the current, voltage, power transmitter and function modules and other components. Host computer’s main function is: PC programs include
